The unusual evolution of a simple bone cyst in the mandible: A case report  

PubMed Central

The simple bone cyst, as newly classified by WHO in 2005, is a lesion related to the jawbones. Therefore, it is not a cyst, since it is a cavity devoid of epithelial tissue. It is a rare pathology affecting the mandible more than the maxilla. Its onset occurs mainly during the first two decades of life, irrespective of sex. The purpose of our report is to exhibit the particular case of a 17-year-old male patient whose radiography showed an osteolytic lesion in his right mandibular body. Exploratory surgery and biopsy are performed showing a simple bone cyst. Since then, he is controlled through imaging studies, but presenting an atypical evolution, with its size increasing considerably within a 4-year follow-up. Key words:Case report, simple bone cyst, hemorrhagic bone cyst, solitary bone cyst, idiophatic bone cyst, mandible. PMID:24558539

[Large simple liver cyst treated laparoscopically].  

PubMed

Simple liver cysts of various sizes are present in 1% of the population. Most are found incidentally and require no treatment. However, in a few the cyst is symptomatic and requires surgery: celiotomy and unroofing of the cyst. A 64-year-old woman with a symptomatic, simple cyst of the liver underwent laparoscopic surgery. After an uneventful course she was discharged on the 3rd postoperative day. Simple liver cysts can be safely treated by laparoscopic surgery. PMID:8138207

Relationship of Simple Renal Cyst to Hypertension  

PubMed Central

Background Simple renal cyst is the most common cystic deformation found in adults. However, there were a few systematic Korean reports for the clinical symptoms and complications of simple renal cysts. The author's purpose was to determine the relationship between simple renal cysts diagnosed by abdominal ultrasonography and hypertension. Methods Among 13,482 persons who took a routine physical examination at Ulsan University Hospital in 2002, 5,127 persons who took medical examinations again in 2010 were selected. We excluded persons who had renal cyst, hypertension, diabetes, liver cirrhosis, kidney disease, thyroid disease, and cancer in 2002. Analysis was conducted for 505 subjects with newly diagnosed simple renal cyst and 2,744 subjects without renal cyst in 2010. The simple renal cyst group was compared to a control group without renal cyst. Results Among 3,249 subjects, simple renal cyst and hypertension were newly diagnosed in 505 subjects and 503 subjects. The subjects who had simple renal cysts had significantly higher hypertension incidence (odds ratio [OR], 1.53; 95% confidence interval [CI], 1.20 to 1.94). Significant hypertension incidence was observed especially when the subjects had cysts located on both kidneys (OR, 3.48; 95% CI, 2.12 to 5.71), two (OR, 3.08; 95% CI, 1.84 to 5.15) or more cysts (OR, 3.12; 95% CI, 1.38 to 7.04), and larger cysts more than 1 cm in diameter (OR, 1.55; 95% CI, 1.16 to 2.07). Conclusion The presence of simple renal cysts was significantly positively related to the incidence of hypertension. Bilateral distribution, two or more number, and larger size than 1 cm diameter were the characteristics of simple renal cyst related to hypertension. PMID:25309704

Unicameral bone cyst of the lunate in an adult: case report  

PubMed Central

We report a case of a symptomatic unicameral (simple) bone cyst of the lunate in a 42-year- old woman. The lesion was treated with curettage and cancellous autogenous iliac bone grafting. At five years of follow-up the wrist was pain free, there were no limitations of motion, and the radiographs showed complete obliteration of the cavity. To the best of our knowledge, no other unicameral bone cyst of the lunate has been reported in an adult. Cysts with significant cavities at the carpal bones in an adult should be approached cautiously, as they may require early curettage and bone grafting for healing, before collapse and degenerative changes occur.

Introduction An aneurysmal bone cyst is a benign, but expansile tumor like lesion that generally occurs in the long bones including the vertebral column. An aneurysmal bone cyst arising from the rib, especially in the elderly, is extremely rare. Case presentation We report a 58-year-old Turkish woman with an aneurysmal bone cyst of the right 3rd rib treated with chest wall resection. The pathologic findings confirmed the diagnosis of aneurysmal bone cyst. The patient has been followed up for 5 years with no evidence of recurrence. Conclusion En bloc resection can be curative and provide good results for this rare type of chest wall tumor. PMID:19918277

Subperiosteal resection of fibular aneurysmal bone cyst.  

