    Introduction: Simple bone cyst or unicameral bone cyst (UBC) are benign cystic lesions commonly found in femur and humerus. However hand is a very rare site of occurrence. Treatment described for UBC of hand commonly involves curettage and bone grafting. Case Report: A 7 year old right hand dominant girl presented to us with chief complaints of pain and swelling in right 4th metacarpal since 2 month. On imaging, plain radiographs of right hand showed expansile lytic lesion on Metaphyseal-diaphyseal region of 4th metacarpal with pathological fracture. MRI showed cystic lesions with internal loculations and fluid-fluid levels (Fig 2). There was minimal soft tissue extension. We performed aspiration which showed serosanguinous fluid with haemorrhagic tinge. With the diagnosis of unicameral bone cyst in mind we performed and closed intramedullary nail with k wire. The cyst healed up completely within 2 months. There was no recurrence at 18 month follow up. Conclusion: In conclusion simple bone cyst is very rare in metacarpal bone. However it should be considered as important differential since it warrants simple treatment and extensive procedures should be avoided. PMID:27298987

    This study was performed between 2007-2012 and encompasses 94 patients. The patients were divided in two groups. The first group included the patients who have benefited from surgical treatment (42 cases) and the second one included patients who benefited from conservative treatment. Out of the total number of cases, 63 cases showed an intact simple bone cyst that was most of the time an accidental discovery. 31 patients presented with fracture sustained on a simple bone cyst. There were 63 boys and 31 girls. Their mean age was 9.9 +/- 2.34 years. Single injection was performed for 49 patients; the rest had double or triple injections. The mean follow-up was 34.5 +/- 6.6 months. The procedure succeeded in obtaining healing in 77 cysts (82%). Cyst index of more than five and cortical index of less than 1 mm were significantly prone to pathological fractures and had significant poor results after treatment. Our results suggested that an autogenous bone marrow injection is a safe and effective treatment method for simple bone cysts, when compared with the surgical management, but sometimes-repeated injections are necessary. Cyst index and cortical width are good indicators for treatment outcome. PMID:23346253

    Simple bone cysts were treated by trepanation. The technique consists of drainage of cyst fluid, lavage of the cystic cavity with saline, and the making of multiple drilling holes through the cortical and the medullary bone of the cyst wall. Injection of corticosteroid was omitted. In 11 cases treated by this method, the clinical outcome was good. Biochemical analyses of the cyst fluid showed bone-resorptive factors, i.e., prostaglandins, interleukin 1, proteolytic enzymes. Electrophoretic analysis of proteolytic enzymes in polyacrylamide gel containing sodium dodecyl sulfate and polymerized gelatin showed proteins with molecular weights of about 130,000, 92,000, 72,000, and lower than 50,000. Increase in such bone-resorbing activities seems to be one of the causative factors in simple bone cysts. The technique was effective in decompressing the internal pressure of the cysts, improving the blood flow through the medullary bone of the cyst wall, stimulating the periosteum to induce bone formation, and eliminating bone destruction.

  4. Bone cysts: unicameral and aneurysmal bone cyst.

    Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion. ABCs are metaphyseal, excentric, bulging, fluid-filled and multicameral, and may develop in all bones of the skeleton. On MRI, the fluid level is evocative. It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. Treatment in non-threatening forms consists in intracystic injection of methylprednisolone. When there is a risk of fracture, especially of the femoral neck, surgery with curettage, filling with bone substitute or graft and osteosynthesis may be required. ABCs are potentially more aggressive, with a risk of bone destruction. Diagnosis must systematically be confirmed by biopsy, identifying soft-tissue parts, as telangiectatic sarcoma can mimic ABC. Intra-lesional sclerotherapy with alcohol is an effective treatment. In spinal ABC and in aggressive lesions with a risk of fracture, surgical treatment should be preferred, possibly after preoperative embolization. The risk of malignant transformation is very low, except in case of radiation therapy. PMID:25579825

    Simple bone cysts (SBCs) are benign bone tumors. However, the treatment of SBCs remains controversial because of their healing rate and the invasiveness of surgery. The purpose of the present study was to evaluate the treatment of SBCs using a cannulated hydroxyapatite (HA) pin.A total of 43 patients (35 males, 8 females; mean age 12.1 years; age range, 5-22 years) with SBCs were treated with continuous decompression by inserting ceramic HA pins between 1989 and 2014. The SBCs were located in the calcaneus in 23, the humerus in 15, the femur in 3, and the pelvis in 2 cases. In all patients, minimal fenestration of the cyst wall and curettage and multiple drilling in the cyst wall were performed, followed by insertion of the HA pin. The mean follow-up period was 26.6 months. Operating time, healing period, risk factors for recurrence, and the cure rate were evaluated.Healing was achieved without intervention in 38 patients after a mean of 6.4 months. Two patients had persistent small residual cysts, which had no changes after 1 year at the latest follow-up. There were 5 patients with recurrences (humerus 4, femur 1), who were cured by curettage and artificial bone grafting. The final healing rate by cannulation only using an HA pin was 88.2%. On Fisher exact test, age, site of SBCs, and distance from the physis were found to be significantly associated with SBC recurrence (P < 0.05).In the present study, cannulation using an HA pin for SBCs was found to be a useful technique, particularly for calcaneal cysts, because it is a minimally invasive procedure with a high cure rate. In patients <10 years, involvement of the humerus and contact with the growth plate were significant risk factors for SBC recurrence. PMID:26107670

    This paper describes an extremely rare case of a huge aneurysmal bone cyst (ABC) in the pelvis, occurring in the patient’s 5th decade of life. The patient presented with a history of painless huge pelvic mass for 10 years. Plain radiograph and computed tomography showed huge expansile lytic lesion arising from the right iliac bone. A biopsy was performed and histology confirmed diagnosis of aneurysmal bone cyst. Unfortunately, the patient succumbed to profuse bleeding from the tumour. PMID:22279501

    Aneurysmal bone cysts associated with tubular bones of the hand occur rarely and require particular diagnostic and therapeutic management techniques. While optimal treatment has not been established, accepted treatments range from aggressive radical treatment, including en bloc resection and excision diaphysectomy with strut bone grafting, to relatively simple techniques, such as thorough curettage followed by bone graft. Aggressive treatment approaches may be optimal for the cases with articular surface involvement, full-bone invasion of the phalanx or metacarpal, or more than 1 recurrence. We report a monocentric case of aneurysmal bone cysts involving metacarpal bone in a child who achieved favorable outcome with curettage and morselized cancellous bone grafts. PMID:25750953

    Aneurysmal bone cysts are rare skeletal tumors that most commonly occur in the first two decades of life. They primarily develop about the knee but may arise in any portion of the axial or appendicular skeleton. Pathogenesis of these tumors remains controversial and may be vascular, traumatic, or genetic. Radiographic features include a dilated, radiolucent lesion typically located within the metaphyseal portion of the bone, with fluid-fluid levels visible on MRI. Histologic features include blood-filled lakes interposed between fibrous stromata. Differential diagnosis includes conditions such as telangiectatic osteosarcoma and giant cell tumor. The mainstay of treatment is curettage and bone graft, with or without adjuvant treatment. Other management options include cryotherapy, sclerotherapy, radionuclide ablation, and en bloc resection. The recurrence rate is low after appropriate treatment; however, more than one procedure may be required to completely eradicate the lesion. PMID:22474093

  12. How simple are 'simple renal cysts'?

    2014-09-01

    The increasing use of medical imaging as an investigative tool is leading to the incidental and frequent finding of renal cysts in the general population. The presence of a solitary or multiple renal cysts has been generally considered benign in the absence of a family history of renal cystic disease or evidence of chronic kidney disease. Nonetheless, a number of recent studies have questioned this consensus by reported associations with the development of hypertension or malignant change. For these reasons, some clinicians consider the presence of renal cysts to be a contraindication to kidney donation. The situation is complicated by the different usage of the term 'simple' by some radiologists (to indicate non-complex lesions) or nephrologists (to indicate age-related non-hereditary lesions). We propose that the term 'simple' be replaced with the morphological description, Stage I renal cyst (Bosniak Classification). The presence of a Stage I renal cyst should not preclude kidney donation. However, occult renal disease should be excluded and appropriate donor assessment performed. PMID:25165175

    The traumatic bone cyst, an uncommon lesion of the jaws, belongs to the category of 'pseudocyst' owing to its lack of a lining epithelial membrane. It is an asymptomatic lesion, which is often diagnosed accidentally during routine radiological examination commonly present in the posterior mandible as a unilocular radiolucency with scalloping borders. The exact etiopathogenesis of the lesion is still debated, though the role of trauma is often associated. Here we report a rare case of traumatic bone cyst in the anterior mandible, in a 16-year-old female patient with a previous history of trauma to chin; diagnosed and treated successfully in our surgical unit. The case is discussed in relation to its clinical presentation, etiopathogenesis, diagnosis, management and prognosis. PMID:26028875

    An eighteen month old female Doberman pinscher dog was referred to teaching hospital of Adnan Menderes University, Faculty of Veterinary Medicine with the complaint of right forelimb lameness for a month. On the basis of clinical, radiographical, scintigraphical, computed tomographical and histopathological findings, aneurysmal bone cyst was diagnosed. Surgical curettage and bone cement treatment were applied. The patient recovered after 12 months. This case proves that aneurysmal bone cyst, without osteolysis and/or damages to the surrounding tissues, may result in a good prognosis if curettage and treatment with bone cement are done.

    Chondroblastoma is an uncommon benign bone tumour, involvement of epiphysis of long bones is typical. Chondroblastoma of the calcaneum is uncommon and its association with secondary aneurysmal bone cyst is even rarer. Only two cases of calcaneal chondroblastoma associated with secondary aneurysmal bone cyst have been reported till date. A 22-year-old male presented to the department of orthopaedics with complains of pain and swelling in the left heel since the last 10 months. On clinico-radiological grounds differentials considered were giant cell tumour of bone and aneurysmal bone cyst. In view of the histopathological findings of bone curettage and results of special stain and immunohistochemical marker, final diagnosis of chondroblastoma with secondary aneurysmal bone cyst, left calcaneum was rendered. Although rare, chondroblastoma should always be considered in osteolytic lesions of calcaneum. The identification of secondary aneurysmal bone cyst component is important as it has higher chances of recurrence than usual chondroblastoma. PMID:27504302

    Background Aneurysmal bone cysts are relatively uncommon in the facial skeleton. These usually affect the mandible but origin from the coronoid process is even rarer. To the best of our knowledge, this is the first reported case of a coronoid process aneurysmal bone cyst presenting as temporal fossa swelling. Case presentation A 17 year old boy presented with a progressively increasing swelling in the left temporal region developed over the previous 8 months. An expansile lytic cystic lesion originating from the coronoid process of the left mandible and extending into the infratemporal and temporal fossa regions was found on CT scan. It was removed by a superior approach to the infratemporal fossa. Conclusion Aneurysmal bone cyst of the coronoid process can attain enormous dimensions until the temporal region is also involved. A superior approach to the infratemporal fossa is a reasonable approach for such cases, providing wide exposure and access to all parts of the lesion and ensuring better control and complete excision.

    Renal cysts are generally classified as simple or complex and are further characterised under the Bosniak classification system. Most simple cysts are benign, asymptomatic and discovered incidentally. However, over time, these simple cysts can enlarge, become symptomatic and develop complications, requiring intervention. We present a case of a 70-year-old man with multiple comorbidities who presented with left lower quadrant abdominal pain and haematuria. An abdominal CT scan revealed a large, 26 cm exophytic cyst with high attenuation areas, septations and haemorrhage. Given the patient's tenuous condition and poor functional status, an interventional radiology-guided renal cyst aspiration was performed, resulting in successful reduction of size and symptom resolution. A follow-up ultrasound at 6 months showed no evidence of recurrence. Primary care providers should be aware of the prevalence of renal cysts and their complications, especially haemorrhage, particularly in high risk and elderly patients on anticoagulation or antiplatelet therapy.

    Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 2012. In the UBC group (352 cases) humerus, femur and calcaneus were found to be the most common sites, while acetabulum, scapula, scaphoid, lunatum, metacarpals, metatarsals, toe phalanges and ulna each accounted for less than 1%. In the ABC group (99 cases) the most common sites of involvement were femur, humerus and tibia, while finger phalanges, ilium, acetabulum, pubis, calcaneus, cuboid, and toe phalanges each accounted for only 1%. The differential diagnosis of cystic bone lesions should include both UBC and ABC. Pain complaints plead for the latter, except in case of fracture. PMID:26280957

    Summary Background: Aneurysmal bone cyst is an expansile bone lesion, non-neoplastic in nature, occurring most commonly in long bones. It is uncommon in facial bones and exceptionally rare in ethmoid bone. Ten cases of aneurysmal bone cysts of ethmoid bone have been reported so far. Case Report: A young adolescent presented with decreased vision and pain in the right eye. MRI revealed an expansile lesion having conspicuous fluid levels with a multiloculated appearance in the right ethmoid bone extending to the right orbit. CT was done to characterize better bone details. Both biopsy of the lesion and histopathology of resected specimen confirmed aneurysmal bone cyst. Conclusions: A characteristic appearance on MRI and CT examinations helped to confidently diagnose a relatively common lesion in an exceedingly rare location. PMID:22802795

    Aneurysmal bone cysts (ABCs) are benign bone tumors consisting of blood-filled cavities lined by connective tissue septa. Recently, the hypothesis that ABCs are lesions reactive to local hemodynamics has been challenged after the discovery of specific recurrent chromosomal abnormalities. Multiple cases of malignant transformation of ABC into (osteo)sarcoma have been described, as well as a number of cases of telangiectatic osteosarcoma which had been misdiagnosed as ABC. We herewith document a case of a pelvic ABC metastatic to the lung, liver, and kidneys. Diagnosis was confirmed by the presence of a break in the USP6 gene, which is pathognomonic for ABC, in a pulmonary metastasis of our patient. Sarcomatous transformation as an explanation for this behavior was ruled out by demonstrating diploid DNA content in both the pulmonary lesion and the primary tumor. PMID:19838726

    We designed a semiautomatic segmentation method to easily measure the volume of a bone cyst (simple or aneurysmal) from magnetic resonance imaging (MRI). This method only considers the fluid part of the cyst, even when there are several fluid intensities (fluid-fluid levels) or the cyst is multi-loculated. The nonhomogeneity phenomenon inherent in MRI was handled by a k-means clustering algorithm that classified all of the voxels corresponding to the cyst fluid as the same voxel intensity. Level-set segmentation was expanded into the whole cyst volume and the resulting segmented volume provided the measured cyst volume. The semiautomatic method was compared with the usual manual method (manual contour tracing) in terms of its ability to measure a known volume of water (gold standard) as well as the volume of 29 bone cysts. Both methods were equivalent with regards to the gold standard, but the semiautomatic method was more accurate. In terms of the experimental measurements, the semiautomatic method was more repeatable and reproducible, and less time-consuming and fastidious than the manual method. Our semiautomatic method uses only freeware and can be used routinely whenever measurement of a bone cyst volume is needed. PMID:19553051

    We report a case of multiple extraosseous aneurysmal cysts occurring in the muscle and subcutaneous plane of postero-lateral aspects of the upper right leg. They appeared about 15 months after resection of aneurysmal bone cyst of the upper end of the fibula. They varied in size from 2 cm to 5 cm. Radiologically they were well-defined lesions with central septate areas surrounded by a rim of calcification. Histologically they showed central cystic spaces separated by septa consisting of fibroblasts, osteoclast type of giant cells and reactive woven bone. Thus they showed histological similarity with aneurysmal bone cysts, but did not show any connection with the bone. Only very few examples of aneurysmal cysts of soft tissue had been described in the past one decade and they were reported in various locations including rare sites such as arterial wall and larynx. Recent cytogenetic analyses have shown abnormalities involving 17p11-13 and/or 16q22 in both osseous and extraosseous aneurysmal cysts indicating its probable neoplastic nature. Our case had unique features like multiplicity and occurrence after resection of primary aneurysmal bone cyst of the underlying bone. PMID:21139755

    An aneurysmal bone cyst is an uncommon benign primary bone tumor. Careful intralesional curettage through a wide cortical window in addition to cauterization with or without adjuvant therapy (phenol or hydrogen peroxide) and bone grafting or cementation is the preferred surgical treatment. Adjuvant or primary radiation of an aneurysmal bone cyst rarely is used because of its association with malignant transformation of the lesion. Several cases of late malignant transformation of primary aneurysmal bone cysts without adjuvant radiation have been reported. We provide additional documentation of two primary aneurysmal bone cysts treated surgically with careful intralesional curettage through a wide cortical window and allograft bone grafting without adjuvant radiation. At 5.5 years and 12 years after treatment, a telangiectatic osteosarcoma and a fibroblastic osteosarcoma, respectively, were identified in the site of the original lesions. Not only should aneurysmal bone cysts be evaluated carefully through histologic examination at presentation, patients also should be counseled regarding possible recurrence and the need for routine followups, especially if symptoms change.

    Aneurysmal bone cysts (ABCs) are benign, non-neoplastic, expansile, vascular, locally destructive lesions. The lesion may arise de novo (65%) or secondarily (35%) in pre-existing benign or malignant lesions (giant cell tumor, osteoblastoma, chondroblastoma, angioma, and others). The calcaneus is a rare localization for ABC, comprising only 1.6% of the cases. In this paper, we present a case of a female patient with a 3-month history of heel pain that got worse and was accompanied by swelling and difficulty in walking. The magnetic resonance images of the postero-lateral calcaneus showed a contrast-enhanced cystic lesion located in the medullary cavity; exophytic portion of the tumor extended into the soft tissue causing distinctive cortical thinning. Heterogeneous hyperintense septae formations and blood level components were also detected. After correlation with pathology results, the lesion was diagnosed as an ABC. Since an ABC of the calcaneus is a rarely seen phenomenon, we present the radiologic findings in this case and a review of the literature. PMID:25396076

    Aneurysmal bone cyst (ABC) is a vascular benign bony expansile lesion. The treatment is gross total resection. Surgery for a skull base aneurysmal bone cyst poses a significant challenge because of its vascularity and the adjacent neurovascular structures. We present the case of a young male with a temporal aneurysmal bone cyst who underwent gross total resection of the lesion. The external carotid artery (ECA) was temporarily clamped to cut off the vascular supply. There was no intraoperative event, and the patient made a good postoperative clinical recovery. This technique was used as an alternative to subselective endovascular embolization of the ECA branches. This case represents a simple yet cost-effective surgical technique to control bleeding for a highly vascular lesion such as ABCs, especially in resource-deficient countries. PMID:27334736

    A rare, large pediatric aneurysmal bone cyst with pathologic fracture of the distal tibia of a 4-year-old female was presented. Classic radiographic and magnetic resonance imaging findings have been discussed. In a comprehensive review of the literature, aneurysmal bone cysts are an infrequently reported neoplasm of the foot and ankle bones. Lesions are characteristically seen in patients younger than 20 years of age, but rarely younger than 5 years. The benign cyst has a 2:1 female-to male predilection. In long bones, the lesion is typically metaphyseal in nature. Although the pathogenesis is still unknown, there exists the possibility of two types of aneurysmal bone cysts: a primary type without preexisting lesion and a secondary form associated with some other lesion. The diagnosis of aneurysmal bone cyst can be strongly suspected by correlating the radiographic and magnetic resonance imaging findings. For definitive diagnosis, accurate histologic evaluation is imperative to rule out any confusion or possibility with a malignant tumor. PMID:9086721

    A unicameral bone cyst in the proximal humerus of a 3-year-old Norwegian forest cat was diagnosed by dynamic contrast-enhanced magnetic resonance imaging, surgical exploration, and histopathology. Surgical curettage and incorporation of bone cement led to full recovery. An osteosarcoma developed at the surgical site 17 months later. Thoracic radiographs showed pulmonary lesions consistent with metastasis. PMID:27041754

    We report a new case of aneurysmal bone cyst of the larynx occurring in a 22-year-old man. The lesion manifested with progressive breathing discomfort and appeared as a polypoid pedunculated mass attached to the subglottic mucosa. Microscopically, it featured numerous mononuclear and multinucleated giant cells surrounding cavernous spaces filled with blood. Foci of proliferating spindle cells and mature osteoid tissue could be recognized. There was no apparent relationship with the cricoid perichondrium. Clinical follow-up was negative for local recurrence. Based on this report and a review of the literature, we conclude that aneurysmal bone cyst of the larynx is phenotypically comparable to its bone homologue; however, its microscopic recognition may be difficult, especially on small biopsy fragments. Since it can be confused with several lesions, including telangiectatic osteosarcoma, awareness of this rare appearance of aneurysmal bone cyst is important to avoid unnecessary radical surgery.

    Soft tissue ganglion cysts are the most common benign tumours of the wrist; their pathogenesis remains controversial. We prospectively screened the radiographic appearance of the wrists of 51 patients presenting to a single surgeon with dorsal wrist ganglions during a one-year period. Postero-anterior and lateral radiographs were systematically performed looking for possible associated intraosseous ganglion cysts. There were 51 dorsal soft tissue ganglion cysts in 51 patients. We detected 29 associated intraosseous ganglia in 24 patients (47%): 16 ganglia in the lunate bone (55%), 5 in the capitate bone, 7 in the scaphoid and 1 in the trapezoid. Mean size of the intraosseous ganglia was 3 mm (range, 2 to 5 mm). This high prevalence of intraosseous ganglia in association with soft tissue ganglia has to our knowledge never been reported previously. A common aetiology for these two types of ganglion cysts may explain this high association rate. PMID:16305077

    Aneurysmal bone cysts are rare benign lesions of bone tissue, infrequent in craneofacial skeleton with regard to other structures like long bones or the spine. They are composed of sinusoidal and vascular spaces blood-filled and surrounded by fibrous tissue septa. We present a case of a 29-year-old Caucasian male with a big swelling in the left mandible associated to pain and rapid growth. He referred previous extraction of the left inferior third molar. On the X-ray study, an expansive multilocular and high vascularized bony lesion within the mandibular angle was observed. It produced expansion and destruction of lingual and buccal cortex. An incisional biopsy was performed showing a fibrous tissue with blood-filled spaces lesion suggestive of an aneurysmal bone cyst. After selective embolization of the tumour, surgical resection was done with curettage and immediate reconstruction of the defect with an anterior iliac crest graft. Aneurysmal bone cysts are non-neoplastic but locally aggressive tumours with occasional rapid growth that may be differentiated from other multilocular process like ameloblastoma, ossifying fibroma, epithelial cyst, giant cell granuloma and sarcomas. Treatment of choice consists on conservative surgical excision of the mass with curettage or enucleation. When resection creates a big defect, primary surgical reconstruction is recommended.

    Intraosseous ganglion cysts are rare causes of wrist pain. Surgical treatment of this pathologic condition yields good results and a low recurrence rate. The main complications are joint stiffness and vascular disturbances of the lunate bone. Wrist arthroscopy is a surgical technique that reduces the intra-articular operative area and therefore minimizes postoperative stiffness. This article describes an arthroscopic technique used for lunate intraosseous cyst resection associated with an autologous bone graft in a series of cases to prevent joint stiffness while respecting the scapholunate ligament. This study was based on a series of 4 patients, all of whom had wrist pain because of intraosseous ganglion cysts. Arthrosynovial cyst resection, ganglion curettage, and bone grafting were performed arthroscopically. Pain had totally disappeared within 2 months after the operation in 100% of patients. The average hand grip strength was estimated at 100% compared with the opposite side, and articular ranges of motion were the same on both sides in 100% of cases. No complications were reported after surgery. On the basis of these results, arthroscopic treatment of intraosseous synovial ganglion cysts seems to be more efficient and helpful in overcoming the limitations of classic open surgery in terms of complications.

    The objective of this study is to assess complete removal of the thyroglossal duct cyst (TGDC) and its tract(s) to the base of the tongue with sparing of the hyoid bone. This is a prospective cohort study. Tertiary hospital (Zagazig university hospital). This prospective study was carried out on 21 patients who had been diagnosed preoperatively as TGDC or fistula. All patients were managed by dissection and removal of the TGDC and its tract(s) to the base of the tongue with sparing of the hyoid bone. The study was conducted on 12 males (57.14 %) and 9 females (42.85 %) with mean age 6.8 years (4-20 years). After histopathological examination; 16 patients (9 male and 7 female) were proved to have TGDC and 5 patients (3 male and 2 female) were proved to have dermoid cyst. The hyoid bone could be preserved in all cases except in two cases for whom the middle third of the hyoid bone was removed with the specimen. Multiple tracts were found in three cases and could be identified and dissected successfully with sparing of the hyoid bone. Identification, dissection, and complete excision of the TGDC with its attaching tract(s) could be performed without hyoid bone resection with no recurrence and minimal minor complication. The impacts of this hyoid bone preservation versus removal on the pattern of swallowing and retroglossal space need to be studied. PMID:25859938

    Fetal ovarian cysts are the most frequent type of abdominal tumors in female fetuses with prenatal detection rate of more than 30%. The etiology of fetal ovarian cysts is unclear, but hormonal stimulation as well as presence of maternal diabetes, hypothyroidism, Rh iso-immune hemolytic disease and toxemia has been generally considered responsible for the disease. Complications of fetal ovarian cysts include compression of other viscera, cyst rupture, hemorrhage and, most frequently, ovarian torsion with consequent loss of the ovary. Management is controversial with several options described in the literature, including watchful expectancy, antenatal aspiration of simple cysts to prevent torsion and ovarian loss and finally, resection of all complex cysts in the neonatal period. To date, no case report has described recurrent complex cysts with rupture in the fetal period and recurrence of simple cyst in neonatal period. By presenting this case, we wanted to show that surgical intervention in case of prenatally diagnosed fetal ovarian cyst should be considered postnatally and only in symptomatic or complicated cases.

    2010-01-01

    Cyst walls of Entamoeba and Giardia protect them from environmental insults, stomach acids, and intestinal proteases. Each cyst wall contains a sugar homopolymer: chitin in Entamoeba and a unique N-acetylgalactosamine (GalNAc) homopolymer in Giardia. Entamoeba cyst wall proteins include Jacob lectins (carbohydrate-binding proteins) that cross-link chitin, chitinases that degrade chitin, and Jessie lectins that make walls impermeable. Giardia cyst wall proteins are also lectins that bind fibrils of the GalNAc homopolymer. While many of the details remain to be determined for the Giardia cyst wall, current data suggests a relatively simple fibril and lectin model for the Entamoeba cyst wall. PMID:20934911

    Objective Our goal was to document the presentation, location, diagnostic modalities, preoperative embolization status, treatment, histology, complications, and recurrence rates for aneurysmal bone cysts of the mobile spine. Methods We reviewed our institution's database to identify patients diagnosed with aneurysmal bone cysts of the mobile spine (excluding the sacrum) from 1995 through 2006. Of those 17 patients, three were treated elsewhere and 14 underwent surgical treatment at our institution. Of those 14 patients, the nine (mean age at presentation, 17.2 years; range, 5‥32 years) with at least 2 years of follow-up (average, 49.6 months; range, 24‥88 months) formed our study group. For those nine patients, we tabulated the presentation, location, diagnostic modalities, preoperative embolization status, treatment, histology, complications, and recurrence rates. Results Pain was the presenting symptom in all nine patients. The lesion most commonly occurred in the cervical spine (five); two occurred in the lumbar spine, and two occurred in the thoracic spine. Patients underwent resection and combined anterior and posterior spinal arthrodesis (six) or resection and posterior spinal arthrodesis (three). There were four complications: one iliac crest donor site infection, one incidental durotomy, and two neurologic defcits. We noted two recurrences (both within 3 months). Conclusions Aneurysmal bone cysts of the spine can be successfully treated with surgical resection and instrumentation. PMID:23576920

    Unicameral bone cysts (UBCs) are benign tumor-like lesions that commonly occur in the diaphyseal or metaphyseal region of the long bones within the first 2 decades of life. Until today, the pathogenesis of UBC has been unclear, but mechanisms such as vascular occlusion or a response to trauma have been supposed. During the past decade, in particular, the genetic aspects of the development of this rare lesion have been discussed. We present the first case of mirror image monozygotic twins with a mirror image UBC of the calcaneus. Our findings reinforce the importance of additional studies to understand the significance of cytogenetic factors in the etiology of UBC. PMID:25435010

    Symptomatic aneurysmal bone cysts with expansible lesions in the pelvis are rare in children. The management of an aggressive vascular lesion in a female child is challenging. The standard treatment for aneurysmal bone cysts is accompanied by a high risk of local recurrence. A 12-year-old female presented with a history of pelvic pain for 5 months. Plain radiographs and magnetic resonance imaging showed a very large expansile lytic lesion arising from the right iliac bone. Intralesional curettage, electric cauterization, chemical sclerotherapy and allogeneic bone graft were performed through the window of the iliac crest. At a follow-up consultation 3.5 years post-surgery, the child had painless full-range movement in the hip joint with no recurrence. Although many treatment options are described, our patient was treated successfully using curettage and allogeneic bone graft without recurrence.

ABC of the pubic ramus is a rare entity.. Case Report: We present a case of a 21 year old male who presented with a swelling of the right inguinal region which was gradually progressive. Radiologically, there was a lytic expansile lesion of the superior pubic ramus. A contrast computed tomography revealed multiloculated cystic cavities and histopathology confirmed the diagnosis of ABC. Surgical excision of the complete tumor by anterior approach was done. Till date (2 years since surgery) patient has no recurrence. Conclusion: ABC of pubic ramus is a rare entity and other differentials should always be kept in mind with confirmation of diagnosis by histopathology. Treatment with surgical curettage and bone grafting the defect is curative in selective cases but in this case due to size and location excision is the choice of treatment. PMID:27298931

    Objective. The aim of the study was to analyze the association between levels of adipokines in the breast cyst fluid and in the circulation in relation to the type of cysts. Material and Measurements. A cross-sectional study involved 86 women with breast cysts (42 with simple cysts and 44 with complex cysts). Plasma and breast cyst fluid leptin, adiponectin, visfatin/NAMPT, resistin, TNF-α, and IL-6 levels, in addition to serum levels of estradiol, progesterone and prolactin, and anthropometric parameters and body composition (by bioimpedance method), were measured. Results. The levels of leptin, adiponectin, and resistin were significantly lower in breast cyst fluid than in plasma regardless of the cyst type. Contrarily, the levels of visfatin/NAMPT and TNF-α were significantly increased, and IL-6 levels were similar in the breast cyst fluid and plasma in both study groups. There was no correlation between corresponding levels of leptin, adiponectin, resistin, visfatin/NAMPT, TNF-α, and IL-6 in breast cyst fluid and plasma. Conclusions. Higher levels of visfatin/NAMPT and TNF-α in the fluid from simple and complex breast cysts than in plasma suggest that their local production is related to inflammation. PMID:27293305

    Aneurysmal bone cysts are benign bone tumors that usually present in childhood and early adulthood. They usually manifest as expansile osteolytic lesions with a varying potential to be locally aggressive. Since their first description in 1942, a variety of treatment methods has been proposed. Traditionally, these tumors were treated with open surgery. Either intralesional surgical procedures or en bloc excisions have been described. Furthermore, a variety of chemical or physical adjuvants has been utilized in order to reduce the risk for local recurrence after excision. Currently, there is a shift to more minimally invasive procedures in order to avoid the complications of open surgical excision. Good results have been reported during percutaneous surgery, or the use of embolization. Recently, sclerotherapy has emerged as a promising treatment, showing effective consolidation of the lesions and functional results that appear to be superior to the ones of open surgery. Lastly, non-invasive treatment, such as pharmaceutical intervention with denosumab or bisphosphonates has been reported to be effective in the management of the disease. Radiotherapy has also been shown to confer good local control, either alone or in conjunction to other treatment modalities, but is associated with serious adverse effects. Here, we review the current literature on the methods of treatment of aneurysmal bone cysts. The indication for each type of treatment along reported outcome of the intervention, as well as potential complications are systematically presented. Our review aims to increase awareness of the different treatment modalities and facilitate decision-making regarding each individual patient. PMID:26793296

    The aneurysmal bone cyst (ABC) is a fast-growing tumor of undefined neoplastic nature. It is occasionally an aggressive benign lesion whose treatment of choice is a complete resection, even though the risk of profuse transoperative bleeding exists. We present a female patient with thoracic spine deformity, with progressive paresthesias and muscle weakness of lower extremities that evolved to paralysis of both lower extremities and sphincter incontinence. Based on radiographic films, lytic lesions were identified at T7 to T9 vertebrae as well as medullary space invasion. In electrophysiologic tests, a complete somatosensorial pathway block was reported. Prior to resection of the neoplastic lesion and thoracolumbar stabilization, an incisional biopsy was performed. There was no postoperative medullary functional improvement. Morphological findings corresponded to an aneurysmal bone cyst at T8. This lesion is mainly located in the long bones and less frequently of the spine, where instability and medullary compression may occur. It is possible to confuse this neoplasia with other lesions. Hence, definite diagnosis with biopsy is necessary for determining an adequate therapeutic plan to eradicate recurrence risk or associated neurologic sequelae, as well as to gain proper stability at the involved vertebral segments.

  18. Lower Limb Reconstruction with Tibia Allograft after Resection of Giant Aneurysmal Bone Cyst

    PubMed Central

    2016-01-01

    Aneurysmal bone cysts (ABCs) are benign, expansible, nonneoplastic lesions of the bone, characterized by channels of blood and spaces separated by fibrous septa, which occur in young patients and, occasionally, with aggressive behavior. Giant ABC is an uncommon pathological lesion and can be challenging because of the destructive effect of the cyst on the bones and the pressure on the nearby structures, especially on weight-bearing bones. In this scenario, en bloc resection is the mainstay treatment and often demands complex reconstructions. This paper reports a difficult case of an unusual giant aneurysmal bone cyst, which required extensive resection and a knee fusion like reconstruction with tibia allograft. PMID:27413565

    Although bone involvement associated with cyst hydatid is rarely seen, it can cause unintended results such as high recurrence rate, infection, sepsis, or amputation of relevant extremity. Because of this reason, its treatment is difficult and disputed. In the case of bifocal bone cyst hydatid in right femur, along with albendazole treatment, result of resecting cyst surgically and its treatment with teicoplanin with added bone cement is given. In conclusion, since the offered treatment method both supports bone in terms of mechanical aspect and also can prevent secondary infection, the method is thought to be a good and safe treatment approach.

    Aim. To evaluate the feasibility of percutaneous sclerotherapy of symptomatic simple abdominal cysts, using hypertonic saline and bleomycin, as an alternative to surgery. Materials and Methods. This study involved fourteen consecutive patients (ten women, four men, mean age: 59.2 y) with nineteen symptomatic simple cysts (liver n = 14, kidney n = 3, and adrenal n = 2) treated percutaneously using a modified method. Initially CT-guided drainage was performed; the next day the integrity of the cyst/exclusion of extravasation or communications was evaluated under fluoroscopy, followed by two injections/reabsorptions of the same quantity of hypertonic NaCl 15% solution and three-time repetition of the same procedure with the addition of bleomycin. The catheter was then removed; the patients were hospitalized for 12 hours and underwent follow-ups on 1st, 3rd, 6th, and 12th months. Cyst's volumes and the reduction rate (%) were calculated in each evaluation. Results. No pain or complications were noted. A significant cyst's volume reduction was documented over time (P < 0.001). On the 12th month 17 cysts disappeared and two displayed a 98.7% and 68.9% reduction, respectively. Conclusion. This percutaneous approach constitutes a very promising nonsurgical alternative for patients with symptomatic simple cyst, without complications under proper precautions, leading to eliminating the majority of cysts.

    A 110 x 70 x 60-mm hydatid cyst in the right kidney of a 5-year-old boy was treated using a laparoscopic approach. The renal hydatid cyst was not identified before the operation. There were no complications related to surgery and therapy. The child was under follow-up for 12 months and there was no evidence of recurrence on ultrasonography and computed tomography during this period. To our knowledge, this is the first case of renal hydatid cyst treated by laparoscopic approach in a child. PMID:19013417

    ABSTRACT A 4-year-old Shih-Tzu, referred for an enlarged left carpus, was diagnosed with a unicameral bone cyst. A customized titanium device was inserted into cystic lesion and fixed by titanium screws. Sufficient strength of the affected bone with the device inserted to maintain limb function was established after resection of contents of cystic lesion. There was no deterioration of the lesion of bone cyst, and acceptable function of the affected limb with no clinical signs of lameness was maintained during 36 months follow-up. The results of this study demonstrated that bone cyst curettage and use of a customized titanium device could provide an effective alternative treatment of huge lesion of unicameral bone cysts with the intent of preventing pathologic fractures.

    The authors report 6 cases of cyst formation in an infarcted segment of the humerus, tibia, or femur, a rare occurrence. Histopathological confirmation was obtained in each case. Three lesions involved the humerus, suggesting that this is a high-risk site. A cyst should be suspected when an expanding radiolucent, sharply demarcated lesion arises in a necrotic segment of bone. The cortex is thinned but remains intact. Characteristics which distinguish a cyst from sarcoma are discussed.

    The increased use of Ultrasonography (US) has led to increased detection of simple hepatic cysts. For symptomatic cysts treatment is necessary. Until some years ago surgery was the only therapy. We have treated a large number of patients with Percutaneous Alcohol Sclerotherapy (PAS) and evaluated retrospectively the efficacy of this approach. Data on 21 patients with symptomatic simple hepatic cysts were reviewed retrospectively. Cysts had a mean diameter of 9 cm (range: 7–15 cm). PAS was always performed under local anesthesia and US guidance. 25% of the volume was replaced with 95% ethanol and then completely aspirated after 20–30 minutes. No complications or deaths occurred. In all patients symptoms disappeared after treatment. In 15 out of 21 cases there was no evidence of residual cyst on US, computed tomography (CT) or magnetic resonance (MRI). In 6 patients with shorter follow-up, cysts showed a mean reduction in diameter of 50%. The mean follow-up was 18 months (range 6–60 months). We conclude that PAS is easy with low risk for the patients and with good long-term results; it should therefore become the procedure of choice for simple hepatic cysts. PMID:7880778

  6. Arthroscopic Bone Grafting of Deep Acetabular Cysts Using a Curved Delivery Device

    Acetabular intraosseous cysts are frequently encountered in patients with dysplasia or femoroacetabular impingement. Small cysts are typically addressed by removing the cyst lining and stimulating healing via microfracture or abrasion chondroplasty. In contrast, larger cysts involving 1-3 cm3 frequently require additional fortification with bone graft material to facilitate osseous ingrowth and cyst healing. Previous arthroscopic reports have described the use of rim trimming to access the extra-articular side of the cyst, with subsequent use of straight metal cannulas for delivery of bone graft material. The downsides of this technique include the requirement for rim trimming, which may be ill advised in patients with normal coverage or dysplasia, as well as the creation of a second breach in the cyst wall, precluding pressurization of the bone graft material. We describe an arthroscopic technique using a curved delivery device allowing for deeper penetration into the cyst cavity through the articular side and greater delivery of bone graft material.

