Vertebral hemangiomas are common benign vascular tumors of the spine. It is very rare for these lesions to symptomatically compress neural elements. If spinal cord compression does occur, it usually involves only a single level. Multilevel vertebral hemangiomas causing symptomatic spinal cord compression have never been reported in the pediatric population to the best of our knowledge. We report the case of a 15-year-old boy presenting with progressive paraparesis due to thoracic spinal cord compression from a multilevel thoracic hemangioma (T5-T10) with epidural extension. Because of his progressive neurological deficit, he was initially treated with urgent multilevel decompressive laminectomies from T4 to T11. This was to be followed by radiotherapy for residual tumor, but the patient was unfortunately lost to follow-up. He re-presented 3 years later with recurrent paraparesis and progressive disease. This was treated with urgent radiotherapy with good response. As of 6 months follow-up, he has made an excellent neurological recovery. In this report, we present the first case of a child with multilevel vertebral hemangiomas causing symptomatic spinal cord compression and review the literature to detail the pathophysiology, management, and treatment of other cases of spinal cord compression by vertebral hemangiomas.

Pregnancy-related compressive myelopathy secondary to vertebral hemangioma is a rare occurrence and its treatment antepartum is rare. A 19-year-old North African woman in her 38th week of pregnancy presented with paraplegia that progressed within 2 days after a rapidly progressive weakness of her lower limbs. Magnetic resonance imaging studies showed compression of her spinal cord in front of the fourth thoracic vertebra for suspected tuberculous spondylitis. A Caesarean section was done followed by corpectomy with a bone graft because we intraoperatively discovered a vertebral hemangioma. Pathology showed an aggressive hemangioma. At any term of pregnancy, extensive neurological involvement which is rapidly progressive due to compression should be considered for immediate decompression.

Vertebral hemangiomas are benign vascular lesions of the vertebral column; only 0.9-1.2% of all vertebral hemangiomas cause spinal cord compression. We report a 34-year-old female who was admitted to the neurosurgery clinic with a history of back pain, poor quality of life and easy fatigability for 1.5 years. Her medical history revealed a fall from a height of 2 meters 1.5 years ago. Neurology examination revealed bilateral hypoesthesia below the T8 level and hyperactive deep tendon reflexes in her left leg. Computed tomography scan of the thoracic spine showed T8 vertebral hemangioma, and magnetic resonance imaging showed a T8 hemangioma compressing the spinal cord. Surgical intervention was planned and T8 total laminectomy was performed. The tumor extending into the anterior spinal cord was resected, and T8 vertebroplasty with short segment posterior stabilization and fusion was performed. We aimed to present a new treatment approach for symptomatic vertebral hemangiomas and reviewed the relevant literature.

Vertebral hemangiomas are benign vascular tumours of the bony spine which are usually asymptomatic. Pregnancy-related anatomical and hormonal changes may lead to expansion of hemangiomas and development of neurological symptoms. We present an unusual case of vertebral fracture due to an undiagnosed hemangioma presenting as postpartum back pain following epidural analgesia. A multiparous female with an unremarkable history developed intense lumbar pain after vaginal delivery under epidural analgesia. The pain was attributed to tissue trauma associated with the epidural technique. The patient had no clinical improvement with analgesics, and her symptoms deteriorated over the following days. A magnetic resonance imaging scan revealed an acute fracture of the second lumbar vertebra (L2) with epidural extension and mild compression of the dural sac, suggesting hemangioma as the underlying cause. The patient underwent successful spinal surgery with pedicle screw fixation to stabilize the fracture. Vertebral fractures secondary to acute expansion of a vertebral hemangioma rarely occur during vaginal delivery. In such cases, the labour epidural technique and analgesia may challenge the physician in making the diagnosis. Postpartum severe back pain should be thoroughly investigated even in the absence of neurological deficits, and osseous spinal pathology should be considered in the differential diagnosis.

To provide useful insights of multidisciplinary surgical treatment for vertebral hemangioma with spinal cord compression. From 2009 to 2014, data on six patients who were diagnosed with cord compression vertebral hemangioma were reviewed and analyzed retrospectively. There were five women and one man with a mean age of 48.6 years (range, 26-68 years). All the patients were treated by multidisciplinary approach, including use of gelfoam, pedicle screw instrumentation, vertebroplasty, and decompression laminectomy. Neurological status and Frankel grades were documented, CT scan and MRI were performed after surgery. The follow-up period ranged from 8 to 54 months. Mean blood loss was around 367 mL, and the mean surgical time was 2.30 h. All patients had uneventful intraoperative and postoperative courses and reported symptomatic and neurological relief to varying degrees, at an average follow-up period of 23 months. Bone cement distribution was disseminated homogeneously over the affected vertebra and no leakage was observed. All the patients had a complete restoration to Frankel grade E. The postoperative and follow-up imaging showed that the implant was in perfect position, and no recurrence occurred in all patients. The vertebral hemangioma with cord compression is a challenge to surgeons for therapeutic improvement, and an active involvement of several disciplines as well as performance of multidisciplinary surgical treatment can be crucial in achieving favorable results. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

Vertebral hemangiomas are common; however, aggressive vertebral hemangiomas with extraosseous extensions causing neurological deficits are rare. The treatment for this subtype of hemangioma remains controversial, since there are few reports on long-term clinical outcomes or tumor recurrence rates. We describe a case of aggressive vertebral hemangioma treated by total en bloc spondylectomy, with a literature review focusing on long-term recurrence. A 52-year-old male with a two-month history of numbness in the bilateral lower extremities was referred to our hospital. Imaging studies showed a tumor originating in the T9 vertebra and extending to the T8 and T10 vertebrae, with extraosseous extension causing spinal-cord compression. Ten months after onset, the patient presented with progressive paraparesis and hypalgesia. Total en bloc spondylectomy was performed, and pathology was consistent with cavernous hemangioma. Motor and sensory deficits improved significantly, and no signs of recurrence are seen at 2.5 years after operation. A review of literature revealed a recurrence rate of 12.7% (10/79 cases). The available evidence indicates satisfactory long-term outcomes for total tumor resection without adjuvant radiotherapy. PMID:25918662

A vertebral hemangioma with dural compression and neurological deficit is rare. We report a symptomatic lumbar vertebral hemangioma which was successfully managed with total spondylectomy. The patient was a 31-year-old man whose chief complaint was low back pain. He had a slight sensory disturbance in the right thigh. Plain radiography and magnetic resonance imaging (MRI) revealed a tumor in the second lumbar vertebra, which extended into the spinal canal, compressing the dura. A percutaneous needle biopsy did not provide a pathological diagnosis. Before surgery, the arteries feeding the tumor were embolized using coils. We performed a total spondylectomy of the second lumbar vertebra with anterior reconstruction with a glass ceramic spacer and posterior instrumentation. The intraoperative pathological examination revealed a hemangioma of the lumbar spine. At the 4-year follow-up examination, the patient is completely asymptomatic without evidence of tumor recurrence.

Although cavernous hemangiomas occur frequently in the intracranial structures, they are rare in the spine. Most of spinal hemangiomas are vertebral origin and "pure" epidural hemangiomas not originating from the vertebral bone are very rare. Our spinal hemangioma case is extremely rare because of its "pure" epidural involvement and intralesional hemorrhage. A 64-year-old man presented with progressive paraparesis from two months ago. His motor weakness was rated as grade 4/5 in bilateral lower extremities. He also complained of decreased sensation below the T4 sensory dermatome, which continuously progressed to the higher dermatome level. Magnetic resonance imaging demonstrated thoracic spinal tumor at T3-T4 level. The tumor was located epidural space compressing thoracic spinal cord ventrally. The tumor was not involved with the thoracic vertebral bone. We performed T3-5 laminectomy and removed the tumor completely. The tumor was not infiltrating into intradural space or vertebral bone. The histopathologic study confirmed the epidural tumor as cavernous hemangioma. Postoperatively, his weakness improved gradually. Four months later, his paraparesis recovered completely. Here, we present a case of pure spinal epidural cavernous hemangioma, which has intralesional hemorrhage. We believe cavernous hemangioma should be included in the differential diagnosis of the spinal epidural tumors. PMID:25110490

Vertebral hemangiomas are common lesions and usually considered benign. A rare subset of them, however, are characterized by extra-osseous extension, bone expansion, disturbance of blood flow, and occasionally compression fractures and thereby referred to as aggressive hemangiomas. We present a case of a 67-year-old woman with progressive paraplegia and an infiltrative mass of T4 vertebra causing mass effect on the spinal cord. Multiple conventional imaging modalities were utilized to suggest the diagnosis of aggressive hemangioma. Final pathologic diagnosis after decompressive surgery confirmed the diagnosis of an osseous hemangioma.

Pregnancy related compressive myelopathy secondary to vertebral hemangioma is a rare occurrence and its treatment antepartum is rare. We report a 22-year-old lady in her 26th-week of pregnancy who was treated in two stages--antepartum with a laminectomy and posterior stabilization. This resulted in complete recovery of the neurological deficits. She delivered a normal baby after 3 months, following which a corpectomy and fusion was performed. This two-staged approach appears safe and effective in treating symptomatic vertebral haemangiomas causing neurological deficits during pregnancy. A review of relevant literature has been done.

Case report and clinical discussion. We intend to report a very rare case of a giant spinal hemangioma causing myelopathy. Multilevel symptomatic spinal hemangiomas causing acute neurologic symptoms are rare disorders. We found only sporadic reports in English literature. We describe a very rare case in which Klippel-Trenaunay-Weber syndrome is associated with a multisegmental vertebral hemangioma causing a rapidly progressing thoracic myelopathy. Because of the extension of the disease, surgical intervention was not feasible, the patient was treated by radiotherapy. The patient showed a complete regression of symptoms with stable condition after 3 months. In extensive spinal hemangiomas, radiotherapy may represent a safe treatment modality with rapid clinical improvement even in cases with spinal cord compression. This report contributes to a wide range of known vascular abnormalities in Klippel-Trenaunay-Weber syndrome and supports the need for a careful multisystemic evaluation of these patients.

Context Hemangiomas are the commonest benign tumors of the spine. Most occur in the thoracolumbar spine and the majority are asymptomatic. Rarely, hemangiomas cause symptoms through epidural expansion of the involved vertebra, resulting in spinal canal stenosis, spontaneous epidural hemorrhage, and pathological burst fracture. Findings We report a rare case of a 73-year-old woman, who had been treated for two months for degenerative neurogenic claudication. On admission, magnetic resonance imaging and computed tomographic scans revealed a hemangioma of the third lumbar vertebra protruding to the epidural space producing lateral spinal stenosis and ipsilateral nerve root compression. The patient underwent successful right hemilaminectomy for decompression of the nerve root, balloon kyphoplasty with poly-methyl methacrylate (PMMA) and pedicle screw segmental stabilization. Postoperative course was uneventful. Conclusion In the elderly, this rare presentation of spinal stenosis due to hemangiomas may be encountered. Decompression and vertebral augmentation by means balloon kyphoplasty with PMMA plus segmental pedicle screw fixation is recommended.

Case report. To report a case of lumbar hemangioma causing neurogenic claudication and early cauda equina, managed with hemostatic vertebroplasty and posterior decompression. This is the first report to our knowledge of a lumbar hemangioma causing neurogenic claudication and early cauda equina syndrome. Most hemangiomas causing neurologic symptoms occur in thoracic spine and cause spinal cord compression. Vertebroplasty as a method of hemostasis and for providing mechanical stability in this situation has not been discussed previously in the literature. L4 hemangioma was diagnosed in a 64-year-old woman with severe neurogenic claudication and early cauda equina syndrome. Preoperative angiograms showed no embolizable vessels. Posterior decompression was performed followed by bilateral transpedicular vertebroplasty. The patient received postoperative radiation to prevent recurrence. Complete relief of neurogenic claudication and cauda equina with less than 100 mL of blood loss. A lumbar hemangioma of the vertebral body, although rare, can cause neurogenic claudication and cauda equina syndrome. Intraoperative vertebroplasty can be an effective method of hemostasis and provide stability of the vertebra following posterior decompression.

Osseous epithelioid hemangioma is uncommon, and reports of epithelioid hemangiomas of the spine are especially rare. Case report. A 43-year-old male was referred to our department with progressive gait disturbance. CT scans showed a lucent mass in the vertebral body at the T3 level. MRI of the thoracic spine showed a strongly enhanced mass compressing the spinal cord. The patient underwent laminectomy from T2 to T4, debulking of the tumor, and posterior fusion from T1 to T5. After the operation, the patient's neurological status improved significantly, and he was able walk without assistance. Histological examination determined that the tumor was an epithelioid hemangioma. The patient was treated with 40 Gy radiation for local control of the tumor. The patient could walk without difficulty 12 months after the surgery. This is a rare example of an epithelioid hemangioma that developed in the thoracic spine and compressed the spinal cord, and was treated successfully.

Vertebral hemangiomata are ubiquitous bone tumors. Often multiple, they are generally benign in nature and slow growing. They typically have a predictable radiographic appearance. Occasionally, hemangiomata may behave in a more aggressive manner, causing pathologic fracture or even symptoms/signs of nerve compression. In such cases, one must be careful not to assume that an atypical hemangioma is responsible. Coexisting, more malignant processes may be present and sometimes may be radiographically undetectable in the setting of acute fracture. This was the case in our patient. Case report/university spine surgery center. The patient underwent a corpectomy of her affected vertebra with conversion to a total spondylectomy when intraoperative frozen section was consistent with plasma cell neoplasm. A reconstruction with vertebral body replacement and fusion through anterior and posterior approaches was completed. Subsequently, the literature was reviewed for other cases of atypical hemangiomata to investigate the incidence of coexistent lesions. This patient presented with pain secondary to an unstable pathologic vertebral body fracture. Surgery to stabilize her spine was elected. Intraoperative recognition of abnormal-appearing tissue led to the diagnosis of a plasma cell neoplasm that was not seen on imaging. Coexistent in the same vertebra was hemangiomatous tissue that was visible on preoperative imaging. There are rare reports of aggressively behaving hemangiomata that mainly have occurred in the thoracic spine. There have been no reports of the coexistence of a hemangioma and a plasma cell tumor in the same vertebral level in the setting of acute compression fracture. Copyright © 2013 Elsevier Inc.

We describe a very unusual vertebral hemangioma presenting with a mixture of aggressive-like pattern (epidural extension, T1 hyposignal) and quiescent, inactive lesion (fatty infiltration), in association with a spiculated calcified epidural component.This paper emphasizes that CT and/or MR findings are accurate enough to make formal assessment of vertebral hemangioma, preventing patient's anguish and moreover unnecessary treatment. Furthermore this attractive case proposes a poorly known characteristic of vertebral hemangioma which is usually encountered and described only in skull hemangiomas.

Conservative management of maternal cervical vertebral hemangioma complicating pregnancy.
Foster, Leah; Davidson, Kathryn; Egerman, Robert
2015-03-01
Although vertebral hemangiomas are found in 10% of the population, they rarely become symptomatic. We describe management of an enlarging cervical vertebral hemangioma during pregnancy. A primiparous woman at 33 weeks of gestation presented with neck pain and paresthesias. She had a known cervical hemangioma. Imaging revealed a C6-C7 hemangioma with extradural extension. Her symptoms fluctuated, and she was delivered by cesarean at 36 weeks of gestation. Improvement occurred after delivery, and radiographic regression of the hemangioma was demonstrated. Hormonal and vascular changes of pregnancy may exacerbate spinal hemangiomas. Depending on the location, these may lead to profound neurologic disability and management depends on the degree of myelopathy. Surgical intervention may be necessary to avoid neurologic injury, but amelioration after delivery is possible.

The authors report on colon cancer metastasis to the L-3 vertebra, which had been previously found to be involved by an asymptomatic hemangioma. A 61-year-old female patient was admitted after onset of lumbar axial pain and weakness of the right quadriceps muscle. Her medical history included colon cancer that had been diagnosed 3 years earlier and was treated via a right hemicolectomy followed by chemotherapy. Presurgical imaging revealed an asymptomatic hemangioma in the L-3 vertebral body. Computed tomography and MRI of the spine were performed after admission and revealed a hemangioma in the L-3 vertebral body as well as a soft-tissue mass protruding from the L-3 vertebral body to the spinal canal. Treatment consisted of vertebroplasty of the hemangioma, left L-3 hemilaminectomy, and removal of the pathological mass from the spinal canal and the L-3 vertebral body. Histopathological examination revealed the presence of colon cancer metastasis and a hemangioma in the same vertebra.

Vertebral body (VH) hemangiomas with myelopathy are difficult to manage. To evaluate the role of intra-operative ethanol embolization, surgical decompression and instrumented short segment fusion in VH with myelopathy and long-term outcome (>24 months). Prospective study: Symptomatic VH with cord compression with myelopathy. Excluded: pathological fractures, and/or deformity or multi-level pathologies. Surgery consisted of intra-operative bilateral pedicular absolute alcohol (<1% hydrated ethyl alcohol) injection, laminectomy and cord decompression at the level of pathology followed by a short segment instrumented fusion using pedicle screws. 33 patients (Mean 26.9 + 13.2, range: 10-68 years, 18 females). myelopathy all (5 paraplegic), sphincter involvement (13), and mid back/ lower pain (7). Pre-operative American Spinal Injury Association (ASIA) scores: A(7), B(11), C(6), D(8) and E(1). Majority had single vertebral involvement (30), 3 multiple level. Six underwent surgery earlier (1 alcohol embolization here). Mean surgical time: 124+39 minutes, average blood: 274+80 cc. Mean amount of absolute alcohol injected: 14.6+5.7 cc. (2 requiring 20 & 25 cc). Immediate embolization achieved in all, allowing laminectomy and soft-tissue hemangioma removal easily. Post-surgery, 1 patient had transient deterioration, rest all patients improved (sphincters improved in 9) at a follow up ranging 28-103 months (mean 47.6+22.3). Follow-up ASIA scores: E(26), D(4), B(2) & C(1). All patients showed evidence of bone sclerosis and relief of cord compression on follow-up imaging. This is largest study in literature showing excellent improvement, low re-operation rates following ethanol embolization and short segment fixation. Copyright © 2018. Published by Elsevier Inc.

The vertebral hemangiomas are benign vascular lesions occurring in spine. Although uncommon, symptomatic vertebral hemangiomas can be painful and can limit daily activities. A number of methods have been used in the treatment of symptomatic and aggressive vertebral hemangioma, but none of them is optimal. Treatment with cement vertebroplasty showed very good results. This study aims to illustrate the validity of the treatment with cement vertebroplasty in patients with painful vertebral hemangiomas. From January 2000 to January 2007, 24 patients were treated by percutaneous vertebroplasty because of hemangioma: 16 thoracic, 8 lumbar. There were 11 males and 13 females. The average age at the time of surgery was 48 years. All the patients complained of a pain syndrome resistant to continuing medication. All patients underwent X-ray examination, CT-scan and MR of the involved level preoperatively. A unipedicular approach under fluoroscopic guidance has been performed in all patients. All procedures have been carried out under the local anesthesia. The mean follow-up was 5.8 years. In all the patients a successful outcome has been observed with a complete resolution of pain symptom. Extravertebral vascular cement leakage has been observed in 3 patients, without any clinical radicular syndrome onset due to the epidural diffusion. Clinical and radiological follow-up showed stability of the treatment and absence of pain in all patients. Percutaneous treatment with vertebroplasty for symptomatic vertebral hemangiomas is a valuable, less-invasive, and a quick method that allows a complete and enduring resolution of the painful vertebral symptoms without findings of the vertebral body's fracture.
Incidence of vertebral hemangioma on spinal magnetic resonance imaging in Northern Iran.
Barzin, M; Maleki, I
2009-03-15
The incidence of vertebral hemangiomas as the most common benign spinal neoplasms has been differently reported from 10 to 27% based on autopsy series, plain X-rays and MRI reviews. In this study, we reviewed consecutive 782 standard spinal MRI with axial and sagital T1 weighted and T2 weighted images looking for hemangiomas. In this study, the incidence of hemangioma was 26.9%, more common in females (30%) than males (23%), in older age group and in lumbar spine. Most hemangiomas (65%) were less than 10 mm in diameter. Multiple hemangiomas were seen in 33% of cases. The results of this study are similar to another Mediterranean study reported based on MRI findings, but differ from other reports using X-ray or autopsy as diagnostic tool, suggesting the influence of either the race or the sensitivity of the diagnostic tool on the incidence of vertebral hemangioma.

Over the last 10 years, there has been much development in the management of metastatic and osteoporotic vertebral compression fractures using vertebroplasty. This percutaneous image-guided interventional radiology procedure allows stabilization of a vertebral body by injection of an acrylic cement and frequently results in significant symptomatic relief. During cement polymerisation, an exothermic reaction may destroy adjacent tumor cells. Advances have been made to reduce complications from extravasation of cement in veins or surrounding soft tissues. Safety relates to experience but also to technical parameters: optimal cement radio-density, adequate digital fluoroscopy unit (single or bi-plane digital angiography unit), development of cements other than PMMA to avoid the risk of adjacent vertebral compression fractures. The rate of symptomatic relief from vertebroplasty performed for its principal indications (vertebral hemangioma, metastases, osteoporotic fractures) reaches 90-95%. The rate of complications is about 2% for metastases and less than 0.5% for osteoporotic fractures. Vertebroplasty plays a major role in the management of specific bone weakening vertebral lesions causing, obviating the need for kyphoplasty.

The authors present a rare case of lumbar vertebral hemangioma extending to the epidural space with a bisected appearance and impinging on thecal sac. This 52-year-old lady presented with one year history of low back pain and bilateral leg radiation. Plain radiography showed vertical linear streaks at L2 vertebral body and axial computed tomography (CT) scan revealed small "polka dot" appearance within the vertebral body. Magnetic resonance imaging (MRI) showed low signal intensity on T1-weighted images in L2 vertebral body which was not characteristic for hemangioma. The patient underwent an L2 laminectomy, spinal canal decompression and posterior spinal instrumentation. This study indicates that lumbar vertebral hemangioma can extend to the epidural space and cause neurologic symptoms. Magnetic resonance imaging may not show diagnostic features, especially in active lesions and plain radiography and CT scan may be helpful.

Vertebral hemangiomas (VHs) are frequently asymptomatic lesions found incidentally during investigations for other spinal problems. Symptomatic VHs are less common, and there are few reports of compressive VHs in the literature. VHs with aggressive behavior present with low signal intensity on T1-weighted and high signal intensity on T2-weighted MRI. We present a case series of four patients with compressive VH, all of whom were neurologically compromised. Each of the four patients underwent preoperative arterial embolization followed by surgical treatment of their VHs. All patients recovered normal motor function after surgery. At follow-up (average 53 months), one patient had a recurrent tumor requiring reoperation and radiotherapy. Although it is rare, aggressive VH can be a devastating condition. Total surgical resection or subtotal resection with radiotherapy may be warranted. Copyright © 2010 Elsevier Ltd. All rights reserved.

Back pain prevalence in the pediatric age group is less compared with adults. There is a wide range of possible etiologies, and tumors such as primary spinal hemangiomas are uncommon. Most are incidental findings and asymptomatic; however, painful lesions can be presented in up to 0.9% to 1.2% of cases. These lesions can produce neurologic involvement either spinal cord compression or cauda equina syndrome as in our case. The aim of this study is to describe a case of low back pain in a child due to a vertebral hemangioma complicated with acute cauda equina syndrome, and performed a literature review that will help us to recognize this aggressive variance making an early treatment feasible. A 13-year-old female, follow-up in an outer health care center due to a L1 vertebral hemangioma, characterized by 3 years of low back pain without neurologic symptoms presented to our emergency department with an acute cauda equina syndrome. An outside magnetic resonance imaging showed complete obliteration of the spinal canal at the level of the conus medullaris related to retropulsion of bone at L1. She underwent 2-stage surgical treatment: complete posterior L1 laminectomy and partial T12-L2 laminectomies, with partial L1 vertebrectomy and posterior fusion with instrumention from T11 to L3. Three weeks later, embolization before anterior fusion with inner body cage was performed. Forty months after surgery, she is doing well with no neurologic deficits. Even though hemangiomas are not a common cause of back pain, they should be taken into account. It is important to recognize the aggressive variance so an early treatment could be performed. There is no enough clinical data to establish guidelines of management in children, therefore, the treatment should be individualized.

A 74-year-old man with newly diagnosed prostate cancer underwent Ga-PSMA PET/CT, which demonstrated intense uptake in and adjacent the L2 vertebral body. Subsequent MRI of the lumbar spine showed an aggressive L2 hemangioma with adjacent soft tissue extension. There was congruence of the intraosseous and extraosseous components of the hemangioma and the PSMA PET uptake. This is a rare but important potential pitfall in Ga-PSMA PET/CT-a soft tissue lesion with intense tracer uptake related not to a nodal metastasis of prostate cancer but to extraosseous extension of an aggressive vertebral body hemangioma.

To describe the surgical experience of spondylectomy and spinal reconstruction for aggressive vertebral hemangioma (VH) induced at the C4 vertebra. No reports have described surgical strategy in cases covering an entire cervical vertebra presenting with progressive myelopathy. A 28-year-old man presented with rapidly progressing skilled motor dysfunction and gait disorder. The Japanese Orthopedic Association (JOA) score was 6. Radiography showed a honeycomb appearance for the entire circumference of the C4 vertebra. Spinal computed tomography and magnetic resonance imaging showed vertebral tumor with extraosseous extension causing spinal cord compression. Results of diagnostic imaging were strongly suggestive of VH. Transarterial embolization of the spinal body branch was performed first to decrease intraoperative bleeding, followed by cervical posterior fixation to stabilize the unstable segment and excision biopsy to obtain a definitive diagnosis. After definitive diagnosis of cavernous hemangioma, two-stage surgery (anterior and posterior) was performed to complete total spondylectomy and 360° spinal reconstruction. Despite multiple operations, JOA scores were 8.5 after posterior fixation, 10.5 after anterior surgery, 11 after final surgery and 16 on postoperative day 90. The patient acquired excellent clinical results without complications and returned to society. The present three-stage surgery comprising fixation, biopsy, and final spondylectomy with circumferential fusion from anterior and posterior approaches may offer a useful choice for aggressive VH covering the entire cervical spine with rapidly progressive myelopathy.

In contrast to vertebral hemangiomas, which are very common within the general population, only 3% to 5% of patients with plasma cell dyscrasia show a single osteolytic bone lesion due to plasma cell infiltration without the evidence of generalized myeloma. The vast majority of these hemangiomas are completely asymptomatic and only discovered incidentally. In rare occasions, representing only 1% to 2% of the known lesions, a locally aggressive subtype can cause problems analogous to the ones triggered by a plasmocytoma, ranging from back pain to vertebral compression fractures to neurologic deficit, resulting from nerve root or spinal cord compression. Both entities are extensively discussed in the literature, but finding both lesions in one is rare if not described for the first time. To advise colleagues that the differential diagnosis between benign and malignant vertebral tumors can be harder than expected and has to be definitely made to avoid severe consequences for the patient. A 46-year-old healthy man presented to the emergency department with an acute onset of thoracic back pain after a trivial incident. Although his medical history included no known diseases and no history of back pain, plain X-rays raised the clear suspicion of a fracture of T6 that was verified in computed tomography scans. Visual analog scale; neurologic status; tumor recurrence. The case of the patient was evaluated retrospectively according to standard procedures, clinical outcome, and in review of the literature. Because there is still controversy about the best treatment (local radiation vs. operation vs. combination) of a solitary skeletal plasmocytoma, no gold standard has been established until now. Especially if a patient needs an emergency operation before all test results are obtained, each surgeon has to decide individually. Capillary hemangiomas can hide underlying plasmocytomas, which might demand totally different treatment strategies. Although our patient did not match the common criteria for a solitary plasmocytoma, one has to discuss whether a stand-alone decompression and biopsy would have been the emergency treatment of choice. Such a strategy would have reduced the risk of tumor spreading and would have made radiotherapy easier, whereas on the other hand requiring a secondary stabilization procedure later on.

BACKGROUND Despite being the most common tumor of the spine, vertebral hemangioma is rarely symptomatic in adults. In fact, only 0.9-1.2% of all vertebral hemangiomas may be symptomatic. When hemangiomas occur in the thoracic vertebrae, they are more likely to be symptomatic due to the narrow vertebral canal dimensions that mandate more aggressive management prior to the onset of severe neurological sequelae. CASE REPORT An 18-year-old male presented to the emergency room with a one-month history of mild to moderate mid-thoracic back pain, radiating to both lower limbs. It was associated with both lower limb weakness and decreased sensation. There was no history of bowel or bladder incontinence. Neurological examination revealed lower limb weakness with power 3/5, exaggerated deep tendon reflexes, bilateral sustained clonus, impaired sensation below the umbilicus, spasticity, and a positive Babinski sign. A CT scan showed a diffuse body lesion at the 8th thoracic vertebra with coarse trabeculations, corduroy appearance, or jail-bar sign. The patient underwent decompression and fixation. Biopsy of permanent samples showed proliferation of blood vessels with dilated spaces and no malignant cells, consistent with hemangioma. Postoperatively, spasticity improved, and the patient regained normal power. CONCLUSIONS Symptomatic vertebral hemangiomas are rare but should be considered as a differential diagnosis. They can present with severe neurological symptoms. When managed appropriately, patients regain full motor and sensory function. Decompression resulted in quick relief of symptoms, which was followed by an extensive rehabilitation program.

Vertebral hemangiomas are the most common benign vertebral neoplasms and are generally asymptomatic. In the present study, we report the case of a 52-year-old male master ultra-marathoner suffering from a pathologic fracture of the thoracic spine due to a vertebral hemangioma. A further examination in the athlete revealed an accompanying osteopenia, which was most likely due to a deficiency in both vitamin D and testosterone. The treatment of the fracture consisted of percutaneous vertebroplasty. Shortly after the operation the athlete was able to continue running. The most likely reason for the pathologic fracture of the vertebral body was the combination of the vertebral hemangioma and osteopenia. The further treatment consisted of supplementation of both vitamin D and testosterone. Athletes and physicians should be aware that male master ultra-marathoners older than 50 years might suffer from osteopenia, where a deficiency in vitamin D and testosterone could be contributing factors for osteopenia development in general.

Retrospective study. To analyze our experience in the treatment of symptomatic vertebral hemangioma, review the relevant literature, and propose a management algorithm. Hemangioma is one of the commonest benign neoplasms affecting the vertebral column. These usually dormant lesions may become symptomatic by causing pain, neurologic deficit, or both. Several treatment modalities are available in the management of such symptomatic conversion. The clinical and radiographic data of 6 patients diagnosed with symptomatic vertebral hemangioma and treated at our medical center over a period of 10 years were reviewed and analyzed retrospectively. Six patients were diagnosed with symptomatic vertebral hemangioma between 1998 and 2008. The lesions occupied the thoracic, lumbar, or multiple segments. Our patients presented with either simple or radicular back pain. One patient had muscle weakness, 3 revealed sensory impairment, and the remaining 2 were neurologically intact. Four patients underwent preoperative transarterial embolization followed by laminectomy and vertebroplasty of the affected level and 2 patients were treated with vertebroplasty alone. A 35-year-old woman presented during pregnancy. Her clinical course during evaluation was complicated by an acute pulmonary embolic event that necessitated installation of an inferior vena cava filter. All patients had an overall uneventful postoperative course and reported symptomatic relief to varying degrees, at an average follow-up period of 35 months. Symptomatic hemangioma involving the vertebral column may pose a therapeutic challenge, often requiring the active involvement of several disciplines. A review of the relevant literature, however, discloses only few management algorithms for such lesions. The coupling of preoperative transarterial embolization followed by vertebroplasty, with or without surgical decompression depending on the patients' presenting symptoms, is a relatively safe treatment and may offer long-term symptomatic relief in these patients. Other aspects of treatment are further discussed.

A number of methods have been used in the treatment of symptomatic and aggressive vertebral hemangioma, but none of them is optimal. Vertebral hemangioma treated with cement vertebroplasty or ethanol injection alone showed relatively good results despite their limitations. Between February 2002 and May 2004, twelve patients with vertebral hemangioma were subjected to combined cement vertebroplasty and ethanol injection, five of them were men and seven women, and aged from 26 to 54 years (mean, 41 years). The following levels of the spine were involved: T9: 1, T10: 3, T12: 2, L1: 1, L2: 2, L3: 2 and L4: 1. The clinical results and radiographic records of the patients were assessed after 2 years and 5 months of follow-up. The average score of back pain significantly decreased from 6.5 before operation to 1.7 one month after operation. No severe complications occurred during and after operation. During the period of follow-up, symptoms were not deteriorated. At the end of follow-up, neither radiographic sign of aggressive destruction nor collapse of the involved vertebra was observed. Significant improvement in the 12 patients was demonstrated on 7 of 8 SF-36 Health Scale except for mental health. Cement vertebroplasty combined with ethanol injection as a safe and effective technique is an alternative to the treatment of patients with vertebral hemangioma.

The case of a 70-year-old woman with progressive renal cell carcinoma (RCC) metastatic invasion of a L3 vertebral hemangioma treated by dual percutaneous radiofrequency ablation (RFA) and vertebroplasty is reported. The patient was surgically treated for RCC in 2001. Chemotherapy and immunotherapy were introduced in 2013 for ovarian, bladder and cerebral metastatic disease. An asymptomatic L3 benign hemangioma was noticed at this time. One-year CT and MRI follow-up studies demonstrated a nodular isolated soft tissue lesion involving the anterior edge of the hemangioma. Percutaneous treatment consisted of a L3 vertebral body unipedicular approach to perform a biopsy, RFA with a navigational bipolar RFA device and vertebroplasty using high viscosity cement. Histopathological examination confirmed metastasis of RCC. The 5-month spinal MRI and CT examinations demonstrated complete disappearance of the tumor. 2017 BMJ Publishing Group Ltd.

To investigate the treatment methods and the clinical therapeutic effects of symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy. A retrospective analysis was performed in 18 patients (10 males and 8 females, aged 30-62 years with an average age of 45.3 years) with cervical vertebral hemangioma associated with cervical spondylotic myelopathy between January 2006 and September 2008. The disease duration was 10-26 months (mean, 15.6 months). All patients had single vertebral hemangioma, including 2 cases at C3, 3 cases at C4, 5 cases at C5, 5 cases at C6, and 3 cases at C7. The X-ray films showed a typical "palisade" change. According to the clinical and imaging features, there were 13 cases of type II and 5 cases of type IV of cervical hemangioma. The standard anterior cervical decompression and fusion with internal fixation were performed and then percutaneous vertebroplasty (PVP) was used. The cervical X-ray films were taken to observe bone cement distribution and the internal fixation after operation. The recovery of neurological function and the neck pain relief were measured by Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) score. All operations were successful with no spinal cord and nerves injury, and the incisions healed well. Anterior bone cement leakage occurred in 2 cases without any symptoms. All cases were followed up 24-28 months (mean, 26 months) and the symptoms were improved at different degrees without fracture and collapse of vertebra or recurrence of hemangioma. During the follow-up, there was no implant loosening, breakage and displacement, and the mean fusion time was 4 months (range, 3-4.5 months). The JOA score and VAS score had a significant recovery at 3 months and at last follow-up when compared with preoperative values (P < 0.05). Based on JOA score at last follow-up, the results were excellent in 9 cases, good in 6 cases, fair in 2 cases, and poor in 1 case. The anterior cervical decompression and fusion with internal fixation combined with PVP treatment is one of the ideal ways to treat symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy, which could completely decompress the spinal cord and effectively alleviate the clinical symptoms caused by vertebral hemangioma.

Background Cancers that metastasize to the spine and primary cancers such as multiple myeloma can result in vertebral compression fractures or instability. Conservative strategies, including bed rest, bracing, and analgesic use, can be ineffective, resulting in continued pain and progressive functional disability limiting mobility and self-care. Surgery is not usually an option for cancer patients in advanced disease states because of their poor medical health or functional status and limited life expectancy. The objectives of this review were to evaluate the effectiveness and safety of percutaneous image-guided vertebral augmentation techniques, vertebroplasty and kyphoplasty, for palliation of cancer-related vertebral compression fractures. Methods We performed a systematic literature search for studies on vertebral augmentation of cancer-related vertebral compression fractures published from January 1, 2000, to October 2014; abstracts were screened by a single reviewer. For those studies meeting the eligibility criteria, full-text articles were obtained. Owing to the heterogeneity of the clinical reports, we performed a narrative synthesis based on an analytical framework constructed for the type of cancer-related vertebral fractures and the diversity of the vertebral augmentation interventions. Results The evidence review identified 3,391 citations, of which 111 clinical reports (4,235 patients) evaluated the effectiveness of vertebroplasty (78 reports, 2,545 patients) or kyphoplasty (33 reports, 1,690 patients) for patients with mixed primary spinal metastatic cancers, multiple myeloma, or hemangiomas. Overall the mean pain intensity scores often reported within 48 hours of vertebral augmentation (kyphoplasty or vertebroplasty), were significantly reduced. Analgesic use, although variably reported, usually involved parallel decreases, particularly in opioids, and mean pain-related disability scores were also significantly improved. In a randomized controlled trial comparing kyphoplasty with usual care, improvements in pain scores, pain-related disability, and health-related quality of life were significantly better in the kyphoplasty group than in the usual care group. Bone cement leakage, mostly asymptomatic, was commonly reported after vertebroplasty and kyphoplasty. Major adverse events, however, were uncommon. Conclusions Both vertebroplasty and kyphoplasty significantly and rapidly reduced pain intensity in cancer patients with vertebral compression fractures. The procedures also significantly decreased the need for opioid pain medication, and functional disabilities related to back and neck pain. Pain palliative improvements and low complication rates were consistent across the various cancer populations and vertebral fractures that were investigated. PMID:27298655

The authors present an extremely rare case of an aggressive and progressive vertebral capillary hemangioma of the lumbar spine secondary to a trauma. A 40-year-old man who complained of back and leg pain due to a hemangioma of L1 that had begun a year after the fracture of the same vertebra was subsequently operated on. Due to the profuse bleeding, only a subtotal removal was possible. Histopathological diagnosis of the lesion revealed a capillary hemangioma. Postoperative control MRI taken at eight months showed that the lesion and destruction of the L1 vertebra were progressive. A second embolization procedure was performed and this time the hemangioma was totally removed via an anterior approach and corpectomy. Fusion was achieved by Th12-L2 graft and plaque. In the fourteenth year of follow-up, he was symptom-free and radiologically clear of this lesion. We propose that progressive hemangioma is extremely rare and that its cure is possible by total surgical removal of the lesion. This case is the second extradural capillary hemangioma secondary to spinal trauma ever to have been documented in English literature. The emergence of a hemangioma in a fractured vertebra suggests that its pathogenesis can be related to the deviation of the angiogenetic pathways from the normal healing process. PMID:28713608

Vertebral hemangioma (VH) is an exceedingly rare neoplasm in pediatric population with less than 10 cases reported in the literature. It is usually asymptomatic in adults and diagnosed incidentally at radiographic investigations of other medical conditions. In this report, we describe two children who presented to our institution with severe back pain and were diagnosed with VH. Case 1 was an 8-year-old male with a pain score of 10 out of 10 at presentation. Clinical investigations eliminated the possibility of a neoplasm or infectious process and MRI findings were highly suggestive of an aggressive vertebral hemangioma. Case 2 was a 17-year-old female who presented with back pain radiating to shoulders. Her pain score was 4 out of 10 and she was diagnosed with vertebral hemangioma due to the specific findings on MRI studies. Both patients received propranolol with a dose of 20 and 40 mg per day, respectively. They were free of pain at 2 months follow-up. There are different invasive treatment modalities for the management of VH, including vertebroplasty, kyphoplasty, radiotherapy, alcohol injection, embolization, and surgery. These methods have been used in adult patients for several years, but each of them has potential risks which make these options unsuitable for children. Propranolol is a beta blocker which is safely used in the management of infantile hemangiomas. This is the first report demonstrating its efficacy in symptomatic treatment of childhood VH. The lesions did not show any regression, but the pain relief obtained was very significant under propranolol therapy.

Vertebral hemangiomas (VHs) are a frequent and often incidental finding on computed tomography (CT) and magnetic resonance (MR) imaging of the spine. When their imaging appearance is "typical" (coarsened vertical trabeculae on radiographic and CT images, hyperintensity on T1- and T2-weighted MR images), the radiological diagnosis is straightforward. Nonetheless, VHs might also display an "atypical" appearance on MR imaging because of their histological features (amount of fat, vessels, and interstitial edema). Although the majority of VHs are asymptomatic and quiescent lesions, they can exhibit active behaviors, including growing quickly, extending beyond the vertebral body, and invading the paravertebral and/or epidural space with possible compression of the spinal cord and/or nerve roots ("aggressive" VHs). These "atypical" and "aggressive" VHs are a radiological challenge since they can mimic primary bony malignancies or metastases. CT plays a central role in the workup of atypical VHs, being the most appropriate imaging modality to highlight the polka-dot appearance that is representative of them. When aggressive VHs are suspected, both CT and MR are needed. MR is the best imaging modality to characterize the epidural and/or soft-tissue component, helping in the differential diagnosis. Angiography is a useful imaging adjunct for evaluating and even treating aggressive VHs. The primary objectives of this review article are to summarize the clinical, pathological, and imaging features of VHs, as well as the treatment options, and to provide a practical guide for the differential diagnosis, focusing on the rationale assessment of the findings from radiography, CT, and MR imaging.

Vertebral hemangiomas (VHs) are common lesions in the adult population. They are usually asymptomatic and found incidentally on radiological imaging. New-onset back pain followed by subacute progression of thoracal myelopathy is the most common presentation in patients with neurological deficit. Differential diagnoses would include metastasis, multiple myeloma, lymphoma, Paget disease, osseous tumors such as Ewing sarcoma or hemangioblastoma and blood dyscrasia. We present a 41 year-old-male patient with thoracal VH causing myelopathy that completely improved after rehabilitation program with embolization and vertebroplasty procedures.

Capillary hemangiomas are benign vascular neoplasms. When associated with the spine, these growths frequently involve the vertebral body, but rarely have they been reported to occur as intradural lesions, while even more rarely occurring in a true intramedullary location. We report a rare case of an intramedullary capillary hemangioma of the thoracic spinal cord and a review of the literature. PMID:21139881

To describe the clinical, diagnostic and therapeutic features of this angiomatous neurocutaneous syndrome, which is the most frequent one, and to report a personal series of 41 patients. Forty one patients--31 females and 10 males--were studied during childhood and then, several patients were followed during many years, which allowed us to learn about the evolution of the abnormalities. The cutaneous lesions were classified as hemangiomas in 30 patients (73%) and as vascular malformations in 11 patients (27%). A cerebellar anomaly (unilateral hemispheric hypoplasia and Dandy-Walker malformation) was seen in 13 patients (31.5%) cerebral cortical dysplasia in 4 patients (10%), aortic arch coarctation in 6 patients (15%), and congenital cardiopathy in 5 patients (12%). The most frequent abnormalities were intracranial and/or extracranial vascular malformations. Persistence of the trigeminal artery was observed in 7 patients (17%), absence or severe hypoplasia of an internal carotid artery in 13 patients (32%), absence of a vertebral artery in 7 patients (17%), hypoplasia of intracranial arteries in 6 patients (15%) and aneurysmal enlargement of carotid or vertebral arteries in 5 patients (12%). Also were observed 4 patients (10%) with intracranial hemangioma, 2 (5%) with hemangioma in mediastinum, and 3 (7.5%) with intestinal hemangioma, all of which disappeared during the first years of life. Aneurysmal enlargement of the carotid and vertebral arteries and intracranial branches also disappeared after a process of progressive narrowing of the arterial lumen that caused complete obstruction of these arteries. At the same time the cutaneous hemangioma regressed. During this process, collateral vascularization through branches of the external carotid artery and of the non-affected branches of the contralateral intracranial arteries developed. This neurocutaneous syndrome is the most frequent one and it is associated with several types of vascular and non-vascular abnormalities which can involve any organ of the body. Internal and external hemangiomas and hemangiomatous lesions progress and tend to regress concomitantly.

Hemangioma is the most common primary tumor of the spine. Pregnancy is a risk factor increasing the possibility of disclosure or exacerbation of symptoms of spinal hemangioma. This paper presents a case of 32-year-old woman with hemangioma of Th6 vertebrae, which was revealed by paresis of the lower limbs and sphincters dysfunction at 34 weeks gestation. Pregnancy has ended with a cesarean section. Then posterolateral thoracotomy and removal of hemangioma were performed. Spinal cord was decompressed and stabilization of the spine with metal implants was carried out. Histological examination discovered cavernous hemangioma weaving. The patient is followed up in the outpatient clinic. Despite the improvement of neurological status--enhancement of the sensory function and development of bladder and rectal sphincter automatism--she did not regain the ability to walk alone.

Cavernous hemangioma is an encapsulated mass of dilated, endothelial lined vascular channels filled with slowly flowing blood. Cavernous hemangioma of the spleen is a rare condition with less than 100 reports so far. Hemangioma of the vertebral is a benign vascular legion around one or two vertebrae. These are usually asymptomatic and discovered incidentally. In this study we reported an extreme rare case of splenic hemangioma coexistence with vascular malformation of the vertebrae. To our knowledge this is the first report of coexistence of splenic hemangioma and hemangioma of the vertebra. A 20-year-old iranian male with splenomegaly, abdominal pain, diarrhea and pancytopenia who was first highly suspicious for malignancy referred to our center for evaluation of the diagnostic workup. After full examination we detected a very rare case with a giant, solitary cavernous hemangioma of the spleen and multiple hemangiomas in his vertebrae. Histopathology of the spleen showed a large cavernous hemangioma occupying almost the entire spleen with large areas of infarction necrosis with multiple hemangiomas of the vertebrae. It is extremely rare to have a splenic hemangioma concurrent with vertebra hemangioma and this is clinically very important to consider splenic hemangioma in differential diagnosis of splenomegaly for a better therapeutic management in related patients.

Spinal intramedullary arteriovenous malformations are uncommon and a challenging type of neurosurgical entities. They are rarely located to cervical segment. On the other hand, although hemangiomas are relatively common bone tumors, cervical involvement is again rare and clinically significant ones are infrequent. A 14 year-old-male patient referred to an academic tertiary care unit and presented with neck pain and left hand weakness. Neurological examination revealed motor strength deficit at intrinsic muscles and hyperesthesia at the left hand. Furthermore the pathological reflexes were positive on the left hand side. Imaging studies showed compression fracture, lytic changes resembling a hemangioma at C7 vertebra, and also an intramedullary vascular pathology at C5-6 level which was shown to be an intradural-intramedullary arteriovenous malformation (AVM) on digital subtraction angiography. Based on neurological and radiological findings, the decision was to treat the patient. After embolization of the AVM, the neurological condition of the patient deteriorated and immediate MRI scan of the cervical spine revealed edema of the spinal cord at the C5-6 level. Thus an emergent surgery was performed and C5-6-7 laminectomies with C5-T2 posterior fixation and arthrodesis were implemented. A second stage operation was carried out as C7 corpectomy with a distractable titanium cage 2 weeks after initial surgery. A follow-up evaluation at five years revealed 4/5 motor strength on his left intrinsic hand muscles and mild hyperactive deep tendon reflexes. Imaging studies at the postoperative period showed stable placement of the construct and no evidence of contrast enhancement at the C5-6 level inside the spinal cord. A rare case of multiple pathologies affecting the cervical spine, coincidentally diagnosed after a pathological fracture during a bicycle accident as vertebral hemangioma and intradural-intramedullary AVM that was successfully treated with early detection, have been presented. One should assess such patients under multidisciplinary fashion and treat on a case-by-case basis for achieving the best results in patient care.

Vertebral hemangiomas (VHs) are the most common form of benign tumors in the spine. The aim of this research was to study the prevalence of VHs in the human population, their distribution along the spine and their location in the vertebral body. The presence of VHs was assessed in full spine CT scans of 196 adults. Demographic data were gathered from medical records. VHs were present in 26.0% of the individuals studied, a rate significantly higher (χ2=43.338, p<0.001) than the prevalence reported in the literature (10.7%). Multiple VHs (≥2) appeared in 7.2% of the population studied. VHs prevalence is sex-independent, appearing in 28.6% of females and 23.5% of males (χ2=0.663, p=0.416); and age-dependent: the mean age of affected individuals (65.8 years) was significantly higher (p<0.001) than unaffected individuals (56.2 years). VH size was also age-dependent (p=0.023). No vertebra was significantly more prone to be affected by a hemangioma. T11 and T12 show the highest prevalence of VHs (3.57% of vertebrae affected). VHs were found in similar percentages in the anterior and posterior parts of the vertebral body (52.8 vs. 47.2%, respectively); and at its center and periphery (50.1 and 49.9%, respectively). VHs usually appeared at mid-height of the vertebral body or slightly higher. The reported prevalence of VHs is dependent on the demographic structure of the population studied, the size of the VHs and the method used to identify them. Overall, the phenomenon is more frequent than usually reported. VHs may appear at all vertebral levels and in all areas of the vertebral body.

Aggressive vertebral hemangiomas are rare tumors of the spine. The treatment management strategy usually consists of vertebroplasty, radiation therapy or in rare cases of surgical strategy. We present a case of a bulging sacral S1-S2 hemangioma in the spinal canal that could not be managed in the usual manner. Here, we demonstrate the usefulness of radiofrequency ablation technique as an alternative treatment as well as robotic assistance for optimal placement of the ablation probe within the lesion.

To investigate the surgical results of one-stage total en bloc spondylectomy (TES) and reconstruction via a single posterior approach for thoracic symptomatic vertebral hemangioma associated with spinal cord dysfunction and evaluate its curative effect. A total of 9 patients treated with one-stage TES (7 cases) and total vertebrectomy (2 cases) by posterior approach from March 2006 to January 2010 were retrospectively reviewed. The cases included 2 males and 7 females with a median age of 33.6 years (range 14 to 77 years), and with 1 case of Grade A, 3 cases of Grade B, 3 cases of Grade C, 2 cases of Grade D according to Frankel grade system. All patients suffered from moderate to severe pain and neurological deficit with an average symptom duration of 14.4 months (range 3 - 24 months) MRI revealed severe spinal cord compression. The spinal reconstruction was obtained by titanium mesh filled with autograft and posterior internal fixation with rod-screw system. The operation time was 210 minutes on average (180 - 270 minutes) and the average blood loss was 1800 ml (1000 - 5000 ml). The follow-up period lasted from 18 months to 5 years. All cases with preoperative pain relieved after operation. The visual analogue scale pain scores decreased to 1.1 from 8.3 at 3 months after surgery. No disruption of dural mater, cerebrospinal fluid leakage, iatrogenic spinal cord injury and major vessel damage occurred. Up to now, there was no local recurrence in all cases. Significant neurological function improvement was achieved in all patients with one to three grades in Frankel grade system. Fusion of the autograft was well achieved and no internal fixation failure in all patients. One-stage TES and spine reconstruction by a single posterior approach is feasible, safe and effective to this disease. It is favourable in decreasing the hemangioma recurrence and improvement of the neurological function.

Symptoms may vary from simple vertebral pain to progressive neurologic deficit because of cervical vertebral hemangioma associated with adjacent cervical spondylotic myelopathy (CVHAWACSM). Often resistant to conservative medical treatment, surgery has been the treatment of choice for these patients, but the optimal surgical strategy for CVHAWACSM has not been defined. This study aimed to investigate the methods and efficacy in the treatment of CVHAWACSM. Retrospective review of patients enrolled in prospective randomized trial. Procedure was performed in 18 patients (11 men and 7 women) with CVHAWACSM, who were enrolled between January 2006 and September 2011. Radiographic examinations were carried out to assess total filling of polymethylmethacrylate in the vertebral body, fusion rates, implant failure, and general complications. The recovery of neurologic function and neck and shoulder pain relief were measured based on the Japanese Orthopedic Association (JOA) and the visual analog scale (VAS) scores. Eighteen patients had single vertebral hemangioma, including one case at C₃, three at C₄, six at C₅, five at C₆, and three at C₇. The X-ray films showed a typical "palisade" change. According to the clinical and imaging features, there were 12 cases of Type II and 6 of Type IV cervical hemangioma. Standard anterior cervical decompression and fusion with a stand-alone polyetheretherketone cage (filled with autologous cancellous iliac bone) was performed, followed by vertebroplasty. Clinical and radiologic follow-ups were performed. The mean follow-up was 24.1 months, with a range of 18 to 36 months. The symptoms of all 18 patients were improved, by varying degrees, and the lesion vertebra did not show anterior bone cement leakage or injuries in the spinal cord and nerves. The forming vertebra did not show fracture or collapse, and there was no recurrence of the hemangioma. During the follow-up, there was no implant loosening, displacement, or breakage. The JOA and the VAS scores were significantly recovered at 3 months after the operation and in the last follow-up, compared with the preoperative level (p<.05). The JOA scores in the last follow-up showed 13 excellent, 4 good, 1 fair, and 0 poor cases. This procedure seems to be a safe efficient method to treat symptomatic CVHAWACSM. It seems to serve the purpose of providing vertebral augmentation, cord decompression, and rigid fusion at the same sitting. Although the present outcomes are promising, long-term follow-up studies with larger patient numbers are required to confirm this effect. Copyright © 2013 Elsevier Inc. All rights reserved.

Pure epidural cavernous hemangioma of the spine without vertebral involvement is rare. Due to the slow growth of this lesion, the most common symptoms are chronic pain, myelopathy, and radiculopathy. In our case, the patient complained of an acute onset sensory deficit of the C4 dermatome. An MRI revealed an epidural mass with an acute hematoma. Here, we report a case of a pure epidural cavernous hemangioma that presented with acute neurologic symptoms caused by intralesional hemorrhage and an acute epidural hematoma, which were demonstrated on the patient's MRI.

Ga-PSMA PET/CT was performed in a 68-year-old man to evaluate recurrent prostate cancer due to elevated serum prostate-specific antigen level. Images showed a focal uptake in the prostatic gland, suggesting local relapse, and an intense uptake in the 12th thoracic vertebra, with no morphological abnormalities in CT slices. In order to confirm extraprostatic disease and before radiotherapy planning, a full-spine MRI was performed, resulting with the morphological pattern of a vertebral hemangioma. Hystological analysis confirmed the local relapse in the prostate. No radiotherapy treatment was given to the vertebra, and after 1 year of follow-up without systemic treatment, prostate-specific antigen is still undetectable.

Hemangiomas are benign vascular neoplasms characterized by an abnormal proliferation of blood vessels. They may occur in any vascularized tissue including skin, subcutaneous tissue, muscle, and bone. Intraosseous hemangiomas are uncommon, constituting less than 1% of all osseous tumors. The most frequent sites are the calvaria and the vertebral column. Involvement of the facial bones is rare and occurs most commonly in the maxilla, mandible, and nasal bones. In literature, only 20 cases of zygomatic involvement have been reported. We report a case of an intraosseous hemangioma of the zygoma with the history and physical findings of slowly growing, bony, hard tumor causing facial and ocular deformity. The typical clinicopathologic and radiologic findings helped to set up the correct diagnosis. Early recognition and excision are recommended to preserve facial contour. Operative blood loss is minimal, and there is no need for preoperative angiography.

Hemangiomas are benign dysplasias or vascular tumors consisting of vascular spaces lined with endothelium. Nowadays, radiotherapy for vertebral hemangiomas (VHs) is widely accepted as primary treatment for painful lesions. Nevertheless, the role of surgery is still unclear. The purpose of this study is to propose a novel algorithm of treatment about VHs. This is a case report of an extensive VH and a review of the literature. A case of vertebral fracture during radiotherapy at a total dose of 30 Gy given in 10 fractions (treatment time 2 weeks) using a linear accelerator at 15 MV high-energy photons for extensive VH is reported. Using PubMed database, a review of the literature is done. The authors have no study funding sources. The authors have no conflicting financial interests. In the literature, good results in terms of pain and neurological deficits are reported. No cases of vertebral fractures are described. However, there is no consensus regarding the treatment for VHs. Radiotherapy is widely utilized in VHs determining pain. Surgery for VHs determining neurological deficit is also widely accepted. Perhaps, regarding the width of the lesion, no indications are given. We consider it important to make an evaluation before initiating the treatment for the risk of pathologic vertebral fracture, since in radiotherapy, there is no convention regarding structural changes determined in VHs. We propose a new algorithm of treatment. We recommend radiotherapy only for small lesions in which vertebral stability is not concerned. Kyphoplasty can be proposed for asymptomatic patients in which VHs are small and in patients affected by VHs determining pain without spinal canal invasion in which the VH is small. In patients affected by pain without spinal canal invasion but in which the VH is wide or presented with spinal canal invasion and in patients affected by neurological deficits, we propose surgery.

Capillary hemangiomas are common benign vascular tumors on skin and soft tissues, but developing as an intradural and extramedullary (IDEM) tumor in spine is extremely rare. In this report, we present IDEM tumor compressing thoracic cord in T2–3 level with extensive arachnoiditis below the tumor level in a 60-year-old man. The lesion was removed and histological diagnosis was capillary hemangioma. Prompt diagnosis and resection are important to avoid neurological deterioration from acute hemorrhagic condition. Simultaneous arachnoiditis may be originated from old subarachnoid hemorrhage associated tumor before diagnosis, and we suggest it as a helpful diagnostic feature to suspect vascular tumors such as capillary hemangioma.

An epithelioid hemangioma involving three contiguous bones in continuity has, to the best of our knowledge, not been reported in the literature. A case of a 48-year-old man presented with radiating pain to the lower thoracic region for two years. A radiograph and CT scan revealed both permeative osteolytic and multiple trabeculated lesions involving the left posterior part of the 10th rib as well as the 9th and 10th vertebral bodies in continuity and was misled as a malignant or infectious lesion. The histopathology and immuno-histochemistry of the lesion confirmed the diagnosis of an epithelioid hemangioma. The lesion was still stable as of three years after surgery. PMID:21076597
[Spasmodic torticollis and vertebral hemangioma].
Durán, E; Chacón, J R
Spasmodic torticollis in young patients should give rise to a clinical suspicion that this is secondary to another primary disorder. Therefore a series of diagnostic tests should be carried out before it is labelled as idiopathic. The patient was a thirty year old man who had had difficulty in writing with his right hand since childhood. At the age of 20 years he was diagnosed as having writer's cramp and idiopathic spasmodic torticollis. On general physical examination no abnormalities were found. On neurological examination he had: absence of reflexes of both arms, limited but painless rotation of the neck towards the left and hypertrophy of the left trapezius muscle. Laboratory, neurophysiological and neuroimaging investigations seeking a secondary cause for the torticollis were all normal. There were no Keyser-Fleischer rings. Chest X-ray showed, dorsal scoliosis with convexity to the left. CAT and MR of the spine showed a hemangioma in the body of T1. On arteriography of the supra-aortic and vertebral trunks a hemangioma was found at T1 which received contrast material via a branch of the right thyro-bi-cervico-scapular trunk. Various treatments were tried (diazepam, Botox, Dysport, tetrabenazine, baclofen, etc.) with no improvement. A definite diagnosis of secondary torticollis could not be made since the hemangioma was supplied by a very narrow vascular pedicle, so embolization was contraindicated. Cervical spinal cord alterations may cause focal dystonia due to increased excitability of the spinal motor neurone, due to dysfunction of the disinhibitory descending reciprocal paths.
Sacroplasty for symptomatic sacral hemangioma: a novel treatment approach. A case report.

Painful vertebral body hemangiomas have been successfully treated with vertebroplasty and kyphoplasty. Sacral hemangiomas are uncommon and as such painful sacral hemangiomas are rare entities. We report what we believe is only the second successful treatment of a painful sacral hemangioma with CT-guided sacroplasty. A 56-year-old woman with a history of right-sided total hip arthroplasty and lipoma excision presented to her orthopedic surgeon with persistent right-sided low back pain which radiated into her buttock and right groin and hindered her ability to walk and perform her activities of daily living. MRIs of the thoracic spine, lumbar spine and pelvis showed numerous lesions with imaging characteristics consistent with multiple hemangiomas including a 2.2×2.1 cm lesion involving the right sacrum adjacent to the right S1 neural foramen. Conservative measures including rest, physical therapy, oral analgesics and right-sided sacroiliac joint steroid injection did not provide significant relief. Given her lack of improvement and the fact that her pain localized to the right sacrum, the patient underwent CT-guided sacroplasty for treatment of a painful right sacral hemangioma. Under CT fluoroscopic guidance, a 10 gauge introducer needle was advanced through the soft tissues of the back to the margin of the lesion. Biopsy was then performed and after appropriate preparation, cement was then introduced through the needle using a separate cement filler cannula. Appropriate filling of the right sacral hemangioma was visualized using intermittent CT fluoroscopy. After injection of approximately 2.5 cc of cement, it was felt that there was near complete filling of the right sacral hemangioma. With satisfactory achievement of cement filling, the procedure was terminated. Pathology from biopsy taken at the time of the procedure was consistent with hemangioma. Image-guided sacroplasty with well-defined endpoints is an effective, minimally invasive and safe procedure. Patients with painful sacral hemangiomas can be treated with this technique with no significant complications.

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim. A biopsy was performed by applying a direct incision after local anesthesia. Eventually, intraosseous hemangioma was diagnosed histologically. To fully resect the mass, the orbital floor and zygoma were exposed through a subciliary incision under general anesthesia, and then the tumor was completely eliminated. Bony defect was reconstructed by performing a seventh rib bone graft. Follow-up observation has so far been conducted for 10 months after surgery without recurrence or symptoms.

A case report and literature review. We present the fourth case of a spinal epidural capillary hemangioma with a dumbbell-shaped appearance in the magnetic resonance image reported in the literature and the second presented as a lung mass. Hemangiomas are congenital vascular malformations that pathologists frequently consider to be hamartomatous malformations. Hemangiomas of the spine are usually lesions of the vertebral bodies, but they can sit in other locations such as the intramedullary or epidural space. Purely epidural hemangiomas are rare and most of them are of cavernous type. We present a 67-year-old female with a thoracic dumbbell-shaped capillary hemangioma with both foraminal and intrathoracic extensions, whose presentation was pleural effusion associated with mediastinal mass suggestive of pulmonary neoplasia. Surgical treatment consisted of total removal en bloc of the lesion. Microscopic evaluation showed a fibrofatty tissue with a proliferation of vascular structures that were generally of a small size, with areas of myxoid appearance. To date, there have been 8 epidural capillary hemangiomas of the thoracic and lumbar spine reported in the literature, and only 3 of them were dumbbell-shaped with extraforaminal extension. It is important to consider the diagnosis of hemangiomas in the differential diagnosis of epidural lesions with dumbbell-shaped appearance in the magnetic resonance image, especially at the thoracic level. It is a benign and potentially curable disease and the most appropriate surgical treatment is en bloc resection of the entire lesion. They are usually presented as a progressive myelopathy, so early treatment may prevent permanent neurological deficits. 5.