PubMed

Aneurysmal bone cyst (ABC) of the fibula poses a challenge as to the most appropriate treatment particularly in children and adolescents. A prospective study was conducted to evaluate the results of subperiosteal resection of fibular ABCs. Eleven patients (six boys and five girls) with an average age of 12.4 years (6-18 years) were treated by subperiosteal resection of ABC of the fibula. The lesion was juxtaphyseal in three patients (two distal and one proximal), metaphyseal in seven and diaphyseal in one. All cysts were active and centrally located type 2. The modified Enneking scoring system was used for final functional evaluation while a scale proposed by the author was used for final radiological assessment. At the final follow-up, there was no difference in the range of movement, alignment or stability of the ankle or the knee when compared with the opposite side. Three patients complained of mild discomfort on heavy activity. One patient had failure of healing that was related to the use of suction drain. After a mean follow-up of 41.6 months (24-64 months), the mean functional score was 98.8 % (93-100 %). According to the proposed radiological scale, six patients were rated excellent, three good, one fair and one poor. In conclusion, subperiosteal resection is effective in eradicating fibular ABCs, regenerates a new bone and avoids the morbidity of other techniques. PMID:25205471

Aneurysmal Bone Cysts of the Spine: Two Case Reports  

PubMed Central

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fractures occur, neurological findings can be seen and the surgical treatment, if needed, could be difficult. We will discuss our evaluations to two cases that we experienced in our clinic in this report.

Conservative and radiological management of simple renal cysts: a comprehensive review.  

PubMed

What's known on the subject? and What does the study add? Simple renal cysts are a common entity, which may need observation and follow-up or treatment. The study, for the first time, systematically reviews the indications for follow-up or radiological treatment of simple renal cysts. To review the conservative and radiological management of simple renal cysts a systematic literature review was performed. Simple renal cysts are commonly found in the adult population. Increasing age is highly associated with its incidence. When they remain asymptomatic they require neither treatment nor follow-up. When the shape of the cyst is slightly irregular follow-up is mandatory to exclude malignant progression. Symptomatic cysts require intervention. Ultrasound or computed tomography guidance have been effectively used for cyst puncture. However, simple fluid aspiration is ineffective leading to cyst recurrence. Aspiration should be accompanied with the injection of a sclerosing agent to destroy renal cyst epithelium. Several issues such as the ultimate technique and agent remain to be clarified. High rates of cyst disappearance and long-lasting cyst volume reduction have been reported with the use of various sclerosants. Ethanol in high concentrations and multiple injections is more commonly used with new agents showing similar efficacy and better complication profile. Studies comparing radiological intervention to surgical excision are lacking. Simple renal cysts may not require treatment when asymptomatic. Radiological intervention with the use of sclerosants needs further evaluation and comparison with other treatment methods. PMID:22414207

Multiple painful bone cysts in a young man.  

PubMed Central

To confirm the diagnosis of diffuse cystic angiomatosis, it is necessary to biopsy the bone: the walls of the cysts react to immunological markers of the endothelium (antigens related to factor VIII and CD31). Alternatively, lymphography can avoid the necessity for biopsy. Evolution of the condition is variable and depends on the extent of visceral involvement, and usually the extent of soft tissue and visceral involvement dictates the morbidity and mortality. There is no specific treatment, though osseous lesions can regress spontaneously. Images PMID:8694572

A giant aneurysmal bone cyst of the rib: Case report  

PubMed Central

An aneurysmal bone cyst (ABC) is a benign tumor of the skeletal system, which most frequently occurs in long bones. An ABC arising from the rib is extremely rare and it is difficult to distinguish from other types of rib tumors. The present study describes an unusual case of a large ABC in the rib of a 17-year-old male. The entity is discussed with particular emphasis on the clinicopathological features, differential diagnosis and treatment. Due to difficulties in the pre-operative diagnosis, a possible diagnosis of ABC should be made aware when confronting an expansile rib mass. An en bloc resection of the mass and the affected portion of the rib is mandatory to obtain a satisfactory outcome. PMID:24348861

Sclerotherapy with polidocanol for treatment of aneurysmal bone cysts  

PubMed Central

Background and purpose Recent data suggest that percutaneous sclerotherapy is a safe alternative to surgery for treatment of aneurysmal bone cysts (ABCs). We present our experience of this method. Methods We retrospectively analyzed data from 38 consecutive patients treated with repeated injections of polidocanol. Each injection consisted of 2–4 mg polidocanol per kg body weight. Radiological and clinical assessments were performed until healing. Results All cycts except 1 healed after a median of 4 (1–11) injections. A lesion failed to heal in 1 patient, who was operated. 3 patients experienced minor local inflammatory reactions. Interpretation Our results show that percutaneus sclerotherapy with polidocanol has high efficacy in the treatment of ABCs, with a low frequency of side effects. Our findings corroborate data presented in previous publications. We believe that the method will be especially valuable in ABCs of the pelvis and sacrum, where surgery is associated with considerable morbidity. PMID:24171682

Endoscopic Surgery for Symptomatic Unicameral Bone Cyst of the Proximal Femur  

PubMed Central

Recently, surgical treatment of a symptomatic unicameral cyst of the proximal femur has been achieved with less invasive procedures than traditional open curettage with an autologous bone graft. In this article we introduce endoscopic surgery for a symptomatic unicameral cyst of the proximal femur. The presented technique, which includes minimally invasive endoscopic curettage of the cyst and injection of a bone substitute, not only minimizes muscle damage around the femur but also enables sufficient curettage of the fibrous membrane in the cyst wall and the bony septum through direct detailed visualization by an endoscope. Furthermore, sufficient initial strength after curettage can be obtained by injecting calcium phosphate cement as a bone substitute. PMID:24892010

Aneurysmal bone cyst is a benign pseudocystic osseous lesion characterized by a fibrous connective tissue stroma with cellular fibrous tissue, multinucleated giant cells, and large blood-filled spaces with no endothelial lining. The entity is uncommon in facial bones, and it rarely involves the mandibular condyle. Resection of the lesion is the most accepted treatment. The present case is the 11th reported case of aneurysmal bone cyst of the mandibular condyle in the existing literature and the first where, rather than using conventional extra oral approach, sagittal split ramus osteotomy was used to excise the lesion successfully with no recurrence after 3 years of follow-up.