    Juvenile bone cysts usually are asymptomatic and may manifest as pathological fractures. Since the new method of flexible intramedullary nailing (" Elastic Stable Intramedullary Nailing" - ESIN or " Embrochage Centro- Médullaire Elastique Stable" - ECMES) has demonstrated superb results in the treatment of non-pathologic fractures of the long bones in childhood, this method is rapidly gaining popularity for the treatment of spontaneous or pathological fractures. Given the self-limiting natural history of juvenile bone cysts with eventual spontaneous healing, our goal is to stabilise the pathological fracture and the biomechanically weakened humerus. We treated 15 patients with 16 pathological fractures (one re-fracture) due to juvenile bone cysts of the proximal humerus. All fractures healed completely without pseudarthrosis. Complications were a secondary fracture in otherwise correctly positioned nails. Five of the 15 implants remain in situ, in 6 cases a repeat osteosynthesis was necessary, in one case the nails had to be changed because of the re-fracture. Ten of the 15 juvenile bone cysts healed over a period of 3 years, the nails were removed and so far there have been no further fractures in this group. In the other 5 cases, the juvenile bone cysts have progressively filled with sclerotic bone, and the nails remain in situ. PMID:12664415

  9. Pathologic fracture of the distal radius in a 25-year-old patient with a large unicameral bone cyst

    PubMed Central

    2014-01-01

    Background Distal radius fractures (DRF) are often referred to as osteoporosis indicator fractures as their incidence increases from age 45. In the group of young adults, distal radius fractures normally result from high-energy trauma. Wrist fractures in young patients without adequate trauma thus raise suspicion of a pathologic fracture. In this report we present the case of a fractured unicameral bone cyst (UBC) at the distal radius in a young adult. To the author’s best knowledge, this is the first detailed report in an UBC at the distal radius causing a pathologic DRF in an adult patient. Case presentation A 25-year-old otherwise healthy male presented to our Emergency Department after a simple fall on his right outstretched hand. Extended diagnostics revealed a pathologic, dorsally displaced, intra-articular distal radius fracture secondary to a unicameral bone cyst occupying almost the whole metaphysis of the distal radius. To stabilize the fracture, a combined dorsal and volar approach was used for open reduction and internal fixation. A tissue specimen for histopathological examination was gathered and the lesion was filled with an autologous bone graft harvested from the ipsilateral femur using a reamer-irrigator-aspirator (RIA) system. Following one revision surgery due to an intra-articular step-off, the patient recovered without further complications. Conclusions Pathologic fractures in young patients caused by unicameral bone cysts require extended diagnostics and adequate treatment. A single step surgical treatment is reasonable if fracture and bone cyst are treated appropriately. Arthroscopically assisted fracture repair may be considered in intra-articular fractures or whenever co-pathologies of the carpus are suspected. PMID:24925068

    PURPOSE We aimed to evaluate the effectiveness of single-session ultrasound-guided percutaneous ethanol sclerotherapy in simple breast cysts. METHODS From January 2002 to January 2014, 35 simple breast cysts (mean volume, 8.2 mL; range, 4–33 mL) in 28 females (mean age, 39 years) were evaluated. In a single session, all cysts were aspirated using 20G needles, refilled with 99% ethanol (90% of the volume of the aspirated fluid), and reaspirated completely after 10 minutes of exposure under ultrasound guidance. Follow-up ultrasonography examinations were performed at one week, one month, three months, and six months for all patients and 12 months, 18 months, and 24 months for available patients. Follow-up duration varied between 6 and 24 months (mean, 15 months). RESULTS The technical success rate of ultrasound-guided percutaneous ethanol sclerotherapy was 97%. The needle tip was dislocated and ethanol was given into the breast parenchyma in one patient (3%). One cyst (3%) was reaspirated at the first week follow-up due to intracystic hemorrhage. Of the 34 cysts treated, 25 (74%) completely responded to therapy and were no longer detectable on follow-up examinations. Eight cysts (24%) significantly decreased in size and then completely disappeared at six months. At the end of the follow-up period, the clinical success rate reached 100%, and none of the cysts were visible. Except mild to moderate sensation of burning or pain which disappeared or subsided significantly in a couple of minutes, no other complications were observed in patients. CONCLUSION Ultrasound-guided ethanol sclerotherapy is a fast, safe, and highly effective method in the treatment of simple breast cysts. PMID:27087190

    Aneurysmal bone cysts (ABCs) are benign bone lesions with annual incidences ranging from 1.4 to 3.2 cases per million people. Approximately, 10-30% of ABCs are found in the spine. Such lesions are traditionally treated with curettage or other intralesional techniques. Because ABCs can be locally aggressive, intralesional resection can be incomplete and result in recurrence. This has led to increased use of novel techniques, including selective arterial embolization (SAE). This study aims to: (1) compare outcomes based on extent of surgical resection, and (2) compare the efficacy of SAE versus surgical resection. Clinical data pertaining to 71 cases of spinal ABCs were ambispectively collected from nine institutions in Europe, North America, and Australia. Twenty-two spinal ABCs were treated with surgery, 32 received preoperative embolization and surgery, and 17 were treated with SAE. Most tumors were classified as Enneking stage 2 (n = 29, 41%) and stage 3 (n = 29, 41%). Local recurrence and survival were investigated and a significant difference was not observed between treatment groups. However, all three local recurrences occurred following surgical resection. Surgical resection was further categorized based on Enneking appropriateness. Recurrences only occurred following intralesional Enneking inappropriate (EI) resections (P = 0.10), a classification that characterized 47% of all surgical resections. Furthermore, 56% of intralesional resections were EI, compared to only 10% of en bloc resections (P = 0.01). Although SAE treatment did not result in any local recurrences, 35% involved more than five embolization procedures. Spinal ABCs can be effectively treated with intralesional resection, en bloc resection, or SAE. Preoperative embolization should be considered before intralesional resection to limit intraoperative bleeding. Treatment plans must be guided by lesion characteristics and clinical presentation.

    The treatment of cystic lesions and the extraction of impacted third molars are 2 of the most common procedures in oral and maxillofacial surgery. The surgical treatment of cysts of the jaws can consist of a cystectomy, a cystotomy, or a staged combination of the 2 procedures. The surgical techniques developed for the extraction of impacted third molars are: coronectomy, orthodontic extraction, and surgery using intraoral or extraoral methods. There are various complications related to both surgical treatments. With regards to these complications, authors' department has developed a new surgical technique based on a previously described technique, which provides better support to the mucoperiosteal flap and improves bone regeneration after healing. Additionally, authors' goal was to reduce the risk of nerve injury, which has been achieved thanks to a direct visualization of the inferior alveolar nerve as well as cystic lesion or the dental element. The surgical procedure described produces major advantages over the traditional alternatives, despite needing a longer operation. This technique is particularly useful in the treatment of cystic lesions that have caused considerable bone loss. It can also be utilized for cysts or impacted dental elements strictly linked to the inferior alveolar nerve. PMID:27171951

    An 11-year-old girl had a lytic, benign-appearing, expansive lesion of the distal tibia radiologically interpreted as an aneurysmal bone cyst (ABC). Tissue from two extensive curettage procedures was also histologically diagnosed as ABC. Approximately 50 months after the onset of symptoms, and 28 months after her last curettage, a highly pleomorphic osteosarcoma developed. The patient had not received prior radiation therapy. The cases in the literature of possible malignant transformation of ABC are reviewed. The authors separate their case from telangiectatic osteosarcoma, and from "aneurysmal bone cyst-like osteosarcoma." PMID:1913522

    We describe the spontaneous rupture of a simple hepatic cyst. A 62-year-old woman was admitted for right upper quadrant pain of sudden onset. The patient denied a history of abdominal trauma. Computed tomography of the abdomen showed a 13-cm-diameter solitary hepatic cyst in the right lobe. Part of the cyst surface was irregular, and the internal echo was heterogeneous. Retained fluid was detected under the liver capsule. Ten days after admission, computed tomography revealed that the volume of fluid retained under the liver capsule had decreased but that the hepatic cyst had enlarged again. The patient was referred to our hospital for further evaluation and treatment. Physical examination revealed mild right upper quadrant pain, but no signs or symptoms of peritonitis or abnormalities of the chest or heart. Percutaneous puncture was performed with a needle and an 8-French pigtail catheter under ultrasonographic guidance. Brown serous fluid was aspirated. After the removal of approximately 1,000 mL of fluid, contrast medium was injected to check for communications between the cyst and the biliary tree and to document the absence of leakage into the peritoneal cavity. After complete aspiration of the cyst fluid, 200 mg of minocycline hydrochloride dissolved in 10 mL of saline was injected into the cyst, and the catheter was flushed with 10 mL of saline (total volume of saline, 20 mL). The catheter was then clamped for 30 minutes. After percutaneous aspiration, the patient's symptoms resolved. Minocycline hydrochloride was injected daily for 7 days, and the catheter was removed. There has been no evidence of recurrence after 2 years. PMID:25959204

    Purpose Although angiogenesis has been implicated in the promotion of renal cyst growth in autosomal dominant polycystic kidney disease, no studies have investigated the role of angiogenesis in the growth of simple renal cysts. The aim of current study was to investigate the effect of chemotherapy with the antivascular endothelial growth factor antibody bevacizumab on renal cyst development and growth in cancer patients. Materials and Methods We retrospectively reviewed the medical records of 136 patients with a variety of cancers that were treated with bevacizumab-based chemotherapy for metastatic disease. The presence of and changes in renal cysts were evaluated by retrospective analysis of computed tomography scans performed for assessment of tumor response to bevacizumab-based therapy. Results The median age of the patients was 64 years. Renal cysts were identified in 66 patients, in whom 33 (50%) had a single cyst and the rest had 2 or more cysts. The average dose of bevacizumab was 2.68 mg/kg per week. Median duration of treatment was 33 weeks. Average cyst size was 1.9±2.4 cm at the beginning of the study and the majority of the cysts (54 patients, 84%) did not change in size or shape during bevacizumab treatment. No patients were identified with new cysts. Cyst size changed in 10 patients (16%): an increase of 15% to 40% from the baseline size in 5 patients and a decrease in size of 10% to 70% in another 5 patients. The duration of bevacizumab therapy was significantly longer in the subgroup of patients with diminished or increased cyst size than in the patients with stable cyst size: 62 weeks versus 29 weeks, respectively (p=0.0002). Conclusions Our data demonstrated that simple renal cysts were stable in size and number in the vast majority of cancer patients treated with bevacizumab. PMID:26682018

    The aneurysmal bone cyst is a pseudotumoral lesion that can take several aspects. This is a rare lesion representing 1% of bone tumors. It appears usually during the first 30 years of life. The pathogenesis is that of a process of “dysplasia/hyperplasia”, favored by a circulatory deficiency and hemorrhage within the lesion and the phenomena of osteoclasis. The objective of this work is to illustrate with analysis, the specific forms and atypical aneurysmal bone cyst which often pose a diagnostic challenge requiring radiological investigation with histological confirmation. We report eight pediatric cases of aneurysmal cysts collected over a period of 3 years, 3 boys and 5 girls. All patients had standard radiographs. MRI was performed in three patients. The diagnosis was confirmed histologically. The atypia has been in the seat: fibula (1 case), metaphyseal (2 cases), diaphyseal (4 cases) and metatarsal (1 case). Aneurysmal bone cyst is a rare benign tumor with predilection to the metaphysis of long bones. Atypical forms even fewer are dominated by the atypical seat. PMID:24244797

    Osteochondrosis arises as a result of focal failure of the blood supply to growth cartilage. The current aim was to examine the pathogenesis of pseudocysts and true cysts in subchondral bone following failure of the blood supply to the articular-epiphyseal cartilage complex in horses. Cases were recruited based on identification of lesions (n = 17) that were considered likely to progress to or to represent pseudocysts or true cysts in epiphyseal bone in histological sections and included 10 horses ranging in age from 48 days to 5 years old. Cases comprised 3 warmbloods, 3 Standardbreds, 1 Quarter horse and 1 Arabian with spontaneous lesions and 2 Fjord ponies with experimentally induced lesions. Seven lesions consisted of areas of ischemic chondronecrosis and were compatible with pseudocysts. Two lesions were located at intermediate depth in epiphyseal growth cartilage, 2 lesions were located in the ossification front, 2 lesions were located in epiphyseal bone and 1 lesion was located in the metaphyseal growth plate (physis). Ten lesions contained dilated blood vessels and were compatible with true cysts. In 2 lesions the dilated blood vessels were located within the lumina of failed cartilage canals. In the 8 remaining lesions areas of ischemic chondronecrosis were associated with granulation tissue in the subjacent bone and dilated vessels were located within this granulation tissue. Failure of the blood supply and ischemic chondronecrosis can lead to formation of pseudocysts or dilatation of blood vessels and formation of true cysts in the epiphyseal bone of horses.

    The calcaneus is the most common tarsal affected by unicameral bone cysts (UBCs); however, the treatment of calcaneal UBCs remains controversial. The purpose of the present systematic review was to evaluate the treatment modalities for calcaneal UBCs. A systematic review was performed using clinical studies of calcaneal UBCs with a minimum of 1 year of follow-up and level I to IV evidence. Ten studies with 171 patients (181 cysts) were selected. Heel pain and radiographic cyst consolidation were the primary outcomes. A series of Z tests were used to compare the outcomes in the nonoperative and operative groups, cannulated screw and bone augmentation groups, and autografting and allografting groups. All patients treated with open curettage and bone augmentation had significant improvements in heel pain (p < .001). Only 1.1% ± 1.0% of the cysts treated conservatively had healed on radiographs compared with 93.0% ± 13.0% of the cysts after surgery (p < .001). A greater percentage of patients treated with bone augmentation had preoperative heel pain and resolution of that pain than did patients treated with cannulated screws (p < .001). Autografting had a significantly greater percentage of radiographic cyst consolidation than did allografting (97.4% ± 11.1% versus 85.1% ± 15.8%, p < .001, Z = 3.5). Objective outcomes data on calcaneal UBCs are relatively sparse. The results of the present review suggest that open curettage with autograft bone augmentation is the most effective procedure. We would encourage future comparative clinical studies to elucidate differences in UBC treatment modalities. PMID:25638776

    Management of unicameral bone cysts (UBC) remain controversial. These cysts seldom heal spontaneously or even after pathological fracture. Sometimes these cysts can be very large and incredibly troublesome to the patient. Various treatments exist with variable success rates. We present our experience of treating these lesions by continuous drainage. Over a seven year period, six patients with unicameral bone cysts were treated by inserting a modified drain into the wall of the cyst. The aim of surgery was to place the drain in a dependent area of the cyst, through the cortex allowing for continuous drainage. This was achieved through a small incision under radiographic control. A cement restrictor (usually used for femoral canal plugging during total hip replacements) was modified and inserted to prevent closure of the drain site. A redivac drain was passed through the plug into the cyst. The drain was left in place for a week to establish an epithelialized pathway which hopefully would remain patent, into the subcutaneous tissues, after the drain had been removed. There were four males and two females in the group and the age range was 6 -12 years. Four of the lesions were in the upper humerus, one in the proximal femur and the other one in the proximal tibia. Healing was rated according to the modified Neer classification. Grade 1 (healed) and Grade 2 (healed with defect) was defined as excellent outcome. Persistent /Recurrent cysts (Grade 3 and 4) were noted as unsatisfactory. Five cases were completely healed. Only one had a further fracture and there were no recurrent fractures. All the patients reported complete comfort and they all were able to re-engage in recreational activities without restriction. We think that reducing the intra-medullary pressure in these lesions will lead to healing. We report a safe and minimally invasive technique for the management of UBC. PMID:26587064

    OBJECTIVES--To examine the contents of intraosseous cysts in patients with rheumatoid arthritis (RA) through the signal intensity characteristics on gadolinium-DTPA (Gd-DTPA) enhanced magnetic resonance imaging. METHODS--The hand or foot joints of nine patients with the cystic form of RA (where the initial radiological abnormality consisted of intraosseous cysts without erosions) were imaged before and after intravenous administration of Gd-DTPA. A 0.6 unit, T1 weighted spin echo and T2* weighted gradient echo were used to obtain images in at least two perpendicular planes. RESULTS--Most cysts showed a low signal intensity on the non-enhanced T1 weighted (spin echo) images and a high signal intensity on the T2* weighted (gradient echo) images, consistent with a fluid content. No cyst showed an enhancement of signal intensity on the T1 weighted images after intravenous administration of Gd-DTPA, whereas synovium hyperplasia at the site of bony erosions did show an increased signal intensity after Gd-DTPA. Magnetic resonance imaging detected more cysts (as small as 2 mm) than plain films, and the cysts were located truly intraosseously. In six patients no other joint abnormalities were identified by magnetic resonance imaging; the three other patients also showed, after Gd-DTPA administration, an enhanced synovium at the site of bony erosions. CONCLUSIONS--It is suggested that intraosseous bone cysts in patients with RA do not contain hyperaemic synovial proliferation. The bone cysts in patients with the cystic form of RA may be the only joint abnormality. Images PMID:8257207

    Baker's cysts are located in the posteromedial region of the knee between the medial belly of the gastrocnemius muscle and semimembranosus tendon. In adults, these cysts are related to intra-articular lesions, which may consist of meniscal lesions or arthrosis. In children, these cysts are usually found on physical examination or imaging studies, and they generally do not have any clinical relevance. Ultrasound examination is appropriate for identifying and measuring the popliteal cyst. The main treatment approach should focus on the joint lesions, and in most cases there is no need to address the cyst directly. Although almost all knee cysts are benign (Baker's cysts and parameniscal cysts), presence of some signs makes it necessary to suspect malignancy: symptoms disproportionate to the size of the cyst, absence of joint damage (e.g. meniscal tears) that might explain the existence of the cyst, unusual cyst topography, bone erosion, cyst size greater than 5 cm and tissue invasion (joint capsule).

    The efficacy of osteochondral allografts (OCA) may be affected by osseous support of the articular cartilage, and thus affected by bone healing and remodeling in the OCA and surrounding host. Bone cysts, and their communication pathways, may be present in various locations after OCA insertion and reflect distinct pathogenic mechanisms. Previously, we analyzed the effect of OCA storage (FRESH, 4°C/14d, 4°C/28d, FROZEN) on cartilage quality in fifteen adult goats after 12 months in vivo. The objectives of this study were to further analyze OCA and contralateral non-operated (Non-Op) CONTROLS from the medial femoral condyle to (1) determine the effect of OCA storage on local subchondral (ScB) and trabecular (TB) bone structure, (2) characterize the location and structure of bone cysts and channels, and (3) assess the relationship between cartilage and bone properties. (1) Overall bone structure after OCA was altered compared to Non-Op, with OCA samples displaying bone cysts, ScB channels, and ScB roughening. ScB BV/TV in FROZEN OCA was lower than Non-Op and other OCA. TB BV/TV in FRESH, 4°C/14d, and 4°C/28d OCA did not vary compared to Non-Op, but BS/TV was lower. (2) OCA contained “basal” cysts, localized to deeper regions, some “subchondral” cysts, localized near the bone-cartilage interface, and some ScB channels. TB surrounding basal cysts exhibited higher BV/TV than Non-Op. (3) Basal cysts occurred (a) in isolation, (b) with subchondral cysts and ScB channels, (c) with ScB channels, or (d) with subchondral cysts, ScB channels, and ScB erosion. Deterioration of cartilage gross morphology was strongly associated with abnormal μCT bone structure. Evidence of cartilage-bone communication following OCA repair may favor fluid intrusion as a mechanism for subchondral cyst formation, while bone resorption at the graft-host interface without affecting overall bone and cartilage structure may favor bony contusion mechanism for basal cyst formation.

    2014-01-01

    Background Unicameral bone cyst (UBC) is the most common benign lytic bone lesion seen in children. The aim of this study is to investigate clinical factors affecting pathological fracture and healing of UBC. Methods We retrospectively reviewed 155 UBC patients who consulted Nagoya musculoskeletal oncology group hospitals in Japan. Sixty of the 155 patients had pathological fracture at presentation. Of 141 patients with follow-up periods exceeding 6 months, 77 were followed conservatively and 64 treated by surgery. Results The fracture risk was significantly higher in the humerus than other bones. In multivariate analysis, ballooning of bone, cyst in long bone, male sex, thin cortical thickness and multilocular cyst were significant adverse prognostic factors for pathological fractures at presentation. The healing rates were 30% and 83% with observation and surgery, respectively. Multivariate analysis revealed that fracture at presentation and history of biopsy were good prognostic factors for healing of UBC in patients under observation. Conclusion The present results suggest that mechanical disruption of UBC such as fracture and biopsy promotes healing, and thus watchful waiting is indicated in these patients, whereas patients with poor prognostic factors for fractures should be considered for surgery.

Hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. CT scan and MRI showed a skull base mass that was confirmed as ABC in histopathology. The case was unusual and interesting due to the clinical presentation of jugular foramen syndrome and radiological findings such as severe enhancement and multiosseous involvement. PMID:23329983

    A 20-year-old female patient presented with two masses located in the left liver. In this patient, a computed tomography (CT) scan revealed a hypodense mass and a second well-defined mass with a calcified nodule in the left hepatic lobe. No enhancements were apparent in or around the masses. A laparotomy was performed due to the patient’s symptoms, namely, the atypical CT findings and a risk of rupture of the subcapsular lesion. The operation revealed two masses in the left hepatic lobe and a left liver resection was subsequently performed. One of the masses involved segment III and the other mass was located in segment IV. The histopathologic findings supported a diagnosis of collagenous nodule mixed simple cyst and hemangioma. A diagnosis of collagenous nodule mixed simple hepatic cyst is extremely rare and radiologically mimics a teratoma, hepatolithiasis, parasitic cyst, or hemangioma. Although hepatic hemangiomas are the most common benign tumors found in the liver, the present case showed atypical radiographic features. PMID:25892897

    A 74-year-old noncirrhotic woman presented with abdominal distension and pain in the right hypochondrium. Contrast-enhanced computed tomography (CT) demonstrated multiple large simple liver cysts occupying the right lobe of the liver, the largest of which was 19 cm in diameter. Gastric varices were enhanced in the fundus of the stomach. The patient underwent surgery to deroof the hepatic cysts with ablation using argon beam coagulation. Esophagogastroduodenoscopy (EGD) showed that the portal hypertensive gastropathy was ameliorated after the operation; however, the fundal varices were only slightly decreased. After the operation, we observed that the hepatic vein waveform gradually changed from a gently curved pattern to a normal triphasic pattern. We treated the fundal varices with balloon-occluded retrograde transvenous obliteration 3 months after the initial operation. We describe our successful treatment of this rare case and discuss the utility of hepatic vein waveform analysis in the study of portal hypertension. PMID:24620641

  12. A comparison of cyst wall curettage and en bloc excision in the treatment of aneurysmal bone cysts

    PubMed Central

    2013-01-01

    Background The recurrence rate after aneurysmal bone cyst (ABC) treatment is quite high despite its benign nature. In ABC therapy, curettage is the treatment of choice; en bloc excision results in a lower recurrence rate, but more extensive reconstructive surgery is needed with associated morbidity. The aim of the present study was to compare the outcomes of the two treatment options. Methods A retrospective analysis was performed on 26 patients treated for ABCs: 16 by curettage and 10 by en bloc excision. Each lesion was classified according to Enneking and patients were followed up for a mean time of 9.2 years. On follow-up, radiological examination and functional assessment (range of motion, muscle strength) were performed. Recurrence was defined as the presence of an osteolytic lesion, especially one with a tendency to grow. Results On follow-up, the following symptoms were more prevalent in the en bloc excision group compared to the curettage group: pain (en bloc 20% versus curettage 6.25%), limb length differences (en bloc 20% versus curettage 12.5%), reduced range of motion (en bloc 20% versus curettage 6.25%) and muscle strength impairment (en bloc 50% versus curettage 31.2%); however, the differences were not statistically significant (P >0.05). In the curettage group, two cases of postoperative complications and two cases of recurrence were seen, while in the en bloc excision group one case of complications was noted. Conclusions Curettage is a standard procedure in ABC management. En bloc excision is another option, albeit more technically demanding, that may be considered in recurrent lesions with extensive bone destruction or for cysts in an expendable location.

    Introduction: Intraosseous ganglions, although share same pathology as the soft tissue ganglions are rare entities, further rare in carpals. Cases of intraosseous ganglions are reported in literature mostly in lower limbs and lunate among carpals, with treatment options ranging from curettage and grafting to calcium phosphate cement injection and finally to arthroscopic treatment. Case report: Here, we present a case of 2 years follow up of 40 years old female with nonspecific clinical finding of wrist and slight limitation of restriction of motion, diagnosed as intraosseous ganglion cyst of scaphoid. This case was treated with curettage and bone grafting having excellent results with visual and analog pain scores reduced from 68 to 11 and range of motion was 90° extension to 80° flexion and full grip strength. Conclusion: Intraosseous ganglion cyst should be considered in differential diagnosis of chronic dull wrist pain because they produce disabling symptoms which ceases once adequately treated by curettage and bone grafting.

    The purpose of the present study was to evaluate the advantages and disadvantages of an endoscopic procedure for patients with symptomatic calcaneal bone cyst compared with an open procedure. The cases of 16 consecutive patients with a calcaneal bone cyst were reviewed. Of the 16 patients, 8 had undergone the open procedure (O group) from October 2003 to August 2011, and 8 had undergone the endoscopic procedure (E group) from September 2011 to April 2013. The endoscopic procedure used a 2-portal technique in which skin incisions were made to avoid the peroneal tendon according to the preoperative ultrasonography. All surgeries (open or endoscopic) consisted of curettage of the inner wall of the bone cyst, followed by injection of calcium phosphate cement. The following factors were evaluated: radiographic assessment, operative time, postoperative adverse effects, and interval to the return to sports. No significant difference between the 2 groups was observed in the operative time (53.5 ± 6.5 minutes in the O group and 56.1 ± 13.8 minutes in the E group). The E group experienced no adverse effects; however, the O group had 1 temporary irritation in the sural nerve area and 1 calcium phosphate cement leakage along the peroneal tendon sheath. The interval to a return to sports was significantly shorter in the E group (14.5 ± 0.9 weeks in the O group and 6.5 ± 1.1 weeks in the E group; p < .01). In conclusion, endoscopic surgery is a useful approach for the treatment of calcaneal bone cysts, allowing early rehabilitation and an early return to sports without any adverse effects.

    Soft tissue aneurysmal bone cyst is a rare entity, with about 20 cases reported in literature, only 3 of which are in patients over 40 years of age. We present a case of a 41 year old Latin American female who presented for evaluation of atraumatic chest pain with radiation to the left shoulder. Her initial workup was negative, including radiographic imaging of the chest and left shoulder. 4 months later, she presented to her orthopedic surgeon with a palpable mass and mild left shoulder pain. Radiographs acquired at that time demonstrated a 7.0 × 5.5 × 6.7 cm mass with rim calcification in the region of the upper triceps muscle. Subsequent CT imaging showed central areas of hypodensity and thin septations, a few of which were calcified. MR evaluation showed hemorrhagic cystic spaces with multiple fluid-fluid levels and enhancing septations. Surgical biopsy was performed and pathology was preliminarily interpreted as cystic myositis ossificans, however on final review the diagnosis of soft tissue aneurysmal bone cyst was made. The lesion was then surgically excised and no evidence of recurrence was seen on a 3 year post-op radiograph. Following description of our case, we conduct a literature review of the imaging characteristics, diagnosis, and treatment of soft tissue aneurysmal bone cyst. PMID:25926918

    Giant cell tumor is colonized by aneurismal bone cyst in only 15% of cases and cervical localisation accounts for less than 1% of giant cell tumors. We are reporting a rare case of a C2 hypervascularized giant cell tumor colonized by an aneurismal bone cyst treated with an effective preoperative Onyx embolization followed by a full tumor resection. The patient experienced a moderate cervical spine injury 2 months prior admission followed by a progressive stiff neck and cervicalgia. CT and MRI identified a lytic lesion of the body and lateral masses of the C2 with encasement of both vertebral arteries. The angiography showed a hypervascularization of the lesion from the vertebral and external carotid arteries as well as a thrombosis of the V3 segment of the right vertebral artery at the C1 level. A posterior occipito-C3/C4 fixation and a tumor biopsy were performed. Histopathological examination concluded to a giant cell tumor colonized by an aneurismal bone cyst. Three weeks later, the patient developed a right upper extremity deficit. The MRI showed an increased C1-C2 stenosis and an increase of the hypervascularization. Three sessions of embolization by the onyx were performed. During surgery a near total tumor devascularisation was observed and a complete resection of the tumor was achieved through an anterolateral approach. Reconstruction consisted of a cementoplasty of the C2 body and odontoïd process with an anterior C3-prosthesis plate. The postoperative course was uneventful. PMID:22695034

    Aneurysmal bone cyst of the foot is extremely rare and the involvement of medial cuneiform has never been reported in the literature. In this report, we describe a 15-year-old boy who presented with a 6-month history of pain and swelling in his left foot. Radiograph demonstrated a lytic lesion in the medial cuneiform extending on to the middle cuneiform, the navicular bone and the base of the first metatarsal. En bloc resection of the lesion was performed using a dorsal longitudinal incision along the first ray. Tricortical iliac crest graft was harvested and shaped to fill the defect. Two drill holes were made and the tibialis anterior tendon was attached to the graft. Prepared, morcellised allograft was placed along the junction of autograft and host bone. At 1-year follow-up, the patient was pain free, the medial arch of the foot was maintained and the graft had united with the host bone. PMID:24563041

    Aneurysmal bone cyst (ABC) is a benign expansile bone tumor, most commonly involving the medulla of long bones. ABC rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary ABC changes, and telangiectatic osteosarcoma. Both of these are sometimes mistaken microscopically for primary ABC. We review the characteristics of ABC cases in our center and report four unusualsurface ABCs arising in the subperiosteal or cortical region of long bones, identified among 38 histologically proven ABCs during a four-year period in our center. The surface ABCs occurred at an older agewith a predilection for diaphysis of femur, tibia, and humerus. PMID:27200397

    Dental implant procedures, both surgical placement and preimplant bone augmentation, have become an integral aspect of the oral and maxillofacial surgeon's practice. The number of dental implants placed each year continues to increase as a result of increasing patient exposure and awareness of dental implants, the increased functional and esthetic dental demands of general practitioners and patients, the overall increase in age of the US patient population, and expanded insurance coverage of dental implant-related procedures. This article outlines relevant surgical procedures aimed toward reconstructing alveolar ridge defects to restore intra-arch alveolar discrepancies before restoration-driven dental implant placement.

    Objective The purpose of this report is to describe a case of an aneurysmal bone cyst presenting as a pathologic fracture in a young athlete. Case report A 12-year-old patient presented to a chiropractic teaching clinic with a 1-week history of posterior neck pain and stiffness following a helmet-to-helmet collision in football practice. Cervical spine radiographs were taken. Lateral view radiograph demonstrated a pathologic fracture through a lytic, expansive lesion in the posterior arch of C7 with mild subluxation of the C7/T1 apophyseal joints and angulation of the C7/T1 disk space. Based upon these findings, additional diagnostic imaging was ordered. Findings on advanced imaging studies included the following: On computed tomography, the C7 lesion showed medullary destruction, cortical thinning and expansion, and a horizontally oriented fracture through the spinous and lamina. Magnetic resonance imaging studies for sagittal T2 and contrast-enhanced T1-weighted magnetic resonance images revealed fluid/fluid levels in the C7 spinous and peripheral enhancement with contrast. Outcome The patient was referred to a local hospital for treatment. The lesion was treated with resection of the posterior arch, and an aneurysmal bone cyst was confirmed histologically. The patient developed a kyphotic deformity at the site of resection and cervical instability. A subsequent fusion was performed. Conclusion Aneurysmal bone cysts are rare lesions. In this case, the initial traumatic history masked the underlying pathology. Although rare, pathologic fracture should be considered in cases of vertebral fracture in young patients. PMID:24711787

    In a series of 105 cases of aneurysmal bone cyst, 18 showed an unusually high level of mitotic activity and/or increased nuclear pleomorphism which complicated the differential diagnosis with respect to telangiectatic osteosarcoma. An attempt was made to use semi-automatized morphometric and histophotometric techniques to establish objective morphological differences between these unusual cases of aneurysmal bone cyst and 16 cases of telangiectatic osteosarcoma. Three cases (two of aneurysmal bone cyst and one of telangiectatic osteosarcoma) proved unsuitable for analysis. In 24 of the remaining 31 cases (77%) a computerized discriminant analysis permitted correct discreimination with a high degree of certainty on the basis of quantitative nuclear characteristics determined in paraffin sections. In the other 7 cases the diagnosis was less certain (3), doubtful (2) or erroneous (2). The relevant nuclear characteristics were (in ascending sequence of discrimination): the largest nuclear surface area, the mitotic index, and the percentage of nuclear sections exceeding an arbitrarily chosen limit of 60 micron2. The criterion of nuclear size for discrimination between these benign and malignant lesions could be applied for two reasons: firstly, because a group of extremely large nuclei occur in malignant cases, and secondly, because the average nuclear size is larger in malignant than in benign lesions. The extremely large nuclei occur as only a small percentage of the total nuclear population. The other variables investigated, i.e., cellularity and nuclear contour ratio, did not contribute greatly to the differentiation. In 11 cases, the average nuclear Feulgen extinction was estimated as an additional variable. PMID:140511

    Purpose This study evaluated the healing in cystic defect of the jaw to substantiate our understanding of spontaneous bone healing after enucleation of jaw cysts subjectively and with analysis of digital postoperative panoramic radiographs. Materials and Methods Fourty four consecutive patients reporting to the Department of Dental and Oral Surgery, during the period between 2008-2012 having maxillary and mandibular cysts treated by either surgical enucleation or by marsupialization followed by enucleation were evaluated for subsequent bone formation at the site of cystectomy defect by subjective clinical examination along with digital radiographic examination. Postoperative clinical and radiographic examinations were performed at 6,9,12, and 24 months. Bone regeneration was evaluated by reduction of the size of residual cavities at the cystectomy defect using digital orthopantomogram. Results Out of 44 patients 15 patients completed two years of follow-up with all the patients having 6 months follow-up. The maximum size of the cystic pathology was 150.40mm and minimum of 14.73mm at the time of presentation (average size of 58.16mm). Twenty patients were diagnosed with odontogenic keratocyst, with one patient having multiple OKC associated with Gorlin Goltz Syndrome, 17 patients had dentigerous cyst, 5 had Radicular cyst; solitary bone cyst and globulomaxillary cyst formed one each. Uneventful healing and spontaneous filling of the residual cavities were obtained in all cases. The digital analysis of the postoperative radiographs showed mean values of reduction in size of the residual cavity of 25.85% after 6 months, 57.13% after 9 months, 81.03% after one year and 100% after two year. Conclusion Spontaneous bone regeneration can occur after surgical removal of jaw cysts without the aid of any graft materials even in large cystic cavity sufficiently surrounded by enough bony walls. This simplifies the surgical procedure, decreases the overall cost of surgery, and

    Traumatic bone cysts can mimic the signs and symptoms of an endodontic lesion. This case reports on a 19-year-old male patient who was referred for endodontic assessment of a symptomatic tooth with a gingival swelling and a draining sinus at the furcation of a mandibular second molar. Radiographically, a periradicular radiolucency is evident. A prior history of trauma as well as removal of the wisdom teeth was determined. After careful diagnosis unnecessary endodontic intervention was avoided. Surgical exploration, curettage and the generation of a blood clot resulted in healing at the 6 month review appointment. The tooth remained responsive to pulp sensibility testing at that time. PMID:21771187

In an attempt to identify sonographic features that could help distinguish these two types of cysts, we retrospectively analyzed 64 cases of fluid-filled hepatic cysts whose parasitic nature was ultimately excluded. This experience allowed us to develop a simple scoring system that quantifies the likelihood that hepatic cysts are non-parasitic. Sonographic criteria, together with the results of standard serological testing for cystic echinococcosis, proved to be sufficiently specific to allow definitive diagnosis without resorting to further tests.

    Bone morphogenetic protein use in spinal surgery for off-label indications continues to remain popular. One area where its use has known associated radicular complications is posterior or transforaminal lumbar interbody fusion. These complications include radiculitis, cyst development, and heterotopic ossification, amongst others. Typically, cyst development has been treated surgically. We present two cases of bone morphogenetic protein-related cysts treated medically and thus, present medical treatment as an alternative treatment option. PMID:27014519

    Aneurysmal bone cyst (ABC) is a benign, expansile lesion typically affecting the long bones and vertebrae of patients younger than 20 years. Approximately 2% of ABCs occur in the head and neck region, most commonly affecting the mandible. Although the most common co-existing lesion associated with ABCs is the giant cell tumor, ABCs can be radiologically confused with telangiectatic osteosarcoma in cases of aggressive behavior and rapid growth. Here, we report a case of an aggressive ABC of the maxilla confused with telangiectatic osteosarcoma in a patient who underwent several operations for an osteoblastoma that was diagnosed histopathologically. This case highlights the need for a differential diagnosis both radiologically and histopathologically, because ABCs can easily be interpreted as a giant cell tumor or an osteoblastoma, and, on occasion, can be mistaken for osteogenic malignancies.