We present two cases of angio-proliferative tumors that were misdiagnosed and treated as typical hemangiomas with epidural expansion. Two middle-aged women presented with symptoms and radiological signs characteristic for aggressive hemangioma with epidural expansion. In the first case preoperative embolization and decompressive surgery with open transpedicular vertebroplasty was performed. Within less than a year, epidural recurrence of the tumor prompted for radical excision and corpectomy. The diagnosis after the histological studies and the further clinical evolution was metastasizing leiomyomatosis. No further recurrence occured during the next 6 years. In the second case percutaneous vertebroplasty was performed and complicated by epidural polymethyl-methacrylcate (PMMA) leakage, requiring urgent decompressive surgery. Histological study of the lesion raised the possibility of myopericytoma. This was confirmed 16 months later when complete vertebrectomy was performed due to severe epidural propagation of the recurring tumor. No further recurrence occurred in next the two years. Rare angio-proliferative tumors, like benign metastasizing leiomyoma and myopericytoma radiologically may resemble aggressive vertebral hemangiomas of the spine. Unlike hemangiomas, such tumors require radical removal due to their likely recurrence. As imaging studies may not be able to completely exclude such pathologies, bone biopsy and thorough histopathological studies are warranted prior to the therapeutic decision.

A 24-year-old male soldier on limited-duty status was referred to physical therapy by his primary care physician for a 2-year history of insidious-onset and slowly progressive low back pain. Lumbar radiographs were noncontributory. Shortly after initiating rehabilitation, the patient underwent magnetic resonance imaging that was previously ordered by his primary care physician. Radiology identified a complex mass and cortical fracturing within the L1 vertebral body, and subsequent computed tomography imaging demonstrated mixed sclerotic and lytic foci at L1. Biopsy later confirmed an epithelioid hemangioma. J Orthop Sports Phys Ther 2017;47(5):367. doi:10.2519/jospt.2017.6689.

Vertebral hemangioma (VH) is virtually vascular malformation, which is usually asymptomatic. Only 3.7 % of VH may become active and symptomatic, and 1 % may invade the spinal canal and/or paravertebral space. Treatment protocols for active or aggressive VHs are still in controversy. Reported treatments include radiotherapy, vertebroplasty, direct alcohol injection, embolization, surgery and a combination of these modalities. A 41-year-old lady was presented with 18 month history of intermittent back pain. CT revealed T5 osteolytic lesion with epidural and paravertebral extension. The first CT guided biopsy yielded little information. Histopathological diagnosis of the second biopsy was VH. Vertebroplasty, posterior decompression and fixation were performed followed by postoperative radiotherapy. Her symptoms were resolved immediately after the operation. At 12 months follow-up, no recurrence was detected by CT with contrast enhancement. Surgical decompression, vertebroplasty and fixation are safe and effective for aggressive VH. More attention is needed in determining the algorithm for the diagnosis and treatment of aggressive VH.

Mechanisms of angiogenesis regulate multiple sclerosis (MS) lesions' evolution, displaying both neuroprotective and harmful effects. Factors traditionally considered as purely angiogenic, like vascular endothelial growth factor (VEGF), exert complex heterogenous actions on both neural and vascular malformation-derived tissues. Aim of this retrospective study was to examine, for the first time, potential associations between the presence of common vascular malformations, like vertebral hemangiomas (VHs), and several clinico-radiological MS parameters. 236 MS patients who were followed in our Outpatient Clinic were recruited in this study. Outcome measures concerned demographics, disease-derived variables, and MS-lesions' distribution in VHs - positive and negative patients. All data were collected retrospectively. Potential correlations were assessed with univariate statistical analyses (p = 0.05), followed by multivariate regression models, for purposes of confounder-effects elimination. VH presence showed significant negative correlations with presence of MS lesions in the thoracic (p = 0.005 for thoracic VHs), but not the cervical cord. Trends towards negative associations of VH presence with subtentorial MS lesions and positive family history for MS were also observed. Our observations suggest that VH presence may reduce the risk of thoracic demyelinating lesions in MS patients. They could be explained as part of a multifaceted angiogenic process, concomitantly enhancing neural repair and abnormal hemangioma vascularization.

Cavernous hemangioma of the skull is a rare pathological diagnosis, accounting for 0.2% of bone tumors and 7% of skull tumors. Usually calvarial bone cavernous hemangioma are associated with a benign clinical course and, despite their enlargement and subsequent erosion of the surrounding bone, the inner table of the skull remains intact and the lesion is completely extracranial. The authors present the unique case of a huge left frontal bone cavernous malformation with intradural extension and brain compression determining a right hemiparesis. Calvarial cavernous hemangiomas are benign tumors. They arise from vessels in the diploic space and tend to involve the outer table of the skull with relative sparing of the inner table. More extensive involvement of the inner table and extradural space is very unusual and few cases are reported in literature.

Introduction Cavernous hemangioma of the skull is a rare pathological diagnosis, accounting for 0.2% of bone tumors and 7% of skull tumors. Usually calvarial bone cavernous hemangioma are associated with a benign clinical course and, despite their enlargement and subsequent erosion of the surrounding bone, the inner table of the skull remains intact and the lesion is completely extracranial. Presentation of a case The authors present the unique case of a huge left frontal bone cavernous malformation with intradural extension and brain compression determining a right hemiparesis. Discussion Calvarial cavernous hemangiomas are benign tumors. They arise from vessels in the diploic space and tend to involve the outer table of the skull with relative sparing of the inner table. More extensive involvement of the inner table and extradural space is very unusual and few cases are reported in literature. To the best of our knowledge, intradural invasion of calvarial hemangioma has not been previously reported. Conclusion Our case highlights the possibility of an aggressive course of this rare benign pathology. PMID:27061482

Epithelioid hemangioma (EH) of bone is a benign vascular tumor that can be locally aggressive. It rarely arises in the spine, and the optimum management of EH of the vertebrae is not well delineated. The report describes our experience treating six patients with EH of the spine in an effort to document the treatment of the rare spinal presentation. This study is designed as a retrospective cohort study. A continuous series of patients with the diagnosis of EH of the spine who presented at our institution. The clinical and radiographic follow-up of the patient population is documented. The Bone Sarcoma Registry at our institution was used to obtain a list of all patients diagnosed with EH of the spine. Medical records, radiographs, and pathology reports were retrospectively reviewed in all cases. Only biopsy-proven cases were included. The six patients included five men and one woman who ranged in age from 20 to 58 years (with an average age of 40 years). The follow-up available for all six patients ranged from 6 to 115 (average 46.8) months. All patients presented with lytic vertebral body lesions. Five patients presented with pain secondary to their tumor, and the tumor in the sixth patient was found incidentally during the workup for a herniated disc. Three patients required surgical management for instability secondary to the destructive nature of their tumors, and two other patients required emergent decompression secondary to spinal cord compression by the tumor. The sixth patient was treated expectantly after biopsy confirmation. Three patients received postoperative radiation therapy as gross tumor remained after surgery. Three patients had gross total resections and did not receive postoperative radiation. Preoperative embolization was used in four patients. One patient continued to have back pain after surgery and radiation and another continued to have ataxia after surgery and radiation. No tumor locally recurred or progressed. Our data suggest that EH of the spine can be locally aggressive and lead to instability and cord compression. Surgery is required in such instances; however, observation should be considered in patients without instability or cord compression. Copyright © 2013 Elsevier Inc. All rights reserved.

Purpose: An evaluation of dose-response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) weremore » 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake before radiotherapy.« less

A case report. To describe the presentation of compressive paraparesis as a result of thoracic rib hemangioma in a young adult and its nonsurgical management. Hemangiomas are rare bone tumors and those arising from rib are rarer. Only about 50 such cases have been reported in literature so far. A 21-year-old male student, presented to us with a 6-week history of progressive weakness in both lower limbs and loss of bowel bladder control. Patient gave history of being operated for left periscapular tumor treated with wide excision and proven with biopsy to be a hemangioendothelioma (benign but locally aggressive hemangioma variant) a year ago. New radiograph of the chest showed an expansile lesion of left fifth rib and magnetic resonance image showed a tumor of left dorsal thoracic wall with AV malformation causing compressive thoracic myelopathy at T5 level vertebrae. We planned for immediate decompression surgery for spine along with excision of tumor with the help of a thoracic surgeon. However, on preoperative digital subtraction angiography, the tumor was found to be highly vascular with high risk of intraoperative bleeding and morbidity. So, the plan was revised and the patient underwent digital subtraction angiography, followed by embolization by an expert interventional neurosurgeon. The patient showed signs of recovery within a week. Lower limb power improved from grade 2 to 3/5 to grade 4 to 4+/5. The patient became ambulatory with single stick at 3-month follow-up; he was a nonwalker to start with. At 2 years plus follow-up, the patient fully recovered and walks without stick. This unique case brings to light the dilemma a spine surgeon sometimes faces. A case that warranted immediate surgical intervention based on clinical findings was treated with interventional fibrin glue embolizations with excellent results. N/A.

A case report and a discussion of recent published data. To highlight the importance of vertebral hemangioma (VH) as a differential diagnosis in the evaluation of locally aggressive spinal lesions. VH commonly occur as incidental findings, however, locally aggressive VH have been described. Difficulties in diagnosing these lesions are well reported and relate to changes in fat content causing uncharacteristic appearances on imaging. The management options for these lesions include a combination of observation, embolization, sclerotherapy, surgical decompression, or stabilization and radiotherapy. A 45-year-old patient who was previously well presented with back pain and rapidly progressive paraparesis. Imaging confirmed the presence of an extensive lesion centered within the right T3 vertebral pedicle with intrusion into the spinal canal. Urgent surgical decompression was undertaken and was complicated by extensive intraoperative hemorrhage requiring massive transfusion. Histologically, the lesion was shown to be a cavernous VH with no evidence of malignancy. Following radiation oncology review, he was offered adjuvant radiotherapy to minimize the risks of recurrence. He achieved a near full neurologic recovery within 2 weeks and had a full recovery by 12 months. VH should be considered in the evaluation of locally aggressive spinal lesions. Angiography is a useful adjunct in the evaluation of these lesions, both as a diagnostic and therapeutic tool. After diagnosed correctly a wide range of treatment options exist that may prevent the patient from undergoing major surgical resection and reconstruction procedures, which may be associated with high rates of morbidity.

Epithelioid hemangioendothelioma (EHE) has been described as a rare vascular bone lesion with histological features between hemangioma and high-grade angiosarcoma. Spinal EHE is a quite rare disease with few case reports and series reported in the literature. The tumor cells are positive for vimentin, CD31and CD34, factor VIII related antigen, ERG, and FLI1. Radiological features are not specific; it may appear as an osteolytic lesion. It can present as a multifocal disease in 40% of cases. No clear correlation with age and sex; however, it is slightly more common in males. Focal neck or back pain is the most common presenting symptom. The natural history of spinal EHE is unpredictable, and currently, there is no standard of care for treatment. Treatment options include preoperative embolization, and surgical resection followed by radiotherapy and/or chemotherapy. A 34-year-old previously healthy male presented with mid-thoracic back pain. Magnetic resonance imaging (MRI) of the spine revealed a decrease in vertebral body height at T5 with an enhancing mass. He underwent T5 balloon kyphoplasty and needle vertebral body biopsy. Results of the biopsy samples were non-diagnostic. Approximately 3 months after surgery, the patient presented with unsteady gait. A subsequent MRI revealed progression of the T5 compression fracture with cord compression. The patient subsequently underwent T4–T6 bilateral posterior decompression for epidural tumor and T3–T7 posterior instrumentation with pedicle screws. Pathology of the lesion revealed EHE. The patient was started on local radiation therapy (RT). On follow-up, 3 months after the second surgery, the thoracic spinal pain had improved dramatically. Our review highlights the diagnosis, clinical presentation, and treatment of spinal EHE. Complete resection is associated with good outcome. Radiotherapy has been used in partially resected lesions. However, the role of radiotherapy as primary treatment is not yet defined. Further studies should develop a treatment algorithm for this rare tumour. PMID:28744509

Capillary hemangiomas are benign tumors found in the skin and soft tissues in younger people. They occur in the central nervous system only rarely, and intradural occurrence is extremely rare. We report here a 60-year-old man presenting with thoracic girdle pain and progressive gait disturbance. Magnetic resonance images of the thoracic spine showed a 12 × 8 × 20 mm, well-defined intradural mass at the T2 level, compressing the spinal cord laterally. Relative to the spinal cord, the mass was hypo- to isointense on T1-weighted images and relatively hyperintense on T2-weighted images, with strong enhancement on contrast-enhanced T1-weighted images. The patient underwent T1-2 hemilaminectomy with resection of the intradural extramedullary tumor, which showed characteristics of a capillary hemangioma on histologic examination. The patient's symptoms improved following the surgery and no clinical or radiological evidence of recurrence was noted at the 2-year follow-up. We present this case with a review of the literature, highlighting features for differential diagnosis. PMID:25045565

The pain associated with vertebral compression fractures can cause significant loss of function and quality of life for older adults. Despite this, there is little consensus on how best to manage this condition. To describe usual care provided by general practitioners (GPs) in Australia for the management of vertebral compression fractures. Data from the Bettering the Evaluation And Care of Health (BEACH) program collected between April 2005 and March 2015 was used for this study. Each year, a random sample of approximately 1,000 GPs each recorded information on 100 consecutive encounters. We selected those encounters at which vertebral compression fracture was managed. Analyses of management options were limited to encounters with patients aged 50 years or over. i) patient demographics; ii) diagnoses/problems managed; iii) the management provided for vertebral compression fracture during the encounter. Robust 95% confidence intervals, adjusted for the cluster survey design, were used to assess significant differences between group means. Vertebral compression fractures were managed in 211 (0.022%; 95% CI: 0.018-0.025) of the 977,300 BEACH encounters recorded April 2005- March 2015. That provides a national annual estimate of 26,000 (95% CI: 22,000-29,000) encounters at which vertebral fractures were managed. At encounters with patients aged 50 years or over (those at higher risk of primary osteoporosis), prescription of analgesics was the most common management action, particularly opioids analgesics (47.1 per 100 vertebral fractures; 95% CI: 38.4-55.7). Prescriptions of paracetamol (8.2; 95% CI: 4-12.4) or non-steroidal anti-inflammatory drugs (4.1; 95% CI: 1.1-7.1) were less frequent. Non-pharmacological treatment was provided at a rate of 22.4 per 100 vertebral fractures (95% CI: 14.6-30.1). At least one referral (to hospital, specialist, allied health care or other) was given for 12.3 per 100 vertebral fractures (95% CI: 7.8-16.8). The prescription of oral opioid analgesics remains the common general practice approach for vertebral compression fractures management, despite the lack of evidence to support this. Clinical trials addressing management of these fractures are urgently needed to improve the quality of care patients receive.

Metastatic disease, myeloma, and lymphoma are the most common malignant spinal tumors. Hemangioma is the most common benign tumor of the spine. Other primary osseous lesions of the spine are more unusual but may exhibit characteristic imaging features that can help the radiologist develop a differential diagnosis. Radiologic evaluation of a patient who presents with osseous vertebral lesions often includes radiography, computed tomography (CT), and magnetic resonance (MR) imaging. Because of the complex anatomy of the vertebrae, CT is more useful than conventional radiography for evaluating lesion location and analyzing bone destruction and condensation. The diagnosis of spinal tumors is based on patient age, topographic features of the tumor, and lesion pattern as seen at CT and MR imaging. A systematic approach is useful for recognizing tumors of the spine with characteristic features such as bone island, osteoid osteoma, osteochondroma, chondrosarcoma, vertebral angioma, and aneurysmal bone cyst. In the remaining cases, the differential diagnosis may include other primary spinal tumors, vertebral metastases and major nontumoral lesions simulating a vertebral tumor, Paget disease, spondylitis, echinococcal infection, and aseptic osteitis. In many cases, vertebral biopsy is warranted to guide treatment.

Abstract Osteoporotic vertebral compression fractures with intraosseous vacuum phenomena could cause persistent back pains in patients, even after receiving conservative treatment. The aim of this study was to evaluate the efficacy of using high-viscosity bone cement via bilateral percutaneous vertebroplasty in treating patients who have osteoporotic vertebral compression fractures with intraosseous vacuum phenomena. Twenty osteoporotic vertebral compression fracture patients with intraosseous vacuum phenomena, who received at least 2 months of conservative treatment, were further treated by injecting high-viscosity bone cement via bilateral percutaneous vertebroplasty due to failure of conservative treatment. Treatment efficacy was evaluated by determining the anterior vertebral compression rates, visual analog scale (VAS) scores, and Oswestry disability index (ODI) scores at 1 day before the operation, on the first day of postoperation, at 1-month postoperation, and at 1-year postoperation. Three of 20 patients had asymptomatic bone cement leakage when treated via percutaneous vertebroplasty; however, no serious complications related to these treatments were observed during the 1-year follow-up period. A statistically significant improvement on the anterior vertebral compression rates, VAS scores, and ODI scores were achieved after percutaneous vertebroplasty. However, differences in the anterior vertebral compression rate, VAS score, and ODI score in the different time points during the 1-year follow-up period was not statistically significant (P > 0.05). Within the limitations of this study, the injection of high-viscosity bone cement via bilateral percutaneous vertebroplasty for patients who have osteoporotic vertebral compression fractures with intraosseous vacuum phenomena significantly relieved their back pains and improved their daily life activities shortly after the operation, thereby improving their life quality. In this study, the use of high-viscosity bone cement reduced the leakage rate and contributed to their successful treatment, as observed in patients during the 1-year follow-up period. PMID:28383423

The stress/strain distribution in the human vertebrae has seldom been measured, and only for a limited number of loading scenarios, at few locations on the bone surface. This in vitro study aimed at measuring how strain varies on the surface of the lumbar vertebral body and how such strain pattern depends on the loading conditions. Eight cadaveric specimens were instrumented with eight triaxial strain gauges each to measure the magnitude and direction of principal strains in the vertebral body. Each vertebra was tested in a three adjacent vertebrae segment fashion. The loading configurations included a compressive force aligned with the vertebral body but also tilted (15°) in each direction in the frontal and sagittal planes, a traction force, and torsion (both directions). Each loading configuration was tested six times on each specimen. The strain magnitude varied significantly between strain measurement locations. The strain distribution varied significantly when different loading conditions were applied (compression vs. torsion vs. traction). The strain distribution when the compressive force was tilted by 15° was also significantly different from the axial compression. Strains were minimal when the compressive force was applied coaxial with the vertebral body, compared with all other loading configurations. Also, strain was significantly more uniform for the axial compression, compared with all other loading configurations. Principal strains were aligned within 19° to the axis of the vertebral body for axial-compression and axial-traction. Conversely, when the applied force was tilted by 15°, the direction of principal strain varied by a much larger angle (15° to 28°). This is the first time, to our knowledge, that the strain distribution in the vertebral body is measured for such a variety of loading configurations and a large number of strain sensors. The present findings suggest that the structure of the vertebral body is optimized to sustain compressive forces, whereas even a small tilt angle makes the vertebral structure work under suboptimal conditions.

We report a 58-year-old man showing spastic paraparesis due to medulla oblongata compression by tortuous vertebral arteries. He noticed weakness of both legs and gait disturbance at the age of 58 years and his symptoms progressively worsened during the following several months. General physical findings were normal. Blood pressure was normal and there were no signs of arteriosclerosis. Neurological examination on admission revealed lower-limb-dominant spasticity in all four extremities, lower-limb weakness, hyperreflexia in all extremities with positive Wartenberg's, Babinski's and Chaddock's signs, mild hypesthesia and hypopallesthesia in both lower limbs, and spastic gait. Cranial nerves were all normal. Serum was negative for antibodies against human T-cell lymphotropic virus-1 antibody. Nerve conduction and needle electromyographic studies of all four limbs revealed normal findings. Cervical, thoracic and lumbo-sacral magnetic resonance imaging (MRI) findings were all normal. Brain MRI and magnetic resonance angiography demonstrated bilateral tortuous vertebral arteries compressing the medulla oblongata. Neurovascular decompression of the right vertebral artery was performed because compression of the right side was more severe than that of the left side. Post-operative MRI revealed outward translocation of the right vertebral artery and relieved compression of the medulla oblongata on the right side. The patient's symptoms and neurological findings improved gradually after the operation. Bilateral pyramidal tract signs without cranial nerve dysfunction due to compression of the medulla oblongata by tortuous vertebral arteries are extremely rare and clinically indistinguishable from hereditary spastic paraplegia (HSP). Although we did not perform a genetic test for HSP, we consider that the spastic paraparesis and mild lower-limb hypesthesia were caused by compression of the medulla oblongata by bilateral tortuous vertebral arteries based on the post-operative improvement in symptoms. Given the favorable effects of surgery, tortuous vertebral arteries should be considered in the differential diagnosis of patients presenting with progressive spastic paraparesis.

To test the nickel-titanium (Ni-Ti) shape memory alloys of vertebral body reduction fixator with assisted distraction bar for the treatment of traumatic and osteoporotic vertebral body fracture. A Ni-Ti shape memory alloys of vertebral body reduction fixator with assisted distraction bar was implanted into the compressed fracture specimens through vertebral pedicle with the radiographic monitoring to reduce the collapsed endplate as well as distract the compressed vertebral fracture. Radiographic film and computed tomographic reconstruction technique were employed to evaluate the effects of reduction and distraction. A biomechanic test machine was used to measure the fatigue and the stability of deformation of fixation segments. Relying on the effect of temperature shape memory, such an assembly could basically reduce the collapsed endplate as well as distract the compressed vertebral fracture. And when unsatisfied results of reduction and distraction occurred, its super flexibility could provide additional distraction strength. A Ni-Ti shape memory alloys of vertebral body reduction fixator with assisted distraction bar may provide effective endplate reduction, restore the vertebral height and the immediate biomechanic spinal stability. So the above assembly is indicated for the treatment of traumatic and osteoporotic vertebral body fracture.

Recent findings suggest that vertebral osteophytes increase the resistance of the spine to compression. However, the role of vertebral osteophytes on the biomechanical response of the spine under fast dynamic compression, up to failure, is unclear. Seventeen human spine specimens composed of three vertebrae (from T5-T7 to T11-L1) and their surrounding soft tissues were harvested from nine cadavers, aged 77 to 92 years. Specimens were imaged using quantitative computer tomography (QCT) for medical observation, classification of the intervertebral disc degeneration (Thomson grade) and measurement of the vertebral trabecular density (VTD), height and cross-sectional area. Specimens were divided into two groups (with (n = 9) or without (n = 8) substantial vertebral body osteophytes) and compressed axially at a dynamic displacement rate of 1 m/s, up to failure. Normalized force-displacement curves, videos and QCT images allowed characterizing failure parameters (force, displacement and energy at failure) and fracture patterns. Results were analyzed using chi-squared tests for sampling distributions and linear regression for correlations between VTD and failure parameters. Specimens with substantial vertebral body osteophytes present higher stiffness (2.7 times on average) and force at failure (1.8 times on average) than other segments. The presence of osteophytes significantly influences the location, pattern and type of fracture. VTD was a good predictor of the dynamic force and energy at failure for specimens without substantial osteophytes. This study also showed that vertebral body osteophytes provide a protective mechanism to the underlying vertebra against severe compression fractures. PMID:29065144

The presence of a vertebral compression fracture is highly indicative of osteoporosis and represents the single most robust predictor for development of a second osteoporotic fracture in the spine or elsewhere. Less than one third of vertebral compression fractures are diagnosed clinically. We present an automated method for detecting spine compression fractures in Computed Tomography (CT) scans. The algorithm is composed of three processes. First, the spinal column is segmented and sagittal patches are extracted. The patches are then binary classified using a Convolutional Neural Network (CNN). Finally a Recurrent Neural Network (RNN) is utilized to predict whether a vertebral fracture is present in the series of patches.

Multiple cutaneous infantile hemangiomas have been associated with hepatic hemangiomas. Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. The aim of this study was to determine the frequency with which hepatic hemangiomas occur in infants with five or more cutaneous infantile hemangiomas compared to those with one to four cutaneous infantile hemangiomas and to characterize the clinical features of these hepatic hemangiomas. A multicenter prospective study of children with cutaneous infantile hemangiomas was conducted at pediatric dermatology clinics at Hemangioma Investigator Groups sites in the United States, Canada, and Spain between October 2005 and December 2008. Data were collected, and abdominal ultrasonography was performed on infants younger than 6 months old with five or more cutaneous infantile hemangiomas and those with one to four cutaneous infantile hemangiomas. Twenty-four (16%) of the 151 infants with five or more cutaneous infantile hemangiomas had hepatic hemangiomas identified on abdominal ultrasound, versus none of the infants with fewer than five (p = 0.003). Two of the 24 infants with hepatic hemangiomas received treatment specifically for their hepatic hemangiomas. Infants with five or more cutaneous infantile hemangiomas have a statistically significantly greater frequency of hepatic hemangiomas than those with fewer than 5. These findings support the recommendation of five or more cutaneous infantile hemangiomas as a threshold for screening infants younger than 6 months old for hepatic hemangiomas but also demonstrate that the large majority of these infants with hepatic hemangiomas do not require treatment. © 2011 Wiley Periodicals, Inc.

To investigate the risk factors of cement leakage in percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (OVCF). Between March 2011 and March 2012, 98 patients with single level OVCF were treated by PVP, and the clinical data were analyzed retrospectively. There were 13 males and 85 females, with a mean age of 77.2 years (range, 54-95 years). The mean disease duration was 43 days (range, 15-120 days), and the mean T score of bone mineral density (BMD) was -3.8 (range, -6.7- -2.5). Bilateral transpedicular approach was used in all the patients. The patients were divided into cement leakage group and no cement leakage group by occurrence of cement leakage based on postoperative CT. Single factor analysis was used to analyze the difference between 2 groups in T score of BMD, operative level, preoperative anterior compression degree of operative vertebrae, preoperative middle compression degree of operative vertebrae, preoperative sagittal Cobb angle of operative vertebrae, preoperative vertebral body wall incompetence, cement volume, and volume ratio of intravertebral bone cement to vertebral body. All relevant factors were introduced to logistic regression analysis to analyze the risk factors of cement leakage. All procedures were performed successfully. The mean operation time was 40 minutes (range, 30-50 minutes), and the mean volume ratio of intravertebral bone cement to vertebral body was 24.88% (range, 7.84%-38.99%). Back pain was alleviated significantly in all the patients postoperatively. All patients were followed up with a mean time of 8 months (range, 6-12 months). Cement leakage occurred in 49 patients. Single factor analysis showed that there were significant differences in the volume ratio of intravertebral bone cement to vertebral body and preoperative vertebral body wall incompetence between 2 groups (P < 0.05), while no significant difference in T score of BMD, operative level, preoperative anterior compression degree of operative vertebrae, preoperative middle compression degree of operative vertebrae, preoperative sagittal Cobb angle of operative vertebrae, and cement volume (P > 0.05). The logistic regression analysis showed that the volume ratio of intravertebral bone cement to vertebral body (P < 0.05) and vertebral body wall incompetence (P < 0.05) were the risk factors for occurrence of cement leakage. The volume ratio of intravertebral bone cement to vertebral body and vertebral body wall incompetence are risk factors of cement leakage in PVP for OVCF. Cement leakage is easy to occur in operative level with vertebral body wall incompetence and high volume ratio of intravertebral bone cement to vertebral body.

Untreated vertebral compression fractures can have serious clinical consequences and impose a considerable impact on patients' quality of life and on caregivers. Since non-surgical management of these fractures has limited effectiveness, vertebral augmentation procedures are gaining acceptance in clinical practice for pain control and fracture stabilization. The objective of this analysis was to determine the cost-effectiveness and budgetary impact of kyphoplasty or vertebroplasty compared with non-surgical management for the treatment of vertebral compression fractures in patients with cancer. We performed a systematic review of health economic studies to identify relevant studies that compare the cost-effectiveness of kyphoplasty or vertebroplasty with non-surgical management for the treatment of vertebral compression fractures in adults with cancer. We also performed a primary cost-effectiveness analysis to assess the clinical benefits and costs of kyphoplasty or vertebroplasty compared with non-surgical management in the same population. We developed a Markov model to forecast benefits and harms of treatments, and corresponding quality-adjusted life years and costs. Clinical data and utility data were derived from published sources, while costing data were derived using Ontario administrative sources. We performed sensitivity analyses to examine the robustness of the results. In addition, a 1-year budget impact analysis was performed using data from Ontario administrative sources. Two scenarios were explored: (a) an increase in the total number of vertebral augmentation procedures performed among patients with cancer in Ontario, maintaining the current proportion of kyphoplasty versus vertebroplasty; and (b) no increase in the total number of vertebral augmentation procedures performed among patients with cancer in Ontario but an increase in the proportion of kyphoplasties versus vertebroplasties. The base case considered each of kyphoplasty and vertebroplasty versus non-surgical management. Kyphoplasty and vertebroplasty were associated with an incremental cost-effectiveness ratio of $33,471 and $17,870, respectively, per quality-adjusted life-year gained. The budgetary impact of funding vertebral augmentation procedures for the treatment of vertebral compression fractures in adults with cancer in Ontario was estimated at about $2.5 million in fiscal year 2014/15. More widespread use of vertebral augmentation procedures raised total expenditures under a number of scenarios, with costs increasing by $67,302 to $913,386. Our findings suggest that the use of kyphoplasty or vertebroplasty in the management of vertebral compression fractures in patients with cancer may be a cost-effective strategy at commonly accepted willingness-to-pay thresholds. Nonetheless, more widespread use of kyphoplasty (and vertebroplasty to a lesser extent) would likely be associated with net increases in health care costs.

Infantile hemangiomas of the lip are potentially problematic because of high visibility and risk of disfigurement and ulceration. This study examined sizes, patterns, and locations of lip hemangiomas, their prognostic value, and their implications in hemangioma pathogenesis. Records of 106 patients seen for lip hemangiomas from 2006 to 2013 at Nationwide Children's Hospital were reviewed. Localized hemangiomas were mapped to a location on the lip based on their focus. Size, location, and morphology were assessed with regard to outcome. Poor outcomes were considered to be marked anatomic deformity, scarring, functional complications, and ulceration. Of 72 untreated hemangiomas with discernible outcomes, 92% of segmental lip hemangiomas were associated with poor outcomes, as opposed to 32% of localized hemangiomas (p < 0.001). Localized lip hemangiomas originated from six distinct locations. Localized untreated hemangiomas with poor outcomes were, on average, approximately 2.36 cm(2) larger (95% confidence interval 1.47, 3.25) than those that resolved favorably (p < 0.001); 52% of upper lip untreated hemangiomas and 6% of lower lip hemangiomas had poor outcomes (p = 0.001), and 61% of untreated localized hemangiomas involving the vermilion border and 25% of those that did not had poor outcomes (p = 0.01). Hemangiomas that received early medical or surgical intervention were less likely to have poor outcomes than untreated hemangiomas (p = 0.03). Localized lip hemangiomas occur in distinct locations on the lip that are not random and appear to reflect known models of facial development. Segmental morphology is associated with poor outcomes. In localized hemangiomas, the upper lip is associated with more problematic outcomes than the lower lip. Large size and involvement of the vermilion border are also valuable prognostic indicators associated with poor outcomes. Early intervention in lip hemangiomas is associated with better outcomes. © 2016 Wiley Periodicals, Inc.

Fat embolism after long bone and pelvic fractures as well as orthopedic interventions is a well-documented phenomenon, but it is highly unusual after isolated vertebral fractures. We report a case of fatal fat embolism in a 78-year-old man after an isolated vertebral compression fracture with no related orthopedic intervention. A high index of suspicion is necessary for early diagnosis and successfully treating this unusual complication. PMID:20229119

Vertebral haemangiomas are recognized to be one of the commonest benign tumours of the vertebral column, occurring mostly in the thoracic spine. The vast majority of these are asymptomatic. Infrequently, these can turn symptomatic and cause neurological deficit (cord compression) through any of four reported mechanisms: (1) epidural extension; (2) expansion of the involved vertebra(e) causing spinal canal stenosis; (3) spontaneous epidural haemorrhage; (4) pathological burst fracture. Thoracic haemangiomas have been reported to be more likely to produce cord compression than lumbar haemangiomas. A forty-nine year old male with acute onset spinal cord compression from a pathological fracture in a first lumbar vertebral haemangioma. An MRI delineated the haemangioma and extent of bleeding that caused the cord compression. These were confirmed during surgery and the haematoma was evacuated. The spine was instrumented from T12 to L2, and a cement vertebroplasty was performed intra-operatively. Written consent for publication was obtained from the patient. The junctional location of the first lumbar vertebra, and the structural weakness from normal bone being replaced by the haemangioma, probably caused it to fracture under axial loading. This pathological fracture caused bleeding from the vascularized bone, resulting in cord compression.

Background Untreated vertebral compression fractures can have serious clinical consequences and impose a considerable impact on patients' quality of life and on caregivers. Since non-surgical management of these fractures has limited effectiveness, vertebral augmentation procedures are gaining acceptance in clinical practice for pain control and fracture stabilization. The objective of this analysis was to determine the cost-effectiveness and budgetary impact of kyphoplasty or vertebroplasty compared with non-surgical management for the treatment of vertebral compression fractures in patients with cancer. Methods We performed a systematic review of health economic studies to identify relevant studies that compare the cost-effectiveness of kyphoplasty or vertebroplasty with non-surgical management for the treatment of vertebral compression fractures in adults with cancer. We also performed a primary cost-effectiveness analysis to assess the clinical benefits and costs of kyphoplasty or vertebroplasty compared with non-surgical management in the same population. We developed a Markov model to forecast benefits and harms of treatments, and corresponding quality-adjusted life years and costs. Clinical data and utility data were derived from published sources, while costing data were derived using Ontario administrative sources. We performed sensitivity analyses to examine the robustness of the results. In addition, a 1-year budget impact analysis was performed using data from Ontario administrative sources. Two scenarios were explored: (a) an increase in the total number of vertebral augmentation procedures performed among patients with cancer in Ontario, maintaining the current proportion of kyphoplasty versus vertebroplasty; and (b) no increase in the total number of vertebral augmentation procedures performed among patients with cancer in Ontario but an increase in the proportion of kyphoplasties versus vertebroplasties. Results The base case considered each of kyphoplasty and vertebroplasty versus non-surgical management. Kyphoplasty and vertebroplasty were associated with an incremental cost-effectiveness ratio of $33,471 and $17,870, respectively, per quality-adjusted life-year gained.

Vertebral compression fractures caused by osteoporosis are among the most common fractures in the elderly. The treatment focuses on pain control, maintenance of independence, and management of the osteoporosis. Elderly patients often encounter adverse effects to pain medications, do not tolerate bed rest, and are not ideal candidates for invasive spinal reconstructive surgery. Percutaneous vertebral augmentation (vertebroplasty or kyphoplasty) has become popular as a less-invasive alternative. However, studies have questioned the effectiveness of these procedures. The authors conducted a MEDLINE search using relevant search terms including osteoporosis, osteoporotic vertebral compression fracture, elderly, kyphoplasty and vertebroplasty. Two elderly patients presented with a fracture of their third and first lumbar vertebral body, respectively. One patient progressed well with conservative treatment, whereas the other patient was hospitalized secondary to pain after conservative measures failed to offer improvement. The hospitalized patient subsequently opted for a kyphoplasty and was able to resume his normal daily activities after the procedure. Selecting patients on an individual case-by-case basis can optimize the effectiveness and outcomes of a vertebral augmentation. This process includes the documentation of an osteoporotic vertebral compression fracture with the aide of imaging studies, including the acuity of the fracture as well as the correlation with the physical examination findings. Patients who are functional and improving under a conservative regimen are not candidates for kyphoplasty. However, if the conservative management is not successful after 4 to 6 weeks and the patient is at risk to become bedridden, an augmentation should be considered. A kyphoplasty procedure may be preferred over vertebroplasty, given the lower risk profile and better outcomes regarding spinal alignment. Published by Elsevier HS Journals, Inc.
The establishment of the hemangioma model in nude mouse.

Hemangioma is one of the most common benign tumors in children. Most of them could regress spontaneously; however, the pathogenesis and triggering of regression are still unknown. Here, we introduce a new means in which the specimen of human hemangioma was transplanted into nude mice subcutaneously. At the same time, high dose of estradiol was administered to the experimental nude mice intramuscularly to promote implantation and proliferation of hemangioma endothelial cells. By this means, a credible animal model of human hemangioma was established. Further studies on pathogenesis and medical intervention of hemangioma could be carried on with this model. The specimen of grafted hemangioma was taken from a 6-month-old girl, in whom the hemangioma grew rapidly, by surgery. The fresh estrogen receptor-positive strawberry hemangioma specimens were sliced and inoculated subcutaneously into 16 nude mice that were divided randomly into 2 groups, namely, group 1 (n = 8) with normal diet and group 2 (n = 8) with normal diet and 10(-7) mg estradiol administered intramuscularly every week additionally. The size of grafts was measured weekly. All of the experimental mice were killed at 90 days after graft. Hemangioma tissues were harvested and sliced into 4 to 5 microm sections. Living grafts were subjected to histopathologic examination and immunohistochemistry for CD34 and Ki-67. All of the sizes of hemangioma tissues in group 1 were diminished distinctly in 30 days. Thirteen samples of hemangioma were almost absorbed and disappeared completely in 90 days. The sizes of hemangioma in group 2 were larger than primary specimens. It was observed from the section of hemangioma that endothelial cells proliferate vividly and fresh capillary blood vessels grew up into the body of hemangioma. The mean positive cell rate of CD34 in group 2 was 48.49 +/- 3.90 and the Ki-67 was 15.04 +/- 2.44. The transplanted tumor cell retained the histologic characters of original tumor. The capillary hemangioma model established in nude mice retains almost all the biologic character of original human hemangioma and could be widely used in further study on hemangioma.

To report on a series of vascular tumors of the iris. Noncomparative case series. A retrospective medical record review of all patients with an iris vascular tumor was performed to identify the clinical features and develop a simple classification of these lesions. Included were demographics, clinical features, systemic associations, complications, management, and histopathology. There were 54 eyes in 45 patients with an iris vascular tumor. These were categorized as racemose hemangioma (41 eyes: 29 simple and 12 complex), cavernous hemangioma (3 eyes: 2 localized and 1 systemic), capillary hemangioma (1 eye, localized), varix (3 eyes, localized), and microhemangiomatosis (6 eyes, localized). The hemangiomas occurred in adults at a median age of 55 years, whereas capillary hemangioma occurred in infancy and cavernous hemangioma with systemic involvement occurred in a child. Of the 41 eyes with iris racemose hemangioma, none showed systemic involvement. Of all 54 eyes, transient hyphema was the main complication, found at some point in 30% or more of each affected eye except for iris capillary and racemose hemangioma. Surgical resection was necessary in 1 cavernous hemangioma and 1 varix. The remainder were managed with observation. There are now well-documented examples of iris racemose hemangioma, cavernous hemangioma, capillary hemangioma, varix, and microhemangiomatosis. Transient hyphema is the main complication. Observation is usually advised. Most are solitary lesions confined to the iris and some (cavernous hemangioma and microhemangiomatosis) can have important systemic associations.

Hemangiomas are the most common benign tumor of infancy. Most hemangiomas remain asymptomatic and can be managed by close observation; however, immediate treatment is indicated for hemangiomas that may cause significant complications. Periocular hemangiomas warrant close evaluation and early, active treatment of those with the potential to threaten or permanently compromise vision. Herein we review the clinical features of periocular hemangiomas, differential diagnosis, possible ophthalmologic complications and sequelae, and therapeutic modalities.

Previous studies in humans have reported that the dimensions of the intervertebral foramina change significantly with movement of the spine. Cervical spondylomyelopathy (CSM) in dogs is characterized by dynamic and static compressions of the neural components, leading to variable degrees of neurologic deficits and neck pain. Studies suggest that intervertebral foraminal stenosis has implications in the pathogenesis of CSM. The dimensions of the cervical intervertebral foramina may significantly change during neck movements. This could have implication in the pathogenesis of CSM and other diseases associated with radiculopathy such as intervertebral disc disease. The purpose of this study was to quantify the morphological changes in the intervertebral foramina of dogs during flexion, extension, traction, and compression of the canine cervical vertebral column. All vertebral columns were examined with magnetic resonance imaging prior to biomechanic testing. Eight normal vertebral columns were placed in Group 1 and eight vertebral columns with intervertebral disc degeneration or/and protrusion were assigned to Group 2. Molds of the left and right intervertebral foramina from C4-5, C5-6 and C6-7 were taken during all positions and loading modes. Molds were frozen and vertical (height) and horizontal (width) dimensions of the foramina were measured. Comparisons were made between neutral to flexion and extension, flexion to extension, and traction to compression in neutral position. Extension decreased all the foraminal dimensions significantly, whereas flexion increased all the foraminal dimensions significantly. Compression decreased all the foraminal dimensions significantly, and traction increased the foraminal height, but did not significantly change the foraminal width. No differences in measurements were seen between groups. Our results show movement-related changes in the dimensions of the intervertebral foramina, with significant foraminal narrowing in extension and compression.

Cavernous hemangioma is also called as 'ANGIOMA CAVERNOSUM' or 'CAVERNOMA' as benign lesion of blood vessels. They are similar to strawberry hemangioma but deeply situated. Although most often associated with skin it is also sometimes found in mucous membrane, brain and the viscera. The diagnosis of hemangiomas is mainly based on clinical evaluation . Isolated hemangiomas in the tonsillar tissue is a rare occurance. In this we report had a case of adult tonsillar hemangioma of left side associated with recurrent tonsillitis . He was effectively managed surgically without any complications.
Rapid onset aggressive vertebral haemangioma.

Vertebral haemangiomas are generally benign asymptomatic vascular tumours seen commonly in the adult population. Presentations in paediatric populations are extremely rare, which can result in rapid onset of neurological symptoms. We present a highly unusual case of an aggressive paediatric vertebral haemangioma causing significant cord compression. A 13-year-old boy presented with only 2 weeks duration of progressive gait disturbance, truncal ataxia and loss of bladder control. Magnetic resonance imaging (MRI) of the spine revealed a large vascular epidural mass extending between T6 and T8 vertebral bodies. Associated displacement and compression of the spinal cord was present. A highly vascular bony lesion was found during surgery. Histopathology identified this tumour to be a vertebral haemangioma. We present an extremely unusual acute presentation of a paediatric vertebral haemangioma. This study highlights the need for early diagnosis, MRI for investigation and urgent surgical management. © Springer-Verlag 2011

To evaluate fresh blood imaging (FBI), a magnetic resonance imaging technique that does not use contrast, for identifying hemangiomas and feeding arteries in the oral and maxillofacial regions. For 16 patients with hemangiomas, FBI visualizations of hemangiomas and feeding arteries in the oral and maxillofacial regions were compared with those from 3-dimensional (3D) phase-contrast magnetic resonance angiography (PC-MRA). Comparisons were based on the conspicuities of blood vessels and the 3D relationships of hemangiomas with the surrounding blood vessels. The conspicuity of hemangiomas, feeding arteries, and blood vessels were significantly better with FBI than with PC-MRA. After differentiating arteries from veins, 3D visualizations of hemangiomas and arteries or veins could be performed with FBI. FBI is a useful method in oral and maxillofacial regions for identifying the relationships between hemangiomas and the surrounding arteries or veins. Crown Copyright © 2012. Published by Mosby, Inc.

The risk factors for cement leakage were retrospectively reviewed in 192 patients who underwent percutaneous vertebral augmentation (PVA). To discuss the factors related to the cement leakage in PVA procedure for the treatment of osteoporotic vertebral compression fractures. PVA is widely applied for the treatment of osteoporotic vertebral fractures. Cement leakage is a major complication of this procedure. The risk factors for cement leakage were controversial. A retrospective review of 192 patients who underwent PVA was conducted. The following data were recorded: age, sex, bone density, number of fractured vertebrae before surgery, number of treated vertebrae, severity of the treated vertebrae, operative approach, volume of injected bone cement, preoperative vertebral compression ratio, preoperative local kyphosis angle, intraosseous clefts, preoperative vertebral cortical bone defect, and ratio and type of cement leakage. To study the correlation between each factor and cement leakage ratio, bivariate regression analysis was employed to perform univariate analysis, whereas multivariate linear regression analysis was employed to perform multivariate analysis. The study included 192 patients (282 treated vertebrae), and cement leakage occurred in 100 vertebrae (35.46%). The vertebrae with preoperative cortical bone defects generally exhibited higher cement leakage ratio, and the leakage is typically type C. Vertebrae with intact cortical bones before the procedure tend to experience type S leakage. Univariate analysis showed that patient age, bone density, number of fractured vertebrae before surgery, and vertebral cortical bone were associated with cement leakage ratio (P<0.05). Multivariate analysis showed that the main factors influencing bone cement leakage are bone density and vertebral cortical bone defect, with standardized partial regression coefficients of -0.085 and 0.144, respectively. High bone density and vertebral cortical bone defect are independent risk factors associated with bone cement leakage.

Osteoporotic vertebral compression fracture, always accompanied with pain and height loss of vertebral body, has a significant negative impact on life quality of patients. Vertebroplasty or kyphoplasty is minimal invasive techniques to reconstruct the vertebral height and prevent further collapse of the fractured vertebrae by injecting polymethylmethacrylate into vertebral body. However, recompression of polymethylmethacrylate augmented vertebrae with significant vertebral height loss and aggressive local kyphotic was observed frequently after VP or KP. The purpose of this study was to investigate the effect of polymethylmethacrylate distribution on recompression of the vertebral body after vertebroplasty or kyphoplasty surgery for osteoporotic vertebral compression fracture. A total of 281 patients who were diagnosed with vertebral compression fracture (T5-L5) from June 2014 to June 2016 and underwent vertebroplasty or kyphoplasty by polymethylmethacrylate were retrospectively analyzed. The X-ray films at 1 day and 12 months after surgery were compared to evaluate the recompression of operated vertebral body. Patients were divided into those without recompression (non-recompression group) and those with recompression (recompression group). Polymethylmethacrylate distribution pattern, including location and relationship to endplates, was compared between the two groups by lateral X-ray film. Multivariate logistic regression analysis was performed to assess the potential risk factors associated with polymethylmethacrylate distribution for recompression. One hundred and six (37.7%) patients experienced recompression after surgery during the follow-up period. The polymethylmethacrylate distributed in the middle of vertebral body showed significant differences between two groups. In non-recompression group, the polymethylmethacrylate in the middle portion of vertebral body were closer to endplates than that in the recompression group (upper: t = 31.41, p<0.001; lower: t = 12.19, p<0.001). The higher percentage of the height of polymethylmethacrylate in the middle portion of vertebral body indicates the lower risk of recompression (odds ratio [OR]<0.01, p<0.001). The recompression group and non-recompression group showed significant difference in "contacted" polymethylmethacrylate distribution pattern (polymethylmethacrylate contacted to the both upper/lower endplates) (χ2 = 66.23, p<0.001). The vertebra with a "contacted" polymethylmethacrylate distribution pattern has lower risk of recompression (OR = 0.09, p<0.001). Either more polymethylmethacrylate in the middle portion of vertebral body or "contacted" polymethylmethacrylate distribution pattern had a significantly less incidence of recompression. The findings indicated that the control of polymethylmethacrylate distribution during surgery may reduce the risks of recompression after vertebroplasty or kyphoplasty.

There are few reports on hemiparesis caused by vascular medullary compression, which can occur because of dolichoectasia of the vertebrobasilar arterial system. In this article, we report a case of vertebral artery compression of the medulla oblongata in a 67-year-old woman. The patient was hypertensive, and she developed hemiparesis and intermittent spasms over 5 years. These spasms had worsened during the last year. Cranial nerve magnetic resonance imaging showed compression of the medulla oblongata by the left vertebral artery. A motor evoked potential (MEP) examination showed abnormal conduction of MEPs of bilateral toe abductors. The patient underwent microvascular decompression surgery under general anesthesia through a retrosigmoid keyhole approach. This operation led to relief of vascular compression and symptomatic improvement. Our case suggests that detailed history, imaging studies, and electrophysiologic studies help lead to a correct and early diagnosis of hemiparesis caused by vascular compression of the rostral ventrolateral medulla. Microvascular decompression surgery improves patient symptoms, and intraoperative electrophysiologic monitoring helps to avoid injury to important adjacent nerves. Copyright © 2017 Elsevier Inc.

Quiescent Volcano-Chest Wall Hemangioma.
Saldanha, Elroy; Martis, John J S; Kumar, B Vinod; D'Cunha, Rithesh J; Vijin, V
2017-08-01
Chest wall hemangiomas are rare tumors that may originate within the soft tissue or from the ribs. Intramuscular hemangioma is infrequent, representing less than 1 % of all hemangiomas, and the localization in the chest wall is even less frequent. They are typically cutaneous in location, large, and poorly circumscribed and can be locally destructive. We present a case of a 34-year-old lady presented with firm lump 3 × 3 cm in left upper and inner quadrant of left breast well defined borders, non-pulsatile and restricted mobility. Sono-mammogram was suggestive of ill-defined lesion at 10 o'clock position. CT chest was conclusive of chest wall hemangioma. The patient underwent excision of the lump. HPE was suggestive of cavernous hemangioma. Cavernous hemangioma typically manifest at birth or before the age of 30 years. CT is more sensitive than plain radiography in detecting phleboliths, which are present in approximately 30 % of cavernous hemangiomas. Surgical excision would be treatment of choice. In this case, the site of the lesion was in the breast clinically mimicking that of a fibroadenoma which warrants hemangioma as a differential diagnosis.

To describe diagnostic findings, surgical technique, and outcome in dogs with thoracic spinal canal stenosis and vertebral instability secondary to congenital vertebral anomalies. Retrospective clinical study. Dogs (n=9) with thoracic spinal canal stenosis. Medical records (1995-1996; 2000-2006) of 9 dogs with a myelographic diagnosis of spinal canal stenosis and/or vertebral instability secondary to congenital vertebral anomaly that were surgically managed by vertebral stabilization with or without laminectomy were reviewed. Data on pre- and postoperative neurologic status, diagnostic findings, surgical techniques, and outcomes were retrieved. Follow-up evaluations were performed at 1, 2, and 6 months. Long-term outcome was assessed by means of clinical examination or owner telephone interviews. Spinal cord compression was confirmed by myelography, and in 2 dogs, dynamic compression by stress myelography. Eight dogs regained the ability to ambulate postoperatively. One dog with a partial recovery regained voluntary movement but did not become ambulatory. Spinal cord injury secondary to congenital vertebral anomaly may have a good outcome when treated by vertebral stabilization with or without laminectomy. Adequate stabilization of the vertebrae and improved neurologic outcome were achieved in most dogs. Vertebral stabilization using positively threaded profile pins and polymethylmethacrylate with or without laminectomy is an effective treatment for spinal canal stenosis and vertebral instability secondary to congenital thoracic vertebral anomalies.

Percutaneous vertebroplasty has been widely applied in the treatment of osteoporotic vertebral compression fractures over the past two decades. However as one of the major complications, the rate of cement leakage seems not to be decreased significantly. In this study, the rate of cement leakage was compared between two groups using two different cement injection cannulas. The purpose was to determine the efficacy of side-opening cannula on preventing cement leakage in vertebroplasty for the treatment of osteoporotic vertebral compression fractures. A retrospective study was conducted from January 2013 to December 2015. Totally 225 patients who received bilateral vertebroplasty due to osteoporotic vertebral compression fractures were included in the study. The patients were divided into test group who received vertebroplasty with side-opening cannulas and control group who received vertebroplasty with front-opening cannulas. The patients' medical records were reviewed to determine the bone marrow density, preoperative vertebral compression ratio, preoperative and postoperative VAS, operation time, volume of injected bone cement, rate of cement leakage. Post-operative X-rays and CT scans were utilized to assess the degree of Cement leakage. Comparisons between groups and clinical results on VAS in each group were analyzed with appropriate test. All the patients were performed successfully without symptomatic complications. The back pain was significantly relieved after operation in both groups (P < 0.05). At 6 days and 6 months follow-up, there was no significant difference in the mean VAS score between the two groups (P > 0.05). The rate of cement leakage in the test group was significantly lower than that in the control group (P < 0.05). Percutaneous vertebroplasty with side-opening cannula is a safe and effective minimally invasive method in the treatment of osteoporotic vertebral compression fractures, the rate of cement leakage can be significantly reduced by redirecting the cement flow.

Hemangioma of the rib is a rare benign tumor that is often difficult to distinguish from malignant bone tumors. Rib hemangioma often shows bony disruption with a slight cortical disruption, extraosseous lesion, and expanded bone on computed tomography (CT). We report the case of a 68-year-old man with atypical rib hemangioma with a slight cortical disruption and no expanded bone. The tumor showed relatively high 18FDG-uptake on positron emission tomography (PET)/CT. Rib hemangioma often shows higher 18FDG-uptake. PET/CT may not provide useful information for distinguishing rib hemangioma from a malignant tumor. Close observation without surgical resection may be feasible if the tumor is diagnosed as a rib hemangioma by biopsy. PMID:28959457

Our study aim was to clarify the characteristics of hemangiomas with pseudo washout sign (PWS) by comparing their features with those of hemangiomas without PWS on gadolinium-ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance (MR) imaging. We evaluated the features of hemangiomas on Gd-EOB-DTPA-enhanced MR imaging of 70 hepatic hemangiomas in 31 patients, investigating the presence of peripheral or central nodular enhancement, diffuse enhancement, and arterioportal shunt during the arterial phase, fill-in enhancement during the portal venous phase, and PWS, which is low signal intensity during the late phase. We visually assessed the intensity of contrast enhancement of the lesion during the arterial, portal venous, late, and hepatobiliary phases using a 4-grade scale and used the Fisher exact and Mann-Whitney U tests to compare hemangiomas with and without PWS. We observed PWS in 33 (47%) of 70 hemangiomas, which were significantly smaller than the hemangiomas without PWS (17.4 mm ± 20.3 versus 30.1 mm ± 28.5; P = 0.005); more frequent diffuse enhancement in hemangiomas with PWS than those without (21.2% versus 2.7%; P = 0.026); and no significant differences in nodular enhancement (P = 0.231), arterioportal shunt (P = 0.403), or fill-in enhancement (P = 0.357) between hemangiomas with and without PWS. Visually determined grades of tumor contrast enhancement were significantly lower in hemangiomas with PWS during the portal venous (P = 0.007) and late (P < 0.001) phases. Small hemangiomas tend to decrease in signal intensity during the portal venous phase and show PWS during the late phase.

Purpose Postvertebral augmentation vertebral compression fractures are common; repeated vertebral augmentation is usually performed for prompt pain relief. This study aimed to evaluate the incidence and risk factors of repeat vertebral augmentation. Methods We performed a retrospective, nationwide, population-based longitudinal observation study, using the National Health Insurance Research Database (NHIRD) of Taiwan. All patients who received vertebral augmentation for vertebral compression fractures were evaluated. The collected data included patient characteristics (demographics, comorbidities, and medication exposure) and repeat vertebral augmentation. Kaplan–Meier and stratified Cox proportional hazard regressions were performed for analyses. Results The overall incidence of repeat vertebral augmentation was 11.3% during the follow-up until 2010. Patients with the following characteristics were at greater risk for repeat vertebral augmentation: female sex (AOR=1.24; 95% confidence interval [CI]: 1.10–2.36), advanced age (AOR=1.60; 95% CI: 1.32–2.08), diabetes mellitus (AOR=4.31; 95% CI: 4.05–5.88), cerebrovascular disease (AOR=4.09; 95% CI: 3.44–5.76), dementia (AOR=1.97; 95% CI: 1.69–2.33), blindness or low vision (AOR=3.72; 95% CI: 2.32–3.95), hypertension (AOR=2.58; 95% CI: 2.35–3.47), and hyperlipidemia (AOR=2.09; 95% CI: 1.67–2.22). Patients taking calcium/vitamin D (AOR=2.98; 95% CI: 1.83–3.93), bisphosphonates (AOR=2.11; 95% CI: 1.26–2.61), or calcitonin (AOR=4.59; 95% CI: 3.40–5.77) were less likely to undergo repeat vertebral augmentation; however, those taking steroids (AOR=7.28; 95% CI: 6.32–8.08), acetaminophen (AOR=3.54; 95% CI: 2.75–4.83), or nonsteroidal anti-inflammatory drugs (NSAIDs) (AOR=6.14; 95% CI: 5.08–7.41) were more likely to undergo repeat vertebral augmentation. Conclusion We conclude that the incidence of repeat vertebral augmentation is rather high. An understanding of risk factors predicting repeat vertebral augmentation provides valuable basis to improve health care for geriatric populations. PMID:25848240
[Infantile hemangiomas: the revolution of beta-blockers].
Leaute-Labreze, Christine
2014-12-01
Infantile hemangioma is the consequence of both postnatal vasculogenesis and angiogenesis. Hypoxia appears to play an important role as a contributory factor. Infantile hemangiomas have variable clinical features: superficial, deep or mixed. They can be localized or segmental involving a large skin area. Localized infantile hemangiomas are usually benign, unless they are located near a noble structure (airway orbit...), while segmental infantile hemangioma may be associated with complex underlying birth defects (PHACES and SACRAL syndromes). Clinical follow-up of infants with infantile hemangioma must be particularly careful in the first weeks of life since 80% of all infantile hemangiomas have reached their final size at age 5 months. A majority of infantile hemangiomas are mild and do not required any treatment. Main indications for treatment are: vital risk (heart failure, respiratory distress), functional risk (amblyopia, swallowing disorders...), painful ulceration and disfigurement (face involvement of nose, lips...). Propranolol, has been quickly adopted as the first line medical treatment for complicated infantile hemangioma; and it is the only treatment to have a marketing authorization in this indication. It is recommended to begin the treatment as early as possible before three months of age to minimize the risk of complications and sequelae.

Hemangioma of the rib is an uncommon benign vascular tumour. A case of rib hemangioma in a 29-year-old woman is presented. Chest roentgenogram and computed tomography revealed a mass along the inner surface of the 7th left rib with bone destruction. She underwent resection of the 7th rib. The pathologic diagnosis was cavernous hemangioma. Hemangiomas of the rib are rare tumours but should be kept in mind in the differential diagnosis of rib tumours.

Capillary hemangiomas are benign endothelial cell neoplasms that are believed to be hamartomatous proliferations of vascular endothelial cells. The occurrence of spinal epidural capillary hemangiomas is exceedingly rare. Only 8 epidurally located cases of capillary hemangiomas in the spinal canal have been reported in the literature. We report for the first time, to our knowledge, a case of lumbosacral epidural capillary hemangioma revealed by S1 back pain and radicular pain in a 60-year-old patient, caused by an L5-S1 epidural capillary hemangioma. The neurological symptoms of the patient improved after surgery. Spinal epidural capillary hemangioma is exceedingly rare. These lesions are benign and can mimic dumbbell-shaped neurinoma. Total removal by surgery is curative. Copyright © 2015 Elsevier Masson SAS. All rights reserved.
A rare invasive hemangioma in cauda equina.
Xiang, Hongfei; Shen, Nana; Chen, Bohua; Ma, Xuexiao; Xin, Gang
2017-05-01
Typical hemangioma of cauda equina with relative clear margin has been described in some case reports, but atypical hemangioma with invasion, infiltration, and augmentation of all nerve roots in the cauda equina area has never been reported. In this paper, we reported a rare case with invasive hemangioma in cauda equina, and analyzed its radiological appearance and treatment. We described an atypical case of hemangioma, which was revealed by MR and intraoperative photograph without clear margin and confirmed by histopathologic diagnosis. The patient was received radiotherapy (5400 cGy/25f/5w) and continued to be clinically in good condition with follow-up MR after 24 months without further surgery. Surgery may be the first management modality for hemangiomas with severe or progressive neurologic deficits, and radiotherapy may be an alternative therapy to treat hemangiomas according to accurate histopathologic diagnosis.

Hemangiomas have rarely been found in the spinal cord. A few cases of spinal capillary hemangioma have been reported since 1987. The authors reported the two cases of capillary hemangioma including the tumor at conus medullaris and the another mimicked von Hippel-Lindau disease. A 15-year-old man was presented with coccydynia and left leg pain. A magnetic resonance imaging (MRI) revealed an intradural extramedullary enhancing mass at conus medullaris. Another case, a 31-year-old man was presented with a history of familial history of brain tumor, retinal hemangioma both eyes, multiple pancreatic cyst and syringobulbia with syringohydromyelia. On MRI, a well-circumscribed intramedullary nodule was detected at C5-6 level and multiple subpial nodule along cervicothoracic spinal cord. All patients underwent surgery, and the histological diagnosis confirmed capillary hemangioma. Although rare and indistinguishable from other tumors, capillary hemangioma should be in the differential diagnosis of the spinal cord tumor. PMID:28761543

To study the effectiveness of long segment fixation combined with vertebroplasty (LSF-VP) for severe osteoporotic thoracolumbar compressive fractures with kyphosis deformity. Between March 2006 and May 2012, a retrospective analysis was made on the clinical data of 48 cases of severe osteoporotic thoracolumbar compressive fractures with more than 50% collapse of the anterior vertebral body or more than 400 of sagittal angulation, which were treated by LSF-VP in 27 cases (LSF-VP group) or percutaneous kyphoplasty (PKP) in 21 cases (PKP group). All patients suffered from single thoracolumbar vertebral compressive fracture at T11 to L2. There was no significant difference in gender, age, spinal segment, and T values of bone mineral density between 2 groups (P > 0.05). The effectiveness of the treatment was appraised by visual analogue scale (VAS), Cobb angle of thoracolumbar kyphosis, height of anterior/posterior vertebral body, and compressive ratio of vertebrae before and after operations. The LSF-VP group had longer operation time, hospitalization days, and more bone cement injection volume than the PKP group, showing significant differences (P < 0.05). Intraoperative blood loss in LSF-VP group ranged from 220 to 1,050 mL (mean, 517 mL). No pulmonaryor cerebral embolism or cerebrospinal fluid leakage was found in both groups. Asymptomatic bone cement leakage was found in 3 cases of LSF-VP group and 2 cases of PKP group. The patients were followed up for 16-78 months (mean, 41.1 months) in LSF-VP group, and 12-71 months (mean, 42.1 months) in PKP group. No fixation failure such as loosened or broken pedicle screw was found in LSF-VP group during the follow-up, and no re-fracture or adjacent vertebral body fracture was found. Two cases in PKP group at 39 and 56 months after operation respectively were found to have poor maintenance of vertebral height and loss of rectification (Cobb angle was more than 40 degrees) with recurrence of pain, which were treated by second surgery of LSF-VP; another case had compressive fracture of the adjacent segment and thoracolumbar kyphosis at 16 months after operation, which was treated by second surgery of LSF-VP. There were significant differences in the other indexes between each pair of the three time points (P < 0.05), except the Cobb angle of thoracolumbar kyphosis, and the height of posterior vertebral body between discharge and last follow-up in LSF-VP group, and except the Cobb angle of thoracolumbar kyphosis and compressive ratio of bertebrae between discharge and last follow-up in PKP group (P > 0.05). After operation, the other indexes of LSF-VP group were significantly better than those of PKP group at each time point (P < 0.05), except the VAS score and the height of posterior vertebral body at discharge (P > 0.05). The effectiveness of LSF-VP is satisfactory in treating severe osteoporotic thoracolumbar compressive fractures with kyphosis deformity. LSF-VP can acquire better rectification of kyphosis and recovery of vertebral body height than PKP.