Giant cell tumor (GCT) is a distinctive lesion characterized by the proliferation of multinucleate giant cells in a stroma of mononuclear cells; it is generally seen in skeletally mature individuals. GCT of bone is usually found in the long bones around the knee or in the distal radius of young adults and is unusual in the flat bones. We report a case of GCT of the acromion of the scapula, with a secondary aneurysmal bone cyst, in a 30-year-old female. Based on our review of the English language medical literature, it appears that the occurrence of a GCT along with a secondary aneurysmal bone cyst in flat bones (e.g.. the scapula) is very rare.

Large symptomatic simple hepatic cyst with gastric compression treated with percutaneous drainage.  

PubMed

Nonparasitic hepatic cysts consist of a heterogeneous group of disorders, which differ in etiology, prevalence, and manifestations. Simple hepatic cysts are considered nonparasitic ones. These are a result of congenital anomalies of the biliary system, and these may be single or multiple. Generally, hepatic cysts are incidentally found during occasional laparotomy or laparoscopy, necropsy, and even during routine ultrasound or computerized tomography (CT) scan. Nowadays, with improving diagnostic techniques, hepatic cysts are becoming more common. Generally these lesions are asymptomatic. However, if they grow, they may become symptomatic. Symptoms depend on the size and location. When symptoms developed, these must be treated. Compressive complications due to local "liver mass" effect include: portal hypertension, edema due to caval compression, jaundice and arrhythmia and duodenal obstruction. Gastric extrinsic compression by liver cysts has been poorly described. Herein, we present a case of a female in whom percutaneous drainage of a large simple hepatic cysts not complicated was performed in order to reduce signs of gastric compression. PMID:24770829

Simple testicular cyst: a rare cause of scrotal swelling in infancy.  

PubMed

A simple testicular cyst is a rare cause of scrotal swelling in infancy. Only 10 cases have been reported in children less than two years of age in the English literature. Pathogenesis of the lesion is unclear. Preoperative diagnosis is possible using ultrasonography (US). Testis-sparing surgery with simple enucleation of the cyst has a favorable outcome. We report two patients with a simple testicular cyst, who were 9 and 8 months of age. The first case was referred with a presumptive diagnosis of hydrocele, and the second infant was admitted with a history of testicular swelling. Ultrasonography provided accurate preoperative diagnosis in both of the cases. The patients were successfully treated with testis-sparing surgery with outstanding long-term results. This unusual lesion of infancy should be considered in the differential diagnosis of a scrotal mass. PMID:15147558

Aneurysmal bone cysts are not counted among the classic malignant tumors, although they are destructive locally as blood filled reactive bone lesions. Typically, they are found in the metaphysis of the long bones, while localizations on the spine are rare. A 16-year-old female patient presented with unspecific, progressive neck pain which had been present for half a year. The initial x-ray showed no noticeable pathology whatsoever. Subsequently, the complete destruction of the first cervical vertebrae was found. The tumor had completely infiltrated and completely surrounded the spinal chord. A combined approach was used as therapy: resection of the dorsal tumor portion with occipitocervical spondylodesis (C0-C4) and postoperative radiation of the remaining ventral portions. Currently, the patient is free of complaints and recurrence. The differential diagnosis of an aneurysmal bone cyst should also be considered in cases of unspecific cervical vertebral complaints in adolescents that are not otherwise explainable. PMID:17431575

Bone Cysts After Osteochondral Allograft Repair of Cartilage Defects in Goats Suggest Abnormal Interaction Between Subchondral Bone and Overlying Synovial Joint Tissues  

PubMed Central

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 ?CT 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. These findings suggest that cysts occurring after OCA may result from aberrant mechanobiology due to (1) altered compartmentalization that normally separates overlying cartilage and subchondral bone, either from distinct ScB channels or more general ScB plate deterioration, and (2) bone resorption at the basal graft-host interface.

Clinical factors affecting pathological fracture and healing of unicameral bone cysts  

PubMed Central

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.