    An aneurysmal bone cyst (ABC) is a type of reactive reparative bone neoplasm that rarely occurs in the head and neck. To date, only a small number of cases have been previously reported. The present study reports the case of a 58-year-old male who presented with a tumor in the laryngeal cricoid cartilage, a rare position for a tumor, who subsequently underwent treatment by surgical resection. Based on the observations of the present study and a literature review, it was concluded that an ABC of the larynx can be identified based on a combination of radiology and postoperative histopathology examinations. However, following a tracheotomy and excision, the difficulty of performing tracheal cannula removal is inevitable. The present study described in detail a rare disease, ABC, occurring in the larynx. More cases are required for follow-up studies. PMID:26622349

    Background The different treatment strategies for bone cysts in children are often associated with persistence and high recurrence rates of the lesions. The safety and clinical outcomes of a combined mechanical and biological treatment with elastic intramedullary nailing, artificial bone substitute and autologous platelet rich plasma are evaluated. Methods From 02/07 to 01/09 we offered all children with bone cysts the treatment combination of elastic intramedullary nailing (ESIN), artificial bone substitute (Orthoss®) and autologous platelet rich plasma, concentrated by the Gravitational Platelet Separation (GPS®) - System. All patients were reviewed radiologically for one year following the removal of the intramedullary nailing, which was possible because of cyst obliteration. Results A cohort of 12 children (4 girls, 8 boys) was recruited. The mean patient age was 11.4 years (range 7-15 years). The bone defects (ten humeral, two femoral) included eight juvenile and four aneurysmal bone cysts. Five patients suffered from persistent cysts following earlier unsuccessful treatment of humeral bone cyst after pathologic fracture; the other seven presented with acute pathologic fractures. No peri- or postoperative complications occurred. The radiographic findings showed a total resolution of the cysts in ten cases (Capanna Grade 1); in two cases a small residual cyst remained (Capanna Grade 2). The intramedullary nails were removed six to twelve months (mean 7.7) after the operation; in one case, a fourteen year old boy (Capanna Grade 2), required a further application of GPS® and Orthoss® to reach a total resolution of the cyst. At follow-up (20-41 months, mean 31.8 months) all patients showed very good functional results and had returned to sporting activity. No refracture occurred, no further procedure was necessary. Conclusions The combination of elastic intramedullary nailing, artificial bone substitute and autologous platelet rich plasma (GPS®) enhances the

    The patella is an unusual location for primary and metastatic bone tumors to develop. The most frequently encountered primary osteolytic lesions at the patella include giant cell tumors of the bone (GCT), chondroblastoma and aneurysmal bone cysts (ABC). However, the presentation of an ABC originating secondary to a GCT at the patella is rare. The present study describes such a case in a 46-year-old female. The differential diagnosis of the condition was extensive. The patient underwent curettage and the addition of bone cement to fill the defect. Pathological analysis of the resected tissue demonstrated that the lesion was consistent with an ABC forming secondary to a GCT. A 3-month follow-up was completed subsequent to the surgery, with a computed tomography scan demonstrating no evidence of recurrence. However, frequent and continuous observations of the patient following diagnosis are planned in order to evaluate the long-term efficacy of the surgical treatment. To the best of our knowledge, the present study describes the third reported case in the literature of this rare, double synchronous, benign tumor located at the patella. PMID:26893764

    We report the case of a 10-year-old girl with a soft tissue aneurysmal bone cyst (STABC) located in the posterior aspect of the left shoulder. Conventional radiography revealed an oblong mass with a calcified rim. On the computed tomography scan, the lesion appeared to have a non-uniform intralesional density with an incomplete rim. Magnetic resonance imaging revealed a multi-cavity lesion with fluid-fluid levels. Following pathological examination, the lesion was diagnosed as a STABC. This may be only the twentieth reported case in the English literature of this extremely rare benign tumor occurring in soft tissue. Eight months after surgery the patient was assessed at our outpatient clinic and found to have excellent mobility of her left shoulder and no sign of recurrence. PMID:22740948

    Painful subungual tumor masses in the toes usually emerge as glomus tumors or subungual exostoses. We present a patient with an aneurysmal bone cyst located subungually in whom the diagnosis was delayed due to inadequate diagnostic procedures, which led to marked destruction of the distal phalanx of the great toe of the right foot. After biopsy, the distal phalanx could not be preserved due to critical soft tissue involvement and the size of the process. Thus, we describe this rare entity to encourage clinicians to establish the diagnosis by biopsy of a tissue swelling of unclear origin and duration that does not resolve after a short time. Imaging examinations are useful in demonstrating periosteal involvement and extension of the lesion and can be helpful in the diagnostic algorithm. An interdisciplinary approach is a top priority to ensure optimal treatment. PMID:27106295

    Aneurysmal bone cysts (ABCs) involving condyle are unusual clinical presentation affecting younger group of society with only 12 cases reported till today in English literature. In this case of ABC condyle following resection, reconstruction of temporomandibular joint was done by alloplastic condylar prosthesis as a primary choice. Monthly basis follow-up was done for 1-year with a successful result. Reviewing the reconstructive options used in ABC condyle cases we found that the condylar head add-on system has shown a satisfactory result in comparison to costochondral graft with no donor site morbidity. We recommend condylar head add-on system should be preferred as a primary reconstructive option, reserving the autograft for recurrence cases. PMID:26668469

    The authors describe the case of a 6.6-cm symptomatic spinal aneurysmal bone cyst (ABC) in a 17-year-old athlete treated percutaneously. Surgical treatment was not considered as the first option owing to its invasiveness and associated morbidity. CT-guided cryoablation of the expansile part of the ABC was performed for tumour shrinkage and nerve decompression. Thermal insulation, temperature monitoring and functional control/electrostimulation of the neural structures at risk were applied. Finally, the bony defect was cemented. No complications occurred during the procedure. Complete resolution of the ABC on imaging and clinical improvement were achieved. Percutaneous cryoablation should be considered as an alternative treatment option, especially when tumour size reduction is desired. PMID:25091121

    The aneurysmal bone cyst (ABC) is a benign cystic and expanding osteolytic lesion consisting of bone-filled spaces of variable size, separated by connective tissue containing trabeculae of bone or osteoid tissue and osteoclast giant cells. Radiographic findings may vary from unicystic or moth-eaten radiolucencies to extensive multilocular lesions with bilateral expansion and destruction of mandibular cortices. Treatment modalities include curettage (with reported recurrences) and resection with immediate reconstruction. The main arterial and feeder vessels may be embolized to prevent profuse intraoperative blood loss and achieve a bloodless surgical field. Failed embolization may necessitate ligation of the external carotid artery of the affected side. PMID:23450035

    Aneurysmal bone cyst (ABC) is an uncommon, non-neoplastic, expansive and erosive bone lesion. Considered as a pseudocyst due the lack of epithelial lining, the presence of giant cells and similarity to other lesions can make preoperative diagnosis difficult; biopsy findings must be co-related to complete clinical and radiological assessment. ABC's controversial etiopathogenesis and variable clinicopathological presentations have been widely described, but to date, there are just a few reports in literature describing the development of fibrous dysplasia (FD) from an ABC, and even less cases occurring in the jaws. We describe the case of an ABC in an 8 year-old male patient, affecting the body of the mandible, which showed accelerated growth associated to thinning of the buccal, lingual and lower cortical plates. The treatment consisted of repetitive surgical resection, curettage of the lesion and mandibular reinforcement with osteosynthesis reconstruction plates. A 16-month follow-up showed self-limitation of the overgrowth. The final histopathological and radiological analysis confirmed the FD diagnosis. PMID:27408470

    We present the clinical, radiographic, and pathologic features of a telangiectatic osteosarcoma (TOS) of the right femoral neck in a 20-year-old man which was initially diagnosed and managed as an aneurysmal bone cyst (ABC). The lesion recurred twice. At the second recurrence TOS was diagnosed. The first local recurrence was recognized 4 years 8 months after the first operation. The clinical diagnosis for the recurrent lesion was recurrent ABC, and curettage and bone graft with internal fixation were performed. The second local recurrence was observed 8 months after the second surgery. The right lesser trochanter appeared destroyed on the radiograph, and a large medial soft tissue mass was demonstrated by computed tomography. The patient underwent wide resection of the tumor with prosthetic replacement of the right proximal femur. The histologic section for this lesion showed a blood-filled cystic lesion, and its wall contained sarcomatous cells with atypical mitoses and tumor osteoid. The histologic diagnosis for the second recurrent lesion was high-grade TOS. The retrospective review of the histologic section for the primary lesion showed similar features to ABC except for a few bizarre cells without mitosis in the tissue of cystic wall. The patient demonstrates no evidence of disease 13 months after the last surgery without adjuvant therapy (he declined chemotherapy). PMID:15570421

    The substance of the patella is an uncommon location for tumor occurrence and development. The present study reports a case of giant cell tumor (GCT) of the patella, combined with an aneurysmal bone cyst (ABC). To the best of our knowledge, this is the second report of GCT with ABC published in English. GCT is the most common type of benign tumor. Secondary ABC is frequently associated with GCT, but this symbiotic tumor rarely occurs in the patella. A 27-year-old male patient was examined at the outpatient clinic, and clinicopathological characteristics of the tumor were observed. X-ray and computed tomography (CT) scans revealed a lytic lesion located in the center of the right patella. Curettage, followed by autogenic and allograft bone grafting, was performed. Histopathologically, the lesion was diagnosed as a GCT with secondary ABC. No recurrence or metastasis was identified during the 1-year follow-up period. The present study reports a case of GCT with secondary ABC, and discusses the rare location and histopathological type of this tumor, in order to improve diagnosis and treatment of patellar tumors in general.

    An unmet need remains for a bone graft substitute material that is biocompatible, biodegradable and capable of promoting osteogenesis safely in vivo. The aim of this study was to investigate the use of a novel collagen-hydroxyapatite (CHA) bone graft substitute in the clinical treatment of a mandibular bone cyst in a young horse and to assess its potential to enhance repair of the affected bone. A 2 year-old thoroughbred filly, presenting with a multilobulated aneurysmal bone cyst, was treated using the CHA scaffold. Post-operative clinical follow-up was carried out at 2 weeks and 3, 6 and 14 months. Cortical thickening in the affected area was observed from computed tomography (CT) examination as early as 3 months post-surgery. At 14 months, reduced enlargement of the operated mandible was observed, with no fluid-filled area. The expansile cavity was occupied by moderately dense mineralized tissue and fat and the compact bone was remodelled, with a clearer definition between cortex and medulla observed. This report demonstrates the promotion of enhanced bone repair following application of the CHA scaffold material in this craniomaxillofacial indication, and thus the potential of this material for translation to human applications.

    We present a case of spinal tumor, with fibrohistiocytoma combined with aneurysmal bone cyst (ABC) at the pedicle and transverse process of T7 in a 63-year-old female. ABC is a rare skeletal tumor and spinal ABC is extremely rare. Fibrohistiocytoma is a type of primary benign bone tumor. ABC is also a rare bone tumor that most often occurs in the pelvis. The combined lesion of two primary bone benign tumors is relatively rare in clinic. In addition, fibrohistiocytoma and ABC are widely confused with other giant cell containing tumors of the bone. X-rays, magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) scans were performed and assessed. Finally, the diagnosis was confirmed by pathological tests. The patient underwent surgery and had an extremely good recovery. The correct diagnosis of a spine tumor is important when determining the surgical procedure. PMID:24223633

    Arginine vasopressin (AVP) has a key role in osmoregulation by facilitating water transport in the collecting duct. Recent evidence suggests that AVP may have additional effects on renal function and favor cyst growth in polycystic kidney disease. Whether AVP also affects kidney structure in the general population is unknown. We analyzed the association of copeptin, an established surrogate for AVP, with parameters of renal function and morphology in a multicentric population-based cohort. Participants from families of European ancestry were randomly selected in three Swiss cities. We used linear multilevel regression analysis to explore the association of copeptin with renal function parameters as well as kidney length and the presence of simple renal cysts assessed by ultrasound examination. Copeptin levels were log-transformed. The 529 women and 481 men had median copeptin levels of 3.0 and 5.2 pmol/L, respectively (P<0.001). In multivariable analyses, the copeptin level was associated inversely with eGFR (β=-2.1; 95% confidence interval [95% CI], -3.3 to -0.8; P=0.002) and kidney length (β=-1.2; 95% CI, -1.9 to -0.4; P=0.003) but positively with 24-hour urinary albumin excretion (β=0.11; 95% CI, 0.01 to 0.20; P=0.03) and urine osmolality (β=0.08; 95% CI, 0.05 to 0.10; P<0.001). A positive association was found between the copeptin level and the presence of renal cysts (odds ratio, 1.6; 95% CI, 1.1 to 2.4; P=0.02). These results suggest that AVP has a pleiotropic role in renal function and may favor the development of simple renal cysts. PMID:25270071

    Introduction: We report an osteoarthritic patient with huge sub-chondral cyst-like lesions in the Anterior part of distal femur. Deep and large bone defects and severe lateral laxity due to Advanced osteoarthritis was successfully treated with semi-constrained type total knee arthroplasty with long stem. Case Report: A 70yrs old Female was admitted in our institution diagnosed with severe bilateral Osteoarthritis. The x-rays showed bone on bone Tricompartment OA Knee with Varus Malalignment. She was posted for Single Stage Bilateral Total Knee Replacement and as planned the Left Knee Was Operated first. After exposure, Proximal Tibial, Distal Femoral Cuts and measurement of extension gaps the synovium from the anterior Femur was removed and sizing was done. The AP cut was then proceeded with. We spotted a small Osteochondral Cyst in the Anterior Femur which was curretted to remove the cystic material, which is when we realised that the cyst was large and communicating with the medulary canal. The remaining Femoral preparations was done keeping in mind the risk of iatrogenic fracture and extension Stem was used in the femur. The defect was then packed cancellous bone graft. Conclusion: If suspected a Preoperative MRI should be done to exclude any sub-chondral cysts osteochondral defects and any surprise during surgery. Usually one should keep extension stems ready for difficult cases. Operating surgeon should know his implants very well, as in many standard implants extension stems can only be used when distal femur cuts are taken accordingly as 5° Valgus. Mini incision should be avoided because it may fail to reveal such surprises and may land into periprosthetic fractures. PMID:27298967

We did an en bloc excision of locally aggressive tumor through anterior plus posterior approach and stabilization by lateral mass screw fixation and anterior cervical instrumentation. Involvement of several adjacent cervical vertebrae by an aneurysmal bone cyst is rare, and conventional treatment with curettage and bone grafting is most likely to carry a high rate of recurrence and spinal instability. We recommend complete excision of the tumor and instrumentation in a single stage to avoid instability. PMID:26288549

In this manuscript, we hereby describe two cases of ABC spine treated by curettage, vertebral cement augmentation for control of bleeding and internal stabilization with two years followup. To the best of our knowledge, this is the first case report in the literature describing the role of cement augmentation in spinal ABC in controlling vascular bleeding in curettage of ABC of spine. Case 1: A 22 year old male patient presented with chronic back pain. On radiological investigation, there were multiple, osteolytic septite lesions at L3 vertebral body without neural compression or instability. Percutaneous transpedicular biopsy of L3 from involved pedicle was done. This was followed by cement augmentation through the uninvolved pedicle. Next, transpedicular complete curettage was done through involved pedicle. Case 2: A 15-year-old female presented with nonradiating back pain and progressive myelopathy. On radiological investigation, there was an osteolytic lesion at D9. At surgery, decompression, pedicle screw-rod fixation and posterolateral fusion from D7 to D11 was done. At D9 level, through normal pedicle cement augmentation was added to provide anterior column support and to control the expected bleeding following curettage. Transpedicular complete curettage was done through the involved pedicle with controlled bleeding at the surgical field.

    Aneurysmal bone cyst is a benign, cystic lesion of bone composed of blood-filled spaces separated by fibrous septa. Relatively few cases of aneurysmal bone cyst have been cytogenetically characterized, yet abnormalities of the short arm of chromosome 17 appear to be recurrent. In this study, conventional cytogenetic analysis of 43 aneurysmal bone cyst specimens from 38 patients over a 12-year period revealed clonal chromosomal abnormalities in 12 specimens. Karyotypic anomalies of 17p, including a complex translocation and inversion, were identified in eight of these 12 specimens. In an effort to further define the aberrant 17p breakpoint, fluorescence in situ hybridization (FISH) analyses were performed using a series of probe combinations spanning a 5.1 Mb region between the TP53 (17p13.1) and Miller-Dieker lissencephaly syndrome (17p13.3) gene loci. These studies revealed the critical breakpoint locus at 17p13.2, flanked proximally by an RP11-46I8, RP11-333E1, and RP11-457I18 bacterial artificial chromosome (BAC) probe cocktail and distally by an RP11-198F11 and RP11-115H24 BAC and RP5-1050D4 P1 artificial chromosome (PAC) probe cocktail. Overall, abnormalities of the 17p13.2 locus were identified by metaphase and/or interphase cell FISH analysis in 22 of 35 (63%) aneurysmal bone cyst specimens examined including 26 karyotypically normal specimens. These cytogenetic and molecular cytogenetic findings expand our knowledge of chromosomal alterations in aneurysmal bone cyst, further localize the critically involved 17p breakpoint, and provide an alternative approach (ie FISH) for detecting 17p abnormalities in nondividing cells of aneurysmal bone cysts. The latter could potentially be utilized as an adjunct in diagnostically challenging cases. PMID:15044915

Treatment with the combined monophasic oral contraceptives reduces functional ovarian cysts. Yaz (drospirenone/ethinyl estradiol) is a low-dose combined oral contraceptive pill containing 20 μg ethinyl estradiol and 3 mg drospirenone. In addition to contraceptive effects, Yaz has anti-mineralocorticoid and anti-adrenergic effects. Ovocept- low-dose LD is also a low-dose combined oral contraceptive drug containing 30 μg ethinyl estradiol and 3 mg norgestrol. Ovocept-LD has some side-effects such as weight gain, spotting, breast tenderness, nausea, and headache. Materials and Methods: Being a clinical study, the present research was carried out on 42 patients with the simple ovarian cysts from 2010 to 2012. 84 Patients were assigned to A and B groups. Group A received Yaz once a day for a period of 28 days and group B received Ovocept-LD once a day for a period of 21 days. After treating by Yaz and Ovocept-LD, Cysts were evaluated by ultrasound. Results were analyzed by the SPSS software. A P < 0.05 was considered the significance threshold. Results: Obtained results indicated that both Yaz and Ovocept-LD had an effect on the simple ovarian cysts. Statistical tests, however, has shown that the effect of Yaz has been significantly more than that of Ovocept-LD. Conclusion: Given the faster and better recovery effect, and the lesser side effects of Yaz as compared to Ovocept-LD, it is recommended to use Yaz for the simple ovarian cysts. PMID:25337535

  13. Juxta-articular bone cysts (intra-osseous ganglia): a clinicopathological study of eighty-eight cases.

    PubMed

    Schajowicz, F; Clavel Sainz, M; Slullitel, J A

    1979-02-01

    The clinical, radiographic and pathological features of eighty-eight cases of histologically verified intra-osseous ganglia in eighty-three patients are described. All were located in the subchondral bone adjacent to a joint and most frequently involved the hip, the ankle (medial malleolus), the knee and the carpal bones. Forty-seven of the eighty-three patients were male and all the patients were between fourteen and seventy-three years of age, with an average age of forty-one years. There are two fundamental types of intra-osseous ganglia, one apparently arising by penetration of juxta-osseous ganglion into the underlying bone, a mechanism proved in fourteen of our eighty-eight cases (16 per cent); in the remaining seventy-four cases, the ganglion cyst was primarily intra-osseous ("idiopathic"). The initial cause of the intramedullary mucoid degeneration is discussed. We believe that mechanical stress and repeated minor trauma near the surface of the bone may lead to intramedullary vascular disturbance with consequent foci of aseptic bone necrosis. The revitalisation of these areas causes fibroblastic proliferation, followed by mucoid degeneration of the connective tissue, possibly due to some unknown local factor. Curettage or excision is usually effective, and recurrence (only four cases) is exceptional. PMID:422629

    Background: Typical aneurysmal bone cysts (ABCs) are osteolytic, multicystic lesions with parietal sclerosis and blood-filled cysts. In rare instances, the cystic components may be completely absent. Such solid variants in ABC (s-ABC) exhibit a solid architecture; making the clinical, radiological, and histological differentiation from other solid bone tumors like osteosarcoma (especially giant cell rich osteosarcoma) and giant cell tumor, a difficult task. Case Report: We report the case of a 45–year-old male presenting with a giant solid cervical spine lesion. Histopathology revealed solid variant of ABC, even though the radiological and fine needle aspiration cytology studies pointed toward a giant cell tumor. Conclusion: We aim to discuss the clinical, radiological, and histological findings of solid ABC (a rare benign entity) vis-à-vis the common neoplastic entities of osteosarcoma and giant cell tumor. The histopathological nuisances in making the diagnosis of s-ABC are put forth, along with its impact on management of such giant bony spinal lesions. PMID:26005581

    The soybean cyst nematode (SCN) is a major cause of soybean yield reduction. The objective of this study was to evaluate the efficiency of marker-assisted selection to identify genotypes resistant to SCN race 3 infection, using Sat_168 and Sat-141 resistance quantitative trait loci. The experiment was carried out under greenhouse conditions, using soybean populations originated from crosses between susceptible and resistant parent stock: CD-201 (susceptible) and Foster IAC (resistant), Conquista (susceptible) and S83-30 (resistant), La-Suprema (susceptible) and S57-11 (resistant), and Parecis (susceptible) and S65-50 (resistant). Plants were inoculated with SCN and evaluated according to the female index (FI), those with FI < 10% were classified as resistant to nematode infection. Plants were genotyped for SCN resistance using microsatellite markers Sat-141 and Sat_168. Marker selection efficiency was analyzed by a contingency table, taking into account genotypic versus phenotypic evaluations for each line. These markers were shown to be useful tool for selection of SCN race 3. PMID:26985946

    Unicameral bone cysts can predispose patients to pathologic fracture and deformities of growth. Treatment options vary from continuous decompression with transcortical placement of a cannulated screw to percutaneous aspiration and injection of medical-grade calcium sulfate. From 2005 to 2007, we treated 22 patients with unicameral bone cysts using aspiration and injection of calcium sulfate. Three patients experienced acute laryngospasm and one patient developed tachyarrhythmia, temporarily, associated with injection of calcium sulfate. All reactions occurred in patients under age 18 without predisposing risk factors and resolved spontaneously with supportive care. Although the mechanism is unclear, we hypothesize that these reactions are either due to the nociceptive stimulus of the calcium sulfate injection or a systemic calcium bolus. Clinicians using this product for this indication should be aware that such reactions may occur. We suggest endotracheal intubation and communication to the anesthesiologist about the time of the injection in preparation for these idiopathic responses. Further research is necessary to determine exactly how this reaction occurs and how it can be avoided. PMID:19223954

    Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery. PMID:27595088

    Objective: The aim of this study was to evaluate the efficacy and safety of ultrasound guided percutaneous sclerotherapy of symptomatic simple renal cysts with n-butyl cyanoacrylate (NBCA) and iodized oil mixture as an outpatient single session procedure. Materials and Methods: A total of ninety two patients with 100 symptomatic simple renal cysts (larger than 5 cm) were treated by ultrasound (US)-guided percutaneous aspiration and injection of NBCA and iodized oil mixture. The patients (68 men and 24 women, mean age, 42.4 ± 10.5 years) were treated with as out-patients. The volume of the treated cysts was calculated with periodic noncontrast enhanced CT examinations 3, 6 and 9, months after the procedure. The procedure was considered successful at follow-up CT when there was total ablation or greater than 80% reduction of size with resolution of symptoms, respectively. Failure was defined as less than 80% reduction and/or persistent symptoms. Results: The sclerotherapy was technically successful in all patients. The diameter of the cysts ranged between 5.5 and 13.5 cm (mean, 8.8 ± 1.4 cm), and 1.5 and 3.8 cm (mean, 2.1 ± 0.4 cm) before and after sclerotherapy, respectively (P < 0.001). Average diameter reduction was 83.7% during the follow-up period. The mean follow- up lasted 7.1 months (3–11 months). Flank pain resolved in 86 of 92 symptomatic patients (93.48%). In six patients, the symptoms decreased slightly. The procedure was successful in 98 of 100 cysts (98%), demonstrated by follow-up CT. The only two failed cyst was larger than 10 cm in diameter and don’t required any further treatment. We did not observe any procedure related complications. Conclusion: Ultrasound guided percutaneous sclerotherapy with NBCA and iodized oil mixture for management of symptomatic simple renal cysts was found to be a real time, effective, safe, well tolerated, alternative and simple technique that can be carried out by urologists as an outpatient procedure.

    The reconstructive options for large expansive cystic lesion affecting the jaws are many. The first stage of treatment may involve enucleation or marsupialization of the cyst. Attempted reconstruction of large osseous defects arising from the destruction of local tissue can present formidable challenges. The literature reports the use of bone grafts, free tissue transfer, bone morphogenic protein and reconstruction plates to assist in the healing and rehabilitation process. The management of huge mandibular cysts needs to take into account the preservation of existing intact structures, removal of the pathology and the reconstructive objectives which focus both on aesthetic and functional rehabilitation. The planning and execution of such treatment requires not only the compliance of the patient and family but also their assent as customers with a voice in determining their surgical destiny. The authors would like to report a unique case of a huge solitary bone cyst that had reduced the ramus, angle and part of the body of one side of the mandible to a pencil-thin-like strut of bone. A combination of decompression through marsupialization, serial packing, and the fabrication of a custom made obturator facilitated the regeneration of the myo-osseous components of the masticatory unit of this patient. Serial CT scans showed evidence of concurrent periosteal and endosteal bone formation and, quite elegantly, the regeneration of the first branchial arch components of the right myo-osseous masticatory complex. The microenvironmental factors that may have favored regeneration of these complex structures are discussed. PMID:27408457

    Fluid-fluid levels have commonly been reported to occur in aneurysmal bone cysts but have also been seen in telangiectatic osteosarcoma, chondroblastoma, and giant cell tumor of bone. The authors reviewed their experience with nine bone and three soft-tissue tumors that showed fluid-fluid levels on computed tomographic or magnetic resonance images. The bone tumors included fibrous dysplasia, simple bone cyst, recurrent malignant fibrous histiocytoma of bone, two classical osteosarcomas, and four aneurysmal bone cysts. The soft-tissue tumors included soft-tissue hemangioma and two synovial sarcomas. Except for aneurysmal bone cysts, these types of tumors have not been reported to be associated with fluid-fluid levels. Radiologic-pathologic correlation was available in seven patients; in all seven, the fluid-fluid levels indicated prior hemorrhage. The authors conclude that the presence of fluid-fluid levels in bone or soft-tissue tumors cannot be considered diagnostic of any particular tumor. PMID:2160676

    We present the case of a 46-year-old woman with no significant past medical history who developed left mid-thigh pain and fullness. Imaging demonstrated a mineralized soft-tissue mass, which increased in size during a year of monitoring, but retained a circumscribed appearance. The mass was located in the medial soft tissues of the thigh, separate from the bone on imaging studies, and this finding was confirmed during excision. The mass showed gross and microscopic features of an aneurysmal bone cyst. This diagnosis was supported by cytogenetic analysis revealing a t(17;17)(p13;q21) translocation corresponding to the USP6 and COL1A1 loci. Soft-tissue aneurysmal bone cyst is a rare entity, with fewer than 25 reports in the literature. Limited cytogenetic information about these tumors is available. To our knowledge, the USP6 and COL1A1 rearrangement has only previously been described in a pediatric soft-tissue aneurysmal bone cyst. We also discuss the differential diagnosis of ossifying soft-tissue lesions. PMID:26142538

    Fractures are a very important issue in a child's orthopedic pathology. Neglected a good amount of time, being considered "not too serious", or "rare", having better and faster healing methods and not leaving sequels, like in the case of adults, a child's fractures remain an important chapter of traumatology in general. Because of the raising prevalence of child osteoarticular traumas, as well as new less invasive treatment methods, this theme is always to date. The paper analyzes particular cases of bone fractures that appeared due to minor traumas, on bones with a high brittleness, localized especially on the long bones. Although these fractures on a pathological bone can be seen at all levels of the human skeleton, this paper focuses on fractures located in the proximal third part of the femur. A group of children admitted in the Pediatric Orthopedic Department of "M.S. Curie" Hospital-Bucharest with this diagnostic, were analyzed between 2009 and 2013. PMID:26664486

    The simultaneous occurrence of an aneurysmal bone cyst (ABC) on a zygomatic arch with bilateral inferior turbinate gasification is extremely rare, and no previous studies are available. Here we report the case of a 34-year-old Chinese Han female who presented with hyperplasia of the left maxillary bone for one and a half years. The patient was observed to have an ABC on the left zygomatic arch concomitant with bilateral inferior turbinate gasification, as indicated by X-ray computed tomography, contrast-enhanced computed tomography and three-dimensional maxillofacial reconstruction. The patient underwent surgical resection of the cyst, and no postoperative symptoms were observed during the 4 years of follow-up. The etiology of this case is considered to be associated with a gene abnormality. PMID:26893709

    A simple and effective modified ethanol precipitation-based protocol is described for the preparation of DNA from ancient human bones. This method is fast and requires neither hazardous chemicals nor special devices. After the powdering and incubating of the bone samples Dextran Blue was added as a carrier for removing the PCR inhibitors with selective ethanol precipitation. This method could eliminate the time-consuming separate decalcification step, dialysis, application of centrifugation-driven microconcentrators and the second consecutive PCR amplification. The efficiency of this procedure was demonstrated on ten 500–1200-year-old human bones from four different Hungarian burial sites. A mitochondrial specific primer pair was used to obtain sequence information from the purified ancient DNA. The PCR amplification, after our DNA extraction protocol, was successful from each of the 10 bone samples investigated. The results demonstrate that extraction of DNA from ancient bone samples with this new approach increases the success rate of PCR amplification. PMID:10871390

    Uremic osteodystrophy is an expected complication in subjects with chronic renal insufficiency. It develops gradually and progressively already during the conservative treatment and then during the dialysis treatment. It can present a wide histopathological spectrum including typical alterations (from osteitis fibrosa to osteomalacia and/or mixed lesions) or, more rarely, isolated bone lesions indicative of a brown tumor of the bone. These conditions must be clearly identified in the pretransplant phase, especially if a bone lesion indicative of a pathological condition possibly evolving into a neoplasm is detected fortuitously. We report the case of a 19-yr-old boy with renal insufficiency and candidate for a pre-emptive renal transplantation from a living donor, in whom the diagnosis of ABC of the pubic symphysis - asymptomatic and fortuitously detected while performing instrumental investigations - was suspected through the imaging studies (CT scan, MRI) and was confirmed by the histological examination. This made it possible to perform the renal transplant. The immunosuppressive treatment, which was subsequently administered, was based on steroids, calcineurin inhibitors (tacrolimus), and mycophenolate and did not determine any modification in the radiological aspect of the bone lesion, even after more than one yr from the transplant.

Clinical Presentation We describe a case of a 28-year-old woman who presented at 37 weeks of gestation with 3 months of gradually worsening vision, 10 months of proptosis, and restricted ocular motility on the left. Brain imaging revealed a multicystic enhancing mass measuring 5.9 × 5.3 × 3.7 cm, centered on the cribriform plate on the left, extending into the anterior cranial fossa superiorly as well as the left nasal cavity, maxillary, sphenoid, and frontal sinuses. Her clinical course is described in detail; 3-month postoperative imaging demonstrated no residual mass. Conclusion A literature review revealed five previous cases of ABCs associated with pregnancy. We report a rare case of a giant ABC of fibrous dysplasia involving the paranasal sinuses and anterior cranial fossa. We postulate on the possible influence of pregnancy on the clinical course.

    Epidermoid cysts are histologically benign, slow-growing congenital neoplasms of the central nervous system that may arise from retained ectodermal implants. The epidermoid lesions are generally caused during the 3(rd) to 5(th) week of gestation by an incomplete cleavage of the neural tissue from the cutaneous ectoderm, though it can also happen later in life due to introduction of skin elements by skin puncture, trauma or surgery. We present this unique case of a petromastoid epidermoid cyst associated with ipsilateral cerebellar abscesses, presenting 20 years after a penetrating trauma to the external auditory canal. Radical excision of both lesions and revision of the previous fistulous tract was performed. We present the diagnostic challenge and the operative treatment of this unique case, which to our knowledge is the first where an epidermoid cyst and an adjacent brain abscess occurred as a result of a single traumatic event.

    It has always been a challenge to reconstruct large bone gaps. The aim of this case report is to highlight the success of homologous maternal bone grafting in a large cystic lesion. A six and half years old boy presented to us with an aneurysmal bone cyst (ABC) of the right radius, not amenable to curettage. We excised the lesion in toto, which created an 11 cm bone loss. Considering the age of the patient, we reconstructed the bone gap with maternal fibular graft. Accordingly, 12 cm of fibular graft was harvested and fashioned to fit into the bone gap. It was fixed with an intramedullary K-wire. No cancellous graft was used in the procedure. The limb was kept in the above elbow cast till incorporation of the fibula was noted on the radiographs. Six months following surgery the skiagram showed that the fibula was incorporated. Mobilization of the elbow and wrist was started along with strengthening of the forearm muscles. K-wire was removed at nine months. At the latest follow up of 24 months, the fibula is fully incorporated, the child regained full range of motion and strength of elbow. We discuss the techniques adopted in this particular case along with the review of literature. PMID:27163107

This paper presents the particular case of two brothers, treated in our clinic for the same condition: solitary bone cyst of the proximal humerus. The two brothers were admitted with the same symptoms, the localization was the same. Because of the genetic studies regarding this condition, we think that it is an interesting aspect of this pathology. This study also tried to find the most appropriate approach in the treatment of these tumors. PMID:26664480

    Vegt, Paul; Muir, Jeffrey M; Block, Jon E

    2014-01-01

    The treatment of osteoporotic long bone fractures is difficult due to diminished bone density and compromised biomechanical integrity. The majority of osteoporotic long bone fractures occur in the metaphyseal region, which poses additional problems for surgical repair due to increased intramedullary volume. Treatment with internal fixation using intramedullary nails or plating is associated with poor clinical outcomes in this patient population. Subsequent fractures and complications such as screw pull-out necessitate additional interventions, prolonging recovery and increasing health care costs. The Photodynamic Bone Stabilization System (PBSS) is a minimally invasive surgical technique that allows clinicians to repair bone fractures using a light-curable polymer contained within an inflatable balloon catheter, offering a new treatment option for osteoporotic long bone fractures. The unique polymer compound and catheter application provides a customizable solution for long bone fractures that produces internal stability while maintaining bone length, rotational alignment, and postsurgical mobility. The PBSS has been utilized in a case series of 41 fractures in 33 patients suffering osteoporotic long bone fractures. The initial results indicate that the use of the light-cured polymeric rod for this patient population provides excellent fixation and stability in compromised bone, with a superior complication profile. This paper describes the clinical uses, procedural details, indications for use, and the initial clinical findings of the PBSS. PMID:25540600

    The following review investigates the term and concept of the globulomaxillary cyst as a correct clinico-pathological diagnosis to describe a so-called fissural cyst said to be caused by epithelial entrapment between the nasal and maxillary process. After analyzing the available literature it has to be concluded that neither from an embryologic nor from a clinical or pathohistological standpoint the term globulomaxillary cyst represents a real entity by itself. Therefore, globulomaxillary cysts have to be diagnosed alternatively after a thorough clinical, radiological and histological examination as other odontogenic cysts like dentigerous cysts or odontogenic keratocysts, odontogenic tumors like ameloblastoma, central giant cell tumors, solitary bone cysts, etc. PMID:16708524

    Cysts found on the ventral surface of the penis have been pathogenetically ascribed to defective embryologic closure of the median raphe, to anomalous developmental rests of the periurethral glands of Littre, and to the ectopic development of apocrine cystadenoma in the penile skin. This case reports a previously unrecognized but compelling pathogenesis for at least some ventral penile cysts, namely the anomalous congenital outgrowth of the entodermal urethral lining, giving rise to what is here designated as a urethroid cyst.

    Objectives This study aimed to develop a scoring system to predict the survival time of patients with bone metastases after radiation therapy (RT). The scoring system can guide physicians to a better selection of appropriate treatment regimens. Materials and Methods The medical records of 125 patients with bone metastases treated with RT between January 2007 and September 2010 were reviewed retrospectively. Fifteen potential prognostic factors were investigated: sex, age, Karnofsky performance score (KPS), type of primary tumor, resection of tumor before bone metastases, interval between primary tumor diagnosis and diagnosis of bone metastases, Carcinoembryonic Antigen(CEA), lung metastases before bone metastases, liver metastases before bone metastases, brain metastases before bone metastases, stage, T, N, M, and degree of cellular differentiation. Results In an univariate analysis, 10 factors were significantly associated with survival time after bone metastasis: sex, KPS, breast cancer, esophageal cancer, colorectal cancer, interval between tumor diagnosis and diagnosis of bone metastases, CEA, lung metastases before bone metastases, T-staging, and differentiation. In a multivariate analysis, 7 factors were found to be significant: sex, KPS, esophageal cancer, colorectal cancer, interval between tumor diagnosis and diagnosis of bone metastases, T-staging, and differentiation. The median survival of all patients with bone metastases after RT was 14.1 months. There were significant differences in the median survival of patients with bone metastases after RT of 4.9 months, 10.5 months, and 29.7 months in groups 1, 2, and 3, respectively (P<0.001). Conclusion According to this scoring system, the survival time of patients after bone metastasis can be estimated. PMID:27438606

    The incidence of aneurysmal bone cysts is 0.14 cases per 100,000 individuals. Parosteal aneurysmal bone cysts are the least prevalent subtype and represent 7% of all aneurysmal bone cysts. We present the case of a 38-year-old male patient with pain and bulging in his right arm for eight months. He had previously been diagnosed as presenting giant-cell tumor, but his slides were reviewed and his condition was then diagnosed as parosteal aneurysmal bone cyst. The patient was treated with corticosteroid and calcitonin infiltration into the lesion and evolved with clinical and radiological improvement within the first five weeks after the operation.

    Fluid-fluid levels in bone tumors have been described in aneurysmal bone cysts and other cystic tumors of bones and soft tissue tumors. We experienced three bone tumors (simple bone cyst, bone metastasis, and osteosarcoma) and three soft tissue tumors (fibrosarcoma, two cases of cavernous hemangioma) that showed fluid-fluid levels on MR, and investigated their cause. Causes included blood in the cystic spaces, hemorrhage in the tumor, the telangiectatic component of the osteosarcoma, and the cavernous component of the hemangioma. No specific diagnosis could be made based on the finding of fluid-fluid levels. We conclude that fluid-fluid levels on MR are rather nonspecific findings in bone and soft tissue tumors and that the diagnosis should be made on the basis of other radiological and clinical findings.