Previously, we reported a case of brainstem cavernous hemangioma showing false positive responses to electromyographic tracheal tube (EMG tube). We concluded that the cause was spontaneous respiration accompanied by vocal cord movement. We report a case of left vertebral artery aneurysm showing evoked potentials on bilateral electrodes by the left vagus nerve stimulation to EMG tube. An 82-year-old woman underwent clipping of a left unruptured vertebral artery-posterior inferior cerebellar artery aneurysm. General anesthesia was induced with remifentanil, propofol and suxamethonium, and was maintained with oxygen, air, remifentanil and propofol. We monitored somatosensory evoked potentials, motor evoked potentials, and electromyogram of the vocal cord. When the manipulation reached brainstem and the instrument touched the left vagus nerve, evoked potentials appeared on bilateral electrodes. EMG tube is equipped with two electrodes on both sides. We concluded that the left vagus nerve stimulation generated evoked potentials of the left laryngeal muscles, and they were simultaneously detected as potential difference between two electrodes on both sides. EMG tube is used to identify the vagus nerve. However, it is necessary to bear in mind that each vagus nerve stimulation inevitably generates evoked potentials on bilateral electrodes.

To study the surgical method to reduce bleeding in treating hemangioma at non-limb sites. From November 1998 to November 2003, 49 cases of non-limb hemangioma were treated, aged 3 months to 63 years, including 21 males and 28 females. There were 14 cases of capillary hemangioma, 25 cases of cavernous hemangioma, 7 cases of arterial racemose angioma and 3 cases of mixture hemangioma. According to the position and type of hemangioma, the various methods of blocking blood vessels were adopted to assist resect tumors. After the pulsatile artery was felt in arterial racemose angioma of neck and face by palpation, we sutured and knotted it with 7-0 silk string to block the bleeding. We found out the common iliac artery or external iliac artery or femoral artery and blocked them temporarily to resect arterial racemose angioma in inguen and thigh. We sutured and knotted vessel with 7-0 silk string to block the bleeding in capillary hemangioma and cavernous hemangioma of neck and face and truncus. Intraoperative bleeding obviously decreased and the tumor size reduced to various extent. Of the 49 cases, 47 cases achieved complete success, 2 cases bled within two days after operation. A postoperative follow-up of 6 months to 4 years showed that the appearance and function were satisfactory. The preoperative method of blocking blood vessels obviously can reduce intraoperative bleeding and decrease operative difficulty, which makes it possible to eradicate hemangioma and lower recurrence rate.

Optical coherence tomography angiography (OCTA) allows visualization of iris racemose hemangioma course and its relation to the normal iris microvasculature. To describe OCTA features of iris racemose hemangioma. Descriptive, noncomparative case series at a tertiary referral center (Ocular Oncology Service of Wills Eye Hospital). Patients diagnosed with unilateral iris racemose hemangioma were included in the study. Features of iris racemose hemangioma on OCTA. Four eyes of 4 patients with unilateral iris racemose hemangioma were included in the study. Mean patient age was 50 years, all patients were white, and Snellen visual acuity was 20/20 in each case. All eyes had sectoral iris racemose hemangioma without associated iris or ciliary body solid tumor on clinical examination and ultrasound biomicroscopy. By anterior segment OCT, the racemose hemangioma was partially visualized in all cases. By OCTA, the hemangioma was clearly visualized as a uniform large-caliber vascular tortuous loop with intense flow characteristics superimposed over small-caliber radial iris vessels against a background of low-signal iris stroma. The vascular course on OCTA resembled a light bulb filament (filament sign), arising from the peripheral iris (base of light bulb) and forming a tortuous loop on reaching its peak (midfilament) near the pupil (n = 3) or midzonal iris (n = 1), before returning to the peripheral iris (base of light bulb). Intravenous fluorescein angiography performed in 1 eye depicted the iris hemangioma; however, small-caliber radial iris vessels were more distinct on OCTA than intravenous fluorescein angiography. Optical coherence tomography angiography is a noninvasive vascular imaging modality that clearly depicts the looping course of iris racemose hemangioma. Optical coherence tomography angiography depicted fine details of radial iris vessels, not distinct on intravenous fluorescein angiography.

A mathematical model of a three-vertebra complex was developed in order to make an exact calculation of loss of supporting ability of the vertebral column in trauma. Mathematical description of the dynamic processes was based on Lagrange differential equation of the second order. The degree of compression and instability of the three-vertebra complex, established using mathematical modeling, determines the decision on the surgical treatment and might be considered as a prognostic criterion of the course of the compression trauma of the spine. The method of mathematical modeling of supporting ability of the vertebral column was used in 72 patients.

To elucidate the mechanisms and prognosis of rotational vertebral artery occlusion (RVAO). We analyzed clinical and radiological characteristics, patterns of induced nystagmus, and outcome in 21 patients (13 men, aged 29-77 years) with RVAO documented by dynamic cerebral angiography during an 8-year period at 3 University Hospitals in Korea. The follow-up periods ranged from 5 to 91 months (median, 37.5 months). Most patients (n=19; 90.5%) received conservative treatments. All the patients developed vertigo accompanied by tinnitus (38%), fainting (24%), or blurred vision (19%). Only 12 (57.1%) patients showed the typical pattern of RVAO during dynamic cerebral angiography, a compression of the dominant vertebral artery at the C1-2 level during contralateral head rotation. The induced nystagmus was mostly downbeat with horizontal and torsional components beating toward the compressed vertebral artery side. None of the patients with conservative treatments developed posterior circulation stroke, and 4 of them (21.1%) showed resolution of symptoms during the follow-ups. RVAO has various patterns of vertebral artery compression, and favorable long-term outcome with conservative treatments. In most patients with RVAO, the symptoms may be ascribed to asymmetrical excitation of the bilateral labyrinth induced by transient ischemia or by disinhibition from inferior cerebellar hypoperfusion. Conservative management might be considered as the first-line treatment of RVAO.

Objective To characterize and compare the MRI morphological features of the cervical vertebral column of Great Danes with and without clinical signs of cervical spondylomyelopathy (CSM). Design Prospective cohort study. Animals 30 Great Danes (15 clinically normal and 15 CSM-affected). Procedures All dogs underwent MRI of the cervical vertebral column (C2–3 through T1–2). Features evaluated included sites of subarachnoid space compression, spinal cord compression, or both; degree, cause, and direction of compression; MRI signal changes of the spinal cord; articular process (facet) joint characteristics; internal vertebral venous plexus visibility; and presence of extradural synovial cysts as well as presence and degree of intervertebral disk degeneration and foraminal stenosis. Results Clinically normal and CSM-affected dogs had 11 and 61 compressive sites, respectively, detected with MRI. All CSM-affected dogs had ≥ 1 site of spinal cord compression. No signal changes were observed in spinal cords of normal dogs, whereas 14 sites of hyperintensity were found in 9 CSM-affected dogs. Foraminal stenosis was present in 11 clinically normal and all CSM-affected dogs. The number of stenotic foraminal sites was significantly greater in the CSM-affected group, and severe stenosis appeared to be more common in this group than in the clinically normal group. Significant differences were identified between clinically normal and CSM-affected dogs with regard to amount of synovial fluid evident, regularity of articular surfaces, degree of articular process joint proliferation, and internal vertebral venous plexus visibility. Conclusions and Clinical Relevance Abnormalities were detected with MRI in several clinically normal Great Danes. Severe spinal cord compression, number of stenotic foraminal sites, and signal changes within the spinal cord distinguished CSM-affected from clinically normal Great Danes. PMID:25075822

To analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures. From October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation. All operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases. It's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

Infra-red diode laser with wavelength 1060 nm was used for combined treatment of 163 children aged from 21 days to 13 years with 221 hemangiomas. For interstitial coagulation a power of 1.8-2 W and a power density of 5-90 J/cm3 were used in continuous mode. For distant coagulation pulse mode was applied with pulse/pause duration 30-50/200-250 ms, average power 1.3-2 W, and power density 65-450 J/cm2. 197 (89.1 %) hemangiomas were capillary, 7 (3.2 %) cavernous, and 17 (7.7 %) combined (combination of capillary and cavernous hemangiomas). The area of hemangiomas ranged from 6 mm2 to 48 cm2. For the majority (193, 87.3 %) of hemangiomas one session of photocoagulation was enough to achieve a good cosmetic effect. However, 28 (12.7 %) hemangiomas were treated repeatedly, 11 (5%) of them needed 4-7 sessions. In 8 children with cavernous and combined hemangiomas both distant and interstitial laser coagulation were used. In all, good or excellent results were obtained in 96,3 % of the patients. In 6 (3.7%) patients with extensive combined hematomas the considerable improvement was achieved.

Recent studies have shown that radiofrequency (RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.

Epithelioid hemangioma is a rare and benign vascular tumor, most often occurring in the skin. Numerous other localizations, including bones, have been reported. The overall favorable clinical outcome of cutaneous epithelioid hemangioma is now well documented, but it still remains debated in osseous localization, as local recurrences and metastases have been described. We report a case of epithelioid hemangioma of the spine occurring in a 25-year-old male, and discuss main differential diagnoses. Recent studies tend to demonstrate that osseous epithelioid hemangioma, as cutaneous epithelioid hemangioma, should be considered as a benign tumor. Histologically, epithelioid hemangioma consists of a vascular proliferation with diffuse or lobular pattern and features vascular spaces lined by epitheliod endothelial cells with numerous lymphocytes and eosinophils. The main differential diagnosis is represented by epithelioid hemangioendothelioma, the surgical treatment of which must be more aggressive. Precise histological diagnosis is essential for accurate clinical management and to avoid overtreatment. Copyright © 2011. Published by Elsevier Masson SAS.

The occurrence of intradural extramedullary capillary hemangiomas is exceedingly rare. To date, only 39 cases of intradural extramedullary capillary hemangiomas have been reported in the English literature, and all of these cases have been described at the lumbar and thoracic spinal levels. To our knowledge, this report is the first case of capillary hemangiomas of the cervical spine in the literature. In general, this entity is misdiagnosed preoperatively as a neoplasm. A 29-year-old man presented with neck pain and progressive gait disturbance, and was diagnosed with an intradural extramedullary capillary hemangioma in the cervical region. Although rare, our case demonstrates that capillary hemangioma should be considered in the differential diagnosis of intradural extramedullary tumor of the cervical spine.

1. Any hemangioma that involves the upper or lower lid and leads to partial closure in infancy may interfere with or prevent development of normal binocular vision in a matter of days to weeks. 2. Hemangiomas least likely to interfere with vision are lower lid lesions occupying one third of the lid margin or less, not extending beyond the eyelid region, and resolving early. 3. Hemangiomas associated with deprivation amblyopia (with or without anisometropia) are lesions occupying more than one half of the lid margin, extending beyond the eyelid region, resolving late, and obstructing the visual axis. 4. Hemangiomas associated with isolated anisometropic amblyopia are local but bulky lesions that are usually but not always restricted to the upper lid, closing the eye partly and resolving late. 5. The treatment of choice for periorbital hemangiomas is corticosteroids, either systemic or intralesional.

Capillary hemangioma is the most common benign tumor of eyelids and orbit in children. Recently, a topical beta blocker has been reported as an effective treatment for superficial capillary hemangiomas. We present a case report of two children having large capillary hemangiomas who responded well to topical treatment by 0.5% timolol maleate solution. After 12 months of treatment, the lesion has significantly reduced in size, thickness, and color in both cases. Thus, we conclude that long-term use of topical 0.5% timolol maleate solution is safe and effective in treating superficial capillary hemangiomas.

Hemangiomas are rarely found in the heart and pericardial involvement is even more rare. We report a case of primary pericardial hemangioma, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images. Our case also highlights the importance of systematic cropping of the 3D datasets in making a diagnosis of pericardial hemangioma with a greater degree of certainty. In addition, we also provide a literature review of the features of cardiac/pericardial hemangiomas in a tabular form. © 2017, Wiley Periodicals, Inc.

Airway hemangiomas can be difficult to manage and cause anxiety in both the parents and the treating physician. Propranolol, a nonselective beta-blocker, has recently been used for treating proliferating infantile hemangiomas. We report successful management of a proliferating, large, mixed infantile hemangioma with subglottic extension in an Indian infant using oral propranolol in a dose of 2mg/kg/day without any side effects. Induction of early involution and freedom from the side effects of steroid therapy seem encouraging for using propranolol as a first line treatment modality in the management of troublesome hemangiomas. © 2013 The International Society of Dermatology.

Spontaneous rupture of hepatic hemangiomas: A review of the literature.
Ribeiro, Marcelo Af; Papaiordanou, Francine; Gonçalves, Juliana M; Chaib, Eleazar

Hepatic hemangiomas are congenital vascular malformations, considered the most common benign mesenchymal hepatic tumors, composed of masses of blood vessels that are atypical or irregular in arrangement and size. Hepatic hemangiomas can be divided into two major groups: capillary hemangiomas and cavernous hemangiomas These tumors most frequently affect females (80%) and adults in their fourth and fifth decades of life. Most cases are asymptomatic although a few patients may present with a wide variety of clinical symptoms, with spontaneous or traumatic rupture being the most severe complication. In cases of spontaneous rupture, clinical manifestations consist of sudden abdominal pain, and anemia secondary to a haemoperitoneum. Disseminated intravascular coagulopathy can also occur. Haemodynamic instability and signs of hypovolemic shock appear in about one third of cases. As the size of the hemangioma increases, so does the chance of rupture. Imaging studies used in the diagnosis of hepatic hemangiomas include ultrasonography, dynamic contrast-enchanced computed tomography scanning, magnetic resonance imaging, hepatic arteriography, digital subtraction angiography, and nuclear medicine studies. In most cases hepatic hemangiomas are asymptomatic and should be followed up by means of periodic radiological examination. Surgery should be restricted to specific situations. Absolute indications for surgery are spontaneous or traumatic rupture with hemoperitoneum, intratumoral bleeding and consumptive coagulopathy (Kassabach-Merrit syndrome). In a patient presenting with acute abdominal pain due to unknown abdominal disease, spontaneous rupture of a hepatic tumor such as a hemangioma should be considered as a rare differential diagnosis.

Finite element models of an isolated vertebral body cannot accurately predict compressive strength of the spinal column because, in life, compressive load is variably distributed across the vertebral body and neural arch. The purpose of this study was to develop and validate a patient-specific finite element model of a functional spinal unit, and then use the model to predict vertebral strength from medical images. A total of 16 cadaveric functional spinal units were scanned and then tested mechanically in bending and compression to generate a vertebral wedge fracture. Before testing, an image processing and finite element analysis framework (SpineVox-Pro), developed previously in MATLAB using ANSYS APDL, was used to generate a subject-specific finite element model with eight-node hexahedral elements. Transversely isotropic linear-elastic material properties were assigned to vertebrae, and simple homogeneous linear-elastic properties were assigned to the intervertebral disc. Forward bending loading conditions were applied to simulate manual handling. Results showed that vertebral strengths measured by experiment were positively correlated with strengths predicted by the functional spinal unit finite element model with von Mises or Drucker-Prager failure criteria ( R 2 = 0.80-0.87), with areal bone mineral density measured by dual-energy X-ray absorptiometry ( R 2 = 0.54) and with volumetric bone mineral density from quantitative computed tomography ( R 2 = 0.79). Large-displacement non-linear analyses on all specimens did not improve predictions. We conclude that subject-specific finite element models of a functional spinal unit have potential to estimate the vertebral strength better than bone mineral density alone.

Capillary hemangiomas are frequently encountered superficially in the cutaneous, subcutaneous, or mucosal tissues during the childhood and early adulthood, but the occurrence of spinal intradural capillary hemangioma is relatively rare. Herein, we report a case with capillary hemangioma of the thoracic spine. MR and PET/CT features of this lesion are presented, and awareness of this entity may help differentiate it from other spinal intradural tumors.

Extradural hemangiomas are rare, have varied and challenging clinical presentations, and require special considerations from the management point of view. A 70-year-old female presented with back pain that was ultimately attributed to a thoracolumbar extra-dural "dumbbell" hemangioma. Following surgical resection, the patient did well. Extradural hemangiomas may present as spinal extradural soft tissue masses that must be differentiated from dumbbell neurofibroma.

To observe different bone cement dispersion types of PVP, PKP and manipulative reduction PVP and their effects in the treatment of senile osteoporotic vertebral compression fractures and the bone cement leakage rate. The clinical data of patients with osteoporotic vertebral compression fractures who underwent unilateral vertebroplasty from January 2012 to January 2015 was retrospectively analyzed. Of them, 56 cases including 22 males and 34 females aged from 60 to 78 years old were treated by PVP operation; Fouty-eight cases including 17 males and 31 females aged from 61 to 79 years old were treated by PKP operation; Forty-three cases including 15 males and 28 females aged from 60 to 76 years old were treated by manipulative reduction PVP operation. AP and lateral DR films were taken after the operation; the vertebral bone cement diffusion district area and mass district area were calculated with AutoCAD graphics processing software by AP and lateral DR picture, then ratio(K) of average diffusion area and mass area were calculated, defining K<50% as mass type, 50%<=K<=100% as mixed type and K>100% as diffusion type. Different bone cement dispersion types of PVP, PKP and manipulative reduction PVP operation were analyzed. According to bone cement dispersion types, patients were divided into diffusion type, mixed type and mass type groups.Visual analogue scale (VAS), vertebral body compression rate, JOA score and bone cement leakage rate were observed. All patients were followed up for 12-24 months with an average of 17.2 months. There was significant difference in bone cement dispersion type among three groups ( P <0.05). The constituent ratio of diffusion type, mixed type and mass type in PVP operation was 46.43%, 35.71%, 17.86%, in PKP was 16.67%, 37.50% , 45.83%, and in manipulative reduction PVP was 37.21%, 44.19% and 18.60%, respectively. PVP operation and manipulative reduction PVP were mainly composed of diffusion type and mixed type, while PKP was mainly composed of mass type and mixed type. There was no significant difference in VAS score, JOA score and bone cement leakage rate among three groups. There was statistically significant difference in postoperative vertebral body compression rate among three bone cement dispersion types( P <0.05), postoperative vertebral body compression rate in diffusion type group at 24 h postoperatively and final follow-up was (17.31±5.06)% and(18.58±4.91)%, respectively. In mixed type group, it was(14.21±5.15)% and(14.59±5.07)%, respectively. In mass type group, it was(13.89±5.02)% and(14.28±4.94)%, respectively. Bone cement dispersion type is different in PVP, PKP and manipulative reduction PVP operation. The bone cement dispersion of mass type and mixed type to recovery of compressed vertebral body is better than diffusion type, and there is no obvious difference in clinical effect in different bone cement dispersion type early and middle term.

PurposeWe aim to determine the predictors of new adjacent vertebral fractures (AVCFs) after percutaneous vertebroplasty (PVP) in patients with osteoporotic vertebral compression fractures (OVCFs) and to construct a risk prediction score to estimate a 2-year new AVCF risk-by-risk factor condition.Materials and MethodsPatients with OVCFs who underwent their first PVP between December 2006 and December 2013 at Hospital A (training cohort) and Hospital B (validation cohort) were included in this study. In training cohort, we assessed the independent risk predictors and developed the probability of new adjacent OVCFs (PNAV) score system using the Cox proportional hazard regression analysis. The accuracy ofmore » this system was then validated in both training and validation cohorts by concordance (c) statistic.Results421 patients (training cohort: n = 256; validation cohort: n = 165) were included in this study. In training cohort, new AVCFs after the first PVP treatment occurred in 33 (12.9%) patients. The independent risk factors were intradiscal cement leakage and preexisting old vertebral compression fracture(s). The estimated 2-year absolute risk of new AVCFs ranged from less than 4% in patients with neither independent risk factors to more than 45% in individuals with both factors.ConclusionsThe PNAV score is an objective and easy approach to predict the risk of new AVCFs.« less
A finite element evaluation of the moment arm hypothesis for altered vertebral shear failure force.
Howarth, Samuel J; Karakolis, Thomas; Callaghan, Jack P
2015-01-01
The mechanism of vertebral shear failure is likely a bending moment generated about the pars interarticularis by facet contact, and the moment arm length (MAL) between the centroid of facet contact and the location of pars interarticularis failure has been hypothesised to be an influential modulator of shear failure force. To quantitatively evaluate this hypothesis, anterior shear of C3 over C4 was simulated in a finite element model of the porcine C3-C4 vertebral joint with each combination of five compressive force magnitudes (0-60% of estimated compressive failure force) and three postures (flexed, neutral and extended). Bilateral locations of peak stress within C3's pars interarticularis were identified along with the centroids of contact force on the inferior facets. These measurements were used to calculate the MAL of facet contact force. Changes in MAL were also related to shear failure forces measured from similar in vitro tests. Flexed and extended vertebral postures respectively increased and decreased the MAL by 6.6% and 4.8%. The MAL decreased by only 2.6% from the smallest to the largest compressive force. Furthermore, altered MAL explained 70% of the variance in measured shear failure force from comparable in vitro testing with larger MALs being associated with lower shear failure forces. Our results confirmed that the MAL is indeed a significant modulator of vertebral shear failure force. Considering spine flexion is necessary when assessing low-back shear injury potential because of the association between altered facet articulation and lower vertebral shear failure tolerance.

The treatment of osteoporotic vertebral compression fractures using transpedicular cement augmentation has grown significantly during the past two decades. Balloon kyphoplasty was developed to restore vertebral height and improve sagittal alignment. Several studies have shown these theoretical improvements cannot be transferred universally to the clinical setting. The aim of the current study is to evaluate two different procedures used for percutaneous augmentation of vertebral compression fractures with respect to height restoration: balloon kyphoplasty and SpineJack. Twenty-four vertebral bodies of two intact, fresh human cadaveric spines (T6-L5; donor age, 70 years and 60 years; T-score -6.8 points and -6.3 points) were scanned using computed tomography (CT) and dissected into single vertebral bodies. Vertebral wedge compression fractures were created by a material testing machine (Universal testing machine, Instron 5566, Darmstadt, Germany). The axial load was increased continuously until the height of the anterior edge of the vertebral body was reduced by 40% of the initial measured values. After 15 minutes, the load was decreased manually to 100 N. After postfracture CT, the clamped vertebral bodies were placed in a custom-made loading frame with a preload of 100 N. Twelve vertebral bodies were treated using SpineJack (SJ; Vexim, Balma, France), the 12 remaining vertebral bodies were treated with balloon kyphoplasty (BKP; Kyphon, Medtronic, Sunnyvale, CA, USA). The load was maintained during the procedure until the cement set completely. Posttreatment CT was performed. Anterior, central, and posterior height as well as the Beck index were measured prefracture and postfracture as well as after treatment. For anterior height restoration (BKP, 0.14±1.48 mm; SJ, 3.34±1.19 mm), central height restoration (BKP, 0.91±1.04 mm; SJ, 3.24±1.22 mm), and posterior restoration (BKP, 0.37±0.57 mm; SJ, 1.26±1.05), as well as the Beck index (BKP, 0.00±0.06 mm; SJ, 0.10±0.06), the values for the SpineJack group were significantly higher (p<.05) CONCLUSION: The protocols for creating wedge fractures and using the instrumentation under a constant preload of 100 N led to reproducible results and effects. The study showed that height restoration was significantly better in the SpineJack group compared with the balloon kyphoplasty group. The clinical implications include a better restoration of the sagittal balance of the spine and a reduction of the kyphotic deformity, which may relate to clinical outcome and the biological healing process.

Vertebral augmentation procedures are widely used to treat osteoporotic vertebral compression fractures (VCFs). We report our initial experience with radiofrequency-targeted vertebral augmentation (RF-TVA) in 20 patients aged 50 to 90 years with single-level, symptomatic osteoporotic VCF between T10 and L5, back pain severity > 4 on a 0 to 10 scale, Oswestry Disability Index ≥ 21%, 20% to 90% vertebral height loss compared to adjacent vertebral body, and fracture age < 6 months. After treatment, patients were followed through hospital discharge and returned for visits after 1 week, 1 month, and 3 months. Back pain severity improved 66% (P < 0.001), from 7.9 (95% CI: 7.1 to 8.6) at pretreatment to 2.7 (95% CI: 1.5 to 4.0) at 3 months. Back function improved 46% (P < 0.001), from 74 (95% CI: 69% to 79%) at pretreatment to 40 (95% CI: 33% to 47%) at 3 months. The percentage of patients regularly consuming pain medication was 70% at pretreatment and only 21% at 3 months. No adverse events related to the device or procedure were reported. RF-TVA reduces back pain severity, improves back function, and reduces pain medication requirements with no observed complications in patients with osteoporotic VCF. PMID:24228187
Congenital hemangioma in spondylocostal dysostosis: a novel association*
Salinas-Torres, Victor Michael
2016-01-01
Congenital hemangioma is a benign tumor caused by dysfunction in embryogenesis and vasculogenesis, which progresses during fetal life to manifest as fully developed at birth. Although hemangiomas are the most common tumor of infancy, rapidly involuting congenital hemangioma has not been described in spondylocostal dysostosis. I report the novel association of congenital hemangioma and spondylocostal dysostosis in a Mexican newborn female patient with neural tube defects. Given the embryological relationship between skin and nervous system, I surmise that this association is not coincidental. I also propose that these morphologic alterations be incorporated to the spondylocostal dysostosis phenotype and specifically looked for in other affected children, in order to provide appropriate medical management and genetic counseling.

A retrospective study. The aim of this study was the evaluation of the safety and effectiveness of radiofrequency-targeted vertebral augmentation (RF-TVA) in comparison with balloon kyphoplasty (BK) for the treatment of acute painful vertebral compression fractures (VCFs) on the basis of matched pairs. Vertebroplasty and BK are the common surgical interventions for the treatment of VCF. Both are effective and safe but pose some risks such as adjacent fractures and cement leakage. In 2009, RF-TVA was introduced as an innovative augmentation procedure for the treatment of VCF. A total of 192 patients (116 female; 51-90 y) with VCF (n=303) at 1 to 3 levels were treated with RF-TVA or BK. Functionality (Oswestry Disability Index), pain (visual analogue scale), vertebral height (anterior, middle), and kyphotic angle were evaluated over a 2-year period (postoperatively, 3-4 d, 3, 6, 12, and 24 mo). In addition, operating time and occurrence of cement leakage were recorded. Pain and functionality were significantly improved after both treatments. In both groups, there was an increase in the vertebral height and a decrease in the kyphotic angle, which remained relatively consistent during 24 months. The incidence of cement leakage was 9.4% (n=9) in the RF-TVA group and 24.0% (n=25) in the BK group. The mean operating time with radiofrequency kyphoplasty was 25.9±9.9 minutes, and with balloon kyphoplasty 48.0±18.4 minutes. RF-TVA is a safe and effective procedure for the treatment of vertebral compression fractures when compared with BK. Improvement in pain and functional scores after RF-TVA are durable through 24 months postprocedure and remained better than those after BK at long-term follow-up. Operating time for RF-TVA is shorter and the risk of cement leakage is lower. Both procedures provided similar results in vertebral height restoration and reduction in the kyphotic angle.

Highlights: • PEDF was expressed and induced during the involuting phase of IH. • PEDF inhibited the cell growth of the involuting HemECs in an autocrine manner. • PEDF suppression restored the impaired cell growth of the involuting HemECs. - Abstract: Hemangioma is a benign tumor derived from abnormal blood vessel growth. Unlike other vascular tumor counterparts, a hemangioma is known to proliferate during its early stage but it is followed by a stage of involution where regression of the tumor occurs. The critical onset leading to the involution of hemangioma is currently not well understood. This study focused onmore » the molecular identities of the involution of hemangioma. We demonstrated that a soluble factor released from the involuting phase of hemangioma-derived endothelial cells (HemECs) and identified pigment epithelium-derived factor (PEDF) as an anti-angiogenic factor that was associated with the growth inhibition of the involuting HemECs. The growth inhibition of the involuting HemECs was reversed by suppression of PEDF in the involuting HemECs. Furthermore, we found that PEDF was more up-regulated in the involuting phase of hemangioma tissues than in the proliferating or the involuted. Taken together, we propose that PEDF accelerates the involution of hemangioma by growth inhibition of HemECs in an autocrine manner. The regulatory mechanism of PEDF expression could be a potential therapeutic target to treat hemangiomas.« less
Inhibition of hemangioma growth using polymer-lipid hybrid nanoparticles for delivery of rapamycin.

Although infantile hemangiomas is benign, its rapid growth may induce serious complications. However, only one drug Hemangeol™ has been approved by US Food and Drug Administration (FDA) to treat infantile hemangiomas. Thus it is necessary to develop novel alternative drugs to treat infantile hemangiomas. Rapamycin is a well-know potent antiangiogenic agent, whereas the daily oral administration of rapamycin exerts undesired metabolic effects due to its inhibition of mechanistic target of rapamycin (mTOR) which is critical in cell metabolism. We hereby developed rapamycin-loaded polymer-lipid hybrid nanoparticles (Rapamycin-PLNPs) as a local controlled release system to realize local and sustained release of rapamycin, aiming to reduce the side effects and frequency of administration of rapamycin. Rapamycin-PLNPs are of a small size (129.1nm), desired drug encapsulation efficiency (63.7%), and sustained drug release for 5 days. Rapamycin-PLNPs were shown to be able to effectively bind to hemangioma endothelia cells (HemECs), induce significant proliferation inhibition and reduce expression of angiogenesis factors in HemECs. The therapeutic effect of Rapamycin-PLNPs against infantile hemangioma in vivo was superior to rapamycin, as reflected by reduced hemangioma volume, weight and microvessel density. Taken together, Rapamycin-PLNPs represent a very promising local approach in the treatment of infantile hemangiomas. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Background: Capillary hemangiomas are benign vascular tumors that rarely occur in the neuraxis. When encountered in the spine, prompt diagnosis and complete resection is crucial. On rare instances, these lesions can acutely hemorrhage, leading to sudden neurological decline. To date, there are only 16 reported cases of intradural capillary hemangiomas in the cauda equina. Case Description: We report a case of an intradural extramedullary cauda equina capillary hemangioma that resulted in back pain and lower extremity motor deficit. Initial magnetic resonance (MR) imaging demonstrated a bilobular intradural L3-4 cauda equina lesion. The lesion was isointense on T1-weighted imaging, mildly hyperintense on T2-weighted images and avidly enhancing after gadolinium administration. Pathology confirmed the diagnosis of capillary hemangioma. Conclusion: Early diagnosis and treatment of this patient resulted in complete resection of the tumor and return of lower extremity motor function. Capillary hemangiomas should be considered in the differential diagnosis of cauda equina lesions. En bloc resection of these lesions is the mainstay of treatment. PMID:25949855

Lytic spinal lesions reduce vertebral strength and may result in their fracture. Vertebral augmentation is employed clinically to provide mechanical stability and pain relief for vertebrae with lytic lesions. However, little is known about its efficacy in strengthening fractured vertebrae containing lytic metastasis. Eighteen unembalmed human lumbar vertebrae, having simulated uncontained lytic defects and tested to failure in a prior study, were augmented using a transpedicular approach and re-tested to failure using a wedge fracture model. Axial and moment based strength and stiffness parameters were used to quantify the effect of augmentation on the structural response of the failed vertebrae. Effects of cement volume, bone mineral density and vertebral geometry on the change in structural response were investigated. Augmentation increased the failed lytic vertebral strength [compression: 85% (P<0.001), flexion: 80% (P<0.001), anterior-posterior shear: 95%, P<0.001)] and stiffness [(40% (P<0.05), 53% (P<0.05), 45% (P<0.05)]. Cement volume correlated with the compressive strength (r(2)=0.47, P<0.05) and anterior-posterior shear strength (r(2)=0.52, P<0.05) and stiffness (r(2)=0.45, P<0.05). Neither the geometry of the failed vertebrae nor its pre-fracture bone mineral density correlated with the volume of cement. Vertebral augmentation is effective in bolstering the failed lytic vertebrae compressive and axial structural competence, showing strength estimates up to 50-90% of historical values of osteoporotic vertebrae without lytic defects. This modest increase suggests that lytic vertebrae undergo a high degree of structural damage at failure, with strength only partially restored by vertebral augmentation. The positive effect of cement volume is self-limiting due to extravasation. Copyright © 2015. Published by Elsevier Ltd.

The authors describe the case of a 48-year-old man found to have the first reported intramedullary spinal cord spindle cell hemangioma. Previous research indicates that spindle cell hemangiomas are rarely found in the spine. Only 3 previous cases exist, all in the intradural, extramedullary space. In the present case, gross-total resection of the tumor was possible with no loss of function from baseline. This report presents the successful resection of the first reported intramedullary spindle cell hemangioma and reports 4-month follow-up, demonstrating the biological behavior of this rare tumor.

Primary intraosseous hemangiomas are rare (0.7% of all osseous neoplasms), benign, slow-growing neoplasms. These lesions are usually solitary. We are reporting a case of multicentric intraosseous hemangiomas. Investigation, treatment options, and role of N-butylcyanoacrylate (NBCA) in management will be discussed. A 20-year-old man had multicentric intraosseous hemangiomas involving the skull bones, mandible, vertebra, pelvic bone, and tibial tuberosity. N-butylcyanoacrylate was used by direct puncture technique using a transosseous transcutaneous route to control profuse bleeding from the retromolar region. To the best of our knowledge, this is the first reported case with such extensive multicentric intraosseous hemangiomas. N-butylcyanoacrylate by direct puncture technique can be an effective method to devascularize and stabilize low-flow intraosseous vascular tumors. (c) 2007 Wiley Periodicals, Inc.
[Hemangiomas and vascular malformations of the head and neck].
Hassmann-Poznańska, Elibieta; Kurzyna, Agnieszka
2006-01-01
This paper presents the review of current knowledge regarding vascular lesions of the head and neck. For many years the term hemangioma was used to describe all vascular lesions. Mulliken and Glowacki classified congenital vascular lesions and recognized two distinct entities, hemangiomas-vascular tumors and vascular malformations. Hemangiomas are usually not present at birth, proliferate during first year of life and then involute. They are composed of proliferating endothelial cells. Vascular malformations are always present at birth although not always apparent, increase slowly in size throughout whole life and never involute. They enlarge by hypertrophy of malformed vessels. Vascular malformations can be further subdivided according to the type of involved vessels as arterial, arteriovenous, venous, capillary or lymphatic. Accurate diagnosis of hemangiomas and vascular malformations remains a challenge for physicians. Although majority of hemangiomas are self limiting lesions some of them may develop complications such as; ulceration, airway obstruction, ophthalmic complications, psychosocial consequences. Segmental hemangiomas are associated with the risk of structural anomalies such as those that occur in PHACE syndrome. Clinical presentation and forms of treatment of various forms of vascular malformations are presented. Vascular malformations have to be treated according to their histopathology and location, as well as their hemodynamic features shown by radiological examinations.

To investigate the use of diffusion weighted magnetic resonance imaging (DWI) and the apparent diffusion coefficient (ADC) values in the diagnosis of hemangioma. The study population consisted of 72 patients with liver masses larger than 1 cm (72 focal lesions). DWI examination with a b value of 600 s/mm2 was carried out for all patients. After DWI examination, an ADC map was created and ADC values were measured for 72 liver masses and normal liver tissue (control group). The average ADC values of normal liver tissue and focal liver lesions, the "cut-off" ADC values, and the diagnostic sensitivity and specificity of the ADC map in diagnosing hemangioma, benign and malignant lesions were researched. Of the 72 liver masses, 51 were benign and 21 were malignant. Benign lesions comprised 38 hemangiomas and 13 simple cysts. Malignant lesions comprised 9 hepatocellular carcinomas, and 12 metastases. The highest ADC values were measured for cysts (3.782±0.53×10(-3) mm(2)/s) and hemangiomas (2.705±0.63×10(-3) mm(2)/s). The average ADC value of hemangiomas was significantly higher than malignant lesions and the normal control group (p<0.001). The average ADC value of cysts were significantly higher when compared to hemangiomas and normal control group (p<0.001). To distinguish hemangiomas from malignant liver lesions, the "cut-off" ADC value of 1.800×10(-3) mm(2)/s had a sensitivity of 97.4% and a specificity of 90.9%. To distinguish hemangioma from normal liver parenchyma the "cut-off" value of 1.858×10(-3) mm(2)/s had a sensitivity of 97.4% and a specificity of 95.7%. To distinguish benign liver lesions from malignant liver lesions the "cut-off" value of 1.800×10(-3) mm(2)/s had a sensitivity of 96.1% and a specificity of 90.0%. DWI and quantitative measurement of ADC values can be used in differential diagnosis of benign and malignant liver lesions and also in the diagnosis and differentiation of hemangiomas. When dynamic examination cannot distinguish cases with vascular metastasis and lesions from hemangioma, DWI and ADC values can be useful in the primary diagnosis and differential diagnosis. The technique does not require contrast material, so it can safely be used in patients with renal failure.

The primary objective of the present prospective study was to compare the diagnostic performance of conventional radiography (CR) and whole-body low-dose computed tomography (WBLDCT) with a comparable radiation dose reconstructed using hybrid iterative reconstruction technique, in terms of the detection of bone lesions, skeletal fractures, vertebral compressions and extraskeletal findings. The secondary objective was to evaluate lesion attenuation in relation to its size. A total of 74 patients underwent same-day skeletal survey by CR and WBLDCT. In CR and WBLDCT, two readers assessed the number of osteolytic lesions at each region and stage according to the International Myeloma Working Group (IMWG) criteria. A single reader additionally assessed extraskeletal findings and their significance, the number of vertebral compressions and bone fractures. The radiation exposure was 2.7±0.9 mSv for WBLDCT and 2.5±0.9 mSv for CR (P=0.054). CR detected bone involvement in 127 out of 486 regions (26%; P<0.0001), confirmed by WBLDCT. CR underestimated the disease stage in 16% and overestimated it in 8% of the patients (P=0.0077). WBLDCT detected more rib fractures compared with CR (188 vs. 47; P<0.0001), vertebral compressions (93 vs. 67; P=0.010) and extraskeletal findings (194 vs. 52; P<0.0001). There was no correlation observed between lesion size (≥5 mm) and its attenuation (r=-0.006; P=0.93). The inter-observer agreement for the presence of osteolytic lesions was κ=0.76 for WBLDCT, and κ=0.55 for CR. The present study concluded that WBLDCT with hybrid iterative reconstruction technique demonstrates superiority to CR with an identical radiation dose in the detection of bone lesions, skeletal fractures, vertebral compressions and extraskeletal findings, which results in up- or downstaging in 24% patients according to the IMWG criteria. The attenuation of osteolytic lesions can be measured with the avoidance of the partial volume effect.

Soft tissue hemangiomas are commonly encountered lesions, accounting for 7-10 % of all benign soft tissue masses (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010). While the literature describes the great majority of hemangiomas as asymptomatic and discovered only as incidental findings, they do have the potential to induce reactive changes in neighboring structures (Pastushyn et al. Surg Neurol 50(6):535-47, 1998). When these variants occur in close proximity to bone, they may elicit a number of well-documented reactive changes in osseous tissue (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010; DeFilippo et al. Skelet Radiol 25(2):174-7, 1996; Ly et al. AJR Am J Roentgenol 180(6):1695-700, 2003; Sung et al. Skelet Radiol 27(4):205-10, 1998). However, instances of direct extension into bone by soft tissue hemangiomas--that is, infiltration of the mass's vascular components into nearby osseous tissue--are currently undocumented in the literature. In these cases, imaging plays an important role in differentiating hemangiomas from malignant lesions (Mitsionis et al. J Foot Ankle Surg 16(2):27-9, 2010; Sung et al. Skelet Radiol 27(4):205-10, 1998; Pourbagher, Br J Radiol 84(1008):1100-8, 2011). In this article, we present such a case that involved the sacral spine. Imaging revealed a soft tissue mass with direct extension of vascular components into osseous tissue of the adjacent sacral vertebrae. Biopsy and subsequent histopathologic examination led to definitive diagnosis of soft tissue hemangioma. While MRI is widely regarded as the gold standard imaging modality for evaluating hemangiomas, in this report we describe how CT can aid in narrowing the differential diagnosis when one encounters a vascular lesion with adjacent osseous changes. Furthermore, we review the literature as it pertains to the imaging of soft tissue hemangiomas that occur in proximity to osseous tissue, as well as correlate this case to current theories on the pathogenesis of hemangiomas. Radiologists should be aware that benign soft tissue hemangiomas demonstrate a spectrum of imaging findings, including aggressive-appearing changes to adjacent bone.

The pulsed dye laser (PDL) using varying fluences and pulse durations have been used to treat hemangiomas. This study aims to examine the efficacy and safety of the 595-nm PDL for the treatment of infantile hemangiomas using short (1.5-3 milliseconds) versus long (10 milliseconds) pulse durations and high fluences. This is a retrospective study of patients with hemangiomas (n = 23) treated with the 595-nm PDL from 2003 to 2007. The parameters used for the short pulse duration group (n = 15) were 7-mm spot size, fluence 10-13.5 J/cm(2) and dynamic cooling device (DCD) spray duration of 50 milliseconds and delay of 30 milliseconds. For the long pulse duration group (n = 8), parameters were 7-mm spot size, fluence 10.5-14.5 J/cm(2) and DCD spray duration of 40 milliseconds and delay of 20 milliseconds. The number of treatments required to achieve complete or near complete resolution of the hemangioma ranged from 3 to 14 for the short pulse duration group (mean: 8) and for the long pulse duration group, 4-14 treatments (mean: 9). For both groups, more treatments were needed to achieve clearance of mixed hemangiomas (n = 13) compared to superficial hemangiomas (n = 10) (on average, 4-5 treatments more). Erythema, edema, and purpura lasted for about a week in the short pulse duration group but only 2 days in the long pulse duration group. There was no ulceration or hypertrophic scarring noted in both groups. Both short and long pulse durations using moderately high fluences are equally effective in the treatment of infantile hemangiomas. Shorter pulse durations had a slightly higher incidence of side effects compared to longer pulse duration in our patients with darker phototypes. Hemangiomas are tumors with relatively large diameter blood vessels and this provides the basis for the use of longer pulse durations. Copyright © 2012 Wiley Periodicals, Inc.

AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency (RF) ablation vs computed tomography (CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm. METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma. Altogether, 24 hemangiomas were ablated via a CT-guided percutaneous approach (CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach (laparoscopic ablation group). RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm (range, 6.0-12.0 cm). There was no difference in the diameter of hemangiomas between the two groups (P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups (P > 0.05). There were 23 thoracic complications in 17 patients: 15 (62.5%, 15/24) in the CT-guided ablation group and 2 (7.4%, 2/27) in the laparoscopic ablation group (P < 0.05). According to the Dindo-Clavien classification, two complications (pleural effusion and diaphragmatic rupture grade III) were major in two patients. All others were minor (grade I). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7% (22/24) and 96.3% (26/27) in the CT-guided and the laparoscopic ablation groups, respectively (P > 0.05). CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm. It avoids thermal injury to the diaphragm and reduces thoracic complications. PMID:26019459

Infantile hemangiomas (IHs) are the most common benign tumor of infancy, yet their pathogenesis is poorly understood. IHs are believed to originate from a progenitor cell, the hemangioma stem cell (HemSC). Recent studies by our group showed that NOTCH proteins and NOTCH ligands are expressed in hemangiomas, indicating Notch signaling may be active in IHs. We sought to investigate downstream activation of Notch signaling in hemangioma cells by evaluating the expression of the basic HLH family proteins, HES/HEY, in IHs. HemSCs and hemangioma endothelial cells (HemECs) are isolated from freshly resected hemangioma specimens. Quantitative RT-PCR was performed to probe for relative gene transcript levels (normalized to beta-actin). Immunofluorescence was performed to evaluate protein expression. Co-localization studies were performed with CD31 (endothelial cells) and NOTCH3 (peri-vascular, non-endothelial cells). HemSCs were treated with the gamma secretase inhibitor (GSI) Compound E, and gene transcript levels were quantified with real-time PCR. HEY1, HEYL, and HES1 are highly expressed in HemSCs, while HEY2 is highly expressed in HemECs. Protein expression evaluation by immunofluorescence confirms that HEY2 is expressed by HemECs (CD31+ cells), while HEY1, HEYL, and HES1 are more widely expressed and mostly expressed by perivascular cells of hemangiomas. Inhibition of Notch signaling by addition of GSI resulted in down-regulation of HES/HEY genes. HES/HEY genes are expressed in IHs in cell type specific patterns; HEY2 is expressed in HemECs and HEY1, HEYL, HES1 are expressed in HemSCs. This pattern suggests that HEY/HES genes act downstream of Notch receptors that function in distinct cell types of IHs. HES/HEY gene transcripts are decreased with the addition of a gamma-secretase inhibitor, Compound E, demonstrating that Notch signaling is active in infantile hemangioma cells.

Mucopolysaccharidosis I (MPS I) is a lysosomal storage disease characterized by deficient α-L-iduronidase activity, leading to the accumulation of poorly degraded glycosaminoglycans (GAGs). Children with MPS I exhibit high incidence of spine disease, including accelerated disc degeneration and vertebral dysplasia, which in turn lead to spinal cord compression and kypho-scoliosis. In this study we investigated the efficacy of neonatal enzyme replacement therapy (ERT), alone or in combination with oral simvastatin (ERT+SIM) for attenuating cervical spine disease progression in MPS I, using a canine model. Four groups were studied: normal controls; MPS I untreated; MPS I ERT treated; and MPS I ERT+SIM treated. Animals were euthanized at one year-of-age. Intervertebral disc condition and spinal cord compression were evaluated from MRIs and plain radiographs, vertebral bone condition and odontoid hypoplasia were evaluated using microcomputed tomography, and epiphyseal cartilage to bone conversion was evaluated histologically. Untreated MPS I animals exhibited more advanced disc degeneration and more severe spinal cord compression than normal animals. Both treatment groups resulted in partial preservation of disc condition and cord compression, with ERT+SIM not significantly better than ERT alone. Untreated MPS I animals had significantly lower vertebral trabecular bone volume and mineral density, while ERT treatment resulted in partial preservation of these properties. ERT+SIM treatment demonstrated similar, but not greater, efficacy. Both treatment groups partially normalized endochondral ossification in the vertebral epiphyses (as indicated by absence of persistent growth plate cartilage), and odontoid process size and morphology. These results indicate that ERT begun from a very early age attenuates the severity of cervical spine disease in MPS I, particularly for the vertebral bone and odontoid process, and that additional treatment with simvastatin does not provide a significant additional benefit over ERT alone.

The nasal cavity harbors an enormous variety of neoplasms, including epithelial and mesenchymal tumors. Hemangioma is an infrequent mesenchymal tumor of the nasal cavity, mostly arising in the mucosa and rarely in the bones. We describe the case of a 73-year-old woman who was referred to our hospital with a tumor in her left nasal cavity. The tumor originated from the left inferior turbinate. Histological examination subsequent to complete excision revealed that the tumor was an intraosseous cavernous hemangioma. To our knowledge, this is the second case of intraosseous hemangioma of the inferior turbinate reported in the English literature. PMID:20300428
Diagnosis and Management of Vertebral Compression Fractures.
McCarthy, Jason; Davis, Amy
2016-07-01
Vertebral compression fractures (VCFs) are the most common complication of osteoporosis, affecting more than 700,000 Americans annually. Fracture risk increases with age, with four in 10 white women older than 50 years experiencing a hip, spine, or vertebral fracture in their lifetime. VCFs can lead to chronic pain, disfigurement, height loss, impaired activities of daily living, increased risk of pressure sores, pneumonia, and psychological distress. Patients with an acute VCF may report abrupt onset of back pain with position changes, coughing, sneezing, or lifting. Physical examination findings are often normal, but can demonstrate kyphosis and midline spine tenderness. More than two-thirds of patients are asymptomatic and diagnosed incidentally on plain radiography. Acute VCFs may be treated with analgesics such as acetaminophen, nonsteroidal anti-inflammatory drugs, narcotics, and calcitonin. Physicians must be mindful of medication adverse effects in older patients. Other conservative therapeutic options include limited bed rest, bracing, physical therapy, nerve root blocks, and epidural injections. Percutaneous vertebral augmentation, including vertebroplasty and kyphoplasty, is controversial, but can be considered in patients with inadequate pain relief with nonsurgical care or when persistent pain substantially affects quality of life. Family physicians can help prevent vertebral fractures through management of risk factors and the treatment of osteoporosis.

The aetiology of osteoporotic vertebral fractures is multi-factorial, and cannot be explained solely by low bone mass. After sustaining an initial vertebral fracture, the risk of subsequent fracture increases greatly. Examination of physiologic loads imposed on vertebral bodies may help to explain a mechanism underlying this fracture cascade. This study tested the hypothesis that model-derived segmental vertebral loading is greater in individuals who have sustained an osteoporotic vertebral fracture compared to those with osteoporosis and no history of fracture. Flexion moments, and compression and shear loads were calculated from T2 to L5 in 12 participants with fractures (66.4 +/- 6.4 years, 162.2 +/- 5.1 cm, 69.1 +/- 11.2 kg) and 19 without fractures (62.9 +/- 7.9 years, 158.3 +/- 4.4 cm, 59.3 +/- 8.9 kg) while standing. Static analysis was used to solve gravitational loads while muscle-derived forces were calculated using a detailed trunk muscle model driven by optimization with a cost function set to minimise muscle fatigue. Least squares regression was used to derive polynomial functions to describe normalised load profiles. Regression co-efficients were compared between groups to examine differences in loading profiles. Loading at the fractured level, and at one level above and below, were also compared between groups. The fracture group had significantly greater normalised compression (p = 0.0008) and shear force (p < 0.0001) profiles and a trend for a greater flexion moment profile. At the level of fracture, a significantly greater flexion moment (p = 0.001) and shear force (p < 0.001) was observed in the fracture group. A greater flexion moment (p = 0.003) and compression force (p = 0.007) one level below the fracture, and a greater flexion moment (p = 0.002) and shear force (p = 0.002) one level above the fracture was observed in the fracture group. The differences observed in multi-level spinal loading between the groups may explain a mechanism for increased risk of subsequent vertebral fractures. Interventions aimed at restoring vertebral morphology or reduce thoracic curvature may assist in normalising spine load profiles.

To describe the surgical treatment and outcome for juvenile dogs with cranial thoracic vertebral canal stenosis treated by unilateral hemilaminectomy. Case series. Three large-breed brachycephalic dogs of various breeds (Dogue de Bordeaux, Australian Bulldog, Boerboel) with neurological signs consistent with a myelopathy of the third thoracic (T) to third lumbar (L) spinal cord segment. Information on clinical presentation, diagnostic imaging, surgical procedures, postoperative complications, recovery and outcome is described. Neurological signs were present and progressive for two to four weeks prior to surgery and ranged from mild ataxia to paralysis. Cranial thoracic vertebral canal stenosis was diagnosed with computed tomography imaging. Lateral and dorsolateral spinal cord compression was present at multiple sites between T2 and T6. Alternating left and right-sided compressions were common. Surgical treatment was by unilateral, continuous hemilaminectomy over three to six vertebral spaces. Postoperative morbidity was minimal and return of independent ambulation was rapid (median: 13.5 days, range: 2-29 days). Neurological status in one dog worsened four months after surgery due to reoccurrence of osseous compression; unilateral hemilaminectomy was repeated in this dog. Long-term follow-up ranged from six to 10 months; neurological signs had completely resolved in one dog and substantially improved in the other two dogs. Unilateral hemilaminectomy was associated with rapid return of independent ambulation and substantial improvement in neurological scores.
Severe progressive scoliosis due to huge subcutaneous cavernous hemangioma: A case report
2011-01-01
Cavernous hemangioma consists mainly of congenital vascular malformations present before birth and gradually increasing in size with skeletal growth. A small number of patients with cavernous hemangioma develop scoliosis, and surgical treatment for the scoliosis in such cases has not been reported to date. Here we report a 12-year-old male patient with severe progressive scoliosis due to a huge subcutaneous cavernous hemangioma, who underwent posterior correction and fusion surgery. Upon referral to our department, radiographs revealed a scoliosis of 85° at T6-L1 and a kyphosis of 58° at T4-T10. CT and MR images revealed a huge hemangioma extending from the subcutaneous region to the paraspinal muscles and the retroperitoneal space and invading the spinal canal. Posterior correction and fusion surgery using pedicle screws between T2 and L3 were performed. Massive hemorrhage from the hemangioma occurred during the surgery, with intraoperative blood loss reaching 2800 ml. The scoliosis was corrected to 59°, and the kyphosis to 45° after surgery. Seven hours after surgery, the patient suffered from hypovolemic shock and disseminated intravascular coagulation due to postoperative hemorrhage from the hemangioma. The patient developed sensory and conduction aphasia caused by cerebral hypoxia during the shock on the day of the surgery. At present, two years after the surgery, although the patient has completely recovered from the aphasia. This case illustrates that, in correction surgery for scoliosis due to huge subcutaneous cavernous hemangioma, intraoperative and postoperative intensive care for hemodynamics should be performed, since massive hemorrhage can occur during the postoperative period as well as the intraoperative period.

Propranolol (PRO) is the first-line drug for infantile hemangioma treatment. However, its mechanism of action remains unclear. Nuclear factor-kappa B (NF-κB) is highly expressed in tumors, directly or indirectly promoting angiogenesis. Thrombospondin-1 (TSP-1) is the most important anti-angiogenesis protein in vivo. These proteins mediate signaling pathways, probably playing an important role in hemangioma treatment. This study explored the synergistic regulation of TSP-1 and NF-κB signaling pathways in the treatment of hemangioma with PRO. The hemangioma-derived endothelial cells (HemECs) were sorted out from the specimens of proliferative hemangioma by flow cytometry. Furthermore, a BALB/c nude mice hemangioma model was established. Viability and proliferation of HemECs, and the role of TSP-1 and NF-κB signaling pathways were observed after PRO administration in vitro and in vivo. The expressions of TSP-1 and its receptor cluster of differentiation 36 (CD36) in HemECs gradually increased with the increase in PRO concentration, while the expressions of NF-κBp65, phosphorylated inhibitor of kappa B alpha (p-IκBα), and phosphorylated inhibitor of NF-κB kinase beta (p-IκKβ) weakened gradually (p < 0.05). In vivo, the tumors shrank gradually after PRO treatment, with increase in TSP-1 and CD36, and decrease in NF-κBp65, p-IκBα, and p-IκKβ (p < 0.05). Glucocorticoid improved the anti-angiogenesis mediated by TSP-1/CD36 and inhibited the angiogenesis mediated by NF-κB/IκB (p < 0.05). Negative regulation occurred between the two signaling pathways. The treatment of infantile hemangioma with PRO is promising to promote TSP-1-mediated anti-angiogenesis and block NF-κB-mediated angiogenesis.

Hemangioma is the most common tumor of infancy. Although it has a basically benign nature and usually spontaneously regresses, a small percentage (5%) have complications that need treatment. Many different therapeutic modalities can be used in this tumor. To investigate the effect of a new method of treatment (intralesional bleomycin injection) in complicated hemangiomas. In the Department of Radiation Oncology at Nemazee Hospital in Shiraz, Iran, from April 1992 to October 1998, 32 patients with complicated hemangioma were treated with four to six courses of direct injection of bleomycin into the lesion. After a minimum follow-up of 6 years, there was 70 to 100% regression in 18 patients, 50 to 70% in 7 cases, and less than 50% reduction in 7 patients. Intralesional injection of bleomycin is an easy, safe, and effective therapeutic modality in complicated cutaneous hemangiomas.

The cavernous hemangioma is a rare benign vascular tumor. About 50 cases of this disease were found in the literature over the last century and only 9 cases of cavernous hemangioma on the pregnant uterus were published it comes into cavernous or capillary form. The symptomatology is not unequivocal and when it occurs during pregnancy or postpartum, it causes life-threatening cataclysmic hemorrhage. Antenatal diagnosis is difficult and requires a multidisciplinary approach with pathologists, radiologists and gynecologists to avoid these complications or unnecessary hysterectomies. The diagnosis is histological. Hysterectomy is possible after failure of conservative treatment means. We report a rare case, a novel mixed cavernous hemangioma of the body associated with a capillary hemangioma of the cervix in a patient of 28 years 5th visors with recurrent genital bleeding in the postpartum period leading to a hysterectomy.

Percutaneous vertebroplasty is a widely used vertebral augmentation procedure for treating osteoporotic vertebral compression fractures (OVCFs). But high cement leakage rate caused by a low-viscosity cement and high injection pressure has limited its general use. Balloon kyphoplasty (BKP) and high-viscosity cement vertebroplasty (HVCV) are 2 modifications of vertebroplasty designed to decrease cement leakage. To assess the safety and efficacy of HVCV compared with BKP. A prospective cohort study. Department of Spine Surgery, an affiliated hospital of a medical university. One hundred seven patients suffering from painful OVCFs were randomly assigned into HVCV or BKP groups. Visual Analog Scale (VAS), Oswestry Disability Index (ODI), cement leakage, and vertebral height restoration were evaluated. All occurring complications and injected cement volumes were recorded. The follow-up time was one year. VAS and ODI scores improved in both groups, and did not differ significantly between the 2 groups. More cement was used in the BKP group than in HVCV group (4.22 vs. 3.31 mL, P < 0.0001). The incidence of cement leakage in the HVCV group was lower than that of the BKP group (13.24% vs 30.56%, P < 0.05). No symptomatic cement leakages occurred in the HVCV group. In the BKP group, one patient experienced discogenic back pain related to a disc leak, and another patient had asymptomatic cement emboli in the lung related to venous leakage. The mean compression rate before the procedure was 29.98% in the HVCV group and 28.67% in the BKP group (P = 0.94). The vertebral height was improved significantly and maintained at one-year follow-up in both groups. BKP was more effective in vertebral height restoration than HVCV (44.87% vs. 23.93%, P < 0.0001). There was one case of a new adjacent vertebral fracture in the HVCV group (2%), and 4 cases of new nonadjacent vertebral fractures in the BKP group (7.84%) (P = 0.18). A single-center and relatively small-sample size study. HVCV and BKP are safe and effective in improving quality of life and relieving pain. HVCV has a lower cement leakage rate, whereas BKP is more effective in vertebral height restoration. Subsequent fractures are not different between the 2 groups.

Intrahepatic portosystemic venous shunts (IPVS) are rare, except for the minute ones observed in cirrhotic liver. This report concerns a case with frequent episodes of consciousness loss, diagnosed as IPVS and multiple hemangioma-like lesions of the liver by US, CT and angiography. To our knowledge, this is the first report of association of IPVS and such angiographically evident hemangioma-like lesions of the liver. The etiology of IPVS is mostly considered to be congenital though, there are still many arguments about it. The relation between IPVS and the hemangioma-like lesions of the liver is discussed.

Purpose: Cavernous sinus hemangioma is a rare vascular tumor. The direct microsurgical approach usually results in massive hemorrhage. Although radiosurgery plays an important role in managing cavernous sinus hemangiomas as a treatment alternative to microsurgery, the potential for increased toxicity with single-session treatment of large tumors is a concern. The purpose of this study was to assess the efficacy of hypofractionated stereotactic radiotherapy in patients with large cavernous sinus hemangiomas. Methods: Fourteen patients with large (volume >20 cm{sup 3}) cavernous sinus hemangiomas were enrolled in a prospective Phase II study between December 2007 and December 2010. The hypofractionated stereotactic radiotherapymore » dose was 21 Gy delivered in 3 fractions. Results: After a mean follow-up of 15 months (range, 6-36 months), the magnetic resonance images showed a mean of 77% tumor volume reduction (range, 44-99%). Among the 6 patients with cranial nerve impairments before hypofractionated stereotactic radiotherapy, 1 achieved symptomatic complete resolution and 5 had improvement. No radiotherapy-related complications were observed during follow-up. Conclusion: Our current experience, though preliminary, substantiates the role of hypofractionated stereotactic radiotherapy for large cavernous sinus hemangiomas. Although a longer and more extensive follow-up is needed, hypofractionated stereotactic radiotherapy of 21 Gy delivered in 3 fractions is effective in reducing the tumor volume without causing any new deficits and can be considered as a treatment modality for large cavernous sinus hemangiomas.« less

Cervical spondylomyelopathy or Wobbler syndrome commonly affects the cervical vertebral column of Great Dane dogs. Degenerative changes affecting the articular process joints are a frequent finding in these patients; however, the correlation between these changes and other features of cervical spondylomyelopathy are uncertain. We described and graded the degenerative changes evident in the cervical articular process joints from 13 Great Danes dogs with cervical spondylomyelopathy using MR imaging, and evaluated the relationship between individual features of cervical articular process joint degeneration and the presence of spinal cord compression, vertebral foraminal stenosis, intramedullary spinal cord changes, and intervertebral disc degenerative changes. Degenerative changes affecting the articular process joints were common, with only 13 of 94 (14%) having no degenerative changes. The most severe changes were evident between C4-C5 and C7-T1 intervertebral spaces. Reduction or loss of the hyperintense synovial fluid signal on T2-weighted MR images was the most frequent feature associated with articular process joint degenerative changes. Degenerative changes of the articular process joints affecting the synovial fluid or articular surface, or causing lateral hypertrophic tissue, were positively correlated with lateral spinal cord compression and vertebral foraminal stenosis. Dorsal hypertrophic tissue was positively correlated with dorsal spinal cord compression. Disc-associated spinal cord compression was recognized less frequently. © 2011 Veterinary Radiology & Ultrasound.

Percutaneous vertebroplasty (PVP) typically involves conventional lower-viscosity cement injection via bipedicular approach. Limited evidence is available comparing the clinical outcomes and complications in treating osteoporotic vertebral compression fractures (OVCFs) with PVP using high-viscosity cement through unipedicular or bipedicular approach. Fifty patients with OVCFs were randomly allocated into two groups adopting unipedicular or bipedicular PVP. The efficacy of unipedicular and bipedicular PVP was assessed by comparing operation time, X-ray exposure time, incidence of complications, vertebral height restoration, and improvement of the visual analogue scale (VAS), Oswestry disability index (ODI) and Short Form-36 (SF-36) General Health Survey scores. The mean operative and exposure time to X-rays in the unipedicular PVP group was less than that of the bipedicular group (p < 0.05). No statistically significant differences were observed in the VAS score, ODI score, SF-36 score, cement leakage rate or vertebral height restoration between the two groups (p > 0.05). Unipedicular and bipedicular PVP are safe and effective treatments for OVCF. Compared with bipedicular PVP, unipedicular PVP entails a shorter surgical time and lower X-ray irradiation.

A 47-year-old woman with a history of anaemia presented to the emergency room with an acute onset of leg weakness. Physical examination of the bilateral lower extremities was significant for 0/5 muscle strength in all muscle groups with decreased pinprick and temperature sensation. A sensory level at the umbilicus was appreciated. Fine touch and proprioception were preserved. Bowel and bladder function were intact. CT revealed several thoracic, vertebral haemangiomatas. An MRI was suggestive of an epidural clot at the T8-T10-weighted posterior epidural space. At the level of the lesion, the cerebrospinal fluid space was completely effaced, and the flattened spinal cord exhibited signs of oedema and compressive myelopathy. The patient immediately underwent surgical decompression of the spinal cord. An epidural clot and vessel conglomeration were identified. A postoperative spinal angiogram confirmed the diagnosis of vertebral haemangioma. At 1-month follow-up, the patient regained strength and sensation.