Magnetic resonance imaging revealed a large multilocular cystic mass with canal invasion and bone erosion confined to left S1 body. The lesion showed multiple septal enhancement without definite solid component. Initially the tumor was considered as ABC. The patient underwent grossly-total tumor resection with lumbosacral reconstruction via posterior approach. The tumor was proved to be a cystic schwannoma. The postoperative course was uneventful and the patient was relieved from preoperative symptoms. We present a rare case of pure cystic giant schwannoma confined to sacrum mimicking ABC. The surgical treatment is challenging due to the complex anatomy of the sacrum. Schwannoma should be considered in the differential diagnosis of osteolytic sacral cysts. PMID:24294462

Spontaneous regression after extensive recurrence of a pediatric cervical spine aneurysmal bone cyst.  

PubMed

Aneurysmal bone cyst is a pseudotumoral lesion. Complete resection prior to selective arterial embolization seems to be the treatment of choice for the more extensive and destructive lesions. In these cases maintaining stability of the cervical spine is critical. This can be very challenging in children and adolescents in whom the axial skeleton is still growing. In this case a young girl presented with a voluminous cervical aneurysmal bone cyst encaging both vertebral arteries and spinal cord. The lesion was treated with aggressive surgical resection, followed by cervical vertebral fusion with instrumentation. After nine months the patient referred no pain and no neurological deficit. MRI scans showed an extensive local recurrence. The family of the young girl refused any other therapy and any other followup. The patients returned to our attention after five years with no pain and neurological deficit. Cervical spine radiographs and MRI scans showed a complete regression of the extensive local recurrence. In the literature, the possibility of spontaneous regression of residual part or local recurrence is reported. The case of this young girl provided the chance to attend a spontaneous regression in an extensive recurrence of aneurismal bone cyst. PMID:24707421

The association between subchondral bone cysts and tibial cartilage volume and risk of joint replacement in people with knee osteoarthritis: a longitudinal study  

PubMed Central

Introduction To examine the natural history of subchondral bone cysts and to determine whether knee cartilage loss and risk of joint replacement is higher in knees with cysts, compared with those with bone marrow lesions (BMLs) only or those with neither BMLs nor cysts. Methods The symptomatic knee in 132 subjects with knee osteoarthritis (OA) was imaged by using magnetic resonance imaging at baseline and 2 years later. Tibial cartilage volume, subchondral bone cysts, and BMLs were measured by using validated methods. Knee arthroplasty over a 4-year period was ascertained. Results Bone cysts were present in 47.7% of subjects, 98.1% of whom also had BMLs. Over a 2-year period, 23.9% of subjects had cysts progress, 13.0% developed new cysts, and 11.4% had cysts regress. Bone cysts at baseline were associated with lower medial and lateral tibial cartilage volume compared with those with BMLs only or those with neither (P for trend 0.004 and <0.001, respectively). Annual medial cartilage volume loss was greatest in those with bone cysts compared with those with BMLs only or those with neither (9.3%, 6.3%, and 2.6%, respectively; P for trend, <0.001). As the severity of bone abnormality in the medial compartment increased from no BMLs or cysts present, to BMLs only, to subchondral bone cysts present, the risk of knee replacement was increased (odds ratio, 1.99; 95% confidence interval (CI), 1.01 to 3.90; P = 0.05). Conclusions When cysts are present, cartilage loss and risk of knee replacement are higher than if only BMLs are present, suggesting that cysts identify those most likely to benefit from prevention of disease progression. As cysts can regress, they may also provide therapeutic targets in knee OA. PMID:20356405

Percutaneous treatment of symptomatic aneurysmal bone cyst of L5 by percutaneous injection of osteoconductive material (Cerament).  

PubMed

We present a case report of a 33-year-old woman with back pain for several months which was resistant to medical treatment. Thoracolumbar MRI and multidetector CT showed an aneurysmal bone cyst intersecting the body and pedicles of L5. Minimally invasive treatment was performed with percutaneous injection of osteoconductive cement (Cerament) to induce sclerosis and bone remodeling of the bone cyst lesion with an analgesic effect. Before treatment, spinal angiography was performed to exclude arterial afferents. No bone biopsy was done. Under general anesthesia and fluoroscopic guidance, a first vertebroplasty was performed by a bilateral transpedicular approach using the osteoconductive cement followed 2 months later by a second treatment with CT-fluoro-guided direct injection of Cerament. No complications occurred during the procedure. At 4 and 6 months follow-up the MRI/CT showed sclerotic bone remodeling of the walls of the aneurysmal cyst with clinical improvement. PMID:24186854

Ultrasonic bone-cutting surgery has been introduced as a feasible alternative to the conventional sharp instruments used in craniomaxillofacial surgery because of its precision and safety. The device used is unique in that the cutting action occurs when the tool is used on mineralized tissues and stops on soft tissues. This work describes the use of piezosurgery for hyoid bone resection in thyroglossal duct cyst surgery, briefly reviews the literature on the surgical technique, and reports our experience with 12 cases.