    Glandular odontogenic cyst (GOC) is a rare and uncommon jaw bone cyst of odontogenic origin described in 1987 by Gardener et al. as a distinct entity. It is a cyst having an unpredictable, potentially aggressive behavior, and has the propensity to grow in large size with relatively high recurrence rate. It poses a diagnostic challenge as it can be clinically and histopathologically confused with lateral periodontal cyst, botryoid odontogenic cyst, radicular and residual cysts with mucous metaplasia, and low-grade mucoepidermoid carcinoma. The present case report describes GOC in both male and female patients with intra-oral swelling following extraction of 36 and 46, respectively. Careful histopathological examination is needed to diagnose GOC, and a careful long-term follow-up is advocated. PMID:27134453

    There is little information in the literature concerning the role of bone scanning in benign bone neoplasms except for sporadic reports. Since the advent of 99mTc-polyphosphate, bone imaging has proven feasible and useful in locating the cause of bone pain, such as in osteoid osteomas, which are not always radiologically apparent, and in evaluating whether or not a radiologic lesion is indeed benign and solitary. Blood-pool images are particularly important in neoplastic disease, since the absence of hyperemia in the immediate postinjection period favors the diagnosis of a benign neoplasm, as does low-grade uptake on the delayed study. The scan, including pinhole magnification images, is especially valuable in diagnosing lesions in the spine and pelvis, which are poorly seen radiologically. We have studied various types of benign bone tumors, including simple and aneurysmal bone cysts, fibrous cortical defects, and nonossifying fibromas, all of which had minimal or no increased uptake of the radiopharmaceutical, unless traumatized. Although osteochondromas and enchondromas showed varied accumulation of activity, the scan was useful in differentiating these from sarcomatous lesions. All osteoid osteomas demonstrated marked activity, and could be accurately located preoperatively, as could the extent of fibrous dysplasia. The bone scan in the reticuloses also showed abnormal accumulation of activity, and aided in arriving at the prognosis and treatment of histiocytic bone lesions. PMID:1082170

    An apparent causal association between crizotinib treatment and renal cyst development emerged during clinical trials in anaplastic lymphoma kinase (ALK)-positive non–small cell lung cancer (NSCLC). Serious adverse event (SAE) reports of renal cysts from a safety database of 1375 patients from four clinical trials were reviewed. A blinded, retrospective, independent radiologic review (IRR) was performed using scans from patients on study for ≥6 months in three clinical trials; risk factors for renal cyst development were assessed. Among 17 patients with renal cysts reported as SAEs, evidence of invasion into adjacent structures was noted in seven patients, with no evidence of malignancy found. These patients generally did not require dose reductions, none required permanent crizotinib discontinuation due to this AE, and most continued treatment with clinical benefit. In the blinded IRR, among 255 crizotinib-treated patients, 22%, 3%, and 2% had preexisting simple cysts, complex cysts, or both, respectively. At the 6-month tumor assessment, 9% of all patients had acquired new cysts, and 2% of patients with preexisting cysts had developed new cysts and enlargements (>50%) of preexisting simple cysts. Asians appeared to have an increased risk of developing new cysts on treatment; Koreans in particular had 5.18 times higher odds of developing cysts than non-Asians (95% confidence interval, 1.51–17.78; P = 0.05). Crizotinib treatment appears to be associated with an increased risk of development and progression of renal cysts in patients with ALK-positive NSCLC. While close monitoring is recommended, dosing modification was not generally necessary, allowing patients to remain on crizotinib treatment. PMID:25756473

    This review brings the total number of biliary cysts reported in the world literature to 955. Eighty-one per cent of patients are females and 61% were discovered before age ten. The classical triad of right upper quadrant pain, right upper quandrant mass, and juandice is present in 38% of cases. The duration of symptoms prior to diagnosis ranged from less than one week to more than 40 years. The etiology is multifaceted and evidence of the existence of both acquired and congenital cysts is presented. The most useful diagnostic tool is fiberoptic endoscopy with retrograde contrast injection of the common bile duct and pancreatic duct. The incidence of biliary carcinoma in patients with biliary cysts is found to be 2.5%; 24 cases have been reported. Considerable controversy has existed concerning the best operative procedure for biliary cysts; no treatment or medical treatment yielding a 97% mortality rate. In an analysis of 235 patients presented since 1968 with an average followup of 5.2 years, the best procedure appears to be excision with either choledochocholedocostomy or Roux-en-Y hepaticojejunostomy. The operative mortality for all procedures is now 3 to 4%. PMID:1103760

    Botryoid odontogenic cyst (BOC) is considered to be a polycystic variant of the lateral periodontal cyst (LPC) as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

    Injectable gel systems, for the purpose of bone defect reconstruction, have many advantages, such as controlled flowability, adaptability to the defect site, and increased handling properties when compared to the conventionally used autologous graft, scaffolds, hydroxyapatite blocks, etc. In this work, nanohydroxyapatite (nHAp) incorporated chitin-poly(ε-caprolactone) (PCL) based injectable composite microgels has been developed by a simple regeneration technique for bone defect repair. The prepared microgel systems were characterized using scanning electron microscope (SEM), Fourier transformed infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The composite microgel, with the incorporation of nHAp, showed an increased elastic modulus and thermal stability and had shear-thinning behavior proving the injectability of the system. The protein adsorption, cytocompatibility, and migration of rabbit adipose derived mesenchymal stem cells (rASCs) were also studied. Chitin-PCL-nHAp microgel elicited an early osteogenic differentiation compared to control gel. The immunofluorescence studies confirmed the elevated expression of osteogenic-specific markers such as alkaline phosphatase, osteopontin, and osteocalcin in chitin-PCL-nHAp microgels. Thus, chitin-PCL-nHAp microgel could be a promising injectable system for regeneration of bone defects which are, even in deeper planes, irregularly shaped and complex in nature. PMID:25893690

    Bone marrow stromal cells (MSCs) can be differentiated into neuronal and glial-like cell types under appropriate experimental conditions. However, previously reported methods are complicated and involve the use of toxic reagents. Here, we present a simplified and nontoxic method for efficient conversion of rat MSCs into neurospheres that express the neuroectodermal marker nestin. These neurospheres can proliferate and differentiate into neuron, astrocyte, and oligodendrocyte phenotypes. We thus propose that MSCs are an emerging model cell for the treatment of a variety of neurological diseases.

    Introduction: Echinococcosis is a parasitic and zoonotic disease of animals and humans. The cause is Echinococcus granulosus and occasionally, Echinococcus multilocularis. Hydatid cysts are mostly seen in the liver and lungs, although almost all organs and systemscan be involvement. Hydatid cysts seen with bone involvement comprise approximately 3% of all hydatid cysts. Even if a long period of survey is possible, it is still difficult to eradicate the disease and effect a cure. Case Presentation: In this study, an evaluation was made of a patient referred at Yozgat State Hospital Orthopedics and Traumatology Polyclinic with complaints of pain in her left thigh close to the knee. After examinations of plain radiographs, computerized tomography, magnetic resonance images, and blood parameters, a diagnosis was made of left femoral intramedullary hydatid cyst from excised intraoperative material. Throughout a 6-month follow-up period, there was no recurrence and functional results were good. Conclusions: Based on this report (of a patient presented with an intramedullary cyst in the long bones), the primary bone hydatid cyst disease should be kept in mind and be investigated in the differential diagnosis.

    Dentigerous cysts are uncommon, yet are being reported with increasing frequency in the veterinary literature. Dentigerous cysts are a type of benign odontogenic cyst associated with impacted teeth, most commonly the mandibular first premolar tooth. Significant bone destruction can occur secondary to the expansion of a dentigerous cyst. The expanding cyst can lead to pathology of neighboring teeth, which can include external root resorption or pulpitis. Intraoral dental radiographs are imperative to properly assess the presence and extent of a dentigerous cyst, as well as the status of the neighboring teeth. This case report describes treatment for dentigerous cyst including cyst lining curettage, mandibular bone regeneration, and endodontic therapy for a canine tooth with irreversible pulpitis.

    Dermoid cysts are a very rare entity of intracranial tumours. The traumatic or non-traumatic rupture of the cyst wall is a serious complication that can be treated surgically or conservatively depending on the clinical symptoms. However, more common entities have to be considered as a differential diagnosis. We report on a female patient who was admitted with complaints of significant, prolonged headache and diffuse pain. Analysis of her blood and cerebrospinal fluid indicated no clear pathology. A CT examination of the head revealed a ruptured dermoid cyst adjacent to the left sphenoidal bone. An additional MRI was conducted to confirm the CT findings and rule out an intracranial ischemia or vasospasms. A conservative therapy was scheduled and the patient recovered well. Using current imaging techniques, especially magnetic resonance imaging, it is possible to identify a ruptured dermoid cyst by its pathognomonic signal behavior and rule out potentially life threatening complications.

    The shape of tissues arises from a subtle interplay between biochemical driving forces, leading to cell growth, division and extracellular matrix formation, and the physical constraints of the surrounding environment, giving rise to mechanical signals for the cells. Despite the inherent complexity of such systems, much can still be learnt by treating tissues that constantly remodel as simple fluids. In this approach, remodelling relaxes all internal stresses except for the pressure which is counterbalanced by the surface stress. Our model is used to investigate how wettable substrates influence the stability of tissue nodules. It turns out for a growing tissue nodule in free space, the model predicts only two states: either the tissue shrinks and disappears, or it keeps growing indefinitely. However, as soon as the tissue wets a substrate, stable equilibrium configurations become possible. Furthermore, by investigating more complex substrate geometries, such as tissue growing at the end of a hollow cylinder, we see features reminiscent of healing processes in long bones, such as the existence of a critical gap size above which healing does not occur. Despite its simplicity, the model may be useful in describing various aspects related to tissue growth, including biofilm formation and cancer metastases. PMID:26018964

    In the present study, we had introduced polyurethane (PU) nanofibers that contain hydroxyapatite (HAp) nanoparticles (NPs) as a result of an electrospinning process. A simple method that does not depend on additional foreign chemicals had been employed to synthesize HAp NPs through the calcination of bovine bones. Typically, a colloidal gel consisting of HAp/PU had been electrospun to form nanofibers. In this communication, physiochemical aspects of prepared nanofibers were characterized by FE-SEM, TEM and TEM-EDS, which confirmed that nanofibers were well-oriented and good dispersion of HAp NPs, over the prepared nanofibers. Parameters, affecting the utilization of the prepared nanofibers in various nano-biotechnological fields have been studied; for instance, the bioactivity of the produced nanofiber mats was investigated while incubating in simulated body fluid (SBF). The results from incubation of nanofibers, indicated that incorporation of HAp strongly activates the precipitation of the apatite-like particles, because of the HAp NPs act as seed, that accelerate crystallization of the biological HAp from the utilized SBF.

    Orthokeratinised odontogenic cyst (OOC) denotes the odontogenic cyst that microscopically has an orthokeratinised epithelial lining. OOC is characterised by a less-aggressive behaviour and a low rate of recurrence. This report describes a case of OOC involving posterior part of the mandible that mimicked periapical cyst in a 14-year-old boy. The initial clinical diagnosis was given as periapical cyst based on the clinical and radiographical features. Enucleation of the cyst was performed and the specimen was sent for histopathological examination. A definite diagnosis of OOC was made by histopathological examination of the biopsy specimen. This case emphases on including OOC in the differential diagnosis of radiolucencies occurring in the periapical region of non-vital tooth. PMID:24099763

    The soybean cyst nematode (SCN), Heterodera glycines, causes economically significant damage to soybeans (Glycine max) in many parts of the world. The cysts of this nematode can remain quiescent in soils for many years as a reservoir of infection for future crops. To investigate bacterial communities associated with SCN cysts, cysts were obtained from eight SCN-infested farms in southern Ontario, Canada, and analyzed by culture-dependent and -independent means. Confocal laser scanning microscopy observations of cyst contents revealed a microbial flora located on the cyst exterior, within a polymer plug region and within the cyst. Microscopic counts using 5-(4,6-dichlorotriazine-2-yl)aminofluorescein staining and in situ hybridization (EUB 338) indicated that the cysts contained (2.6 ± 0.5) × 105 bacteria (mean ± standard deviation) with various cellular morphologies. Filamentous fungi were also observed. Live-dead staining indicated that the majority of cyst bacteria were viable. The probe Nile red also bound to the interior polymer, indicating that it is lipid rich in nature. Bacterial community profiles determined by denaturing gradient gel electrophoresis analysis were simple in composition. Bands shared by all eight samples included the actinobacterium genera Actinomadura and Streptomyces. A collection of 290 bacteria were obtained by plating macerated surface-sterilized cysts onto nutrient broth yeast extract agar or on actinomycete medium. These were clustered into groups of siblings by repetitive extragenic palindromic PCR fingerprinting, and representative isolates were tentatively identified on the basis of 16S rRNA gene sequence. Thirty phylotypes were detected, with the collection dominated by Lysobacter and Variovorax spp. This study has revealed the cysts of this important plant pathogen to be rich in a variety of bacteria, some of which could presumably play a role in the ecology of SCN or have potential as biocontrol agents.

In a retrospective study, we found 9 such cases, accounting for 5.5% of a series of 163 consecutive mediastinal nonneoplastic cysts operated in our institution. These cysts occurred in 9 women aged 40 to 58 years (mean, 50.6 years). These women often had overweight (n=4) or various gynecologic history (n=5). Cysts were paravertebral (n=8) or prevertebral (n=1). They were initially classified as bronchogenic or unspecified benign serous cysts. Their diameter measured 1.3 to 5 cm. Their thin wall contained smooth muscle. They were lined by a simple cylindrical or cuboidal, nonmucinous, and often ciliated epithelium resembling uterine tubal epithelium. This epithelium expressed cytokeratin 7, epithelial membrane antigen and estrogen and progesterone receptors. It was negative for cytokeratin 5/6. In the same series, there were 66 bronchogenic cysts, 6 being paravertebral. In conclusion, cysts with müllerian differentiation account for a small proportion of mediastinal cysts and have a usual but nonspecific paravertebral location. PMID:18022126

    Ganglion cysts are tumor-like lesions in the soft tissues, generated by mucoid degeneration of the joint capsule, tendon or tendon sheaths on the dorsum of hand, wrist and foot. However, an intratendinous origin for a ganglion cyst is extremely rare. During dissection of the popliteal fossa, a cyst of 2.5 cm×2 cm×0.5 cm was observed in the tendon of right semimembranosus, 3.5 cm above the insertion of the muscle. Contrast X-ray revealed the cyst as not communicating with the knee joint or any adjacent bursae. Histopathological examination confirmed the diagnosis of ganglion cyst. PMID:25276481

    Background There has been no consensus on the optimal treatment of symptomatic sacral perineural cysts. Most previous reports concerning the management methods were either sporadic case reports or a series of limited cases. This study is to further optimize the management for patients with symptomatic sacral perineural cysts by analyzing the outcomes of a cohort of patients who were treated with different strategies. Methods and Findings We reviewed the outcomes of 15 patients with symptomatic sacral perineural cysts who were managed by three different modalities from 1998 through 2010. Six patients underwent microsurgical cyst fenestration and cyst wall imbrication. Seven patients underwent a modified surgical procedure, during which the cerebrospinal fluid leak aperture was located and repaired. Two patients were treated with medication and physical therapy. Outcomes of the patients were assessed by following up (13 months to 10 years). All of the six patients treated with microsurgical cyst fenestration and cyst wall imbrication experienced complete or substantial relief of their preoperative symptoms. However, the symptoms of one patient reappeared eight months after the operation. Another patient experienced a postoperative cerebrospinal fluid leakage. Six of the seven patients treated with the modified surgical operation experienced complete or substantial resolution of their preoperative symptoms, with only one patient who experienced temporary worsening of his preoperative urine incontinence, which disappeared gradually one month later. No new postoperative neurological deficits, no cerebrospinal fluid leaks and no recurrence were observed in the seven patients. The symptoms of the two patients treated with conservative measures aggravated with time. Conclusions Microsurgical operation should be a treatment consideration in patients with symptomatic sacral perineural cysts. Furthermore, the surgical procedure with partial cyst removal and aperture repair

    Highlights: •We validate a simple and fast method of quantification of in vitro mineralization. •Fluorescently labeled agents can detect calcium deposits in the mineralized matrix of cell cultures. •Fluorescent signals of the probes correlated with Alizarin Red S staining. -- Abstract: Alizarin Red S staining is the standard method to indicate and quantify matrix mineralization during differentiation of osteoblast cultures. KS483 cells are multipotent mouse mesenchymal progenitor cells that can differentiate into chondrocytes, adipocytes and osteoblasts and are a well-characterized model for the study of bone formation. Matrix mineralization is the last step of differentiation of bone cells and is therefore a very important outcome measure in bone research. Fluorescently labelled calcium chelating agents, e.g. BoneTag and OsteoSense, are currently used for in vivo imaging of bone. The aim of the present study was to validate these probes for fast and simple detection and quantification of in vitro matrix mineralization by KS483 cells and thus enabling high-throughput screening experiments. KS483 cells were cultured under osteogenic conditions in the presence of compounds that either stimulate or inhibit osteoblast differentiation and thereby matrix mineralization. After 21 days of differentiation, fluorescence of stained cultures was quantified with a near-infrared imager and compared to Alizarin Red S quantification. Fluorescence of both probes closely correlated to Alizarin Red S staining in both inhibiting and stimulating conditions. In addition, both compounds displayed specificity for mineralized nodules. We therefore conclude that this method of quantification of bone mineralization using fluorescent compounds is a good alternative for the Alizarin Red S staining.

    Single energy X-ray imaging, due to its low cost and flexibility, is one of the most used and common technique to assess bone state and bone remodeling over time. Standardized X-ray images are needed to compare sets of radiographs for semi-quantitative analyses of tissue remodeling. However, useful mathematical modeling for the analysis of high level radiographic images are not easily available. In order to propose a useful evaluation tool to a wide clinical scenario, we present an innovative calibration algorithm for a semi-quantitative analysis of non-standardized digitized X-ray images. For calibration on a unique standardization scale, three time invariant regions (ROI) of radiographs were selected and analyzed. The accuracy of the normalization method for X-ray films was successfully validated by using an aluminum step wedge for routine X-ray exposures as tool to standardize serial radiographs (Pearson correlation test: R(2) = 0.96). This method was applied to investigate the progression of the new bone deposition within ceramic scaffolds used as osteoconductive substitute in large bone defects taking advantage of a large animal model. This innovative image-processing algorithm allowed the identification and semi-quantification of the bone matrix deposited within the implant. The osteo-integration at the bone-implant interface was also investigated. A progressively increasing bone tissue deposition within the porous bioceramic implant and a progressive osteo-integration was observed during the 12 months of the trial. PMID:16007593

    Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. We report a case of a 42 year-old, right-handed female, who presented with pain of the right wrist following a fall on the palm of the hand. Clinical study revealed a moderate swelling over the mid-section of the palmar face and pain through extreme ranges of motion of the wrist. Plain radiographs and CT-scan of the wrist have revealed an intraosseous ganglion cyst of the lunate bone. Curetting-filling by Kuhlman's vascularized radial bone graft allowed a good functional recovery. The clinical, radiological and therapeutic aspects are discussed. PMID:27321303

    Dermoid cysts are malformations that are rarely seen in the oral cavity. An intraoral dermoid cyst grows slowly, but may enlarge and interfere with deglutition and speech, or can pose a critical risk to the airway and therefore require immediate surgical intervention. Dermoid cysts may develop above or below the mylohyoid muscle, causing a submental or submandibular swelling. Surgical excision is the treatment of choice and recurrence is rare. An intraoral approach for the treatment of large lesions presenting above the mylohyoid muscle provides good cosmetic and functional results. We report a case of a 26-year-old female who developed an epidermoid cyst presenting as a large sublingual swelling causing speech and swallowing difficulties. The lesion was surgically excised using an intraoral approach. Microscopic examination revealed a dermoid cyst of the epidermoid type. This case shows that dermoid cysts may be successfully diagnosed and managed using a series of simple yet effective clinical procedure. PMID:25298725

    The glandular odontogenic cyst (GOC) is a rare lesion with odontogenic origin. It shows a propensity for recurrence revealed in 30% of all case. This investigation reports a case of recurrent GOC in a 35-year-old female in the anterior region of the maxilla, which is uncommon and discusses about IHC finding, surgical methods, and differential diagnosis. Under general anesthesia, peripheral bone ostectomy via large round bur for removal of remaining epithelium of the cyst wall was done. Finally liquid nitrogen was used to remaining bone. This article recommends that soft tissue adjacent to the cortical bone perforation should be excised, as well as peripheral bone ostectomy by large round bur for removal of remaining epithelium of the cyst and liquid nitrogen application to the bony cavity. Because of high recurrence rate of the lesion close follow up of the patients is needed. PMID:26351478

    Context: Popliteal synovial cysts, also known as Baker’s cysts, are commonly found in association with intra-articular knee disorders, such as osteoarthritis and meniscus tears. Histologically, the cyst walls resemble synovial tissue with fibrosis evident, and there may be chronic nonspecific inflammation present. Osteocartilaginous loose bodies may also be found within the cyst, even if they are not seen in the knee joint. Baker’s cysts can be a source of posterior knee pain that persists despite surgical treatment of the intra-articular lesion, and they are routinely discovered on magnetic resonance imaging scans of the symptomatic knee. Symptoms related to a popliteal cyst origin are infrequent and may be related to size. Evidence Acquisition: A PubMed search was conducted with keywords related to the history, diagnosis, and treatment of Baker’s cysts—namely, Baker’s cyst, popliteal cyst, diagnosis, treatment, formation of popliteal cyst, surgical indications, and complications. Bibliographies from these references were also reviewed to identify related and pertinent literature. Study Design: Clinical review. Level of Evidence: Level 4. Results: Baker’s cysts are commonly found associated with intra-articular knee disorders. Proper diagnosis, examination, and treatment are paramount in alleviating the pain and discomfort associated with Baker’s cysts. Conclusion: A capsular opening to the semimembranosus–medial head gastrocnemius bursa is a commonly found normal anatomic variant. It is thought that this can lead to the formation of a popliteal cyst in the presence of chronic knee effusions as a result of intra-articular pathology. Management of symptomatic popliteal cysts is conservative. The intra-articular pathology should be first addressed by arthroscopy. If surgical excision later becomes necessary, a limited posteromedial approach is often employed. Other treatments, such as arthroscopic debridement and closure of the valvular mechanism

    Splenic cysts were found, incidentally, in eight children during the past nine years (1987-1995) in Taipei Municipal Women's and Children's Hospital. Five of the children were boys and three were girls. The age at diagnosis ranged from 8 to 15 years. Evidence of possible splenic cyst development was found initially by ultrasonography; six patients received further evaluation with computerized tomography (CT); one patient received radionuclide scanning. The cysts ranged from 2 cm to 14 cm in diameter. Four of the patients received surgical treatment (three partial splenectomy and one total splenectomy) because of huge splenic cysts (diameter > 10 cm). Subsequent pathological examination revealed that all cysts had epithelial cell lining in the cyst wall, meaning they were all congenital in origin. The remaining four cases were followed up at the Out-patient Clinic here. All cases had a benign clinical course. PMID:9066189

    A case of intravesical hydatid cyst is reported. The cyst was completely evacuated cystoscopically with intravesical instillation of a scolicidal agent (hydrogen peroxide) to destroy scolices and daughter cysts. The postoperative course was uneventful, and follow-up did not show evidence of recurrence. Because this is the first case, to our knowledge, to be reported, little is known about the nonoperative management of such hydatid localization. A recommendation is made, however, to adopt this minimally invasive procedure. PMID:16286147

    OBJECTIVE: To describe the prevalence and characteristics of pineal cysts found on MRI in children. METHODS: This is a retrospective monocentric study of all brain magnetic resonance imaging (MRI) examinations performed under the same technical conditions for checking the idiopathic nature of short stature (ISS group, n = 116) and for the investigation of central precocious puberty (CPP) over a 3-year period (n = 56). Dimensions, wall and septal thickness, number of locules, signal intensity, and the presence of a solid component were analysed. Ten of 19 cysts were re-evaluated (follow-up interval 4-28 months). The prevalence of the pineal cysts was compared between the two groups using χ2 and Fisher's exact tests, and a significance threshold of p < 0.05. RESULTS: The prevalence of cysts was comparable in the two groups, CPP (10.7%) and ISS (11.2%). Cyst characteristics were similar in the two groups and 74% had thin septations. None of the cysts changed on follow-up. None of the children with pineal cysts exhibited neurological signs. CONCLUSION: Benign pineal cysts are a common finding in young children. High-resolution MRI demonstrates that these cysts are often septated. This pattern is a normal variant and does not require follow-up MR imaging or IV contrast media. PMID:22347985

    Spinal extradural arachnoid cyst (SEAC) is a rare disease and uncommon cause of compressive myelopathy. The etiology remains still unclear. We experienced 2 cases of SEACs and reviewed the cases and previous literatures. A 59-year-old man complained of both leg radiating pain and paresthesia for 4 years. His MRI showed an extradural cyst from T12 to L3 and we performed cyst fenestration and repaired the dural defect with tailored laminectomy. Another 51-year-old female patient visited our clinical with left buttock pain and paresthesia for 3 years. A large extradural cyst was found at T1-L2 level on MRI and a communication between the cyst and subarachnoid space was illustrated by CT-myelography. We performed cyst fenestration with primary repair of dural defect. Both patients' symptoms gradually subsided and follow up images taken 1-2 months postoperatively showed nearly disappeared cysts. There has been no documented recurrence in these two cases so far. Tailored laminotomy with cyst fenestration can be a safe and effective alternative choice in treating SEACs compared to traditional complete resection of cyst wall with multi-level laminectomy.

    Ti15Zr4Nb4Ta and Ti29Nb13Ta4.6Zr, which do not contain the potentially cytotoxic elements V and Al, represent a new generation of alloys with improved corrosion resistance, mechanical properties, and cytocompatibility. Recently it has become possible for the apatite forming ability of these alloys to be ascertained by treatment with alkali, CaCl2, heat, and water (ACaHW). In order to confirm the actual in vivo bioactivity of commercially pure titanium (cp-Ti) and these alloys after subjecting them to ACaHW treatment at different temperatures, the bone bonding strength of implants made from these materials was evaluated. The failure load between implant and bone was measured for treated and untreated plates at 4, 8, 16, and 26 weeks after implantation in rabbit tibia. The untreated implants showed almost no bonding, whereas all treated implants showed successful bonding by 4 weeks, and the failure load subsequently increased with time. This suggests that a simple and economical ACaHW treatment could successfully be used to impart bone bonding bioactivity to Ti metal and Ti-Zr-Nb-Ta alloys in vivo. In particular, implants heat treated at 700 °C exhibited significantly greater bone bonding strength, as well as augmented in vitro apatite formation, in comparison with those treated at 600 °C. Thus, with this improved bioactive treatment process these advantageous Ti-Zr-Nb-Ta alloys can serve as useful candidates for orthopedic devices. PMID:20883837

    1985-01-01

    The author, who in 1955 had published a thesis on the remote results of the treatment of bone cysts on children and teenagers, decided to go back to that subject 30 years later. He was able to gather 203 observations (mostly from Paris Hospitals) followed up for at least 2 years (some of them for more than 30 years) and in 15 of those cases no treatment had been undergone. The pathogenesis of the bone cyst is still unknown, but there are obvious connections between the cystic socket and the vascular metaphysis. Rigault and Padovani had the opportunity to observe, during some injections of contrasting preparation in the humeral cysts that the liquid went quickly into the auxiliary venous system. The bone cysts appear in the spongy tissue of bone metaphysis in full movement. The author thinks that the cystic sockets are made by the gathering of osteolytic bubbles and that the protrusions inside the bone are nothing, but the former limits of those bubbles. The evolution does not always follow the classical pattern and one can often observe--in particular in the humeral localisation--lytic outbreaks on a cyst which growth seemed stationary or on the way of recovery. Those outbreaks with specific evolution bring about either an extension of the socket or the appearance of a new geode. The recovery (total or partial) usually comes after septation of the cavity. It is only at the end of the growth that one can be sure of the stabilization of the remaining lesions. As for the spontaneous disappearance of the cavity, it can take years. Considering the ever encouraging evolution of the bone cysts, one must always be very careful in judging the efficacy of the different treatments that are recommended. The different traumatisms (fractures, surgery or corticoids) bring forth perturbations in the bone socket, according to a pattern that we do not know well. The result is often paradoxical: one bone cyst which was apparently stabilized will awake and spread; another, partially

    The dentigerous cyst is a developmental odontogenic cyst, accounting for 10% of all cysts of the jaws. The treatment options are decompression, marsupialization, or enucleation regarding the features of the lesions. In this article, a case of a 17-year-old adolescent girl having a large mandibular dentigerous cyst associated with an unerupted third molar is presented. The treatment is composed of decompression for 6 months and enucleation. Decompression and enucleation are a predictable choice in the treatment of large cysts. Radiologic evaluation is mandatory to decide for the appropriate time for the removal of the decompression stents, the enucleation time, and also for the evaluation of the adequate new bone formation for implant placement. The present case emphasizes the success of a conservative approach in the management of a large dentigerous cyst in a young patient and also the maintenance of the new bone formation without using any graft materials for the placement of dental implants.

    Intraspinal extradural synovial cysts are quite common in the lumbar spine. With respect to clinical presentation and surgical treatment, juxta-facet cysts (ganglion and synovial cysts) share identical characteristics and results. Nowadays, current treatment strategies of intraspinal juxta-facet cysts continue to inspire controversy regarding appropriate surgical approaches, and include many technical options. The purpose of this report is to illustrate the advantage of minimally invasive approaches in 3 cases of lumbar synovial cysts. We performed a small flavectomy in the 1st case, a transarticular partial facectomy, followed by etherologous bone graft fusion in the 2nd case, and a flavectomy and partial facectomy in the 3rd case. In our cases, a microsurgical approach to lumbar synovial cysts yielded to complete excision of the lesions and excellent pain relief, with early mobilization and hospital discharge of the patients. In our opinion, minimally invasive approaches and microsurgical excision of lumbar juxta-facet cysts are advantageous over conventional lumbar laminectomy because they reduce later development of segmental instability at the operative level, and therefore a less invasive strategy for intraspinal synovial cysts removal should be recommended.

    Arachnoid cysts are benign congenital cerebrospinal fluid collections, usually asymptomatic and diagnosed incidentally in children or adolescents. They may become symptomatic after enlargement or complications, frequently presenting with symptoms of intracranial hypertension. We report an unusual case of progressive refractory headache in an adult patient due to an arachnoid cyst spontaneous rupture. Although clinical improvement occurred with conservative treatment, the subdural hygroma progressively enlarged and surgical treatment was ultimately needed. Spontaneous rupture is a very rare complication of arachnoid cysts. Accumulation of cerebrospinal fluid accumulation in the subdural space causes sustained intracranial hypertension that may be life-threatening and frequently requires surgical treatment. Patients with arachnoid cysts must be informed on their small vulnerability to cyst rupture and be aware that a sudden and severe headache, especially if starting after minor trauma or a Valsalva manoeuvre, always requires medical evaluation.

    Four patients with splenic masses were operated upon and found to have epidermoid cysts of the spleen, a rare lesion comprising less than 10% of benign, nonparasitic splenic cysts. The patients were young and had vague, non-specific symptoms which were related to the size of the slowly enlarging splenic mass. Three patients had palpable masses. Contrast gastrointestinal studies and intravenous urography will help exclude mass lesions of the gastrointestinal or genitourinary tract. Sonar scan may confirm the cystic nature of the lesion and localize it to the spleen. A review of 42,327 autopsy records at the Los Angeles County--University of Southern California Medical Center revealed 32 benign splenic cysts found incidentally at autopsy. Hemorrhage, infection, rupture, and rarely, malignant change are complications of splenic cysts. Splenectomy is recommended to eliminate the symptoms produced by the cyst and prevent the potential complications. Images Fig. 1. Fig. 2. Fig. 3. Fig. 4. Fig. 5. Fig. 6. PMID:637577

    Ganglion cysts are soft tissue swellings occurring most commonly in the hand or wrist. Apart from swelling, most cysts are asymptomatic. Other symptoms include pain, weakness, or paraesthesia. The two main concerns patients have are the cosmetic appearance of the cysts and the fear of future malignant growth. It has been shown that 58% of cysts will resolve spontaneously over time. Treatment can be either conservative or through surgical excision. This review concluded that nonsurgical treatment is largely ineffective in treating ganglion cysts. However, it advised to patients who do not surgical treatment but would like symptomatic relief. Compared to surgery, which has a lower recurrence rate but have a higher complication rate with longer recovery period. It has been shown that surgical interventions do not provide better symptomatic relief compared to conservative treatment. If symptomatic relief is the patient's primary concern, a conservative approach is preferred, whilst surgical intervention will decrease the likelihood of recurrence. PMID:24967120

We report and describe the first two unique cases of primary epidermoid cysts arising in the mastoid bone. Of the two cases, one presented with progressive headache and imbalance and the other with unilateral hearing loss and tinnitus. Both cases needed CT and MRI scans and needed surgical management. We review the clinical presentations, histology, pathogenesis, radiological findings and management of these challenging cases. The diagnosis of an epidermoid cyst is based on clinical presentation, physical examination and especially the radiological, histological and intraoperative findings. Total removal of the lesion along with its capsule is recommended to prevent recurrence and to allow for a good long-term prognosis. PMID:25958160

    Ganglion cysts are common pseudocystic masses, whereas those arising from the temporomandibular joint (TMJ) are rare entities. We report a case of ganglion cyst of the right TMJ with symptomatic bilateral TMJ internal derangement in a 24-year-old man. Disk repositioning using bone anchors and excision of the ganglion cyst were performed. A unique characteristic of inflammatory infiltrates was revealed in the specimen, and the relationship between these 2 distinct entities and probable pathogenesis of infectious involvement are discussed.

    The cystic appearance of both oesophageal duplications and pulmonary hydatid cysts can cause a misdiagnosis very easily due to rarity of cystic oesophageal duplications beside the higher incidence of hydatid cyst, especially in endemic areas. Here we report a 7-year-old girl with an oesophageal duplication cyst on the left side misdiagnosed as a hydatid cyst. The aim of the study is to report rare oesophageal duplications in the differential diagnosis of intrathoracic cysts. PMID:26702290

    A review of the English literature reveals a total of 1,337 patients with choledochal cysts. Improved diagnostic techniques to visualize the biliary system are demonstrating an increasing number of unsuspected choledochal cysts in adult patients. Either choledochal cysts remain clinically silent until adulthood or may develop in later life. Experience is reported with adult patients having type I, II, III, and IV choledochal cysts. Type I cysts are preferably managed by excision but cyst anatomy may necessitate choledochoenteric drainage. Type II cysts are treated by excision except for those located within the pancreatic portion of the common bile duct. These are best managed by transduodenal cystoduodenostomy. The type III cyst (choledochocele) should be excised carefully, identifying and preserving the common bile and pancreatic ducts. Type IV cysts include a combination of any one of the first three types of cyst plus the presence of intrahepatic cyst or cysts. Treatment of these cysts is dictated by the type and location of the extrahepatic cyst. Since choledochal cysts are being recognized with increased frequency in adults, surgeons need to be aware of the diagnostic and treatment modalities available for each type of biliary cyst.

    2016-01-01

    Background: To evaluate ultrasonographic-guided cyst aspiration and methotrexate injection in the management of simple and endometriotic ovarian cysts in selected patients. Subjects and Methods: This prospective study was conducted in the Department of Obstetrics and Gynaecology in Government Medical College and Hospital, Chandigarh, from November 2007 to October 2009. It included 132 female patients (age range, 15–72 years; mean, 38.7 years) with simple or endometriotic ovarian cysts (3.0–10.6 cm) at ultrasonic examinations. We performed puncture and aspiration followed by methotrexate injection into the cyst. All patients were followed for 12 months. None was lost to follow-up. Results: At follow-up ultrasonography, cysts had disappeared in 120 patients (90.90%) and persisted in 12 patients (9%). No major complications were observed in our study population during or after the procedure. Only 10 patients reported mild pelvic pain, and four others reported dizziness or nausea during or after the procedure. Malignant cells were not found in any of the cases at cytologic examination. We did not observe any cases of infection after the procedure. Conclusion: Ultrasonography-guided transabdominal aspiration of cyst fluid and subsequent methotrexate injection appears to be an alternative treatment for both simple and endometriotic ovarian cysts in selected cases.

    2013-01-01

    Although splenic involvement alone in hydatid disease is very rare, spleen is the third most common organ involved in hydatid disease. The rarity of splenic hydatid disease poses a diagnostic challenge for clinicians, particularly in non-endemic areas. As the hydatid cyst can present as a simple cyst without having the classic serological and imaging features, and later can lead to life-threatening complications like anaphylaxis, hydatid disease of spleen should be considered in differential in every patient in endemic areas with cystic lesion of spleen until proved otherwise. The author used the keyword “splenic hydatid cyst” in PubMed and reviewed the scientific literatures published from January 1965 to June 2012. The present review is to accentuate the incidence, classification, clinical and pathophysiological features, differential diagnosis, diagnostic modalities, and treatment choices of hydatid cyst of spleen along with follow-up strategy and newer treatment approaches.

    A diagnostic radiograph of the posterior regions of the jaws is mandatory if implant placement is considered at these sites. The goal is to avoid damage to important anatomical structures such as the inferior alveolar canal and maxillary sinus. Using radiographs to evaluate the remaining bone height available for implant insertion is a common procedure. Many articles have evaluated the success rates of fixed prostheses supported by osseointegrated implants, indicating high rates of success for prostheses 5-10 years in function. However, if an orthopantomogram machine is not readily available, periapical radiographs can be used for vertical bone height assessment. The familiar procedure of incorporating a metal ball of known diameter into an acrylic template is the method of choice. This is a relatively tedious and expensive procedure involving multiple steps, including impression taking, creation of a study model, and manufacture of a metal ball-bearing acrylic template. A further disadvantage for the patient is that a diagnostic radiograph can be taken only at the next appointment. This paper describes a quick and simple method to obtain a radiographic evaluation of remaining alveolar bone height and soft tissue thickness prior to implant placement with help of a metal ball device to avoid template fabrication and time consumption. Soft tissue thickness is measured nonsurgically. PMID:22313989

    Background/Objective: Tarlov cysts or spinal perineurial cysts are uncommon lesions. These are mostly incidental findings on magnetic resonance imaging or myelograms. The objectives of this study were to describe Tarlov cysts of the sacral region as a potential cause for retrograde ejaculations and review available management options. Methods: Case report and literature review. Results: A 28-year-old man presented with back pain and retrograde ejaculations resulting in infertility. After microsurgical excision of large perineurial cysts, back pain resolved, but semen quality showed only marginal improvement. Later, the couple successfully conceived by intrauterine insemination. To the best of our knowledge, this is the first reported case of Tarlov cyst associated with retrograde ejaculation and infertility. Conclusions: Despite being mostly asymptomatic and an incidental finding, Tarlov cyst is an important clinical entity because of its tendency to increase in size with time. Tarlov cysts of the sacral and cauda equina region may be a rare underlying cause in otherwise unexplained retrograde ejaculations and infertility. Microsurgical excision may be a good option in a select group of patients. PMID:19569467

    INTRODUCTION. Intracranial arachnoids cysts are considered benign developmental anomalies that occur within the arachnoid membrane and generally contain clear and colourless fluid resembling cerebrospinal fluid. The prevalence of these cysts is higher in the first two decades of life, and the incidence is widely quoted as approximately 1% of all space-occupying intracranial lesions. Arachnoids cysts in the elderly person are a rare occurrence. We report the unusual presentation of a woman with an intraventricular arachnoid cyst treated with endoscopic technique. CASE REPORT. A 75-year-old woman presented with progressive hemiparesis of two years duration. Cranial MR imaging showed a right parieto-occipital intraventricular cyst with local mass effect and moderate dilatation of lateral ventricles. A right-sided burr hole was made and the arachnoids cyst was reached and cysto-ventricle shunting was realized. This was followed by a septum pellucidum fenestration. There were no complications during the surgery and the patient presented no symptoms at time of discharge. CONCLUSIONS. The neuroendoscopic approach to intraventricular arachnoid cysts was effective with few complications. PMID:23799598

    Polyacrylamide based tissue mimicking phantom with embedded cysts is designed and analyzed for better understanding of cyst elastograms. Cysts filled with different fluids of varying density and bulk moduli are embedded in the phantom. Characterization is done based on parameters measured from the ultrasound B mode and elastogram of the cystic lesions. Such a phantom can serve as tool for better understanding of the elastographic appearance of cysts. Thus simple and complex cysts can be easily distinguished. It can also be used to teach a complex procedure like ultrasound guided fine needle aspiration. PMID:19163330

    Our experience with 18 patients with simple epidermoid cysts of the testis is reported. In each patient the tumour was enucleated completely and two biopsies of the adjacent parenchyma were obtained for exclusion of associated germ cell cancer, scars or carcinoma in situ. There was no evidence of malignancy in any of the biopsy specimens. Preoperative evaluation included physical examination, testicular sonography, and determination of AFP and hCG serum levels. Although epidermoid cyst can be strongly suspected on sonography the ultrasound appearance is not specific, and inguinal testicular exploration was required in these patients. In 1 patient multiple epidermoid cysts of the right testis were associated with an adult teratoma containing embryonal carcinoma and choriocarcinoma of the left testis; no similar case has been described in the literature. On the basis of our results and experience we consider tumour enucleation and biopsy of the adjacent parenchyma to be adequate treatment for benign epidermoid cyst. The world literature concerning organ-sparing surgery in testicular epidermoid cyst is reviewed. PMID:8851841

    Background and Objectives The epidermoid cyst is a common benign disease of the skin caused by inflammation of hair cortex follicles and proliferation of epidermal cells within the dermis or superficial subcutaneous tissue. The purpose of this study was to investigate the characteristics of epidermoid cysts of the external auditory canal (EAC) by analyzing the clinical and radiologic features. Subjects and Methods The clinical records were retrospectively reviewed for patients diagnosed with epidermoid cyst of the EAC from March 2004 to December 2013. The epidermoid cysts were diagnosed clinically by endoscopy and microscopy examinations and by temporal bone CT images, and were confirmed by histopathologic examination. Characteristics of epidermoid cysts in bony EAC and cartilaginous EAC were compared. Results Eight patients had an epidermoid cyst in the bony EAC and nine patients had one in the cartilaginous EAC. Swelling and otalgia were common symptoms, but 47% of cysts were found incidentally. The mean age of patients was 49.6 years (age range, 26-67 years) in the bony EAC cases and 26.1 years (age range, 6-57 years) in the cartilaginous EAC cases. The mean size of the epidermoid cyst was 3.50 mm (size range, 2-7 mm) in the bony EAC cases and 9.55 mm (size range, 2-20 mm) in the cartilaginous EAC cases. Conclusions Comparison of epidermoid cysts of the bony EAC and the cartilaginous EAC revealed that epidermoid cysts of the bony EAC is usually found incidentally, arose in older patients and had smaller size.