Microvascular endothelial cells cultured in three-dimensional hydrogel scaffolds form a network of microvessel structures when implanted subcutaneously in mice, inosculate with host vessels and over time remodel into large ectatic vascular structures resembling hemangiomas. When compared to infantile hemaniomas similarities were noted including a temporal progression from a morphological appearance of a proliferative phase to the appearance of an involuted phase mimicking the proliferative and involutional phases of infantile hemangioma. Consistent with the progression of a proliferative phase to an involuted phase, both the murine implants and human biopsy tissue exhibit reduced expression of Ajuba, YAP and Survivin labeling as they progressed over time. Significant numbers of CD45+, CD11b+, Mac3+ mononuclear cells were found at the 2 week time point in our implant model which correlated with the presence of CD45+, CD68+ mononuclear cells observed in biopsies of human proliferative phase hemangiomas. At the 4 week time point in our implant model only small numbers of CD45+ cells were detected, which again correlated with our findings of significantly diminished CD45+, CD68+ mononuclear cells in human involutional phase hemangiomas. The demonstration of mononuclear cell infiltration transiently in the proliferative phase of these lesions suggests that the vascular proliferation and/or regression may be driven in part by an immune response. Gross and microscopic morphological appearances of human proliferative and involutional hemangiomas and our implant model correlate well with each other as do the expression levels of Hippo pathway components (Ajuba and YAP) and Survivin and correlate with proliferation in these entities. Inhibitors of Survivin and Ajuba (which we have demonstrated to inhibit proliferation and increase apoptosis in murine hemangioma cell tissue culture) may have potential as other beneficial treatments for proliferating infantile hemangiomas. This implant model may have potential as a modest through-put screen for testing and development of therapeutics targeted at the proliferative phase of infantile hemangiomas, reducing the subsequent post-involutional scarring sometimes associated with these lesions.

The informational gains obtained by the use of pinhole collimator scintigraphy (PCS) have been well documented. The present study has been undertaken to prospectively investigate its efficacy in diagnosing several commonly occurring spinal diseases. Patient material consisted of metastatic cancer (39 vertebrae), compression fractures (33 vertebrae), tuberculous spondylitis (17 vertebrae), and pyogenic spondylitis (six vertebrae). PCS findings were characterized in terms of localization, appearance, and homogeneity of abnormal radionuclide accumulation. Thus, metastatic cancer manifested as diffusely or focally homogeneous accumulation within the vertebral body or as a typical short-segmental accumulation along the end-plate, whereas compression fracture manifested as characteristic board-likemore » accumulation along the entire length of end-plates. Tuberculous spondylitis, on the other hand, revealed homogeneous accumulation throughout the vertebral body, and pyogenic spondylitis revealed accumulation at the end-zone of opposing vertebral bodies giving sandwich-like appearance. The disk space at the affected level was not narrowed in the former two diseases but it was narrowed in the latter two. It was concluded that PCS may be useful in differentiating metastatic cancer, compression fracture, tuberculous spondylitis, and pyogenic spondylitis.« less
Primary surgical excision for pediatric orbital capillary hemangioma.
Krema, Hatem
2015-05-01
We report the technique and outcome of surgical excision of subcutaneous orbital capillary hemangioma causing eye globe displacement in two children. Primary surgical excision was performed with blunt dissection along the tumor walls using a cotton-tipped applicator as the dissecting tool with simultaneous outward gentle traction on the tumor wall. Despite the deep and extensive orbital involvement, complete excision of the hemangiomas was achievable with this technique, which permitted excellent visualization of the surgical planes throughout the procedures. Deep and extensive pediatric orbital capillary hemangioma can be surgically excised with the suggested technique, which obviates the need for intralesional or systemic medical therapy, yielding optimal cosmetic and functional outcomes, shortly after surgery.

Argon laser therapy is effective for removing port-wine stains and for reducing cutaneous vascular and pigmented lesions. Strawberry hemangiomas, being much thicker lesions than port-wine stains, were considered not appropriate for argon laser treatment. Using argon laser therapy in 13 cases of strawberry hemangioma, we achieved poor to dramatic results. ImagesFigure 1.Figure 2.Figure 3.Figure 4.Figure 5.Figure 6.Figure 7. PMID:4082569

Intraosseous hemangiomas are benign vascular malformations mostly seen in the spine. They rarely occur in the skull. The usual age-group involved is the 2nd to 4th decades, and females outnumber males. We hereby report a rare case of congenital intraosseous cavernous hemangioma of the skull bone in a male infant. The patient underwent total excision of the lesion. © 2014 S. Karger AG, Basel.

Intraosseous hemangiomas are benign vascular tumors that are encountered most commonly in vertebrae and rarely in the skull. When presenting in the skull, they are commonly found in the calvarium in frontal and parietal bones and seldom in the skull base. We encountered a patient with an incidental finding on magnetic resonance imaging (MRI) of an enhancing lesion in the clivus. Here we report an unusual location of a clival intraosseous hemangioma. A 62 year old man worked up for carpal tunnel syndrome had imaging of his cervical spine that revealed an enhancing clival lesion, which extended into the left occipital condyle. Endoscopic endonasal biopsy was performed on the abnormality revealing a capillary hemangioma. Patient tolerated the biopsy well and no further surgical intervention is indicated at this time. Patient will be followed at six month intervals. Primary intraosseus hemangiomas of the skull are extremely rare and usually occur in the calvarium. This is one of the few reported case of an intraosseus hemangioma in the clivus. We present this case in part because it is unusual, but more importantly, with the wider use of MRI, it is likely that these lesions will be discovered more frequently, and conceivably confused for more dangerous lesions.

To evaluate three methods for treating adult laryngeal hemangiomas: conventional chemotherapy, CO 2 laser combined with chemotherapy, and KTP laser. And to identify risk factors that affected the prognosis of the lesions. A retrospective analysis was performed on the data from patients with adult laryngeal hemangiomas treated by one of three aforementioned methods, the curative efficacy, and safety of those methods was compared. All cases were confirmed by suspension micro-laryngoscope examination. Pre- and post-treatment clinical photographs were taken and the outcomes were graded. Thirty-eight patients in 48 different cases were enrolled in the study between June 2010 and June 2016, and some patients were treated more than once. The treatment efficacy of the KTP laser was higher than that of chemotherapy according to the Kruskal-Wallis ANOVA test; however, the ordinal logistic regression showed that the choice of surgical procedure did not affect the treatment results; only the size of the bases of the lesions affected the prognosis of adult laryngeal hemangiomas. Pingyangmycin injection, KTP laser, and CO 2 laser combined with chemotherapy are safe and effective methods for the treatment of adult laryngeal hemangiomas. The size of base of the lesion affects the prognosis of the hemangiomas.

PELVIS is an acronym defining the association of perineal hemangioma, malformations of external genitalia, lipomyelomeningocele, vesicorenal abnormalities, imperforate anus and skin tag. Eleven cases have been reported according to the Orphanet data. Acronyms of LUMBAR and SACRAL syndrome have been used and most probably represent a spectrum of the same entity. Very little is known about the success and timing of cloacal reconstruction after the treatment of hemangioma. We present a variant of PELVIS syndrome and discuss the possibilities and optimal timing of surgical reconstruction. Female infant was born with persistent cloaca and multiple hemangiomas of genitals, perineal area and left thigh. Colostomy was performed after birth. In order to treat hemangioma and to make the reconstruction of cloaca possible, corticosteroid treatment orally and multiple laser treatments were performed alternating Nd:YAG laser and pulsed dye laser therapy. Cystoscopy confirmed hemangiomatosis in the mucosa of the common channel, bladder neck and septate vagina. Oral propranolol treatment was started at the age of 18 months and continued for 1 year. It induced rapid improvement of hemangiomas. Two more pulsed dye laser treatments were performed to remove residuals of hemangiomas from the perineum and genital area. Posterior sagital reconstruction by separation of the rectum, mobilization of urogenital sinus and vaginal reconstruction was performed with no major bleeding at the age of 4 years. Postoperatively, after a period of progressive rectal dilatation colostomy was closed. Girl is now 6 years old, dry day and night without residual urine and normal upper tracts. Rectal calibration is normal, fecal continence is still to be evaluated but constipation is easily manageable. CT of the spine and the perineum showed sacral dysplasia and spina bifida with lumbo-sacral lipoma and tethering of terminal filum without neurological deterioration at the moment but requiring close neurological monitoring. Large perineal hemangiomas are commonly associated with extracutaneous abnormalities. Successful reconstructive surgery is possible after significant reduction of hemangioma by complex treatment.

Minimally invasive cement augmentation of painful osteoporotic vertebral compression fractures in elderly patients. Painful osteoporotic vertebral compression fractures in elderly patients (> 65 years of age) after conservative therapy failure. Painful aggressive primary tumors of the spine or osteolytic metastases to the spine with high risk of vertebral fracture in the palliative care setting. General contraindications for surgical interventions. Local soft-tissue infection. Osteomyelitis, discitis or systemic infection. Coagulopathy refractory to treatment or bleeding diathesis. Asymptomatic vertebral compression fractures. Burst of the posterior vertebral column with high degree of spinal canal stenosis. Primary or metastatic spinal tumors with epidural growth. Prone position on a radiolucent operating table. Fluoroscopic localization of the fractured vertebra using two conventional C-arm devices (anteroposterior and lateral views). Fluoroscopic localization of the fractured vertebra using two conventional C-arm devices (anteroposterior and lateral views). An introducer is inserted through a small skin incision into the pedicle under fluoroscopic guidance. To create a site- and size-specific three-dimensional cavity in the center of the fractured vertebra, the navigational VertecoR™ MidLine Osteotome was inserted through the correctly sited introducer and guided fluoroscopically. As the MidLine Osteotome allows angulation of the tip up to 90° by rotating the handle, a cavity over the midline of the vertebral body can mainly be created through one pedicle. The radiofrequency activated cohesive ultrahigh viscosity PMMA cement (ER(2) bone cement) is injected stepwise on demand by remote control under continuous pressure from the hydraulic assembly into the vertebral body. Bed rest for 6 h postoperatively in supine position. Early mobilization without a corset on the day of surgery. Specific back and abdominal exercises that strengthen the back and abdominal muscles. Pain dependent increase of weight bearing. Continue osteoporosis therapy and start specific drug therapy according to the local guidlines if necessary. In all, 44 patients (29 women, 15 men) with a mean age of 73.5 years with a total of 62 painful osteoporotic vertebral fractures were treated with RF kyphoplasty from May 2009 until July 2010, and followed over a period of 12 months. The mean operating time per patient was 36.2 min, the operating time per vertebra was 25.7 min. All the patients studied experienced an early and persistent significant pain relief even 12 months after therapy (8 ± 1.4 vs. 2.7 ± 1.9) according to the visual analogue pain scale. According to the Oswestry Disability Index (ODI) as a disease-specific disability measure all the patients improved significantly (p < 0.001) in the level of disability after operative treatment (56.2 ± 18.8 vs. 34.5 ± 16.6). Cement leakage was detected in 17 out of 62 (27.4 %) augmented vertebrae, whereas all the patients with cement leakage remained asymptomatic. One patient had subsequent vertebral fractures after a period of 6 months.

Percutaneous cement augmentation systems have been proven to be an effective treatment for vertebral compression fractures in the last 10 years. A special form available since 2009 is the radiofrequency kyphoplasty (RF) in which the applied energy raises the viscosity of the cement. The aim of this study is to find out if a smaller cement amount in radiofrequency kyphoplasty can also restore vertebral body height in osteoporotic vertebral compression fractures. The treatment was minimally invasive using the StabiliT® vertebral augmentation system by DFine. In a retrospective study from 2011 to January 2012, 35 patients underwent RF kyphoplasty for 49 fresh osteoporotic vertebral compression fractures. From the clinical side the parameters, demographics and pain relief using a visual analogue scale (VAS: 0 to 100 mm) were collected. For the radiological outcome the vertebral body height (anterior, mean and posterior vertebral body height with kyphosis angle) after surgery and after three months was measured and compared to the cement volume. All patients still had permanent pain on the fractured level after conservative treatment. The time from initial painful fracture to treatment was 3.0 weeks ± 1.3. Average visual analogue scale results decreased significantly from 71 ± 9.2 preoperatively to 35 ± 6.2 postoperatively (p < 0.001) and to 30 ± 5.7 (p < 0.001) after three months. With a mean cement volume in the thoracic spine of 2.9 ± 0.7 ml (1.8-4.1) and lumbar spine of 3.0 ± 0.7 ml (2.0-5.0) we had a significant vertebral body height restoration. Anterior and mean vertebral body heights significantly increased by an average of 2.3 and 3.1 mm, kyphosis angle significantly decreased with an average of 2.1° at three-month follow-up (p < 0.05). In two vertebrae (4.1 %) a minimal asymptomatic cement leakage occurred into the upper disc. In two patients (5.7 %) we had new fractures in the directly adjacent segment that were also successfully treated with radiofrequency kyphoplasty. With a mean cement volume of 3.0 ml radiofrequency kyphoplasty achieves rapid and short-term improvements of clinical symptoms with a significant restoration of vertebral body height. There was no correlation between restoration of vertebral body height and pain relief. With a cement leakage of 4.1 % RF kyphoplasty is a safe and effective minimally invasive percutaneous cement augmentation procedure. Our data confirm the higher safety described in literature for kyphoplasty in contrast to vertebroplasty. Georg Thieme Verlag KG Stuttgart · New York.

Loading during concurrent bending and compression associated with deadlift, hang clean and hang snatch lifts carries the potential for injury to the intervertebral discs, muscles and ligaments. This study examined the capacity of a newly developed spinal model to compute shear and compressive forces, and bending moments in lumbar spine for each lift. Five male subjects participated in the study. The spine was modeled as a chain of rigid bodies (vertebrae) connected via the intervertebral discs. Each vertebral reference frame was centered in the center of mass of the vertebral body, and its principal directions were axial, anterior-posterior, and medial-lateral. The results demonstrated the capacity of this spinal model to assess forces and bending moments at and about the lumbar vertebrae by showing the variations among these variables with different lifting techniques. These results show the model's potential as a diagnostic tool.

This study investigated the effect of endplate deformity after an osteoporotic vertebral fracture in increasing the risk for adjacent vertebral fractures. Eight human lower thoracic or thoracolumbar specimens, each consisting of five vertebrae were used. To selectively fracture one of the endplates of the middle VB of each specimen a void was created under the target endplate and the specimen was flexed and compressed until failure. The fractured vertebra was subjected to spinal extension under 150 N preload that restored the anterior wall height and vertebral kyphosis, while the fractured endplate remained significantly depressed. The VB was filled with cement to stabilize the fracture, after complete evacuation of its trabecular content to ensure similar cement distribution under both the endplates. Specimens were tested in flexion-extension under 400 N preload while pressure in the discs and strain at the anterior wall of the adjacent vertebrae were recorded. Disc pressure in the intact specimens increased during flexion by 26 ± 14%. After cementation, disc pressure increased during flexion by 15 ± 11% in the discs with un-fractured endplates, while decreased by 19 ± 26.7% in the discs with the fractured endplates. During flexion, the compressive strain at the anterior wall of the vertebra next to the fractured endplate increased by 94 ± 23% compared to intact status (p < 0.05), while it did not significantly change at the vertebra next to the un-fractured endplate (18.2 ± 7.1%, p > 0.05). Subsequent flexion with compression to failure resulted in adjacent fracture close to the fractured endplate in six specimens and in a non-adjacent fracture in one specimen, while one specimen had no adjacent fractures. Depression of the fractured endplate alters the pressure profile of the damaged disc resulting in increased compressive loading of the anterior wall of adjacent vertebra that predisposes it to wedge fracture. This data suggests that correction of endplate deformity may play a role in reducing the risk of adjacent fractures. PMID:18795344

Hemangiomas of the bone are benign, uncommon, slow-growing lesions accounting for <1.0% of all bony neoplasms. Intraosseous occipital hemangiomas are rare, and occipital hemangiomas presenting with features of raised intracranial tension are, with only 2 cases reported to date. In this case report, we describe the unique case of a 30-year-old male patient presenting with raised intracranial pressure due to venous obstruction at the torcula. The patient underwent excision of the lesion and became symptom free. Although these are benign lesions, they can have a varied clinical presentation. An understanding of the different clinical presentations and surgical nuances in excising such tumors can lead to early diagnosis and good patient outcome. Copyright © 2017 Elsevier Inc.

A photon-deficient ('cold') vertebra on fluorine-18 fluorodeoxyglucose (F-FDG) PET is a known entity and can arise as a result of varying etiologies. A proper interpretation of this observation is required to make an accurate diagnosis for appropriate management. Twelve cases with 'cold' vertebrae on F-FDG PET/computed tomography (CT) were selected and analyzed from a population of 600 patients with a known malignancy who had undergone whole-body F-FDG PET/CT for staging, disease viability assessment, response to treatment, or suspected recurrence purposes. The patterns were studied and correlated with clinical history and the results of the low-dose CT performed with the PET scan for attenuation correction and anatomical localization. The most common cause for cold vertebrae was found to be postexternal radiotherapy, causing photopenia involving multiple vertebrae corresponding to the radiotherapy portals. Two other causes found in the study were the destruction of the vertebral marrow cavity by metastatic tumor cells and vertebral hemangioma. Characteristic features of 'cold' vertebrae have been described in the study with illustrations. Pattern recognition coupled with clinical history and CT correlation of 'cold' vertebrae on F-FDG PET/CT can help in diagnosing the correct underlying etiology, which can help in better management of the patients.

Cushing disease in children and adolescents, especially with multiple pituitary adenomas (MPAs), is very rare. We report 17-year-old boy with MPAs. He presented with a vertebral compression fracture, weight gain, short stature, headache, and hypertension. On magnetic resonance imaging (MRI), only a left pituitary microadenoma was found. After surgery, transient clinical improvement was observed but headache and hypertension were observed again after 3 months later. Follow-up MRI showed a newly developed right pituitary microadenoma 6 months after the surgery. The need for careful clinical and radiographic follow-up should be emphasized in the search for potential MPAs in patients with persistent Cushing disease.

Purpose: To investigate the potential utility of in-line phase-contrast imaging (ILPCI) technique with synchrotron radiation in detecting early hepatocellular carcinoma and cavernous hemangioma of live using in vitro model system. Methods: Without contrast agents, three typical early hepatocellular carcinoma specimens and three typical cavernous hemangioma of live specimens were imaged using ILPCI. To quantitatively discriminate early hepatocellular carcinoma tissues and cavernous hemangioma tissues, the projection images texture feature based on gray level co-occurrence matrix (GLCM) were extracted. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, difference average, difference entropy and inverse difference moment, were obtained respectively.more » Results: In the ILPCI planar images of early hepatocellular carcinoma specimens, vessel trees were clearly visualized on the micrometer scale. Obvious distortion deformation was presented, and the vessel mostly appeared as a ‘dry stick’. Liver textures appeared not regularly. In the ILPCI planar images of cavernous hemangioma of live specimens, typical vessels had not been found compared with the early hepatocellular carcinoma planar images. The planar images of cavernous hemangioma of live specimens clearly displayed the dilated hepatic sinusoids with the diameter of less than 100 microns, but all of them were overlapped with each other. The texture parameters of energy, inertia, entropy, correlation, sum average, sum entropy, and difference average, showed a statistically significant between the two types specimens image (P<0.01), except the texture parameters of difference entropy and inverse difference moment(P>0.01). Conclusion: The results indicate that there are obvious changes in morphological levels including vessel structures and liver textures. The study proves that this imaging technique has a potential value in evaluating early hepatocellular carcinoma and cavernous hemangioma of live.« less

It is characterized by the association of posterior fossa malformations, hemangiomas, arterial anomalies, coarctation of the aorta and other cardiac defects, and eye abnormalities. Since most articles focus on isolated case reports, an extended retrospective literature review of all reports of large hemangiomas with associated abnormalities of the central nervous system and other malformations was performed to examine the clinical features, and other not as yet reported associated anomalies. Reports were found on 59 patients with PHACE syndrome, to which we added ten cases of our own. The Dandy-Walker syndrome is the most common CNS abnormality reported in association with PHACE syndrome and was seen in 48 (81 %) patients. Arterial malformations were found in 13 (22 %) cases; only 11 patients (19 %) had structural arterial abnormalities without associated Dandy-Walker complex. As published, about one third of patients (31 %) had further ophthalmologic abnormalities, and cardiac anomalies, including coarctation of the aorta. Subglottic hemangiomas were seen in 4 (7 %) patients and ventral developmental defects also in 3 cases. In seven of 59 patients (12 %) with PHACE syndrome, intracranial hemangiomas were present. This study demonstrates that among other CNS abnormalities, special attention should be given to intracranial hemangiomas which seems to be a peculiar phenotype of PHACE syndrome. We therefore suggest that a sixth criterion should be added to the five minimal inclusion criteria for PHACE syndrome. The inclusion criteria would then be: arterial abnormalities or/and intracranial hemangiomas. On the basis of our experience with our patients and with those previously reported, we stress the importance of using contrast-enhanced imaging to detect intracranial lesions.

Prevalent vertebral compression fracture(s) have been reported as having a negative impact on pain, disability, and quality of life. But no study has evaluated the effect of previous fracture on the course of acute compression fractures. The aim of the present study was to compare the natural course of the acute compression fracture in patients with (n = 51) and without (n = 56) previous vertebral compression fracture(s). The study is a retrospective analysis of a prospective cohort followed with postal questionnaires during a 12-month period after an acute fracture event. Eligible patients were those over 40 years of age, who were admitted to the emergency unit because of back pain and had an X-ray confirmed acute vertebral body fracture. A total of 107 patients were included in the study. The pain, disability (von Korff pain and disability scores), ADL (Hannover ADL score), and quality of life (QoL) (EQ-5D) were measured after 3 weeks, and 3, 6, and 12 months. The X-rays from the first visit to the emergency unit were evaluated. The difference of the scores between the groups with and without previous fracture was statistically significant (P < 0.05) at 3 weeks, 6 and 12 months for von Korff disability score, at all occasions for EQ-5D and at 3-12 months for Hannover ADL score, but only at 12 months for the von Korff pain intensity score. In both the groups all scores had improved in a statistically significant way at 3 months. The number of previous fractures was related to all the outcome scores in a statistically significant way (P < 0.05) except von Korff pain intensity score at 3 weeks and 3 months and von Korff disability score at 3 months. In conclusion, disability, ADL, and QoL scores, but not pain intensity score, were significantly worse in the patients with previous fracture from the fracture episode through the first 12 months. However, the improvements during the follow-up year seen in both groups were of a similar magnitude. The presence or absence of a previous fracture in an acutely fractured patient will influence the prognosis and thus possibly also the indications for treatments.

Topical application of timolol cream is effective and convenient for treating superficial infantile hemangiomas. Intralesional injection of corticosteroids, such as diprospan, is useful for the treatment of superficia infantile hemangiomas without systemic side effects. We conducted a self-controlled study to investigate whether a combination of intralesional injection of diprospan with topical timolol 0.5% cream would be more efficient than timolol cream alone in thick superficial infantile hemangiomas. Thirty-eight patients with 39 thick superficial infantile hemangiomas were recruited. Each lesion was randomly divided into two equal parts: one part was treated with topical timolol 0.5% cream (timolol cream group), while the other part was treated with injection of diprospan combined with topical timolol 0.5% cream (combined treatment group). Infants were followed every 4 weeks to determine whether injections should be continued, and timolol cream was applied four times daily for 5 months. During 5 months of treatment, three specialist physicians were invited to evaluate the therapeutic effects. The combined treatment group showed better lesion involution than did the timolol cream group regarding lesion thickness and color of lesions. The combination of intralesional injection of diprospan with topical timolol 0.5% cream is a suitable and safe strategy for thick superficial infantile hemangiomas. © 2018 Wiley Periodicals, Inc.

Vertebral compression fractures can result from advanced osteoporosis, or less commonly from metastatic or traumatic insults to the vertebral column, and result in disabling pain and decreased functional capacity. Various vertebral augmentation options including kyphoplasty aim at preventing the sequelae of pain and immobility that can develop as the result of the vertebral fractures. The mechanism for pain relief following kyphoplasty is not entirely understood, and the restoration of a portion of the lost vertebral height is a subject of debate. We retrospectively reviewed radiographic imaging, pain relief, analgesic intake and functional outcomes in 67 consecutive patients who underwent single- or multilevel kyphoplasty with the primary goal of quantifying the restoration of lost vertebral height. We observed a mean of 45% of the lost vertebral height restored postprocedurally. Secondarily, kyphoplasty was associated with significant decreases in pain scores, daily morphine consumption and improvement in patient-reported functional measures. © 2013 World Institute of Pain.

This study aimed to describe 99mTc-labeled RBC scintigraphy as a diagnostic method for orbital cavernous hemangiomas and to evaluate this diagnostic tool according to surgical outcomes. Fifty-five patients with clinical and radiological (US, CT, and/or MRI) suspicion of unilateral cavernous hemangioma of the orbit underwent 99mTc-RBC SPECT study.Qualitative and semiquantitative evaluations were performed, and results were statistically analyzed. SPECT images showed focal uptake in the orbital mass in 36 of 55 patients. Nineteen patients had a negative scintigraphic pattern, with concordance of early and late absence of uptake of 99mTc-RBC.Our procedure showed 100% sensitivity and 88.9% specificity for the diagnosis of orbital cavernous hemangioma, with a positive predictive value of 90.9% and a negative predictive value of 100%. 99mTc-RBC imaging is safe, easy to perform, and highly accurate in providing adequate clinical and surgical management. As a noninvasive and highly specific method for diagnosing orbital hemangioma, 99mTc-RBC scintigraphy can avoid more invasive imaging or biopsy.

We present a young asymptomatic woman with splenomegaly and a large isolated splenic mass demonstrated by ultrasonography, /sup 99m/Tc sulfur colloid, and gallium scintigraphy studies. Computerized tomography (CT) and three-phase 99mTc-labeled red blood cell imaging suggested a malignant lesion. Repeated sonographically guided fine needle aspiration (FNA) obtained only blood, suggesting the possible vascular nature of the tumor. Splenectomy established the diagnosis of splenic hemangioma (SH) with marked sclerotic changes. We conclude from this case that (1) the sclerotic and cystic changes in the SH and the abdominal lymphadenopathy could explain why the three-phase red blood cell and CT scanning, respectively,more » suggested that the lesion was malignant rather than benign; (2) guided FNA of a splenic mass suspected to be hemangioma may be an additional safe and useful diagnostic procedure. Multiple aspirations yielding blood alone suggest hemangioma and may prevent an unnecessary operation. To the best of our knowledge, this is the first reported case in the literature of FNA of splenic hemangioma.« less
Urea immunoliposome inhibits human vascular endothelial cell proliferation for hemangioma treatment
2013-01-01
Background Urea injection has been used in hemangioma treatment as sclerotherapy. It shrinks vascular endothelial cells and induces degeneration, necrosis, and fibrosis. However, this treatment still has disadvantages, such as lacking targeting and difficulty in controlling the urea dosage. Thus, we designed a urea immunoliposome to improve the efficiency of treatment. Methods The urea liposome was prepared by reverse phase evaporation. Furthermore, the urea immunoliposome was generated by coupling the urea liposome with a vascular endothelial growth factor receptor (VEGFR) monoclonal antibody using the glutaraldehyde cross-linking method. The influence of the urea immunoliposome on cultured human hemangioma vascular endothelial cells was observed preliminarily. Results Urea immunoliposomes showed typical liposome morphology under a transmission electron microscope, with an encapsulation percentage of 54.4% and a coupling rate of 36.84% for anti-VEGFR. Treatment with the urea immunoliposome significantly inhibited the proliferation of hemangioma vascular endothelial cells (HVECs) in a time- and dose-dependent manner. Conclusions The urea immunoliposome that we developed distinctly and persistently inhibited the proliferation of HVECs and is expected to be used in clinical hemangioma treatment. PMID:24266957

Stress magnitude and variability as estimated from large scale finite element (FE) analyses have been associated with compressive strength of human vertebral cancellous cores but these relationships have not been explored for whole vertebral bodies. In this study, the objectives were to investigate the relationship of FE-calculated stress distribution parameters with experimentally determined strength, stiffness, and displacement based ductility measures in human whole vertebral bodies, investigate the effect of endplate loading conditions on vertebral stiffness, strength, and ductility and test the hypothesis that endplate topography affects vertebral ductility and stress distributions. Eighteen vertebral bodies (T6-L3 levels; 4 female and 5 male cadavers, aged 40-98 years) were scanned using a flat panel CT system and followed with axial compression testing with Wood’s metal as filler material to maintain flat boundaries between load plates and specimens. FE models were constructed using reconstructed CT images and filler material was added digitally. Two different FE models with different filler material modulus simulating Wood’s metal and intervertebral disc (W-layer and D-layer models) were used. Element material modulus to cancellous bone was based on image gray value. Average, standard deviation, and coefficient of variation of von Mises stress in vertebral bone for W-layer and D-layer models and also the ratios of FE parameters from the two models (W/D) were calculated. Inferior and superior endplate surface topographical distribution parameters were calculated. Experimental stiffness, maximum load and work to fracture had the highest correlation with FE-calculated stiffness while experimental ductility measures had highest correlations with FE-calculated average von Mises stress and W-layer to D-layer stiffness ratio. Endplate topography of the vertebra was also associated with its structural ductility and the distribution parameter that best explained this association was kurtosis of inferior endplate topography. Our results indicate that endplate topography variations may provide insight into the mechanisms responsible for vertebral fractures. PMID:20633709
Benign notochordal cell tumors.
Martínez Gamarra, C; Bernabéu Taboada, D; Pozo Kreilinger, J J; Tapia Viñé, M
Benign notochordal cell tumors (TBCN) are lesions with notochordal differentiation which affect the axial skeleton. They are characterized by asymptomatic or non-specific symptomatology and are radiologically unnoticed because of their small size, or because they are mistaken with other benign bone lesions, such as vertebral hemangiomas. When they are large, or symptomatic, can be differential diagnosis with metastases, primary bone tumors and chordomas. We present a case of a TBCN in a 50-year-old woman, with a sacral lesion seen in MRI. A CT-guided biopsy was scheduled to analyze the lesion, finding that the tumor was not clearly recognizable on CT, so the anatomical references of MRI were used to select the appropriate plane. The planning of the approach and the radio-pathological correlation were determinant to reach the definitive diagnosis. Copyright © 2017 SERAM. Publicado por Elsevier España, S.L.U.

Degenerative disc disease is a major source of lower back pain and significantly alters the biomechanics of the lumbar spine. Dynamic stabilization device is a remedial technique which uses flexible materials to stabilize the affected lumbar region while preserving the natural anatomy of the spine. The main objective of this research work is to investigate the stiffness variation of dynamic stabilization device under various loading conditions under compression, axial rotation and flexion. Three dimensional model of the two segment lumbar spine is developed using computed tomography (CT) scan images. The lumbar structure developed is analyzed in ANSYS workbench. Two types of dynamic stabilization are considered: one with stabilizing device as pedicle instrumentation and second with stabilization device inserted around the inter-vertebral disc. Analysis suggests that proper positioning of the dynamic stabilization device is of paramount significance prior to the surgery. Inserting the device in the posterior region indicates the adverse effects as it shows increase in the deformation of the inter-vertebral disc. Analysis executed by positioning stabilizing device around the inter-vertebral disc yields better result for various stiffness values under compression and other loadings.

Vertebral osteomyelitis caused by Aspergillus nidulans is rare and usually affects immunocompromised patients. This report presents a case of thoracic vertebral osteomyelitis with epidural abscesses due to A. nidulans in a 40-year-old immunocompetent female who presented with back pain, numbness and weakness of both lower limbs. Magnetic resonance imaging demonstrated osteomyelitis involving the thoracic (T)1-T3 vertebral bodies with epidural abscesses, resulting in spinal compression. The patient underwent a decompression laminectomy of T1-T3 and debridement of the thoracic epidural inflammatory granuloma. Histopathology revealed fungal granulomatous inflammation. The patient received 6 mg/kg voriconazole every 12 h (loading dose on day 1) followed by 4 mg/kg voriconazole twice daily for 1 month, administered intravenously. The patient returned with recurrent back pain 16 months after initial presentation. A. nidulans was identified by fungal culture and polymerase chain reaction. The patient showed no evidence of recurrence 1 year after a 6-month course of oral voriconazole. The key to the effective treatment of Aspergillus osteomyelitis is not to excise the abscess, but to administer systemic antifungal drug therapy.

Of 206 patients with vertebral fractures in the thoraco-lumbar spine with spinal cord injuries, an antero-lateral decompression with stabilization of the injured segment of the vertebral column was undertaken in 56 cases. In all these cases there was a compression of the spinal cord from the front. 8 patients made a complete recovery, 31 a good recovery, and 6 were improved. In 8 patients no improvement was noted. 2 patients developed pressure sores later and 1 patient died one year after the operation of uraemia. 22 patients out of 55 got a normal function of the bladder and 25 patients out of 54 a normal function of the anal sphincter. 16 patients out of 17 made a complete or good recovery after removal of a displaced rotated vertebral bony fragment from the spinal canal, and 7 patients out of 9 with wedge shaped fractures. In our clinic today, in cases of vertebral fractures with neural involvement, reduction and internal fixation with Harrington rods and fusion of the injured segment is undertaken as soon as possible, also during the night. If narrowing of the neural canal and compression of the spinal cord are verified, a decompression operation with interbody fusion is undertaken during the next days.

To compare the clinical outcomes and complications of high viscosity and low viscosity bone cement percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCF).From September 2009 to September 2015, 100 patients with OVCF were randomly divided into 2 groups: group H, using high viscosity cement (n = 50) or group L, using low viscosity cement (n = 50). The clinical outcomes were assessed by the visual analog scale (VAS), Oswestry Disability Index (ODI), kyphosis Cobb angle, vertebral height, and complications.Significant improvements in the VAS, ODI, kyphosis Cobb angle, and vertebral height were noted in both groups, and the VAS score in the H group showed greater benefit than in the L group. Cement leakage was observed less in group H. Postoperative assessment using computed tomography identified cement leakage in 27 of 98 (27.6%) vertebrae in group H and in 63 of 86 (73.3%) vertebrae in group L (P = .025).Compared with PVP using low viscosity bone cement, PVP using high viscosity bone cement can provide the same clinical outcomes with fewer complications and is recommended for routine clinical use.

Hemangiomas are described in many locations, but breast hemangioma (BH) is rare, accounting for only 0.4% of all breast tumors. These tumors are difficult to diagnose preoperatively using conventional imaging modalities because they lack pathognomonic characteristics. Mammographic and sonographic appearances of BH were described in just a few case reports, and breast implant-related hemangiomas are even rarer. We report a case of the tumor arising in an atypical location-between the elastomer and fibrous capsule of a breast implant.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

Classification and management of hereditary retinal angiomas.
Augsburger, J J; Shields, J A; Goldberg, R E
1981-08-01
Two distinct types of retinal angiomas are currently recognized. Capillary hemangiomas occur most characteristically as part of the von Hippel-Lindau syndrome. The retinal capillary hemangiomas typically appear as globular red-orange tumors with dilated and tortuous afferent arterioles and efferent venules. Cavernous hemangiomas typically appear as grape-like clusters of dilated vascular sacs without pronounced alteration in the adjacent arterioles and venules. The spectrum of clinical features of these two types of hemangiomatosis and current approaches to management of patients with these disorders is reviewed.

To assess the sensitivity and specificity of quantitative assessment of the apparent diffusion coefficient (ADC) for differentiating benign and malignant vertebral bone marrow lesions (BMLs) and compression fractures (CFs) METHODS: An electronic literature search of MEDLINE and EMBASE was conducted. Bivariate modelling and hierarchical summary receiver operating characteristic modelling were performed to evaluate the diagnostic performance of ADC for differentiating vertebral BMLs. Subgroup analysis was performed for differentiating benign and malignant vertebral CFs. Meta-regression analyses according to subject, study and diffusion-weighted imaging (DWI) characteristics were performed. Twelve eligible studies (748 lesions, 661 patients) were included. The ADC exhibited a pooled sensitivity of 0.89 (95% confidence interval [CI] 0.80-0.94) and a pooled specificity of 0.87 (95% CI 0.78-0.93) for differentiating benign and malignant vertebral BMLs. In addition, the pooled sensitivity and specificity for differentiating benign and malignant CFs were 0.92 (95% CI 0.82-0.97) and 0.91 (95% CI 0.87-0.94), respectively. In the meta-regression analysis, the DWI slice thickness was a significant factor affecting heterogeneity (p < 0.01); thinner slice thickness (< 5 mm) showed higher specificity (95%) than thicker slice thickness (81%). Quantitative assessment of ADC is a useful diagnostic tool for differentiating benign and malignant vertebral BMLs and CFs. • Quantitative assessment of ADC is useful in differentiating vertebral BMLs. • Quantitative ADC assessment for BMLs had sensitivity of 89%, specificity of 87%. • Quantitative ADC assessment for CFs had sensitivity of 92%, specificity of 91%. • The specificity is highest (95%) with thinner (< 5 mm) DWI slice thickness.

Kyphoplasty has proved effective for durable correction of traumatic vertebral deformity following Magerl A fracture, but subsequent behavior of the adjacent discs is unclear. The objective of the present study was to analyze evolution according to severity of initial kyphosis and quality of fracture reduction. A single-center prospective study included cases of single compression fracture of the thoracolumbar hinge managed by Kyphon Balloon Kyphoplasty with polymethylmethacrylate bone cement. Radiology focused on traumatic vertebral kyphosis (VK), disc angulation (DA) and disc height index (DHI) in the adjacent discs. Linear regression assessed the correlation between superior disc height index (SupDHI) and postoperative VK on the one hand and correction gain on the other, using the Student t test for matched pairs and Pearson correlation coefficient. Fifty-two young patients were included, with mean follow-up of 18.6 months. VK fell from 13.9° preoperatively to 8.2° at last follow-up. DHI found significant superior disc subsidence (P=0.0001) and non-significant inferior disc subsidence (P=0.116). DA showed significantly reduced superior disc lordosis (P=4*10(-5)). SupDHI correlated with VK correction (r=0.32). Preoperative VK did not correlate with radiologic degeneration of the adjacent discs. Correction of traumatic vertebral deformity avoids subsidence and loss of mechanical function in the superior adjacent disc. The underlying disc compensates for residual deformity. Balloon kyphoplasty is useful in compression fracture, providing significant reduction of traumatic vertebral deformity while conserving free and healthy adjacent discs. IV.

Purpose: Vertebral compression fractures are the most common fractures in the elderly. Long lasting pain and deformity is responsible for consecutive impairment with markedly reduced life quality, increased morbidity and mortality. The beneficial effects of balloon kyphoplasty are verified in many studies. Subsequent fracture risk is not finally clarified, cement related risks and deformity related risks are discussed. There is less knowledge about the risk of bone marrow edema and new fractures during balloon kyphoplasty procedure. The goal of this study is to examine, if prone position during kyphoplasty is an independent risk factor for new fractures in the osteoporotic spine. Methods: Consecutive MRI study of 20 patients with fresh, non-traumatic thoracolumbar vertebral compression fractures and balloon kyphoplasty treatment. MRI Scans of the thoracolumbar spine were obtained after surgery, before patients have been mobilized. Specific MRI changes like new bone marrow edema, signal intensity changes in adjacent and remote segments and new fractures were assessed by specialized neuro-radiologist. Results: 20 MR images were examined within 48 hours after balloon kyphoplasty procedure. 85% did not show bone marrow edema extent changes after kyphoplasty. We found minor increase of bone marrow edema within the augmented vertebral body in 3 cases. We did not find any new bone marrow edema and no new fractures in adjacent and remote segments after balloon kyphoplasty treatment. Conclusion: Prone position leads to no new bone marrow edema and no new fractures in the osteoporotic spine. Accordingly, prone position has no risk for adjacent level fractures in osteoporotic spines. PMID:26504728

Vertebral compression fractures (VCF) cause pain and decreased physical ability, with no known well-established treatment. The aim of this study was to illuminate the experience of living with a VCF. The results show that fear and concerns are a major part of daily life. The women's initial contact with health-care providers should focus on making them feel acknowledged by offering person-centered and tailored support. In the past decade, osteoporotic-related fractures have become an increasingly common and costly public health problem worldwide. Vertebral compression fracture (VCF) is the second most common osteoporotic fracture, and patients with VCF describe an abrupt descent into disability, with a subsequent desire to regain independence in everyday life; however, little is known of their situation. The aim of this study was to illuminate the lived experience of women with an osteoporotic VCF. Ten women were interviewed during 2012-2013, starting with an open-ended question: could you tell me what it is like to live with a vertebral compression fracture? The verbatim transcribed interviews were analyzed using a phenomenological hermeneutical approach. The narrative provided descriptions of living in turmoil and chaos, unable to find stability in their life with little improvement regarding pain and physical function. Shifts from periods of constant pain to periods of fear of constant pain created a loss of confidence and an increased sense of confinement. The structural analysis revealed fear and concerns as the most prominent experience building on five themes: struggling to understand a deceiving body, breakthrough pain fueling fear, fearing a trajectory into isolation, concerns of dependency, and fearing an uncertain future. Until researchers find a successful prevention or medical/surgical treatment for osteoporotic VCFs, health-care providers and society abandon these women to remain in a painful and never ending story.

Retinal cavernous hemangioma is a rare, benign, retinal tumor characterized by angiomatous proliferation of vessels within the inner retina or the optic disc.1 Here we report a case of retinal cavernous hemangioma on the margin of the optic disc in the right eye of a 61-year-old asymptomatic female. The lesion was studied with multimodal imaging which included structural optical coherence tomography, fluorescein angiography, blue fundus auto-fluorescence, optical coherence tomography angiography (OCTA) (DRI OCT Triton; Topcon, Tokyo, Japan) and visual field examination. Blood circulation inside retinal cavernous hemangioma lesion is typically low-stagnant.2 However, OCTA demonstrated blood flow inside the lesion, illustrating its vascular circulation.3 Visual field was within the normal limits, except from a slight enlargement of the blind spot.

Sinusoidal hemangioma of the breast: diagnostic evaluation management and literature review
2017-01-01
Vascular tumors of the breast are rare and may pose a diagnostic challenge. Breast hemangioma is a very rare benign vascular neoplasm accounting for 0.4% of all breast tumors. It is most commonly detected as an incidental microscopic finding in biopsy specimens obtained for unrelated reasons. We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features. We conclude that although in carefully selected cases of breast hemangioma a conservative management with follow up imaging is a reasonable option, in cases with atypical imaging or pathological characteristics a complete surgical resection of the vascular tumor is mandatory in order to exclude the possibility of an underlying angiosarcoma.

We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features. We conclude that although in carefully selected cases of breast hemangioma a conservative management with follow up imaging is a reasonable option, in cases with atypical imaging or pathological characteristics a complete surgical resection of the vascular tumor is mandatory in order to exclude the possibility of an underlying angiosarcoma.

We report an unusual presentation of an orbital cavernous hemangioma in a 26-year-old female, who noted sudden redness and swelling of the left eye (LE) on waking up. At presentation, upper eyelid edema with periorbital ecchymosis and subconjunctival hemorrhage were noted in the LE. Although there was transient symptomatic relief with topical medications, blurring of vision developed in the LE. When seen 10 days later, the patient’s LE showed axial proptosis. Magnetic resonance imaging revealed an intraconal soft tissue mass in the superomedial quadrant of the left orbit. Superior orbitotomy with mass excision was done; histopathological examination of the excised mass revealed a cavernous hemangioma. The patient had complete visual recovery following surgery. To our knowledge, an acute presentation of an orbital cavernous hemangioma with subconjunctival hemorrhage and periorbital ecchymosis has not previously been reported. PMID:28769595

Cavernous hemangiomas of penis are rare benign lesions infrequently described in the literature. No completely satisfactory treatment has been found to correct the cosmetic deformities especially the extensive hemangiomas of corpus penis. In light of the promising application of copper wire/needle in vascular malformations, we began a clinical study to investigate the safety, feasibility, and cosmetic effect of copper wire therapy in treating cavernous hemangioma of penis. Seven patients ranging in age from 12 to 32 years with penile cavernous hemangiomas entered our study from 2005 to 2011. All patients received treatments with percutaneous copper wires. Perioperative data including mean operation time, estimated blood loss, length of copper wire retention, and length of hospital stay were analyzed. All possible complications were noted, and cosmetic result was evaluated. Patients were followed up after discharge from the hospital. All operations were successful, and no obvious complications were observed. The patients were satisfied with the aesthetic results. Follow-up time ranged from 1 to 5 years. Recurrence was discovered in a patient with the largest lesion of corpus penis 2 months after the treatment. Secondary procedure was carried out with the same technique, and no lesions were found later. The shortage of studies on this topic prevented us from defining a therapeutic reference standard. The results of our study confirmed that copper wire therapy was a simple, safe, and useful option for penile cavernous hemangioma. © 2013 International Society for Sexual Medicine.

To reclassify facial nerve hemangiomas in the context of presently accepted vascular lesion nomenclature by examining histology and immunohistochemical markers. Cohort analysis of patients diagnosed with a facial nerve hemangioma between 1990 and 2008. Collaborative analysis at a specialty hospital and a major academic hospital. Seven subjects were identified on composite review of office charts, a pathology database spanning both institutions, and an encrypted patient registry. Clinical data were compiled, and hematoxylin-eosin-stained specimens were reviewed. For six patients, archived pathological tissue was available for immunohistochemical evaluation of markers specific for infantile hemangioma (glucose transporter protein isoform 1 [GLUT1] and Lewis Y antigen) and for lymphatic endothelial cells (podoplanin). All patients clinically presented with slowly progressive facial weakness at a mean age of 45 years without prior symptomatology. Hemotoxylin-eosin-stained histopathological slides showed irregularly shaped, dilated lesional vessels with flattened endothelial cells, scant smooth muscle, and no internal elastic lamina. Both podoplanin staining for lymphatic endothelial cells and GLUT1 and LewisY antigen staining for infantile hemangioma endothelial cells were negative in lesional vessels in all specimens for which immunohistochemical analysis was performed. Lesions of the geniculate ganglion historically referred to as "hemangiomas" do not demonstrate clinical, histopathological, or immunohistochemical features consistent with a benign vascular tumor, but instead are consistent with venous malformation. We propose that these lesions be classified as "venous vascular malformations of the facial nerve." This nomenclature should more accurately predict clinical behavior and guide therapeutic interventions.

Infantile hemangiomas are well known for their rapid growth during the first 6 to 9 months of life, followed by a spontaneous but slow involution. The standard of care is to treat these lesions at an early age with propranolol to expedite the involution process; however, surgery still remains an active component in the management. Medical treatment with propranolol or natural involution will often result in residual telangiectasias. We evaluated the efficacy of using a diode laser as a treatment for telangiectasias following cervicofacial infantile hemangioma involution. Case series with chart review. Tertiary care hospital and practice specializing in the care of vascular anomalies. Twenty patients, aged 4 months to 11 years (average 2.69 years), underwent treatment with a 532-nm diode laser to treat the residual telangiectasias following hemangioma involution. All procedures were performed in the operating room. To assess the efficacy, we independently evaluated pre- and posttreatment digital photographs and ranked them on a 0- to 4-point scale (0 = no change and 4 = complete response). Adverse reactions were also recorded. The telangiectasias showed considerable improvement following treatment. In more than half of the patients treated, the affected area demonstrated a complete response. No adverse reactions were noted. A 532-nm diode laser effectively treats the remaining telangiectasias following hemangioma involution. Whether used independently or in conjunction with other treatment modalities, the diode laser should be part of the surgical armamentarium when treating infantile hemangiomas. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Developing fusionless devices to treat pediatric scoliosis necessitates lengthy and expensive animal trials. The objective was to develop and validate a porcine spine numerical model as an alternative platform to assess fusionless devices. A parametric finite element model (FEM) of an osseoligamentous porcine spine and rib cage, including the epiphyseal growth plates, was developed. A follower-type load replicated physiological and gravitational loads. Vertebral growth and its modulation were programmed based on the Hueter-Volkmann principle, stipulating growth reduction/promotion due to increased compressive/tensile stresses. Scoliosis induction via a posterior tether and 5-level rib tethering, was simulated over 10 weeks along with its subsequent correction via a contralateral anterior custom tether (20 weeks). Scoliosis induction was also simulated using two experimentally tested compression-based fusionless implants (hemi- and rigid staples) over 12- and 8-weeks growth, respectively. Resulting simulated Cobb and sagittal angles, apical vertebral wedging, and left/right height alterations were compared to reported studies. Simulated induced Cobb and vertebral wedging were 48.4° and 7.6° and corrected to 21° and 5.4°, respectively, with the contralateral anterior tether. Apical rotation (15.6°) was corrected to 7.4°. With the hemi- and rigid staples, Cobb angle was 11.2° and 11.8°, respectively, with 3.7° and 2.0° vertebral wedging. Sagittal plane was within the published range. Convex/concave-side vertebral height difference was 3.1 mm with the induction posterior tether and reduced to 2.3 with the contralateral anterior tether, with 1.4 and 0.8 for the hemi- and rigid staples. The FEM represented growth-restraining effects and growth modulation with Cobb and vertebral wedging within 0.6° and 1.9° of experimental animal results, while it was within 5° for the two simulated staples. Ultimately, the model would serve as a time- and cost-effective tool to assess the biomechanics and long-term effect of compression-based fusionless devices prior to animal trials, assisting the transfer towards treating scoliosis in the growing spine.

Lumbar spine geometry, density and indices of bone strength were assessed relative to menarche status, using artistic gymnastics exposure during growth as a model of mechanical loading. Paired posteroanterior (PA) and supine lateral (LAT) DXA scans of L3 for 114 females (60 ex/gymnasts and 54 non-gymnasts) yielded output for comparison of paired (PALAT) versus standard PA and LAT outcomes. BMC, areal BMD, vertebral body dimensions, bone mineral apparent density (BMAD), axial compressive strength (IBS) and a fracture risk index were evaluated, modeling vertebral body geometry as an ellipsoid cylinder. Two-factor ANCOVA tested statistical effects of gymnastic exposure, menarche status and their interaction, adjusting for age and height as appropriate. Compared to non-gymnasts, ex/gymnasts exhibited greater PABMD, PABMC, PAWIDTH, PA CROSS-SECTIONAL AREA (CSA), PAVOLUME, LATBMD, LATBMAD, PALATCSA and PALATIBS (p<0.05). Non-gymnasts exhibited greater LATDEPTH/PAWIDTH, LATBMC/PABMC, LATVHEIGHT, LATAREA and Fracture Risk Index. Using ellipsoid vertebral geometric models, no significant differences were detected for PA or PALAT BMAD. In contrast, cuboid model results (Carter 1992) suggested erroneous ex/gymnast PABMAD advantages, resulting from invalid assumptions of proportional variation in linear skeletal dimensions. Gymnastic exposure was associated with shorter, wider vertebral bodies, yielding greater axial compressive strength and lower fracture risk, despite no BMAD advantage. Our results suggest the importance of plane-specific vertebral geometric adaptation to mechanical loading during growth. Paired scan output provides a more accurate assessment of this adaptation than PA or LAT plane scans alone. PMID:21839871

Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare. We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.

Finite element analysis (FEA) is an advanced computer technique of structural stress analysis developed in engineering mechanics. Because the compressive behavior of vertebral bone shows nonlinear behavior, a nonlinear FEA should be utilized to analyze the clinical vertebral fracture. In this article, a computed tomography-based nonlinear FEA (CT/FEA) to analyze the vertebral bone strength, fracture pattern, and fracture location is introduced. The accuracy of the CT/FEA was validated by performing experimental mechanical testing with human cadaveric specimens. Vertebral bone strength and the minimum principal strain at the vertebral surface were accurately analyzed using the CT/FEA. The experimental fracture pattern and fracture location were also accurately simulated. Optimization of the element size was performed by assessing the accuracy of the CT/FEA, and the optimum element size was assumed to be 2 mm. It is expected that the CT/FEA will be valuable in analyzing vertebral fracture risk and assessing therapeutic effects on osteoporosis. PMID:26029476
[Infantile hemangioma and propranolol: a therapeutic "revolution". Literature review].

Infantile hemangioma (IH) is the most common benign vascular tumour affecting children. Most infantile hemangiomas are self-limiting, but some require specific treatment. Propranolol has been proposed for the treatment of infantile hemangiomas. The aim of this study is to explore the mechanism of action of propranolol for the treatment of infantile hemangiomas and to demonstrate its safety and efficacy through a review of the literature. The non cardioselective bêta-blocker propranolol has been used in a pediatric setting for 40 years and, since 2008, has a new indication. A clearly significant improvement has been observed in the condition of children with complicated IH (10%) treated with propranolol. This new indication has been widely described in the international literature. Various explanations have been put forward for the mechanism of action including a vasoconstrictor, antiangiogenic and apoptotic effect of propranolol on the different cells making up an IH. Overall tolerance is good and the efficacy markedly superior to that of any other treatments used for this purpose. In conclusion, with its good tolerance profile and superior efficacy versus all the other available therapies, propranolol can be considered to be a first-line treatment for complicated IH.

This study established gender-specific reference values in mainland Chinese (MC) and is important for quantitative morphometry for diagnosis and epidemiological study of osteoporotic vertebral compressive fracture. Comparisons of reference values among different racial populations are then performed to demonstrate the MC-specific characteristic. Osteoporotic vertebral compressive fracture (OVCF) is a common complication of osteoporosis in the elder population. Clinical diagnosis and epidemiological study of OVCF often employ quantitative morphometry, which relies heavily on the comparison of patients' vertebral parameters to existing reference values derived from the normal population. Thus, reference values are crucial in clinical diagnosis. To our knowledge, this is the first study to establish reference values of the mainland Chinese (MC) for quantitative morphometry. Vertebral heights including anterior (Ha), middle (Hm), posterior (Hp) heights, and predicted posterior height (pp) from T4 to L5 were obtained; and ratios of Ha/Hp, Hm/Hp and Hp/pp. were calculated from 585 MC (both female and male) for establishing reference values and subsequent comparisons with other studies. Vertebral heights increased progressively from T4 to L3 but then decreased in L4 and L5. Both genders showed similar ratios of vertebral dimensions, but male vertebrae were statistically larger than those of female (P < 0.01). Vertebral size of MC population was smaller than that of US and UK population, but was surprisingly larger than that of Hong Kong Chinese, although these two are commonly considered as one race. Data from different racial populations showed similar dimensional ratios in all vertebrae. We established gender-specific reference values for MC. Our results also indicated the necessity of establishing reference values that are not only race- and gender-specific, but also population- or region-specific for accurate quantitative morphometric assessment of OVCF.

Artificial materials reflecting the mechanical properties of human bone are essential for valid and reliable implant testing and design. They also are of great benefit for realistic simulation of surgical procedures. The objective of this study was therefore to characterize two groups of self-developed synthetic foam structures by static compressive testing and by microcomputed tomography. Two mineral fillers and varying amounts of a blowing agent were used to create different expansion behavior of the synthetic open-cell foams. The resulting compressive and morphometric properties thus differed within and also slightly between both groups. Apart from the structural anisotropy, the compressive and morphometric properties of the synthetic foam materials were shown to mirror the respective characteristics of human vertebral trabecular bone in good approximation. In conclusion, the artificial materials created can be used to manufacture valid synthetic bones for surgical training. Further, they provide novel possibilities for studying the relationship between trabecular bone microstructure and biomechanical properties. Copyright © 2017 Elsevier B.V. All rights reserved.
Acquired Elastotic Hemangioma: Case Series and Comprehensive Literature Review
Hinds, Brian R
2017-01-01
Background Acquired elastotic hemangioma is a benign vascular proliferation that typically presents as an asymptomatic red plaque on a sun-exposed site of an adult. Material and Methods The PubMed database was used to search the following words: acquired, angioma, arm, basal, carcinoma, cell, elastosis, elastotic, exposed, forearm, hemangioma, solar, sun, and vascular. The relevant papers and reference cited generated by the search were reviewed. The features from a case series of 11 patients with acquired elastotic hemangioma are presented. In addition, a comprehensive review of the characteristics of this unique hemangioma—not only in our 11 patients but also in the previously reported 34 individuals with this lesion—is provided. Results Acquired elastotic hemangioma, reported in 45 patients (24 women and 21 men), typically appeared as an asymptomatic solitary red plaque in sun-exposed areas—most commonly the forearm--of adults aged 50 years or older. The pathology shows a proliferation of vascular channels—surrounded and intertwined by intense solar elastosis--in the upper dermis, located parallel to the overlying epidermis, and separated from it by a zone of normal-appearing superficial papillary dermis. There was extensive solar elastosis surrounding and between the new blood vessels; some of the endothelial cells protrude (in a hob-nail pattern) into the vessel lumen. The clinical differential diagnosis includes basal cell carcinoma and the pathologic differential diagnosis includes other benign, malignant, and reactive vascular lesions. Ultraviolet radiation may contribute to the pathogenesis of this hemangioma since it occurs on sun-exposed sites. There was no recurrence of the lesion following either excision or observation. Conclusions The possibility of acquired elastotic hemangioma should be considered by clinicians when they encounter an older individual with a new red plaque on a sun-exposed site that clinically appears to be a superficial basal cell carcinoma.

A 52-year-old woman complained of the sudden onset of a left temporal headache, left neck stiffness and dizziness. Brain magnetic resonance imaging showed a high-intensity lesion in the right medial medulla. Dynamic cerebral angiography revealed vertebral artery dissection and compression at the C6 level due to a transverse process at the C6 level associated with rightward head rotation. Removal of bone and decompression of the vertebral artery were performed from the C5 to C6 levels. Intraoperasively, obstruction of blood flow due to a laryngeal cartilage that rotated with the passive rotation of the patient's head to the right was found. To the best of our knowledge this is the first reported case of vertebral artery occlusion due to a laryngeal cartilage associated with head rotation.

Thyroid hemangioma is benign and associated with fine-needle aspiration (FNA) biopsy or trauma in most cases. Its differential diagnosis is very difficult. We presented the case of a 48-year-old man complained of slowly progressed swelling in the anterior neck for 20 years. Ultrasound and CT scan revealed a hypoechogenic and heterogeneous mass measuring 4 × 3.5 cm located in the right lobe of thyroid gland. Postoperative pathological and immunohistochemical examinations of the surgical specimen revealed a primary hemangioma of the thyroid gland. The patient received a right lobectomy of the thyroid. The patient had been followed up for 10 months after surgery without complications and remained asymptomatic. Primary thyroid hemangioma should be considered when there is a well-circumscribed capsule mass on medical imaging without history of FNA or any other cervical procedures or trauma.

This study explored the feasibility and clinical efficacy of expanded flap to repair facial scar left by radiotherapy of hemangioma. From March 2000 to April 2011, 13 cases of facial cicatrices left by radiotherapy of hemangioma have been treated with implantation surgery of facial skin dilator under local anesthesia. After water flood expansion for 1-2 months, resection of facial scar was performed, and wound repairing with expansion flap transfer was done. Thirteen patients were followed up from 5 months to 3 years. All patients tolerated flap transfer well; no contracture occurred during the facial expansion flap transfer. The incision scar was not obvious, and its color and texture were identical to surrounding skin. In conclusion, the use of expanded flap transfer to repair the facial scar left by radiotherapy of hemangioma is advantageous due to its simplicity, flexibility, and large area of repairing. This method does not affect the subsequent facial appearance.

2009-11-01
Pulmonary sclerosing hemangioma (PSH) is an uncommon benign tumor that presents as a solitary asymptomatic and slow-growing nodule. It occurs in both young and old persons; peak incidence is in the fifth decade. Both sexes are affected by this tumor, but women more frequently than men. On histological examination, PSH shows prominent sclerotization and vascularization of the tissue. Recent studies conclude that PSH derives from type II pneumocytes, but the potential for progression and histogenesis remains controversial. We report a case of pulmonary sclerosing hemangioma in a 61-year-old woman with a neoplastic node 1 cm in diameter. The karyotype was 46,XX,t(8;18),der(14;15),+14 in all the cells analyzed. PTEN (10q23) and IgH (14q32) probes were analyzed in interphase nuclei and paraffin-embedded tissues of tumor cells. These chromosome abnormalities could provide information about the relationship of genetic changes to the biological properties of sclerosing hemangioma tumors.

Rib fractures are one of main causes of chest or flank pain when related to an osteoporotic vertebral compression fracture (OVCF). The authors investigated the incidence and risk factors of rib fracture in 284 patients with OVCF using bone scans and evaluated the feasibility as to whether bone scans could be utilized as a useful screening tool. Hot uptake lesions on ribs were found in 122 cases (43.0%). The factors analyzed were age, sex, number and locations of fractured vertebrae, BMD, and compression rates as determined using initial radiography. However, no statistical significances were found. In 16 cases (5.6%), there were concurrent multiple fractures of both the thoracic and lumbar spines not detected by single site MRI. Sixty cases (21.1%) of OVCF with the a compression rate of less than 15% could not be identified definitely by initial plain radiography, but were confirmed by bone scans. It is concluded that a bone scan has outstanding ability for the screening of rib fractures associated with OVCF. Non-adjacent multiple fractures in both thoracic and lumbar spines and fractures not identified definitely by plain radiography were detected on bone scans, which provided a means for determining management strategies and predicting prognosis.
Biomechanics of Thoracolumbar Burst and Chance-Type Fractures during Fall from Height
Ivancic, Paul C.
2014-01-01
Study Design In vitro biomechanical study. Objective To investigate the biomechanics of thoracolumbar burst and Chance-type fractures during fall from height. Methods Our model consisted of a three-vertebra human thoracolumbar specimen (n = 4) stabilized with muscle force replication and mounted within an impact dummy. Each specimen was subjected to a single fall from an average height of 2.1 m with average velocity at impact of 6.4 m/s. Biomechanical responses were determined using impact load data combined with high-speed movie analyses. Injuries to the middle vertebra of each spinal segment were evaluated using imaging and dissection. Results Average peak compressive forces occurred within 10 milliseconds of impact and reached 40.3 kN at the ground, 7.1 kN at the lower vertebra, and 3.6 kN at the upper vertebra. Subsequently, average peak flexion (55.0 degrees) and tensile forces (0.7 kN upper vertebra, 0.3 kN lower vertebra) occurred between 43.0 and 60.0 milliseconds. The middle vertebra of all specimens sustained pedicle and endplate fractures with comminution, bursting, and reduced height of its vertebral body. Chance-type fractures were observed consisting of a horizontal split fracture through the laminae and pedicles extending anteriorly through the vertebral body. Conclusions We hypothesize that the compression fractures of the pedicles and vertebral body together with burst fracture occurred at the time of peak spinal compression, 10 milliseconds. Subsequently, the onset of Chance-type fracture occurred at 20 milliseconds through the already fractured and weakened pedicles and vertebral body due to flexion-distraction and a forward shifting spinal axis of rotation.

Hemangioma and vascular malformations in the field of oral and maxillofacial surgery is a pathology more often found in recent years in patients. The aim of this study was to evaluate the efficacy of the laser photocoagulation performed with a diode laser (Ga-Al-As) 980 nm wavelength in the treatment of vascular lesions which are located on the oral and maxillofacial areas, using color Doppler ultrasonography for evaluation of the results. We also made a comparison between laser therapy and sclerotherapy in order to establish treatment protocols and recommendations associated with this pathology. We conducted a controlled study on a group of 92 patients (38 male and 54 female patients, with an average age of 36 years) having low flow hemangioma and vascular malformations. Patients in this trial received one of the methods of treatment for vascular lesions such as hemangioma and vascular malformations: laser therapy or sclerotherapy. After laser therapy we have achieved a reduction in size of hemangioma and vascular malformations treated with such a procedure, and the aesthetic results were favorable. No reperfusion or recanalization of laser treated vascular lesions was observed after an average follow-up of 6 to 12 months. In case of sclerotherapy a reduction in the size of vascular lesions was also obtained. The 980 nm diode laser has been proved to be an effective tool in the treatment of hemangioma and vascular malformations in oral and maxillofacial area. Laser therapy in the treatment of vascular lesions was more effective than the sclerotherapy procedure.