Secondary brain abscess following simple renal cyst infection: a case report  

PubMed Central

Background Escherichia coli (E. coli) is the most common causative bacteria of neonatal meningitis, but hematogenous intracranial E. coli infection is rare in adults. Moreover, intracranial abscess formation owing to E. coli, including brain abscesses and subdural empyema formation, is extremely rare. We herein present a case involving a patient with a brain abscess owing to E. coli following a simple renal cyst infection. A review of the literature is also presented. Case presentation A 77-year-old Japanese woman with a history of polymyalgia rheumatica was admitted to our hospital because of persistent fever, right flank pain, and pyuria. Intravenous antibiotics were administered; however, her level of consciousness deteriorated 6 days after admission. Contrast-enhanced magnetic resonance imaging showed a brain abscess in the left occipital lobe and pyogenic ventriculitis. Enhanced abdominal computed tomography revealed a right renal cyst with heterogeneous content. Culture of urine, blood, and aspirated pus from the infected cyst revealed E. coli with identical antibiotic sensitivity in all sites, suggesting that the cyst infection and subsequent bacteremia might have caused the brain abscess. The patient recovered after a 6-week course of meropenem. Conclusion The prognosis of patients with E. coli-associated intracranial abscess is usually poor. Advanced age and immunosuppression may be potent risk factors for intracranial abscess formation owing to the hematogenous spread of E. coli. PMID:24934996

Aneurysmal Bone Cyst Presenting as a Pathologic Fracture in a 12-Year-Old Football Player  

PubMed Central

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

Juvenile psammomatoid ossifying fibroma with aneurysmal bone cyst in the posterior mandible  

PubMed Central

Aneurysmal bone cysts (ABCs) are a rare benign lesion seen as locally destructive, rapidly expansile, and mostly affecting the long bones and vertebrae. The association of ABCs with juvenile psammomatoid ossifying fibroma (PsJOF) is predominantly seen in the extragnathic region, and it is extremely rare with only a few cases reported so far in the mandible. Here, we report one such case of a hybrid lesion in a seven-year-old boy, who presented with a solitary swelling of the left mandible showing partial obliteration of buccal vestibular sulcus, which shows juvenile psammomatoid ossifying fibroma as a pre-exsiting lesion, transforming into an ABC. Such hybrid lesions are usually misdiagnosed and have been sparsely reported in the dental literature. PMID:25374619

Continuous decompression with intramedullary nailing for the treatment of unicameral bone cysts  

PubMed Central

Purpose To evaluate the efficacy of decompression of unicameral bone cysts (UBCs) of the long bones with intramedullary nailing and to compare responses to treatment according to location. Materials and methods We evaluated 48 consecutive patients treated between January 1988 and June 2000. Mean age was 10.3 years. Mean follow-up was 9.8 years. Evaluation was performed according to the radiographic criteria of Capanna. Results UBCs were located in the proximal humerus (n = 24), humeral shaft (n = 2), proximal femur (n = 19), distal tibia (n = 2) and fibula (n = 1). A total of 62.5% presented a pathological fracture. Successful results were observed in 89.5% (26 total healing, 17 healing with residual radiolucent areas), and there were four recurrences and, in one case, no response to treatment. There was more healing in the humerus than in the femur (92.3% versus 84.2%), and more tendency to restitution ad integrum, although the difference was not statistically significant (P = 0.1499). Conclusions Intramedullary nailing is a minimally invasive method, which permits early stability and decompresses the cyst allowing healing. Significant differences were not observed among results from different locations. PMID:19308555

Treatment of a spinal aneurysmal bone cyst using combined image-guided cryoablation and cementoplasty.  

PubMed

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

Simple Signaling Molecules for Inductive Bone Regenerative Engineering  

PubMed Central

With greater than 500,000 orthopaedic procedures performed in the United States each year requiring a bone graft, the development of novel graft materials is necessary. We report that some porous polymer/ceramic composite scaffolds possess intrinsic osteoinductivity as shown through their capacity to induce in vivo host osteoid mineralization and in vitro stem cell osteogenesis making them attractive synthetic bone graft substitutes. It was discovered that certain low crystallinity ceramics partially dissociate into simple signaling molecules (i.e., calcium and phosphate ions) that induce stem cells to endogenously produce their own osteoinductive proteins. Review of the literature has uncovered a variety of simple signaling molecules (i.e., gases, ions, and redox reagents) capable of inducing other desirable stem cell differentiation through endogenous growth factor production. Inductive simple signaling molecules, which we have termed inducerons, represent a paradigm shift in the field of regenerative engineering where they can be utilized in place of recombinant protein growth factors.

A Giant Simple Liver Cyst That Caused Increases in Serum CA 19-9 and CA 15-3 Levels  

PubMed Central

Simple cysts (SCs) of the liver are not associated with the biliary malformations in intrahepatic bile duct biliary. Seen in 0.1% to 7% of adult population, biliary malformations are more common in women. The levels of glycoprotein-like tumor markers (carbohydrate antigen (CA) 19-9) in the cysts and serum could be high. Although studies regarding CA 19-9 exist, sufficient data on cancer antigen (CA) 15-3 are not available. This case is about a 76-year-old woman who complained of painless intra-abdominal mass. The patient with a giant simple cyst extending from the gallbladder to the pelvis had preoparative CA 19-9 and CA 15-3 serum levels of 87.3 IU/L and 37 IU/L respectively. It was observed that CA 19-9 levels had decreased to 36 IU/L and CA 15-3 to 28.1 IU/L in blood samples taken in the third month after the surgery. There is a need for comprehensive studies to investigate the relationship between the size of the cyst and biomarkers (including markers such as CA 15-3) in the assesment of liver SC. PMID:25247025

Cytogenetic and molecular cytogenetic findings in 43 aneurysmal bone cysts: aberrations of 17p mapped to 17p13.2 by fluorescence in situ hybridization.  