    Purpose: The incidence of painful bone metastases increases with longer survival times. Although external beam radiation therapy (EBRT) is an effective palliative treatment, it often requires several days from the start of treatment to produce a measurable reduction in pain scores and a qualitative amelioration of patient pain levels. Meanwhile, the use of analgesics remains the best approach early on in the treatment course. We investigated the role of radiation therapists as key personnel for collecting daily pain scores to supplement assessments by physician and oncology nursing staff and manage pain more effectively during radiation treatment. Methods and Materials: Daily pain scores were obtained by the radiation therapists for 89 patients undertaking a total of 124 courses of EBRT for bone metastases and compared with pretreatment pain scores. The majority of patients (71%) were treated to 30 Gy (range, 20-37.5) in 10 fractions (range, 8-15 fractions). Results: One hundred nineteen treatment courses (96%) were completed. Pain scores declined rapidly to 37.5%, 50%, and 75% of the pretreatment levels by Days 2, 4, and 10, respectively. Pain was improved in 91% of patients with only 4% of worse pain at the end of treatment. Improved pain scores were maintained in 83% of patients at 1-month follow-up, but in 35% of them, the pain was worse than at the end of treatment. Conclusions: Collection of daily pain scores by radiation therapists was associated with an effective reduction in pain scores early on during EBRT of painful osseous metastases.

    Background: Curettage is one of the most common treatment options for benign lytic bone tumors and tumor like lesions. The resultant defect is usually filled. We report our outcome curettage of benign bone tumors and tumor like lesions without filling the cavity. Materials and Methods: We retrospectively studied 42 patients (28 males and 14 females) with benign bone tumors who had undergone curettage without grafting or filling of the defect by any other bone graft substitute. The age of the patients ranged from 14 to 66 years. The most common histological diagnosis was that of giant cell tumor followed by simple bone cyst, aneurysamal bone cyst, enchondroma, fibrous dysplasia, chondromyxoid fibroma, and chondroblastoma and giant cell reparative granuloma. Of the 15 giant cell tumors, 4 were radiographic grade 1 lesions, 8 were grade 2 and 3 grade 3. The mean maximum diameter of the cysts was 5.1 (range 1.1-9 cm) cm and the mean volume of the lesions was 34.89 cm3 (range 0.94-194.52 cm3). The plain radiographs of the part before and after curettage were reviewed to establish the size of the initial defect and the rate of reconstitution, filling and remodeling of the bone defect. Patients were reviewed every 3 monthly for a minimum period of 2 years. Results: Most of the bone defects completely reconstituted to a normal appearance while the rest filled partially. Two patients had preoperative and three had postoperative fractures. All the fractures healed uneventfully. Local recurrence occurred in three patients with giant cell tumor who were then reoperated. All other patients had unrestricted activities of daily living after surgery. The rate of bone reconstitution, risk of subsequent fracture or the incidence of complications was related to the size of the cyst/tumor at diagnosis. The benign cystic bone lesions with volume greater than approximately 70 cm3 were found to have higher incidence of complications. Conclusion: This study demonstrates the natural

    2014-01-01

    Introduction Intraosseous epidermoid inclusion cysts are rare benign epithelial inclusion cysts in the bone. They are usually found in the cranium and hand phalanges. They are slow growing lesions, and it is difficult to differentiate them from other inflammatory and cystic lesions. Only a few cases of epidermoid inclusion cyst in the jaw have been reported in the literature. This is the fourth case reported as intraosseous epidermoid cyst of the maxilla in the English literature. Case presentation An asymptomatic 59-year-old Caucasian man was referred to our Oral and Maxillofacial Surgery clinic for a unilocular radiolucent area at his anterior maxilla shown on an orthopantomograph. He was scheduled for surgery and underwent cyst extraction surgery. A pathological examination revealed epidermoid cyst. The diagnostic dilemma in this case report in opposition to the presented intraosseous epidermoid cysts in the literature is that there was no trauma history to his upper jaw. Treatment for this cyst is conservative surgical excision and recurrence is uncommon. Conclusions This report presents an unusual case of an intraosseous epidermoid cyst that occurred with no trauma history to the upper jaw. Although only three cases of epidermoid inclusion cyst have been reported in the maxilla, epidermoid inclusion cyst should be considered in the differential diagnosis of radiolucent lesions of the jaws.

    Ganglion cysts have been previously described throughout the body, most commonly about the wrist, hand, knee, ankle, and feet. When symptomatic, they may interfere with joint mechanics, resulting in snapping, catching, and locking. Intratendinous ganglion cysts lack a synovial epithelial lining and are thought to develop from the mucoid degeneration of connective tissue caused by chronic irritation, chronic repetitive injury, and chronic ischemia. On magnetic resonance imaging, ganglion cysts originating from tendons, ligaments, tendon sheaths, menisci, or joint capsules appear as well-defined lobulated masses that follow simple or complex fluid signal intensity on all pulse sequences, with enhancing walls and internal septations on post-contrast images. There may be appreciable degeneration and partial tearing of the structure of origin, particularly if associated with tendons. On ultrasonography, they present as hypoechoic masses, with internal septations and lobulations of varying sizes, without significant vascularity on power or color Doppler sampling. A thin fluid neck extending from the structure of origin (tail sign), when present, is a reliable sign of a ganglion cyst. This article describes a sonographically guided technique to treat symptomatic ganglion cysts within the patellar tendon. Complete evacuation of the ganglion cyst, with disappearance of the tail sign, is considered the determining factor for a successful procedure. A similar technique can be used for the treatment of other symptomatic intratendinous ganglion cysts elsewhere in the body. To our knowledge, symptomatic intratendinous ganglion cysts within the patellar tendon and their treatment have not been previously reported. PMID:21323277

    Epidermoid cyst of the testis is a benign, non-teratomatous tumour. It is often possible to make the diagnosis pre-operatively, combining typical sonographic features with normal biochemical tumour markers. The accurate pre-operative diagnosis will allow for testis-sparing surgery and prevent unnecessary orchiectomy. An 11-year-old boy with testicular epidermoid cyst who presented with pain in testis was presented in this report. PMID:25659561

    Postoperative maxillary cysts are locally aggressive lesions, usually developing as delayed complications many years after radical antral surgery. This report describes a case of bilateral postoperative maxillary cysts following orthognathic surgery performed approximately 21 years previously. The patient complained of stinging pain on her right cheek. Radiographic examination revealed low-attenuation lesions on both maxillary sinuses with discontinuously corticated margins without distinct expansion or bone destruction. The cysts were enucleated with the removal of metal plates and screws for pain relief. Histopathological examination confirmed the diagnosis of postoperative maxillary cysts lined by ciliated, pseudostratified columnar cells. The patient has remained asymptomatic thus far, and there was no evidence of local recurrence at 21 months of postoperative follow-up. PMID:25473641

    Accurate segmentation of abdominal organs from medical images is an essential part of surgical planning and computer-aided disease diagnosis. Many existing algorithms are specialized for the segmentation of healthy organs. Cystic pancreas segmentation is especially challenging due to its low contrast boundaries, variability in shape, location and the stage of the pancreatic cancer. We present a semi-automatic segmentation algorithm for pancreata with cysts. In contrast to existing automatic segmentation approaches for healthy pancreas segmentation which are amenable to atlas/statistical shape approaches, a pancreas with cysts can have even higher variability with respect to the shape of the pancreas due to the size and shape of the cyst(s). Hence, fine results are better attained with semi-automatic steerable approaches. We use a novel combination of random walker and region growing approaches to delineate the boundaries of the pancreas and cysts with respective best Dice coefficients of 85.1% and 86.7%, and respective best volumetric overlap errors of 26.0% and 23.5%. Results show that the proposed algorithm for pancreas and pancreatic cyst segmentation is accurate and stable.

    Study Design This was a retrospective study. Purpose To study the surgical outcome of synovial cysts of the lumbar spine through posterior laminectomy in combination with transpedicular screw fixation. Overview of Literature Synovial cysts of the lumbar spine contribute significantly to narrowing of the spinal canal and lateral thecal sac and nerve root compression. Cysts form as a result of arthrotic disruption of the facet joint, leading to degenerative spondylolisthesis in up to 40% of patients. Methods Retrospective data from 6 patients, treated during the period of March 2007 to February 2011, were analyzed. All preoperative and postoperative manifestations, extension/flexion radiographs, magnetic resonance imaging, and computed tomography records were reviewed. All underwent surgery for synovial cysts with excision and decompression combined with posterior fixation. The result of surgery was evaluated with Macnab's classification. An excellent or good outcome was considered as satisfactory. Japanese Orthopedic Association Scale was used for evaluation of back pain. Results All patients included in this study had excellent outcomes as regarding to improvement of all preoperative manifestations and returning to normal daily activities. Only 2 cases developed postoperative transient cerebro-spinal fluid leak and were treated conservatively and improved during the follow up period. Conclusions Although this study included a small number of cases and we could not have statistically significant results, the good outcome of decompression of synovial cysts combined with posterior fixation and fusion encouraged us to recommend this approach for patients with juxtafacet synovial cysts.

    2010-03-01

    Acromioclavicular joint (ACJ) cysts are an uncommon and unusual sequela associated with shoulder pathophysiology. The majority of literature on ACJ cysts consists of individual case reports with no definitive literature review currently available. In addition to a comprehensive literature review, four clinical cases are presented in this report. First described by Craig (1984), a total of 41 cases have been previously reported in the literature. Of these cases, five occurred with the rotator cuff musculature intact. The remaining 36 cases of ACJ cysts occurred in patients with a complete tear/avulsion of the rotator cuff. Previous attempts at compiling a complete record of all reported cases have combined several distinct conditions into a single category. This article presents two distinct etiologies for the pathogenesis of ACJ cyst formation. In the presence of an intact rotator cuff, a Type 1 cyst can form superficially and be limited to the ACJ. Following a massive or traumatic tear of the rotator cuff, mechanical instability of the humeral head can cause a deterioration of the inferior acromioclavicular capsule (cuff tear arthropathy) and an overproduction of synovial fluid. Overtime, a "geyser" of fluid can form between the glenohumeral and the ACJ, forming a Type 2 cyst. This differentiation and categorization is essential for appropriate classification and treatment.

    The excision of the choledochal cyst with bile drainage through intestinal conduit is a standard operative procedure in the surgical management of choledochal cysts. During the last eight years five patients have been treated with this operation at the University Children's Hospital in Zagreb. All the patients were girls aged from two months to twelve years. The classical triad of pain, jaundice and abdominal mass was observed in only one patient, an eight-year-old girl. The only symptom in infancy was jaundice. Diagnosis was made by abdominal ultrasound, bibliography, CT scan with hepatotropic contrast and in older children by ERCP. Four cysts were type Todani I, and one cyst was Todani type II. The complete excision of the choledochal cyst with the Roux-Y jejunal conduit without antireflux valve was performed. There was neither operative morbidity nor mortality. Three months postoperatively the control ultrasonography and liver laboratory tests were without abnormalities. The routine control which followed did not show episodes of cholangitis, lithiasis, lipid malabsorption, blood clotting abnormalities or growth failure. The complete excision of the cyst with Roux-Y hepaticoenterostomy is an operative treatment with good results in infancy and childhood. PMID:10932533

    As opposed to other odontogenic cysts, the radicular cyst is always produced by intraradicular infection, therefore it is important to eliminate the cause of the inflammation as well. During the healing of the radicular cyst, the infected tooth should be treated by extraction or root canal treatment completed by surgical intervention. The presented case is a 77 year-old male patient with Type II Diabetes, who required oral surgery and endodontic treatment. Despite of the age and diabetes of the patient, the bone regeneration was rapid and complete. Seven months after starting the treatment, the size of the cyst decresed significantly and by 12th month it was perfectly healed. PMID:26731964

    To present 58 cystic space-occupying formations of the spinal canal in 53 cases; these formations are called "juxtafacet cysts". Fifty-Three patients (33 women and 20 men, with an average age of 60.8 years) were evaluated retrospectively by neurosurgery. All of the patients had received simple X-P, computed tomography (CT) and magnetic resonance imaging (MRI) before surgery. The neurological findings were evaluated on admission and in a follow-up review. Surgical intervention was performed on all patients and they underwent gross-total cyst removal. During surgery, the origin of a cyst was well observed. Follow-up data ranged from 6 to 46 months. Patient outcome was graded on a scale of excellent, good, or poor. Histological findings were evaluated. In 53 patients 58 cysts were identified. Four of the patients had multiple cysts. All cysts were associated with mobile spine. Fifty-five cysts were found in the lumbo-sacral region, two cysts were found in the cervico-thoracic region and one cyst in the thoracic region. Forty-two patients presented back pain and 52 patients presented radicular pain. Four patients had a cauda equina syndrome. Sensory disturbance was observed in 24 cases and motor weakness was observed in 21 cases. Claudication was observed in 19 cases. All cases with cervico-thoracic or thoracic cysts presented myelopathy. The duration of these clinical symptoms ranged from 10 days to 10 years. After surgery there was no case of a recurrent cyst during the follow-up period. Thirty-four cases had an excellent outcome, 18 a good outcome, and one a poor outcome. Out of 58 cysts 32 were joint cysts (11 synovial cysts, 21 ganglion cysts). A further 19 were flavum cysts, one was a posterior longitudinal ligament (PLL) cyst and six others were unknown pseudo cysts. In 34 of the cysts we found hemosiderin deposits and in eight amyloid deposits. Present investigation and findings in literature show a clear comparison of these cystic formations and the mobile

A 22-year-old female presented with headache. Cranial MRI showed a left-sided choroidal fissure cyst. Follow-up MRI showed that the size of the cyst had increased gradually. Twenty months later, the patient was admitted to our emergency department with severe headache. MRI and CT showed an intracystic hematoma. Although such cysts usually have a benign course without symptoms and progression, they may rarely present with intracystic hemorrhage, enlargement of the cyst and increasing symptomatology.

    The aim of this study is to show the different diagnostic procedures and treatment in patients diagnosed with congenital choledochal cysts. Choledochal cysts are congenital anomalies of the bile ducts and include cystic dilatation of the extrahepatic and intrahepatic biliary ducts or both. The study shows ten patients diagnosed as having choledochal cysts. Diagnosis was established by clinical and radiographic findings including: ultrasound (US), magnetic resonance cholangiopancreatograpy (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) and cytological examination of the bile juice. In the study choledochal cysts were classified according to the Todani classification. Most common cysts were type I (six cases); type III (one case), type IVa (one case) and two patients were type V cysts (Caroli disease). The most frequent symptoms were abdominal pain, jaundice and cholangitis. US findings were sensitive for the preliminary diagnosis of choledochal cysts in all the patients. MRCP accurately defined the cyst anatomy and the site of the biliary origin in all the cases with extrahepatic cysts. In three cases ERCP clearly demonstrated the cyst and by PTC smaller cysts were well defined. Cytological examination of the bile juice obtained during the PTC procedure showed malignant cells in one case. Therefore pancreaticoduodenectomy was performed and pathological examination showed associated cholangiocarcinoma. Five years after the operation the patient was well and free of the disease. Five patients underwent surgical treatment with a total cyst excision and Roux-en-Y hepaticojejunostomy while the surgical approach in two patients was partial cyst excision and cystojejunostomy. Patients with Caroli disease were conservatively treated and 3 with interventional endoscopic procedures. Despite US evidence suggesting choledochal cyst diagnosis, other supportive radiographic imaging modalities such as MRCP, ERCP and

    With technological advancements and wider availability of multimodality imaging, incidental lesions are frequently identified in patients undergoing various imaging studies. We report here a case of multiloculated disseminated perineural or Tarlov cysts (TCs). The primary aim of our study was to (1) provide a comprehensive review of the clinical, imaging and histopathological features of TCs (2) to draw attention to the fact that multiple lumbo-sacral and dorsal TCs can produce nerve injuries and serious movement disturbances (3) to document the usefulness of the magnetic resonance imaging (MRI) and bone scan in noninvasive diagnosis and guiding management in such cases. These cysts are clearly identified by MR and computerized tomography imaging of the lumbosacral spine. However, there are no reports on the scintigraphic findings of TCs in literature. TCs are typically benign, asymptomatic lesions that can simply be monitored. Until date, no consensus exists about the best surgical strategy to be followed for their management. PMID:25191117

    Introduction: Surgical management of large talar dome cysts is challenging due to increased morbidity by associated cartilage damage and malleolar osteotomy. The purpose of this study is to evaluate the clinical and radiological outcome of endoscopic curettage and bone graft for large talar dome cysts. Methods: This is a retrospective analysis of data for eight patients (eight feet) who were treated by arthroscopic curettage and grafting for large talar dome cysts. Seven cases were treated by posterior ankle arthroscopy as the lesion was located posteriorly while one case was treated by anterior ankle arthroscopy as the lesion was breached anteriorly. Results: The final diagnosis, was; large osteochondral lesion of talus (two cases), aneurysmal bone cyst (ABC) (two case), intra-osseous ganglion (two cases), Chronic infection in talus (one case) and angiomatous lesion of the talus (one case). The mean follow up period was 18.3 (±3.06 SD) months (range 16–25 months). The median preoperative AOFAS score was 74.5 (±5.34 SD) points. The mean postoperative AOFAS score at one year follow up was 94.6 (±2.97 SD) points. None of the patient had recurrence of the lesion during follow up. Return to normal daily activity was achieved at 11.25 (±2.37 SD) weeks. Discussion: In this short case series study, large talar dome bony cysts of different pathologies including aneurysmal bone cysts could be treated effectively by endoscopic curettage and bone grafting with no recurrence no complications during the follow-up period.

    Background In severe chronic stages of emphysema the only treatment is lung transplantation. SO, an urgent need exists for the development of effective treatments. Stem cells therapy arises as a new therapeutic approach. Aim of the Work To investigate whether bone marrow mononuclar cells (BMMNCs) can promote lung regeneration and decrease apoptosis in lipopolysaccharide (LPS) induced pulmonary emphysema in C57Bl/6 mice. Material and Methods 14 weeks old female mice (C57Bl/6), weighing around 25 g were used in this study. The mice were divided into 4 groups (10 in each group): group A: mice received no treatment, group B: mice received intranasal instillation of LPS with no further treatment, group C: mice received intranasal instillation of LPS then given a dose of BMMNCs and evaluated 21 days later and group D: the mice that received intranasal instillation of LPS then given a dose of Dulbecco’s Modified Eagle’s Medium (DMEM) and evaluated 21 days later. Imaging analysis was done using imagej program. To measure apoptotic index, Anti–caspase 3 polyclonal antibody staining was done. Results Analysis of the mean of airspace equivalent diameters (D0) and its statistical distribution (D1) for the different groups allowed to observe that group treated with BMMNCs (group C) showed the significant improvement in D0 and D1 than the group received LPS only (group B). Analysis of apoptotic index showed significant difference between BMMNCs treated group (group C) and that received LPS only (group B). Conclusions BMMNCs effectively promote lung regeneration and reduction of apoptosis in pulmonary emphysema. PMID:27426096

    To highlight the difference in symptoms, clinical features and management of an intralingual thyroglossal cyst from a classical thyroglossal cyst. We present here the case of a 10 year old boy, who presented to us with the chief complaint of difficulty in speech for 2 years. A marble shaped swelling was seen on the base of the tongue. It was diagnosed as an intralingual thyroglossal cyst. He underwent a Sistrunk operation and the cyst was removed from the base of the tongue. Literature search revealed the rarity of this intralingual thyroglossal cyst, its atypical presentation and difference in way of management. A case report and review of literature regarding this unusual unusual entity is presented. An intralingual thyroglossal cyst is the rarest form of a thyroglossal cyst, and differs from a classical thyroglossal cyst totally in presentation and management. PMID:24427642

    Background and purpose The defect that results after curettage of a bone tumor is usually filled in the same way. We report the outcome in patients with benign bone tumors that were treated with curettage but no filling. Patients and methods We retrospectively studied 78 patients (mean age at the time of operation was 27 (6–73) years, 44 men) who had had a benign bone tumor curetted with no filling of the defect. The commonest tumor types were giant cell tumor of bone (27), fibrous dysplasia (13), enchondroma (9), and simple bone cyst (7). The mean size of the lesions was 35 (2–196) cm3. Normal activities, including full weight bearing for lower extremity lesions, were allowed after 3 months or less. The patients were followed for an average of 10 (1.2–21) years. Results A postoperative fracture with a minor displacement occurred in 3 patients, in 2 of them because of local recurrence. All fractures healed. Local recurrence occurred in 9 patients; 7 of them had a giant cell tumor. Repeated local recurrences necessitated above-knee amputation in 1 patient. All other patients had unrestricted activities of daily living. Interpretation Routine filling of curetted bone lesions does not appear to be necessary from a mechanical point of view. PMID:19234882

    In the treatment of the liver hydatid cyst, many surgical techniques have been used, from aspiration, drainage, marsupialization to the complete excision of the cyst with segmentary liver resection. With the appearance of laparoscopic surgery, new chances for the treatment of liver hydatidoses come to us in this frequent pathology in our country. In this paper we show the laparoscopic technique used in some patients seen by us in the last years. After we made the diagnosis, we gave medical treatment with albendazol 400 mg per day during 90 days, prior to surgery. We also used antibiotic prophylaxis with wide spectrum antibiotics. Surgery was performed with the patient in dorsal decubitus with ports: umbilical; 10 mm for angled optics (30-45 ), epigastric;10 mm, for right subcostal in the mid collar bone position. 5 mm for aspiration and forceps and right subcostal and front axillar line. We performed a diagnostic laparoscopy to visualize the cyst. We introduced soaked gauzes with ClNa 21% surrounding the cyst specially in the more protruded zone. Afterwards we punctured the cyst and took laboratory samples searching for the scolex in the direct exam, then we injected ClNa 21% in the cyst. It stay for 5 minutes and we made rechanges for 4-5 times. We take a piece of the wall cyst and adventicy for pathological examination. We take out the germinative layer and the daughter s hydatides with care to put them in extraction bags to leave out their content in a ClNa 21% recipient. Finally we retrieved the gauzes previously introduced, we suck the remaining fluid and introduce a piece of epiplon inside the residual cavity, fixed with suture points to the border and left a 16F fenestrated probe that is left outside by a lateral port. The postoperative management is the same as the laparoscopic colecystectomy. The oral route begins when the postoperative ileum is over (12 to 24 hours), treatment of the pain, prompt deambulation and discharge in relation of the external

    Tibial cyst formation following the use of bioabsorbable interference screws in anterior cruciate ligament (ACL) reconstruction is well-described; however, cyst formation after the use of metallic interference screws is not well-documented. We describe a case of osteolytic lesion of the proximal tibia presenting to us 20 years after ACL reconstruction using an autologous bone-tendon-bone graft. The original graft fixation technique was interference fixation with a metal screw in the tibial and femoral tunnels. A two-stage revision reconstruction of the ACL was undertaken with curettage and bone grafting of the tibial lesion in the first stage and reconstruction using a four-strand hamstring tendon in the second stage. The patient recovered satisfactorily with complete healing of the cyst and returned to pre-injury level of activities. We have reviewed case reports and case series that describe the aetiology of intra-osseous cyst formation following ACL reconstruction. PMID:26673117

    Colloid cysts are a rare clinical finding with a unique clinical presentation: non-specific paroxysmal headaches. The current recommended treatment is microsurgery, which poses the greatest risk to the patient but allows complete removal of the cyst to prevent recurrence. A 41-year old man presented with a colloid cyst located in the foramen of Monro causing obstructive hydrocephalus. He had paroxysmal headaches and memory and personality changes. Transcortical transventricle microsurgery was performed to remove the entire cyst. A temporary shunt was placed to prevent post-operative hydrocephalus. Normal neurological function returned upon cyst removal. PMID:22034805

    Laparoscopic surgery has both diagnostic and therapeutic advantages in the management of intra-abdominal cysts in children. Large cysts in small children pose technical challenges during laparoscopic surgery, requiring multiple incisions and advanced laparoscopic skills. This paper describes a novel laparoscopic technique using minimal manipulation for both aspiration and excision of the cyst. This simple, safe, and effective approach was used to achieve traction and facilitate excision of a large intra-abdominal cyst in a neonate and a young child. PMID:26798349

    Although challenges in treatment of musculoskeletal hydatid cysts (HC) lesions have been documented, data regarding the musculoskeletal HC lesions resembling tumor is scarce. This paper presented 5 patients (3 males, 2 females) with a mean age of 41.6 years with tumor-like lesions of HC. Three of them had left ilium and acetabulum involvement, one involved left femur, and one involved left thigh muscle compartments. Pain was the main symptom and was seen in all patients. Clinical examination, radiologic evaluation, and histologic analysis were performed for diagnosis. Patients were treated through different surgical options, including simple debridement, bone cement filling with or without internal fixation, hip arthrodesis, reconstruction using hemipelvic replantation with femoral prosthesis and distal femur endoprosthetic replacement. After surgery, the operation region was washed by 20% hypertonic saline, and debridement was performed carefully without contamination. All patients received albendazole treatment. Cases were followed up 1 to 9 years for the recurrence. Walking difficulty and pain were the main symptoms during the follow-up. One patient was symptom-free. A reoccurrence in the perioperative soft tissue was detected in only one patient and control visits with antihelmintic treatment were recommended. We would like to emphasize that HC should be kept in mind for the differential diagnosis of the cystic or tumoral lesions of the musculoskeletal system, particularly in the endemic regions. Prompt diagnosis is of paramount importance for preventing destruction and complications. PMID:27384735

    Quantification of Alexandrium cyst fluxes through the Gulf of Maine water column is central to understanding the linkage between the source and fate of annual Alexandrium blooms in the offshore waters. These blooms often lead to paralytic shellfish poisoning (PSP) and extensive closures of shellfish beds. We report here on time-series sediment trap deployments completed at four offshore locations in the gulf between 2005 and 2010 as components of two ECOHAB-GOM field programs. Data presented documents the substantial spatial and temporal fluctuations in Alexandrium fundyense cyst fluxes in the gulf. Cyst delivery out of the euphotic zone peaked primarily between July and August following annual spring-summer Alexandrium blooms and was greatest in the western gulf. At all sites, cyst flux maxima to the subsurface waters were rarely coincident with seasonal peaks in the total mass export of particulate material indicating that cyst delivery was primarily via individually sinking cysts. Where persistent benthic nepheloid layers (BNLs) exist, significant sediment resuspension input of cysts to the near-bottom water column was evidenced by deep cyst fluxes that were up to several orders of magnitude greater than that measured above the BNL. The largest cyst fluxes in the BNL were observed in the eastern gulf, suggesting greater resuspension energy and BNL cyst inventories in this region. Temporal similarities between peak cyst export out of the upper ocean and peak cyst fluxes in the BNL were observed and document the contribution of seasonal, newly formed cysts to the BNL. The data however also suggest that many Alexandrium cells comprising the massive, short-lived blooms do not transition into cysts. Time-series flow measurements and a simple 1D model demonstrate that the BNL cyst fluxes reflect the combined effects of tidal energy-maintained resuspension, deposition, and input of cysts from the overlying water column.

    We present a clinical, neuro-radiological and genetic study on a family with members suffering from an autosomal dominantly inherited syndrome characterised by epilepsy, cerebral calcifications and cysts, bone abnormalities; progressive neuro-cognitive deterioration and paranasal sinusitis. This syndrome shares several features with leukoencephalopathy with calcifications and cysts also called Labrune syndrome and the condition of cerebroretinal microangiopathy with calcifications and cysts (CRMCC; Coats plus syndrome). Genetic studies in this family did not reveal mutations in the CTC1 gene defected in CRMCC. We interpret our results as those supporting recent findings that despite clinical similarities, late-onset Labrune and Coats plus syndrome might be distinct entities. This family may have Labrune syndrome or a yet unclassified entity; exploration of similar cases could help classifying this one, and related conditions. PMID:25034270

    Angiomyolipoma with epithelial cysts is a rare mesenchymal tumor of the kidney that enters in the differential diagnosis of adult cystic renal neoplasms. These tumors demonstrate a slight female predominance and can present either incidentally or with symptoms, commonly flank pain and hematuria. Unlike conventional angiomyolipoma, this variant is characterized grossly by both solid and cystic areas, and histologically by the presence of single or multiple cysts lined by epithelial cells, a subepithelial "cambium-like" layer of small stromal cells with a prominent capillary vasculature, and a thick exterior wall composed of poorly formed fascicles of smooth muscle and thick-walled dysplastic blood vessels. Tumors show a distinct immunohistochemical profile and are often reactive for melanocytic markers (HMB-45 and Melan-A), as well as estrogen receptor and progesterone receptor. These tumors have an indolent clinical course, with no reports of progression or metastasis in reported cases thus far. PMID:27232352

    There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings. PMID:25866380

    We performed an evaluation of ultrasound-guided transvaginal aspiration of ovarian cysts as a viable alternative to surgery in 104 reproductive and 17 postmenopausal women. One-hundred and twenty-one patients with a simple >4 cm diameter ovarian cyst, with a benign appearance on ultrasound as well as on clinical and blood examination, underwent transvaginal fine needle aspiration of the cyst under ultrasonographic control. One-hundred and four patients were of reproductive age and 12 were postmenopausal. Sixty women who were of reproductive age and in which OCP treatment was not contraindicated followed a six-month therapy with oral contraceptives after the intervention. In the group of patients of reproductive age under OCP treatment the cyst persisted in nine of the 60 women (recurrence rate 15%). In the other group of patients of reproductive age,under no OCP treatment, the recurrence rate was 47% (21 of the 44 women). In the group of postmenopausal patients, the cyst persisted in ten out of 17 cases (recurrence rate 58,9%). Transvaginal aspiration of ovarian cysts is a reliable alternative to surgery with many advantages such as excellent tolerance, low risk and cost of complications and recurrence. The OCP treatment after aspiration seems to increase the success rate of expectant management. PMID:21082900

    Background and aims. Pathological fractures are rare in the maxillofacial region and account for less than 2% of all fractures in this site. They are defined as fractures that take place when bone has been weakened by an underlying pathologic process. Among all pathoses, cysts (although so common in the maxillofacial region) constitute a very small part. Here we report a case of a dentigerous cyst in a 38-year-old man.The cyst was associated with a mandibular second premolar tooth and resulted in a pathologic fracture. Excision of the lesion was performed and bony union was observed after 6 months. In the literature review, only one case of dentigerous cyst causing pathologic fracture was found. In addition to the report of the present case, pathologic fractures associated with all types of odontogenic cysts (totally just 12 cases) are reviewed in this article to provide a comprehensive and detailed collection.

    Symptomatic Rathke cleft cysts (RCC) are reported in the sellar and suprasellar regions, but no case of sphenoidal RCC has been reported. We report a case of sphenoidal RCC in a 41-year-old man. The lesion was revealed by headaches and diplopia. Symptoms disappeared transiently after a spontaneous rhinorrhea but relapsed 4 months later. MR imaging showed a cystic sphenoidal lesion, isointense on T1-weighted images (WI) with peripheral gadolinium enhancement and hyperintense on T2 WI. The patient underwent surgery through a transrhinoseptal approach. The wall of the sphenoid sinus was paper-thin. The cyst contained a motor-oil-like fluid and communicated widely with the nasal fossa. Its wall was partially extracted. Symptoms and signs ceased after surgery. MR imaging performed 1 year later showed the disappearance of the sphenoidal cyst. Embryological origin of RCCs is discussed. The hypothesis of a continuum between the different epithelial cystic lesions of the sellar and parasellar region is discussed. Imaging has an important impact on the diagnosis; nevertheless, the specific characterization remains difficult. PMID:16687551

    Five out of 149 patients (3%) who received an intraorbital implant to prevent or treat the disfiguring symptoms associated with the postenucleation socket syndrome developed intraorbital conjunctival cysts. All five patients had received a secondary implant two 14 months previously. After excision of the cysts four patients required additional surgery for lack of conjunctiva and/or recurrent cyst formation. The clinical findings, mechanism of development, and management of this rare but serious complication of socket surgery are described. Images PMID:2043576

    Introduction Osteoarthritic subchondral cysts within or around the hip joint can sometimes be difficult to distinguish from primary osseous and soft tissue tumors due to their radiological appearance and uncommon location. Case presentation We report the case of a 74-year-old Turkish man with a subchondral cyst arising from the hip joint, eroding the acetabulum and located on the medial side of the iliac bone, which imitated a soft tissue tumor. This cystic lesion was resected and the results of histopathological analysis of tissue samples were found to be consistent with an osteoarthritic cyst. Conclusions The present case illustrates how an osteoarthritic subchondral cyst can grow into the soft tissue planes in the presence of destruction of the articular cartilage and subchondral bone continuity, and present as an apparent soft tissue tumor.

    The solid variant of aneurismal bone cysts (ABC) is considered rare. It occurs with greater frequency in pediatric patients and in the tibia, femur, pelvis and humerus. We present a case of a metaphyseal lytic lesion on the distal extremity of the radius in a child whose radiograph was requested after low-energy trauma. The hypothesis of a pathological bone fracture secondary to an aneurysmal bone cyst was suggested. After biopsy, the child underwent intralesional excision without bone grafting and the histopathological findings were compatible with the solid variant of aneurysmal bone cyst. PMID:27274493

    Objectives Quadrigeminal cistern arachnoid cysts (QCACs), which are usually asymptomatic and may be accidental findings during radiological evaluation, are rare, comprising 5-10% of all intracranial arachnoid cysts (ACs). We report a series of eight patients with QCACs treated with neuroendoscopic intervention and try to discuss the different endoscopic approaches according to the different types of QCACs. Materials and methods Between October 2007 and January 2013, eight patients affected by QCACs were endoscopically treated. All the endoscopic procedures were completed uneventfully (infratentorial approaches in four cases and supratentorial approaches in four cases), which included ventriculocystostomy in seven cases (lateral ventriculocystostomy in one case, third ventricle cystostomy in five cases and both in one case), endoscopic third ventriculostomy in three cases and cystocisternostomy in one case. Results Five patients achieved complete cure after the endoscopic procedure alone; nevertheless, in none of the patients did the cyst totally collapse following the endoscopic procedure during follow-up. The number of episodes decreased significantly even after cessation of all medications and headache disappeared in one patient and the two patients who had unsteady gait together with visual complaints showed remarkable improvement. Conclusion QCAC is one kind of pineal region ACs and it is advisable to plan the operative approach before the endoscopic procedure according to the different types of pineal region ACs. Pineal region ACs and the associated hydrocephalus can be successfully treated with simple, minimally invasive endoscopic procedure. PMID:26744082

    Background: The quest for ideal bone graft substitutes still haunts orthopedic researchers. The impetus for this search of newer bone substitutes is provided by mismatch between the demand and supply of autogenous bone grafts. Bone banking facilities such as deep frozen and freeze-dried allografts are not so widely available in most of the developing countries. To overcome the problem, we have used partially decalcified, ethanol preserved, and domestic refrigerator stored allografts which are economical and needs simple technology for procurement, preparation, and preservation. The aim of the study was to assess the radiological and functional outcome of the partially decalcified allograft (by weak hydrochloric acid) in patients of benign lytic lesions of bone. Through this study, we have also tried to evolve, establish, and disseminate the concept of the bone bank. Materials and Methods: 42 cases of lytic lesions of bone who were treated by decalcified (by weak hydrochloric acid), ethanol preserved, allografts were included in this prospective study. The allograft was obtained from freshly amputated limbs or excised femoral heads during hip arthroplasties under strict aseptic conditions. The causes of lytic lesions were unicameral bone cyst (n = 3), aneurysmal bone cyst (n = 3), giant cell tumor (n = 9), fibrous dysplasia (n = 12), chondromyxoid fibroma, chondroma, nonossifying fibroma (n = 1 each), tubercular osteomyelitis (n = 7), and chronic pyogenic osteomyelitis (n = 5). The cavity of the lesion was thoroughly curetted and compactly filled with matchstick sized allografts. Results: Quantitative assessment based on the criteria of Sethi et al. (1993) was done. There was complete assimilation in 27 cases, partial healing in 12 cases, and failure in 3 cases. Functional assessment was also done according to which there were 29 excellent results, 6 good, and 7 cases of failure (infection, recurrence, and nonunion of pathological fracture).