There have been reports of the use of levothyroxine or levothyroxine plus liothyronine for consumptive hypothyroidism caused by hepatic hemangiomas. Administration of levothyroxine without liothyronine can be inadequate to maintain normal levels of both free T3 and free T4 in some patients. However, there is no report of treatment with liothyronine plus propranolol. We herein present a case in which we used liothyronine therapy for multifocal hepatic hemangiomas in a Japanese patient with low free T3 and normal free T4 levels. A 2-month-old Japanese male was referred to our hospital because of jaundice. Abdominal computed tomography showed multifocal hemangiomas in both lobes of the liver. TSH level was elevated, free T3 level was low, free T4 level was normal, and hypothyroidism due to hepatic hemangiomas was diagnosed. In addition to propranolol, liothyronine was started. We used liothyronine without levothyroxine for hypothyroidism because only free T3 level had decreased, whereas free T4 level remained in the normal range. The TSH and free T3 levels normalized in this patient in less than 1 month. The liothyronine dose was gradually reduced with regression of the hemangiomas, and liothyronine administration was discontinued at the age of 5 months. At the age of 11 months, growth and neurological development of the patient met age-specific norms, and he was euthyroid at that time. This is the first report demonstrating the use of liothyronine with propranolol for treatment of this type of consumptive hypothyroidism.

FABP4 is widely expressed in both normal and pathologic tissues. It promotes cell proliferation, survival and migration of endothelial cells, and therefore, angiogenesis. However, the role of FABP4 in hemangioma or hemangioma endothelial cells (HemECs) has not been explored. In this study, we investigated whether FABP4 directly regulates the proliferation of HemECs. The expression of cell cycle checkpoint genes was analyzed with the microarray data of human dermal microvascular endothelial cells (HDVECs) and infantile hemangioma endothelial cells. Real-time RT-PCR and western blotting were used to examine the expression of FABP4 in HemECs. Next, the FABP4 expression was inhibited in HemECs using siRNA or rapamycin and upregulated using retroviral transduction of HemECs to assess its influence on proliferation of HemECs. The microarray data showed that cell cycle checkpoint genes were upregulated in HemECs. Moreover, HemECs showed significantly higher proliferation rates than HDVECs. The expression of FABP4 and mTOR was increased in the HemECs. While FABP4 knockdown reduced the BrdU incorporation and cell number of HemECs as expected, cell proliferation was accelerated by FABP4 over-expression. Moreover, rapamycin (10nM) inhibited mTOR-FABP4 signaling and HemEC proliferation. Taken together, these results indicated that mTOR signaling pathway-activated FABP4 directly regulates the proliferation of endothelial cells in hemangioma. Rapamycin and inhibitors of FABP4 have therapeutic potential for treating infantile hemangiomas. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Cavernous hemangiomas of the uterus are rare benign vascular lesions. Nine cases of diffuse cavernous hemangioma of the gravid uterus have been reported, most of which diffusely involved the myometrium. These vascular malformations are clinically significant, and may cause pronounced bleeding resulting in maternal or fetal demise. Thrombosis of cavernous hemangiomas of the uterus has been previously reported. We here report the first case in which a thrombosed cavernous hemangioma of the myometrium resulted in a fatal pulmonary embolism in a post-partum woman. A 25-year-old obese African-American woman who had one pregnancy and was delivered of twins by cesarean section was admitted 1 week after the successful delivery. The 12-day clinical course included ventilator-dependent respiratory failure, systemic hypertension, methicillin-resistant Staphylococcus aureus in the sputum, leukocytosis and asystole. A transabdominal ultrasound examination showed heterogeneous thickened and irregular products in the endometrial canal. The laboratory values were relevant for an increased prothrombin time, activated partial thromboplastin time, ferritin and a decrease in hemoglobin. The clinical cause of death was cited as acute respiratory distress syndrome. At autopsy, a 400g spongy, hemorrhagic uterus with multiple cystic spaces measuring approximately 0.5 × 0.4cm filled with thrombi within the myometrium was identified. Immunohistological examination with a CD31 stain for vascular endothelium associated antigen confirmed several endothelium-lined vessels, some of which contained thrombi. These histological features were consistent with cavernous hemangioma of the myometrium. A histological examination of the lungs revealed multiple fresh thromboemboli in small- and medium-sized pulmonary arteries in the right upper and lower lobes without organization, but with adjacent areas of fresh hemorrhagic infarction. This case underscores the importance of a high index of suspicion in a pregnant or post-partum woman presenting with respiratory symptoms. Thrombosis of the cavernous hemangiomas of the gravid or post-partum uterus is a rare entity. This case is of interest because it indicates that this condition can be fatally complicated by embolization of the thrombi in the cavernous myometrial hemangiomas. Although delivery by conservative methods, as well as cesarean section, is possible without resorting to hysterectomy, occasionally, the consequences could be fatal as in this case.

The clinical effects of two different methods-high-viscosity cement percutaneous vertebroplasty (PVP) and low-viscosity cement percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCFs) were investigated. From June 2010 to August 2013, 98 cases of OVCFs were included in our study. Forty-six patients underwent high-viscosity PVP and 52 patients underwent low-viscosity PKP. The occurrence of cement leakage was observed. Pain relief and functional activity were evaluated using the Visual Analog Scale (VAS) and Oswestry Disability Index (ODI), respectively. Restoration of the vertebral body height and angle of kyphosis were assessed by comparing preoperative and postoperative measurements of the anterior heights, middle heights and the kyphotic angle of the fractured vertebra. Nine out of the 54 vertebra bodies and 11 out of the 60 vertebra bodies were observed to have cement leakage in the high-viscosity PVP and low-viscosity PKP groups, respectively. The rate of cement leakage, correction of anterior vertebral height and kyphotic angles showed no significant differences between the two groups (P>0.05). Low-viscosity PKP had significant advantage in terms of the restoration of middle vertebral height as compared with the high-viscosity PVP (P<0.05). Both groups showed significant improvements in pain relief and functional capacity status after surgery (P<0.05). It was concluded that high-viscosity PVP and low-viscosity PKP have similar clinical effects in terms of the rate of cement leakage, restoration of the anterior vertebral body height, changes of kyphotic angles, functional activity, and pain relief. Low-viscosity PKP is better than high-viscosity PVP in restoring the height of the middle vertebra.
Circumscribed choroidal hemangioma: A case report and literature review.
Berry, Morgan; Lucas, Linda J H
Choroidal hemangioma is a rare congenital ocular tumor that can present as either circumscribed or diffuse. Circumscribed choroidal hemangioma (CCH) typically manifests as a red-orange mass within the posterior pole and appears similar to other ocular conditions, such as choroidal melanoma and choroidal metastasis. Proper diagnosis is crucial and is aided by the use of ancillary testing. CCH itself is benign but can cause secondary complications such as subretinal fluid accumulation and subsequent retinal detachment. If these conditions should arise, several treatment options are available. Published by Elsevier España, S.L.U.

Various etiologies of spontaneous hemothorax have been reported, though the cause remains unidentified in some patients despite an exploratory thoracotomy. We report on an 89-year-old man with spontaneous hemothorax resolved by partial resection of the lung using complete video-assisted thoracoscopic surgery. The histopathologic findings revealed a ruptured micro-venous hemangioma located just below the bleeding visceral pleura. To the best of our knowledge, this is the first report of spontaneous hemothorax caused by a pulmonary micro-venous hemangioma. Copyright © 2015 The Society of Thoracic Surgeons.

We report a rare case of congenital tri-cavernous hemangiomas of the right buccal region, right accessory parotid gland, and masseter muscle region in an adult. The patient, a 25-year-old woman, complained of 3 masses in her right midcheek. Ultrasonographic and computed tomographic findings showed an irregular-shaped mass (multiple calcifications) with a well-defined margin in the masseter muscle region, an ellipse-shaped mass (multiple calcifications) with a well-defined margin in the right buccal region, and a comma-shaped mass (no calcifications) with a well-defined margin separate from the parotid gland in the right accessory parotid gland region. These iconographic findings suggested that the masses were all hemangiomas separately originating from the parotid gland, accessory parotid gland, and masseter muscle. The masses were completely removed through a standard parotid incision without postoperative facial palsy, skin deformity, and difficulty in secreting saliva. Findings from histologic examination of the tumor revealed multiple, thin-walled, and dilated blood vessels, confirming the diagnosis of cavernous hemangiomas. Ultrasonographic and computed tomographic findings were extremely useful in diagnosing the mass/masses as hemangioma before surgery, clarifying relationships between the mass and adjacent structures, and determining the surgical approach to the mass/masses.
A rare case of pure primary hemangioma of the scapula: A case report
LI, WEI; ZOU, FAN; DAI, MIN; ZHANG, BIN; NIE, TAO
2015-01-01
Hemangioma is a benign vascular tumor, which may occur in any bone of the body. The most common locations are the spine and craniofacial bone; however, occurrence is extremely rare in the scapula. The current study presented the case of a 58-year-old female, with scapula hemangioma in the left shoulder who presented with joint ache that had lasted for ~1 year. The main clinical manifestations included local tenderness, an osseous lump and limited shoulder movement with a little pain, which was alleviated by rest. Roentgenogram, computed tomography and magnetic resonance imaging of the left acromion revealed a mass along the inner surface of the scapula of the left shoulder with polycystic expansion and bone destruction. The results of computed tomography and magnetic resonance imaging indicated a pure primary tumor and the lesion was subsequently resected. Notably, the postoperative pathological diagnosis was capillary hemangioma. The aim of the present study was to analyze the clinical and imaging features of scapula hemangioma, which must be considered for the differential diagnosis of scapula tumors. In the present case, no recurrence was identified by X-ray examination 1 year after surgery. The long-term efficacy of surgical treatment requires continuous observation of the patient. PMID:26622831
Vertebral Compression Fractures after Lumbar Instrumentation.
Granville, Michelle; Berti, Aldo; Jacobson, Robert E
2017-09-29
Lumbar spinal stenosis (LSS) is primarily found in an older population. This is a similar demographic group that develops both osteoporosis and vertebral compression fractures (VCF). This report reviewed a series of patients treated for VCF that had previous lumbar surgery for symptomatic spinal stenosis. Patients that only underwent laminectomy or fusion without instrumentation had a similar distribution of VCF as the non-surgical population in the mid-thoracic, or lower thoracic and upper lumbar spine. However, in the patients that had previous short-segment spinal instrumentation, fractures were found to be located more commonly in the mid-lumbar spine or sacrum adjacent to or within one or two spinal segments of the spinal instrumentation. Adjacent-level fractures that occur due to vertebral osteoporosis after long spinal segment instrumentation has been discussed in the literature. The purpose of this report is to highlight the previously unreported finding of frequent lumbar and sacral osteoporotic fractures in post-lumbar instrumentation surgery patients. Important additional factors found were lack of preventative medical treatment for osteoporosis, and secondary effects related to inactivity, especially during the first year after surgery.
Fat embolism syndrome following percutaneous vertebroplasty: a case report.
Ahmadzai, Hasib; Campbell, Scott; Archis, Constantine; Clark, William A

Vertebroplasty is commonly performed for management of pain associated with vertebral compression fractures. There have been two previous reports of fatal fat embolism following vertebroplasty. Here we describe a case of fat embolism syndrome following this procedure, and also provide fluoroscopic video evidence consistent with this occurrence. The purpose of this study was to review the literature and report a case of fat embolism syndrome in a patient who underwent percutaneous vertebroplasty for compression fracture. The study design for this manuscript was of a clinical case report. A 68-year-old woman who developed sudden back pain with minimal trauma was found to have a T6 vertebral compression fracture on radiographs and bone scans. Percutaneous vertebroplasty of T5 and T6 was performed. Fluoroscopic imaging during the procedure demonstrated compression and rarefaction of the fractured vertebra associated with changes in intrathoracic pressure. Immediately after the procedure, the patient's back pain resolved and she was discharged home. Two days later, she developed increasing respiratory distress, confusion, and chest pain. A petechial rash on her upper arms also appeared. No evidence of bone cement leakage or pulmonary filling defects were seen on computed tomography-pulmonary angiography. Brain magnetic resonance imaging demonstrated hyperintensities in the periventricular and subcortical white matter on T2/fluid-attenuated inversion recovery sequences. A diagnosis of fat embolism syndrome was made, and the patient recovered with conservative management. Percutaneous vertebroplasty is a relatively safe and simple procedure, reducing pain and improving functional limitations in patients with vertebral fractures. This case demonstrates an uncommon yet serious complication of fat embolism syndrome. Clinicians must be aware of this complication when explaining the procedure to patients and provide prompt supportive care when it does occur. Copyright © 2014 Elsevier Inc. All rights reserved.

Infantile hemangioma (IH) is the most common vascular tumor in children. It is controversial whether IHs has effects on the quality of life (QOL) in patients of whom IH poses no threat or potential for complication. Thus, we conducted this study to evaluate the q QOL in patients with IH and find the predictors of poor QOL. The PedsQL 4.0 Genetic Core Scales and the PedsQL family information form were administered to parents of children with IH and healthy children both younger than 2-year-old. The quality-of-life instrument for IH (IH-QOL) and the PedsQL 4.0 family impact module were administered to parents of children with IH. We compared the PedsQL 4.0 Genetic Core Scales (GCIS) scores of the two groups. Multiple step-wise regression analysis was used to determine factors that influenced QOL in children with IH and their parents. Except for physical symptom, we found no significant difference in GCIS between patient group and healthy group (P = 0.409). The internal reliability of IH-QOL was excellent with the Cronbach's alpha coefficient for summary scores being 0.76. Multiple step-wise regression analysis showed that the predictors of poor IH-QOL total scores were hemangioma size, location, and mother's education level. The predictors of poor FIM total scores were hemangioma location and father's education level. The predictors of poor GCIS total scores were children's age, hemangioma location and father's education level. The findings support the feasibility and reliability of the Chinese version of IH-QOL to evaluate the QOL in children with IH and their parents. Hemangioma size, location and education level of mother are important impact factors for QOL in children with IH and their parents.

To explore the efficacy and safety of imiquimod 5% cream as a treatment for infantile hemangioma. Phase II, open-label, noncomparative study of imiquimod applied during 16 weeks, with posttherapy follow-up 16 weeks later (8 months total). Outpatient pediatric tertiary care referral center in Quebec, Canada. Healthy infants up to 8.8 months of age with previously untreated, nonulcerated, proliferative superficial or mixed infantile hemangioma, excluding periorbital, or perineal localization, > or =100 cm2 in size. Topical imiquimod applied three to seven times per week for 16 weeks to infantile hemangioma. Lesion area, volume, depth (Doppler ultrasound), and color (erythema), serum drug, and interferon-alpha levels. Sixteen infants (11 girls, 5 boys) with a mean age at entry of 4.1 months and mean lesion area of 32.89 cm2, and volume of 39.98 cm3 were enrolled. Two participants discontinued treatment early, one for an adverse event (crying upon application), the other because of the lack of compliance. Local skin reactions were consistent with those reported in adults. Two cases had a decrease and three had an increase in lesion parameters; otherwise no meaningful changes in lesion area, volume, or depth were observed. At the 4-month posttreatment visit, 11 of 14 subjects had improvement in erythema (marginal homogeneity test = 2.668, p = 0.008). Measured serum drug and interferon-alpha levels were low or undetectable. Treatment of infants with infantile hemangioma with imiquimod up to seven times per week for 16 weeks was generally well tolerated with low systemic exposure. Improvement was observed in hemangioma coloration, but not lesion size, suggesting effects were limited to the superficial component.
The role of physical activity in bone health: a new hypothesis to reduce risk of vertebral fracture.
Sinaki, Mehrsheed
2007-08-01
Locomotion has always been a major criterion for human survival. Thus, it is no surprise that science supports the dependence of bone health on weight-bearing physical activities. The effect of physical activity on bone is site-specific. Determining how to perform osteogenic exercises, especially in individuals who have osteopenia or osteoporosis, without exceeding the biomechanical competence of bone always poses a dilemma and must occur under medical advice. This article presents the hypothesis that back exercises performed in a prone position, rather than a vertical position, may have a greater effect on decreasing the risk for vertebral fractures without resulting in compression fracture. The risk for vertebral fractures can be reduced through improvement in the horizontal trabecular connection of vertebral bodies.

To investigate the clinical effect of 1% lauromacrogol for the treatment of facial refractory hemangioma and vascular malformation. From Sept 2009 to Nov 2011, 55 patients (20 male, 35 female, 1 month to 30 years) with different types of facial hemangiorwa and vascular malformation about 1.0 cm x (0. 5-5.0) cm x 10.0 cm in size, underwent 1% lauromacrogol intratumor injection therapy. Generally, the injection dose, concentration, frequency were determined by the age of the patients, the volume and depth of the lesion. The dose was limited to 10 mg every time. The injection interval is 14 weeks. After followed up for 3-16 months, 41 cases were cured, 9 cases were greatly improved, and 5 were partially improved. Skin necrosis happened in only 2 cases. Lauromacrogol is safe, simple and effective as a sderosing agent for the treatment of facial refractory hemangioma and vascular malformation. It provides a new and alternative way for the treatment of facial refractory hemangioma and vascular malformation.

We report a case in a two and a half month old boy presenting a mass in the right parotid gland. Sonography showed a vascular tumor. Magnetic resonance imaging showed an expansive process of the parotid gland measuring 61 x 39 mm taking the contrast with hypo signal in T1 and hyper signal in T2-weighted images. The parotid was extirpated with preservation of the facial nerve. Microscopically the diagnosis of cellular hemangioma associated with CMV infection was made. Hemangiomas of the parotid gland is frequent; the most common tumor in children; the association of juvenile hemangioma of the parotid gland and cytomegalovirus (CMV) is extremely rare: a single case was reported in the literature. The pathologic significance of this association is still discussed, although several experimental studies suggested a relationship between the infection by the cytomegalovirus and this tumor. Our objective is to describe the anatomo-clinical aspects of this lesion and to elucidate the pathologic significance of this association.

The progression of fractured vertebral collapse is not rare after a conservative treatment of vertebral compression fracture (VCF). Teriparatide has been shown to directly stimulate bone formation and improve bone density, but there is a lack of evidence regarding its use in fracture management. Conservative treatment with short-term teriparatide is effective for decreasing the progression of fractured vertebral body collapse. Few studies have reported on the prevention of collapsed vertebral body progression after osteoporotic VCF. Teriparatide rapidly enhances bone formation and increases bone strength. This study evaluated preventive effects of short-term teriparatide on the progression of vertebral body collapse after osteoporotic VCF. Radiographs of 68 women with single-level osteoporotic VCF at thoracolumbar junction (T11-L2) were reviewed. Among them, 32 patients were treated conservatively with teriparatide (minimum 3 months) (group I), and 36 were treated with antiresorptive (group II). We measured kyphosis and wedge angle of the fractured vertebral body, and ratios of anterior, middle, and posterior heights of the collapsed body to posterior height of a normal upper vertebra were determined. The degree of collapse progression was compared between two groups. The progression of fractured vertebral body collapse was shown in both groups, but the degree of progression was significantly lower in group I than in group II. At the last follow-up, mean increments of kyphosis and wedge angle were significantly lower in group I (4.0° ± 4.2° and 3.6° ± 3.6°) than in group II (6.8° ± 4.1° and 5.8° ± 3.5°) (p = 0.032 and p = 0.037). Decrement percentages of anterior and middle border height were significantly lower in group I (9.6 ± 10.3 and 7.4 ± 7.5 %) than in group II (18.1 ± 9.7 and 13.8 ± 12.2 %) (p = 0.001 and p = 0.025), but not in posterior height (p = 0.086). In female patients with single-level osteoporotic VCF at the thoracolumbar junction, short-term teriparatide treatment did not prevent but did decrease the progression of fractured vertebral body collapse.
Vertebral fracture after aircraft ejection during Operation Desert Storm.
Osborne, R G; Cook, A A
1997-04-01
During Operation Desert Storm, 21 United States and 2 Italian military personnel were held in Iraq as prisoners of war. Of these, 18 had ejected from fixed-wing, ejection seat-equipped, combat aircraft prior to their capture. Of the 18, 6 (33%) had sustained vertebral fractures; 4 of these were compression fractures. This fracture rate is comparable to that of previously studied groups. Fractures were noted to be at several different vertebral sites and after ejecting from a variety of aircraft. Apart from contusions and abrasions, vertebral fractures were the most common injuries discovered in this repatriated population. None of the vertebral fractures produced recognizable neurological disability. The development of vertebral fractures was neither associated with the use of any particular ejection system or aircraft nor did the development of vertebral fractures appear dependent on the age, height or length of service of the affected personnel. Ejected aircrew with low altitude mission profiles seemed more predisposed to vertebral fracture than those at high altitudes, but with a small sample population, this relationship was not statistically significant (p > 0.25). Reliable data were unavailable on aircrew positioning and preparation time for ejection.

The authors report Kasabach-Merritt syndrome (KMS) in a patient with thrombocytopenia and splenic hemangioma. A 13-month-old boy with a history of anemia, thrombocytopenia, and abdominal mass was admitted to the hospital. The scintigraphic studies showed that a large mass contiguous to the spleen was responsible for the platelet uptake. After partial splenectomy, the platelet count returned to normal. This report of KMS in a child with splenic hemangioma suggests that the scintigraphic studies are mandatory to confirm diagnosis. Indium-111-labeled platelets are useful in identifying hemangiomatous sequestration of platelets in patients with thrombocytopenia.
Epithelioid hemangioma of the spine: Two cases.
O'Shea, Bendan M; Kim, Jinsuh
2014-01-01
We report two cases of epithelioid hemangioma (EH) manifested in the thoracic spine with associated clinical, radiographic, and pathological findings. Epithelioid hemangioma is a benign vascular tumor that can involve any bone (including the spine in a subset of patients). Although recognized as a benign tumor by the WHO, it can display locally aggressive features. Within the spine, these features may lead to pain, instability, and/or neurologic dysfunction. The radiographic appearance is most typically that of a lytic, well-defined lesion on plain film or CT. The MRI appearance is typically hypointense on T1WI, hyperintense on T2WI, and avidly enhancing, often with an extraosseous soft-tissue component.

Purpose Vertebroplasty is an effective treatment for painful compression fractures refractory to conservative management. Since there are limited data regarding the survival characteristics of this patient population, we compared the survival of a treated to an untreated vertebral fracture cohort to determine if vertebroplasty affects mortality rates. Materials and Methods The survival of a treated cohort, comprising 524 vertebroplasty recipients with refractory osteoporotic vertebral compression fractures, was compared to a separate, historical cohort of 589 subjects with fractures not treated by vertebroplasty who were identified from the Rochester Epidemiology Project. Mortality was compared between cohorts using Cox proportional hazard models adjusting for age, gender, and Charlson indices of co-morbidity. Mortality was also correlated with pre-, peri-, and post-procedural clinical metrics (e.g., cement volume utilization, Roland-Morris Disability Questionnaire score, analog pain scales, frequency of narcotic use, and improvements in mobility) within the treated cohort. Results Vertebroplasty recipients demonstrated 77% of the survival expected for individuals of similar age, ethnicity, and gender within the US population. When compared to individuals with both symptomatic and asymptomatic untreated vertebral fractures, vertebroplasty recipients retained a 17% greater mortality risk. However, when compared to symptomatic untreated vertebral fractures, vertebroplasty recipients had no increased mortality following adjustment for differences in age, sex and co-morbidity (HR 1.02; CI 0.82–1.25). In addition, no clinical metrics used to assess the efficacy of vertebroplasty were predictive of survival. Conclusion Vertebroplasty recipients have mortality rates similar to individuals with untreated symptomatic fractures but worse mortality compared to those with asymptomatic vertebral fractures.

Retinopathy of prematurity (ROP) and infantile hemangiomas are vascular disorders that may share common mechanisms. This study examined a potential clinical association between these disorders in populations of preterm infants at two hospitals in the U.S. and Hungary. Clinically collected data from infants with gestational ages less than 32 weeks born between May 1, 2007 and December 31, 2010 seen in the University of Iowa Children’s Hospital or the Department of Obstetrics and Gynecology, University of Pécs, were abstracted from electronic medical records and entered into a study database. Demographic and clinical variables were examined as potential covariates to the disorders of interest. Data were initially analyzed by center and then combined through meta-analysis. Six hundred eighty-four subjects were studied, 236 from Pécs and 448 from Iowa. There were no significant demographic differences between populations. Univariate analysis on each study population yielded covariates to ROP in each population, including infantile hemangioma, which were entered into a logistic regression model. These models were combined through random effects meta-analysis and demonstrated a significant relationship between infantile hemangioma and ROP (odds ratio=1.84, 95% confidence interval 1.08–3.12). Conclusion Infantile hemangioma and ROP co-occur in premature infant populations. Further studies are needed to investigate the pathogenesis of both disorders. PMID:23408311

To determine drug dose and usage of timolol maleate eye drops in the treatment of superficial infantile hemangioma. Methods: A total of 250 superficial hemangioma infants were recruited and assigned into 5 groups (n=50 for each group): an external application group and 4 exterior coating groups (2, 4, 6, 8 times per day). We evaluated the therapeutic effect of different methods for drug application (external application or exterior coating) and the frequency for drug administration on superficial infantile hemangioma. Results: The external application group (twice a day and 0.5 hour per time) showed better effect than that in the exterior coating group with twice a day (P<0.001). The difference in therapeutic effect between the exterior coating group with 6 times a day and exterior coating group with twice a day or with 3 times a day was significant (P<0.001). The differences in drug efficacy were not found among the exterior coating group with 6 times a day, the exterior coating group with 8 times a day, or the external application group with twice a day (All P>0.05). Conclusion: Drug dose may affect the therapeutic effect of timolol maleate eye drops in superficial hemangioma infants, and exterior coating with 6 times a day may achieve the best curative effect.

Hemangioma is a mesenchymal benign tumor formed by blood vessels. Anomalies affect up to 10% of children and they are more common in females than in males. The aim of our study was to compare the treatment efficacy, namely the curative effect and adverse events, such as loss of pigment and appearance of scarring, between classical surgery techniques and laser techniques. For that reason a group of 223 patients with hemangioma was retrospectively reviewed. For treatment, a pulsed dye laser (PDL) (Rhodamine G, wavelength 595 nm, pulsewidth between 0.45 and 40 ms, spot diameter 7 mm, energy density 9-11 J cm-2) was used and the results were compared with a control group treated with classical surgical therapy under general anesthesia. The curative effects, mainly number of sessions, appearance of scars, loss of pigment, and relapses were evaluated as a marker of successful treatment. From the results it was evident that the therapeutic effects of both systems are similar. The PDL was successful in all cases. The surgery patients had four relapses. Classical surgery is directly connected with the presence of scars, but the system is safe for larger hemangiomas. It was confirmed that the PDL had the optimal curative effect without scars for small lesions (approximately 10 mm). Surgical treatment under general anesthesia is better for large hemangiomas; the disadvantage is the presence of scars.
Percutaneous balloon kyphoplasty for the treatment of vertebral compression fractures
2014-01-01
Background Vertebral compression fractures (VCFs) constitute a major health care problem, not only because of their high incidence but also because of their direct and indirect negative impacts on both patients’ health-related quality of life and costs to the health care system. Two minimally invasive surgical approaches were developed for the management of symptomatic VCFs: balloon kyphoplasty and vertebroplasty. The purpose of this study was to evaluate the effectiveness and safety of balloon kyphoplasty in the treatment of symptomatic VCFs. Methods Between July 2011 and June 2012, one hundred and eighty-seven patients with two hundred and fifty-one vertebras received balloon kyphoplasty in our hospital. There were sixty-five male and one hundred and twenty-two female patients with an average age of 74.5 (range, 61 to 95 years). The pain symptoms and quality of life, were measured before operation and at one day, three months, six months and one year following kyphoplasty. Radiographic data including restoration of kyphotic angle, anterior vertebral height, and any leakage of cement were defined. Results The mean visual analog pain scale decreased from a preoperative value of 7.7 to 2.2 at one day (p < .05) following operation and the Oswestry Disability Index improved from 56.8 to 18.3 (p < .05). The kyphotic angle improved from a mean of 14.4° before surgery to 6.7° at one day after surgery (p < .05). The mean anterior vertebral height increased significantly from 52% before surgery to 74.5% at one day after surgery (p < .05) and 70.2% at one year follow-up. Minor cement extravasations were observed in twenty-nine out of two hundred and fifty-one procedures, including six leakage via basivertebral vein, three leakage via segmental vein and twenty leakage through a cortical defect. None of the leakages were associated with any clinical consequences. Conclusions Balloon kyphoplasty not only rapidly reduced pain and disability but also restored sagittal alignment in our patients at one-year follow-up. The treatment of osteoporotic vertebral compression fractures with balloon kyphoplasty is a safe, effective, and minimally invasive procedure that provides satisfactory clinical results.

The hero shrew's (Scutisorex somereni) massive interlocking lumbar vertebrae represent the most extreme modification of the vertebral column known in mammals. No intermediate form of this remarkable morphology is known, nor is there any convincing theory to explain its functional significance. We document a new species in the heretofore monotypic genus Scutisorex; the new species possesses cranial and vertebral features representing intermediate character states between S. somereni and other shrews. Phylogenetic analyses of DNA sequences support a sister relationship between the new species and S. somereni. While the function of the unusual spine in Scutisorex is unknown, it gives these small animals incredible vertebral strength. Based on field observations, we hypothesize that the unique vertebral column is an adaptation allowing these shrews to lever heavy or compressive objects to access concentrated food resources inaccessible to other animals.

A painless, bluish, submucosal swelling on one side of the floor of the mouth usually indicates the presence of a ranula. Rarely, such a swelling may be caused by an inflammatory disease process in a salivary gland, a neoplasm in the sublingual salivary gland, a lymphatic nodular swelling, or embryologic cysts. We report a patient with swelling in the floor of her mouth that was clinically diagnosed as a ranula. Suspicion arose during surgery that it was a vascular tumor and, on histologic testing, the swelling was confirmed to be a hemangioma. To our knowledge, this is the first report in the literature of a hemangioma presenting as a ranula.

Osteosarcoma was diagnosed in a 7-month-old female German Shepherd Dog with hind limb paresis. Radiography revealed a circumscribed calcified mass in the dorsal vertebral lamina at T13-L1 resulting in extradural compression of the spinal cord. Surgical excision of the mass resulted in gradual return to normal neurologic function. Four weeks after surgery, the dog became severely atactic after rolling onto its back. A chip fracture of T13 was identified, and the dog was euthanatized at the owners' request.

A 43-year-old man presented with sporadic, sudden, brief, and involuntary jerks of his left limbs and trunk muscles. The electromyographic recordings showed short-lasting highly synchronized bursts, compatible with myoclonus limited to the left hemibody. Blink reflex, masseter silent period, cortical and spinal magnetic stimulation, somatosensory cortical evoked potentials, and electroencephalogram (EEG) were normal; the EEG back-averaging showed no spikes preceding the myoclonus. Magnetic resonance imaging and magnetic resonance angiography showed the presence of an anomalous nonectasic right vertebral artery compressing the right side of ventral medulla oblongata. We hypothesize that the aberrant right vertebral artery induced abnormal activation of descending motor tracts responsible for the myoclonus. (c) 2004 Movement Disorder Society.

The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from vertebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating vertebral compression fractures. Nevertheless, the practice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experience and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many questions still remain unanswered.

The vertebral pedicle injuries are clinically common. However, the isolated vertebral pedicle fracture with intact vertebral bodies is a rare lesion. We reported a case of a 66-year-old man who experienced a pedicle fracture after a back massage. The patient sustained osteoporosis, long-existing low back pain and nerve compression symptoms without antecedent major trauma. Imaging findings demonstrated an isolated unilateral L5 vertebral pedicle fracture with intact vertebral bodies, spinal canal stenosis at the L4-5 levels, bulging annulus fibrosus at the L4-S1 levels, bilateral spondylolysis and an L5/S1 spondylolisthesis. The patient underwent L4-S1 decompressive laminectomy, L5/S1 discectomy and neurolysis, and reduction and fixation of the L5 vertebral pedicle fracture and L5/S1 spondylolisthesis using the pedicle nail system. At follow-ups, the patient showed good recovery without pain or numbness in the low back and bilateral lower extremities. This study raises the awareness of a complication of alternative medicine and the possibility of a pedicle fracture caused by a low-energy trauma.

A case is presented of a 31-year-old white man who developed a hemangiosarcoma in the very place where 30 years ago a hemangioma had been treated by radiotherapy. The rarity of such an occurrence is attested to by the fact that only two similar cases were found in the English medical literature.

Identification of patient at risk of subglottic infantile hemangioma (IH) is challenging because subglottic IH can grow fast and cause airway obstruction with a fatal course. To refine the cutaneous IH pattern at risk of subglottic IH. Prospective and retrospective review of patients with cutaneous IH involving the beard area. IHs were classified in the bilateral pattern group (BH) or in the unilateral pattern group (UH). Infantile hemangioma topography, subtype (telangiectatic or tuberous), ear, nose and throat (ENT) manifestations and subglottic involvement were recorded. Thirty-one patients (21 BH and 10 UH) were included during a 20-year span. Nineteen patients (16 BH and 3 UH) had subglottic hemangioma. BH and UH group overlap on the median pattern (tongue, gum, lips, chin and neck). Median pattern, particularly the neck area and telangiectatic subtype of IH were significantly associated with subglottic involvement. Patients presenting with telangiectatic beard IH localized on the median area need early ENT exploration. They should be treated before respiratory symptoms occur. © 2016 European Academy of Dermatology and Venereology.

Infantile hemangioma (IH) is a vascular tumor that begins with rapid vascular proliferation shortly after birth, followed by vascular involution in early childhood. We have found that NOTCH3, a critical regulator of mural cell differentiation and maturation, is expressed in hemangioma stem cells (HemSCs), suggesting that NOTCH3 may function in HemSC-to-mural cell differentiation and pathological vessel stabilization. Here, we demonstrate that NOTCH3 is expressed in NG2+PDGFRβ+ perivascular HemSCs and CD31+GLUT1+ hemangioma endothelial cells (HemECs) in proliferating IHs and becomes mostly restricted to the αSMA+NG2loPDGFRβlo mural cells in involuting IHs. NOTCH3 knockdown in HemSCs inhibited in vitro mural cell differentiation and perturbed αSMA expression. In a mouse model of IH, NOTCH3 knockdown or systemic expression of the NOTCH3 inhibitor, NOTCH3 Decoy, significantly decreased IH blood flow, vessel caliber, and αSMA+ perivascular cell coverage. Thus, NOTCH3 is necessary for HemSC-to-mural cell differentiation, and adequate perivascular cell coverage of IH vessels is required for IH vessel stability.

Urethral hemangiomas are rare. They vary in size from pinpoint masses to extensive honeycomb-shape deformities leading to significant hematuria. For extensive lesions, therapeutic options have included extensive surgical resection and reconstruction or multistaged neodymium:yttrium-aluminum-garnet (Nd:YAG) laser photocoagulation. We report our experience with the use of potassium titanyl phosphate (KTP/532) laser for treatment of the extensive form. A 7-year-old boy presented with a 2-week history of urethral bleeding. He had extensive hemangiomas of the genital and perineal regions. Cystourethroscopy disclosed diffusely scattered honeycomb-shape hemangiomatous malformation of the anterior urethra. KTP/532 laser energy was delivered transurethrally to the hemangiomatous areas until they blanched. The Foley catheter was removed 24 hours postoperatively, and the patient voided clear urine without difficulty. He has remained trouble-free for more than 2 years. Judicious endoscopic single-stage therapy with KTP/532 laser may obviate open surgical intervention in most cases of extensive and symptomatic urethral hemangiomas. In view of our observation and the literature, KTP/532 laser therapy should be considered the first line of treatment.

The clinical features, radiologic investigation, and treatment of 20 infants with hepatic hemangiomas are presented. Palpable abdominal mass (n = 18) and cardiac failure (n = 11) were the common presenting features. Nine patients had hyperconsumptive coagulopathy. Seven patients had other hemangiomas. Ultrasound (n = 15) showed the number and distribution of the hemangiomas within the liver. Hypoechoic and hyperechoic elements were present in addition to prominent vascular channels and diminished caliber of the distal aorta. Radionuclide sulfur colloid (n = 12) and labeled red blood cell (n = 7) studies showed the distribution and vascularity of the hemangiomas. Computedmore » tomography (n = 8) revealed central hypointensity with marked peripheral enhancement after contrast. Arteriography now performed only as a prelude to therapeutic embolization demonstrated hypervascularity in each patient, contrast pooling in six and early draining veins in five. Magnetic resonance scanning (n = 3) showed decreased signal intensity on T1 images and high intensity signal on T2. In two patients, there was resolution or improvement of the hemangiomas without therapy. Four patients had surgery (lobectomy (2), trisegmentectomy (1), and surgical evacuation of a central hematoma (1)). Steroids and radiation were given to seven patients, and one patient also required therapeutic embolization. Steroids were the initial therapy in five patients, one of whom later required therapeutic embolization and another cyclophosphamide. Two patients were treated initially with radiation therapy, one of whom also needed emergency hepatic artery ligation. Seventeen of the 20 patients are alive and well from 6 months to 14 years after diagnosis.« less

To investigate the clinical efficiency of electrocoagulation for the treatment of noninvoluting congenital hemangioma. Sixteen infants with noninvoluting congenital hemangioma who were admitted to our hospital from January 2011 to June 2013 were included in this study. Color Doppler ultrasound was used to determine the hemangioma location, as well as its size and depth. High frequency electrocoagulation was adopted for the treatment. The output power was set at 10-20 W. The probes were inserted around the tumor or at the surface of the tumor. After switching on for 1-2 seconds, the direction and position of the probe was modulated until covering the whole tumor. After the treatment, the absorption of tumor was about 3-6 months. The efficiency was evaluated during the follow-up. Tumor atrophy was obvious after treatment in all patients. The temperature around the tumor mass was decreased, and the aberrant blood signals were decreased under the ultrasonic examination. Complete or partial atrophy were observed. The efficiency was graded as level I, II, III, IV in 0, 2, 9 and 5 patients, respectively. One patient showed local infection due to improper nursing, which was completely relieved after corresponding treatment. No severe adverse events were observed. High-frequency electrocoagulation is effective for treating noninvoluting congenital hemangioma through coagulating the aberrant blood vessels in the tumor, interrupting the vascular endothelial cell, blocking the aberrant blood flow, as well as leading to atrophy and absorption of tumor mass. Besides, no obvious scar is observed after the surgery.

To evaluate technetium Tc 99m (99mTc) red blood cell scintigraphy as a diagnostic tool for orbital cavernous hemangioma and to differentiate between orbital masses on the basis of their vascularization. We performed 99mTc red blood cell scintigraphy on 23 patients (8 female and 15 male; mean age, 47 years) affected by an orbital mass previously revealed with computed tomography (CT) and magnetic resonance imaging (MRI) and suggesting cavernous hemangioma. In our diagnosis, we considered the orbital increase delayed uptake with the typical scintigraphic pattern known as perfusion blood pool mismatch. The patients underwent biopsy or surgical treatment with transconjunctival cryosurgical extraction when possible. Single-photon emission tomography (SPET) showed intense focal uptake in the orbit corresponding to radiologic findings in 11 patients who underwent surgical treatment and pathologic evaluation (9 cavernous hemangiomas, 1 hemangiopericytoma, and 1 lymphangioma). Clinical or histologic examination of the remaining 22 patients revealed the presence of 5 lymphoid pseudotumors, 2 lymphomas, 2 pleomorphic adenomas of the lacrimal gland, 1 astrocytoma, 1 ophthalmic vein thrombosis, and 1 orbital varix. The confirmation of the preoperative diagnosis by 99mTc red blood cell scintigraphy shows that this technique is a reliable tool for differentiating cavernous hemangiomas from other orbital masses (sensitivity, 100%; specificity, 86%) when ultrasound, CT, and MRI are not diagnostic. Unfortunately, 99mTc red blood cell scintigraphy results were positive in 1 patient with hemangiopericytoma and 1 patient with lymphangioma, which showed increased uptake in the lesion on SPET images because of the vascular nature of these tumors. Therefore, in these cases, the SPET images have to be integrated with data regarding clinical preoperative evaluation and CT scans or MRI studies. On the basis of our study, a complete diagnostic picture, CT scans or MRI studies, and scintigraphic patterns can establish the preoperative diagnosis of vascular orbital tumors such as cavernous hemangioma, adult-type lymphangioma, and hemangiopericytoma.

Synovial hemangioma is a rare condition with <200 published case reports in world literature and is frequently misdiagnosed, leading to diagnostic delay of many years. This delay is even more significant if the patient comes from a rural background with a dearth of medical facilities in the area. This case had a lag of nearly 20 years from the time of onset of symptoms and the required management which is the maximum reported for any synovial hemangioma since most of them have been found and treated in adolescents. We present a case of an atypical synovial hemangioma in a 25-year-old Indian male from a poor socioeconomic background with a delay of 20 years who had both recurrent knee effusions and long-standing knee pain but kept ignoring his symptoms. It was managed by arthroscopic synovectomy. The patient reported to us after 2 years after the surgery with a painless knee and full range of movement. Synovial hemangioma mostly affects the knee joint, showing recurrent bloody effusions without a history of trauma. If there are no intermittent effusions, the diagnosis will be even more difficult. In cases of non-specific symptoms and long-standing knee pain of many years, the diagnosis of a synovial hemangioma should also be considered. In this particular case, magnetic resonance imaging was used to evaluate the patient after the plain radiographs and showed characteristic lace-like or linear patterns. Diagnostic arthroscopy and surgical excision were done in the same sitting, and biopsy was sent to the histopathology laboratory which confirmed our diagnosis. Although this patient had the disease since 20 years and presented late, he had little degeneration of cartilage at the time of arthroscopy. The functional outcome at 2-year follow-up was excellent, and he had no disability, effusion and was pain free.

Purpose: The aim of this study was to compare, on a retrospective basis, the results of therapy in patients with uveal hemangioma treated with photon or proton irradiation at a single center. Methods and Materials: From 1993 to 2002 a total of 44 patients were treated. Until 1998 radiotherapy was given with 6 MV photons in standard fractionation of 2.0 Gy 5 times per week. In 1998 proton therapy became available and was used since then. A dose of 20 to 22.5 Cobalt Gray Equivalent (CGE) 68 MeV protons was given on 4 consecutive days. Progressive symptoms or deterioration ofmore » vision were the indications for therapy. Results: Of the 44 patients treated, 36 had circumscribed choroidal hemangiomas and 8 had diffuse choroidal hemangiomas (DCH) and Sturge-Weber syndrome. Of the patients, 19 were treated with photons with a total dose in the range of 16 to 30 Gy. A total of 25 patients were irradiated with protons. All patients with DCH but 1 were treated with photons. Stabilization of visual acuity was achieved in 93.2% of all patients. Tumor thickness decreased in 95.4% and retinal detachment resolved in 92.9%. Late effects, although generally mild or moderate, were frequently detected. In all, 40.9% showed radiation-induced optic neuropathy, maximum Grade I. Retinopathy was found in 29.5% of cases, but only 1 patient experienced more than Grade II severity. Retinopathy and radiation-induced optic neuropathy were reversible in some of the patients and in some resolved completely. No differences could be detected between patients with circumscribed choroidal hemangiomas treated with protons and photons. Treatment was less effective in DCH patients (75%). Conclusions: Radiotherapy is effective in treating choroidal hemangiomas with respect to visual acuity and tumor thickness but a benefit of proton therapy could not be detected. Side effects are moderate but careful monitoring for side effects should be part of the follow-up procedures.« less

The effects of corticosteroid on bone were examined in female growing rabbits treated with 0.7 mg/kg per day prednisolone for 5 months. The evolution of whole-body total bone mineral measured by dual-photon absorptiometry showed a significant difference between the prednisolone-treated group and the control group from the first to the fifth month. The histomorphometric profile of corticosteroid-induced osteoporosis was observed, in particular the lower bone volume and thinner and fewer trabecular plates. Mechanical tests are possible on rabbit vertebrae and showed a very significant difference in bone strength between the prednisolone-treated and control groups, and a good correlation between mechanical tests and histomorphometric or densitometric results. This bone corticosteroid model shows that vertebral compression tests are possible on rabbit lumbar vertebrae. It may contribute to a better evaluation of corticosteroid treatments.

In 2002, approximately 38,000 vertebroplasties and 16,000 kyphoplasties were performed in the United States. As the use of both modalities for the treatment of vertebral compression fractures has increased, so have questions regarding safety and efficacy. The authors addressed this by reviewing both the current literature and complications data reported to the Food and Drug Administration (FDA) Center for Devices and Radiological Health through the on-line database (http://www.fda.gov/cdrh/maude.html) and through the Office of the Freedom of Information Act at the FDA. Although both procedures are largely safe, the FDA data highlight two main concerns: reactions to the use of acrylic (polymethylmethacrylate) bone cement, including hypotension and, in some cases, death, especially when multiple vertebral levels are treated in one setting; and a possible increased risk with kyphoplasty of pedicle fracture and cord compression.

Percutaenous Vertebroplasty (PVP) is effective in alleviating pain and facilitating early mobilization following vertebral compression fractures. The relatively high risk of extravertebral leakage due to uncontrolled delivery of low viscosity bone cement is an inherent limitation of the technique. The aim of this research is to investigate the ability of controlled cement delivery in decreasing the rate of such complications by applying radiofrequency heating to regulate cement viscosity. Thirty two vetebrae were treated in 28 patients as part of an Ethics Committee approved multicenter clinical trial using RadioFreqency assisted Percutaenous Vertebral Augmentation (RF-PVA) technique. This technique is injecting low viscosity polymethylmethacrylate (PMMA) bone cement using a pressure controlled hydraulic pump and applying radiofrequency heating to increase cement viscosity prior to entering the vertebral body. All patients were screened for any cement leakage by X-ray and CT scan. The intensity of pain was recorded on a Visual Analog Scale (VAS) and the level of physical activity on the Oswestry Disability Index (ODI) prior to, one day, one month and three months following procedure. All procedures were technically successful. There were no clinical complication, intraspinal or intraforaminal cement leakage. In nine cases (29%) a small amount of PMMA entered the intervertebral space through the broken end plate. Intensity of pain by VAS was reduced from a mean of 7.0 to 2.5 and physical inactivity dropped on the ODI from 52% to 23% three months following treatment. In this small series controlled cement injection using RF-PVA was capable of preventing clinically hazardous extravertebral cement leakage while achieving outcomes similar to that of conventional vertebroplasty.

To compare the stiffness, angular deformation, and mode of failure of lumbar vertebral column constructs stabilized with bilateral pins and polymethylmethacrylate (Pin-PMMA) or with a unilateral (left) locking compression plate (LCP) with monocortical screws. Ex vivo biomechanical, non-randomized. Cadaveric canine thoracolumbar specimens (n=16). Thoracolumbar (T13-L3) vertebral specimens had the L1-L2 vertebral motion unit stabilized with either Pin-PMMA or LCP. Stiffness in flexion, extension, and right and left lateral bending after nondestructive testing were compared between intact (pretreated) specimens and Pin-PMMA, and LCP constructs. The Pin-PMMA and LCP constructs were then tested to failure in flexion and left lateral bending. Both the Pin-PMMA and LCP constructs had reduced range of motion at the stabilized L1-L2 vertebral motion unit compared to intact specimens. The Pin-PMMA constructs had less range of motion for the flexion elastic zone than LCP constructs. The Pin-PMMA constructs were stiffer than intact specimens in flexion, extension, and lateral bending, and stiffer than LCP constructs in flexion and left lateral bending. The Pin-PMMA constructs had less angular deformation at construct yield and lower residual deformation at L1-L2 than LCP constructs after destructive testing to failure in flexion. The Pin-PMMA constructs were stiffer, stronger, and had less deformation at yield than LCP constructs after destructive testing to failure in lateral bending. Most constructs failed distant to the implant and fixation site. Pin-PMMA constructs had greater lumbar vertebral stiffness and reduced ROM than LCP constructs; however, both Pin-PMMA and LCP constructs were stronger than intact specimens. © Copyright 2016 by The American College of Veterinary Surgeons.

The long-term protective effect of stronger back muscles on the spine was determined in 50 healthy white postmenopausal women, aged 58-75 years, 8 years after they had completed a 2 year randomized, controlled trial. Twenty-seven subjects had performed progressive, resistive back-strengthening exercises for 2 years and 23 had served as controls. Bone mineral density, spine radiographs, back extensor strength, biochemical marker values, and level of physical activity were obtained for all subjects at baseline, 2 years, and 10 years. Mean back extensor strength (BES) in the back-exercise (BE) group was 39.4 kg at baseline, 66.8 kg at 2 years (after 2 years of prescribed exercises), and 32.9 kg at 10 years (8 years after cessation of the prescribed exercises). Mean BES in the control (C) group was 36.9 kg at baseline, 49.0 kg at 2 years, and 26.9 kg at 10 years. The difference between the two groups was still statistically significant at 10 year follow-up (p = 0.001). The difference in bone mineral density, which was not significant between the two groups at baseline and 2 year follow-up, was significant at 10 year follow-up (p = 0.0004). The incidence of vertebral compression fracture was 14 fractures in 322 vertebral bodies examined (4.3%) in the C group and 6 fractures in 378 vertebral bodies examined (1.6%) in the BE group (chi-square test, p = 0.0290). The relative risk for compression fracture was 2.7 times greater in the C group than in the BE group. To our knowledge, this is the first study reported in the literature demonstrating the long-term effect of strong back muscles on the reduction of vertebral fractures in estrogen-deficient women.

Atlantic salmon (Salmo salar L.) vertebral bone displays plasticity in structure, osteoid secretion and mineralization in response to photoperiod. Other properties of the vertebral bone, such as mineral content and mechanical strength, are also associated with common malformations in farmed Atlantic salmon. The biological mechanisms that underlie these changes in bone physiology are unknown, and in order to elucidate which factors might be involved in this process, microarray assays were performed on vertebral bone of Atlantic salmon reared under natural or continuous light. Eight genes were upregulated in response to continuous light treatment, whereas only one of them was upregulated in a duplicate experiment. The transcriptionally regulated gene was predicted to code for collagen type XI alpha1, a protein known to be involved in controlling the diameter of fibrillar collagens in mammals. Furthermore, the gene was highly expressed in the vertebrae, where spatial expression was found in trabecular and compact bone osteoblasts and in the chordoblasts of the notochordal sheath. When we measured the expression level of the gene in the tissue compartments of the vertebrae, the collagen turned out to be 150 and 25 times more highly expressed in the notochord and compact bone respectively, relative to the expression in the trabecular bone. Gene expression was induced in response to continuous light, and reduced in compressed vertebrae. The downregulation in compressed vertebrae was due to reduced expression in the compact bone, while expression in the trabecular bone and the notochord was unaffected. These data support the hypothesis that this gene codes for a presumptive collagen type XI alpha1, which may be involved in the regulatory pathway leading to structural adaptation of the vertebral architecture.
Quantitative computed tomography-based predictions of vertebral strength in anterior bending.

This study examined the ability of QCT-based structural assessment techniques to predict vertebral strength in anterior bending. The purpose of this study was to compare the abilities of QCT-based bone mineral density (BMD), mechanics of solids models (MOS), e.g., bending rigidity, and finite element analyses (FE) to predict the strength of isolated vertebral bodies under anterior bending boundary conditions. Although the relative performance of QCT-based structural measures is well established for uniform compression, the ability of these techniques to predict vertebral strength under nonuniform loading conditions has not yet been established. Thirty human thoracic vertebrae from 30 donors (T9-T10, 20 female, 10 male; 87 +/- 5 years of age) were QCT scanned and destructively tested in anterior bending using an industrial robot arm. The QCT scans were processed to generate specimen-specific FE models as well as trabecular bone mineral density (tBMD), integral bone mineral density (iBMD), and MOS measures, such as axial and bending rigidities. Vertebral strength in anterior bending was poorly to moderately predicted by QCT-based BMD and MOS measures (R2 = 0.14-0.22). QCT-based FE models were better strength predictors (R2 = 0.34-0.40); however, their predictive performance was not statistically different from MOS bending rigidity (P > 0.05). Our results suggest that the poor clinical performance of noninvasive structural measures may be due to their inability to predict vertebral strength under bending loads. While their performance was not statistically better than MOS bending rigidities, QCT-based FE models were moderate predictors of both compressive and bending loads at failure, suggesting that this technique has the potential for strength prediction under nonuniform loads. The current FE modeling strategy is insufficient, however, and significant modifications must be made to better mimic whole bone elastic and inelastic material behavior.

A biomechanical study using human cadaveric thoracolumbar spinal columns. To compare the effect of treatment by vertebroplasty (VP) with polymethylmethacrylate cement and VP with calcium phosphate cement on the creation of adjacent vertebral body fracture following VP. Adjacent vertebral body fractures have been reported as a complication following VP. Twenty-four spinal columns (T10-L2) from human cadavers were subjected to dual energy radiograph absorptiometry to assess bone mineral density. They were divided into the P group and C group, and experimental vertebral compression fractures were created at T12 vertebrae. T12 vertebrae were augmented with polymethylmethacrylate and calcium phosphate cement in the P group and C group, respectively. Each spinal column was compressed until a new fracture occurred at any vertebra, and the location of newly fractured vertebra and failure load was investigated. There was no significant difference in bone mineral density at each level within each group. In the P group, a new fracture occurred at T10 in 2 specimens, T11 in 8, and L1 in 2. In the C group, it occurred at T10 in 1 specimen, T11 in 2, L1 in 1, and T12 (treated vertebra) in 8. The failure loads of the spinal column were 1774.8+/-672.3 N and 1501.2+/-556.5 N in the P group and C group, respectively. There was no significant difference in the failure load of the spinal column between each group. New vertebral fractures occurred at the vertebra adjacent to augmented vertebrae in the P group and in the augmented vertebrae in the C group. The difference in the fractured site may be because of the difference in strength between the 2 bone filler materials. Therefore, the strength of bone filler materials is considered a risk factor in developing adjacent vertebral body fractures after VP.

Hemangioma, a most frequently encountered primary benign tumor of the liver, is generally determined incidentally during the course of radiologic tests for other reasons. Most lesions are less than 3 cm and a significant proportion of patients are asymptomatic, although the size and location of the lesion in some patients may be associated with the onset of symptoms. Pressure on the stomach and duodenum of giant hemagiomas developing in the left lobe of the liver, in particular, may result in the development of abdominal pain, nausea, vomiting, and feeling bloated, which are characteristic of a gastric outlet obstruction. A 42-year-old man presented with findings of gastric outlet obstruction and weight loss as a result of a giant hepatic hemangioma. PMID:23438272
Painful erections secondary to rare epithelioid hemangioma of the penis.
Barber, Evan; Domes, Trustin
2014-09-01
Epithelioid hemangioma is a rare benign vascular tumour that atypically involves the penis and usually presents as a painful nodule. A 35-year-old man presented with a 5-month history of painful erections without a clinically apparent lesion or deformity. Magnetic resonance imaging (MRI) with pharmacologically induced erection demonstrated a 1.3-cm nodular lesion deep to the skin at the base of his penis. Following local excision of the lesion, which was diagnosed as an epithelioid hemangioma, the patient was symptom free. This case demonstrates a rare etiology of painful erections with a unique presentation. To the authors' knowledge, it is also the first report of MRI with intracavernosal injection of trimix to assess for a specific cause of painful erections.

We describe a 6-week-old girl with a right upper lid capillary hemangioma, ipsilateral morning glory disk anomaly, microphthalmos, Mittendorf dot, and Horner syndrome. The ipsilateral internal carotid artery was also found to be absent. To our knowledge, this is the first patient to be reported with this group of findings. We suggest that this represents an overlap between morning glory disk and intracranial vascular abnormalities, a recognized association, and PHACES syndrome (posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye, and sternal abnormalities). We discuss the common embryological basis for these abnormalities, which point to a widespread but highly variable disorder of mesodermal differentiation.

A 38-year-old male Bornean orangutan (Pongo pygmaeus pygmaeus) developed progressive hind leg paresis. A computed tomography scan of the vertebral column revealed soft tissue type densities within vertebral bones. At necropsy infiltrating tumor masses were found in the vertebral bodies, protruding into the spinal canal and compressing the spinal cord. Microscopically neoplastic plasma cells infiltrated the vertebral bodies and adjacent soft tissues. Immunohistochemically, tumor cells tested positive for B cell markers (CD38, CD79alpha), kappa, and lambda light chains, while vimentin, GFAP, S100, and CD138 were not expressed. The tumor was classified as multiple myeloma on the basis of radiographic, pathological, and immunohistochemical findings. This first systematic case description on multiple myeloma in a non-human primate revealed many similarities with the disease in humans and the immunohistochemical tools proved suitable for their use in the orangutan.

To evaluate color Doppler imaging (CDI) as the primary imaging modality in the diagnosis of pediatric orbital capillary hemangioma. This is a retrospective study of 36 consecutive cases of orbital capillary hemangiomas between January 2006 and July 2011. Data on demographic details, clinical findings, gray-scale ultrasonography, CDI characteristics, treatment, and follow-up period were reviewed. The mean age of onset was 7 weeks. Twenty-nine (81%) lesions presented as eyelid masses, whereas seven (19%) presented as exophthalmos. Nineteen (53%) tumors were located on the upper eyelid, seven (19%) on the lower eyelid, six (17%) in the medial canthus, and one on both upper and lower eyelids. Ultrasonography depicted a heterogeneous, well-defined, irregular tumor with a low or moderate echogenicity. All lesions presented with abundant color blood flow on CDI. The intralesional blood flow had a mean peak systolic velocity of 37.5 ± 24.5 cm/second, and a mean resistance index of 0.69 ± 0.16, representing a shift in the pulse Doppler toward high velocity and high resistance. After a single intratumoral injection of betamethasone, 18 cases (50%) resolved. Additionally, 15 (42%) and four (11%) cases resolved after two injections and three injections, respectively. Only three (8%) masses persisted after three injections within the follow-up period. The blood flow characteristics of CDI play a vital role in the differentiation of orbital capillary hemangiomas from other orbital lesions. The availability and lack of adverse effects of CDI enable its utilization in the early clinical diagnosis of pediatric orbital capillary hemangioma. Copyright © 2014. Published by Elsevier B.V.

Posterior reduction and pedicle screw fixation is a widely used procedure for thoracic and lumbar vertebrae fractures. Usually, the pedicle screws would be removed after the fracture healing and screw tunnels would be left. The aim of this study is to evaluate the effect of screw tunnels on the biomechanical stability of the lumbar vertebral body after pedicle screws removal by finite element analysis (FEA). First, the CT values of the screw tunnels wall in the fractured vertebral bodies were measured in patients whose pedicle screws were removed, and they were then compared with the values of vertebral cortical bone. Second, an adult patient was included and the CT images of the lumbar spine were harvested. Three dimensional finite element models of the L1 vertebra with unilateral or bilateral screw tunnels were created based on the CT images. Different compressive loads were vertically acted on the models. The maximum loads which the models sustained and the distribution of the force in the different parts of the models were recorded and compared with each other. The CT values of the tunnels wall and vertebral cortical bone were 387.126±62.342 and 399.204±53.612, which were not statistically different (P=0.149). The models of three dimensional tetrahedral mesh finite element of normal lumbar 1 vertebra were established with good geometric similarity and realistic appearance. After given the compressive loads, the cortical bone was the first one to reach its ultimate stress. The maximum loads which the bilateral screw tunnels model, unilateral screw tunnel model, and normal vertebral model can sustain were 3.97 Mpa, 3.83 Mpa, and 3.78 Mpa, respectively. For the diameter of the screw tunnels, the model with a diameter of 6.5 mm could sustain the largest load. In addition, the stress distributing on the outside of the cortical bone gradually decreased as the thickness of the tunnel wall increased. Based on the FEA, pedicle screw tunnels would not decrease the biomechanical stability and strength of the vertebral body. A large diameter of screw tunnel and thick tunnel wall were helpful for the biomechanical stability of the vertebral body.

Three cases of surface-based hemangiomas were reviewed. The cases illustrate the plain film and magnetic resonance imaging findings of these benign tumors, which can appear quite aggressive, mimicking more aggressive neoplasms. Each of the patients underwent en bloc excision, and pathologic evaluation to determine the diagnosis. To date, there has been no evidence of recurrence.

We describe the clinical, radiological and pathological findings of concurrent, congenital leptomeningeal arteriovenous malformation with hemangioma diagnosed in a newborn by prenatal and immediately postnatal magnetic resonance imaging. Vascular abnormalities were accompanied by massive arachnoidal cell hyperplasia reminiscent of meningioma. To the best of our knowledge, this is the first case of such a lesion reported in the literature.
Removal of an orbital apex hemangioma using an endoscopic transethmoidal approach: technical note.
Karaki, Masayuki; Kobayashi, Ryuichi; Mori, Nozomu
2006-07-01
The posterior orbit contains a number of important and vulnerable structures, including the optic nerve, the ophthalmic artery and vein, and the ocular muscles and their motor nerves, which makes surgical access to the lesion in this region quite difficult. Transfrontal, transfrontal-ethmoidal, and transmaxillary procedures have the disadvantage of possible injuries to a number of nontumor structures, whereas an endoscopic transethmoidal approach is a minimally invasive surgery for the retrobulbar lesions. Retrobulbar cavernous hemangioma was successfully removed by a transethmoidal approach. Tumor removal was performed in a patient with an intraconal cavernous hemangioma of approximately 15 mm in diameter. By a transethmoidal approach, the medial-inferior part of the orbit, as well as the apex of the orbit, were clearly visualized after endonasal ethmoidectomy. After the removal of the medial orbital bone, the orbital periosteum was incised and elevated. By elevating the orbital fat, the tumor could be identified separately from the orbital contents. Cavernous hemangioma at the orbital apex was removed without complications. An endoscopic transethmoidal approach, which requires no skin incision, is a minimally invasive surgery for retrobulbar orbital tumor, leading to excellent cosmetic results with less bleeding.

This paper focuses on the improvement of the diagnostic accuracy of focal liver lesions by quantifying the key features of cysts, hemangiomas, and malignant lesions on ultrasound images. The focal liver lesions were divided into 29 cysts, 37 hemangiomas, and 33 malignancies. A total of 42 hybrid textural features that composed of 5 first order statistics, 18 gray level co-occurrence matrices, 18 Law's, and echogenicity were extracted. A total of 29 key features that were selected by principal component analysis were used as a set of inputs for a feed-forward neural network. For each lesion, the performance of the diagnosis was evaluated by using the positive predictive value, negative predictive value, sensitivity, specificity, and accuracy. The results of the experiment indicate that the proposed method exhibits great performance, a high diagnosis accuracy of over 96% among all focal liver lesion groups (cyst vs. hemangioma, cyst vs. malignant, and hemangioma vs. malignant) on ultrasound images. The accuracy was slightly increased when echogenicity was included in the optimal feature set. These results indicate that it is possible for the proposed method to be applied clinically.
Spinal bone marrow necrosis with vertebral compression fracture: differentiation of BMN from AVN.
Nix, J S; Fitzgerald, R T; Samant, R S; Harrison, M; Angtuaco, E J
2014-09-01
Bone marrow necrosis (BMN) is a rare malignancy-associated hematologic disorder characterized by necrosis of myeloid and stromal marrow elements with preservation of cortical bone. Overlap between the imaging appearances of BMN and avascular necrosis (AVN) raises the potential for diagnostic confusion. We report a case of BMN presenting with a traumatic multi-level vertebral body collapse, and finding that may potentially confound distinction between the two entities. We discuss important pathophysiologic, clinical, and radiologic differences between BMN and AVN with emphasis on features important in the differential diagnosis.