PubMed

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

The comparative study of Yaz and Ovocept-ld on patients with simple ovarian cysts referring to Iran-Isfahan Shariati Hospital  

PubMed Central

Background: Functional ovarian cysts include follicular, corpus luteum, and theca lutein cysts are the most common adnexal masses (about 50%) in women of reproductive age. 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 ?g 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 ?g 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

Pelvic Girdle Reconstruction Based on Spinal Fusion and Ischial Screw Fixation in a Case of Aneurysmal Bone Cyst  

PubMed Central

A case of lytic lesion of the pelvis in a 23-year-old woman is presented. A biopsy led to the diagnosis aneurysmal bone cyst (ABC). Due to the histologically very aggressive growth of the tumor, a low malignant osteosarcoma could not be excluded. In an initial operation the tumour, affecting the sacrum, the iliac crest and the lower lumbar spine was resected. Temporary restabilisation of the pelvic ring was achieved by a titanium plate. The histological examination of the entire tumour confirmed the diagnosis ABC. After 6 months, the MRI showed no recurrence. The observed tilt of the spine to the operated side on the sacral base prompted a second surgical procedure: a transpedicular fixation of L5 and L4 was connected via bent titanium stems to the ischium, where the fixation was achieved by two screws. This construction allowed the correction of the base angle and yielded a stable closure of the pelvic ring. The patient has now been followed for 6 years: the bone grafts have been incorporated and, in spite of radiological signs of screw loosening in the ischium, the patient is fully rehabilitated and free of symptoms. Pedicle screws in the lower spine can be recommended for fixation of a pelvic ring discontinuity. PMID:18521384

Aneurysmal bone cyst does not hinder the success of kidney transplantation. A case report.  

PubMed

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.

Resection of an upper cervical aneurysmal bone cyst and spinal reconstruction using a midline mandibular osteotomy in a pediatric patient.  

PubMed

The authors report on the surgical management of an extensive lesion of the upper cervical spine that required an uncommon transmandibular approach to facilitate exposure, resection, and stabilization in a pediatric patient. A 6-year-old boy with a large aneurysmal bone cyst of the C-2 vertebra presented with progressive weakness and right-sided neck pain. The lesion extended laterally into the soft tissue of the neck, inferiorly to C-4, and posteriorly around the spinal cord. A transmandibular osteotomy was performed to provide adequate exposure for complete resection of the mass and anterior C1-3 instrumentation and fusion. Subsequently, the patient underwent occiput to C-4 posterior instrumentation and fusion. The patient tolerated the operation well and had regained all function at 3 and 11 months' follow-up. No neurological complications or problems of speech, swallowing, or respiration occurred. Even in pediatric patients, the transmandibular approach for the treatment of upper cervical spine lesions is an effective method of maximizing exposure for complex lesions requiring resection and stabilization.

Primary intraosseous hybrid nerve sheath tumor of femur: A hitherto undescribed occurrence in bone with secondary aneurysmal bone cyst formation resulting in pathological fracture.  

PubMed

Soft tissue perineurioma besides its pure form may coexist with schwannoma as hybrid nerve sheath tumor (HNST) which occurs in the limbs, head and neck, trunk and occasionally colon but origination in other organ sites has not been reported. We report the first case of primary intraosseous HNST. An 18-year-old man suffered from pathological fracture of his right femur after an impact which was preceded by a similar episode two weeks previously. Plain radiograph revealed a displaced fracture in the superior diaphysis of the right femur where an expansile osteolytic lesion with relatively well defined borders was seen. Histologic examination of the curetted lesion showed a well circumscribed spindle cell neoplasm displaying predominantly storiform but focally whorled patterns. In areas, the cells possessed thin wavy spindle nuclei and delicate elongated bipolar cytoplasmic processes supported in a fibromyxoid stroma. They stained positively for EMA, claudin, CD34, collagen 4 and focally for S100 but negatively for MUC4 and BCL-2, indicative of perineurial differentiation. Situated in the periphery of some of these perineurial whorls are spindle cells bearing plump tapering wavy nuclei and palely eosinophilic cytoplasm with indistinct cell borders. They stained intensely for S100 but negatively for EMA, claudin, CD34, collagen 4, MUC4 and BCL-2, consistent with schwannian differentiation. Focally, these two varieties of cells intimately intermingled with each other. Features of aneurysmal bone cyst (ABC) formation were present but no mitotic figures, establishing the final diagnosis of primary intraosseous HNST with secondary ABC formation. The patient remained well 7 months after curettage and internal fixation of his fracture. PMID:25466465

Imaging of ectopic thyroid tissue and thyroglossal duct cysts.  