    Neurenteric cysts account for 0.7-1.3% of spinal axis tumors. These rare lesions result from the inappropriate partitioning of the embryonic notochordal plate and presumptive endoderm during the third week of human development. Heterotopic rests of epithelium reminiscent of gastrointestinal and respiratory tissue lead to eventual formation of compressive cystic lesions of the pediatric and adult spine. Histopathological analysis of neurenteric tissue reveals a highly characteristic structure of columnar or cuboidal epithelium with or without cilia and mucus globules. Patients with symptomatic neurenteric cysts typically present in the second and third decades of life with size-dependent myelopathic and/or radicular signs. Magnetic resonance imaging and computed tomography are essential diagnostic tools for the delineation of cyst form and overlying osseous architecture. A variety of approaches have been employed in the treatment of neurenteric cysts each with a goal of total surgical resection. Although long-term outcome analyses are limited, data available indicate that surgical intervention in the case of neurenteric cysts results in a high frequency of resolution of neurological deficit with minimal morbidity. However, recurrence rates as high as 37% have been reported with incomplete resection secondary to factors such as cyst adhesion to surrounding structure and unclear dissection planes. Here we present a systematic review of English language literature from January 1966 to December 2009 utilizing MEDLINE with the following search terminology: neurenteric cyst, enterogenous cyst, spinal cord tumor, spinal dysraphism, intraspinal cyst, intramedullary cyst, and intradural cyst. In addition, the references of publications returned from the MEDLINE search criteria were surveyed in order to examine other pertinent reports. PMID:20890417

    This paper discusses the treatment of impacted permanent incisors and unerupted ectopic canine associated with a dentigerous cyst in mixed dentition that was successfully managed by the combined approach of decompression followed by enucleation, primary closure, autotransplantation and endodontic therapy which enabled the utilization of teeth which were hitherto nonfunctional, transferred to an optimal functional and esthetic position. Decompression is a less invasive technique which reduces the cystic pressure, avoids a more stressful surgical procedure and necessity for general anesthesia. It gives more pleasing results as the body's own mechanism heals the defect gradually. Autotransplantation of teeth induces bone formation around the root with the help of viable periodontal ligament on their root surface. In this case, bone lost by cyst was regenerated and lamina dura was appreciable in the follow up radiographs and transplanted teeth are functioning well. PMID:26225081

  4. Arachnoid cyst slit valves: the mechanism for arachnoid cyst enlargement.

    Arachnoid cysts are common, accounting for approximately 1% of intracranial mass lesions. Most are congenital, clinically silent, and remain static in size. Occasionally, they increase in size and produce symptoms due to mass effect or obstruction. The mechanism of enlargement of arachnoid cysts is controversial. One-way slit valves are often hypothesized as the mechanism for enlargement. The authors present 4 cases of suprasellar prepontine arachnoid cysts in which a slit valve was identified. The patients presented with hydrocephalus due to enlargement of the cyst. The valve was located in the arachnoid wall of the cyst directly over the basilar artery. The authors believe this slit valve was responsible for the net influx of CSF into the cyst and for its enlargement. They also present 1 case of an arachnoid cyst in the middle cranial fossa that had a small circular opening but lacked a slit valve. This cyst did not enlarge but surgery was required because of rupture and the development of a subdural hygroma. One-way slit valves exist and are a possible mechanism of enlargement of suprasellar prepontine arachnoid cysts. The valve was located directly over the basilar artery in each of these cases. Caudad-to-cephalad CSF flow during the cardiac cycle increased the opening of the valve, whereas cephalad-to-caudad CSF flow during the remainder of the cardiac cycle pushed the slit opening against the basilar artery and decreased the size of the opening. Arachnoid cysts that communicate CSF via circular, nonslit valves are probably more likely to remain stable. PMID:23662935

    The objectives of the present study were, first, to establish a methodology for evaluation of the permeability in vitro of hydatid cysts to different drugs and, second, to compare the permeability to albendazole sulfoxide of cysts from untreated animals, cysts from animals treated with 50 mg/kg netobimin for 5 days, and cysts from animals treated with 50 mg/kg netobimin plus 1.1 mg/kg fenbendazole for 5 days. The drug flow follows the Fick law, i.e., the uptake occurs by simple diffusion. We calculated the permeability constant of the cyst membrane by taking into account the disappearance velocity constant, the cyst area, and the incubation solution volume. The permeability value obtained for albendazole sulfoxide was 8.06+/-2.30 x 10(-6) cm s(-1) in cysts from untreated animals, 5.56+/-2.53 x l0(-6) cm s(-1) in cysts from animals treated with netobimin, and 7.05+/-3.04 x 10(-6) cm s(-1) in cysts from animals treated with netobimin +/- fenbendazole. These permeability values show significant differences (P < 0.05). PMID:9610641

    Objective. The aim of this paper is to present an uncommon clinical and radiographic aspect of odontogenic keratocyst (OKC) mimicking paradental cyst. Methods. A 32-year-old female patient showed a well-delimited radiolucent lesion connected with the root of the left third molar with close anatomical relationship with the mandibular canal. The clinical, radiographic, and anamnestic features lead us to diagnose a paradental cyst that was treated by enucleation after extraction of the partially impacted tooth. Results. Histological analysis showed typical histological features of PKC such as the presence of a lining of stratified squamous epithelium with a well-defined basal layer of palisading columnar of cuboidal cells. Conclusion. Initial X-ray analysis and the position of the lesion related to the third mandibular tooth caused us to mistakenly diagnose a paradental cyst. We were only able to identify the cyst as an PKC rather than a paradental cyst after histological analysis. PMID:25114809

    We report an unusual patient with multiple infected cerebral hydatid cysts. A 20-year-old man presented with a 2-month history of headache and progressive left-sided hempiparesis. A cerebral CT scan showed a large and heterogeneous parieto-occipital lesion. During surgery an infected hydatid cyst was discovered with multiple daughter vesicles. Post-operatively the patient was treated with albendazol, cefotaxime and metronidazole. The clinical course was good with total recovery of the hemiparesis. A follow-up CT scan showed persistence of some small deep-seated cysts. Multiple infected cerebral hydatid cyst is uncommon and can be confused with other cystic brain lesions. The aim of surgery is to remove the cyst unruptured and this should be followed by antihelminthic and antibiotic treatment in order to avoid recurrences. PMID:18342511

    Epidermal cysts also known as epidermoid cysts, is one of the common benign tumours presenting anywhere in the body. However, epidermal cyst in the penis is very rare. This condition in children is usually congenital due to abnormal embryologic closure of the median raphe; hence, it is termed as median raphe cysts (MRCs). Penile epidermal cysts may occur in adults following trauma or surgery due to epidermal elements being trapped within closed space. During wound healing, trapped squamous epithelium, undergoing keratinisation leads to cyst formation.

    In Western Siberia (Russia) there are about 100 Artemia lakes with total area over 1 600 km2. Geographically these lakes are located between 51°-56°N and 61°-82°E. In general these lakes are shallow (depth less than 1.5 m), small or medium size (0.1 to 10 km2); they are chloride; their total salinity is from 40 to 250 g/L. The harvesting of cysts per year is only in 20-40 lakes. In Russia 550 tons of dry Artemia cysts (14%-18% of the world production) were harvested annually. This includes about 350 tons in the Altai region and 200 tons in other regions. During our regular 20-year study period the cyst harvest was: 95 tons in Kurgan; 65 tons in Omsk, 20 tons in Novosibirsk, 20 tons in Tyumen. Ways of increasing cyst harvest in Russia are considered in this article. During the last 30 years the harvest of cysts in Russia has increased from 7-20 to 500-600 tons. A significant influence of dryness of the year was found on productivity in selected lakes, but taken for all the lakes together, the relationship was not significant. The optimal salinity for productivity of cysts in the lakes was determined. Analysis of productivity of the lakes and the harvesting results showed that the stocks of cysts are underutilized by approximately 1.7 times.

  15. Spinal perineurial and meningeal cysts.

    PubMed

    Tarlov, I M

    1970-12-01

    Perineurial cysts may be responsible for clinical symptoms and a cure effected by their removal. They do not fill on initial myelography but may fill with Pantopaque some time, days or weeks, after Pantopaque has been instilled into the subarachnoid space. Perineurial cysts arise at the site of the posterior root ganglion. The cyst wall is composed of neural tissue. When initial myelography fails to reveal an adequate cause for the patient's symptoms and signs referable to the caudal nerve roots, then about a millilitre of Pantopaque should be left in the canal for delayed myelography which may later reveal a sacral perineurial cyst or, occasionally, a meningeal cyst. Meningeal diverticula occur proximal to the posterior root ganglia and usually fill on initial myelography. They are in free communication with the subarachnoid space and are rarely in my experience responsible for clinical symptoms. Meningeal diverticula and meningeal cysts appear to represent a continuum. Pantopaque left in the subarachnoid space may convert a meningeal diverticulum into an expanding symptomatic meningeal cyst, as in the case described. Many cases described as perineurial cysts represent abnormally long arachnoidal prolongations over nerve roots or meningeal diverticula. In general, neither of the latter is of pathological significance. Perineurial, like meningeal cysts and diverticula, may be asymptomatic. They should be operated upon only if they produce progressive or disabling symptoms or signs clearly attributable to them. When myelography must be done, and this should be done only as a preliminary to a probable necessary operation, then patient effort should be made to remove the Pantopaque. PMID:5531903

Through the years there have been numerous reports on this subject, but no consensus has been reached with regard to chromosomal risk. In this review, we attempt to summarise published reports on second trimester choroid plexus cysts, with an emphasis on the strengths and weaknesses of each report. Based on these reports, additional malformations are a significant risk factor for aneuploidy and an indication for determination of fetal karyotype. The management of isolated choroid plexus cysts remains controversial. PMID:9678699

    Cystic hydatid disease is an endemic disease caused by the larval form of Echinococcus spp. Isolated renal involvement is extremely rare. The treatment methods for renal hydatid disease require some form of intervention, ranging from traditional open techniques to laparoscopic techniques. Herein, we present a large hydatid cyst in the lower pole of the left kidney in a 43-year-old male patient who was treated by the "closed cyst" method via the retroperitoneal laparoscopic approach to prevent soiling of the peritoneal cavity. To our knowledge, this is the first case of a renal hydatid cyst treated by preserving the renal parenchyma by pericystectomy via the retroperitoneoscopic laparoscopic approach in an adult patient. No complications occurred during the perioperative and postoperative periods. After 9 months of follow up, the patient was asymptomatic with no evidence of clinical recurrence. Retroperitoneoscopic laparoscopic closed cyst pericystectomy can be an alternative minimally invasive treatment technique for the treatment of renal hydatid disease. PMID:21226768

    Advances in genomics, bioinformatics and the creation of model organisms have identified many genes associated with polycystic kidney diseases. Historically, these genes were not necessarily associated with ciliopathies, but it appeared that many connections can be made between the cystic kidney disease and function of the primary cilium. Indeed, the proteins encoded by these genes are localized to the cilium itself, to the basal body or are known to regulate the expression and localization of ciliary proteins. The goal of this article is to describe the multiple cellular processes that may lead to the development of renal cysts if they are deregulated. These include changes in proliferation rate, cell polarity or signaling pathways involved in embryonic kidney development. To highlight the role of the primary cilium in cystogenesis, I will discuss several studies investigating the function of ciliary genes and cilia in the kidneys of different model organisms.

    Background: Liver cysts have been estimated to occur in 5% of the population. Multiple liver cysts can also be part of the polycystic disease complex. Only symptomatic or complicated cysts need surgery. Traditionally, laparotomy is the procedure of choice. We present our experiences with laparoscopic management of both symptomatic multiple liver cysts and polycystic liver disease. Methods: Between 1995 and 2006, we treated 12 patients with large, multiple liver cysts, including 4 cases of polycystic liver disease. Most of the patients were elderly males. The lung and other organs were not involved in any case. Laparoscopic deroofing or radical excision with omentoplasty was successfully performed in these patients. Results: Postoperatively, 4 patients had fluid draining through the drainage tube for an average of 10 days. One patient had ascites that resolved spontaneously. Cysts recurred in 5 patients. Discussion: There are not many reports in the literature regarding large series of patients, further confirming the rarity of the disease. Liver cysts can occur as a part of polycystic renal and lung disease or isolated to the liver alone. Laparoscopic deroofing is the ideal treatment for nonpolycystic liver disease, and laparoscopic radical excision is ideal for polycystic liver disease. Simple needle aspiration or sclerotherapy is inadequate as recurrence is almost 100%. Conclusion: Currently, laparoscopy scores over laparotomy for the treatment of nonparasitic liver cysts as evidenced by this and other studies. PMID:18237512

    Orbitofacial dermoid cysts in children are treated using surgical excision. Dermoid cysts of the frontotemporal region usually present as superficial, slow-growing masses without deep extension. We report a rare case wherein a frontotemporal dermoid in a 21-month-old girl presented with a draining sinus tract to the skin and extended intracranially through the sphenoid bone. It was removed surgically and a dermoid cyst was removed from the frontotemporal region, extending superficially from the skin sinus tract through the sphenoid bone and attaching to the dura of the anterior temporal lobe. In addition to our case presentation, a literature review was performed to identify the few reported similar cases in the published literature, the combination of which suggests that frontotemporal dermoid cysts with associated draining sinus tracts may require preoperative imaging with computed tomography or magnetic resonance imaging before surgical intervention because of the high likelihood of intracranial extension.

    Background: To discuss the experience of diagnosis and treatment of ovarian cyst in infants. Materials and Methods: A retrospective review was conducted on 20 infants who suffered from ovarian cyst. Results: There were no dysplasia ovarian was found in children which were preoperatively diagnosed simplex cyst. Within thirteen children preoperatively detected mixed cystic-solid lesion, six cases ovarian cysts disappeared and two cases underwent poor blood supply in the following time. Conclusion: Adverse effects for ovarian cyst in infants can be prevented by agressive surgical intervention. Harmful effects of ovarian cyst can be prevented by positive surgical intervention despite the diagnostic difficulties in children with clinical symptoms of this condition. PMID:26958055

    Neurenteric cysts in the central nervous system are rare developmental malformations. Usually the cysts are located ventral to the high thoracic or low cervical spinal cord. Only a few cases of intracranial neurenteric cysts have been reported in the literature to date. We report two cases of intracranial neurenteric cysts in the cerebellopontine angle with totally different radiographic, macroscopic, and microscopic appearance. As seen in these cases, the imaging spectrum of neurenteric cysts can be diverse, including malignancy-suspecting partial rim-enhancement or low-grade glioma features. Microsurgical therapy should include endoscopic assistance to ensure complete removal of cyst content. PMID:23397125

    The aneurysmal bone cyst (ABC) is a benign tumour of children and young adults. It represents approximately 1-2% of all bone tumours. The ABC may develop on all skeletal bones, but the proximal end of the femur is the most common location. The authors report a ABC femoral neck in a child of 13 years. This location is pretty special. Indeed, the fragility of the femoral neck due partly to the pathology itself and secondarily curettage requires a judicious attitude surgical (excisional curettage + bone graft + screw) to prevent the risk of high local recurrence and pathological fracture.

    Pycnodysostosis is a rare autosomal recessive disorder caused by mutations in the cysteine protease Cathepsin K gene located on chromosome 1q21. It has a well characterized skeletal phenotype which include short stature, generalized increased bone density with propensity of fractures, open calvarial sutures and fontanelle, dental abnormalities, obtuse mandibular angle, resorption of lateral end of clavicle, acro-osteolysis, and in some cases visceromegaly. Central nervous system involvement is very rare and porencephalic cysts has been reported only once, the cause being hypothesised to be an imbalance between the growing brain, its vascular supply and intraventricular fluid pressure. We had a patient with bilateral frontal lobe porencephalic cysts; the patient presenting with complex partial seizures. Cathepsins have been found to be involved in neurological diseases and role of proteases has been well established in gliosis. PMID:25002775

    With technological advancements and wider availability of multimodality imaging, incidental lesions are frequently identified in patients undergoing various imaging studies. We report here a case of multiloculated disseminated perineural or Tarlov cysts (TCs). The primary aim of this case study was to (1) provide a comprehensive review of the clinical, imaging, and histopathological features of TCs (2) to draw attention to the fact that multiple lumbosacral and dorsal TCs can produce nerve injuries and serious movement disturbances, and (3) to document the usefulness of the magnetic resonance imaging and bone scan in non-invasive diagnosis and guiding management in such cases. These cysts are clearly identified by magnetic resonance imaging (MRI) and computerized tomography imaging of the lumbosacral spine. However, there are no reports on the scintigraphic findings of multilocular disseminated TC in literature. TCs are typically benign, asymptomatic lesions that can simply be monitored. To date, no consensus exists about the best surgical strategy to use when indicated. PMID:23723584

    Background: Management of popliteal cyst is controversial. Owing to high failure rates in open procedures, recent trend is towards arthroscopic decompression and simultaneous management of intraarticular pathology. We retrospectively analysed clinical results of symptomatic popliteal cysts after arthroscopic management at 24 month followup. Materials and Methods: Retrospective analysis of hospital database for patients presenting with pathology suggestive of a popliteal cyst from June 2007 to December 2012 was done. Twelve cases of popliteal cyst not responding to NSAIDS and with Rauschning and Lindgren Grade 2 or 3 who consented for surgical intervention were included in the study. All patients underwent arthroscopic decompression using a posteromedial portal along with management of intraarticular pathologies as encountered. Furthermore, the unidirectional valvular effect was corrected to a bidirectional one by widening the cyst joint interface. The results were assessed as per the Rauschning and Lindgren criteria. Results: All patients were followed for a minimum of 24 months (range 24-36 months). It revealed that among the study group, six patients achieved Grade 0 status while five had a minimal limitation of range of motion accompanied by occasional pain (Grade 1). One patient had a failure of treatment with no change in the clinical grading. Conclusion: Arthroscopic approach gives easy access to decompression with the simultaneous management of articular pathologies. PMID:27053804

    To describe post-traumatic and congenital respiratory epithelial cysts in the orbit, which are rare lesions with only 5 and 13 published cases, respectively. We reviewed all cases of respiratory epithelial cysts diagnosed at three institutions (two tertiary referral hospitals, one private clinic) between 1995 and 2015. We describe 10 cases of post-traumatic respiratory epithelial cyst (age range 23 - 82), presenting a mean of 17.4 years after their original trauma; and 3 congenital cases (age range 17-34). All but one case underwent surgical excision of the cyst and its lining, along with any surgical implant within the cyst. Two were recurrent after incomplete excision. Three presented with acute infection within the cyst. Respiratory epithelial orbital cysts are probably commoner than the paucity of published reports would suggest. Post-traumatic cysts often present many years after trauma, and may become secondarily infected. Complete surgical removal is recommended to prevent future recurrence. PMID:27468088

    Perineural cysts have become a common incidental finding during lumbosacral magnetic resonance (MR) imaging. Only some of the symptomatic cysts warrant treatment. The authors describe the successful operative treatment of a patient with, to the best of their knowledge, the largest perineural cyst reported to date. A 29-year-old woman had been suffering from long-standing constipation and low-back pain. During an obstetric investigation for infertility, the clinician discovered a huge presacral cystic mass. Computed tomography myelography showed the lesion to be a huge Tarlov cyst arising from the left S-3 nerve root and compressing the ipsilateral S-2 nerve. The cyst was successfully treated by ligation of the cyst neck together with sectioning of the S-3 nerve root. Postoperative improvement in her symptoms and MR imaging findings were noted. Identification of the nerve root involved by the cyst wall, operative indication, operative procedure, and treatment of multiple cysts are important preoperative considerations. PMID:17688070

    We review 12 cases of ganglion cyst with carpal tunnel syndrome in 11 patients seen at the Hand Rehabilitation Center. Mean age was 42 years (range, 28 to 60 years). One half of the cysts were associated with direct trauma, usually with wrist hyperextension. Symptoms usually developed after the appearance or sudden growth of the cyst. Motor conduction or distal sensory latency was abnormal in seven of eight studied cases. Tinel's sign on tapping the cyst may be pathognomonic for this syndrome. Cyst removal and incision of the flexor retinaculum relieved the symptoms in 11 cases. The other case had total resolution after spontaneous cyst rupture. This syndrome is successfully treated with cyst decompression with release of the carpal canal and has an excellent prognosis. To our knowledge this represents the largest operative series of carpal tunnel syndrome and ganglion cyst. PMID:3241055

    Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus, E.multilocularis or E.Vogli. The most common primary site is liver (75%) followed by lungs (5-15%) and other organs constitute 10-20%. Peritoneal hydatid cysts are very rare especially primary peritoneal hydatid. Secondary peritoneal hydatid cysts are relatively common, which usually occurs due to rupture of primary hepatic hydatid cyst. We present a rare case of large primary peritoneal hydatid cyst misdiagnosed as torsion of ovarian cyst that underwent Laparotomy with cyst excision and postoperative Albendazole therapy.

    Accurate diagnosis and management of knee pain with or without mechanical symptoms challenges the physical therapist's clinical reasoning skills. Meniscal cysts are one relatively rare disorder of the knee that can cause both pain and mechanical symptoms and are frequently associated with a meniscal tear. In patients with suspected meniscal cysts, systematic differential diagnosis and sound clinical reasoning encourages appropriate integration of the clinical examination with diagnostic imaging. These case reports describe two different presentations of lateral parameniscal cysts where integration of the clinical examination with appropriate imaging allowed the physical therapist to provide a timely and appropriate intervention. In both cases, the diagnostic process is described along with the subsequent interventions that lead to positive outcomes. Level of Evidence: 5 (Case Report) PMID:23772349

    Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5.2 cm x 3.8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case. PMID:18008017

    A 56-year-old man presented himself for an intracranial glioblastoma multiforme excision. After being routinely monitored, he was preoxygenated. We induced anesthesia and paralysis with 200 mg propofol, 50 μg fentanyl and 9 mg vecuronium. Direct laryngoscopy with a Macintosh 3 blade revealed a 2x2 cm cyst, pedunculated, arising from the right side of the vallecula preventing the endotracheal intubation. While the patient remained anesthetized, we urgently consulted an otolaryngologist and aspirated the cyst with a 22-gauge needle and syringe under direct laryngoscopy. We aspirated 10 cc of liquid content. This was followed by an uneventful tracheal intubation with a 9.0 enforced spiral cuffed tube. An alternative to fiberoptic intubation may be careful cyst aspiration to facilitate the intubation. PMID:24263047

    Cystic hydatid disease is a zoonosis caused by infection with the larval cysts of Echinococcus granulosus. Cysts commonly develop in the liver and lungs. Diagnosis in non-endemic regions is often delayed due to a failure to consider hydatidosis. This results from a non-specific presentation and a failure to record an accurate geographical history. The diagnosis requires integrating an appropriate index of suspicion with correct interpretation of imaging and serological tests. In our case, a 44-year-old woman of Yemeni origin presented to a UK hospital with chest pain, pruritus and weight loss. Following detection of pulmonary nodules, a CT-guided biopsy was carried out to exclude malignancy. Iatrogenic cyst rupture precipitated an acute eosinophilic pleurisy. Cystic hydatid disease was subsequently diagnosed following strongly positive hydatid serological tests. This case illustrates the importance of considering diagnoses appropriate to an individual's geographical history particularly in the context of rising immigration and foreign travel. PMID:22778194

    The paradental cyst is commonly misinterpreted when associated with atypical clinical and radiographic characteristics, in turn causing diagnostic problems. For this reason, the study of the differential diagnosis of this lesion has become extremely important. In addition, the correlation of clinical, histologic, and radiographic findings are also of great value in obtaining accurate diagnoses. The minor variations in the clinical appearance of paradental cysts make it feasible to consider the two main groups of cysts separately: those associated with 1st and 2nd permanent molars of the mandible and those associated with the 3rd mandibular molar. Moreover, this distinction in localization may well dictate the necessary treatment. Bearing in mind the minor clinical variations, the present article aims to discuss the differential diagnosis of this lesion and its different possible treatments by presenting a case report to illustrate the findings.

    Symptomatic lumbar synovial cysts (LSCs) are a rare cause of degenerative narrowing of the spinal canal, with thecal sac or nerve root compression. True synovial cysts have a thick wall lined by synovial cells, containing granulation tissue, numerous histiocytes, and giant cells. In contrast, pseudo-cysts lack specialized epithelium, have a collagenous capsule filled with myxoid material, and may be classified into ganglion cysts, originating from periarticular fibrous tissues, and ligamentous cysts, arising from the ligamentum flavum or even from the posterior longitudinal ligament. Here we present the surgical series of the Chair of Neurosurgery at the University of Cagliari (Italy) including a total of 17 LSCs. Surgical technique consisted of facet sparing excision of LSC, achieved by simple hemilaminectomy/laminectomy, and diagnosis was always confirmed by histological specimen examination, which detected the typical synovial epithelium, the intracystic presence of hemosiderin, histiocytes, and calcifications. Further immunohistochemical investigation revealed positive staining for cytokeratin: CK5, CK6, and AE1/AE3. Clinically, our cohort experienced rapid and complete resolution of symptoms, without perioperative complications, or recurrence of cysts or vertebral instability at a median follow up of 28 months, when the MacNab score was generally excellent. A review of the literature, retrieving articles published from 1973, collected a total of 101 articles concerning all the cases of LSC scientifically described to date. Both clinical and histological findings described in our study support the theory of degenerative microtraumatic pathogenesis of synovial cysts. PMID:23438660

We report a 42-year-old male who presented to our hospital with diarrhea and weight loss of six months' duration. Ultrasonography of the abdomen revealed bilateral polycystic kidneys with multiple cystic and solid components as well as polycystic pancreas. A computerized tomography scan of the abdomen revealed bilateral multiple simple and complex renal cysts, cystic lesions in the head and body of the pancreas and a non-enhancing lesion in the left adrenal gland. The features raised the possibility of VHL syndrome and a biopsy of the kidney revealed atypical cells with a suspicion of malignancy. He underwent bilateral nephrectomy and is on maintenance dialysis since then. PMID:24434396

    The aims of this article are to present a case demonstrating the connection between palatoradicular grooves and inflammatory collateral cysts and to discuss the related nomenclature. Radiographs in a 21-year-old man revealed a radiolucent, unilocular, well-defined area near the vital maxillary right lateral incisor and canine. Palatal swelling was present, and a 6-mm-deep periodontal pocket was found at the palatal surface of the right lateral incisor. The differential diagnoses were keratocystic odontogenic tumor, developmental lateral periodontal cyst, and inflammatory lateral periodontal cyst. The area was explored surgically, and the lesion was excised. Surgical exploration revealed a palatoradicular groove, which was scaled and planed with the aid of manual curettes with the intention of creating a flat surface to promote insertion of the periodontal fibers. Histopathologic analysis revealed that the lesion was an inflammatory cyst. The presence of a palatoradicular groove can put the periodontium at risk because a resulting lack of fiber insertion makes oral hygiene difficult. This established inflammatory process can initiate development of an inflammatory collateral cyst that may be misdiagnosed, hindering successful management. In this case, bone grafting and placement of a resorbable membrane were used to promote bone formation and subsequent sealing of the periodontal space. PMID:27148666

    Fifty-five patients, (30 Rheumatoid Arthritis (RA) and 25 Osteoarthritis (OA], with knee synovial effusion and popliteal cysts, visualized through arthrograms, were studied. A relationship was sought between radiological findings and area of the cysts, measured through a millimeter grid. Ten radiological parameters were graded and summed up to obtain a "total knee score". A "total geode score" was also obtained by scoring, separately, the geodes. In addition two specific indexes were used--for comparison--the erosive index, modified after Berens and Lin, in RA and the Kelligren's index in OA. In RA a statistically significant, inverse correlation was found between the x-ray scores and the area of the cysts, while such a relationship was not observed in OA. However, only a third of the cysts accounted for the inverse relationship in RA. Furthermore, two control groups of RA and OA patients revealed a striking association between degree of radiological damage and frequency of popliteal cysts. Therefore, the hypothesis that popliteal cysts might have a protective effect against the articular-bone damage in RA, can be held only in few cases. PMID:3594963

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst. PMID:22787551

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst. PMID:22787551

    Paraurethral cysts arising from Skene's gland are a rare cause of urogenital masses in the neonate. We report the case of a pelvic mass noted at the vaginal introitus on prenatal ultrasound that following delivery was found to be a paraurethral cyst. On prenatal ultrasound, there was no evidence of involvement of the urinary, gastrointestinal, or upper genital tract. Serial ultrasounds demonstrated slight enlargement of the cyst without other changes. The patient delivered at 33 weeks and postnatal evaluation demonstrated a paraurethral cyst. The cyst was managed expectantly and drained spontaneously on the second day of life with complete resolution. PMID:23146295

    Ganglion cysts are considered the most common tumor of the wrist and hand. They are most common between the second and fourth decades of life. The most common anatomical location is the dorsal wrist. This article includes a general review of these cysts including symptoms, pathology and methods of diagnosis, as well as a review of these cysts in specific anatomic locations. The article also includes an updated review of the literature comparing open surgery vs. arthroscopic treatment. The authors believe that arthroscopic surgery of ganglion cysts will gain an important role in the treatment of these cysts. PMID:24450035

    More precise methods are needed to recover Giardia and Cryptosporidium (oo)cysts from wastewater in order to advance research related to their inactivation, removal, quantification, and species differentiation. This study applied different methods to recover the maximum number of (oo)cysts from wastewater samples using ColorSeed®. Immunomagnetic separation assisted in capturing oocysts mainly in samples with medium and low turbidity. A triple centrifugation method reached recovery rates of 85% and 20%, for Giardia cysts and Cryptosporidium oocysts, respectively, in raw wastewater, and 62.5 and 17.5% in secondary-treated effluent. For low turbidity-treated effluent, membrane filtration reached 67.5% recovery for Giardia cysts and 22.5% for Cryptosporidium oocysts. Simple, quick and low-cost methods do not involve much handling of the samples and could be useful, particularly in developing countries. PMID:26322766

    Paralabral cyst of the shoulder joint can be observed in 2% to 4% of the general population, particularly in men during the third and fourth decade. On average, these cysts measure 10 mm to 20 mm in diameter and are located preferentially on the postero-superior aspect of the glenoid. The MRI has increased the frequency of the diagnosis of paralabral cysts of the shoulder joint. Paralabral cysts of the shoulder joint usually develop in the proximity of the labrum. The relationship between shoulder instability and labral tears is well known, however, the association of shoulder instability with a paralabral cyst is rare. Shoulder instability may cause labral injury or labral injury may cause shoulder instability, and then injured tear develops paralabral cyst. In our patient, the inferior paralabral cyst may be associated with inferior labral tears and instability MRI. PMID:20514270

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion. The cysts are relatively rare and most of them are asymptomatic. Some Tarlov cysts can exert pressure on nerve elements resulting in pain, radiculopathy and even multiple radiculopathy of cauda equina. There is no consensus on the appropriate therapeutic options of Tarlov cysts. The authors present a case of two sacral cysts diagnosed with magnetic resonance imaging. The initial symptoms were low back pain and sciatica and progressed to cauda equina syndrome. Surgical treatment was performed by sacral laminectomy and wide cyst fenestration. The neurological deficits were recovered and had not recurred after a follow-up period of nine months. The literature was reviewed and discussed. This is the first reported case in Thailand.

    Reinke edema is one of the common cause of dysphonia middle-aged population, and severe thickening of vocal folds require surgical treatment. Smoking plays a major role on etiology. Vocal fold cysts are also benign lesions and vocal trauma blamed for acquired cysts. We would like to present 3 cases with vocal fold cyst related with Reinke edema. First case had a subepidermal epidermoid cyst with Reinke edema, which could be easily observed before surgery during laryngostroboscopy. Second case had a mucous retention cyst into the edematous Reinke tissue, which was detected during surgical intervention, and third case had a epidermoid cyst that occurred 2 months after before microlaryngeal operation regarding Reinke edema reduction. These 3 cases revealed that surgical management of Reinke edema needs a careful dissection and close follow-up after surgery for presence of vocal fold cysts. PMID:26080256

    Ganglion cysts were diagnosed in a 4-month-old male Afghan Hound. Grossly, the subcutaneous ovoid cysts around the caudal right elbow joint and left ischiatic tuberosity had abundant mucinous fluid and internal folding. The lesions recurred twice around the elbow joint after surgical removal. Neither cyst communicated with the joint cavity. Histologically, the cyst wall consisted of inner myxomatous and outer immature connective tissue. Some parts of the cyst wall had various stages of myxoid metaplasia of collagen tissue leading to new cyst formation. Ultrastructural study revealed that cells in the myxoid metaplastic lesion had well-developed cytoplasmic secretory elements, including abundant rough endoplasmic reticulum, Golgi apparatus, and many smooth-walled vesicles. These ganglion cysts apparently resulted from the metaplasia of fibroblasts to secreting cells. PMID:10896396

    2014-01-01

    Introduction: Scalloping sacral arachnoid cyst though a rare condition, should be suspected in cases of persistent perianal pain without any obvious urological or anorectal pathology. Such difficult cases justify ordering an M.R.I of spine as plain X-Rays and clinical examination may come out to be inconclusive. X-ray in later stages may show changes corresponding to scalloping of bone due pressure effect of cyst on surrounding tissue. Diagnosis may further be confirmed by doing contrast MRI which differentiates arachnoid cyst from other intradural and extradural pathologies. Though anatomically spinal arachnoid cysts are just an out pouching from the spinal meningeal sac or nerve root sheath they may be extradural or intradural in their location, communicating to main C.S.F column through their pedicle or an ostium leading to continuous enlargement in size. Case Report: A 32 year old female was admitted under our spine unit with 1.5 year history of chronic pain, swelling and reduced sensation in perianal region. On examination she had tenderness and hypoesthesia over lower sacral region. The pain was continuous, dull aching in nature, not related to activity, localized over lower sacrum and perianal area. The neurological examination of her both lower limbs were unremarkable. Anal tone and anal reflex were normal. No sign of inflammation or tenderness was found over coccyx. Since the X-rays were inconclusive an MRI scan was done which showed a cystic lesion in the sacral area extending from S2 to S4 region with mechanical scalloping effect on the surrounding bone. The lesion had same intensity as C.S.F in both T1 &T2 weighted images. The treatment was done by way of surgical decompression with complete excision of cyst and obliteration of space by a posterior midline approach. Presently the patient is 1 year post operative and no sign of recurrence is there. Conclusion: Sacral arachnoid cysts should be considered as a differential diagnosis of perianal pain. Large

    Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used. PMID:26730005

    Disturbances of the dental development may result in anomalies, which may be apparent as soon as the child is born. Eruption cysts are rarely observed in neonates considering that at this stage of the child's life teeth eruption is uncommon. Thus, the aim of this report is to describe a case of eruption cysts in a neonate. A male neonate was brought to the emergency service with the chief complaint of an elevated area on the anterior region of the inferior alveolar ridge. The lesion was clinically characterized as a compressive and floating swelling. Through a radiographic exam two mandibular primary incisors could be seen superficially located. Due to the patient's age and the initial diagnosis of eruption cysts the conduct adopted was clinical surveillance. Forty-five days after the first visit the lesions had significantly decreased in size, and completely disappeared after 4 months. At that age, both mandibular central incisors were already in the oral cavity exhibiting small hypoplastic areas in the incisal edges. The clinical and radiographic follow-up of eruption cysts in neonates appears to be an adequate conduct without differing from that recommended for older children. PMID:18524277

    The hydatid disease caused by Echinococcus granulosus is an endemic parasitic disease affecting several Mediterranean countries. Echinococcal cysts are mostly located in the liver and the lung, but the disease can be detected anywhere in the body. In this study, we present uncommon extrahepatic localizations of primary hydatid disease. Patients who were operated on for hydatid disease or cystic lesions, which were later diagnosed as hydatid disease, between 2004 and 2010 were retrieved retrospectively. Patients with lesions localized outside the liver and the lung were enrolled in the study. Eight patients with extrahepatic primary hydatid disease were treated surgically at our clinic. The cysts were located in the scapular region, spleen, pancreas, lumbosacral region and gluteal muscle. Surgical techniques were partial or total cystectomy with or without tube drainage. Splenectomy was performed for splenic hydatid disease and partial pericystectomy, Roux-en-Y cystojejunostomy, cholecystectomy and T-tube drainage for pancreatic hydatid disease. There were no complications or mortality in the postoperative period. Hydatid cyst should be considered in the differential diagnosis of cystic lesions, especially in endemic areas. Surgical technique should be planned according to the location of the cyst. PMID:27436938

    Hydatid cyst (HC) is an endemic infestation in the cattle-breading countries such as in Iran. The involvement of heart by HC is rare; however, nesting of larva in the left ventricular apex with subsequent rupture to the systemic circulation and thrombus formation in the remaining cyst cavity is an exceedingly rare phenomenon. A 45-year-old man referred to our emergency cardiac room with chest pain and a transthoracic echocardiography (TTE) that showed a cardiac apex cystic lesion. The differential diagnosis of a cystic tumor, a HC, or aneurysm in the apex of the left ventricular walls was considered and evaluated by TTE and magnetic resonance imaging. However, the thrombotic HC was confirmed at the surgery. The cyst with its thrombotic component was excised surgically by on-pump cardiac surgery. The postoperative period was uneventful and the patient was discharged to home and treated with a full course of Albendazole therapy for 4 weeks. Six-month follow-up with TTE revealed complete healing of the apex defect without recurrence of the cyst. PMID:26702690

    Respiratory obstruction and stridor in infants and children are not uncommon. A rare cause of these sometimes life-threatening symptoms is the congenital saccular cyst. Objectives: We present the case of a 5-year-old girl with a cervical tumor, which appeared after a laryngeal endoscopic surgery of a saccular cyst with two relapses and a particular local evolution of its recurrence through the cricothyroid membrane. Material and method: The patient data has been reviewed over the entire follow-up period and a thorough an analysis of her investigations and surgery was performed. Results: The unusual evolution of this case was marked by an atypical exteriorization – not found in the published literature. The surgical approach was external, by paramedian thyrotomy, with no further long-term recurrence. Conclusions: An accurate diagnosis of saccular cysts can be made with the help of medical history, by an endoscopic visualization of the lesion and by the CT-scan imaging of the cervical region. Sometimes, saccular cysts can extend beyond laryngeal limits, determining fluid-filled tumors in the cervical region. PMID:27453755

    The identification and quantification of Heterosigma akashiwo cysts in sediments by light microscopy can be difficult due to the small size and morphology of the cysts, which are often indistinguishable from those of other types of algae. Quantitative real-time PCR (qPCR) based assays represent a potentially efficient method for quantifying the abundance of H. akashiwo cysts, although standard curves must be based on cyst DNA rather than on vegetative cell DNA due to differences in gene copy number and DNA extraction yield between these two cell types. Furthermore, qPCR on sediment samples can be complicated by the presence of extracellular DNA debris. To solve these problems, we constructed a cyst-based standard curve and developed a simple method for removing DNA debris from sediment samples. This cyst-based standard curve was compared with a standard curve based on vegetative cells, as vegetative cells may have twice the gene copy number of cysts. To remove DNA debris from the sediment, we developed a simple method involving dilution with distilled water and heating at 75°C. A total of 18 sediment samples were used to evaluate this method. Cyst abundance determined using the qPCR assay without DNA debris removal yielded results up to 51-fold greater than with direct counting. By contrast, a highly significant correlation was observed between cyst abundance determined by direct counting and the qPCR assay in conjunction with DNA debris removal (r2 = 0.72, slope = 1.07, p < 0.001). Therefore, this improved qPCR method should be a powerful tool for the accurate quantification of H. akashiwo cysts in sediment samples. PMID:26741648

    This case describes a 46-year-old woman with local pelvic and perineal pain, persisting for 2 years at presentation. The pain worsened during the night and morning and was alleviated during daily activities. Low back pain was associated with morning stiffness lasting longer than 2 h. Sometimes, she felt pain and numbness along her left S1 dermatome, without overt bladder or bowel incontinence. Lasegue's sign was negative. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were elevated (35 mm/h and 9.4, respectively) and Mennel's sign was present on both sides, indicating possible inflammation of the sacroiliac joints. However, radiographs of the lumbosacral spine and sacroiliac joints were normal. Magnetic resonance imaging (MRI) revealed a large spinal meningeal cyst in the sacrum (60 × 37 × 22 mm) consisting of multiple perineural cysts. The cyst eroded the surrounding sacral bone structures, narrowed several sacral foramina, and compressed neighboring nerve fibers. MRI findings on sacroiliac and hip joints were normal.