Most cranial nerve compression syndromes (ie, trigeminal neuralgia and hemifacial spasm) are caused by small arteries impinging on a nerve and are relieved by microvascular decompression. Rarely, cranial nerve compression syndromes can be caused by large artery impingement and can be relieved by macrovascular decompression. When present, this compression often occurs in association with degenerative atherosclerosis in the vertebral arteries (VA) and basilar artery. Conservative treatment is recommended for mild forms, but surgical transposition of the VA away from the root entry zone (REZ) can be considered. This video demonstrates macrovascular decompression of a dolichoectatic VA in a 74-yr-old female with refractory left hemifacial spasm. After obtaining IRB approval, patient consent was sought for the procedure. With the patient in three-quarter-prone position, a far-lateral craniotomy was performed. The dentate ligament was cut to free the VA, and the suprahypoglossal portion of the vagoaccessory triangle was widened. VA compressed the REZ of the facial nerve, but was mobilized anteromedially off the REZ. A muslin sling was wrapped around the VA and its tail brought down to the clival dura, which was punctured with a 19-gauge needle and enlarged with a dissector. The sling was pulled anteromedially to this puncture site and secured to the dura with an aneurysm clip, relieving the REZ of all compression. The patient tolerated the procedure with mild, transient hoarseness and her hemifacial spasm resolved completely. This case demonstrates the macrovascular decompression technique with anteromedial transposition of the vertebrobasilar artery, which can also be used for trigeminal neuralgia.

An increasing number of studies have been conducted to apply unilateral balloon kyphoplasty in the treatment of ostroporotic vertebral compression fractures (OVCFs). However, the efficacy and safety of unilateral kyphoplasty and whether a unilateral or a bilateral approach is superior is controversial. The purpose of this study was to evaluate the role of unilateral balloon kyphoplasty and use meta-analysis to compare the efficacy and safety of unilateral and bilateral kyphoplasty in patients with OVCFs. A systematic literature search was conducted from 1970 to April 2017 using Medline database and the Cochrane Central Register of Controlled Trials. Articles were limited to those published in English. Randomized controlled trials and nonrandomized comparative studies were also included. The following search terms were used: "osteoporotic vertebral compression fractures," or "OVCF," and "unilateral kyphoplasty," or "unipedicular approach," or "single balloon kyphoplasty," or "one balloon kyphoplasty." A comprehensive search of reference lists of retrieved articles and previous published reviews was also performed to ensure inclusion of all possible studies. All potential articles were independently reviewed by 2 investigators for inclusion into the final analysis. MINORS score was used for nonrandomized studies, and Detsky quality index was applied for prospective randomized controlled trials. Systematic review and meta-analysis was performed for the included studies. After unilateral balloon kyphoplasty the mean postoperative visual analog score (VAS) was from 1.74 to 4.77, mean postoperative kyphotic angle was from 5.9º to 11.22º, and complications involving cement leaks was from 6.8 to 21.9% or adjacent level fractures was from 0 to 5.6%). Unilateral kyphoplasty had significantly lower operative time, and less bone cement volume; however, the postoperative VAS, Oswestry Disability Index (ODI), vertebral height restoration rate, and cement leakage and adjacent vertebral fracture rate, were similar to bilateral kyphoplasty. Only 6 randomized controlled trials and 3 retrospective comparative studies were selected for analysis. Heterogeneity was detected among the studies when we pooled the outcomes. Based on the available evidence, the clinical and radiological results of unilateral balloon kyphoplasty were as good as those of bilateral balloon kyphoplasty for the treatment of OVCFs. And unilateral kyphoplasty had advantages in terms of operation time, radiation exposure, and cost. Unilateral balloon kyphoplasty, bilateral balloon kyphoplasty, osteoporotic vertebral compression fractures, complications of balloon kyphoplasty, meta-analysis.

Percutaneous vertebroplasty (PVP) and balloon kyphoplasty (BKP) are minimally invasive and effective vertebral augmentation techniques for managing osteoporotic vertebral compression fractures (OVCFs). Recent meta-analyses have compared the incidence of secondary vertebral fractures between patients treated with vertebral augmentation techniques or conservative treatment; however, the inclusions were not thorough and rigorous enough, and the effects of each technique on the incidence of secondary vertebral fractures remain unclear. To perform an updated systematic review and meta-analysis of the studies with more rigorous inclusion criteria on the effects of vertebral augmentation techniques and conservative treatment for OVCF on the incidence of secondary vertebral fractures. PubMed, MEDLINE, EMBASE, SpringerLink, Web of Science, and the Cochrane Library database were searched for relevant original articles comparing the incidence of secondary vertebral fractures between vertebral augmentation techniques and conservative treatment for patients with OVCFs. Randomized controlled trials (RCTs) and prospective non-randomized controlled trials (NRCTs) were identified. The methodological qualities of the studies were evaluated, relevant data were extracted and recorded, and an appropriate meta-analysis was conducted. A total of 13 articles were included. The pooled results from included studies showed no statistically significant differences in the incidence of secondary vertebral fractures between patients treated with vertebral augmentation techniques and conservative treatment. Subgroup analysis comparing different study designs, durations of symptoms, follow-up times, races of patients, and techniques were conducted, and no significant differences in the incidence of secondary fractures were identified (P > 0.05). No obvious publication bias was detected by either Begg's test (P = 0.360 > 0.05) or Egger's test (P = 0.373 > 0.05). Despite current thinking in the field that vertebral augmentation procedures may increase the incidence of secondary fractures, we found no differences in the incidence of secondary fractures between vertebral augmentation techniques and conservative treatment for patients with OVCFs. © The Foundation Acta Radiologica 2014.

Intraosseous hemangiomas in the jaws are rare lesions and may lead to several complications. The authors present a case of a 12-year-old girl with a radiolucent periapical lesion between tooth 35 and 36 where nocturnal exsanguinating bleeding started to occur from periodontal sulcus during orthodontic treatment. Diagnosis of an intraosseous hemangioma in the mandible was based on positive needle aspiration for blood, computed tomography and arteriography. At first the family chose to only follow-up the lesion but episodes of nocturnal hemorrhage were becoming more frequent and a treatment was requested. Embolization and dental extraction were performed in order to treat the lesion. After a follow-up period of 17 years no more cases of hemorrhage occurred and lesion regressed.

Bone resorption within the cervical spine due to vertebral arterial tortuosities is rarely observed in medical practice because the condition often lacks clinical symptoms. Traumatic complications involving the vertebral arteries are relatively common and occasionally very serious, but very few affect bone, appearing only when survival has been sufficiently long for a pseudoaneurysm to form. CT scans and MRI screening, practised increasingly today following traffic and sports accidents, incidentally show that arterial tortuosities that had stimulated bone resorption are relatively frequent. Only rarely do such tortuosities cause nerve compression or trigger orthopaedic problems, while large pseudoaneurysms and congenital absence of a vertebral pedicle may require surgery to stabilize the spine. There are few publications by palaeopathologists reporting such conditions of the cervical vertebrae. This contribution reports a case of a tiered bilateral tortuosity of the vertebral artery dating from the Early Middle Ages; it provides a basis by which to recognize this type of lesion in osteoarchaeology, and it attests to the fact that multiple tortuosities may lead to spinal instability in the form of spine sprain.

Most percutaneous vertebroplasty procedures are being performed in order to relieve pain in patients with severe osteoporosis and associated stable fractures of one or more vertebral bodies. In addition, vertebroplasty is also recommended for patients suffering from post-traumatic symptoms associated with vertebral fractures, patients with large angiomas positioned inside the vertebral body, with an increased risk for collapse fracture and also patients presenting with pain associated with vertebral body metastatic disease. On another aspect, it is possible that in isolated cases, an orthopedic surgeon confronted with a vertebra plana presentation will recommend bone cement injection into the vertebral bodies adjacent to the fractured one, in order to have a better and more robust substrate for placement of screws or other fixation devices. The aim of our study is to compare results attained by the Department of Interventional Radiology, in performing this procedure, with results attained by following the classical orthopedic treatment procedure, involving non-operative treatment, using medication and bracing varying from simple extension orthoses in order to limit spinal flexion, light bracing for contiguous fractures, presenting either angulation or compression, and for severe cases standard thoracolumbosacral orthoses (TLSOs).
The impact of posture and prolonged cyclic compressive loading on vertebral joint mechanics.

An in vitro biomechanics investigation exposing porcine functional spinal units (FSUs) to submaximal cyclic or static compressive forces while in a flexed, neutral, or extended posture. To investigate the combined effect of cyclically applied compressive force (e.g., vibration) and postural deviation on intervertebral joint mechanics. Independently, prolonged vibration exposure and non-neutral postures are known risk factors for development of low back pain and injury. However, there is limited basic scientific evidence to explain how the risk of low back injury from vibration exposure is modified by other mechanical factors. This work examined the influence of static postural deviation on vertebral joint height loss and compressive stiffness under cyclically applied compressive force. Forty-eight FSUs, consisting of 2 adjacent vertebrae, ligaments, and the intervening intervertebral disc were included in the study. Each specimen was randomized to 1 of 3 experimental posture conditions (neutral, flexed, or extended) and assigned to 1 of 2 loading protocols, consisting of (1) cyclic (1500 ± 1200 N applied at 5 Hz using a sinusoidal waveform, resulting in 0.2 g rms acceleration) or (2) 1500 N of static compressive force. RESULTS.: As expected, FSU height loss followed a typical first-order response in both the static and cyclic loading protocols, with the majority (~50%) of the loss occurring in the first 20 minutes of testing. A significant interaction between posture and loading protocol (P < 0.001) was noted in the magnitude of FSU height loss. Subsequent analysis of simple effects revealed significant differences between cyclic and static loading protocols in both a neutral (P = 0.016) and a flexed posture (P < 0.0001). No significant differences (P = 0.320) were noted between pre/postmeasurements of FSU compressive stiffness. Posture is an important mechanical factor to consider when assessing the risk of injury from cyclic loading to the lumbar spine.

Cadaveric motion segment experiment. To compare the strength in bending and compression of the human cervical spine and to investigate which structures resist bending the most. The strength of the cervical spine when subjected to physiologically reasonable complex loading is unknown, as is the role of individual structures in resisting bending. A total of 22 human cervical motion segments, 64 to 89 years of age, were subjected to complex loading in bending and compression. Resistance to flexion and to extension was measured in consecutive tests. Sagittal-plane movements were recorded at 50 Hz using an optical two-dimensional "MacReflex" system. Experiments were repeated 1) after surgical removal of the spinous process, 2) after removal of both apophyseal joints, and 3) after the disc-vertebral body unit had been compressed to failure. Results were analyzed using t tests, analysis of variance, and linear regression. Results were compared with published data for the lumbar spine. The elastic limit in flexion was reached at 8.5 degrees (SD, 1.7 degrees ) with a bending moment of 6.7 Nm (SD, 1.7 Nm). In extension, values were 9.5 degrees (SD, 1.6 degrees ) and 8.4 Nm (3.5 Nm), respectively. Spinous processes (and associated ligaments) provided 48% (SD, 17%) of the resistance to flexion. Apophyseal joints provided 47% (SD, 16%) of the resistance to extension. In compression, the disc-vertebral body units reached the elastic limit at 1.23 kN (SD, 0.46 Nm) and their ultimate compressive strength was 2.40 kN (SD, 0.96 kN). Strength was greater in male specimens, depended on spinal level and tended to decrease with age. The cervical spine has approximately 20% of the bending strength of the lumbar spine but 45% of its compressive strength. This suggests that the neck is relatively vulnerable in bending.

To study pathogenic features of pediatric hemangiomas, we successfully established a model in mice, by transplanting human hemangioma tissues. The hemangioma from the leg of a two-month-old infant was dissected and sliced into several pieces. During a careful surgical procedure, the hemangioma tissues were individually transplanted into skin incisions in anesthetized mice. The volume of the transplanted tumors was measured and the changes in shape recorded at 1 day, and at 1, 2, 3, 4, 5 and 6 months after the transplantation. HE dyeing, CD31 and Glut1 IHC were applied to tumors in the proliferation and involuting phases. Also, 10 survival tumors and 10 normal tissues from infants undergoing circumcisions (control tissues) were used to determine their Angiotensin 1 (Ang1), Angiotensin 2 (Ang2), Tie2, and endothelium growth factor (VEGF) expression levels by IHC method. We observed all the tumors going through the same stages, where after two months their volumes increased sharply and then after 4 months they all began to recede. During the proliferative phase, newly born capillaries could be seen and the tumor elasticity increased (bright red color). During the involuting phase, the color faded away and the tumors became harder and were almost gone by 6 months. During the first two months after transplantation, HE dyeing showed hypertrophied and proliferating endothelial cells accumulating inside the tumors with irregular cavities inside blood vessels being filled by them. During the involuting phase (at 4 months), the lumen in blood vessels was distinctly enlarged while fiber and adipose tissue had significantly deposited. The transplanted and original tumors tested positive for CD31 and Glut1 dyeing, without significant differences. Compared with control samples, the Ang1 expression of the transplanted tumor in both the hyperplasia and proliferative phases was stably low (p<0.05), while expressions of Ang2 and Tie2 were both stably high (p<0.05). The VEGF expression in the tumors, however, was high during the proliferative phase (p<0.05), while the VEGF of the involuting phase showed no significant differences from that of the normal samples (p>0.05). We showed the reliability of the mouse model in reflecting the pathologic evolution of the proliferation and involuting phases of infantile hemangiomas. Angiogenic mediators Ang1, Ang2 and Tie2 may be abnormally expressed and play important roles in the development of this angiogenic disease.

Cavernous malformations are characterized by enlarged vascular structures located in benign neural tissues within the cerebellum and spinal cord of the central nervous system. Cavernous hemangiomas (CHs) account for 5% to 12% of all spinal vascular malformations. We removed a hemorrhagic thoracic mass in a 40-year-old male patient who presented with progressive neurological deficits. We found it appropriate to present this case due to its rarity.

The enchondromatoses, Ollier's disease and Maffucci syndrome, are non-heritable developmental disorders characterized by multiple enchondromas (Olllier's) in association with hemangiomas (Maffucci). Glial neoplasms are reported in both disorders but a pathogenic mechanism underlying this association has not been identified. We report a case of anaplastic astrocytoma in a 23 year old man with Maffucci syndrome whose tumor carried a substitution mutation of arginine for cysteine at position 132 (R132C) of the isocitrate dehydrogenase 1 (IDH1) protein. This mutation, commonly found in Maffucci-associated enchondromas and hemangiomas, was not detected on routine immunohistochemical (IHC) analysis of the astrocytoma using the R132H mutation-specific antibody, commonly applied in clinical laboratories. The R132C mutation was detected by polymerase chain reaction (PCR) and subsequently confirmed using a SNaPshot assay. Because somatic mosaic IDH mutations are associated with enchondromas and hemangiomas in Maffucci syndrome, we looked for the R132C mutation in a hemangioma, peripheral blood mononuclear cells (PBMNC) and histologically normal brain surrounding the tumor from this patient. The mutation was present in the hemangioma, absent in PBMNC, and present in 2% of alleles in ‘normal’ brain. The low level in surrounding brain tissue is consistent with tumor cell infiltration, not mosaicism, as a S173T p53 mutation in the tumor showed similar results. Using IHC, we further demonstrated that the mutant IDH1 protein in this glioma functions as an oncometabolite. Two repressive histone trimethylation marks were strongly positive in the tumor, supporting a role for 2-hydroxyglutarate in the inhibition of histone demethylation. Together, these data demonstrate that an IDH1 mutation common in enchodromatoses underlies the association of glial tumors reported in both Ollier's disease and Maffucci syndrome.

Propranolol is the mainstay of treatment for infantile hemangioma. Despite its good safety profile, it is not risk-free. Guidelines for propranolol initiation and monitoring have been suggested, but protocols vary among practitioners. This study sought to assess the prevalence of adverse events and clinically significant fluctuations in hemodynamic parameters in children with infantile hemangioma during initiation of treatment with propranolol in a day-hospitalization setting. Children with infantile hemangioma treated with propranolol in a day-hospitalization department of a tertiary pediatric medical center in 2008-2014 were identified retrospectively. The pretreatment evaluation included clinical examination by a pediatric dermatologist and electrocardiography, echocardiography, and clinical examination by a pediatric cardiologist. The propranolol dosage was escalated from 0.5mg/kg/day to 2mg/kg/day, divided into 3 doses/day, over 3 days. Heart rate, blood pressure, and blood glucose level were measured before treatment onset and 60 min after the first two doses each day. The third dose was given at home. The cohort included 220 children aged 1 month to 5 years. No severe treatment-related adverse events were documented; 27 patients had minor side effects. There was a significant decrease in heart rate each day after the first two doses (p<0.001), and in systolic blood pressure, on day 2 (1mg/kg/day) after the first dose (p=0.01). Blood glucose level remained stable. The hemodynamic changes were clinically asymptomatic and did not require intervention. Propranolol treatment (2mg/kg/day in three doses) for infantile hemangioma is well tolerated and safe and may be administered and monitored in an ambulatory setting.

To report on the differential diagnosis of lyme arthritis and synovial hemangioma due to similar clinical and radiological signs and symptoms. A 15-year-old boy presented at the age of 9 with recurrent rather painless swelling of the right knee. Altogether four episodes lasting for 1-2 weeks each occurred over a period of 18 months before medical advice was sought. Physical examination revealed only a slightly limited range of motion. Living in an endemic area of borreliosis, he reported a tick bite 6 months prior to onset of his symptoms with erythema migrans and was treated for 10 days with amoxicillin. Serology revealed two positive unspecific bands in IgG immunoblot (p41 and 66) with slight positivity for ELISA. Ultrasound revealed synovial thickening and increased fluid. Despite the weak positive serology a diagnosis of lyme arthritis could not be excluded and intravenous antibiotic treatment with ceftriaxone was started. After two further relapses antiinflammatory therapy including intraarticular steroids were introduced with no long lasting effect. A chronical disease developed with alternate periods of swelling and almost complete remission. Ultrasound as well as MRI demonstrated ongoing signs of synovitis, therefore after further progression, a diagnostic arthroscopy was performed showing an inconspicuous knee joint. A second MRI showed focal suprapatellar enhancement and was followed by open arthrotomy revealing a histopathological proven synovial cavernous juxtaarticular hemangioma. To our knowledge, the differential diagnosis of lyme arthritis and synovial hemangioma has not yet been reported despite obvious clinical similarities. In conclusion, in children and adolescents synovial hemangioma has to be considered in differential diagnosis of recurrent knee swelling. Early diagnosis is important to prevent prolonged suffering from chronic joint swelling with probable joint damages, unnecessary treatment procedures and as well school and sports absenteeism.

Cervical subluxation and compressive myelopathy appears to be a cause of morbidity and mortality in captive Komodo dragons (Varanus komodoensis). Four cases of cervical subluxation resulting in nerve root compression or spinal cord compression were identified. Three were presumptively induced by trauma, and one had an unknown inciting cause. Two dragons exhibited signs of chronic instability. Cervical vertebrae affected included C1-C4. Clinical signs on presentation included ataxia, ambulatory paraparesis or tetraparesis to tetraplegia, depression to stupor, cervical scoliosis, and anorexia. Antemortem diagnosis of compression was only confirmed with magnetic resonance imaging or computed tomography. Treatment ranged from supportive care to attempted surgical decompression. All dragons died or were euthanatized, at 4 days to 12 mo postpresentation. Studies to define normal vertebral anatomy in the species are necessary to determine whether the pathology is linked to cervical malformation, resulting in ligament laxity, subsequent instability, and subluxation.
Glomeruloid hemangioma and POEMS syndrome.
Hernández Aragüés, I; Pulido Pérez, A; Ciudad Blanco, C; Parra Blanco, V; Suárez Fernández, R
2017-03-01
POEMS syndrome is a paraneoplastic manifestation associated with hematopoietic disorders such as multiple myeloma and Castleman disease. POEMS is an acronym for the main clinical features of the syndrome, namely, Polyneuropathy, Organomegaly, Endocrinopathy, M protein, and Skin abnormalities. Glomeruloid hemangiomas are considered to be a specific clinical marker of POEMS syndrome. However, while they are not pathognomonic, their presence should raise suspicion of this syndrome or alert clinicians to its possible future development, as these lesions can appear years before the onset of the syndrome. We report the cases of 2 women with plasma cell dyscrasias and sudden onset of lesions with a vascular appearance and histologic findings consistent with glomeruloid hemangioma. Recognition of this vascular tumor is important for the early diagnosis of POEMS syndrome. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.
Lymph node hemangioma in one-humped camel
Aljameel, M.A.; Halima, M.O.
2015-01-01
Hemangioma is a benign tumor of blood and lymphatic vessels. It is common in skin, mucosa and soft tissues, and its occurrence in lymph nodes is extremely rare. A 10 year-old she-camel was slaughtered at Nyala slaughterhouse, South Darfur State, Sudan. Grossly, the carcass was emaciated. The left ventral superficial cervical lymph node was enlarged, hard on palpation and protruded outside the body. Its cut surface was dark red in color and measured (18 cm) in diameter. Histopathologically, the sections revealed vascular masses were composed of non-encapsulated clusters of small and medium sized with thick and thin-walled, filled with blood, separated by courageous stroma and surrounded by closely packed proliferating capillaries. To the best of our knowledge, this is the first record of the left ventral superficial cervical lymph node hemangioma in a camel in the Sudan. PMID:26753134
New developments in the management of periocular capillary hemangioma in children.
Ni, Nina; Wagner, Rudolph S; Langer, Paul; Guo, Suqin
2011-01-01
The authors describe the theories of pathogenesis for capillary hemangioma and discuss the benefits and side effects of current treatment options, such as systemic and intralesional corticosteroids, laser therapy, and surgical excision. They also evaluate the recent systemic and topical applications of beta-blockers to treat infantile hemangioma. Although no major adverse events from beta-blocker treatment have been reported, the incidence of potential side effects such as bronchospasm, hypoglycemia, heart block, bradycardia, and congestive heart failure is unknown due to the novelty of the treatment. It has been postulated that topical application for localized superficial tumor may reduce systemic effects. Further research is necessary to compare the effectiveness of different treatments and to find the optimal dosing and delivery methods to minimize adverse effects in the treatment of this disorder.

A group of thirty-eight women under age 70 who sustained vertebral compression fractures during minor trauma included more postmenopausal smokers than a group of 34 similar women with fractures resulting from major trauma and more than a group of 572 other women. Advanced idiopathic osteoporosis occurring before age 65 was found rarely among nonsmokers. The percent cortical area at the second metacarpal midpoint was measured in 103 white women aged 40 to 49 years, and 208 white women aged 60 to 69 years. In the younger group, no quantitative differences were demonstrated between bones of the obese and the nonobese or between smokers and nonsmokers. In contrast, among the older group, postmenopausal smokers exhibited much more bone loss than did nonsmokers (P less than .001), and nonobese women demonstrated much more bone loss than did obese women, this difference being most striking among smokers.

Topical timolol maleate has recently gained popularity as a treatment for superficial infantile hemangiomas, but calculating a safe dose of timolol can be time consuming, which may limit the medication's use in fast-paced clinical environments. This report offers a simplified calculation of the maximum daily safe dosage as 1 drop of medication per kilogram of body weight. © 2018 Wiley Periodicals, Inc.

2016-10-01
Dumbbell-shaped epidural cavernous hemangiomas (CHs) are extremely rare, and they are easily misdiagnosed as spinal schwannomas. Herein, the authors report 1 rare case of dumbbell-shaped epidural CH in the thoracic spine. To the best of our knowledge, only a few cases of dumbbell-shaped epidural CHs in thoracic spine have been reported. Furthermore, the clinical characteristics and treatments for spinal epidural CHs were investigated and reviewed.

Cavernous hemangiomas of the gastrointestinal tract are quite rare and, until now, have been difficult to diagnose preoperatively due their nonspecific presentations and imaging features, as well as a lack of histologic description pertaining to small superficial biopsies such as those obtained endoscopically. We report a unique case of a 4 cm transmural cavernous hemangioma in the terminal ileum with literature review and describe a new histologic finding—the “endothelialized muscularis mucosae,” which was discovered upon review of the endoscopic biopsy and could potentially facilitate preoperative diagnosis of these lesions from endoscopic biopsies in the future. These lesions have classically required surgical resection in order to make a definitive diagnosis and rule out malignancy, with which they share many historical and radiographic features. Due to their potential to cause bowel obstruction, intussusception, perforation, and hemorrhage, these lesions may ultimately require surgical resection to relieve symptoms or prevent or treat complications—however, surgical planning and patient counseling could be greatly improved by a preoperative diagnosis. Therefore, gastroenterologists, pathologists, and surgeons should be aware of the “endothelialized muscularis mucosae” which can be very helpful in diagnosing GI cavernous hemangiomas from endoscopic biopsies.

Renal vascular lesions (RVL) are rare, and their morphological spectrum remains largely unknown, particularly in children. In this study, we characterize the clinicopathological features of RVL in a cohort of 12 children. Seven lesions were classified as previously recognized entities: vascular malformations (4), papillary endothelial hyperplasia (2), and pyogenic granuloma (lobular capillary hemangioma; 1). An eighth lesion showed nonspecific findings, which were interpreted as reactive during our review. The remaining 4 cases presented either prenatally, at birth, or shortly after birth and were morphologically similar. These were characterized by a peculiar pattern of capillary proliferation with entrapment of native renal structures, variable amounts of extramedullary hematopoiesis and reactive lymphocytes, foci of infarction and hemorrhage, and the presence of feeding and draining vessels at their periphery. To our knowledge, this represents a previously undescribed congenital vascular lesion involving the kidney, which we have descriptively and provisionally termed congenital capillary proliferation of the kidney (CCPK). While it is unclear whether CCPK represents a malformation or neoplastic proliferation, it shows overlapping features with congenital hemangioma of the liver (solitary congenital hepatic hemangioma) and congenital nonprogressive hemangioma (CNH) of the skin and soft tissue, suggesting a possible common pathogenesis among these 3 entities.

To evaluate, on a long-term basis, the safety and effectiveness of percutaneous alcohol embolization (PAE) combined with percutaneous vertebroplasty (PVP) as a sole treatment for aggressive vertebral haemangiomas (AVHs) with epidural extension. From 1996 to 2015, 26 consecutive patients (15 women [58%] and 11 men; mean age 51.8 years [range: 19-75 years]) underwent PAE combined with PVP (performed at day 15) for the treatment of 27 AVHs with epidural extension. Clinical outcome was evaluated with a mean delay of 88.3 ± 53.3 months (range: 22-217 months). The primary endpoint was pain relief evaluated with a visual analogue scale (VAS). Pre-procedure mean VAS score was 7.23 ± 1.3 and significantly improved at last follow-up (m = 3.11 ± 1.9; p < 0.001). Ten patients (38.5%) remained asymptomatic. Eighty-eight percent of the patients with neurosensory disorders had complete regression of these symptoms. Two of the three patients with motor deficit did not show any improvement. No major complication was recorded. PAE combined with PVP is a minimally invasive safe and effective therapeutic approach for AVH with epidural involvement, even on long-term clinical outcome. This technique appears mainly effective for pain and neurosensory symptoms, but seems less effective for motor deficit relief. • Combination of PAE with PVP is a safe technique. • PAE combined with PVP is an effective treatment for sensory symptoms. • This strategy seems less effective in patients with motor deficits.

Compressive fracture can produce profound changes to the mechanical profile of a spine segment. Minimally invasive repair has the potential to restore both function and structural integrity to an injured spine. Use of both hydrogels to address changes to the disc, combined with polymethyl methacrylate (PMMA) to address changes to the vertebral body, has the potential to facilitate repair. The purpose of this investigation was to determine if the combined use of hydrogel injection and PMMA could restore the mechanical profile of an axially injured spinal motion segment. This is a basic science study evaluating a combination of hydrogel injection and vertebroplasty on restoring mechanics to compressively injured porcine spine motion segments. Fourteen porcine spine motion segments were subject to axial compression until fracture using a dynamic servohydraulic testing apparatus. Rotational and compressive stiffness was measured for each specimen under the following conditions: initial undamaged, fractured, fatigue loading under compression, hydrogel injection, PMMA injection, and fatigue loading under compression. Group 1 received hydrogel injection followed by PMMA injection, whereas Group 2 received PMMA injection followed by hydrogel injection. This study was funded under a Natural Sciences and Engineering Research Council of Canada discovery grant. PMMA injection was found to alter the compressive stiffness properties of axially injured spine motion segments, restoring values from Groups 1 and 2 to 89.3%±29.3% and 81%±27.9% of initial values respectively. Hydrogel injection was found to alter the rotational stiffness properties, restoring specimens in Groups 1 and 2 to 151.5%±81% and 177.2%±54.9% of initial values respectively. Prolonged restoration of function was not possible, however, after further fatigue loading. Using this repair technique, replication of the mechanism of injury appears to cause a rapid deterioration in function of the motion segments. Containment of the hydrogel appears to be an issue with large breaches in the end plate, as it is posited to migrate into the cancellous bone of the vertebral body. Future work should attempt to evaluate methods in fully sealing the disc space. Copyright © 2016 Elsevier Inc. All rights reserved.

The number of reports describing osteoporotic vertebral fracture has increased as the number of elderly people has grown. Anterior decompression and fusion alone for the treatment of vertebral collapse is not easy for patients with comorbid medical problems and severe bone fragility. The purpose of the present study was to evaluate the efficacy of one-stage posterior instrumentation surgery for the treatment of osteoporotic vertebral collapse with neurological deficits. A consecutive series of 21 patients who sustained osteoporotic vertebral collapse with neurological deficits were managed with posterior decompression and short-segmental pedicle screw instrumentation augmented with ultra-high molecular weight polyethylene (UHMWP) cables with or without vertebroplasty using calcium phosphate cement. The mean follow-up was 42 months. All patients showed neurologic recovery. Segmental kyphotic angle at the instrumented level was significantly improved from an average preoperative kyphosis of 22.8–14.7 at a final follow-up. Spinal canal occupation was significantly reduced from an average before surgery of 40.4–19.1% at the final follow-up. Two patients experienced loosening of pedicle screws and three patients developed subsequent vertebral compression fractures within adjacent segments. However, these patients were effectively treated in a conservative fashion without any additional surgery. Our results indicated that one-stage posterior instrumentation surgery augmented with UHMWP cables could provide significant neurological improvement in the treatment of osteoporotic vertebral collapse.

To assess whether percutaneous vertebroplasty results in more pain relief than a sham procedure in patients with acute osteoporotic compression fractures of the vertebral body. Randomised, double blind, sham controlled clinical trial. Four community hospitals in the Netherlands, 2011-15. 180 participants requiring treatment for acute osteoporotic vertebral compression fractures were randomised to either vertebroplasty (n=91) or a sham procedure (n=89). Participants received local subcutaneous lidocaine (lignocaine) and bupivacaine at each pedicle. The vertebroplasty group also received cementation, which was simulated in the sham procedure group. Main outcome measure was mean reduction in visual analogue scale (VAS) scores at one day, one week, and one, three, six, and 12 months. Clinically significant pain relief was defined as a decrease of 1.5 points in VAS scores from baseline. Secondary outcome measures were the differences between groups for changes in the quality of life for osteoporosis and Roland-Morris disability questionnaire scores during 12 months' follow-up. The mean reduction in VAS score was statistically significant in the vertebroplasty and sham procedure groups at all follow-up points after the procedure compared with baseline. The mean difference in VAS scores between groups was 0.20 (95% confidence interval -0.53 to 0.94) at baseline, -0.43 (-1.17 to 0.31) at one day, -0.11 (-0.85 to 0.63) at one week, 0.41 (-0.33 to 1.15) at one month, 0.21 (-0.54 to 0.96) at three months, 0.39 (-0.37 to 1.15) at six months, and 0.45 (-0.37 to 1.24) at 12 months. These changes in VAS scores did not, however, differ statistically significantly between the groups during 12 months' follow-up. The results for secondary outcomes were not statistically significant. Use of analgesics (non-opioids, weak opioids, strong opioids) decreased statistically significantly in both groups at all time points, with no statistically significant differences between groups. Two adverse events occurred in the vertebroplasty group: one respiratory insufficiency and one vasovagal reaction. Percutaneous vertebroplasty did not result in statistically significantly greater pain relief than a sham procedure during 12 months' follow-up among patients with acute osteoporotic vertebral compression fractures.

A primary intraosseous hemangioma (IOH) of the orbital bone is extremely rare. The preferred method of treatment for IOH is total surgical excision with reconstruction. Herein, the authors describe a patient with an orbital roof IOH and the unexpected complications of ptosis and deteriorated exophthalmos. These findings showed that the total surgical excision and subsequent reconstruction provided adequate decompression and prevented further ocular complications from the orbital wall defect.

Capillary hemangiomas are common soft tissue tumors on the skin or mucosa of the head and neck in the early childhood, but very rare in the neuraxis. A 47-year-old man presented with one month history of back pain on the lower thoracic area, radiating pain to both legs, and hypesthesia below T7 dermatome. Thoracic spine MRI showed 1×1.3×1.5 cm, well-defined intradural mass at T6-7 disc space level, which showed isointensity to spinal cord on T1, heterogeneous isointensity on T2-weighted images, and homogeneous strong enhancement. The patient underwent T6-7 total laminotomy, complete tumor removal and laminoplasty. Histologically, the mass showed a capsulated nodular lesion composed of capillary-sized vascular channels, which were tightly packed into nodules separated by fibrous septa. These features were consistent with capillary hemangioma. PMID:21082058

Type and timing of treatment for symptomatic hemangiomas in pregnant females are challenging due to fetus survival and conflicts in neurological recovery. In this article, we report a 40-year-old female patient at pregnancy week 23 with a complicated hemangioma at T1 level. Physical examination revealed an incomplete spastic paraplegia. Patient did not accept any surgery due to child's death risk. Patient was started corticoid treatment and no more weight bearing was allowed. At the 28th week of pregnancy, the patient underwent cesarean section immediately followed by selective arterial embolization, decompression, fixation, and radiotherapy. At two-year follow-up, the patient was pain free, without any signs of local recurrence and with complete neurological recovery. A multidisciplinary approach is mandatory to save the life of the fetus without damaging the spinal cord functions of the mother.

2016-11-01
A two-month-old boy visited the hospital due to unexpected cutaneous purpura and thrombocytopenia for 2 days. The physical examination revealed a purple mass on the back. The soft tissue color Doppler ultrasound showed rich blood signals in the tissue, and the results of bone marrow puncture indicated an increased number of megakaryocytes. After the treatment with hormone and gamma globulin, the platelet count rapidly increased and maintained at a normal level. Meanwhile, the boy was given oral administration of propranolol. He was followed up for 4 months and the volume of the mass on the back was reduced significantly. He had a definite diagnosis of hemangioma and immune thrombocytopenia. As for the patients with hemangioma complicated by thrombocytopenia, knowledge of Kasabach-Merritt syndrome should be enhanced and there should be a clarification of the association between thrombocytopenia and hemangioma. There should also be an alertness for thrombocytopenia of other causes.

Twenty-three patients with symptomatic giant hemangioma of the liver were treated by surgery between 1979 and 1996 at the department of General Surgery, Faculty of Medicine, University of Çukurova. Twenty-three enucleations were performed in 21 patients, left lateral segmentectomy in one patient and enucleation plus left lobectomy in one patient. The tumors were enucleated along the interface between the hemangioma and normal liver tissue. The diameters of the tumors ranged from 5×5 to 25×15 cm. The mean blood loss for enucleations was 525 ml (range 500–1000 ml). There was no mortality and no postoperative bleeding. Three patients had postoperative complications. Enucleation is the best surgical technique for symptomatic giant hemangioma of the liver. It may be performed with no mortality, low morbidity and the preservation of all normal liver parenchyma.

To investigate the relationship between abdominal chemoradiation (CRT) for locally advanced cancers and bone mineral density (BMD) reduction in the vertebral spine. Data from 272 patients who underwent abdominal radiation therapy from January 1997 to May 2015 were retrospectively reviewed. Forty-two patients received computed tomography (CT) scans of the abdomen prior to initiation and at least twice after radiation therapy. Bone attenuation (in Hounsfield unit) (HU) measurements were collected for each vertebral level from T7 to L5 using sagittal CT images. Radiation point dose was obtained at each mid-vertebral body from the radiation treatment plan. Percent change in bone attenuation (Δ%HU) between baseline and post-radiation therapy were computed for each vertebral body. The Δ%HU was compared against radiation dose using Pearson's linear correlation. Abdominal radiotherapy caused significant reduction in vertebral BMD as measured by HU. Patients who received only chemotherapy did not show changes in their BMD in this study. The Δ%HU was significantly correlated with the radiation point dose to the vertebral body (R=-0.472, P<0.001) within 4-8 months following RT. The same relationship persisted in subsequent follow up scans 9 months following RT (R=-0.578, P<0.001). Based on the result of linear regression, 5 Gy, 15 Gy, 25 Gy, 35 Gy, and 45 Gy caused 21.7%, 31.1%, 40.5%, 49.9%, and 59.3% decrease in HU following RT, respectively. Our generalized linear model showed that pre-RT HU had a positive effect (β=0.830) on determining post-RT HU, while number of months post RT (β=-0.213) and radiation point dose (β=-1.475) had a negative effect. A comparison of the predicted versus actual HU showed significant correlation (R=0.883, P<0.001) with the slope of the best linear fit=0.81. Our model's predicted HU were within ±20 HU of the actual value in 53% of cases, 70% of the predictions were within ±30 HU, 81% were within ±40 HU, and 90% were within ±50 HU of the actual post-RT HU. Four of 42 patients were found to have vertebral body compression fractures in the field of radiation. Patients who receive abdominal chemoradiation develop significant BMD loss in the thoracic and lumbar vertebrae. Treatment-related BMD loss may contribute to the development of vertebral compression fractures. A predictive model for post-CRT BMD changes may inform bone protective strategies in patients planned for abdominal CRT. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

A 19-year-old female Bengal tiger (Panthera tigris tigris) was presented with hind limb weakness, ataxia and respiratory distress. Computed tomography revealed a mass between the left side of the T7 vertebra and the base of the left 7th rib. The tiger then died, and necropsy was performed. Grossly, the vertebral mass was 6 × 5.7 × 3 cm, and invaded the adjacent vertebral bone and compressed the T7 spinal cord. Histologically, the mass was composed of large, clear, vacuolated and polygonal cells with osteochondral matrix. Cellular and nuclear atypia were moderate. The vacuolated cells stained positively for cytokeratin and vimentin and negatively for S-100. Based on these findings, the present case was diagnosed as a vertebral chordoma; the first report in a tiger. PMID:25766770

Introduction Osteoporotic vertebral compression fractures (OVCFs) commonly cause both acute and chronic back pain, substantial spinal deformity, functional disability and decreased quality of life and increase the risk of future vertebral fractures and mortality. Percutaneous vertebroplasty (PVP), balloon kyphoplasty (BK) and non-surgical treatment (NST) are mostly used for the treatment of OVCFs. However, which treatment is preferred is unknown. The purpose of this study is to comprehensively review the literature and ascertain the relative efficacy and safety of BK, PVP and NST for patients with OVCFs using a Bayesian network meta-analysis. Methods and analysis We will comprehensively search PubMed, EMBASE and the Cochrane Central Register of Controlled Trials, to include randomided controlled trials that compare BK, PVP or NST for treating OVCFs. The risk of bias for individual studies will be assessed according to the Cochrane Handbook. Bayesian network meta-analysis will be performed to compare the efficacy and safety of BK, PVP and NST. The quality of evidence will be evaluated by GRADE. Ethics and dissemination Ethical approval and patient consent are not required since this study is a meta-analysis based on published studies. The results of this network meta-analysis will be submitted to a peer-reviewed journal for publication. PROSPERO registration number CRD42016039452; Pre-results. PMID:28093431

Weight bearing by the spinal column during upright posture often plays a role in the common problem of low back pain. Therefore, we developed a non-ferromagnetic spinal compression harness to enable MRI investigations of the spinal column during axial loading. Human subjects were fitted with a Nest and a footplate which were connected by adjustable straps to an analog load cell. MRI scans of human subjects (5 males and 1 female with age range of 27-53 yrs) during loaded and unloaded conditions were accomplished with a 1.5 Tesla GE Signa scanner. Studies of two subjects undergoing sequentially increasing spinal loads revealed significant decreases (r(sup 2) = 0.852) in spinal length between T4 and L5 culminating in a 1.5 to 2% length decrease during loading with 75% body weight. Sagittal vertebral body angles of four subjects placed under a constant 50% body weight load for one hour demonstrated increased lordotic and kyphotic curvatures. In the lumbar spine, the L2 vertebral body experienced the greatest angular change (-3 deg. to -5 deg.) in most subjects while in the thoracic spine, T4 angles increased from the unloaded state by +2 deg. to +9 deg. Overall, our studies demonstrate: 1) a progressive, although surprisingly small, decrease in spinal length with increasing load and 2) relatively large changes in spinal column angulation with 50% body weight.

This is a study of vertebral deformities in ornamental koi based on computed radiography and skeletons cleaned by dermestid beetles (Dermestes maculatus). All koi developed gradual onset of swimming abnormalities as adults. Extensive intervertebral osteophyte formation correlated with age of fish and was associated with hindquarter paresis in one koi. Vertebral compression and fusion were the most common spinal deformities occurring at multiple sites, similar to findings in other farmed fish. Site-specific spinal deformities were thought to develop due to differences in swimming behaviour and rates of vertebral growth. One koi had offspring with spinal deformities. Spinal deformities are significant problems in both European and Australian food fish hatcheries. The heritability of vertebral deformities in farmed fish is reportedly low unless there is concurrent poor husbandry or nutritional deficiencies. The specific aetiologies for vertebral deformities in koi in this study could not be ascertained. Current knowledge on spinal deformities in the better studied European food fish species suggests multifactorial aetiologies. Future research should include prospective longitudinal studies of larger numbers of koi from hatch and consideration of all potential risk factors such as husbandry, nutrition, temperature, photoperiod and genetics. © 2016 John Wiley & Sons Ltd.

Infantile hemangiomas (IH) are common tumors for which there is no validated disease-specific instrument to measure the quality of life in infants and their parents/caregivers during the critical first months of life. This study prospectively developed and validated a quality-of-life instrument for patients with IH and their parents/caregivers and correlated demographic and clinical features to the effects on the quality of life. A total of 220 parents/caregivers completed the 35-item Infantile Hemangioma Quality-of-Life (IH-QoL) instrument and provided demographic information. The dimensionality of the items was evaluated using factor analysis, with results suggesting four factors: child physical symptoms, child social interactions, parent emotional functioning, and parent psychosocial functioning. Each factor fit the Rasch measurement model with acceptable fit index (mean square <1.4) and demonstrated excellent internal consistency, with alpha ranging from 0.76 to 0.88. The final instrument consists of four scales with a total of 29 items. Content validity was verified by analyzing parents' responses to an open-ended question. Test-retest reliability at a 48-hour interval was supported by a total IH-QoL intraclass correlation coefficient of 0.84. Certain clinical characteristics of hemangioma, including those located on the head and neck, in the proliferative stage, and requiring treatment, are associated with a greater impact on QoL.

Congenital vertebral malformations are common in brachycephalic "screw-tailed" dog breeds such as French bulldogs, English bulldogs, Boston terriers, and pugs. The aim of this retrospective study was to determine whether a radiographic classification scheme developed for use in humans would be feasible for use in these dog breeds. Inclusion criteria were hospital admission between September 2009 and April 2013, neurologic examination findings available, diagnostic quality lateral and ventro-dorsal digital radiographs of the thoracic vertebral column, and at least one congenital vertebral malformation. Radiographs were retrieved and interpreted by two observers who were unaware of neurologic status. Vertebral malformations were classified based on a classification scheme modified from a previous human study and a consensus of both observers. Twenty-eight dogs met inclusion criteria (12 with neurologic deficits, 16 with no neurologic deficits). Congenital vertebral malformations affected 85/362 (23.5%) of thoracic vertebrae. Vertebral body formation defects were the most common (butterfly vertebrae 6.6%, ventral wedge-shaped vertebrae 5.5%, dorsal hemivertebrae 0.8%, and dorso-lateral hemivertebrae 0.5%). No lateral hemivertebrae or lateral wedge-shaped vertebrae were identified. The T7 vertebra was the most commonly affected (11/28 dogs), followed by T8 (8/28 dogs) and T12 (8/28 dogs). The number and type of vertebral malformations differed between groups (P = 0.01). Based on MRI, dorsal, and dorso-lateral hemivertebrae were the cause of spinal cord compression in 5/12 (41.6%) of dogs with neurologic deficits. Findings indicated that a modified human radiographic classification system of vertebral malformations is feasible for use in future studies of brachycephalic "screw-tailed" dogs. © 2014 American College of Veterinary Radiology.

To test interobserver variability of ADC measurements and compare the diagnostic performances of free-breathing diffusion-weighted (FBDW) with that of T2-weighted FSE (T2WFSE) MR imaging for differentiating between cavernous hemangiomas and untreated malignant hepatic neoplasms. Thirty-five patients with cavernous hemangiomas and 35 with untreated hepatic malignant neoplasms had FBDW and T2WFSE MR imaging. Hepatic lesions were characterized with ADC measurement and visual evaluation. Interobserver agreement for ADC measurement was calculated. Association between ADC value and lesion type was assessed using univariate analysis. Sensitivity, specificity and accuracy of ADC values and visual evaluation of MR images for the diagnosis of untreated malignant hepatic neoplasm were compared. ADC measurements showed excellent interobserver correlation (intraclass correlation coefficient=0.980). Malignant neoplasms had lower ADC values than hemangiomas for the two observers (1.11×10(-3) mm2/s±.21×10(-3) vs. 1.77×10(-3) mm2/s±.29×10(-3) for observer 1 and 1.11×10(-3) mm2/s±.19×10(-3) vs. 1.79×10(-3) mm2/s±.32×10(-3) for observer 2) and univariate analysis found significant correlations between lesion type and ADC values. Depending on ADC threshold value, accuracy for the diagnosis of malignant neoplasm varied from 82.9% to 94.3%. Using visual evaluation, FBDW showed better specificity and accuracy than T2WFSE MR images for the diagnosis of malignant neoplasm (97.1% vs. 77.1% and 94.3% vs. 62.9%, respectively). FBDW imaging provides reproducible quantitative information and surpasses the value of T2WFSE MR imaging for differentiating between cavernous hemangiomas and untreated malignant hepatic neoplasms.

Oral propranolol has been used to treat complicated infantile hemangiomas, although data from randomized, controlled trials to inform its use are limited. We performed a multicenter, randomized, double-blind, adaptive, phase 2-3 trial assessing the efficacy and safety of a pediatric-specific oral propranolol solution in infants 1 to 5 months of age with proliferating infantile hemangioma requiring systemic therapy. Infants were randomly assigned to receive placebo or one of four propranolol regimens (1 or 3 mg of propranolol base per kilogram of body weight per day for 3 or 6 months). A preplanned interim analysis was conducted to identify the regimen to study for the final efficacy analysis. The primary end point was success (complete or nearly complete resolution of the target hemangioma) or failure of trial treatment at week 24, as assessed by independent, centralized, blinded evaluations of standardized photographs. Of 460 infants who underwent randomization, 456 received treatment. On the basis of an interim analysis of the first 188 patients who completed 24 weeks of trial treatment, the regimen of 3 mg of propranolol per kilogram per day for 6 months was selected for the final efficacy analysis. The frequency of successful treatment was higher with this regimen than with placebo (60% vs. 4%, P<0.001). A total of 88% of patients who received the selected propranolol regimen showed improvement by week 5, versus 5% of patients who received placebo. A total of 10% of patients in whom treatment with propranolol was successful required systemic retreatment during follow-up. Known adverse events associated with propranolol (hypoglycemia, hypotension, bradycardia, and bronchospasm) occurred infrequently, with no significant difference in frequency between the placebo group and the groups receiving propranolol. This trial showed that propranolol was effective at a dose of 3 mg per kilogram per day for 6 months in the treatment of infantile hemangioma.

The uncommon variant of degenerative hip joint disease, termed rapidly progressive osteoarthritis, and highlighted by severe joint space loss and osteochondral disintegration, is well established. We present a similar unusual subset in the lumbar spine termed destructive discovertebral degenerative disease (DDDD) with radiological features of vertebral malalignment, severe disc resorption, and "bone sand" formation secondary to vertebral fragmentation. Co-existing metabolic bone disease is likely to promote the development of DDDD of the lumbar spine, which presents with back pain and sciatica due to nerve root compression by the "bone sand" in the epidural space. MRI and CT play a complimentary role in making the diagnosis.

We developed and validated a fully articulated model of the thoracolumbar spine in opensim that includes the individual vertebrae, ribs, and sternum. To ensure trunk muscles in the model accurately represent muscles in vivo, we used a novel approach to adjust muscle cross-sectional area (CSA) and position using computed tomography (CT) scans of the trunk sampled from a community-based cohort. Model predictions of vertebral compressive loading and trunk muscle tension were highly correlated to previous in vivo measures of intradiscal pressure (IDP), vertebral loading from telemeterized implants and trunk muscle myoelectric activity recorded by electromyography (EMG).

This article presents a 56-year-old obese female who presented with back pain and progressive weakness in her lower limbs for three months. She was bed-ridden for one week before reporting to our hospital. Plain radiographs showed vertical striations in multiple vertebrae classical of haemangioma. Magnetic resonance imaging (MRI) spine revealed multiple thoracic and lumbar vertebral haemangiomas. Extra osseous extension of haemangioma at T12 was causing spinal cord compression. Two-stage surgery was performed with absolute alcohol (ethanol) injection followed by pedicle screw fixation and decompression with tricortical iliac crest bone graft into the vertebral body. Postoperatively rapid neurological improvement was seen. After three weeks, she could walk independently. One year later, computed tomography showed complete incorporation of bone graft and maintained vertebral body height. MRI showed complete resolution of the cord edema at T12. These findings indicated diminished vascularity of the tumor. PMID:25187869
[Low back pain vs. leg dominant pain].
Kovac, Ida
2011-01-01
There are two patterns of back pain: 1) back-dominant pain and 2) leg pain dominant, greater than back pain. The causes of back pain are very different and numerous, but mostly are due to vertebral, mechanical etiology, and rarely because of non vertebral, visceral etiology. Leg pain greater than back pain is mostly disease of spinal nerve root, generally presented by radicular pain in a dermatomal distribution. Mechanical compression of spinal roots, caused by disc herniation or by spinal stenosis, results in radicular symptoms. Rarely, in about 1% of patients, there are some other reasons except vertebral mechanical cause, like infection, tumor or fracture. There are several causes of pseudoradicular pain like periferal neuropathy, myifascial syndromes, vascular diseases, osteoarthritis. Spondylarthropathies should be taken in cosideration as well. A complete history and physical examination is important to determine further diagnostic evaluation and to provide eficient therapy.
Arterial relationships to the nerves and some rigid structures in the posterior cranial fossa.
Surchev, N
2008-09-01
The close relationships between the cranial nerves and the arterial vessels in the posterior cranial fossa are one of the predisposing factors for artery-nerve compression. The aim of this study was to examine the relationships of the vertebral and basilar arteries to some skull and dural structures and the nerves in the posterior cranial fossa. For this purpose, the skull bases and brains of 70 cadavers were studied. The topographic relationships of the vertebral and basilar arteries to the cranial nerves in the posterior cranial fossa were studied and the distances between the arteries and some osseous formations were measured. The most significant variations in arterial position were registered in the lower half of the basilar artery. Direct contact with an artery was established for the hypoglossal canal, jugular tubercle, and jugular foramen. The results reveal additional information about the relationships of the nerves and arteries to the skull and dural formations in the posterior cranial fossa. New quantitative information is given to illustrate them. The conditions for possible artery-nerve compression due to arterial dislocation are discussed and two groups (lines) of compression points are suggested. The medial line comprises of the brain stem points, usually the nerve root entry/exit zone. The lateral line includes the skull eminences, on which the nerves lie, or skull and dural foramina through which they exit the cranial cavity. (c) 2008 Wiley-Liss, Inc.

Percutaneous vertebroplasty with polymethylmethacrylate (PMMA) is an effective procedure for relieving pain due to vertebral body compression fractures. The technique employs iodinated contrast venography to exclude needle placement directly within the basivertebral complex. We present two cases in which carbon dioxide (CO{sub 2}) and gadopentetate dimeglumine venography was used to guide percutaneous vertebroplasty in patients with a contraindication to iodinated contrast.

Cement pulmonary embolism after vertebroplasty.

2013-01-01
In recent years, the use of vertebral cementing techniques for vertebroplasty and kyphoplasty has spread for the treatment of pain associated with osteoporotic vertebral compression fractures. This is also associated with the increased incidence of complications related with these procedures, the most frequent being originated by leakage of cementation material. Cement can escape into the vertebral venous system and reach the pulmonary circulation through the azygous system and cava vein, producing a cement embolism. This is a frequent complication, occurring in up to 26% of patients undergoing vertebroplasty but, since most patients have no clinical or hemodynamical repercussion, this event usually goes unnoticed. However, some serious, and even fatal cases, have been reported. We report the case of a 74-year-old male patient who underwent vertebroplasty for persistent pain associated with osteoporotic L3 vertebral fracture and who developed a cement leak into the cava vein and right pulmonary artery during the procedure. Although he developed a pulmonary cement embolism, the patient remained asymptomatic and did not present complications during follow-up. Copyright © 2012 Elsevier España, S.L. All rights reserved.

2014-01-01
Background. Infantile hemangiomas (IHs) are the most common benign tumours of infancy. Propranolol has recently been reported to be a highly effective treatment for IHs. This study aimed to evaluate the efficacy and side effects of propranolol for treatment of complicated cases of IHs. Patients and Methods. This prospective clinical study included 30 children with huge or complicated IHs; their ages ranged from 2 months to 1 year. They were treated by oral propranolol. Treatment outcomes were clinically evaluated. Results. Superficial cutaneous hemangiomas began to respond to propranolol therapy within one to two weeks after the onset of treatment. The mean treatment period that was needed for the occurrence of complete resolution was 9.4 months. Treatment with propranolol was well tolerated and had few side effects. No rebound growth of the tumors was noted when propranolol dosing stopped except in one case. Conclusion. Propranolol is a promising treatment for IHs without obvious side effects. However, further studies with longer follow-up periods are needed. PMID:24899888

The aim of this study is to describe vision loss caused by central retinal artery and posterior ciliary artery occlusion as a consequence of sclerotherapy with a polidocanol injection to a glabellar hemangioma. An 18-year-old man underwent direct injection with a 23-gauge needle of 1 mL of a polidocanol-carbon dioxide emulsion into the glabellar subcutaneous hemangioma under ultrasound visualization of the needle tip by radiologists. He developed lid swelling the next day, and 3 days later at referral, the visual acuity in the left eye was no light perception. Funduscopy revealed central retinal artery occlusion and fluorescein angiography disclosed nomore » perfusion at all in the left fundus, indicating concurrent posterior ciliary artery occlusion. The patient also showed mydriasis, blepharoptosis, and total external ophthalmoplegia on the left side. Magnetic resonance imaging demonstrated the swollen medial rectus muscle. In a month, blepharoptosis and ophthalmoplegia resolved but the visual acuity remained no light perception.

Infantile hemangioendothelioma is the most common symptomatic vascular liver tumor of infancy. It is considered a benign tumor; however, aggressive behavior is occasionally seen microscopically, and rarely distant metastases have been reported. The exact incidence of infantile hemangioendothelioma is difficult to determine because often it has been either misdiagnosed or mislabeled as cavernous hemangioma in the literature. Cavernous hemangioma is the most common primary liver tumor in older age groups but is rarely found in infants as a clinically significant tumor. Levick and Rubie were the first to recognize an association between hemangioendothelioma of the liver and congestive heart failure,more » and there were subsequent reports substantiating this association. However, it is our impression and the finding of others that congestive heart failure is distinctly less common than abdominal mass or hepatomegaly as the presenting sign in infantile hemangioendothelioma. Congestive heart failure is rarely a feature of cavernous hemangioma. Because of the errors in terminology and questions regarding clinical presentation, a radiologic-pathologic-clinical correlation study of infantile hemangioendothelioma and review of the literature was undertaken.« less

To compare safety and efficacy of percutaneous vertebroplasty (PVP) when treating up to three vertebrae or more than three vertebrae per session. We prospectively compared two groups of patients with symptomatic vertebral fractures who had no significant response to conservative therapy. Pathologic substrate included osteoporosis (n = 77), metastasis (n = 24), multiple myeloma (n = 13), hemangioma (n = 15), and lymphoma (n = 1). Group A patients (n = 94) underwent PVP of up to three treated vertebrae (n = 188). Group B patients (n = 36) underwent PVP with more than three treated vertebrae per session (nmore » = 220). Decreased pain and improved mobility were recorded the day after surgery and at 12 and 24 months after surgery per clinical evaluation and the use of numeric visual scales (NVS): the Greek Brief Pain Inventory, a linear analogue self-assessment questionnaire, and a World Health Organization questionnaire. Group A presented with a mean pain score of 7.9 {+-} 1.1 NVS units before PVP, which decreased to 2.1 {+-} 1.6, 2.0 {+-} 1.5 and 2.0 {+-} 1.5 NVS units the day after surgery and at 12 and 24 months after surgery, respectively. Group B presented with a mean pain score of 8.1 {+-} 1.3 NVS units before PVP, which decreased to 2.2 {+-} 1.3, 2.0 {+-} 1.5, and 2.1 {+-} 1.6 NVS units the day after surgery and at 12 and 24 months after surgery, respectively. Overall pain decrease and mobility improvement throughout the follow-up period presented no statistical significance neither between the two groups nor between different underlying aetiology. Reported cement leakages presented no statistical significance between the two groups (p = 0.365). PVP is an efficient and safe technique for symptomatic vertebral fractures independently of the vertebrae number treated per session.« less

Two different procedures, used for percutaneous augmentation of vertebral compression fractures were compared, with respect to height restoration and maintenance after cyclic loading. Additionally the impact of the cement volume used was investigated. Wedge compression fractures were created in 36 human cadavaric vertebrae (T10-L3). Twenty-seven vertebrae were treated with the SpineJack® with different cement volumes (maximum, intermediate, and no cement), and 9 vertebrae were treated with Balloon Kyphoplasty. Vertebral heights were measured pre- and postfracture as well as after treatment and loading. Cyclic loading was performed with 10,000cycles (1Hz, 100-600N). The average anterior height after restoration was 85.56% for Kyphoplasty; 96.20% for SpineJack® no cement; 93.44% for SpineJack® maximum and 96% for the SpineJack® intermediate group. The average central height after restoration was 93.89% for Kyphoplasty; 100.20% for SpineJack® no cement; 99.56% for SpineJack® maximum and 101.13% for the SpineJack® intermediate group. The average anterior height after cyclic loading was 85.33 % for Kyphoplasty; 87.30% in the SpineJack® no cement, 92% in the SpineJack® maximum and 87% in the SpineJack® intermediate group. The average central height after cyclic loading was 92% for Kyphoplasty; 93.80% in the SpineJack® no cement; 98.56% in the SpineJack® maximum and 94.25% in the SpineJack® intermediate group. Height restoration was significantly better for the SpineJack® group compared to Kyphoplasty. Height maintenance was dependent on the cement volume used. The group with the SpineJack® without cement nevertheless showed better results in height maintenance, yet the statistical significance could not be demonstrated. Copyright © 2013 Elsevier Ltd.

Resection of the hemangioma located in the caudate lobe is a major challenge in current liver surgery. This study aimed to present our surgical technique for this condition. Two consecutive patients with symptomatic hepatic hemangioma undergoing caudate lobectomy were investigated retrospectively. First, all the blood inflow of hemangioma from the portal vein and the hepatic artery at the base of the umbilical fissure was dissected. After the tumors became soft and tender, the short hepatic veins and the ligaments between the secondary porta hepatis were severed. At last the tumors were resected from the right lobe of the liver. The whole process was finished by a left-sided approach. Blood lost in Case 1 was 1650 mL because of ligature failing in one short hepatic vein, and in the other case, 210 mL. Operation time was 236 minutes and 130 minutes, respectively. Postoperative hospital stays were 11 and 5 days, respectively. The diameter of tumors was 9.0 cm and 6.5 cm. Case 1 required blood transfusion during surgery. No complications such as biliary fistula, postoperative bleeding, and liver failure occurred. The left-sided approach produced the best results for caudate lobe resection in our cases. The patients who recovered are living well and asymptomatic. Caudate lobectomy can be performed safely and quickly by a left-sided approach, which is carried out with optimized perioperative management and innovative surgical technique.

Lumbosacral cutaneous vascular anomalies associated with neural tube defects are frequently described in the literature as "hemangiomas." The classification system for pediatric vascular anomalies developed by the International Society for the Study of Vascular Anomalies provides a framework to accurately diagnose these lesions. To apply this classification to vascular cutaneous anomalies overlying myelodysplasias. A retrospective analysis of patients with neural tube defects and lumbosacral cutaneous vascular lesions was performed. All eligible patients had detailed histopathologic analysis of skin and spinal cord/placode lesions. Clinical and radiologic features were analyzed. Conventional histology and GLUT-1 immunostaining were performed to differentiate infantile capillary hemangiomas from capillary vascular malformations. Ten cases with cutaneous lesions associated with neural tube defects were reviewed. Five lesions were diagnosed as infantile capillary hemangiomas based upon histology and positive GLUT-1 endothelial reactivity. These lesions had a strong association with dermal sinus tracts. No reoperations were required for residual intraspinal vascular lesions, and overlying cutaneous vascular anomalies involuted with time. The remaining 5 lesions were diagnosed as capillary malformations. These occurred with both open and closed neural tube defects, did not involute, and demonstrated enlargement and darkening due to vascular congestion. The International Society for the Study of Vascular Anomalies scheme should be used to describe the cutaneous vascular lesions associated with neural tube defects: infantile capillary hemangiomas and capillary malformations. We advocate that these lesions be described as "vascular anomalies" or "stains" pending accurate diagnosis by clinical, histological, and immunohistochemical evaluations.

The aim of this on-going research project is to assess the influence of bone microarchitecture on the mechanical performance of trabecular bone. A testing chain consist-ing of three steps was established: 1) micro computed tomography (μCT) imaging of human trabecular bone; 2) building of models of the bone from a light-sensitive polymer using Rapid Prototyping (RP); 3) mechanical testing of the models in a material testing machine. A direct resampling procedure was developed to convert μCT data into the format of the RP machine. Standardized parameters for production and testing of the plastic models were established by use of regular cellular structures. Next, normal, osteoporotic, and extreme osteoporotic vertebral trabecular bone architectures were re-produced by RP and compression tested. We found that normal architecture of vertebral trabecular bone exhibit behaviour characteristic of a cellular structure. In normal bone the fracture occurs at much higher strain values that in osteoporotic bone. After the fracture a normal trabecular architecture is able to carry much higher loads than an osteoporotic architecture. However, no statistically significant differences were found in maximal stress during uniaxial compression of the central part of normal, osteoporotic, and extreme osteoporotic vertebral trabecular bone. This supports the hypothesis that osteoporotic trabecular bone can compensate for a loss of trabeculae by thickening the remaining trabeculae in the loading direction (compensatory hypertrophy). The developed approach could be used for mechanical evaluation of structural data acquired non-invasively and assessment of changes in performance of bone architecture.