PubMed

When a child or young adult presents with a mass in the anterior portion of the neck, diagnostic considerations include a thyroglossal duct cyst and ectopic thyroid tissue. These entities are often suspected clinically, and imaging provides an opportunity to evaluate the extent, confirm the diagnosis, and evaluate for complications. Imaging characteristics of a thyroglossal duct cyst as a simple cyst and of ectopic thyroid tissue as a hyperattenuating soft-tissue mass can help identify these lesions at computed tomography (CT); however, intrinsic magnetic resonance, CT, and ultrasonographic imaging characteristics alone cannot be used to confirm the diagnosis. Rather, knowledge of the typical course of the thyroid primordium during embryologic development is essential to understand the variant locations along this path where thyroid tissue can be found. The migration of thyroid primordium begins at the foramen cecum at the base of the tongue and then loops around the hyoid bone anteriorly and inferiorly and descends anteriorly to the thyrohyoid membrane into the orthotopic location in the infrahyoid portion of the neck. Thyroid ectopia is categorized into one of four typical locations with respect to this embryologic course: (a) the base of the tongue, (b) adjacent to the hyoid bone, (c) the midline infrahyoid portion of the neck, and, rarely, (d) the lateral part of the neck. The differential diagnosis includes metastatic thyroid carcinoma, branchial cleft cyst, lymphatic malformation, abscess, saccular cyst, epidermoid cyst, and squamous cell carcinoma. The relationship of a mass to landmarks such as the foramen cecum, hyoid bone, strap muscles, thyrohyoid membrane, and thyroid cartilage can help differentiate a thyroglossal duct cyst and ectopic thyroid tissue from other anterior neck masses when the embryologic thyroid course is considered.

Unknown partner for USP6 and unusual SS18 rearrangement detected by fluorescence in situ hybridization in a solid aneurysmal bone cyst.  

PubMed

USP6 rearrangement is the most common genetic abnormality in primary aneurysmal bone cyst, and SS18 rearrangement has not been previously described in any type of tumor where synovial sarcoma was excluded from the differential diagnosis. We report a case of solid aneurysmal bone cyst in which fluorescence in situ hybridization (FISH) analysis indicated rearrangements of both USP6 and SS18, but histologic features were consistent with aneurysmal bone cyst throughout the lesion. Reverse-transcription polymerase chain reaction (RT-PCR) for the SS18-SSX1 and SS18-SSX2 translocations, identity testing, and SS18 FISH were performed on cytogenetic monolayer cultures and formalin-fixed paraffin-embedded (FFPE) tissue. Genomic microarray, FISH, and immunohistochemistry were performed on follow-up studies of the FFPE specimen. The karyotype was 45,X,add(X)(p11.2),add(4)(q13),add(8)(p21),-13,add(17)(p11.2),add(18)(q11.2) in all 20 cells analyzed from monolayer cultures. The karyotype showed no cytogenetically visible alterations of chromosomal regions harboring known partners for USP6. Metaphase FISH with a commercial SS18 break-apart probe showed translocation of the 5' portion of the SS18 probe to the short arm of the derivative X, as is observed in synovial sarcoma. RT-PCR showed no evidence of a SS18-SSX fusion, and immunohistochemistry was negative for TLE1, EMA, and cytokeratin AE1/3 expression. FISH on FFPE sections with a custom break-apart probe flanking USP6 showed evidence for a USP6 rearrangement throughout the tumor (25-50%). FISH on FFPE sections with a commercial SS18 break-apart FISH probe showed more variable results (0-50% split signals). There was no evidence of a SS18-USP6 fusion by FISH or RT-PCR. A molecular inversion probe array revealed a deletion encompassing the entire SS18 gene and its promoter, as well as portions of the region targeted by the commercial SS18 FISH probe. In conclusion, results obtained from commercially available FISH probes may occasionally yield misleading results. In this case, the SS18 rearrangement by FISH resulted from a complex rearrangement of 18q11.2 with a deletion of the SS18 gene. The translocation partner for USP6 remains unknown in this case.

Percutaneous intramedullary decompression, curettage, and grafting with medical-grade calcium sulfate pellets for unicameral bone cysts in children: a new minimally invasive technique.  