    A 62-year-old male developed a solitary asymptomatic nodule on the lateral aspect of the distal interphalangeal joint of the right great toe. Histopathologic findings demonstrated a myxoid cyst with a concomitant epidermal inclusion cyst. To the best of our knowledge, this is the first case of concurrent occurrence of digital myxoid cyst and epidermal inclusion cyst. Although the exact mechanism for developing a digital myxoid cyst and an epidermal inclusion cyst simultaneously at the same site is not explained, trauma might be a possible cause.

    Historically, tumor-like lesions of bone were defined as non-neoplastic bone lesions. Today, however, some of them are considered real neoplasms. They are among the most frequent bone lesions. They usually grow slowly, but occasionally they grow rapidly. Many of them can be diagnosed by plain films alone; in others, CT and MRI yield additional features for a correct diagnosis. Some lesions do not need treatment; others should be resected, and some may even recur. Non-ossifying fibroma, juvenile and aneurysmal bone cysts, fibrous and osteofibrous dysplasia and eosinophilic granuloma are presented. PMID:27216410

    A simple spectrophotometric method is developed here for the determination of phosphate present in the samples of soil, detergents, water, bone and food based on the formation of phosphomolybdate complex with the added molybdate followed by the reduction of the complex with thiourea in aqueous sulfuric acid medium. The system obeys Beer's law at 840 nm in the phosphate concentration range, 0.5-10.0 μg/ml. Molar absorptivity, correlation coefficient and Sandell's sensitivity values are found to be 1.712 mol -1 cm -1, 0.9769 and 0.0555 μg cm -2 respectively. For a comparison of the results determined from the developed method, phosphate present in the same set of samples is determined separately following an official method. The results of the developed method are agreeing well with those of the official phosphomolybdate method.

    2015-01-01

    Introduction: Pigmented villonodular synovitis is an uncommon disease characterized by hyperplastic synovium, large effusions and bone erosions. It commonly mimics other conditions. As a result, the diagnosis may remain elusive, as the classic signs of tenderness and effusion are not specific. Occasionally, PVNS presents as a popliteal cyst, which may divert attention from intra-articular pathology. In this article, we describe a case of pigmented villonodular synovitis that presented with a popliteal cyst as the chief problem. Case Report: A twelve year old boy presented to us with a history of a gradually enlarging mass in the left popliteal fossa since eighteen months. He complained of restriction of terminal knee flexion, but he had no pain. After clinical examination and imaging the mass was interpreted as being either a popliteal cyst or chronic hematoma without ruling out the possibility of soft tissue sarcoma. An open excisional biopsy of the lesion was performed which revealed a reddish-brown cystic-nodular mass communicating with the knee joint. The histology was consistent with that of pigmented villonodular synovitis. We performed an arthroscopic synovectomy 3 weeks later. Abnormal synovium found in all compartments of the knee was removed. Histology from the intra-articular lesion was also consistent with a diagnosis of pigmented villonodular synovitis. Conclusion: A swelling in the popliteal region may be due to various etiologies. The cause should be thoroughly investigated. Along with clinical examination and imaging the tissue must be subjected to histopathological examination. Pigmented villonodular synovitis can rarely present as a popliteal cyst. In such a situation, treatment consists of dealing with intra-articular and extra-articular pathology. PMID:27299073

    Radicular cysts are inflammatory jaw cysts confined to the apices of teeth with infected and necrotic pulp. They arise from the epithelial residues in the periodontal ligament as a result of inflammation, following the death of pulp. The treatment of such lesions vary with regard to their sizes; the small cystic lesions heal after an endodontic therapy, but larger lesions, may require additional treatment. Apical surgery for radicular cysts generally involves apical root resection and sealing with endodontic material. This case report, describes the treatment of a cyst related to the maxillary central and lateral incisors using platelet rich fibrin along with synthetic nanocrystalline hydroxyapatite granules for the regeneration of lost tissues. A follow-up evaluation at 6 months and 1-year revealed a significant radiographic bone fill with satisfactory healing at the surgical site. PMID:27538563

    One of the consequences of traumatic injuries is the chance of aseptic pulp necrosis to occur which in time may became infected and give origin to periapical pathosis. Although the apical granulomas and cysts are a common condition, there appearance as an extremely large radiolucent image is a rare finding. Differential diagnosis with other radiographic-like pathologies, such as keratocystic odontogenic tumour or unicystic ameloblastoma, is mandatory. The purpose of this paper is to report a very large radicular cyst caused by a single mandibular incisor traumatized long back, in a 60-year-old male. Medical and clinical histories were obtained, radiographic and cone beam CT examinations performed and an initial incisional biopsy was done. The final decision was to perform a surgical enucleation of a lesion, 51.4 mm in length. The enucleated tissue biopsy analysis was able to render the diagnosis as an inflammatory odontogenic cyst. A 2 year follow-up showed complete bone recovery. PMID:26393219

    Hydatid cysts are usually located in the liver and lungs. Skeletal echinococcosis is relatively rare and that of the rib is exceptional. Less than 50 cases of costal echinococcosis have been reported in the literature so far. To our knowledge, only one case report of thoracic outlet syndrome due to echinococcal cyst in the first rib was described in 1995. Accurate pre-operative diagnosis is important but may be challenging in some cases. Reported here is a case of echinococcosis of the first rib in a young adult who was presented with thoracic outlet syndrome. Plain chest radiograph, CT scan and MRI were performed. The imaging features were suggestive of a solitary aneurysmal bone cyst and the differential diagnosis included echinococcosis of the first rib. The lesion was completely resected and the histopathological examination confirmed the diagnosis of echinococcosis. PMID:22131660

    The synovial and ganglion cysts originating from the facet joint have been named under the name of the Juxtafacet cyst by the several researchers. They put forward that the synovial cyst originated from the synovial joint. But, they failed to clarify the pathophysiology of the formation of the ganglion cyst. In this case report, we reported a 67-year-old male patient was referred to the emergency from another center with the complaint of a left leg pain and weakness in the left foot and patient was treated with microchirurgical technique. His patological examination was evaluated a ganglion cyst. We have discussed and explained the pathophysiology of the formation of a ganglion cyst derivered from a synovial cyst. And separately, we have presented the spinal cysts by grouping them under a new classification called a cystic formation of the soft tissue attachments of the mobile spine as well as dividing them into sub-groups.

    Proper disposal of carcasses and offal after home slaughter is difficult in poor and remote communities and therefore dogs readily have access to hydatid cysts containing offal from livestock, thus completing the parasite cycle of Echinococcus granulosus and putting communities at risk of cystic echinococcosis. Boiling livers and lungs which contain hydatid cysts could be a simple, efficient and energy- and time-saving way to kill the infectious protoscoleces. The aim of this study was to provide precise practical recommendations to livestock owners. Our results show that boiling the whole sheep liver and/or lung, with single or multiple hydatid cysts, for 30 min is necessary and sufficient to kill E. granulosus protoscoleces in hydatid cysts. Advertising on this simple rule in at-risk communities would be an efficient and cheap complement to other veterinary public health operations to control cystic echinococcosis. PMID:25456565

    Hydatid disease is a zoonosis that can involve almost any organ in the human body. After the liver, the lungs are the most common site for hydatid disease in adults. Imaging plays a pivotal role in the diagnosis of the disease, as clinical features are often nonspecific. Classical radiological signs of pulmonary hydatid cysts have been described in the literature, aiding in the diagnosis of the disease. However, complicated hydatid cysts can prove to be a diagnostic challenge at times due to their atypical imaging features. Radiography is the initial imaging modality. Computed tomography can provide a specific diagnosis in complicated cases. Ultrasound is particularly useful in peripheral lung lesions. The role of magnetic resonance imaging largely remains unexplored. PMID:27358685

    Many chrysophyte algae produce morphologically distinctive, siliceous, microscopic cysts during a resting stage of their life cycles; these cysts are often preserved in sediments. Scanning electron microscopy and Nomarski optics permit much more detailed observation of these cysts than was heretofore possible. Many cyst types are found only in specific habitats, such as montane lakes, wet meadows, ephemeral ponds, and Sphagnum bogs. In the samples studied, cysts seem to be most common in fluctuating fresh-water habitats of low to moderate pH and some winter freezing. Chrysophyte cysts have the potential to be a useful tool for modern environmental assessments and paleoecological studies of Cenozoic fresh-water lacustrine deposits. -from Authors

    Radicular cysts are inflammatory odontogenic cysts of tooth bearing areas of the jaws. Most of these lesions involve the apex of offending tooth and appear as well-defined radiolucencies. Owing to its clinical characteristics similar to other more commonly occurring lesions in the oral cavity, differential diagnosis should include dentigerous cyst, ameloblastoma, odontogenic keratocyst, periapical cementoma and Pindborg tumour. The present case report documents a massive radicular cyst crossing the midline of the palate. Based on clinical, radiographical and histopathological findings, the present case was diagnosed as an infected radicular cyst. The clinical characteristics of this cyst could be considered as an interesting and unusual due to its giant nature. The lesion was surgically enucleated along with the extraction of the associated tooth; preservation of all other teeth and vital structures, without any postoperative complications and satisfactory healing, was achieved.

    Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland) and the oral cavity (usually the floor of the mouth). there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC) can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography. It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management. PMID:25210369

    Esophageal duplication cyst is a rare congenital anomaly resulting from a foregut budding error during the fourth to sixth week of embryonic development. Cervical esophageal duplication cysts are very rare and may cause respiratory distress in infancy. A full-term newborn girl who was born by normal delivery was transferred to our hospital because of swelling of the right anterior neck since birth. Cervical ultrasonography showed a 40 × 24 × 33 mm simple cyst on the right neck. Tracheal intubation was required at 2 weeks of age because of worsening external compression of the trachea. Fine-needle aspiration cytology revealed the existence of ciliated epithelium. At 1 month of age, exploration was performed through a transverse neck incision. The cyst had a layer of muscle connected to the lateral wall of the esophagus. Histopathological diagnosis was a cervical esophageal duplication cyst. We describe the clinical features of infantile cervical esophageal duplication cysts based on our experience of this rare disease in a neonate, along with a review of 19 cases previously reported in literature.

    In cases where the Weibull probability distribution is being investigated as a possible fit to experimentally obtained results of a random variable (V), there is, currently, no accurate and reliable but simple-to-use method available for simultaneously (a) establishing if the fit is of the two- or three-parameter variant of the distribution, and/or (b) estimating the minimum value of the variable (V(0)), in cases where the three-parameter variant is shown to be applicable. In the present work, the details of such a method -- which uses a simple nonlinear regression analysis -- are presented, together with results of its use when applied to 4 sets of number-of-cycles-to-fracture results from fatigue tests, performed in our laboratory, using specimens fabricated from 3 different acrylic bone cement formulations. The key result of the method is that the two- or three-parameter variant of the probability distribution is applicable if the estimate of V(0) obtained is less than or greater than zero, respectively.

    The incidence of epidermoid tumors is between 1% and 2% of all intracranial tumors. The usual locations of epidermoid tumor are the parasellar region and cerebellopontine angle, and it is less commonly located in sylvian fissure, suprasellar region, cerebral and cerebellar hemispheres, and lateral and fourth ventricles. Epidermoid cysts located in the posterior fossa usually arise in the lateral subarachnoid cisterns, and those located in the brain stem are rare. These epidermoids contain cheesy and flaky white soft putty like contents. Epidermoid cysts are very slow growing tumors having a similar growth pattern of the epidermal cells of the skin and develop from remnants of epidermal elements during closure of the neural groove and disjunction of the surface ectoderm with neural ectoderm between the third and fifth weeks of embryonic life. We are presenting an interesting case of intrinsic brainstem epidermoid cyst containing milky white liquefied material with flakes in a 5-year-old girl. Diffusion-weighted imaging is definitive for the diagnosis. Ideal treatment of choice is removal of cystic components with complete resection of capsule. Although radical resection will prevent recurrence, in view of very thin firmly adherent capsule to brainstem, it is not always possible to do complete resection of capsule without any neurological deficits.

    A 67-year-old man presented with persistent penis and scrotum pain due to S-2 and S-3 radiculopathy caused by a sacral perineural cyst. The cyst was treated with microsurgical partial cyst removal and cyst wall imbrication, together with closure of the point through which cerebrospinal fluid (CSF) flowed from the subarachnoid space into the cyst cavity. His pain resolved without recurrence of the cyst or complications. Symptomatic perineural cysts are quite rare. Surgical closure of the point through which CSF flows from the subarachnoid space into the cyst cavity is the most important intervention for symptomatic perineural cysts. If the source of CSF leakage cannot be detected, placement of a cyst-subarachnoid shunt should be considered in addition to partial cyst removal and cyst wall imbrication. PMID:22198114

    Giant cell tumors of the tendon sheath are common lesions and are the second most frequent tumors in the hand, after synovial cysts. They are diagnosed by means of clinical examination and complementary examinations (simple radiography and magnetic resonance). Erosion and invasion of the phalangeal bone affected may be seen on radiological examination. Magnetic resonance may show a “fluorescent or radiant effect” may be observed, caused by the high quantity of hemosiderin inside the tumor. Surgical treatment is the commonest practice, and complete excision is important for avoiding recurrence of the tumor, especially when bone invasion is observed on imaging examinations, which is generally related to greater tumor recurrence. In this paper, a case of a giant cell tumor of the tendon sheath in the middle phalanx of the third finger of a 45-year-old female patient is presented. This was successfully treated by means of surgery using a double access approach (dorsal and volar). PMID:27026996

  18. Combined Deletion of Vhl and Kif3a Accelerates Renal Cyst Formation.

    A subset of familial and sporadic clear cell renal cell carcinomas (ccRCCs) is believed to develop from cystic precursor lesions. Loss of function of the von Hippel-Lindau tumor suppressor gene (VHL) predisposes renal epithelial cells to loss of the primary cilium in response to specific signals. Because the primary cilium suppresses renal cyst formation, loss of the cilium may be an initiating event in the formation of ccRCC. To test this hypothesis, we analyzed the consequences of inducible renal epithelium-specific deletion of Vhl together with ablation of the primary cilium via deletion of the kinesin family member 3A (Kif3a) gene. We developed a microcomputed tomography-based imaging approach to allow quantitative longitudinal monitoring of cystic burden, revealing that combined loss of Vhl and Kif3a shortened the latency of cyst initiation, increased the number of cysts per kidney, and increased the total cystic burden. In contrast with findings in other cystic models, cysts in Kif3a mutant mice did not display accumulation of hypoxia-inducible factor 1-α (HIF1α), and deletion of both Hif1a and Kif3a did not affect cyst development or progression. Vhl/Kif3a double mutation also increased the frequency of cysts that displayed multilayered epithelial growth, which correlated with an increased frequency of misoriented cystic epithelial cell divisions. These results argue against the involvement of HIF1α in promoting renal cyst growth and suggest that the formation of simple and atypical renal cysts that resemble ccRCC precursor lesions is greatly accelerated by the combined loss of Vhl and the primary cilium.

    Conjunctival melanoma is the second most common conjunctival malignancy. Its differential diagnosis with other conjunctival melanocytic neoplasms is inherently difficult. The presence of epithelial cysts is a useful feature in conjunctival tumors and favors a benign lesion. Herein 2 cases of conjunctival melanoma with cysts are presented. To the best of our knowledge, this is the first series of conjunctival melanoma with epithelial inclusion cysts. This series emphasizes the importance of considering several malignant features when reviewing conjunctival melanocytic lesions, as malignancy can exist even in the presence of epithelial inclusion cysts.

    Hydatid disease is the most common infections worldwide, but it rarely involves multiple organs. Herein, a 12-year-old boy is presented, who was admitted to Children's Medical Center, Tehran University of Medical Sciences, Tehran, Iran with symptoms of irritability, sleepless, and weakness of the extremities. Patient's brain computed tomography (CT) scan with contrast media showed large multilocular cystic lesions in right temporal lobe associated with two other smaller similar cystic lesions in centrum semiovale bilaterally. Abdominal sonography revealed intestinal mesenteric and a cardiac cyst. Abdomino-pelvic CT scan showed a cyst medial to the cecum and a cortical cyst in the left kidney as well as a heart cyst. The echocardiography confirmed hydatid cysts at apical and interventricular septum. Serology test was positive for hydatid cyst. Albendazole and praziquantel were started for the patient immediately and right temporal lobe lesions were removed via neurosurgery intervention. After one month, cardiac and mesenteric cysts were operated during two separate surgeries. Pathologic findings of all cysts were compatible with hydatid cyst. Cystic hydatidosis should be suspected in any cystic mass, whilst prompt diagnosis and appropriate treatments are the keys in management of affected patients. PMID:22347246

    Introduction Progress in the development of surgical techniques has led to the growing use of video-assisted thoracoscopic surgery (VATS) techniques in mediastinal cyst treatment. Aim To present our experience of treating mediastinal cysts with the minimally invasive technique. Material and methods Fifty patients with mediastinal cysts were treated from 2001 to 2011. There were 32 women and 18 men. The age of the patients ranged from 17 to 72, the mean age being 42 years. All patients underwent basic preoperative diagnostic tests of the chest: X-ray, computed tomography (CT), bronchoscopy and spirometry; 4 patients underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and 3 fine needle aspiration biopsy (FNAB) of the described lesions. Results The VATS was performed in each case. Conversion was carried out due to superior mediastinal location in 10 cases and pleural adhesions in 3 cases. The partial resection of a cyst was performed in 3 patients. One patient was treated conservatively due to heart failure. In that patient the transthoracic needle aspiration of a cyst under ultrasound guidance using alcoholisation with 76% ethanol with a good effect was performed twice. Cyst recurrence was observed in 1 case. Conclusions The surgical access depends on the location of a cyst. The VATS resection of a superior mediastinal cyst is not always feasible. Surgery of mediastinal cysts is both diagnostic and curative. PMID:25337163

    Sacral perineural cyst is a relatively rare condition. To our knowledge, reports of MR findings associated with sacral perineural cyst have been limited to only six cases. We present for the first time high field MR findings in a case of sacral perineural cyst. The cyst appeared as a cystic lesion in the sacral spinal canal and had intermediate signal intensity on T1W images and high signal intensity on T2*W images compared with CSF. Slight erosion remodeling of the sacrum was also seen anteriorly. Our case was symptomatic and present with radiculopathy (sciatic pain). Surgical treatment was done to result in dramatic improvement of the sciatic pain. PMID:1337620

    Echinococcosis is endemic in various regions of Turkey. Cardiac involvement in echinococcosis is rare, and lone cardiac hydatid cysts are even more unusual. Because cardiac hydatid disease can be fatal, even asymptomatic patients are optimally referred for surgical treatment. We present a rare case of a lone, primary, mobile hydatid cyst in the left atrium of a 62-year-old woman. The cyst caused dyspnea from left ventricular inflow obstruction. In addition to reporting the patient's fatal case, we discuss cardiac hydatid cysts in terms of the scant medical literature. PMID:27303247

    Bronchogenic cysts are congenital sacs that result from maldevelopment of the primitive foregut. Although they occur predominantly in the chest, there are reports of lesions in extrathoracic locations. The majority of reported bronchogenic cysts located in the neck are found in the pediatric population; a review of the literature reveals few reports of bronchogenic cysts of the neck among adults. The diagnosis of a bronchogenic cyst relies on the histology and location of the lesion. Here, we review our experience in the diagnosis and management of 2 adult patients with pathologically proven bronchogenic cysts. Both patients presented with solitary neck masses that proved to be bronchogenic cysts on histologic examination. Our purpose is to define the histopathologic and clinical characteristics of bronchogenic cysts and discuss the features that distinguish them from other cervical cysts. In conclusion, congenital bronchogenic cysts can occur in the neck of adults and should be considered in the differential diagnosis of cystic cervical masses in adults, as well as children.

Aortic wall is a very unusual site for the hydatid cysts. To the best of our knowledge, this is the first reported case of hydatid cyst located within the aortic arch lumen. Patient underwent ascending aortic and hemiarch replacement under hypothermic circulatory arrest and removal of the cyst. Patient had an uneventful recovery and has been on follow-up. Although the literature data are very limited, we believe that the aortic procedure of choice should be graft interpositon rather than patch repair. PMID:17215134

    Background Medial patellofemoral ligament (MPFL) reconstruction has become an accepted technique to treat patellofemoral instability, and numerous surgical techniques have been described to reconstruct the MPFL. We describe a MPFL reconstruction procedure where bone-fascia tunnel fixation occurs at the medial margin of the patella for recurrent patellar dislocation. Objective MPFL reconstruction is the preferred operative treatment for recurrent patellar dislocation. The purpose of this study was to report a simple technique for reconstruction of medial patellofemoral ligament with bone-fascia tunnel fixation at the medial margin of the patella for recurrent patellar dislocation and to evaluate the results at 6-year-minimum follow-up. Methods The study included 65 patients (28 males, 37 females; mean age, 29.4 ± 5.6 years) who underwent MPFL reconstruction using the bone-fascia tunnel fixation at the medial margin of the patella technique and who were followed for a mean duration of 78.5 ± 3.8 months. Objective assessment, Kujala scale, Lysholm score, and Tegner activity score were obtained preoperatively and at the time of final follow-up. Results There were no patellar complications, including redislocation, in the present study. The congruence angle had significant improvement from 19.2° ± 6.3° before surgery to −6.03° ± 0.50° at the last follow-up. The lateral patellar angle had significant improvement from −6.9° ± 3.5° before surgery to 5.1° ± 2.4° at the last follow-up. The patellar tilt angle had significant improvement from 24.5° ± 5.2° before surgery to 12.30° ± 1.90° at the last follow-up. The Kujala score was significantly increased from 52.9 ± 3.2 points preoperatively to 90.1 ± 5.8 points postoperatively (P < 0.05). The mean Lysholm score was significantly increased from 47.2 ± 5.2 to 92.5 ± 6.2 points postoperatively (P < 0.05). The Tegner activity score improved

    The present short communication puts on record a case of bilateral, multiple follicular cysts in a water buffalo along with a detailed description of its ovarian biometry and follicular fluid composition. The ovarian weight and biometrical parameters were much higher than in normal cycling buffaloes. A total of three follicular cysts were observed, two on the right ovary and one on the left ovary, measuring 4.9, 3.0 and 2.6 cm yielding 21, 9 and 5 ml of follicular fluid, respectively. The cystic fluid was deep yellow in colour with a viscous consistency. The follicular fluid concentrations of glucose, total protein, cholesterol, acid phosphatase, calcium, phosphorus and progesterone in all the cysts were within the range reported previously in normal buffalo follicular fluid; however, the alkaline phosphatase concentration in cyst 1 and total bilirubin concentration in cysts 1 and 2 were higher than the values in normal follicular fluid. In contrast, the levels of urea nitrogen in cysts 1 and 3, and oestradiol in cyst 3 were lower than the normal values. All the three follicles had an oestradiol to progesterone ratio less than 1. The results of our study suggest that follicular cysts in buffalo are oestrogenically inactive and have an altered concentration of certain biochemical and hormonal constituents. PMID:21086160

    Background: Different research groups reported a negative correlation between cancers and parasitical infections. As an example, the prevalence of a hydatid cyst among patients with cancer was significantly lower than its prevalence among normal population. Tn antigens exist both in cancer and hydatid cyst. This common antigen may be involved in the effect of parasite on cancer growth. So in this work, common antigens between hydatid cyst and cancers have been investigated. Materials and Methods: Different hydatid cyst antigens including hydatid fluid, laminated and germinal layer antigens, and excretory secretory antigens of protoscolices were run in SDS PAGE and transferred to NCP paper. In western immunoblotting, those antigens were probed with sera of patients with different cancer and also sera of non-cancer patients. Also, cross reaction among excretory secretory products of cancer cells and antisera raised against different hydatid cyst antigen was investigated. Results: In western immunoblotting, antisera raised against laminated and germinal layers of hydatid cyst reacted with excretory secretory products of cancer cells. Also, a reaction was detected between hydatid cyst antigens and sera of patients with some cancers. Conclusion: Results of this work emphasize existence of common antigens between hydatid cyst and cancers. More investigation about these common antigens is recommended. PMID:26962511

    A 25-year-old man presented with left lumboischialgia refractory to medical treatment. Neurological examination revealed L5 and S1 radiculopathy which rapidly worsened over a short period. Magnetic resonance imaging demonstrated disk bulging with a discal cyst at the L4-5 intervertebral space and disk herniation at the L5-S1 intervertebral space. Computed tomography showed osteolytic change of the L5 vertebral body adjacent to the cyst. Resection of the cyst and removal of the herniated disk were performed following fenestration of the L4-5 and L5-S1 interlaminar spaces. Bloody serous fluid followed by clear serous fluid was recognized during the aspiration and partial resection of the cyst at the L4-5 level. Histological examination demonstrated a cyst wall consisting of fibrous connective tissue without a single-layer lining of cells, and fibrin deposits. The patient's symptoms disappeared immediately after the operation. This osteolytic lumbar discal cyst possibly occurred subsequent to hemorrhage from the epidural venous plexus following intervertebral disk injury, hematoma encapsulation by connective fibrous tissue, and cyst wall formation in reaction to the disk injury and hemorrhage. The cyst may have enlarged due to the inflow of the serous fluid from the water-containing degenerated disk. PMID:18719328

    Abstract We performed a dynamic study of arachnoid cysts (ACs) using magnetic resonance cisternography (MRC) and proposed a classification of ACs. Twenty-three suitable patients in our hospital entered into this study according to our inclusion criteria. MRC images were collected in all the subjects at 1 and 24 hours after the administration of intrathecal gadolinium-diethylenetriamine penta-acetic acid (Gd-DTPA). We allocate the enrolled patients into 2 groups, MRC group and surgery group. The MRC results were considered before treatment in 1 group (MRC group, 13 patients), whereas another group was surgically treated without considering the MRC results (surgery group, 10 patients). We calculated the enhanced area of cyst using modified MacDonald Criteria from the images and measured the surrounding subarachnoid area as the reference. We found that it was practically useful to quantify 3 types of ACs, complete communicating, incomplete communicating, and noncommunicating, according to MRC results in this study. All the subjects in both groups are closely observed before the treatment and the follow-up using the MRI examination. In the surgery group, 5 patients were found that the area of cysts shrank in the follow-up stage. However, there was no significant difference in the percentage shrinkage area between the 2 groups. We concluded that MRC with Gd-DTPA as a contrast agent is of significant clinical value for the diagnosis and treatment of children with intracranial ACs. This classification based on dynamic MRC is useful for making surgical recommendations. PMID:26554773

    Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between the reduced enamel epithelium and the tooth crown of an unerupted tooth. Management of dentigerous cyst in primary dentition needs special consideration regarding the preservation of the developing permanent tooth buds. A case of dentigerous cyst is reported in primary dentition of a 7-year-old female patient and its management. By extracting the infected primary teeth, opening the cyst and ensuring continuous drainage, it is possible to achieve spontaneous eruption of the involved permanent teeth into the dental arch even if they are badly dislocated. Simultaneous with the eruption of the permanent teeth, ossification of the bony defect can take place. The reparatory process is completed in one to two years, during this time the patient has been given a space-maintainer. PMID:23387129

    2014-01-01

    A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. It is often asymptomatic and therefore it is usually found as an incidental finding. Preoperative diagnosis may be possible with computed tomography and magnetic resonance imaging. However, the correct diagnosis can only be made with histology. The first-choice therapy is the complete removal of the cyst, which must be accurately planned according to the anatomy of the lesion, its dimensions and its relationships with major abdominal structures. We present two clinical cases: the one of a 30-year-old man with a mesenteric cyst that was removed by laparoscopy and the other of a 61-year-old woman who underwent open excision of a huge retroperitoneal cyst.

    19 children were diagnosed with abdominal cysts of different origin in the Surgical Unit of the Department of Pediatrics, Medical University of Pécs, Hungary between 2010 and 2013. The authors discuss the details of representative cases of a parovarial cyst, an intestinal duplication, and an omental cyst with emphasis on the clinical symptoms, diagnostic tools, and surgical interventions. The authors conclude that abdominal cysts often cause mild symptoms only, and they are discovered accidentally by ultrasound imaging performed for other reasons. In some cases, the cyst can cause severe complaints or even acute abdomen requiring emergency surgery. Laporoscopy may be a valuable method both in diagnosis and surgical therapy. Abdominal CT or MRI are not required in the majority of the patients. PMID:26552027

    Paratracheal air cysts are a rare entity in which cystic formation occurs adjacent to the trachea. Most patients with paratracheal air cysts are asymptomatic, and the cysts are detected incidentally on chest radiograph or computed tomography (CT) scan. Most symptomatic patients complain of pulmonary symptoms or repeated respiratory infection. Rarely, the air cysts can lead to paralysis of the recurrent laryngeal nerve as a result of direct compression. We report a case of a 59-year-old male patient who presented with voice change, and the cause was identified as paratracheal air cysts on a chest CT scan. Surgical resection via video-assisted mediastinoscopy was performed, and the voice recovered immediately after the operation. PMID:27525245

    Congenital vitelline duct anomalies other than Meckel’s diverticulum are rare in animals. A cyst of approximately 8 mm in diameter was observed on the antimesenteric surface of the ileal serosa in a 10-week-old female Crl:CD(SD) rat. Microscopically, the cyst closely resembled the ileum, but it did not communicate with the ileal lumen. We diagnosed this case as a vitelline cyst derived from the vitelline duct based on the location where it developed and its histological behavior. In rats, only Meckel’s diverticulum has been reported with a congenital anomaly of the vitelline duct, and no other spontaneous anomalies including a vitelline cyst have been reported. This case may be the first report concerning a vitelline cyst in the rat ileum. PMID:26538812

    Nine dogs presenting for investigation of cervical or thoracolumbar myelopathies were diagnosed with extradural spinal synovial cysts. Degenerative disease affecting the articular facets or intervertebral discs was present on plain spinal radiographs in all cases. Myelography was consistent with dorsolateral, extradural spinal cord compression. Two groups of dogs were identified: (1) young, giant breed dogs with multiple cysts involving one or more levels of the cervical spinal cord; and (2) older, large breed dogs with solitary cysts involving the thoracolumbar spinal cord. The synovial cysts constituted the major compressive lesions in four of the dogs. Analysis of lumbar cerebrospinal fluid demonstrated albuminocytological dissociation, consistent with chronic compressive myelopathy, in six dogs. All dogs underwent decompressive surgery and the diagnosis of synovial cysts was confirmed histologically. The mean follow-up period was 17 months (range four to 36 months). At the time of follow-up, all dogs were fully ambulatory with improved neurological function compared with that at initial presentation. PMID:11688527

    Hydatid cyst (HC) in mediastinum is very rare. To the best of our knowledge, a case with multiple HCs in mediastinum is not reported already. We herein report a case of multiple HCs of the mediastinum and liver in a - 50 year-old woman presented with chest pain, cough and dyspnea for about two years. She had been treated for tuberculosis for 20 years. Chest CT scan showed multiple cysts in posterior mediastinum and one cyst in left lobe of liver. Via right posterolateral thoracotomy, multiple cysts were excised in mediastinum. And then, hepatic left lobe cyst was removed trans-diaphragmatically. Histopathologic examination confirmed HCs. Despite its rarity, primary HCs should be considered in the differential diagnosis of mediastinal multiple cystic lesions in endemic regions. PMID:20067057

  15. Toxicokinetics of bone lead.

    PubMed Central

    Rabinowitz, M B

    1991-01-01

    This article discusses bone as a source of lead to the rest of the body and as a record of past lead exposure. Bone lead levels generally increase with age at rates dependent on the skeletal site and lead exposure. After occupational exposure, the slow decline in blood lead, a 5- to 19-year half-life, reflects the long skeletal half-life. Repeated measurements of bone lead demonstrate the slow elimination of lead from bone. Stable isotope ratios have revealed many details of skeletal uptake and subsequent release. The bulk turnover rates for compact bone are about 2% per year and 8% for spine. Turnover activity varies with age and health. Even though lead approximates calcium, radium, strontium, barium, fluorine, and other bone seekers, the rates for each are different. A simple, two-pool (bone and blood) kinetic model is presented with proposed numerical values for the changes in blood lead levels that occur with changes in turnover rates. Two approaches are offered to further quantify lead turnover. One involves a study of subjects with known past exposure. Changes in the ratio of blood lead to bone lead with time would reflect the course of bone lead availability. Also, stable isotopes and subjects who move from one geographical area to another offer opportunities. Sequential isotope measurements would indicate how much of the lead in blood is from current exposure or bone stores, distinct from changes in absorption or excretion. PMID:2040248

    2016-03-28

    Cystic echinococcosis (CE) is a widely endemic helminthic disease caused by infection with metacestodes (larval stage) of the Echinococcus granulosus tapeworm. E. granulosus are common parasites in certain parts of the world, and are present on every continent with the exception of Antarctica. As a result, a large number of people are affected by CE. The increased emigration of populations from endemic areas where prevalence rates are as high as 5-10% and the relatively quiescent clinical course of CE pose challenges for accurate and timely diagnoses. Upon infection with CE, cyst formation mainly occurs in the liver (70%). Diagnosis involves serum serologic testing for antibodies against hydatid antigens, but preferably with imaging by ultrasound or CT/MRI. Treatment methods include chemotherapy with benzimidazole carbamates and/or surgical approaches, including percutaneous aspiration injection and reaspiration. The success of these methods is influenced by the stage and location of hepatic cysts. However, CE can be clinically silent, and has a high risk for recurrence. It is important to consider the echinococcal parasite in the differential diagnosis of liver cystic lesions, especially in patients of foreign origin, and to perform appropriate long-term follow-ups. The aim of this review is to highlight the epidemiology, natural history, diagnostic methods, and treatment of liver disease caused by E. granulosus. PMID:27047771

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe. PMID:26636254

  2. Strategies To Discover the Structural Components of Cyst and Oocyst Walls

    2013-01-01

    Cysts of Giardia lamblia and Entamoeba histolytica and oocysts of Toxoplasma gondii and Cryptosporidium parvum are the infectious and sometimes diagnostic forms of these parasites. To discover the structural components of cyst and oocyst walls, we have developed strategies based upon a few simple assumptions. Briefly, the most abundant wall proteins are identified by monoclonal antibodies or mass spectrometry. Structural components include a sugar polysaccharide (chitin for Entamoeba, β-1,3-linked glucose for Toxoplasma, and β-1,3-linked GalNAc for Giardia) and/or acid-fast lipids (Toxoplasma and Cryptosporidium). Because Entamoeba cysts and Toxoplasma oocysts are difficult to obtain, studies of walls of nonhuman pathogens (E. invadens and Eimeria, respectively) accelerate discovery. Biochemical methods to dissect fungal walls work well for cyst and oocyst walls, although the results are often unexpected. For example, echinocandins, which inhibit glucan synthases and kill fungi, arrest the development of oocyst walls and block their release into the intestinal lumen. Candida walls are coated with mannans, while Entamoeba cysts are coated in a dextran-like glucose polymer. Models for cyst and oocyst walls derive from their structural components and organization within the wall. Cyst walls are composed of chitin fibrils and lectins that bind chitin (Entamoeba) or fibrils of the β-1,3-GalNAc polymer and lectins that bind the polymer (Giardia). Oocyst walls of Toxoplasma have two distinct layers that resemble those of fungi (β-1,3-glucan in the inner layer) or mycobacteria (acid-fast lipids in the outer layer). Oocyst walls of Cryptosporidium have a rigid bilayer of acid-fast lipids and inner layer of oocyst wall proteins. PMID:24096907

    Cysts in the organs of the abdominal cavity revealed in ultrasonographic examinations in patients with none or with unclear clinical symptoms cause diagnostic and fitness for work assessment problems. The aim of the study was to evaluate the usefulness of ultrasonography of cysts, combined with biochemical, bacteriological, cytological examinations and analysis of markers CEA and AFP of the fluid collected with fine needle aspiration biopsy (FAB). The study material examined were maritime workers who were submitted to these examinations for diagnostic purposes and/or previous to issue of certificate of health for work at sea. Examinations results provided support for usefulness of the method discussed in diagnosis and differentiation of inflammatory and neoplastic processes with simple cysts. This was crucial for final diagnosis, for decision about treatment and recognizing fitness for work at sea. It was concluded that the method FAB is safe both in hospital as well as in ambulatory conditions. PMID:7580347

    Introduction. Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT) revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR) technique is another nonsurgical option. PMID:24790764

    Introduction. Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT) revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR) technique is another nonsurgical option. PMID:24790764

    Purpose and Introduction Dentigerous cysts are epithelial in origin and are the most commonly found cyst in children. The majority of these lesions are usually a radiological finding and are capable of quite large before being diagnosed. The standard treatment for these cysts is the enucleation and the extraction of the affected tooth. However, if the patient is a child and the affected tooth is not developed, a more conservative attitude should be considered. Material and Methods (Clinical case): A 7-year-old patient is presented with an eruptive backlog of the lower permanent first molars. Radiological examination reveals two radiolucid lesions in relation to them, which are compatible with a dentigerous cyst, and in relation to the inferior aveolar nerve and various germs. A partial enucleation is carried out, maintaining all the dental germs related to the cyst in mouth and monitoring the patient until the case study is over. Results and Discussion Diagnosis and early treatment of these lesions in children is of great importance, especially in cases where the lesions enclose permanent teeth. Conclusions Whenever possible, a conservative attitude should be taken, one that allows for the maintenance of the dentition and treatment of the associated cyst in order to not compromise either the occlusion or the mental state of these patients. Key words:Dentigerous cyst, conservative treatment, dental impaction, child. PMID:26644847

  9. Arthroscopic Decompression for a Giant Meniscal Cyst.

    The authors report the case of a giant medial meniscal cyst in an osteoarthritic knee of an 82-year-old woman that was successfully treated with only arthroscopic cyst decompression. The patient noticed a painful mass on the medial side of the right knee that had been gradually growing for 5 years. Magnetic resonance imaging showed an encapsulated large medial cystic mass measuring 80×65×40 mm that was adjacent to the medial meniscus. An accompanying horizontal tear was also detected in the middle and posterior segments of the meniscus. The medial meniscus was resected up to the capsular attachment to create bidirectional flow between the joint and the cyst with arthroscopic surgery. Magnetic resonance imaging performed 14 months postoperatively showed that the cyst had completely disappeared, and no recurrence was observed during a 2-year follow-up period. An excellent result could be obtained by performing limited meniscectomy to create a channel leading to the meniscal cyst, even though the cyst was large. Among previously reported cases of meniscal cysts, this case is the largest to be treated arthroscopically without open excision. PMID:26726987

    INTRODUCTION Hydatid disease is a parasitic infestation caused by the cystic stage of Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lung. Pancreatic affection by hydatid cysts is very rare even in endemic areas. PRESENTATION OF CASE Our case is a 34-year-old male patient referred to our centre with a pancreatic body cyst diagnosed by abdominal CT scan. The patient gave 3 months history of epigastric pain. He also gave history of travelling to Saudi Arabia and China. His enzyme-linked immunoadsorbent assay (ELIZA) test for echinococcal antigens was positive. Surgical exploration revealed a 7 cm cyst in the body of the pancreas separable from the surroundings. Endocystectomy and deroofing of the cyst was done. DISCUSSION Due to its rarity and similarity with more common pancreatic cystic conditions, diagnosis of pancreatic hydatid cyst may be challenging. Abdmonial sonography and CT scan together with enzyme-linked immunoadsorbent assay (ELIZA) test for echinococcal antigens are helpful diagnostic tools. Therapeutic options include endocystectomy and deroofing, albendazol therapy with percutaneous drainage or laparoscopic excision of the cyst. CONCLUSION Even in non-endemic areas, past history of travelling abroad in patients with pancreatic cystic lesions should raise the suspicion of hydatid disease as a possible diagnosis.