Purpose: Percutaneous vertebroplasty (PV) is a minimally invasive procedure involving the injection of bone cement within a collapsed vertebral body. Although this procedure was demonstrated to be effective in osteoporosis and metastases, few studies have been reported in cases of multiple myeloma (MM). We prospectively evaluated the safety and efficacy of PV in the treatment of vertebral compression fractures (VCFs) resulting from MM. Materials and Methods: PV was performed in 106 consecutive MM patients who had back pain due to VCFs, the treatment of which had failed conservative therapies. Follow-up (28.2 {+-} 12.1 months) was evaluated at 7 and 15more » days as well as at 1, 3, 6, 12, 18, and every 6 months after PV. Visual analog scale (VAS) pain score, opioid use, external brace support, and Oswestry Disability Index (ODI) score were recorded. Results: The median pretreatment VAS score of 9 (range 4-10) significantly (P < 0.001) decreased to 1 (range 0-9) after PV. Median pre-ODI values of 82% (range 36-89%) significantly improved to 7% (range 0-82%) (P < 0.001). Differences in pretreatment and posttreatment use of analgesic drug were statistically significant (P < 0.001). The majority of patients (70 of 81; 86%) did not use an external brace after PV (P < 0.001). Conclusion: PV is a safe, effective, and long-lasting procedure for the treatment of vertebral compression pain resulting from MM.« less

Case series. To report our early experience of percutaneous vertebro-plasty via a transoral approach of the lesions of the lateral mass of C1. Percutaneous vertebroplasty has gained acceptance for the treatment of osteolytic lesions of the spine. However, scant data are available on the percutaneous vertebroplasty of the C1 lesions. Two patients (a 74-yr-old female and a 53-yr-old male) presenting respectively a metastasis of the left lateral mass of C1 from a pancreatic adenocarcinoma and a hemangioma of the left lateral mass of C1 underwent a percutaneous vertebroplasty via a transoral approach in a hybrid angio suite associating a monoplane flat panel and a computed tomography scan, using polymethylmetacrilate bone cement.For the second patient, a nondetachable balloon was used to protect the vertebral artery from cement leakage. Satisfactory filing of the lesions was obtained in both patients. No complication was recorded. Both patients experienced pain improvement. Transoral approach for the treatment of osteolytic tumor lesions of the lateral mass of the atlas is feasible and seems to be a safe and effective technique.

To calculate and compare combined axial and flexural stresses in lordosis versus buckled configurations of the sagittal cervical curve. Digitized measurements from lateral cervical radiographs of four different shapes were used to calculate axial loads and bending moments on the vertebral bodies of C2-C7.Background. Osteoarthritis and spinal degeneration are factors in neck and back pain. Calculations of stress in clinically occurring configurations of the sagittal cervical spine are rare. Center of gravity of the head (inferior-posterior sella turcica) and vertebral body margins were digitized on four different lateral cervical radiographs: lordosis, kyphosis, and two "S"-shapes. Polynomials (seventh degree) and stress concentrations on the concave and convex margins were derived for the shape of the sagittal cervical curvatures from C1 to T1. Moments of inertia were determined from digitizing and the use of an elliptical shell model of cross-section. Moment arms from a vertical line through the center of gravity of the head to the atlas and scaled neck extensor moment arms from the literature were used to compute the vertical component of extensor muscle effort. Segmental lever arms were calculated from a vertical line through C1 to each vertebra. In lordosis, anterior and posterior stresses in the vertebral body are nearly uniform and minimal. In kyphotic areas, combined stresses changed from tension to compression at the anterior vertebral margins and were very large (6-10 times as large in magnitude) compared to lordosis. In kyphotic areas at the posterior vertebral body, the combined stresses changed from compression (in lordosis) to tension. The stresses in kyphotic areas are very large and opposite in direction compared to a normal lordosis. This analysis provides the basis for the formation of osteophytes (Wolff's Law) on the anterior margins of vertebrae in kyphotic regions of the sagittal cervical curve. This indicates that any kyphosis is an undesirable configuration in the cervical spine. Relevance. Osteophytes and osteoarthritis are found at areas of altered stress and strain. Axial and flexural stresses at kyphotic areas in the sagittal cervical spine are abnormally high.

High-resolution imaging and biomechanical investigation of ex-vivo vertebrae. The aim of this study was to assess bone microarchitecture of cadaveric vertebrae using ultra-high field (UHF) 7 Tesla magnetic resonance imaging (MRI) and to determine whether the corresponding microarchitecture parameters were related to bone mineral density (BMD) and bone strength assessed by dual-energy x-ray absorptiometry (DXA) and mechanical compression tests. Limitations of DXA for the assessment of bone fragility and osteoporosis have been recognized and criteria of microarchitecture alteration have been included in the definition of osteoporosis. Although vertebral fracture is the most common osteoporotic fracture, no study has assessed directly vertebral trabecular bone microarchitecture. BMD of 24 vertebrae (L2, L3, L4) from eight cadavers was investigated using DXA. The bone volume fraction (BVF), trabecular thickness (Tb.Th), and trabecular spacing (Tb.Sp) of each vertebra were quantified using UHF MRI. Measurements were performed by two operators to characterize the inter-rater reliability. The whole set of specimens underwent mechanical compression tests to failure and the corresponding failure stress was calculated. The inter-rater reliability for bone microarchitecture parameters was good with intraclass correlation coefficients ranging from 0.82 to 0.94. Failure load and stress were significantly correlated with BVF, Tb.Sp, and BMD (P < 0.05). Tb.Th was only correlated with the failure stress (P < 0.05). Multiple regression analysis demonstrated that the combination of BVF and BMD improved the prediction of the failure stress from an adjusted R = 0.384 for BMD alone to an adjusted R = 0.414. We demonstrated for the first time that the vertebral bone microarchitecture assessed with UHF MRI was significantly correlated with biomechanical parameters. Our data suggest that the multimodal assessment of BMD and trabecular bone microarchitecture with UHF MRI provides additional information on the risk of vertebral bone fracture and might be of interest for the future investigation of selected osteoporotic patients.

Vertebral fracture (or vertebral deformity) is a very common outcome of osteoporosis, which is one of the major public health concerns in the world. Early detection of vertebral fractures is important because timely pharmacologic intervention can reduce the risk of subsequent additional fractures. Chest radiographs are used routinely for detection of lung and heart diseases, and vertebral fractures can be visible on lateral chest radiographs. However, investigators noted that about 50% of vertebral fractures visible on lateral chest radiographs were underdiagnosed or under-reported, even when the fractures were severe. Therefore, our goal was to develop a computerized method for detectionmore » of vertebral fractures on lateral chest radiographs in order to assist radiologists' image interpretation and thus allow the early diagnosis of osteoporosis. The cases used in this study were 20 patients with severe vertebral fractures and 118 patients without fractures, as confirmed by the consensus of two radiologists. Radiologists identified the locations of fractured vertebrae, and they provided morphometric data on the vertebral shape for evaluation of the accuracy of detecting vertebral end plates by computer. In our computerized method, a curved search area, which included a number of vertebral end plates, was first extracted automatically, and was straightened so that vertebral end plates became oriented horizontally. Edge candidates were enhanced by use of a horizontal line-enhancement filter in the straightened image, and a multiple thresholding technique, followed by feature analysis, was used for identification of the vertebral end plates. The height of each vertebra was determined from locations of identified vertebral end plates, and fractured vertebrae were detected by comparison of the measured vertebral height with the expected height. The sensitivity of our computerized method for detection of fracture cases was 95% (19/20), with 1.03 (139/135) false-positive fractures per image. The accuracy of identifying vertebral end plates, marked by radiologists in a morphometric study, was 76.6% (400/522) and 70.9% (420/592) for cases used for training and those for testing, respectively. We prepared 32 additional fracture cases for a validation test, and we examined the detection accuracy of our computerized method. The sensitivity for these cases was 75% (24/32) at 1.03 (33/32) false-positive fractures per image. Our preliminary results show that the automated computerized scheme for detecting vertebral fractures on lateral chest radiographs has the potential to assist radiologists in detecting vertebral fractures.« less

To investigate the clinical feature of the chronic compressive optic neuropathy without optic atrophy. Retrospective cases series study. The clinical data of 25 patients (37 eyes) with chronic compressive optic neuropathy without optic atrophy, treated in Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, from October, 2005 to March, 2014, were collected. Those patients had been showing visual symptoms for 6 months or longer, but missed diagnosed or misdiagnosed as other eye diseases due to their normal or slightly changed fundi. The collected data including visual acuities, visual fields, neuroimaging and/or pathologic diagnosis were analyzed. Among the 25 patients, there were 5 males and 20 females, and their ages range from 9 to 74 years [average (47.5 ± 13.4) years]. All patients suffered progressive impaired vision in single eye or both eyes, without exophthalmos or abnormal eye movements. Except one patient had a headache, other patients did not show systemic symptoms. The corrected visual acuities were between HM to 1.0, and their appearances of optic discs and colors of fundi were normal. After neuroimaging and/or pathological examination, it was proven that 14 patients suffered tuberculum sellae meningiomas, 5 patients with hypophysoma, 3 patient with optic nerve sheath meningioma in orbital apex, 1 patient with cavernous hemangioma, 1 patient with vascular malformation in orbital apex and 1 patient with optic nerve glioma. Among the 19 patients whose suffered occupied lesions of saddle area, 14 patients underwent visual field examinations, and only 4 patients showed classic visual field defects caused by optic chiasmal lesions. Occult progressive visual loss was the most important clinical feature of the disease.

Combined pituitary hormone deficiency (CPHD) refers to a rare heterogeneous group of conditions in which there is a deficiency in at least two anterior pituitary hormones. Patients with POU1F1 mutations show a combined pituitary deficiency with low or absent levels of growth hormone, prolactin, and thyroid-stimulating hormone. In this study, a 7-month-old girl with a CPHD is presented. She had facial dysmorphologic features, hypertrichosis, and hypotonia. Additionally, she also presented with multiple cutaneous hemangioma that until now has not been reported in association with this disorder.

Cavernous hemangioma is the most common orbital tumor in adult. There is lot of literatures for clinicopathological features of this tumor. These tumors had been studied for the model of angiogenesis in many of the experimental setups. We present a case of 34-year-old male with this tumor in the left eye with computerized tomography evidence. Postsurgical laboratory findings gave interesting evidence of tumor angiogenesis with tumor endothelial cells and sprouting of the small vessels endothelial cells. Podosome rosette could be conceptualized from the characteristic patterns seen in the tumor.

Purpose: Vertebral hemangiomas (VHs) are the most common benign tumors of the spine that may cause bone resorption. Megavoltage irradiation is usually the treatment of choice for the management of symptomatic VHs. The current study was conducted to estimate the risk for carcinogenesis from radiotherapy of this benign disease on the basis of the calculated radiation doses to healthy organs. Methods: The Monte Carlo N-particle transport code was employed to simulate the irradiation with 6 MV x-rays of a VH presented in the cervical, upper thoracic, lower thoracic, and lumbar spine. The average radiation dose (D{sub av}) received by eachmore » critical organ located outside the primarily irradiated area was calculated. Three-dimensional treatment plans were also generated for the VHs occurring at the four different sites of the spinal cord based on patients’ computed tomography data. The organ equivalent dose (OED) to each radiosensitive structure, which was partly encompassed by the applied treatment fields, was calculated with the aid of differential dose–volume histograms. The D{sub av} and the OED values were combined with a linear-no-threshold model and a nonlinear mechanistic model, respectively, to estimate the organ-, age-, and gender-specific lifetime attributable risks (LARs) for cancer development. The estimated risks were compared with the respective nominal lifetime intrinsic risks (LIRs) for the unexposed population. Results: For a standard target dose of 34 Gy, the OED varied from 0.39–5.15 Gy by the organ of interest and the irradiation site. The D{sub av} range for the out-of-field organs was 4.9 × 10{sup −4} to 0.56 Gy. The LAR for the appearance of malignancies in the partially in-field organs after radiotherapy of male and female patients was (0.08%–1.8%) and (0.09%–1.9%), respectively. These risk values were 1.5–15.5 times lower when compared to the respective LIRs. The lifetime probability for out-of-field cancer induction in irradiated males and females was (2.5 × 10{sup −4} to 7.7 × 10{sup −2})% and (1.4 × 10{sup −4} to 2.6 × 10{sup −1})%, respectively. The above risks were one to four orders of magnitude lower than the LIRs. Conclusions: The probability for the development of out-of-field malignancies due to radiotherapy for VHs is trivial with respect to the nominal risk for unexposed population. The respective cancer risks to partially in-field organs are smaller than the nominal probabilities but they should not be considered as inconsiderable. These risks may be taken into account during the follow-up of patients treated for a symptomatic VH.« less

OBJECTIVE: To examine treatment indications, efficacy and side effects of oral beta-blockers for the treatment of problematic hemangiomas. METHODS: A retrospective review of patients with hemangiomas presenting to the Alberta Children’s Hospital Vascular Birthmark Clinic (Calgary, Alberta) between 2009 and 2011 was conducted. The subset of patients treated with oral beta-blockers was further characterized, investigating indication for treatment, response to treatment, time to resolution of indication, duration of treatment, occurrence of rebound growth and side effects of therapy. RESULTS: Between 2009 and 2011, 311 new patients with hemangiomas were seen, of whom 105 were treated with oral beta-blockers. Forty-five patients completed beta-blocker treatment while the remainder continue to receive therapy. Indications for treatment were either functional concerns (68.6%) or disfigurement (31.4%). Functional concerns included ulceration (29.5%), periocular location with potential for visual interference (28.6%), airway interference (4.8%), PHACES syndrome (3.8%), auditory interference (0.95%) and visceral location with congestive heart failure (0.95%). The median age at beta-blocker initiation was 3.3 months; median duration of therapy was 10.6 months; and median maximal treatment dose was 1.5 mg/kg/day for propranolol and 1.6 mg/kg/day for atenolol. Ninety-nine patients (94.3%) responded to therapy with size reduction, colour changes, softened texture and/or healing of ulceration. Rebound growth requiring an additional course of therapy was observed in 23 patients. Side effects from beta-blockers included cool extremities (26.7%), irritability (17.1%), lower gastrointestinal upset (14.3%), emesis (11.4%), hypotension (10.5%), poor feeding (7.6%), lethargy (4.8%), bronchospasm (0.95%) and rash (0.95%). Side effects did not result in complete discontinuation of beta-blocker treatment in any case; however, they prompted a switch to a different beta-blocker preparation in some cases. Resolution of the primary indication, requiring a median time of three months, occurred in 87 individuals (82.9%). CONCLUSIONS: Treatment of infantile hemangiomas with oral beta-blocker therapy is highly effective and well tolerated, with more than 94% of patients demonstrating a response to treatment and 90% showing resolution of the primary functional indication for treatment.

Hemangioma stem cells (HemSCs) are multipotent cells isolated from infantile hemangioma (IH), which form hemangioma-like lesions when injected subcutaneously into immune-deficient mice. In this murine model, HemSCs are the primary target of corticosteroid, a mainstay therapy for problematic IH. The relationship between HemSCs and endothelial cells that reside in IH is not clearly understood. Adhesive interactions might be critical for the preferential accumulation of HemSCs and/or endothelial cells in the tumor. Therefore, we studied the interactions between HemSCs and endothelial cells (HemECs) isolated from IH surgical specimens. We found that HemECs isolated from proliferating phase IH, but not involuting phase, constitutively express E-selectin, a cell adhesion molecule not present in quiescent endothelial cells. E-selectin was further increased when HemECs were exposed to vascular endothelial growth factor–A or tumor necrosis factor–α. In vitro, HemSC migration and adhesion was enhanced by recombinant E-selectin but not P-selectin; both processes were neutralized by E-selectin–blocking antibodies. E-selectin–positive HemECs also stimulated migration and adhesion of HemSCs. In vivo, neutralizing antibodies to E-selectin strongly inhibited formation of blood vessels when HemSCs and HemECs were co-implanted in Matrigel. These data suggest that endothelial E-selectin could be a major ligand for HemSCs and thereby promote cellular interactions and vasculogenesis in IH. We propose that constitutively expressed E-selectin on endothelial cells in the proliferating phase is one mediator of the stem cell tropism in IH. PMID:23041613

The aim was to compare high-resolution computed tomography (HRCT) and thin-section magnetic resonance imaging (MRI) findings of facial nerve hemangioma. The HRCT and MRI characteristics of 17 facial nerve hemangiomas diagnosed between 2006 and 2013 were retrospectively analyzed. All patients included in the study suffered from a space-occupying lesion of soft tissues at the geniculate ganglion fossa. Affected nerve was compared for size and shape with the contralateral unaffected nerve. HRCT showed irregular expansion and broadening of the facial nerve canal, damage of the bone wall and destruction of adjacent bone, with "point"-like or "needle"-like calcifications in 14 cases. The average CT value was 320.9 ± 141.8 Hu. Fourteen patients had a widened labyrinthine segment; 6/17 had a tympanic segment widening; 2/17 had a greater superficial petrosal nerve canal involvement, and 2/17 had an affected internal auditory canal (IAC) segment. On MRI, all lesions were significantly enhanced due to high blood supply. Using 2D FSE T2WI, the lesion detection rate was 82.4 % (14/17). 3D fast imaging employing steady-state acquisition (3D FIESTA) revealed the lesions in all patients. HRCT showed that the average number of involved segments in the facial nerve canal was 2.41, while MRI revealed an average of 2.70 segments (P < 0.05). HRCT and MR findings of facial nerve hemangioma were typical, revealing irregular masses growing along the facial nerve canal, with calcifications and rich blood supply. Thin-section enhanced MRI was more accurate in lesion detection and assessment compared with HRCT.
Diagnosis and Treatment of Bone Disease in Multiple Myeloma: Spotlight on Spinal Involvement
Tosi, Patrizia
2013-01-01
Bone disease is observed in almost 80% of newly diagnosed symptomatic multiple myeloma patients, and spine is the bone site that is more frequently affected by myeloma-induced osteoporosis, osteolyses, or compression fractures. In almost 20% of the cases, spinal cord compression may occur; diagnosis and treatment must be carried out rapidly in order to avoid a permanent sensitive or motor defect. Although whole body skeletal X-ray is considered mandatory for multiple myeloma staging, magnetic resonance imaging is presently considered the most appropriate diagnostic technique for the evaluation of vertebral alterations, as it allows to detect not only the exact morphology of the lesions, but also the pattern of bone marrow infiltration by the disease. Multiple treatment modalities can be used to manage multiple myeloma-related vertebral lesions. Surgery or radiotherapy is mainly employed in case of spinal cord compression, impending fractures, or intractable pain. Percutaneous vertebroplasty or balloon kyphoplasty can reduce local pain in a significant fraction of treated patients, without interfering with subsequent therapeutic programs. Systemic antimyeloma therapy with conventional chemotherapy or, more appropriately, with combinations of conventional chemotherapy and compounds acting on both neoplastic plasma cells and bone marrow microenvironment must be soon initiated in order to reduce bone resorption and, possibly, promote bone formation. Bisphosphonates should also be used in combination with antimyeloma therapy as they reduce bone resorption and prolong patients survival. A multidisciplinary approach is thus needed in order to properly manage spinal involvement in multiple myeloma. PMID:24381787

Hemifacial spasm (HFS) is caused by arterial or venous compression of cranial nerve VII at its root exit zone. Traditionally, microvascular decompression of the facial nerve has been an effective treatment for posterior inferior and anterior inferior cerebellar artery as well as venous compression. The traditional technique involves Teflon felt or another construct to cushion the offending vessel from the facial nerve, or cautery and division of the offending vein. However, using this technique for severe vertebral artery (VA) compression can be ineffective and fraught with complications. The authors report the use of a new technique of VA pexy to the petrous or clival dura mater in patients with HFS attributed to a severely ectatic and tortuous VA, and detail the results in a series of patients. Six patients with HFS due to VA compression underwent a retrosigmoid craniotomy, combined with a far-lateral approach in some patients. On identification of the site of VA compression, the vessel was mobilized adequately for the decompression. Great care was taken to avoid kinking the perforating vessels arising from the VA. Two 8-0 nylon sutures were passed through to the wall of the VA and then through the clival or petrous dura, and then tied to alleviate compression on cranial nerve VII. Patients were followed for at least 1 year postoperatively (mean 2.7 years, range 1-4 years). All 6 patients had complete resolution of their HFS. Facial function was tested postoperatively, and was stable when compared with the preoperative baseline. Two of the 3 patients with preoperative tinnitus had resolution of this symptom after the procedure. Postoperative imaging demonstrated VA decompression of the facial nerve and no evidence of stroke in all patients. One patient suffered from hearing loss, another developed a postoperative transient unilateral vocal cord paralysis, and a third patient developed a pseudomeningocele that resolved with the placement of a lumbar drain. Hemifacial spasm and other neurovascular syndromes are effectively treated by repositioning the compressing artery. Careful study of the preoperative MR images may identify a select group of patients with HFS due to an ectatic VA. Rather than traditional decompression with only pledget placement, these patients may benefit from a VA pexy to provide an effective, safe, and durable resolution of their symptoms while minimizing surgical complications.
Nasal glial heterotopia or congenital hemangioma? A case report.
Lartizien, R; Durand, C; Blaise, S; Morand, B
2017-10-01
Nasal glial heterotopia (NGH) is a rare benign tumor of the median line. We describe the case of a child presenting a lateral nasal mass. The characteristics of the prenatal ultrasound and the postnatal clinical examination argued in favor of a congenital hemangioma (CH). The MRI performed at 6 weeks of life suggested glial heterotopia. This diagnosis was confirmed by the pathological analysis. Congenital hemangiomas and nasal glial heterotopies have similar clinical presentations. Prenatal ultrasound diagnosis between NGH and CH is difficult. Fetal MRI is not yet highly specific for these two lesions, but it can eliminate an intracerebral connection in cases of NGH. Postnatal exams are more specific. Flow on the Doppler exam is rapid for CH and slow for NGH. On MRI, these two lesions appear as a hypersignal on T2-weighted sequences, but less intense for NGH than for CH. Distinguishing between NGH and CH can be difficult. This does not have a direct incidence on treatment because it is surgical in both cases. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

It has been well-known that technetium-99m-human serum albumin-diethylenetriaminepenta-acetic acid (99mTc-HSAD) scintigraphy is useful for diagnosis of the localization of the gastrointestinal arterial or venous bleeding. In this report, we describe a case of venous bleeding from capillary hemangioma of the ileum end detected by 99mTc-HSAD scintigraphy. This patient was a 9-year-old girl with severe anemia. Gastrointestinal bleeding was suspected from her clinical course and laboratory tests. Immediately after melena occurred, 99mTc-HSAD scintigraphy showed the extravasation of RI suggesting gastrointestinal bleeding in the ileum end. Abdominal angiography immediately after 99mTc-HSAD scintigraphy, however, could not show the extravasation of contrast agent. Because the condition of the patient became worse, laparotomy was performed on the basis of 99mTc-HSAD scintigraphy findings. At surgery, venous bleeding from capillary hemangioma in the ileum end was observed. It was suggested that 99mTc-HSAD scintigraphy was very useful for identifying the gastrointestinal venous bleeding.

Voluminous vascular anomalies of the head and neck region are still treated with conventional surgery although Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser therapy is an effective treatment method. One hundred thirty give patients with voluminous hemangiomas and vascular malformations were treated with interstitial Nd:YAG laser therapy, partly complemented by a non-contact mode Nd:YAG laser light application. The vascular tumors had a diameter of more than 3 cm in two or all three dimensions. Treatment was carried out under ultrasound and manual control. Nearly 60% of the patients showed a complete clinical regression of the vascular tumor, a third of the patients had a partial regression and were satisfied with the treatment outcome. Four patients were treated unsuccessfully with the laser and three of them subsequently underwent conventional surgery. Only 10 patients showed cosmetic and functional deficits. These results on the interstitial Nd:YAG laser therapy of voluminous hemangiomas and vascular malformations in a large patient group demonstrated the high effectiveness of this novel and innovative therapy modality.
Simple Preparation of Timolol 0.5% Gel from Eye Drop Solution for Superficial Infantile Hemangiomas.
Choo, Winnie
2017-01-01
The discovery of beta-adrenergic blocker effects on infantile hemangiomas has affected the choice of treatment in recent years. Oral propranolol is effective in treating infantile hemangiomas, but the risk of systemic side effects remains a concern. Data from literature review reported positive clinical outcomes with no major adverse effects observed in children using topical beta-blocker such as timolol maleate. Topical application of timolol eye drop has been mentioned in few studies, most of which reported that the solution cannot stay on the site of application due to its fluidity. Adding hydroxyethyl cellulose into a timolol solution increased its viscosity by forming a hydrogel and thus changed the rheology property. The compounded timolol gel exhibited thixotropy property allowing better and longer contact at sites of application. Experimental data from literature review showed desirable characteristics and measurable flux of timolol across human stratum corneum. Gel dosage form allows easy and precise application and maximizes timolol's therapeutic efficacy at the sites of application. Copyright© by International Journal of Pharmaceutical Compounding, Inc.

A recent fieldwork in the Kağızman-Tuzluca Basin in northeastern Turkey led us to the discovery of three vertebrate localities which yielded some limb bones of the giant rhino Paraceratherium, a crocodile tooth, and some small mammals, respectively. These discoveries allowed, for the first time to date some parts of the sedimentary units of this basin. This study also shows that the dispersal area of Paraceratherium is wider than it was known before. Eastern Turkey has several Cenozoic sedimentary basins formed during the collision of the Arabian and Eurasian plates. They are poorly documented for vertebrate paleontology. Consequently, the timing of tectonic activities, which led to the formation of the East Anatolian accretionary complex, is not constrained enough with a solid chronological framework. This study provides the first biostratigraphic evidences for the infill under the control of the compressive tectonic regime, which built the East Anatolian Plateau.

Patients with osteoporotic vertebral compression fracture (OVCF) have postural changes and increased risk of falling. The aim of this study is to compare balance characteristics between patients with OVCF and healthy control subjects. Patients with severe OVCF and control subjects underwent computerised dynamic posturography (CDP) in this case-control study. Forty-seven OVCF patients and 45 controls were recruited. Compared with the control group, the OVCF group had significantly decreased average stability; maximal stability under the `eye open with swayed support surface' (CDP subtest 4) and 'eye closed with swayed support surface' conditions (subtest 5); and decreased ankle strategy during subtests 4 and 5 and under the `swayed vision with swayed support surface' condition (subtest 6). The OVCF group fell more frequently during subtests 5 and 6 and had longer overall reaction time and longer reaction time when moving backward during the directional control test. OVCF patients had poorer static and dynamic balance performance compared with normal control. They had decreased postural stability and ankle strategy with increased fall frequency on a swayed surface; they also had longer reaction times overall and in the backward direction. Therefore, we suggest balance rehabilitation for patients with OVCF to prevent fall.

The aim of this clinical study was to report on the efficacy in reduction and safety in PMMA leakage of a novel vertebral augmentation technique with PEEK and PMMA, together with pedicle screws in the treatment of fresh vertebral fractures in young adults. Twenty consecutive young adults aged 45 ± 11 years with fresh burst A3/AO or severely compressed A2/AO fractures underwent via a less invasive posterior approach one-staged reduction with a novel augmentation implant and PMMA plus 3-vertebrae pedicle screw fixation and fusion. Radiologic parameters as segmental kyphosis (SKA), anterior (AVBHr) and posterior vertebral body height ratio (PVBHr), spinal canal encroachment (SCE), cement leakage and functional parameters as VAS, SF-36 were measured pre- and post-operatively. Hybrid construct restored AVBHr (P < 0.000), PVBHr (P = 0.02), SKA (P = 0.015), SCE (P = 0.002) without loss of correction at an average follow-up of 17 months. PMMA leakage occurred in 3 patients (3 vertebrae) either anteriorly to the fractured vertebral body or to the adjacent disc, but in no case to the spinal canal. Two pedicle screws were malpositioned (one medially, one laterally to the pedicle at the fracture level) without neurologic sequelae. Solid posterolateral spinal fusion occurred 8-10 months post-operatively. Pre-operative VAS and SF-36 scores improved post-operatively significantly. This study showed that this novel vertebral augmentation technique using PEEK implant and PMMA reduces and stabilizes via less invasive technique A2 and A3 vertebral fractures without loss of correction and leakage to the spinal canal.

An exact understanding of patient vertebral artery anatomy is essential to safely place screws at the atlanto-axial level in posterior arthrodesis. We aim to report a case of erosion of the left vertebral artery into the C1-C2 facet complex with resultant rotatory and lateral listhesis presenting with severe occipital headache. This represents a novel etiology for this diagnosis and our report illustrates technical considerations when instrumenting the C1-C2 segment. We report a case of severe occipital headache due to C1-C2 instability with resultant left C2 nerve compression in the setting of erosion of the vertebral artery into the C1-C2 facet complex. A 68-year-old woman presented with a 12-month history of progressively debilitating headache and neck pain with atlanto-axial instability. Computed tomography (CT) angiography demonstrated erosion of the left vertebral artery into the left C1-C2 facet complex. In addition, the tortuous vertebral arteries had eroded into the C2 pedicles, eliminating the possibility for posterior pedicle screw placement. The patient underwent posterior arthrodesis of C1-C2 utilizing bilateral lateral mass fixation into C1 and bilateral trans-laminar fixation into C2 with resolution of all preoperative complaints. This study constitutes the first report of a tortuous vertebral artery causing the partial destruction of a C1-C2 facet complex, as well as instability, with the clinical presentation of severe occipital headache. It hereby presents a novel etiology for both the development of C1-C2 segment instability as well as the development of occipital headache. Careful evaluation of such lesions utilizing CT angiography is important when formulating a surgical plan.

Radiation-induced internal carotid artery occlusion has not been well recognized previously as a cause of childhood cerebrovascular disease. A child who had received radiation as a neonate for a hemangioma involving the left orbit at the age of 6 years experienced a recurrent right-sided paresis, vascular headaches, and speech difficulties. Angiography showed a hypoplastic left carotid artery with occlusion of both the anterior and middle cerebral arteries. Collateral vessels bypassed the occluded-stenotic segments. Review of the literature showed two additional cases of large vessel occlusion in childhood associated with anastomatic telangiectatic vessel development following early radiation therapy of facial hemangioma.

Maffucci's syndrome is a congenital, non-hereditary mesodermal dysplasia associated with multiple enchondromas and after some years accompanied by hemangiomas. We describe a rare case of "reverse" Maffucci's syndrome in a 42-year-old woman who has suffered from multiple hemangiomas for the last 24 years. The last two years she complained for heel pain. Bone scintigraphic examination showed abnormal findings in the left calcaneal bone. The scintigraphy, radiology and histology findings revealed multiple enchondromas, so the diagnosis was changed into Maffucci's syndrome. After one year, the left calcaneal bone showed sarcomatous transformation.

A 16-year-old boy presented with multiple posterior circulation ischemic strokes resulting from vertebral artery (VA) dissection. Three-dimensional computed tomography showed aberrant sub-occipital bone protuberance, proximal to the VA dissection. Since the patient was a habitual neck cracker, VA dissection was thought to result from the impact shock of the rotational head movement. This could be due to either the osseous prominence or the compression between the prominence and the C1. Although it is a rare etiology of Bow Hunter's syndrome, VA dissection due to sub-occipital bone spur because of neck cracking should be considered in the diagnosis of Bow Hunter's syndrome in juvenile patients.
Double Aortic Arch With Previously Undescribed Head and Neck Vessel Branching.

Vascular ring in the form of a double aortic arch is a rare anomaly that can cause airway compression. It occasionally occurs with unusual head and neck vessel branching. A 5-year-old boy with chronic respiratory symptoms was referred because of a tracheal indentation on his chest x-ray. Magnetic resonance imaging showed a double aortic arch with arch origins of a common carotid, vertebral, and subclavian on the right and internal and external carotids, vertebral, and subclavian arteries on the left. Our case represents, to our knowledge, the first report of a double aortic arch with 7 separate vessels arising from the transverse arches. Copyright © 2016 Canadian Cardiovascular Society.

Hemangioma stem cells (HemSCs) are multipotent cells isolated from infantile hemangioma (IH), which form hemangioma-like lesions when injected subcutaneously into immune-deficient mice. In this murine model, HemSCs are the primary target of corticosteroid, a mainstay therapy for problematic IH. The relationship between HemSCs and endothelial cells that reside in IH is not clearly understood. Adhesive interactions might be critical for the preferential accumulation of HemSCs and/or endothelial cells in the tumor. Therefore, we studied the interactions between HemSCs and endothelial cells (HemECs) isolated from IH surgical specimens. We found that HemECs isolated from proliferating phase IH, but not involuting phase, constitutively express E-selectin, a cell adhesion molecule not present in quiescent endothelial cells. E-selectin was further increased when HemECs were exposed to vascular endothelial growth factor-A or tumor necrosis factor-α. In vitro, HemSC migration and adhesion was enhanced by recombinant E-selectin but not P-selectin; both processes were neutralized by E-selectin-blocking antibodies. E-selectin-positive HemECs also stimulated migration and adhesion of HemSCs. In vivo, neutralizing antibodies to E-selectin strongly inhibited formation of blood vessels when HemSCs and HemECs were co-implanted in Matrigel. These data suggest that endothelial E-selectin could be a major ligand for HemSCs and thereby promote cellular interactions and vasculogenesis in IH. We propose that constitutively expressed E-selectin on endothelial cells in the proliferating phase is one mediator of the stem cell tropism in IH.

Infantile hemangiomas (IHs) are common neoplasms composed of proliferating endothelial-like cells. Despite the relative frequency of IH and the potential severity of complications, there are currently no uniform guidelines for treatment. Although propranolol has rapidly been adopted, there is significant uncertainty and divergence of opinion regarding safety monitoring, dose escalation, and its use in PHACE syndrome (PHACE = posterior fossa, hemangioma, arterial lesions, cardiac abnormalities, eye abnormalities; a cutaneous neurovascular syndrome characterized by large, segmental hemangiomas of the head and neck along with congenital anomalies of the brain, heart, eyes and/or chest wall). A consensus conference was held on December 9, 2011. The multidisciplinary team reviewed existing data on the pharmacologic properties of propranolol and all published reports pertaining to the use of propranolol in pediatric patients. Workgroups were assigned specific topics to propose protocols on the following subjects: contraindications, special populations, pretreatment evaluation, dose escalation, and monitoring. Consensus protocols were recorded during the meeting and refined after the meeting. When appropriate, protocol clarifications and revision were made and agreed upon by the group via teleconference. Because of the absence of high-quality clinical research data, evidence-based recommendations are not possible at present. However, the team agreed on a number of recommendations that arose from a review of existing evidence, including when to treat complicated IH; contraindications and pretreatment evaluation protocols; propranolol use in PHACE syndrome; formulation, target dose, and frequency of propranolol; initiation of propranolol in infants; cardiovascular monitoring; ongoing monitoring; and prevention of hypoglycemia. Where there was considerable controversy, the more conservative approach was selected. We acknowledge that the recommendations are conservative in nature and anticipate that they will be revised as more data are made available. PMID:23266923

Bilateral Renal Anastomosing Hemangiomas: A Tale of Two Kidneys
Abboudi, Hamid; Tschobotko, Benjamin; Carr, Christopher
2017-01-01
Abstract Background: Renal anastomosing hemangioma (RAH) is an extremely rare benign vascular tumor first described in 2009. Making this diagnosis is fraught with challenges. Radiologically they share features consistent with renal cell carcinomas (RCCs). Their vascular nature poses risks if considering preoperative biopsy and histologically they share characteristics akin to angiosarcomas. The few reports published in the literature suggest presentation with hematuria, flank pain, and polycythemia although the majority are diagnosed at postnephrectomy histologic examination. This case represents the first metachronous RAH in the literature, and is the first RAH presenting with severe hemorrhage. Case Presentation: A 62-year-old woman of Albanian heritage presented to urology with visible hematuria and positive urine cytology. Three years before this presentation, she had undergone an elective radical right-sided nephrectomy for a suspected RCC detected on magnetic resonance imaging, which proved to be an RAH after postoperative histologic examination of the specimen. The patient was investigated with cystoscopy and ureteroscopy for this new hematuria presentation, both of which were unremarkable. Fourteen hours post ureteroscopy, the patient became severely hypotensive and developed acute kidney injury. A CT scan indicated a large left-sided renal subcapsular and retroperitoneal hematoma that was actively bleeding. The patient was hemodynamically unstable and, therefore, required an emergency open left-sided nephrectomy, rendering her anephric and dialysis dependent. Postoperative histologic examination proved that the left kidney also contained an RAH. Conclusion: The anastomosing hemangioma is an important subtype to differentiate from angiosarcoma before and after a nephrectomy. Urologists should carefully consider invasive tests in patients with previously diagnosed vascular lesions as there may be an increased risk of bleeding. Patients with a previously diagnosed anastomosing hemangioma may require surveillance of the contralateral kidney. PMID:29279869

A novel biodegradable copolymer, poly(propylene fumarate-co-caprolactone) [P(PF-co-CL)], has been developed in our laboratory as an injectable scaffold for bone defect repair. In the current study, we evaluated the ability of P(PF-co-CL) to reconstitute the load-bearing capacity of vertebral bodies with lytic lesions. Forty vertebral bodies from four fresh-frozen cadaveric thoracolumbar spines were used for this study. They were randomly divided into four groups: intact vertebral body (intact control), simulated defect without treatment (negative control), defect treated with P(PF-co-CL) (copolymer group), and defect treated with poly(methyl methacrylate) (PMMA group). Simulated metastatic lytic defects were made by removing a central core of the trabecular bone in each vertebral body with an approximate volume of 25% through an access hole in the side of the vertebrae. Defects were then filled by injecting either P(PF-co-CL) or PMMA in situ crosslinkable formulations. After the spines were imaged with quantitative computerized tomography, single vertebral body segments were harvested for mechanical testing. Specimens were compressed until failure or to 25% reduction in body height and ultimate strength and elastic modulus of each specimen were then calculated from the force–displacement data. The average failure strength of the copolymer group was 1.83 times stronger than the untreated negative group and it closely matched the intact vertebral bodies (intact control). The PMMA-treated vertebrae, however, had a failure strength 1.64 times larger compared with the intact control. The elastic modulus followed the same trend. This modulus mismatch between PMMA-treated vertebrae and the host vertebrae could potentially induce a fracture cascade and degenerative changes in adjacent intervertebral discs. In contrast, P(PF-co-CL) restored the mechanical properties of the treated segments similar to the normal, intact, vertebrae. Therefore, P(PF-co-CL) may be a suitable alternative to PMMA for vertebroplasty treatment of vertebral bodies with lytic defects. PMID:24256208

Dynamic radiographs are recommended to investigate non-healing evidence such as the dynamic mobility or intravertebral clefts in osteoporotic vertebral compression fractures (VCFs). However, it is difficult to examine standing flexion and extension lateral radiographs due to severe pain. The use of prone cross-table lateral radiographs (PrLRs) as a diagnostic tool has never been proposed to our knowledge. The purpose of this study is to clarify the usefulness of PrLRs in diagnosis and treatment of VCFs. We reviewed 62 VCF patients examined with PrLRs between January 1, 2008 and June 30, 2011. To compare the degree of pain provoked between standing extension lateral radiographs (StLRs) and PrLRs, numeric rating scale (NRS) scores were assessed and compared by a paired t-test. Vertebroplasty was done for 40 patients and kyphoplasty was done for 9 patients with routine manners. To assess the degree of postural reduction, vertebral wedge angles (VWA) and vertebral height ratios (VHR) were calculated by using preoperative StLRs, PrLRs, and postoperative lateral radiographs. Two variables derived from changes in VWA and VHR between preoperative and postoperative radiographs were compared by a paired t-test. The average NRS scores were 6.23 ± 1.67 in StLRs and 5.18 ± 1.47 in PrLRs. The degree of pain provocation was lower in using PrLRs than StLRs (p < 0.001). The average changes of VWA between preoperative and postoperative status were 5.24° ± 6.16° with PrLRs and 3.46° ± 3.47° with StLRs. The average changes of VHR were 0.248 ± 0.178 with PrLRs and 0.148 ± 0.161 with StLRs. The comparisons by two variables showed significant differences for both parameters (p = 0.021 and p < 0.001, respectively). The postoperative radiological status was reflected more precisely when using PrLRs than StLRs. In comparison with StLR, the PrLR was more accurate in predicting the degree of restoration of postoperative vertebral heights and wedge angles, and provoked less pain during examination. The PrLR could be a useful diagnostic tool to detect intravertebral cleft or intravertebral dynamic instability.

Osteogenesis imperfecta (OI) is an inherited heterogeneous bone fragility disorder, usually caused by collagen I mutations. It is well established that bisphosphonate treatment increases lumbar spine (LS) bone mineral density (BMD), as well as improves vertebral geometry in severe OI; however, fracture reduction has been difficult to prove, pharmacogenetic studies are scarce, and it is not known at which age, or severity of disease, treatment should be initiated. COL1A1 and COL1A2 were analyzed in 79 children with OI (type I n=33, type III n=25 and type IV n=21) treated with Pamidronate. Data on LS BMD, height, and radiologically confirmed non-vertebral and vertebral fractures were collected prior to, and at several time points during treatment. An increase in LS BMD Z-score was observed for all types of OI, and a negative correlation to Δ LS BMD was observed for both age and LS BMD Z-score at treatment initiation. Supine height Z-scores were not affected by Pamidronate treatment, The fracture rate was reduced for all OI types at all time points during treatment (overall p<0.0003, <0.0001 and 0.0003 for all OI types I, III and IV respectively). The reduced fracture rate was maintained for types I and IV, while an additional decrease was observed over time for type III. The fracture rate was reduced also in individuals with continued low BMD after >4yrs Pamidronate. Twice as many boys as girls with OI type I were treated with Pamidronate, and the fracture rate the year prior treatment was 2.2 times higher for boys (p=0.0236). Greater Δ LS BMD, but smaller Δ fracture numbers were observed on Pamidronate for helical glycine mutations in COL1A1 vs. COL1A2. Vertebral compression fractures did not progress in any individual during treatment; however, they did not improve in 9%, and these individuals were all >11years of age at treatment initiation (p<0.0001). Pamidronate treatment in children with all types of OI increased LS BMD, decreased fracture rate, and improved vertebral compression fractures. Fracture reduction was prompt and maintained during treatment, irrespective of age at treatment initiation and collagen I mutation type. Copyright © 2016 Elsevier Inc. All rights reserved.
Cervical spondylosis: a rare and curable cause of vertebrobasilar insufficiency.

Spondylotic vertebral artery (VA) compression is a rare cause of vertebrobasilar insufficiency and stroke. A 53-year-old man experienced multiple brief vertebrobasilar transient ischemic attacks (TIAs) and strokes, not apparently triggered by neck movements. Brain magnetic resonance imaging (MRI) documented consecutive infarcts, first in the left then right medial posterior inferior cerebellar artery (PICA) territories. Angiography showed two extracranial right vertebral artery (VA) stenoses, left VA hypoplasia, absence of left PICA and a dominant right PICA. Computed tomography angiography revealed right VA compression by osteophytes at C5-C6 and C6-C7 levels. No further vertebrobasilar insufficiency symptoms occurred in the 65 months following VA surgical decompression. Our literature review found 49 published surgical cases with vertebrobasilar symptoms caused by cervical spondylosis. Forty cases had one or more brief TIAs frequently triggered by neck movements. Three cases presented with stroke without prior TIA, with symptoms suggesting a top of the basilar artery embolic infarcts (one combined with a PICA infarct). Six cases had both TIAs and minor stroke. VA compression by uncovertebral osteophytes at the C5-C6 level was common. Dynamic angiography done in 38 cases systematically revealed worsening of VA stenosis or complete occlusion with either neck extension or rotation (ipsilateral when specified). Contralateral VA incompetence was found in 14 patients. Spondylotic VA stenosis can cause hemodynamic TIAs and watershed strokes, especially when contralateral VA insufficiency is combined to specific neck movements. Low-amplitude neck movement may suffice in severe cases. Embolic vertebrobasilar events are less frequent. VA decompression from spondylosis may prevent recurrent ischemic episodes.

Infantile hemangiomas (IH) are common vascular growths that occur in 5-10% of neonates and have the potential to cause disfiguring and even life-threatening complications. With no objective tool to monitor IH, a handheld wireless device (HWD) that uses diffuse optical spectroscopy has been developed for use in assessment of IH by measurements in absolute oxygenated and deoxygenated hemoglobin concentration as well as scattering in tissue. Reconstructions of these variables can be computed using a multispectral evolution algorithm. We validated the new system by experimental studies using phantom experiments and a clinical study is under way to assess the utility of DOI for IH.

A case of pericardial cavernous hemangioma is presented. A 62-year-old man had a chest pain and was referred to our hospital because of an abnormal shadow in the mediastinum. Chest computed tomography showed a hypervascular tumor of 2.0 cm in size at the left side of pulmonary artery. Magnetic resonance imaging findings suggested the mucinous part of the tumor, suggesting liposarcoma, thymoma, and neurinoma etc. At surgery, the tumor was found to be in the pericardial cavity. After pericardotomy, the tumor was resected. The diagnosis of the tumor was cavernous hemangioma. There was no evidence of recurrence 2 years after the operation.

Corneal vascular neoplasms (hemangioma and hemangiosarcoma) are rare in all species. Reported cases are single case reports in a single species. Archived cases of corneal hemangioma and hemangiosarcoma from dogs, cats, and horses were obtained from the Comparative Ocular Pathology Lab of Wisconsin (COPLOW, Madison, WI), tabulated, and examined. This retrospective study describes the breeds, ages, tumor types, and characteristics of vascular neoplasms that appeared to be primarily corneal in location, in feline, canine, and equine patients, with gross and histologic images. There is a discussion of predisposing factors and speculated association with chronic ocular surface disease. © 2018 American College of Veterinary Ophthalmologists.

PHACES syndrome associates a segmental facial hemangioma with cerebral malformations, aortic branches/cranial arteries anomalies, cardiac defects, eye anomalies or ventral wall defects. The aim of this study is to analyze our experience with this syndrome. Retrospective study of the cases seen at our unit in the last year. We treat 4 cases; 3 girls and 1 child. Besides the segmental hemangioma they presented: 3 vascular cerebral malformations; 2 structural cardiopathies; 2 cerebral malformations, 1 microftalmia. We did not find ventral wall defects. A case received treatment with two cycles of metilprednisolone i.v. and oral prednisone, with favourable course; two cases received initial treatment with oral prednisone continued of oral propanolol in rising pattern up to 2 mg/kg/day, Obtaining both the detention of the tumour growth and regression of the lesion, with very good tolerance. A 7-year-old patient has been treated with colouring pulse laser for her residual lesions. When we see a segmental facial hemangioma we must perform a wide diagnostic study in order to discard a PHACES syndrome. Multidisciplinar approach to the patient by a wide expert's group gets an earlier diagnose and improves the outcome. Propranolol is a promising therapeutic alternative.

Tuberous sclerosis (TSC) is a autosomal dominant genetic disorder caused by mutations in either TSC1 or TSC2, and characterized by benign hamartoma growth. We developed a murine model of Tsc1 disease by gene targeting. Tsc1 null embryos die at mid-gestation from a failure of liver development. Tsc1 heterozygotes develop kidney cystadenomas and liver hemangiomas at high frequency, but the incidence of kidney tumors is somewhat lower than in Tsc2 heterozygote mice. Liver hemangiomas were more common, more severe and caused higher mortality in female than in male Tsc1 heterozygotes. Tsc1 null embryo fibroblast lines have persistent phosphorylation of the p70S6K (S6K) and its substrate S6, that is sensitive to treatment with rapamycin, indicating constitutive activation of the mTOR-S6K pathway due to loss of the Tsc1 protein, hamartin. Hyperphosphorylation of S6 is also seen in kidney tumors in the heterozygote mice, suggesting that inhibition of this pathway may have benefit in control of TSC hamartomas.

Vascular anomalies comprise malformations, hemangiomas, and rare tumors. The commonality among these lesions is their origin in vascular endothelia. Most occur sporadically, but occasional inheritance is observed and thus allows genetic research and insight into etiology. This review highlights those vascular anomalies in which genetic inheritance has been demonstrated. A comprehensive literature search was performed on PubMed. Fifty-five full-length articles were reviewed. Five categories of vascular anomalies with patterned inheritance were identified: arteriovenous malformation (AVM), capillary malformation (CM), lymphatic malformation (LM), venous malformation (VM), and infantile hemangioma (IH). Capillary and arteriovenous malformation subtypes are associated with a RASA-1 gene mutation and show autosomal dominant inheritance. VEGFR3 mutations have been associated with generalized forms of LM and lymphedema. Mutations in TIE2/TEK genes cause inherited forms of venous malformations also with autosomal dominant inheritance. Familial clustering and atopic disease are associated with infantile hemangioma, and gene expression varies with the developmental stage of these lesions. Most vascular anomalies occur sporadically, but several genes and genetic disorders have been associated with them. Specific forms of capillary malformation appear to be most convincingly associated with genomic errors. Further research promises new insights into the development of this diverse group of disorders.

Spondyloptosis refers to complete dislocation of a vertebral body onto another. The L5-S1 level is frequently affected. As this condition is rare, few published reports describing its clinical features and surgical outcomes exist, especially in the pediatric patient population. The authors report the presentation, pathological findings, and radiographic studies of a 2-year-old girl who presented to Texas Children's Hospital with a history since birth of progressive spastic paraparesis. Preoperative CT and MRI showed severe spinal cord compression associated with T11-12 spondyloptosis. The patient underwent a single-stage posterior approach for complete resection of the dysplastic vertebral bodies at the apex of the spinal deformity with reconstruction and stabilization of the vertebral column using a titanium expandable cage and pedicle screws. At the 12-month follow-up, the patient remained neurologically stable without any radiographic evidence of instrumentation failure or loss of alignment. To the best of the authors' knowledge, there have been only 2 other children with congenital thoracolumbar spondyloptosis treated with the above-described strategy. The authors describe their case and review the literature to discuss the aggregate clinical features, surgical strategies, and operative outcomes for congenital thoracolumbar spondyloptosis.

Vertebral compression fractures are the most common osteoporotic fractures. Since the introduction of vertebroplasty and screw augmentation, the management of osteoporotic fractures has changed significantly. The biomechanical characteristics of the risk of adjacent fractures and novel treatment modalities for osteoporotic vertebral fractures, including pure cement augmentation by vertebroplasty, and cement augmentation of screws for posterior instrumentation, are explored. Eighteen human osteoporotic lumbar spines (L1-5) adjacent to vertebral bodies after vertebroplasty were tested in a servo-hydraulic machine. As augmentation compounds we used standard cement and a modified low-strength cement. Different anchoring pedicle screws were tested with and without cement augmentation in another cohort of human specimens with a simple pull-out test and a fatigue test that better reflects physiological conditions. Cement augmentation in the osteoporotic spine leads to greater biomechanical stability. However, change in vertebral stiffness resulted in alterations with the risk of adjacent fractures. By using a less firm cement compound, the risk of adjacent fractures is significantly reduced. Both screw augmentation techniques resulted in a significant increase in the withdrawal force compared with the group without cement. Augmentation using perforated screws showed the highest stability in the fatigue test. The augmentation of cement leads to a significant change in the biomechanical properties. Differences in the stability of adjacent vertebral bodies increase the risk of adjacent fractures, which could be mitigated by a modified cement compound with reduced strength. Screws that were specifically designed for cement application displayed greatest stability in the fatigue test.

A 2-year-old, spayed female, German short-haired pointer was presented with a 1-day history of non-ambulatory paraplegia with absent deep pain perception. A computed tomography scan revealed an irregular eighth thoracic vertebral body and an extradural compressive lesion. Decompression was performed and abnormal tissues were submitted for analysis. Findings were consistent with a Cryptococcus gattii infection. PMID:24155428

The purpose of this prospective multicentric observational study was to confirm the safety and clinical performance of a craniocaudal expandable implant used in combination with high viscosity PMMA bone cement for the treatment of vertebral compression fractures. Thirty-nine VCFs in 32 patients were treated using the SpineJack minimally invasive surgery protocol. Outcome was determined by using the Visual Analogue Scale for measuring pain, the Oswestry Disability Index for scoring functional capacity, and the self-reporting European Quality of Life scores for the quality of life. Safety was evaluated by reporting all adverse events. The occurrence of cement leakages was assessed by either radiographs or CT scan or both. Statistically significant improvements were found regarding pain, function, and quality of life. The global pain score reduction at 1 year was 80.9% compared to the preoperative situation and the result of the Oswestry Disability Index showed a decrease from 65.0% at baseline to 10.5% at 12 months postoperatively. The cement leakage rate was 30.8%. No device- or surgery-related complications were found. This observational study demonstrates promising and persistent results consisting of immediate and sustained pain relief and durable clinical improvement after the procedure and throughout the 1-year follow-up period.

Cervical radiculopathy secondary to compression from vertebral artery (VA) tortuosity is a rare entity. We describe successful transposition through an anterolateral approach of tortuous VA loops causing cervical radiculopathy. Two patients with cervical radiculopathy (first case at C5-6 and second case at C3-4) secondary to anomalous VA loop compression underwent anterolateral approaches to the cervical spine for decompression and VA transposition. The anterior transverse foramina were drilled to unroof the VA loop, which was dissected free from the exiting nerve root. In both cases, the affected cervical nerve root was successfully decompressed with both radiographic and clinical improvements in radiculopathy symptoms. We found 8 other cases of VA transposition via either an anterolateral approach or a posterolateral approach described in the literature. Our second case of anterolateral VA transposition at the C3-4 level is the first case at this level and the highest level reported in the literature. Decompression using an anterolateral approach with direct microvascular transposition of the VA is a safe and effective treatment of this pathology and addresses the cause of radiculopathy more directly than the posterolateral approach.

PurposeThis study was designed to assess the clinical outcomes of patients treated by vertebral augmentation with nitinol endoprosthesis (VNE) to treat painful vertebral compression fractures.MethodsForty patients with one or more painful osteoporotic VCF, confirmed by MRI and accompanied by back-pain unresponsive to a minimum 2 months of conservative medical treatment, underwent VNE at 42 levels. Preoperative and postoperative pain measured with Visual Analog Scale (VAS), disability measured by Oswestry Disability Index (ODI), and vertebral height restoration (measured with 2-dimensional reconstruction CT) were compared at last follow-up (average follow-up 15 months). Cement extravasation, subsequent fractures, and implant migration were recorded.ResultsLong-term follow-up was obtainedmore » in 38 of 40 patients. Both VAS and ODI significantly improved from a median of 8.0 (range 5–10) and 66 % (range 44–88 %) to 0.5 (range 0–8) and 6 % (range 6–66 %), respectively, at 1 year (p < 0.0001). Vertebral height measurements comparing time points increased in a statistically significant manner (ANOVA, p < 0.001). Overall cement extravasation rate was 9.5 %. Discal and venous leakage rates were 7.1 and 0 % respectively. No symptomatic extravasations occurred. Five of 38 (13.1 %) patients experienced new spontaneous, osteoporotic fractures. No device change or migration was observed.ConclusionsVNE is a safe and effective procedure that is able to provide long-lasting pain relief and durable vertebral height gain with a low rate of new fractures and cement leakages.« less

Purpose: To determine our institutional vertebral compression fracture (VCF) rate after spine stereotactic radiosurgery (SRS) and determine contributory factors. Methods and Materials: Retrospective analysis from 2001 to 2013 at a single institution was performed. With institutional review board approval, electronic medical records of 1905 vertebral bodies from 791 patients who were treated with SRS for the management of primary or metastatic spinal lesions were reviewed. A total of 448 patients (1070 vertebral bodies) with adequate follow-up imaging studies available were analyzed. Doses ranging from 10 Gy in 1 fraction to 60 Gy in 5 fractions were delivered. Computed tomography and magnetic resonancemore » imaging were used to evaluate the primary endpoints of this study: development of a new VCF, progression of an existing VCF, and requirement of stabilization surgery after SRS. Results: A total of 127 VCFs (11.9%; 95% confidence interval [CI] 9.5%-14.2%) in 97 patients were potentially SRS induced: 46 (36%) were de novo, 44 (35%) VCFs progressed, and 37 (29%) required stabilization surgery after SRS. Our rate for radiologic VCF development/progression (excluding patients who underwent surgery) was 8.4%. Upon further exclusion of patients with hematologic malignancies the VCF rate was 7.6%. In the univariate analyses, females (hazard ratio [HR] 1.54, 95% CI 1.01-2.33, P=.04), prior VCF (HR 1.99, 95% CI 1.30-3.06, P=.001), primary hematologic malignancies (HR 2.68, 95% CI 1.68-4.28, P<.001), thoracic spine lesions (HR 1.46, 95% CI 1.02-2.10, P=.02), and lytic lesions had a significantly increased risk for VCF after SRS. On multivariate analyses, prior VCF and lesion type remained contributory. Conclusions: Single-fraction SRS doses of 16 to 18 Gy to the spine seem to be associated with a low rate of VCFs. To the best of our knowledge, this is the largest reported experience analyzing SRS-induced VCFs, with one of the lowest event rates reported.« less

The KAST (Kiva Safety and Effectiveness Trial) study was a pivotal, multicenter, randomized control trial for evaluation of safety and effectiveness in the treatment of patients with painful, osteoporotic vertebral compression fractures (VCFs). The objective was to demonstrate noninferiority of the Kiva system to balloon kyphoplasty (BK) with respect to the composite primary endpoint. Annual incidence of osteoporotic VCFs is prevalent. Optimal treatment of VCFs should address pain, function, and deformity. Kiva is a novel implant for vertebral augmentation in the treatment of VCFs. A total of 300 subjects with 1 or 2 painful osteoporotic VCFs were randomized to blindly receive Kiva (n = 153) or BK (n = 147). Subjects were followed through 12 months. The primary endpoint was a composite at 12 months defined as a reduction in fracture pain by at least 15 mm on the visual analogue scale, maintenance or improvement in function on the Oswestry Disability Index, and absence of device-related serious adverse events. Secondary endpoints included cement usage, extravasation, and adjacent level fracture. A mean improvement of 70.8 and 71.8 points in the visual analogue scale score and 38.1 and 42.2 points in the Oswestry Disability Index was noted in Kiva and BK, respectively. No device-related serious adverse events occurred. Despite significant differences in risk factors favoring the control group at baseline, the primary endpoint demonstrated noninferiority of Kiva to BK. Analysis of secondary endpoints revealed superiority with respect to cement use and site-reported extravasation and a positive trend in adjacent level fracture warranting further study. The KAST study successfully established that the Kiva system is noninferior to BK based on a composite primary endpoint assessment incorporating pain-, function-, and device-related serious adverse events for the treatment of VCFs due to osteoporosis. Kiva was shown to be noninferior to BK and revealed a positive trend in several secondary endpoints. 1.

ABSTRACT Serum ferritin concentration increases in dogs in association with various diseases. In this study, we measured serum ferritin levels in dogs with splenic masses, using a sandwich ELISA assay. Eleven dogs with hemangiosarcoma (HSA), six with hematoma, 1 with hemangioma and 3 with lymphoma were enrolled. All dogs with HSA had serum ferritin concentrations above the normal limit (1,357 ng/ml, mean + 2× standard deviation of normal). Increased serum ferritin concentrations have also been observed in few cases of hematoma, hemangioma and lymphoma. Therefore, hyperferritinemia is not specific for splenic HSA, but may have clinical usefulness as a sensitive test for the disease. Further evaluation of serum ferritin concentrations in dogs with splenic HSA is needed. PMID:23803459

Pulmonary sclerosing hemangioma (PSH) is a rare tumor accounting for 0.2-1% of all primary lung tumors. Simultaneous occurrence of PSH with breast cancer has very rarely been reported in the literature. We describe here a case of simultaneous occurrence of PSH with breast cancer. A pathological diagnosis of PSH was confirmed by computed tomography (CT)-guided biopsy. Due to the patient's poor performance status and the benign nature of PSH, surgical excision was not considered and the patient was managed conservatively with regular follow-up. Although surgical excision is the preferred treatment for PSH, conservative management may be a reasonable option in carefully selected patients.
Diagnosis and management of hemangiomas and vascular malformations of the head and neck.

Vascular anomalies are congenital errors in vascular development. They frequently involve the head, neck, and oral cavity. Subdivided into vascular tumors (hemangiomas) and vascular malformations, vascular anomalies remain poorly understood. However, growing interest and recent advances in the diagnosis, management, and molecular characterization of these lesions are improving treatment strategies. The role of the multidisciplinary team cannot be overstated. This review provides both basic and up-to-date knowledge on the most common vascular anomalies encountered by physicians and practitioners. Because treatment options for vascular anomalies are widely variable and often debated, this report aims to provide a comprehensive approach to these lesions based upon current concepts and practical clinical experience.
Prevalence of Poor Bone Quality in Women Undergoing Spinal Fusion Using Biomechanical-CT Analysis.

2016-02-01
Retrospective, cross-sectional analysis of vertebral bone quality in spine-fusion patients at a single medical center. To characterize the prevalence of osteoporosis and fragile bone strength in a spine-fusion population of women with an age range of 50 years to 70 years. Fragile bone strength is defined as the level of vertebral strength below which a patient is at as high a risk of future vertebral fracture as a patient having bone density-defined osteoporosis. Poor bone quality--defined here as the presence of either osteoporosis or fragile bone strength--is a risk factor for spine-fusion patients that often goes undetected but can now be assessed preoperatively by additional postprocessing of computed tomography (CT) scans originally ordered for perioperative clinical assessment. Utilizing such perioperative CT scans for a cohort of 98 women (age range: 51-70 yr) about to undergo spine fusion, we retrospectively used a phantomless calibration technique and biomechanical-CT postprocessing analysis to measure vertebral trabecular bone mineral density (BMD) (in mg/cm³) and by nonlinear finite element analysis, vertebral compressive strength (in Newtons, N) in the L1 or L2 vertebra. Preestablished validated threshold values were used to define the presence of osteoporosis (trabecular BMD of 80 mg/cm³ or lower) and fragile bone strength (vertebral strength of 4500 N or lower). Fourteen percent of the women tested positive for osteoporosis, 27% tested positive for fragile bone strength, and 29% were classified as having poor bone quality (either osteoporosis or fragile bone strength). Over this narrow age range, neither BMD nor vertebral strength were significantly correlated with age, weight, height, or body mass index (P values 0.14-0.97 for BMD; 0.13-0.51 for strength). Poor bone quality appears to be common in women between ages 50 years and 70 years undergoing spinal fusion surgery. 3.