    Chronic compression by intracranial cystic lesions can cause cranial nerve palsies and bony changes. With the advent of imaging techniques, grossly accurate diagnosis is possible. However, few cases do surprise the clinicians both intra, and postoperatively. A 27-year-old male presented to us with complaints of double vision for 4 months followed by sharp, shooting pain in the left V1 and V2 distribution for 1-month duration, on examination, he had left lateral palsy and decreased pin prick and temperature sensation in V1 distribution. On computed tomography scan, a cystic lesion noted which is isodense in the middle cranial fossa with erosion of the underlying bone. On magnetic resonance imaging lesion was iso to hyperintense on T1-Weighted and hyperintense on T2-Weighted, brilliantly enhancing on contrast administration. Provisional diagnosis was trigeminal schwannoma, left temporal craniotomy and total excision of the cyst done. Histopathological examination showed cyst wall lined with collagen. Postoperatively patient neuralgic pain subsided with persisting sixth nerve palsy. PMID:26425164

    Cystic kidney disease includes a wide range of hereditary, developmental, and acquired conditions of the kidneys. Some of the inherited causes of cystic kidney disease include autosomal dominant polycystic kidney diseases (caused by mutations in PKD1 or PKD2), autosomal recessive polycystic kidney disease, tuberous sclerosis complex, von Hippel-Lindau disease, oral-facial-digital syndrome type I, and Hadju-Cheney syndrome. Acquired cystic kidney disease has been reported in patients receiving long-term hemodialysis or peritoneal dialysis and in children after liver transplantation. Acute kidney injury can occur in patients with neuroblastoma, usually as a result of thrombotic microangiopathy associated with bone marrow transplantation. End-stage renal disease is described in long-term survivors. However, in this case report, we provide what is to our knowledge the first description of multiple kidney cysts in long-term survivors of stage IV neuroblastoma. None of the 7 patients we describe with neuroblastoma and multiple kidney cysts had a family history of autosomal dominant polycystic kidney disease. Also, all lacked stigmata of tuberous sclerosis complex, von Hippel-Lindau disease, or Hadju-Cheney syndrome. Two patients progressed to end-stage renal disease; in addition, one of them developed an oncocytoid renal cell carcinoma. PMID:27016049

    Juxtafacet cysts are implicated in neural compression. Thus far, it is known that surgical removal is the definitive treatment for symptomatic juxtafacet cyst because spontaneous regression is rare, and the failure rate of conservative treatment is high. We have reported a rare case of right-sided juxtafacet cyst development after the spontaneous resolution of contralateral left-sided facet cyst. The left-sided facet cyst resolved spontaneously without surgical treatment, but a juxtacyst developed on the contralateral facet on the right side, as illustrated on 4-year follow-up magnetic resonance images. To the best of our knowledge, this is the first report of newly developed contralateral juxtafacet cyst after spontaneous regression. Herein, we have discussed the natural history and the management of this rare case. PMID:26819695

    Arachnoid cysts are cerebrospinal fluid collections in the spine that can present with neurological symptoms or be discovered accidentally. Intradural location of such cysts especially in the lumbosacral region is relatively rare. The association of such cysts with other congenital anomalies such as tethered cord lends evidence to the developmental origin of arachnoid cysts. We report a case of lumbosacral arachnoid cyst with tethered cord in a 6-year-old male child and discuss the etiopathogenesis and management options. PMID:24082689

    Cardiac hydatid cyst is life threatening but rare. It is usually asymptomatic and has potentially lethal complications, so early diagnosis with definitive treatment is life-saving. In the present article, we report two cases. The first is a 30-year-old woman with a primary large multivesicular hydatid cyst in the left ventricle. The second is a 17-year-old woman who had multivisceral involvement with a cardiac hydatid cyst, a congenital cardiac anomaly that was an atrial septal defect complicated by pulmonary hypertension. 2-D echocardiography and magnetic resonance imaging confirmed the diagnosis. Surgical treatment was performed using extracorporeal circulation and adjunctive albendazol therapy. PMID:16352080

    Perineural cysts are an uncommon radiological finding and a rare cause of radicular leg pain. We report the clinical findings, imaging and operative appearances of a patient who presented with radicular leg and perineal pain, which was found to be associated with multiple sacral perineural cysts. The diagnostic and treatment options are explored. In particular, the use of percutaneous fine-needle cyst drainage as a guide to the value of surgery is discussed. Postoperative complications, such as pseudomeningocoele can occur, but may be effectively treated with lumbar drainage. PMID:12046741

    Parathyroid cysts are rare causes of neck swelling accounting for 0.6% of thyroid and parathyroid lesions. They may be functional, resulting in the release of parathyroid hormone, or non-functional. Non-functional cysts may be cosmetically unacceptable or cause dysphagia, dyspnoea or recurrent laryngeal nerve palsy as a result of compression. This article presents a young woman who was diagnosed with a thyroid cyst both on examination and imaging. However, the final histology confirmed this to be parathyroid in origin and this should be considered in the differential of such neck swellings. PMID:22504755

    2014-07-01

    Bone marrow fat (BMF) results from an accumulation of fat cells within the bone marrow. Fat is not a simple filling tissue but is now considered as an actor within bone microenvironment. BMF is not comparable to other fat depots, as in subcutaneous or visceral tissues. Recent studies on bone marrow adipocytes have shown that they do not appear only as storage cells, but also as cells secreting adipokines, like leptin and adiponectin. Moreover bone marrow adipocytes share the same precursor with osteoblasts, the mesenchymal stem cell. It is now well established that high BMF is associated with weak bone mass in osteoporosis, especially during aging and anorexia nervosa. But numerous questions remain discussed: what is the precise phenotype of bone marrow adipocytes? What is the real function of BMF, and how does bone marrow adipocyte act on its environment? Is the increase of BMF during osteoporosis responsible for bone loss? Is BMF involved in other diseases? How to measure BMF in humans? A better understanding of BMF could allow to obtain new diagnostic tools for osteoporosis management, and could open major therapeutic perspectives. PMID:24703396

    Background: A rare cause of spinal cord compression is spinal arachnoid cysts. Symptoms are caused by spinal cord compression, however, asymptomatic patients have been also reported. Treatment options depend upon symptom severity and clinical course. Case Description: We report the case of a 47-year-old patient who developed an intramedullary arachnoid cyst after removal of an intradural extramedullary cyst. Conclusion: Surgery should be considered early in a symptomatic disease course. Longstanding medullary compression may reduce the possibility of neurological recovery as well as secondary complications such as intramedullary cyst formation. PMID:27512608

    Echinococcosis is a parasitic infection also called as hydatid disease or hydatidosis. Hydatidosis is a cyclo-zoonotic infection of the larvae form of Echinococcus granulosus (canine tapeworm). The majority of hydatid cysts are seen in the liver (65%) as most of the embryos are trapped within it. Infratemporal region is an unusual site for hydatidosis and has been sparsely reported in the literature. To the best of our knowledge, this is the fourth and perhaps the largest case report of hydatidosis involving the mandible in the literature in right infratemporal region involving the ramus condyle unit in a 35-year-old female with chief complaint of pain on right side of temporomandibular joint area on mastication, and opening and closing of mouth.

    Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death.

    A conjunctival cyst is a thin-walled sac or vesicle that contains fluid. This vesicle may develop either on or under the conjunctiva. It develops due to variety of causes such as infection, inflammation, retention cyst and rarely drug induced. The authors aimed to report a case of conjuctival cyst in a 34-year-old male following instillation of anti-allergic topical drugs for over period of one year. Conjuctival cyst developing due to chronic use of anti-allergic topical drugs containing preservatives is one of the complications associated with it. Presence of a preservative in an ocular medication has often been considered in damaging the epithelium. Inclusion of a preservative is equally necessary, especially in multiple-drug therapy in order to protect against dangerous organisms accidentally gaining access during instillation. Benzalkonium chloride (BAK), chlorobutanol, chlorhexidine acetate (CHA) and phenylmercuric nitrate or acetate are some commonly used preservatives in eye drops. PMID:26675748

    As technology advances, the techniques of laparoscopic surgery are being refined and their aplication is expanding to include many disease processes and organs. The new-generation laparoscopic instruments are becoming smaller (less than 5 mm). Expected advantages include improvements in cosmesis and patient satisfaction, and decreased postoperative analgesic requirements. Non-neoplastic cysts of the spleen are rare, and their management has evolved from total open splenectomy to laparoscopic cyst decapsulation. A 22-year-old woman with a symptomatic 10-cm epithelial cyst was treated by splenic decapsulation with needlescopic instruments (3 mm or smaller). Three trocars were used: one 12-mm umbilical and two 3-mm subcostal ports. The cyst was punctured by a Veress needle, and after drainage of straw-coloured fluid, circumferential decapsulation with 5-mm laparoscopic shears through the umbilical port site was done. The patient was discharged within 24 hours, having had a single intramuscular injection of meperidine and an excellent cosmetic result. PMID:10948693

    Purpose To report two cases of solitary unilateral vitreous cyst. Methods A complete ocular examination, fundus photography, B-scan ultrasound and spectral-domain optical coherence tomography were performed in both patients. Results The first patient (a 39-year-old man) presented with transient blurred vision in the right eye. The second patient (a 78-year-old man) reported transient blurred vision in the right eye when changing head position. He was referred to the Eye Hospital because of vitreomacular traction in the other eye. After examination, a diagnosis of vitreous cyst was made in both cases. Conclusions Vitreous cysts are rare clinical findings. They can occur in normal eyes or in eyes with certain ocular pathologies. When a cyst floats into the visual axis area, it can disturb visual function; therefore, patients usually report transient blurring of vision. A prompt clinical examination is necessary for differentiating this rare condition. PMID:24348410

    The cistern of the velum interpositum is a space located between the corpus callosum dorsally and the roof of the third ventricle ventrally. Lesions located within the velum interpositum are rare and include meningiomas, pilocytic astrocytomas, atypical teratoid/rhabdoid tumors and arachnoid cysts. Epidermoid cysts in this location have not been reported previously. We report the clinical and radiological features of two patients with epidermoid cysts located in the velum interpositum. The patients presented with gait difficulty and features of raised intracranial pressure and magnetic resonance imaging demonstrated large tumors in the velum interpositum with intensities suggestive of epidermoid cysts. There was ventral displacement of the internal cerebral veins and dorsal displacement of the corpus callosum in keeping with a mass in the velum interpositum. Tumors of the third ventricle displace the internal cerebral veins dorsally. A transcallosal approach was used in both patients to effectively excise the tumors. PMID:18710812

    Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up.

    The purpose of this study was to investigate the surgical outcomes and to determine indicators of the necessity of surgical intervention. Twelve consecutive patients harboring symptomatic sacral perineural cysts were treated between 1995 and 2003. All patients were assessed for neurological deficits and pain by neurological examination. Magnetic resonance of imaging, computerized tomography, and myelography were performed to detect signs of delayed filling of the cysts. We performed a release of the valve and imbrication of the sacral cysts with laminectomies in 8 cases or recapping laminectomies in 4 cases. After surgery, symptoms improved in 10 (83%) of 12 patients, with an average follow-up of 27 months. Ten patients had sacral perineural cysts with signs of positive filling defect. Two (17%) of 12 patients experienced no significant improvement. In one of these patients, the filling defect was negative. In conclusion, a positive filling defect may become an indicator of good treatment outcomes. PMID:16508691

    The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagnosis is primarily made clinically; if necessary, this is complemented by imaging. This paper reports the case of a 39-year-old male patient who complained of pain in the right upper premolar region and poor aesthetics due to a firm tumor in the right wing of the nose. Initially, this was thought to be due to an odontogenic abscess; however, the differential diagnosis was that a nasolabial cyst was communicating with the apex of teeth 14 and 15. Surgical treatment was carried out, followed by histopathological examination and concomitant endodontic treatment of the teeth involved. PMID:26904312

    The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagnosis is primarily made clinically; if necessary, this is complemented by imaging. This paper reports the case of a 39-year-old male patient who complained of pain in the right upper premolar region and poor aesthetics due to a firm tumor in the right wing of the nose. Initially, this was thought to be due to an odontogenic abscess; however, the differential diagnosis was that a nasolabial cyst was communicating with the apex of teeth 14 and 15. Surgical treatment was carried out, followed by histopathological examination and concomitant endodontic treatment of the teeth involved. PMID:26904312

    Dentigerous cyst (DC), also known as follicular cyst, is an odontogenic cyst with fluid accumulation between the crown and enamel organ of an unerupted tooth, pushing the crown away from the alveolar bone. The patients with DC in the maxillary sinus should be evaluated thoroughly by extraoral and intraoral examinations, proper diagnostic imaging procedures, and pathologic examination to avoid misdiagnosis of maxillary sinusitis. The standard treatment for DC in the maxillary sinus is often removed by Caldwell-Luc approach. Furthermore, marsupialization or functional endoscopic sinus surgery may be performed because of the size, location of the cysts, or the age of the patients. Sometimes, DC recurred and it made contour deformity. The buccal fat pad (BFP) was mentioned for the first time by Heister in 1732 and better described by Bichat in 1802. Egyedi was the first to report use of the BFP in oral reconstruction for the closure of oroantral and oronasal communications, and Tideman et al showed there was no need to cover BFP by a skin graft when used for defects of oral cavity. So, the authors report our experience with the bilateral pedicled sling BFP flap for intraoral reconstruction after larger recurrent DC removal and describe advantages, operative procedure, and possible complications of the DC.

    Glandular odontogenic cyst (GOC) is an uncommon jaw bone cyst of odontogenic origin described in 1987 by Gardner et al. It is a cyst having an unpredictable and potentially aggressive behaviour. It also has the propensity to grow to a large size and tendency to recur with only 111 cases having been reported thus far. The first case occurred in a 42-year-old female and presented as a localized swelling extending from 19 to 29 regions. There was a history of traumatic injury at the site. There was evidence of bicortical expansion and radiographs revealed a multilocular radiolucency. The second case occurred in a 21-year-old male, as a large swelling in the mandible and radiograph revealed radiolucency in the region. On histopathological examination, these lesions were diagnosed as GOC. It was concluded that, two cases submitted by us correlate with the existing literature that GOC’s affect more commonly in the middle age group, having predilection for mandible and that trauma could be a precipitating factor for its occurrence. The increased recurrence rates can be due to its intrinsic biological behavior, multilocularity of the cyst, and incomplete removal of the lining following conservative treatment. PMID:19644539

    A postmenopausal woman presented with enlarged breasts, increased vaginal mucus, and elevated serum estrogen and normal progesterone levels. A laparotomy was performed and revealed a cystic right ovary. Histologic examination of the ovary demonstrated a cyst lined by stratified lutein cells with abundant eosinophilic cytoplasm. The endometrium showed cystic and adenomatous hyperplasia. The diagnosis was functional lutein cyst. Removal of the cystic ovary reduced the estrogen levels, and the clinical picture reverted to that of a normal postmenopausal state. PMID:876536

    The occurrence of a ventral cystic lesion of the penis should alert the clinician to the diagnosis of a median raphe cyst. The lesions, which are most common near the glans penis, may occur anywhere from the urethral meatus to the anus. Cysts of the median raphe represent defects in the embryologic development of the genitalia and are usually lined by entodermal epithelium. Surgical excision is the treatment of choice. PMID:485186

    Cysts arising in the penis are uncommon and can be found anywhere from the urethral meatus to the root of the penis involving glans, foreskin, or shaft. Median raphe cysts account for the majority of penile cystic lesions reported in the literature. As their name suggests, they arise on the ventral midline of the penis that extends from the urethral meatus to the scrotum and perineum. Proposed hypotheses for their origin as well as their diverse morphology are discussed. PMID:25701383

    Clinical manifestations of empty sella syndrome include hypopituitarism cerebrospinal fluid rhinorrhea, headache, and visual abnormalities. A 21-year-old woman reported a 6-month history of worsening vision 3 years after decompression of a sellar-suprasellar Rathke cleft cyst. Her magnetic resonance imaging (MRI) showed a well-defined recurrent cyst in the sellar-suprasellar region causing chiasmatic compression. She underwent an endonasal, endoscopic decompression of the cyst, with subsequent improvement in her vision. A postoperative computed tomography confirmed good decompression of the cyst. Ten days after surgery, she reported sudden loss of vision in both eyes. MRI revealed an empty sella with herniation of both anterior cerebral arteries and optic chiasm into the sella. She underwent transnasal packing of the sellar floor with fat graft and bone plaques, and experienced gradual improvement in vision in her right eye. PMID:26828843

    Eleven patients with sharply circumscribed round to ovoid renal cysts measuring 70-90 H on CT are reported. The cysts were hyperdense on unenhanced scans, measuring 30-60 H greater than the adjacent parenchyma, and either hypodense, isodense, or hyperdense on enhanced scans. Four patients had polycystic kidney disease; of the other 7 patients, the cysts were cortical in 6 and parapelvic in 1. Eight patients had a solitary cyst and 3 had multiple cysts. Sonography demonstrated internal echoes and/or lack of increased through-transmission in 6 patients. Pathological analysis was available in 6 cases and indicated a benign, hemorrhagic renal cyst. This hyperdense CT appearance is characteristic of some hemorrhagic renal cysts, though differentiation between benign and malignant cysts requires cyst puncture and/or surgery.

    Hydatid cysts are not endemic in Malaysia and are rarely seen. We hereby report a case of hydatid cyst of the liver in a 55-year-old Chinese-Australian lady who presented with a calcified liver cyst and negative hydatid serology. A liver segmentectomy was performed and revealed a well-circumscribed, calcified liver cyst containing only creamy whitish material without the typical daughter cyst. A histological examination revealed different layers of the cyst wall and the presence of loose, calcified scolices without a daughter cyst. The case highlights the importance of considering hydatid cyst in the differential diagnosis of liver cyst even in non-endemic areas, as the ease of travelling and migration allows the condition to be seen outside the endemic region.

    2000-06-01

    Longitudinal record of a case of multiple impacted teeth associated with large follicular cyst in the right maxilla was presented. The patient was an 8-year-10-month-old girl whose chief complaint was delayed eruption of the right upper incisor. Clinical examination revealed a large follicular cyst in the right maxillary sinus, which greatly displaced teeth germs. Marsupialization followed by orthodontic extrusion successfully brought unerupted teeth into their positions. Greatly displaced upper right canine, which was as high as the floor of the orbit, erupted spontaneously after reduction of the lesion. During the subsequent years, the patient developed crowded dentition and reduced overbite, which needed additional orthodontic treatment with extraction of premolars. The patient was 26-years 8-months old upon completion of treatment. The surgical, orthodontic, and periodontological aspects of the case were reexamined. Marsupialization of dentigerous cysts can preserve impacted teeth, however, the outcome might be affected by several factors such as overall growth of facial bones. PMID:10921246

    We present a case of isolated calyx that was mistaken for a large cyst. A 47-year-old woman was referred for sclerotherapy of a large cystic lesion on her left kidney. Computed tomography (CT) and ultrasound showed that the cystic lesion was a large cyst. We noticed that the cystic lesion was not a typical simple cyst, even after two sessions of catheter-mediated sclerotherapy. Isolated calyx was presumed by medical history review and was confirmed by aspirated fluid analysis and far delayed-phase CT after intravenous contrast injection. We performed meticulous selective arterial embolization for an isolated calyx and inserted a catheter that could be removed without complication.

    The benefits and risks of surgery for splenic hydatid cyst (SHC) remain controversial. We aimed to share our experience about a surgical approach for SHC. Sixteen consecutive patients with SHC disease who underwent open splenectomy at our hospital between January 2006 and July 2012 were retrospectively evaluated. Data on the patients' demographic features, clinical findings, radiological and serological diagnostic methods, and surgical and medicinal treatment options were collected and used to generate descriptive profiles of diagnosis, treatment course, and outcome. The patient population was composed of 6 females and 10 males, with an age range of 18 to 79 years (mean age: 47.0 ± 18.0). Radiological examinations detected hydatid cysts in spleen alone (n = 7) or both spleen and liver (n = 9). Preoperative serological testing identified 13 of the patients as IHA positive. All except 1 patient received a 10- to 21-day preoperative course of albendazole therapy and all patients received vaccination 1 week prior to surgery. Seven patients underwent splenectomy. The remaining patients underwent splenectomy with partial cystectomy and omentopexy (n = 6), partial cystectomy and unroofing (n = 1), pericystectomy (n = 1), or pericystectomy with partial nephrectomy (n = 1). All except one patient received a 10- to 45-day postoperative course of albendazole. No patients developed serious complications or signs of recurrence during the follow-up. The clinical profile of SHC disease at our hospital includes diagnosis by radiological methods, splenectomy treatment by simple or concomitant procedures according to the patient's symptoms, cyst size, number and localization, and compression of adjacent organs, and adjunct vaccination to decrease risk of postoperative septic complications. This profile is associated with low risk of complications and high therapeutic efficacy. PMID:24229022

    As dentigerous cysts increase in size, the risk of postsurgical complications increases as well. Emphasis is usually placed on the risk of neurologic damage caused by trauma during and after surgical removal and of mandibular fracture resulting from the large residual bone defect. However, influence on the periodontal status of neighbouring teeth should also be taken into account. In this article, we present an interdisciplinary, safe, minimally invasive approach to treating large dentigerous cysts associated with deeply impacted third molars. A dentigerous cyst is an epithelial-lined pathologic cavity that develops in association with the crown of an unerupted tooth and appears radiographically as a well-circumscribed pericoronal radiolucency. The cyst not only inhibits the eruption of the associated tooth (usually, a mandibular third molar), but can also carry it to unusual positions in the jaw. Dentigerous cysts may enlarge causing extensive bone resorption and even pathologic fracture. The greater the size of the cyst, the higher the risk of neurologic damage caused by trauma during and after surgical removal and of mandibular fracture resulting from the postoperative bone defect.7,8 Moreover, the removal of large cysts can lead to a severe infrabony defect at the root surface of adjacent teeth, jeopardizing their long-term periodontal health. "Orthodontic extraction" is a combined orthodontic-surgical approach that decreases the risk of neurologic complications and facilitates the surgical extraction of impacted mandibular third molars that are in close contact with the mandibular canal, even when associated with cystic lesions.13 This case report shows that the interdisciplinary approach is also effective in preventing periodontal breakdown on the distal surface of the adjacent second molar.

    Objective The objectives of this study were to investigate the relationship between the segmental localization of liver hydatid cyst by computed tomography (CT) and the presence of cystobiliary communication (CBC) and to identify the risk factors for CBC. Patients and methods One hundred and eleven of 163 patients who underwent liver hydatid surgery between January 2011 and September 2014 were included in this study and analyzed retrospectively. The size, number, stage, and segmental and lobar localization of the cysts were investigated by CT. The presence of CBC and preoperative laboratory findings were recorded from operation notes. Results CBC was more frequent in single large cysts. CBC was most commonly detected in segment 1 (50%), 8 (48.3%), 7 (41.2%), and 4 (40%). CBC was more frequent in the right lobe (40.4%) and Gharbi stage 3 (41.8%) and 4 (55.6%) lesions. There were no differences in CBC according to distance from the hilus. In addition, preoperative total bilirubin, direct bilirubin, alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) elevations were associated with higher CBC frequency (P<0.05). Cyst diameter, number of cysts, and ALP and GGT elevations were independent predictors of CBC presence. Conclusion The evaluation of hydatid cyst diameter, morphological stage, and segmental and lobar localization by abdominal CT and measurement of preoperative cyst diameter, number of cysts, and ALP and GGT values may predict the presence of CBC.

    Synovial cysts at the atlantoaxial level are found uncommonly. Lumbar symptomatic cases are treated by percutaneous cyst aspiration with or without corticoid injection or by surgical resection, but synovial cysts at the C1-C2 level are usually treated by surgery. We report here a 92-year-old woman with a retro-odontoid synovial cyst producing spinal cord compression that was treated by percutaneous aspiration of the cyst under CT guidance. To our knowledge, this is the first reported case of an atlantoaxial synovial cyst successfully treated with a minimally invasive procedure.

    Within the past few decades, there has been a dramatic increase in the detection of incidental pancreatic cysts. It is reported a pancreatic cyst is identified in up to 2.6% of abdominal scans. Many of these cysts, including serous cystadenomas and pseudocysts, are benign and can be monitored clinically. In contrast, mucinous cysts, which include intraductal papillary mucinous neoplasms and mucinous cystic neoplasms, have the potential to progress to pancreatic adenocarcinoma. In this review, we discuss the current management guidelines for pancreatic cysts, their underlying genetics, and the integration of molecular testing in cyst classification and prognostication.

    2015-01-01

    Introduction: Intra-articular ganglion cysts of the knee joint are rare occurrences. They are usually encountered as incidental findings in magnetic resonance imaging (MRI), or in arthroscopy. They may originate from both the cruciate ligaments and the menisci, from the popliteus tendon and alar folds, infrapatellar fat pad of Hoffa, and subchondral bone cysts. Those arising from the Hoffa’s fat pad, usually present as palpable mass at anterior aspect of the knee joint. We report a case of intraarticular ganglion cyst of knee arising from the infrapatellar fat pad and protruding anterolaterally through retinacular rent into the subcutaneous plane. Case Report: A 19-year-old young man, presented with a painless gradually increasing swelling at the anterior aspect of left knee of 9 months duration. MRI scan revealed a multilobulated, cyst with septations within the anterior aspect of the knee joint, just inferolateral to the patella, with deep extension into the infrapatellar fat pad, and superficial extension into the subcutaneous space across the retinaculum. After diagnostic arthroscopy, we performed an open excision of the cystic mass and confirmed the retinacular rent pre-operatively. Conclusion: Arthroscopic resection and debridement is the gold standard treatment in ganglion cyst of the knee. However, a subcutaneous extension may lead to incomplete arthroscopic resection: Leaving behind the residual tissue which may cause recurrence. Therefore, proper pre-operative evaluation of MR images of these cases is very important. PMID:27299075

    Background Symptomatic sacral perineural cysts are a common cause of chronic pain. Surgery is one choice for symptom relief but has a high risk of cyst recurrence and complications. As a simple and safe method to manage symptomatic sacral perineural cysts, C-arm fluoroscopy-guided fibrin gel injection may represent a new minimally invasive alternative. To evaluate the efficacy of this new method, we conducted a retrospective study of 42 patients. Methods and Findings From June 2009 to August 2012, a total of 42 patients with symptomatic sacral perineural cysts underwent C-arm fluoroscopy-guided percutaneous fibrin gel injection therapy. Patient outcomes in terms of improvements in pain and neurologic function were evaluated during a follow-up period of 13–39 months. The preoperative and postoperative pain severity were assessed according to a 10-cm visual analog pain scale, and imaging changes were evaluated by magnetic resonance imaging. We also assessed postoperative complications. Most patients experienced benefit from the procedure: twenty-five patients (59.5%) reported excellent recovery, eleven (26.2%) reported good recovery, three (7.1%) reported fair recovery, and three (7.1%) reported poor recovery. The overall effectiveness rate (excellent and good recoveries) was 85.7%. No serious postoperative complications were observed. Conclusion Percutaneous fibrin gel injection under C-arm fluoroscopy guidance could be a simple, safe and effective treatment option for symptomatic sacral perineural cysts. PMID:25706639

    We report the case of a female patient suffering from continuous lower abdominal distending pain from an ovarian cyst for 1 year. The sonography taken on February 12, 2008 showed on the right ovary in the frontal position a cystic mass of 43.0 x 22.0 x 45.0 mm, which was found with an intact, regular, and thin membrane and a uniform echo without blood flow. The acoustic density of the sac fluid was transparent. Pelvic fluid collection with a depth of 10 mm existed as a liquid dark area around the uterus. A simple formula of Chinese herbs, Penyan Kang (formula for treating pelvic inflammation), was orally administered to the patient for 90 days. On the 6th return visit on May 10, 2008, the patient said that all the symptoms reported during the first visit had disappeared. The sonography taken on May 27, 2008 showed that the ovarian cyst on the right side had disappeared and that no abnormality was present. No side-effect of the treatment was reported. PMID:19887813

    Objective To investigate which structural MR abnormalities discriminate symptomatic knee osteoarthritis (OA), taking co-occurrence of abnormalities in all compartments into account. Methods The Netherlands Epidemiology of Obesity (NEO) study is a population-based cohort aged 45–65 years. In 1285 participants (median age 56 years, 55% women, median body mass index (BMI) 30 kg/m2), MRI of the right knee were obtained. Structural abnormalities (osteophytes, cartilage loss, bone marrow lesions (BMLs), subchondral cysts, meniscal abnormalities, effusion, Baker's cyst) at 9 patellofemoral and tibiofemoral locations were scored following the knee OA scoring system. Symptomatic OA in the imaged knee was defined following the American College of Rheumatology criteria. Logistic ridge regression analyses were used to investigate which structural abnormalities discriminate best between individuals with and without symptomatic OA, crude and adjusted for age, sex and BMI. Results Symptomatic knee OA was present in 177 individuals. Structural MR abnormalities were highly frequent both in individuals with OA and in those without. Baker's cysts showed the highest adjusted regression coefficient (0.293) for presence of symptomatic OA, followed by osteophytes and BMLs in the medial tibiofemoral compartment (0.185–0.279), osteophytes in the medial trochlear facet (0.262) and effusion (0.197). Conclusions Baker's cysts discriminate best between individuals with and without symptomatic knee OA. Structural MR abnormalities, especially in the medial side of the tibiofemoral joint and effusion, add further in discriminating symptomatic OA. Baker's cysts may present as a target for treatment.

    Scanning is based on the uptake of a nuclide by the crystal lattice of bone and is related to bone blood flow. Cancer cells do not take up the tracer. Normally, the scan visualizes the highly vascular bones. Scans are useful and are indicated in metastatic bone disease, primary bone tumors, hematologic malignancies and some non-neoplastic diseases. The scan is more sensitive than x-ray in the detection of malignant diseases of the skeleton. PMID:1054210

    A qualitative and semi-quantitative study of recent dinoflagellate cysts has been undertaken in the NW part of Aegean Sea, Thermaikos Gulf (Eastern Mediteranean), before (September 2001), during (October 2001) and after 120 days (February 2002) of intensive trawling activities. This is the first survey of recent dinoflagellate cysts from Greek marine coastal environments. Sediment samples were collected with a corer and the vertical distribution of the cysts was studied at five different layers, from 0 to 10 cm. Dinoflagellate cysts were both abundant and diverse. Cysts were found over the whole sampling area and periods, with concentrations ranging between 247-3202 cysts cm -3. Thirty-six cyst types were encountered, of which 32 were identified to species level, representing 12 genera. It seems that significant local resuspension, related to the onset of the trawling period and stirring up of the sediment, contributed to mixing of the upper layers, resulting to more homogenous cyst profiles in the sediment. Viable cysts constituted 16-60% of the total cyst abundance. The abundance peaks of viable cysts within the subsurface sediment layers, observed during the undisturbed period, disappeared during October. In February, the reduction of cyst concentration was associated to a loss of viable cysts, whilst the ratio of viable/empty cysts ranged between 0.30 and 0.67. The abundance of the different dinoflagellate species, in their active form, was monitored in order to detect any relationship between the concentration of cysts in the top 10 cm of sediment and blooms of algae in the water column. Cysts of potentially toxic species, causing Paralitic Shellfish Poisoning (PSP), such as Alexandrium cf. tamarense, A. cf. affine, A. cf. minutum, as well as Gymnodinium catenatum, were detected in the cyst survey.

    Retro-rectal cystic hamartoma (tailgut cyst), is an uncommon congenital developmental lesion, generally located in the retro-rectal space. Its diagnosis and approach is challenging because the retropelvic space is not familiar. We report a 51-year-old woman who presented with paresthesia and pain in perianal area. The magnetic resonance image showed high signal intensity on the T1-weighted image and iso to high signal intensity on the T2-weighted image of the retropelvic space and CT showed sacral bony defect. We chose the posterior approach for removal of the tailgut cyst. Histopathology exam of the retropelvic cyst revealed a multiloculated cyst containing abundant mucoid material lined by both squamous and glandular mucinous epithelium. The patient has recovered nicely with no recurrence. Tailgut cyst needs complete surgical excision for good prognosis. So, a preoperative high-resolution image and co-operation between neurosurgen and general surgeon would help to make safe and feasible diagnosis and surgical access. PMID:27073796

    Introduction: The hydatid cyst is a real public health problem in Tunisia. The retrovesical localization is rare. It is considered an aberrant or ectopic location defined by the development of the parasite in the subvesical and retrovesical fat. Methods: From 2004 to 2013, 4 patients with retrovesical hydatid cyst were hospitalized and operated in the Department of Urology at the Charles Nicolle hospital of Tunis in Tunisia. The average patient age was 40.75 years (range: 23–76). Signs of bladder irritation were the most frequent presenting complaint. No cases of hydaturia were noted. The diagnosis was made on the ultrasound and the computed tomographic urography. Hydatid serology was positive for 3 patients. In 3 cases, a hydatid cyst of the liver was associated. A total cysto-pericystectomy was performed for 1 patient, for others it was partial. Results: The postoperative course was uneventful. No urinary fistula or infection of the residual cavity was observed. One patient had a retroperitoneal cyst recurrence requiring reoperation. Conclusion: Retrovesical location of hydatid cyst is rare and treatment is primarily surgical. PMID:26225181

    Increased breast cancer risks have been reported among women with gross cystic breast disease (GCBD), although the mechanism for this increase remains unexplained. Relationships between GCBD characteristics, breast cancer risk factors, and the biochemical composition and growth properties of 142 breast cyst fluid (BCF) samples were studied among 93 women with GCBD. Concentrations of melatonin, estrogen (17-beta-estradiol), dehydroepiandrosterone-sulfate (DHEA-S), epidermal growth factor (EGF), transforming growth factor beta (TGF-B1 and TGF-B2), sodium (Na), and potassium (K) were quantified in BCF samples, and human breast cancer cells (MCF-7) were treated with BCF in vitro. Patients were grouped according to BCF Na:K ratios previously linked with increased breast cancer risks (Na:K 3, Type 2) and mixed cyst groups. Women with larger and more frequently occurring cysts had higher BCF estrogen and DHEA-S, and lower TGF-B1 levels. Women with Type 1 cysts had elevated BCF melatonin, estrogen, DHEA-S, and EGF, and lower concentrations of TGF-B2 compared to women with Type 2 cysts. BCF generally inhibited cell growth relative to serum-treated controls, consistent with previous studies. Melatonin and estrogen in BCF independently predicted growth inhibition and stimulation, respectively. Biological monitoring of BCF may help identify women with GCBD at greatest risk for breast cancer development. PMID:17061046

    A cystic lesion adjacent to the dens with compression of the lower portion of the medulla oblongata was found on MRI in a 75-year-old male patient with a 2-month history of occipital pain and gait disturbance. Clinically, the patient showed mild tetraparesis, signs of spinal ataxia and symmetrical hyperreflexia. Following subtotal removal of the cyst via left-sided suboccipital craniotomy and left-sided hemilaminectomy of C1 the lesion was classified as synovial cyst on histopathological examination. Postoperatively, the quadriparesis almost completely subsided and the patient is currently doing well, 33 months after surgery. Synovial or ganglion cysts adjacent to the atlantoaxial articulation with ventral compression of the cervicomedullar cord represent rare surgical or radiological entities. Atlantoaxial synovial cysts have no typical radiographic appearance or specific neurological symptoms so that they are frequently misdiagnosed as intraspinal- or skull base tumour, rheumatoid lesion or ectatic vertebral artery. Since no ensuing complications or recurrences have been encountered in cases of incompletely removed cysts the less invasive operative approaches should be used to avoid destabilisation and subsequent additional surgical procedures.

    The approach to incidentally noted pancreatic cysts is constantly evolving. While surgical resection is indicated for malignant or higher risk cysts, correctly identifying these highest risk pancreatic cystic lesions remains difficult. Using parameters including cyst size, presence of solid components, and pancreatic duct involvement, the 2012 International Association of Pancreatology (IAP) and the 2015 American Gastroenterological Association (AGA) guidelines have sought to identify the higher risk patients who would benefit from further evaluation using endoscopic ultrasound (EUS). Not only can EUS help further assess the presence of solid component and nodules, but also fine needle aspiration of cyst fluid aids in diagnosis by obtaining cellular, molecular, and genetic data. The impact of new endoscopic innovations with novel methods of direct visualization including confocal endomicroscopy require further validation. This review also highlights the differences between the 2012 IAP and 2015 AGA guidelines, which include the thresholds for sending patients for EUS and surgery and methods, interval, and duration of surveillance for unresected cysts.

    ABSTRACT Dentigerous Cyst/developmental cyst of benign odontogenic origin are ones that surround the crown of impacted, embedded, unerupted or developing teeth. Dentigerous cyst is second most common cyst of the oral cavity after radicular cyst. They are usually solitary in occurrence and mostly associated with the mandibular third molars. Dentigerous cysts involving impacted second premolars are rarely reported in the literatures. We present a rare case of dentigerous cyst in a 12-year-old female patient associated with an impacted mandibular second premolar. How to cite this article: Mishra R, Tripathi AM, Rathore M.

    We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts) are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints. PMID:21139800