Purpose We aimed to evaluate the histologic and radiologic findings of vascular lesions after stereotactic radiosurgery (SRS) categorized as radiation-induced cavernous hemangioma (RICH). Materials and Methods Among 89 patients who underwent neurosurgery for cavernous hemangioma, eight RICHs from 7 patients and 10 de novo CHs from 10 patients were selected for histopathological and radiological comparison. Results Histologically, RICHs showed hematoma-like gross appearance. Microscopically, RICH exhibited a hematoma-like area accompanied by proliferation of thin-walled vasculature with fibrin deposits and infiltrating foamy macrophages. In contrast, CHs demonstrated localized malformed vasculature containing fresh and old clotted blood on gross examination. Typically, CHs consisted of thick, ectatic hyalinized vessels lined by endothelium under a light microscope. Magnetic resonance imaging of RICHs revealed some overlapping but distinct features with CHs, including enhancing cystic and solid components with absence or incomplete popcorn-like appearance and partial hemosiderin rims. Conclusion Together with histologic and radiologic findings, RICH may result from blood-filled space after tissue destruction by SRS, accompanied with radiation-induced reactive changes rather than vascular malformation. Thus, the term "RICH" would be inappropriate, because it is more likely to be an inactive organizing hematoma rather than proliferation of malformed vasculature. PMID:26446658

Extremely few in-vitro biomechanical studies have incorporated shear loads leaving a gap for investigation, especially when applied in combination with compression and bending under dynamic conditions. The objective of this study was to biomechanically compare sagittal plane application of two standard protocols, pure moment (PM) and follower load (FL), with a novel trunk weight (TW) loading protocol designed to induce shear in combination with compression and dynamic bending in a neutrally potted human cadaveric L4-L5 motion segment unit (MSU) model. A secondary objective and novelty of the current study was the application of all three protocols within the same testing system serving to reduce artifacts due to testing system variability. Six L4-L5 segments were tested in a Cartesian load controlled system in flexion-extension to 8Nm under PM, simulated ideal 400N FL, and vertically oriented 400N TW loading protocols. Comparison metrics used were rotational range of motion (RROM), flexibility, neutral zone (NZ) range of motion, and L4 vertebral body displacements. Significant differences in vertebral body translations were observed with different initial force applications but not with subsequent bending moment application. Significant reductions were observed in combined flexion-extension RROM, in flexibility during extension, and in NZ region flexibility with the TW loading protocol as compared to PM loading. Neutral zone ranges of motion were not different between all protocols. The combined compression and shear forces applied across the spinal joint in the trunk weight protocol may have a small but significantly increased stabilizing effect on segment flexibility and kinematics during sagittal plane flexion and extension.

Purpose The aim of the International Myeloma Working Group was to develop practice recommendations for the management of multiple myeloma (MM) –related bone disease. Methodology An interdisciplinary panel of clinical experts on MM and myeloma bone disease developed recommendations based on published data through August 2012. Expert consensus was used to propose additional recommendations in situations where there were insufficient published data. Levels of evidence and grades of recommendations were assigned and approved by panel members. Recommendations Bisphosphonates (BPs) should be considered in all patients with MM receiving first-line antimyeloma therapy, regardless of presence of osteolytic bone lesions on conventional radiography. However, it is unknown if BPs offer any advantage in patients with no bone disease assessed by magnetic resonance imaging or positron emission tomography/computed tomography. Intravenous (IV) zoledronic acid (ZOL) or pamidronate (PAM) is recommended for preventing skeletal-related events in patients with MM. ZOL is preferred over oral clodronate in newly diagnosed patients with MM because of its potential antimyeloma effects and survival benefits. BPs should be administered every 3 to 4 weeks IV during initial therapy. ZOL or PAM should be continued in patients with active disease and should be resumed after disease relapse, if discontinued in patients achieving complete or very good partial response. BPs are well tolerated, but preventive strategies must be instituted to avoid renal toxicity or osteonecrosis of the jaw. Kyphoplasty should be considered for symptomatic vertebral compression fractures. Low-dose radiation therapy can be used for palliation of uncontrolled pain, impending pathologic fracture, or spinal cord compression.

Neurons selective to the number of visual items in the corvid songbird endbrain
Ditz, Helen M.; Nieder, Andreas
2015-01-01
It is unknown whether anatomical specializations in the endbrains of different vertebrates determine the neuronal code to represent numerical quantity. Therefore, we recorded single-neuron activity from the endbrain of crows trained to judge the number of items in displays. Many neurons were tuned for numerosities irrespective of the physical appearance of the items, and their activity correlated with performance outcome. Comparison of both behavioral and neuronal representations of numerosity revealed that the data are best described by a logarithmically compressed scaling of numerical information, as postulated by the Weber–Fechner law. The behavioral and neuronal numerosity representations in the crow reflect surprisingly well those found in the primate association cortex. This finding suggests that distantly related vertebrates with independently developed endbrains adopted similar neuronal solutions to process quantity. PMID:26056278

There is a wide clinicopathologic spectrum of vascular proliferations characterized by the presence of epithelioid endothelial cells, comprising epithelioid hemangioma (EH)-pseudomyogenic (epithelioid sarcoma-like) hemangioendothelioma (PM-HAE), epithelioid hemangioendothelioma, and epithelioid angiosarcoma. Immunohistochemical FOS-B expression as well as FOS-B rearrangement (fluorescent in situ hybridization [FISH]) have recently been described as diagnostically relevant underpinnings of EH (restricted to osseous lesions) and PM-HAE. The aim of this study was to clinicopathologically characterize and to elucidate FOS-B expression in patients with eruptive lesions of the cellular variant of cutaneous EH. All cases of cutaneous cellular EH (n=16) showed strong diffuse immunohistochemical expression of FOS-B, in conjunction with positivity for ERG and nestin. Expression of MYC, CAMTA-1, AE1/3, and MNF116 was negative in all cases. FISH investigations did not show any sign of rearrangements for CAMTA-1 or MYC amplification. Negative-control cases included 15 lobular hemangiomas, 5 epithelioid angiosarcomas, and 5 nodular Kaposi sarcomas, all of which were negative for FOS-B. Positive-control cases included 15 angiolymphoid hyperplasia with eosinophilia cases, all of them being positive. In contrast with what has been published so far, cutaneous variants of cellular EH exhibit positive immunostaining for FOS-B. Remarkably, FOS-B expression is not restricted to the intraosseous subset of EH. For differential diagnosis of epithelioid vascular tumors, we therefore suggest a helpful panel of antibodies including CAMTA-1, TFE-3, FOS-B, and AE1/AE3. We point out the telltale immunophenotypes: angiolymphoid hyperplasia with eosinophilia and EH (FOS-B/others negative), PM-HAE (FOS-B/AE1/AE3/others negative), epithelioid hemangioendothelioma (CAMTA-1 or TFE-3/others negative). Remarkably, MYC is not expressed in these tumors, neither is there an MYC amplification by FISH. We suggest the term multiple eruptive EHs for this subset of cutaneous vascular tumors.

Laparoscopic major hepatectomy remains a challenging procedure [1, 2]. In the case of giant tumors in the right liver, conventional approach (complete mobilization of the right liver before parenchymal transection) could be dangerous during mobilization because of large volume and weight [3, 4]. We present the case of a pure laparoscopic right hepatectomy for a giant hemangioma using an anterior approach. We achieved the informed consent with this patient and approved by the Ethics Committee of the Asan Medical Center. Giant hemangioma (13 × 11 × 14 cm) was located in right liver. After glissonean approach [5], Pringle maneuver was performed during the hepatic parenchymal transection. For the transection, the Cavitron Ultrasonic Surgical Aspirator was used. Small hepatic vein branches along the middle hepatic vein and small glissonean pedicles were sealed and divided with a THUNDERBEATTM (Olympus), which is the device with integration of both bipolar and ultrasonic energies delivered simultaneously. iDriveTM Ultra Powered Stapling device (Medtronic) was used for division of right glissonean pedicle and large hepatic veins. Hemangioma was removed through the lower abdominal transverse incision using the endo-bag. This technique has the advantage of avoiding excessive bleeding caused by avulsion of the hepatic vein and caval branches, iatrogenic tumor rupture [3]. By means of the anterior approach, pure laparoscopic right hepatectomy was performed successfully without intraoperative complications and transfusions. The operation time was 202 min, and the estimated blood loss was less than 150 ml. On postoperative day 3, computed tomographic scan showed no pathological findings. The patient was discharged on postoperative day 5 without complications. Laparoscopic approach has good results because of the view with magnification enabling meticulous hemostasis and the small wounds that give patients less pain [6, 7]. The authors recommend that the laparoscopic anterior approach is safe and feasible for right hepatectomy, even for giant tumors.

This study aims to investigate the curative effects and mechanism of radiofrequency ablation nucleoplasty in the treatment of cervical vertigo. A total of 27 patients diagnosed with cervical vertigo from January 2012 to October 2014 received treatment of radiofrequency ablation nucleoplasty. The narrow-side vertebral artery diameters were examined by using Philips 1.5-T body dual-gradient MRI system. The haemodynamic parameters were detected by using transcranial Doppler sonography. Both of the vertebral artery diameters and haemodynamic parameters were recorded and compared before and after treatment. The curative effects in early post-operative application were evaluated according to the Nagashima standards. Radiofrequency ablation nucleoplasty was performed in a total of 59 cervical discs in 27 patients. The average operation time was 42.7 min, and the symptoms of 92.6% patients were alleviated after radiofrequency ablation nucleoplasty post-operation application. There was no significant difference in the narrow-side vertebral artery diameters before and after treatment in both Group A (p = 0.12) and Group B (p = 0.48); however, the blood flow velocity was significantly higher than that before treatment in both Group A (p = 0.01) and Group B (p = 0.03), respectively. Radiofrequency ablation nucleoplasty improves the blood flow in the narrow-side vertebral artery and illustrates the therapeutic effect on cervical vertigo in patients who have no direct compression of the vertebral artery. Advances in knowledge: Radiofrequency intradiscal nucleoplasty can be used as a minimally invasive procedure for treating cervical vertigo.

In pre-pubertal girls, nutrient intakes and non-aquatic organized activity were evaluated as factors in vertebral body bone mass, structure, and strength. Activity, vitamin B 12 , and dietary fiber predicted bone outcomes most consistently. Exercise and vitamin B 12 appear beneficial, whereas high fiber intake appears to be adverse for vertebral body development. Childhood development sets the baseline for adult fracture risk. Most studies evaluate development using postero-anterior (PA) dual-energy X-ray absorptiometry (DXA) areal bone mineral density, bone mineral content, and bone mineral apparent density. In a prior analysis, we demonstrated that PA DXA reflects posterior element properties, rather than vertebral body fracture sites, such that loading is associated with subtle differences in vertebral body geometry, not 3D density. The current analysis is restricted to pre-pubertal girls, for a focused exploration of key nutrient intakes and physical activity as factors in dual plane indices of vertebral body geometry, density, and strength. This cross-sectional analysis used paired PA and supine lateral (LAT) lumbar spine DXA scans to assess "3D" vertebral body bone mineral apparent density (PALATBMAD), "3D" index of structural strength in axial compression (PALATIBS), and fracture risk index (PALATFRI). Diet data were collected using the Youth/Adolescent Questionnaire (YAQ, 1995); organized physical activity was recorded via calendar-based form. Pearson correlations and backward stepwise multiple linear regression analyzed associations among key nutrients, physical activity, and bone outcomes. After accounting for activity and key covariates, fiber, unsupplemented vitamin B 12 , zinc, carbohydrate, vitamin C, unsupplemented magnesium, and unsupplemented calcium intake explained significant variance for one or more bone outcomes (p < 0.05). After adjustment for influential key nutrients and covariates, activity exposure was associated with postero-anterior (PA) areal bone mineral density, PA bone mineral content, PA width, lateral (LAT) BMC, "3D" bone cross-sectional area (coronal plane), "3D" PALATIBS, and PALATFRI benefits (p < 0.05). Physical activity, fiber intake, and unsupplemented B 12 intake appear to influence vertebral body bone mass, density, geometry, and strength in well-nourished pre-pubertal girls; high fiber intakes may adversely affect childhood vertebral body growth.

The increasing incidence of spinal metastasis, a result of improved systemic therapies for cancer, has spurred a search for an alternative method for the surgical treatment of lumbar metastases. The authors report a single-stage posterior-only approach for resecting any pathological lumbar vertebral segment and reconstructing with a medium to large expandable cage while preserving all neurological structures. The authors conducted a retrospective consecutive case review of 11 patients (5 women, 6 men) with spinal metastases treated at 1 institution with single-stage posterior-only vertebral column resection and reconstruction with an expandable cage and pedicle screw fixation. For all patients, the indications for operative intervention were spinal cord compression, cauda equina compression, and/or spinal instability. Neurological status was classified according to the American Spinal Injury Association impairment scale, and functional outcomes were analyzed by using a visual analog scale for pain. For all patients, a circumferential vertebral column resection was achieved, and full decompression was performed with a posterior-only approach. Each cage was augmented by posterior pedicle screw fixation extending 2 levels above and below the resected level. No patient required a separate anterior procedure. Average estimated blood loss and duration of each surgery were 1618 ml (range 900-4000 ml) and 6.6 hours (range 4.5-9 hours), respectively. The mean follow-up time was 14 months (range 10-24 months). The median survival time after surgery was 17.7 months. Delayed hardware failure occurred for 1 patient. Preoperatively, 2 patients had intractable pain with intact lower-extremity strength and 8 patients had severe intractable pain, lower-extremity paresis, and were unable to walk; 4 of whom regained the ability to walk after surgery. Two patients who were paraplegic before decompression recovered substantial function but remained wheelchair bound, and 2 patients remained paraparetic after the surgery. No patients had lasting intraoperative neuromonitoring changes, and none died. Complications included 2 reoperations, 1 delayed hardware failure (cage subsidence that did not require revision), and 3 incidental durotomies (none of which required reoperation). No postoperative pneumonia, ileus, or deep venous thrombosis developed in any patient. A posterior-only approach for vertebral segment resection with preservation of spinal nerve roots is a viable technique that can be used throughout the entire lumbar spine. Extensive mobilization of the nerve roots is of utmost importance and allows for insertion and expansion of medium-sized, in situ expandable cages in the midline. This approach, although technically challenging, might reduce the morbidity associated with an anterior approach.
Facial nerve hemangioma: a rare case involving the vertical segment.

This case report and literature review reports on a rare case of facial nerve hemangioma (FNH) involving the vertical facial nerve (FN) segment, and discusses the clinical presentation, imaging, pathogenesis, and management of these rare lesions. A 53-year-old male presented with a 10-year history of right hemifacial twitching and progressive facial paresis (House-Brackmann grading score V/VI). The computed tomography and magnetic resonance imaging studies confirmed an expansile lesion along the vertical FN segment. Excision and histopathologic examination demonstrated FNH. FNHs involving the vertical FN segment are extremely rare. Despite being rare lesions, we believe that familiarity with the presentation and management of FNHs are imperative. Laryngoscope, 2012.

Analysis of the incidence of Venous Compression Syndrome (VCS) with full block of the flow of the internal jugular veins (IJVs) in patients with Multiple Sclerosis and Chronic cerebro-spinal venous insufficiency. We included 769 patients with MS and CCSVI (299 males, 470 females) and 210 controls without ms and ccsvi (92 males, 118 females). each subject was investigated by echo-color-doppler (ecd). morphological and hemodynamic ecd data were recorded by a computerized mem-net maps of epidemiological national observatory on ccsvi and they were analyzed by mem-net clinical analysis programs. VCS of IJVs occurs in 240 subjects affected by CCSVI and MS (31% of total) and in 12 controls (6% of total). The differences between the two groups are statistical significant (X² = 36.64, p<0.0001). Up to day there are no longitudinal studies that allow us to identify the WC of jugular and/or vertebral veins as etiology of a chronic neurodegenerative disease, but we note that Venous Compression Syndrome of IJVs is strongly associated with MS and CCSVI.

A 61-yr-old woman presented with complaints of weakness and pain in her legs. A magnetic resonance imaging showed a 3 x 5.6 x 7.8 cm mass lesion destructing the T1 and T2 vertebral bodies and compressing the spinal cord. The mass was excised surgically. It was follicular carcinoma metastasis of the cervicodorsal region. Then, she underwent a total thyroidectomy. Pathological examination showed two different types of carcinomas in two different focuses; follicular carcinoma in the left lobe and follicular variant papillary carcinoma in the isthmic lobe. After the operation she was given 100 mCi 131I. This is the first report of a patient who had both metastatic follicular carcinoma and follicular variant papillary carcinoma together.

The results of the present study confirm the efficacy of combined differential treatment of pain sensation in the lower back with the use of the up-to-date physiotherapeutic methods. The choice of a concrete method depended on the mechanism of development of the vertebral syndrome (compression, disfixation, disgenia or aseptic inflammation). The treatment resulted in the improvement of major integral characteristics of the pathological process, marked reduction in the duration of therapy, and significant prolongation of the remission period.

Valveless pumping phenomena (peristalsis, Liebau-effect) can generate unidirectional fluid flow in periodically compressed tubular conduits. Early embryonic hearts are tubular conduits acting as valveless pumps. It is unclear whether such hearts work as peristaltic or Liebau-effect pumps. During the initial phase of its pumping activity, the originally straight embryonic heart is subjected to deforming forces that produce bending, twisting, kinking, and coiling. This deformation process is called cardiac looping. Its function is traditionally seen as generating a configuration needed for establishment of correct alignments of pulmonary and systemic flow pathways in the mature heart of lung-breathing vertebrates. This idea conflicts with the fact that cardiac looping occurs in all vertebrates, including gill-breathing fishes. We speculate that looping morphogenesis may improve the efficiency of valveless pumping. To test the physical plausibility of this hypothesis, we analyzed the pumping performance of a Liebau-effect pump in straight and looped (kinked) configurations. Compared to the straight configuration, the looped configuration significantly improved the pumping performance of our pump. This shows that looping can improve the efficiency of valveless pumping driven by the Liebau-effect. Further studies are needed to clarify whether this finding may have implications for understanding of the form-function relationship of embryonic hearts.

Kummell's disease, caused by osteonecrosis of the vertebral body, is a cause of vertebral collapse. In Kummell's disease, intravertebral instability from nonunion between the cement and bone after percutaneous vertebroplasty (PVP) can cause persistent severe pain and dysfunction. A 75-year-old woman presented with severe pain in the lower back, both buttocks, groin, and both posterior thighs for a period of 30 days. Lumbar radiographs and magnetic resonance images showed an acute compression fracture of the first lumbar vertebra with an intravertebral cleft filled with fluid. The patient underwent PVP for the L1 compression fracture; however, this failed to provide sufficient pain relief. The patient was re-evaluated with dynamic radiography, and intravertebral instability and bone cement displacement of the L1 vertebra were detected. Repeat PVP was performed. After the procedure, intravertebral instability was restored and her pain completely subsided. PVP is a good treatment choice for symptomatic Kummell's disease. However, there is no consensus on the best technique of injecting bone cement to achieve optimal results. It is important to inject more bone cement than the volume of the intravertebral cleft to prevent instability caused by nonunion in PVP for Kummell's disease. We report a case of failed PVP because of insufficient correction of intravertebral instability in Kummell's, along with a review of the literature. © 2017 World Institute of Pain.

To compare the clinical outcome and complications of high viscosity and low viscosity poly-methyl methacrylate bone cement PVP for severe OVCFs. From December 2010 to December 2012, 32 patients with severe OVCFs were randomly assigned to either group H using high viscosity cement (n=14) or group L using low viscosity cement (n=18). The clinical outcomes were assessed by the Visual Analog Scale (VAS), Oswestry Disability Index (ODI), Short Form-36 General Health Survey (SF-36), kyphosis Cobb's angle, vertebral height, and complications. Significant improvement in the VAS, ODI, SF-36 scores, kyphosis Cobb's angle, and vertebral height were noted in both the groups, and there were no significant differences between the two groups. Cement leakage was seen less in group H. Postoperative assessment using computed tomography identified cement leakage in 5 of 17 (29.4%) vertebrae in group H and in 15 of 22 (68.2%) vertebrae in group L (P=0.025). The PVP using high viscosity bone cement can provide the same clinical outcome and fewer complications compared with PVP using low viscosity bone cement. Copyright © 2014. Published by Elsevier B.V.

Estrogen withdrawal in postmenopausal women increases bone loss and bone fragility in the vertebra. Bone loss with osteoporosis not only reduces bone mineral density (BMD), but actually alters bone quality, which can be comprehensively represented by bone post-yield behaviors. This study aimed to provide some information as to how osteoporosis induced by estrogen depletion could influence the evolution of post-yield microdamage accumulation and plastic deformation in vertebral bodies. This study also tried to reveal the part of the mechanisms of how estrogen deficiency-induced osteoporosis would increase the bone fracture risk. A rat bilateral ovariectomy (OVX) model was used to induce osteoporosis. Progressive cyclic compression loading was developed for vertebra testing to elucidate the post-yield behaviors. BMD, bone volume fraction, stiffness degradation, and plastic deformation evolution were compared among rats raised for 5 weeks (ovx5w and sham5w groups) and 35 weeks (ovx35w and sham35w groups) after sham surgery and OVX. The results showed that a higher bone loss in vertebral bodies corresponded to lower stiffness and higher plastic deformation. Thus, osteoporosis could increase the vertebral fracture risk probably through microdamage accumulation and plastic deforming degradation.

Diagnosis of lumbar foraminal stenosis remains difficult. Here, we report on a case in which bilateral lumbar foraminal stenosis was difficult to diagnose, and in which diffusion tensor imaging (DTI) was useful. The patient was a 52-year-old woman with low back pain and pain in both legs that was dominant on the right. Right lumbosacral nerve compression due to a massive uterine myoma was apparent, but the leg pain continued after a myomectomy was performed. No abnormalities were observed during nerve conduction studies. Computed tomography and magnetic resonance imaging indicated bilateral L5 lumbar foraminal stenosis. DTI imaging was done. The extraforaminal values were decreased and tractography was interrupted in the foraminal region. Bilateral L5 vertebral foraminal stenosis was treated by transforaminal lumbar interbody fusion and the pain in both legs disappeared. The case indicates the value of DTI for diagnosing vertebral foraminal stenosis.

A classification of growth friendly spine implants.
Skaggs, David L; Akbarnia, Behrooz A; Flynn, John M; Myung, Karen S; Sponseller, Paul D; Vitale, Michael G

Various types of spinal implants have been used with the objective of minimizing spinal deformities while maximizing the spine and thoracic growth in a growing child with a spinal deformity. The aim of this study was to describe a classification system of growth friendly spinal implants to allow researchers and clinicians to have a common language and facilitate comparative studies. Growth friendly spinal implant systems fall into 3 categories based upon the forces of correction the implants exert on the spine, which are as follows: Distraction-based systems correct spinal deformities by mechanically applying a distractive force across a deformed segment with anchors at the top and bottom of the implants, which commonly attach to the spine, rib, and/or the pelvis. The present examples of distraction-based implants are spine-based or rib-based growing rods, vertical expandable titanium rib prosthesis, and remotely expandable devices. Compression-based systems correct spinal deformities with a compressive force applied to the convexity of the curve causing convex growth inhibition. This compressive force may be generated both mechanically at the time of implantation, as well as over time resulting from longitudinal growth of vertebral endplates hindered by the spinal implants. Examples of compression-based systems are vertebral staples and tethers. Guided growth systems correct spinal deformity by anchoring multiple vertebrae (usually including the apical vertebrae) to rods with mechanical forces including translation at the time of the initial implant. The majority of the anchors are not rigidly attached to the rods, thus permitting longitudinal growth over time as the anchors slide over the rods. Examples of guided growth systems include the Luque trolley and Shilla. Each system has its benefits and shortcomings. Knowledge of the fundamental principles upon which these systems are based may aid the clinician to choose an appropriate treatment for patients. Having a common language for these systems may aid in comparative research. Vertical expandable titanium rib prosthesis is used with humanitarian exemption. The other devices mentioned in this manuscript are not approved for growing constructs by the Food and Drug Administration and are used off-label.

Bruck syndrome (BS) is a disorder characterized by joint flexion contractures and skeletal dysplasia that shows strong clinical overlap with the brittle bone disease Osteogenesis Imperfecta (OI). BS is caused by bi-allelic mutations in either the FKBP10 or the PLOD2 gene. PLOD2 encodes the lysyl hydroxylase 2 (LH2) enzyme, which is responsible for the hydroxylation of lysine residues in fibrillar collagen telopeptides. This hydroxylation directs cross-linking of collagen fibrils in the extracellular matrix, which is necessary to provide stability and tensile integrity to the collagen fibrils. To further elucidate the function of LH2 in vertebrate skeletal development, we created a zebrafish model harboring a homozygous plod2 nonsense mutation resulting in reduced telopeptide hydroxylation and cross-linking of bone type I collagen. Adult plod2 mutants present with a shortened body axis and severe skeletal abnormalities with evidence of bone fragility and fractures. The vertebral column of plod2 mutants is short and scoliotic with compressed vertebrae that show excessive bone formation at the vertebral end plates, and increased tissue mineral density in the vertebral centra. The muscle fibers of mutant zebrafish have a reduced diameter near the horizontal myoseptum. The endomysium, a layer of connective tissue ensheathing the individual muscle fibers, is enlarged. Transmission electron microscopy of mutant vertebral bone shows type I collagen fibrils that are less organized with loss of the typical plywood-like structure. In conclusion, plod2 mutant zebrafish show molecular and tissue abnormalities in the musculoskeletal system that are concordant with clinical findings in BS patients. Therefore, the plod2 zebrafish mutant is a promising model for the elucidation of the underlying pathogenetic mechanisms leading to BS and the development of novel therapeutic avenues in this syndrome.

Pathogenesis of lumbar spine disease in mucopolysaccharidosis VII

Mucopolysaccharidosis type VII (MPS VII) is characterized by deficient β-glucuronidase (GUSB) activity, which leads to accumulation of chondroitin, heparan and dermatan sulfate glycosaminoglycans (GAGs), and multisystemic disease. MPS VII patients can develop kypho-scoliotic deformity and spinal cord compression due to disease of intervertebral discs, vertebral bodies, and associated tissues. We have previously demonstrated in MPS VII dogs that intervertebral discs degenerate, vertebral bodies have irregular surfaces, and vertebral body epiphyses have reduced calcification, but the pathophysiological mechanisms underlying these changes are unclear. We hypothesized that some of these manifestations could be due to upregulation of destructive proteases, possibly via the binding of GAGs to Toll-like receptor 4 (TLR4), as has been proposed for other tissues in MPS models. In this study, the annulus fibrosus of the intervertebral disc of 6 month-old MPS VII dogs had cathepsin B and K activities that were 117- and 2-fold normal, respectively, which were associated with elevations in mRNA levels for cathepsins as well as TLR4. The epiphyses of MPS VII dogs had a marked elevation in mRNA for the cartilage-associated gene collagen II, consistent with a developmental delay in the conversion of the cartilage to bone in this region. A spine from a human patient with MPS VII exhibited similar increased cartilage in the vertebral bodies adjacent to the end plates, disorganization of the intervertebral discs, and irregular vertebral end plate morphology. These data suggest that the pathogenesis of destructive changes in the spine in MPS VII may involve upregulation of cathepsins. Inhibition of destructive proteases, such as cathepsins, might reduce spine disease in patients with MPS VII or related disorders. PMID:22513347

Cervical spondylomyelopathy (CSM), also known as wobbler syndrome, affects mainly large and giant-breed dogs, causing compression of the cervical spinal cord and/or nerve roots. Structural and dynamic components seem to play a role in the development of CSM; however, pathogenesis is not yet fully understood. Finite element models have been used for years in human medicine to study the dynamic behavior of structures, but it has been mostly overlooked in veterinary studies. To our knowledge, no specific ligamentous spine models have been developed to investigate naturally occurring canine myelopathies and possible surgical treatments. The goal of this study was to develop a finite element model (FEM) of the C 2 -C 7 segment of the ligamentous cervical vertebral column of a neurologically normal Great Dane without imaging changes. The FEM of the intact C 2 -C 7 cervical vertebral column had a total of 188,906 elements (175,715 tetra elements and 12,740 hexa elements). The range of motion (in degrees) for the FEM subjected to a moment of 2Nm was approximately 27.94 in flexion, 25.86 in extension, 24.14 in left lateral bending, 25.27 in right lateral bending, 17.44 in left axial rotation, and 16.72 in right axial rotation. We constructed a ligamentous FEM of the C 2 -C 7 vertebral column of a Great Dane dog, which can serve as a platform to be modified and adapted for studies related to biomechanics of the cervical vertebral column and to further improve studies on osseous-associated cervical spondylomyelopathy.

Maffucci syndrome is a nonhereditary disorder caused by somatic mosaic isocitrate dehydrogenase 1 or 2 (IDH1 or IDH2) mutations and is characterized by multiple enchondromas along with hemangiomas. Malignant transformation of enchondromas to chondrosarcomas and secondary neoplasms, such as brain tumors or acute myeloid leukemia, are serious complications. A 15-year-old female with Maffucci syndrome developed B-cell precursor acute lymphoblastic leukemia (BCP-ALL). A somatic mutation in IDH1 was detected in hemangioma and leukemic cells. KRAS mutation and deletion of IKZF1 were detected in leukemic cells. Patients with Maffucci syndrome may, therefore, be at risk of BCP-ALL associated with secondary genetic events that affect lymphocyte differentiation. © 2017 Wiley Periodicals, Inc.
STRAWBERRY HEMANGIOMAS—The Natural History of the Untreated Lesion
Jacobs, Alvin H.
1957-01-01
A review of the literature on the natural history of strawberry hemangiomas revealed over-whelming evidence of the satisfactory spontaneous involution of over 95 per cent of these lesions without the scarring and danger of other sequelae inherent in the various forms of treatment. In a study of 105 strawberry nevi observed for more than one year, 97 per cent of the lesions had either completely disappeared or were regressing satisfactorily. A cross-section study of 1,735 consecutively examined children in routine pediatric practice showed hemangiomas to be present in 10.1 per cent of all infants from birth to one year of age but that this incidence drops to 1.5 per cent in children over five years of age, confirming the fact of spontaneous involution.

Theobald, Anita; Dennis, Ruth; Beltran, Elsa
2014-01-01
A 4-year-old, spayed female greyhound dog was presented with an acute onset of paraplegia. There was no known history of trauma or coagulopathy. Spinal cord compression was identified on MRI. Intra-operative evaluation revealed the presence of a large subperiosteal hematoma and a smaller epidural hematoma. To the authors' knowledge, this is the first report of a spinal subperiosteal hematoma diagnosed antemortem through MRI, with surgical exploration and successful treatment in a dog. © 2013 American College of Veterinary Radiology.
Osteopenia and bone fractures in a man with anorexia nervosa and hypogonadism

Rigotti, N.A.; Neer, R.M.; Jameson, L.
Women with anorexia nervosa have reduced skeletal mass. Both anorexia and osteopenia are less common in men. We describe a 22-year-old man with anorexia nervosa and severe osteopenia involving both cortical and trabecular bone who developed a pelvic fracture and multiple vertebral compression fractures. He was found to have secondary hypogonadotropic hypogonadism that was reversible with weight gain. This case illustrates the need to consider osteopenia as a potential complication of anorexia nervosa in males as well as females.

Introduction Mucopolysaccharidosis I (MPS I) is a lysosomal storage disorder characterized by deficient α-L-iduronidase activity leading to accumulation of poorly degraded dermatan and heparan sulfate glycosaminoglycans (GAGs). MPS I is associated with significant cervical spine disease, including vertebral dysplasia, odontoid hypoplasia, and accelerated disc degeneration, leading to spinal cord compression and kypho-scoliosis. The objective of this study was to establish the nature and rate of progression of cervical vertebral bone disease in MPS I using a canine model. Methods C2 vertebrae were obtained post-mortem from normal and MPS I dogs at 3, 6 and 12 months-of-age. Morphometric parameters and mineral density for the vertebral trabecular bone and odontoid process were determined using micro-computed tomography. Vertebrae were then processed for paraffin histology, and cartilage area in both the vertebral epiphyses and odontoid process were quantified. Results Vertebral bodies of MPS I dogs had lower trabecular bone volume/total volume (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N) and bone mineral density (BMD) than normals at all ages. For MPS I dogs, BV/TV, Tb.Th and BMD plateaued after 6 months-of-age. The odontoid process appeared morphologically abnormal for MPS I dogs at 6 and 12 months-of-age, although BV/TV and TMD were not significantly different from normals. MPS I dogs had significantly more cartilage in the vertebral epiphyses at both 3 and 6 months-of-age. At 12 months-of-age, epiphyseal growth plates in normal dogs were absent, but in MPS I dogs they persisted. Conclusions In this study we report reduced trabecular bone content and mineralization, and delayed cartilage to bone conversion in MPS I dogs from 3 months-of-age, which may increase vertebral fracture risk and contribute to progressive deformity. The abnormalities of the odontoid process we describe likely contribute to increased incidence of atlanto-axial subluxation observed clinically. Therapeutic strategies that enhance bone formation may decrease incidence of spine disease in MPS I patients. PMID:23563357

A case-control study. In this study, we investigated the correlation between level-specific preoperative bone mineral density and subsequent vertebral fractures. We also identified factors associated with subsequent vertebral fractures. Complications of cement augmentation of the spine include subsequent vertebral fractures, leading to unnecessary morbidity and more treatment. Ability to predict at-risk vertebra will help guide management. We studied all patients with osteoporotic compression fractures who underwent cement augmentation in a single institution from November 2001 to December 2010 by a single surgeon. Association between level-specific bone mineral density T-scores and subsequent fractures was assessed. Multivariable analysis was performed to identify significant factors associated with subsequent vertebral fractures. 93 patients followed up for a mean duration of 25.1 months (12-96) had a mean age of 76.8 years (47-99). Vertebroplasty was performed in 58 patients (62.4%) on 68 levels and kyphoplasty in 35 patients (37.6%) on 44 levels. Refracture was seen in 16 patients (17.2%). The time to subsequent fracture post cement augmentation was 20.5 months (2-90). For refracture cases, 43.8% (7/16) fractured in the adjacent vertebrae. Subsequently fractured vertebra had a mean T-score of -2.860 (95% confidence interval -3.268 to -2.452) and nonfractured vertebra had a mean T-score of -2.180 (95% confidence interval -2.373 to -1.986). A T-score of -2.2 or lower is predictive of refracture at that vertebra (P = 0.047). Odds ratio increases with decreasing T-scores from -2.2 or lower to -2.6 or lower. A T-score of -2.6 or lower gives no additional predictive advantage. After multivariable analysis, age (P = 0.049) and loss of preoperative anterior vertebral height (P = 0.017) are associated with refracture. Level-specific T-scores are predictive of subsequent fractures and the odds ratio increases with lower T-scores from -2.2 or less to -2.6 or less. They have a low positive predictive value, but a high negative predictive value for subsequent fractures. Other significant associations with subsequent refractures include age and anterior vertebral height. 4.

Since 2014, cases of hemangioma associated with avian leukosis virus subgroup J (ALV-J) have been emerging in commercial chickens in Guangxi. In this study, four strains of the subgroup J avian leukosis virus (ALV-J), named GX14HG01, GX14HG04, GX14LT07, and GX14ZS14, were isolated from chickens with clinical hemangioma in 2014 by DF-1 cell culture and then identified with ELISA detection of ALV group specific antigen p27, the detection of subtype specific PCR and indirect immunofluorescence assay (IFA) with ALV-J specific monoclonal antibody. The complete genomes of the isolates were sequenced and it was found that the gag and pol were relatively conservative, while env was variable especially the gp85 gene. Homology analysis of the env gene sequences showed that the env gene of all the four isolates had higher similarities with the hemangioma (HE)-type reference strains than that of the myeloid leukosis (ML)-type strains, and moreover, the HE-type strains' specific deletion of 205-bp sequence covering the rTM and DR1 in 3'UTR fragment was also found in the four isolates. Further analysis on the sequences of subunits of env gene revealed an interesting finding: the gp85 of isolates GX14ZS14 and GX14HG04 had a higher similarity with HPRS-103 and much lower similarity with the HE-type reference strains resulting in GX14ZS14, GX14HG04, and HPRS-103 being clustered in the same branch, while gp37 had higher similarities with the HE-type reference strains when compared to that of HPRS-103, resulted in GX14ZS14, GX14HG04, and HE-type reference strains being clustered in the same branch. The results suggested that isolates GX14ZS14 and GX14HG04 may be the recombinant strains of the foreign strain HPRS-103 with the local epidemic HE-type strains of ALV-J.

Two 15-yr-old grizzly bear littermates were evaluated within 9 mo of each other with the symptom of acute onset of progressive paraparesis and proprioceptive ataxia. The most significant clinical examination finding was pelvic limb paresis in both bears. Magnetic resonance examinations of both bears showed cranial thoracic spinal cord compression. The first bear had left-sided extradural, dorsolateral spinal cord compression at T3-T4. Vertebral canal stenosis was also observed at T2-T3. Images of the second bear showed lateral spinal cord compression from T2-T3 to T4-T5. Intervertebral disk disease and associated spinal cord compression was also observed at T2-T3 and T3-T4. One grizzly bear continued to deteriorate despite reduced exercise, steroid, and antibiotic therapy. The bear was euthanized, and a necropsy was performed. The postmortem showed a spinal ganglion cyst that caused spinal cord compression at the level of T3-T4. Wallerian-like degeneration was observed from C3-T6. The second bear was prescribed treatment that consisted of a combination of reduced exercise and steroid therapy. He continued to deteriorate with these medical therapies and was euthanized 4 mo after diagnosis. A necropsy showed hypertrophy and protrusion of the dorsal longitudinal ligament at T2-T3 and T3-T4, with resulting spinal cord compression in this region. Wallerian-like degeneration was observed from C2-L1. This is one of few case reports that describes paresis in bears. It is the only case report, to the authors' knowledge, that describes spinal magnetic resonance imaging findings in a grizzly bear and also the only report that describes a cranial thoracic myelopathy in two related grizzly bears with neurologic signs.

Background: The cross-section of thoracolumbar vertebral body is kidney-shaped with depressed posterior boundary. The anterior wall of the vertebral canal is separated from the posterior wall of the vertebral body on the lateral X-ray image. This study was designed to determine the sagittal distance between the anterior border of the vertebral canal and the posterior border of the vertebral body (DBCV) and to analyze the potential role of DBCV in the estimation of cement leakage during percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). Methods: We retrospectively recruited 233 patients who had osteoporotic vertebral compression fractures and were treated with PVP or PKP. Computed tomography images of T11–L2 normal vertebrae were measured to obtain DBCV. The distance from cement to the posterior wall of the vertebral body (DCPW) of thoracolumbar vertebrae was measured from C-arm images. The selected vertebrae were divided into two groups according to DCPW, with the fracture levels, fracture grades and leakage rates of the two groups compared. A relative operating characteristic (ROC) curve was applied to determine whether the DCPW difference can be used to estimate the degree of cement leakage. The data were processed by statistical software SPSS version 21.0 using independent sample t-test and Chi-square tests. Results: The maximum DBCV was 6.40 mm and the average DBCV was 3.74 ± 0.95 mm. DBCV appeared to be longer in males than in females, but the difference was not statistically significant. The average DCPW of type-B leakage vertebrae (2.59 ± 1.20 mm) was shorter than that of other vertebrae (7.83 ± 2.38 mm, P < 0.001). The leakage rate of group DCPW ≤6.40 mm was lower than that of group DCPW >6.40 mm for type-C and type-S, but much higher for type-B. ROC curve revealed that DCPW only has a predictive value for type-B leakage (area under the curve: 0.98, 95% confidence interval: 0.95–0.99, P < 0.001), and when the cut-off value was 4.05 mm, the diagnostic sensitivity and the specificity were 94.87% and 93.02%, respectively. Conclusions: Depression of the thoracolumbar posterior vertebral body may be informative for the estimation of cement location on C-arm images. To reduce type-B leakage, DCPW should be made longer than DBCV on C-arm images for safety during PVP or PKP. PMID:26612289

[Mechanical studies of lumbar interbody fusion implants].

In addition to autogenous or allogeneic bone grafts, fusion cages composed of metal or plastic are being used increasingly as spacers for interbody fusion of spinal segments. The goal of this study was the mechanical testing of carbon fiber reinforced plastic (CFRP) fusion cages used for anterior lumbar interbody fusion. With a special testing device according to American Society for Testing and Materials (ASTM) standards, the mechanical properties of the implants were determined under four different loading conditions. The implants (UNION cages, Medtronic Sofamor Danek) provide sufficient axial compression, shear, and torsional strength of the implant body. Ultimate axial compression load of the fins is less than the physiological compression loads at the lumbar spine. Therefore by means of an appropriate surgical technique parallel grooves have to be reamed into the endplates of the vertebral bodies according to the fin geometry. Thereby axial compression forces affect the implants body and the fins are protected from damaging loading. Using a supplementary anterior or posterior instrumentation, in vivo failure of the fins as a result of physiological shear and torsional spinal loads is unlikely. Due to specific complications related to autogenous or allogeneic bone grafts, fusion cages made of metal or carbon fiber reinforced plastic are an important alternative implant in interbody fusion.

The mechanical strength properties of lumbar spine vertebrae are of great importance in a wide range of applications. Herein, through nanoindentations and appropriate evaluation of the corresponding results, trabecular bone struts stress-strain characteristics can be determined. In the frame of the present paper, an L2 fresh cadaveric vertebra, from which posterior elements were removed, was subjected to compression. With the aid of developed finite elements method based algorithms, the cortical shell and the cancellous core bulk elasticity moduli and stresses were determined, whereas the tested vertebra geometrical model used in these algorithms was considered as having a compound structure, consisting of the cancellous bone surrounded by the cortical shell. Moreover nanoindentations were conducted and an appropriate evaluation method of the obtained results was applied to extract stress-strain curves of individual lumbar spine vertebra trabecular bone struts. These data were used in the mathematical description of the vertebrae compression test. The vertebral cancellous bone structure was simulated by a beam elements network, possessing an equivalent porosity and different stiffnesses in vertical and horizontal direction. Thus, the measured course of the compression load versus the occurring specimen deformation was verified.

The First Korean Case of Cutaneous Lung Tissue Heterotopia
Jeon, Ga Won; Han, Seong Woo; Jung, Ji Mi; Kang, Mi Seon
2010-01-01
Cutaneous lung tissue heterotopia is a very rare disorder where mature lung tissues develop in the skin. This is only the second known report of cutaneous lung tissue heterotopia, with the first by Singer et al. in 1998. A newborn infant had a hemangioma-like, freely movable mass connected to the anterior aspect of the sternal manubrium. Pathologic findings showed mature lung tissues with bronchi, bronchioles, and alveoli through the dermis and subcutis, and it was diagnosed as cutaneous lung tissue heterotopia. Cutaneous lung tissue heterotopia is hypervascular, so grossly it looks like a hemangioma. It can be differentiated from pulmonary sequestration, teratoma, bronchogenic cyst, and branchial cleft cyst by histology and the location of the mass. We describe the clinical, radiologic, and pathologic findings of a cutaneous lung tissue heterotopia, the first reported in Korea. PMID:20808688

A 26-year-old woman (G2P1A1) presented with a 5-week history of multiple red marks on her body after a therapeutic abortion. A physical examination found 15 palpable red marks on her head, neck, chest, arms and legs. Proliferating endothelial cells, which expressed CD31, CD34, von Willebrand factor, but not Glut-1 and merosin, were observed in the lesional area by histopathological analyses. Histocompatibility antigen typing of 2 lesions was identical to a sample from peripheral blood. Accelerated regression was observed in 2 lesions treated by intralesional injection of betamethasone, while spontaneous regression was observed within 9 months in the remaining lesions without any treatment. Rapid growth, spontaneous regression and histological analyses in this case support the diagnosis of 'infantile hemangioma-like vascular lesion'.

Study Design Case study. Objectives We report the case of a 58-year-old Caucasian man, who presented with a 4-month history of increasing low back pain and gait difficulty. Objective neurologic examination revealed a severe paraparetic symptomatology without any sphincter involvement. Methods Spinal magnetic resonance imaging (MRI) showed an extradural mass formation situated dorsally at the level of thoracic vertebrae T2 to T4. Results A laminectomy was performed with total removal of the mass; histology suggested a highly vascularized lesion with lobular architecture, which seems a very rare case, compatible with a capillary hemangioma. Conclusions A careful follow-up for the next 4 years, including control MRIs every postoperative year, showed a very good neurologic condition of the patient and no recurrence on imaging findings.

Infantile hemangioma (IH) is the most frequent benign tumor of infancy resulting from vascular proliferation. Data regarding the burden on families of children with IHs are limited. This study aimed to characterize IHs and provide a comprehensive evaluation of the burden of IHs on parents of children requiring systemic treatment in the United States and Europe. This noninterventional cross-sectional study included infants with newly diagnosed IH requiring systemic treatment. A parent or family member completed two questionnaires (Family Member questionnaire; Hemangioma Family Burden [HFB] questionnaire). A total of 693 individuals were evaluable in five countries. IHs were observed in more girls than boys (66%-83% female) and the mean age at inclusion was 0.44 to 1.4 years. Approximately half of patients had superficial IHs, approximately 70% of cases affected the head, and approximately 80% of cases were moderate or severe. Most patients received propranolol treatment. Their child's IH affected more than 70% of parents in each country, but fewer than 10% were offered psychological support. Approximately half of all parents reported that their child's IH affected their professional life. The global HFB score was significantly (p < 0.001) greater with greater IH severity. More than 90% of parents in each country were satisfied with the care of their child's disease. This international study using the validated HFB questionnaire provides further insight into the burden of IH and highlights potential areas for future focus in assisting families with affected children. © 2017 Wiley Periodicals, Inc.

Osteoporotic vertebral fractures (OVF) can lead to late collapse which often causes kyphotic spinal deformity, persistent back pain, decreased lung capacity, increased fracture risk and increased mortality. The purpose of our study is to compare the efficacy and safety of vertebroplasty against conservative management of osteoporotic vertebral fractures without neurologic symptoms. A total of 66 patients with recent OVF on MRI examination were included in the study. All patients were admitted from September 2009 to September 2012. The cohort was divided into two groups. The first study group consisted of 33 prospectively followed consecutive patients who suffered 40 vertebral osteoporotic fractures treated by percutaneous vertebroplasty (group 1), and the control group consisted of 33 patients who suffered 41 vertebral osteoporotic fractures treated conservatively because they refused vertebroplasty (group 2). The data collection has been conducted in a prospective registration manner. The inclusion criteria consisted of painful OVF matched with imagistic findings. We assessed the results of pain relief and minimal sagittal area of the vertebral body on the axial CT scan at presentation, after the intervention, at six and 12 months after initial presentation. Vertebroplasty with poly(methyl methacrylate) (PMMA) was performed in 30 patients on 39 VBs, including four thoracic vertebras, 27 vertebras of the thoracolumbar jonction and eight lumbar vertebras. Group 2 included 30 patients with 39 OVFs (four thoracic vertebras, 23 vertebras of the thoracolumbar junction and 11 lumbar vertebras). There was no significant difference in VAS scores before treatment (p = 0.229). The mean VAS was 5.90 in Group 1 and 6.28 in Group 2 before the treatment. Mean VAS after vertebroplasty was 0.85 in Group 1. The mean VAS at six months was 0.92 in Group 1 and 3.00 in Group 2 (p < 0.05). The mean VAS at 12 months was 0.92 in Group 1 and 2.36 in Group 2. The mean improvement rate in VAS scores was 84.40% and 62.42%, respectively (p < 0.05). For Group 1, mean area of the VBs measured on sagital CT images was 8.288 at the initial presentation, 8.554 postoperatively, 8.541 at five months and 8.508 at 12 months, respectively, and 8.388 at the initial presentation, 7.976 at six months and 7.585 at 12 months for Group 2 (Fig. 4). Although conservative treatment is fundamental and achieves good symptom control, in patients who suffer osteoporotic compression fractures (OCF), the incidence of late collapse is high and the prognosis is poor. In order to relieve the pain and avoid VB collapse, vertebroplasty is the recommended treatment in OCFs. Considering the above findings, the dilemma is whether vertebroplasty can change the natural history (pain and deformity) of OCFs. In our study on OVF, vertebroplasty delivered superior clinical and radiological outcomes over the first year from intervention when compared to conservative treatment of patients with osteoporotic compression fractures without neurological deficit. We believe that the possibility of evolution towards progressive kyphosis is sufficient to justify prophylactic and therapeutic intervention such as vertebroplasty, a minor gesture compared with extensive correction surgery and stabilization.

CT scanning of ancient human remains has the potential to provide insights into health and diseases. While Egyptian mummies have undergone CT scans in prior studies, a systematic survey of the orthopedic conditions afflicting a group of these ancient individuals has never been carried out. We performed whole body CT scanning on 52 ancient Egyptian mummies using technique comparable to that of medical imaging. All of the large joints and the spine were systematically examined and osteoarthritic (OA) changes were scored 0-4 using Kellgren and Lawrence classification. The cruciate ligaments and menisci could be identified frequently. There were much more frequent OA changes in the spine (25 mummies) than in the large joints (15 cases of acromioclavicular and/or glenohumeral joint OA changes, five involvement of the ankle, one in the elbow, four in the knee, and one in the hip). There were six cases of scoliosis. Individual mummies had the following conditions: juvenile aseptic necrosis of the hip (Perthes disease), stage 4 osteochondritis dissecans of the knee, vertebral compression fracture, lateral patella-femoral joint hyper-compression syndrome, severe rotator cuff arthropathy, rotator cuff impingement, hip pincer impingement, and combined fracture of the greater trochantor and vertebral bodies indicating obvious traumatic injury. This report includes the most ancient discovery of several of these syndromes. Ancient Egyptians often suffered painful orthopedic conditions. The high frequency of scoliosis merits further study. The pattern of degenerative changes in the spine and joints may offer insights into activity levels of these people. © 2015 Wiley Periodicals, Inc.

Patients diagnosed with bone metastases secondary to breast, prostate or lung cancer were included in this multicentre, observational study. SREs are defined as pathologic fracture (vertebral and non-vertebral fracture), radiation to bone, spinal cord compression or surgery to bone. Health resource utilisation associated with these events (inpatient stays, outpatient, emergency room and home health visits, nursing home stays and procedures) were collected retrospectively for all SREs that occurred in the 97 days prior to enrolment and prospectively during follow-up. Unit costs were obtained from the 2010 eSalud healthcare costs database. A total of 93 Spanish patients with solid tumours were included (31 had breast cancer, 21 prostate cancer and 41 lung cancer), contributing a total of 143 SREs to this cost analysis. Inpatient stays (between 9.0 and 29.9 days of mean length of stay per inpatient stay by SRE type) and outpatient visits (between 1.7 and 6.4 mean visits per SRE type) were the most frequently reported types of health resources utilised. The mean cost per SRE was between

We report on vascular compression syndrome of the 12th cranial nerve (hypoglossal), an occurrence not previously reported, and demonstrate, through corresponding objective electrophysiological evidence, that microvascular decompression of the hypoglossal nerve root can cure hemilingual spasm. A 52-year-old man had lower face muscle twitching and tongue spasms, which worsened with talking, chewing, or emotional stress. Carbamazepine offered only temporary relief, and relief from injections of botulinum toxin was insignificant. He was referred for surgical treatment. High-resolution magnetic resonance imaging of his posterior fossa contents revealed no obvious evidence of any compressive vessel along the facial nerve, but a compressive vessel along the hypoglossal nerve was apparent. The presence of preoperative tongue spasms encouraged interoperative monitoring of tongue motor responses. The facial nerve exit zone was explored, but microsurgical inspection of the seventh/eighth cranial nerve complex did not reveal any compressive vessel. However, at the anterolateral aspect of the medulla oblongata, the hypoglossal nerve was clearly compressed and distorted laterally by a large tortuous vertebral artery. When the artery was mobilized away from the nerve, the abnormal late electromyographic response to transcranial electrical stimulation disappeared; immediately after shredded Teflon was interpositioned between the artery and the nerve, the abnormal spontaneous tongue fasciculation also disappeared. The patient has remained spasm free 6 months after surgery. Hemilingual spasm may be caused by vascular contact/compression along cranial nerve XII at the lower brainstem and belong to the same family of cranial nerve hyperactivity disorders as hemifacial spasm.

Gas gangrene is most often caused by Clostridium perfringens infection. Gas gangrene is a medical emergency that develops suddenly. The mortality rate is higher with trunk involvement than with involvement of the extremities, which carries a better prognosis. With respect to vertebral involvement, there are few reports in the literature. The purpose of this paper is to report a very rare case of vertebral osteomyelitis caused by gas gangrene. A 78-year-old Japanese woman with diabetes mellitus was admitted to our hospital with the chief complaints of back pain, dysuria, and complete paralysis of both legs. A computed tomography scan showed soft tissue swelling anterolaterally at intervertebral disc level T11/12 and a gas-containing epidural abscess that compressed her spinal cord. Cultures later grew Clostridium perfringens and Escherichia coli. Hemilaminectomy was done from T10 to T12, and an epidural abscess was removed. She went on to have fusion surgery 6 weeks after the initial operation and subsequently experienced complete pain relief. She was discharged 2 months later, at which time she was able to walk with a cane. Examination 18 months after surgery showed normal gait without a cane. Discitis caused by gas gangrene infection was successfully treated by immediate debridement and subsequent fusion surgery.

To investigate the effect of a porous calcium phosphate/bone matrix gelatin (BMG) composite cement (hereinafter referred to as the "porous composite cement") for repairing lumbar vertebral bone defect in a rabbit model. BMG was extracted from adult New Zealand rabbits according to the Urist's method. Poly (lactic-co-glycolic) acid (PLGA) microsphere was prepared by W/O/W double emulsion method. The porous composite cement was developed by using calcium phosphate cement (CPC) composited with BMG and PLGA microsphere. The physicochemical characterizations of the porous composite cement were assessed by anti-washout property, porosity, and biomechanical experiment, also compared with the CPC. Thirty 2-month-old New Zealand rabbits were used to construct vertebral bone defect at L 3 in size of 4 mm×3 mm×3 mm. Then, the bone defect was repaired with porous composite cement (experimental group, n =15) or CPC (control group, n =15). At 4, 8, and 12 weeks after implantation, each bone specimen was assessed by X-ray films for bone fusion, micro-CT for bone mineral density (BMD), bone volume fraction (BVF), trabecular thickness (Tb. Th.), trabecular number (Tb.N.), and trabecular spacing (Tb. Sp.), and histological section with toluidine blue staining for new-born bone formation. The study demonstrated well anti-washout property in 2 groups. The porous composite cement has 55.06%±1.18% of porosity and (51.63±6.73) MPa of compressive strength. The CPC has 49.38%±1.75% of porosity and (63.34±3.27) MPa of compressive strength. There were significant differences in porosity and compressive strength between different cements ( t =4.254, P =0.006; t =2.476, P =0.034). X-ray films revealed that the zone between the cement and host bone gradually blurred with the time extending. At 12 weeks after implantation, the zone was disappeared in the experimental group, but clear in the control group. There were significant differences in BMD, BVF, Tb. Th., Tb. N., and Tb. Sp. between 2 groups at each time point ( P <0.05). Histological observation revealed that there was new-born bone in the cement with the time extending in 2 groups. Among them, bony connection was observed between the new-born bone and the host in the experimental group, which was prior to the control group. The porous composite cement has dual bioactivity of osteoinductivity and osteoconductivity, which are effective to promote bone defect healing and reconstruction.

Vertebral compression fractures (VCFs) are one of the most common injuries in the aging population presenting with an annual incidence of 1.4 million new cases in Europe. Current treatment strategies focus on cement-associated solutions (kyphoplasty/vertebroplasty techniques). Specific cement-associated problems as leakage, embolism and the adjacent fracture disease are reported adding to open questions like general fracture healing properties of the osteoporotic spine. In order to analyze those queries animal models are of great interest; however, both technical difficulties in the induction of experimental osteoporosis in animal as well as the lack of a standardized fracture model impede current and future in vivo studies. This study introduces a standardized animal model of an osteoporotic VCF type A3.1 that may enable further in-depth analysis of the afore mentioned topics. Twenty-four 5-year-old female Merino sheep (mean body weight: 67 kg; range 57-79) were ovariectomized (OP1) and underwent 5.5 months of weekly corticosteroid injections (dexamethasone and dexamethasone-sodium-phosphate), adding to a calcium/phosphorus/vitamin D-deficient diet. Osteoporosis induction was documented by pQCT and micro-CT BMD (bone mineral density) as well as 3D histomorphometric analysis postoperatively of the sheep distal radius and spine. Non osteoporotic sheep served as controls. Induction of a VCF of the second lumbar vertebra was performed via a mini-lumbotomy surgical approach with a standardized manual compression mode (OP2). PQCT analysis revealed osteoporosis of the distal radius with significantly reduced BMD values (0.19 g/cm(3), range 0.13-0.22 vs. 0.27 g/cm(3), range 0.23-0.32). Micro-CT documented significant lowering of BMD values for the second lumbar vertebrae (0.11 g/cm(3), range 0.10-0.12) in comparison to the control group (0.14 g/cm(3), range 0.12-0.17). An incomplete burst fracture type A3.1 was achieved in all cases and resulted in a significant decrease in body angle and vertebral height (KA 4.9°, range: 2-12; SI 4.5%, range: 2-12). With OP1, one minor complication (lesion of small bowel) occurred, while no complications occurred with OP2. A suitable spinal fracture model for creation of VCFs in osteoporotic sheep was developed. The technique may promote the development of improved surgical solutions for VCF treatment in the experimental and clinical setting. Copyright © 2015 Elsevier Ltd. All rights reserved.

OBJECTIVE Spine radiosurgery is increasingly being used to treat spinal metastases. As patients are living longer because of the increasing efficacy of systemic agents, appropriate follow-up and posttreatment management for these patients is critical. Tumor progression after spine radiosurgery is rare; however, vertebral compression fractures are recognized as a more common posttreatment effect. The use of radiographic imaging alone posttreatment may makeit difficult to distinguish tumor progression from postradiation changes such as fibrosis. This is the largest series from a prospective database in which the authors examine histopathology of samples obtained from patients who underwent surgical intervention for presumed tumor progression or mechanical pain secondary to compression fracture. The majority of patients had tumor ablation and resulting fibrosis rather than tumor progression. The aim of this study was to evaluate tumor histopathology and characteristics of patients who underwent pathological sampling because of radiographic tumor progression, fibrosis, or collapsed vertebrae after receiving high-dose single-fraction stereotactic radiosurgery. METHODS Between January 2005 and January 2014, a total of 582 patients were treated with linear accelerator-based single-fraction (18-24 Gy) stereotactic radiosurgery. The authors retrospectively identified 30 patients (5.1%) who underwent surgical intervention for 32 lesions with vertebral cement augmentation for either mechanical pain or instability secondary to vertebral compression fracture (n = 17) or instrumentation (n = 15) for radiographic tumor progression. Radiation and surgical treatment, histopathology, and long-term outcomes were reviewed. Survival and time to recurrence were calculated using the Kaplan-Meier method. RESULTS The mean age at the time of radiosurgery was 59 years (range 36-80 years). The initial pathological diagnoses were obtained for all patients and primarily included radioresistant tumor types, including renal cell carcinoma in 7 (22%), melanoma in 6 (19%), lung carcinoma in 4 (12%), and sarcoma in 3 (9%). The median time to surgical intervention was 24.7 months (range 1.6-50.8 months). The median follow-up and overall survival for all patients were 42.5 months and 41 months (overall survival range 7-86 months), respectively. The majority of assessed lesions showed no evidence of tumor on pathological review (25 of 32, 78%), while a minority of lesions revealed residual tumor (7 of 32, 22%). The median survival for patients after tumor recurrence was 5 months (range 2-70 months). CONCLUSIONS High-dose single-fraction radiosurgery is tumor ablative in the majority of instances. In a minority of cases, tumor persists and salvage treatments should be considered.

A fully automated segmentation algorithm, progressive surface resolution (PSR), is presented in this paper to determine the closed surface of approximately convex blob-like structures that are common in biomedical imaging. The PSR algorithm was applied to the cortical surface segmentation of 460 vertebral bodies on 46 low-dose chest CT images, which can be potentially used for automated bone mineral density measurement and compression fracture detection. The target surface is realized by a closed triangular mesh, which thereby guarantees the enclosure. The surface vertices of the triangular mesh representation are constrained along radial trajectories that are uniformly distributed in 3D angle space. The segmentation is accomplished by determining for each radial trajectory the location of its intersection with the target surface. The surface is first initialized based on an input high confidence boundary image and then resolved progressively based on a dynamic attraction map in an order of decreasing degree of evidence regarding the target surface location. For the visual evaluation, the algorithm achieved acceptable segmentation for 99.35 % vertebral bodies. Quantitative evaluation was performed on 46 vertebral bodies and achieved overall mean Dice coefficient of 0.939 (with max [Formula: see text] 0.957, min [Formula: see text] 0.906 and standard deviation [Formula: see text] 0.011) using manual annotations as the ground truth. Both visual and quantitative evaluations demonstrate encouraging performance of the PSR algorithm. This novel surface resolution strategy provides uniform angular resolution for the segmented surface with computation complexity and runtime that are linearly constrained by the total number of vertices of the triangular mesh representation.

To report the clinical presentation, imaging characteristics, treatment results, and histopathological findings of a previously undescribed vertebral malformation in the Basset Hound. Retrospective case series study. Eighteen Basset Hounds presented for evaluation of a suspected cervical spinal cord problem. All dogs underwent computed tomography myelography or magnetic resonance imaging of the cervical region. Thirteen male and 5 female Basset Hounds between 6 months and 10.8 years of age (median: 1.4 years) were studied. Clinical signs varied from cervical hyperesthesia to nonambulatory tetraparesis. Imaging demonstrated a well-defined and smooth hypertrophy of the dorsal lamina and spinous process of ≥ 2 adjacent vertebrae. Although this bony abnormality could decrease the ventrodorsal vertebral canal diameter, dorsal midline spinal cord compression was predominantly caused by ligamentum flavum hypertrophy. The articulation between C4 and C5 was most commonly affected. Three dogs were lost to follow-up, 10 dogs underwent dorsal laminectomy, and medical management was initiated in 5 dogs. Surgery resulted in a good outcome with short hospitalization times (median: 4.5 days) in all dogs, whereas medical management produced more variable results. Histopathology confirmed ligamentum flavum hypertrophy and demonstrated the fibrocartilaginous nature of this anomaly. Dorsal lamina and spinous process hypertrophy leading to ligamentum flavum hypertrophy should be included in the differential diagnosis of Basset Hounds with cervical hyperesthesia or myelopathy. Prognosis after decompressive surgery is favorable. Although a genetic component is suspected, additional studies are needed to determine the specific etiology of this disorder.

Kyphoplasty has been widely used to treat vertebral compression fractures (VCFs). In standard procedure of kyphoplasty, two balloons were inserted into the vertebral body through bipedicular and inflated simultaneously, while using a single balloon two times is also a common method in clinic to lessen the financial burden of patients. However, the effect and safety of single balloon versus double balloon bipedicular kyphoplasty are still controversy. In this systematic review and meta-analysis, eligible studies were identified through a comprehensive literature search of PubMed, Cochrane library EMBASE, Web of Science, Wanfang, CNKI, VIP and CBM until January 1, 2018. Results from individual studies were pooled using a random or fixed effects model. Seven articles were included in the systematic review and five studies were consisted in meta-analysis. We observed no significant difference between single balloon and double balloon bipedicular kyphoplasty in visual analog scale (VAS), angle (kyphotic angle and Cobb angle), consumption (operation time, cement volume and volume of bleeding), vertebral height (anterior height, medium height and posterior height) and complications (cement leakage and new VCFs), while the cost of single balloon bipedicular kyphoplasty is lower than that of double balloon bipedicular kyphoplasty. The results of our meta-analysis also demonstrated that single balloon can significantly improve the VAS, angle and vertebral height of patients suffering from VCFs. This systematic review and meta-analysis collectively concludes that single balloon bipedicular kyphoplasty is as effective as double balloon bipedicular kyphoplasty in improving clinical symptoms, deformity and complications of VCFs but not so expensive.