PubMed

Several treatment options exist for unicameral bone cysts (UBCs), including observation, steroid injection, bone marrow injection, and curettage and bone grafting. These are all associated with high recurrence rates, persistence, and occasional complications. Newer techniques have been described, most with variable success and only short follow-up reported. Because of these factors, a new minimally invasive percutaneous technique was developed for the treatment of UBCs in children. Twenty-eight children with UBCs who underwent percutaneous intramedullary decompression, curettage, and grafting with medical-grade calcium sulfate (MGCS) pellets by the senior author (J.P.D.) between April 2000 and April 2003 were analyzed as part of a pediatric musculoskeletal tumor registry at a large tertiary children's hospital. Four patients were lost to follow-up, and the remaining 24 patients had an average follow-up of 21.9 months (range 4-48 months). Twelve patients were followed for at least 24 months. Six of the 24 children had received previous treatment of their UBC, most often at an outside institution. Follow-up was performed through clinical evaluation and radiographic review. Postoperative radiographs at most recent follow-up showed complete healing, defined as more than 95% opacification, in 22 of 24 patients (91.7%). One patient (4.2%) demonstrated partial healing, defined as 80% to 95% opacification. One patient had less than 80% radiographic healing (4.2%). All 24 patients returned to full activities and were asymptomatic at most recent follow-up. The only complication noted was a superficial suture abscess that occurred in one patient; this resolved with local treatment measures. The new minimally invasive technique of percutaneous intramedullary decompression, curettage, and grafting with MGCS pellets demonstrates favorable results with low complication and recurrence rates compared with conventional techniques. The role of intramedullary decompression as a part of this percutaneous technique is discussed. PMID:16294140

Semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts of the knee at 3T MRI: A comparison between intermediate-weighted fat-suppressed spin echo and Dual Echo Steady State sequences  

PubMed Central

Background Choice of appropriate MR pulse sequence is important for any research studies using imaging-derived data. The aim of this study was to compare semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts using intermediate-weighted (IW) fat-suppressed (fs) spin echo and Dual Echo Steady State (DESS) sequences on 3 T MRI. Methods Included were 201 subjects aged 35-65 with frequent knee pain. 3T MRI was performed with the same sequence protocol as in the Osteoarthritis Initiative (OAI). In a primary reading subchondral bone marrow edema-like lesions were assessed according to the WORMS system. Two hundred subregions with such lesions were randomly chosen. The extent of subchondral bone marrow edema-like lesions was re-evaluated separately using sagittal IW fs and DESS sequences according to WORMS. Lesion size and confidence of the differentiation between subchondral bone marrow edema-like lesions and subchondral cysts located within or adjacent to them was rated from 0 to 3. Wilcoxon signed-rank tests and chi-square statistics were used to examine differences between the two sequences. Results Of 200 subchondral bone marrow edema-like lesions detected by IW fs sequence, 93 lesions (46.5%) were not depicted by the DESS sequence. The IW fs sequence depicted subchondral bone marrow edema-like lesions to a larger extent than DESS (p < 0.0001), and the opposite was true for subchondral cysts. Confidence scores for differentiation of the two types of lesions were not significantly different between the two sequences. Conclusions In direct comparison the IW fs sequence depicts more subchondral bone marrow edema-like lesions and better demonstrate the extent of their maximum size. The DESS sequence helps in the differentiation of subchondral bone marrow edema-like lesions and subchondral cysts. The IW fs sequence should be used for determination of lesion extent whenever the size of subchondral bone marrow edema-like lesions is the focus of attention. PMID:21906292

The Photodynamic Bone Stabilization System: a minimally invasive, percutaneous intramedullary polymeric osteosynthesis for simple and complex long bone fractures  

PubMed Central

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.

Cell based advanced therapeutic medicinal products for bone repair: Keep it simple?  

PubMed

The development of cell based advanced therapeutic medicinal products (ATMPs) for bone repair has been expected to revolutionize the health care system for the clinical treatment of bone defects. Despite this great promise, the clinical outcomes of the few cell based ATMPs that have been translated into clinical treatments have been far from impressive. In part, the clinical outcomes have been hampered because of the simplicity of the first wave of products. In response the field has set-out and amassed a plethora of complexities to alleviate the simplicity induced limitations. Many of these potential second wave products have remained "stuck" in the development pipeline. This is due to a number of reasons including the lack of a regulatory framework that has been evolving in the last years and the shortage of enabling technologies for industrial manufacturing to deal with these novel complexities. In this review, we reflect on the current ATMPs and give special attention to novel approaches that are able to provide complexity to ATMPs in a straightforward manner. Moreover, we discuss the potential tools able to produce or predict 'goldilocks' ATMPs, which are neither too simple nor too complex. PMID:25451134

Bronchogenic Cyst  

PubMed Central

The clinical presentation of the bronchogenic cyst is variable, from respiratory distress at birth to late appearance of symptoms. In order to determine clinical features and treatments, we retrospectively studied the medical records and pathology reports of all patients with bronchogenic cysts (n = 22) referred to our surgical department from February 1985 through January 2002. They included 18 male and 4 female patients with an age range of 1 to 38 years (average, 16.4 years). There were 14 mediastinal, 2 hilar, and 6 intrapulmonary bronchogenic cysts. Symptoms were present in 18 of the 22 patients. Cough was the most common symptom (45%). Ten patients (45%) presented with complications: severe hemoptysis, pneumothorax and pleuritis, esophageal compression, infected cyst, and postobstructive pneumonia. In all patients, complete resection of the bronchogenic cyst was performed by thoracotomy. A postoperative sequela occurred in only 1 patient, who had a persistent air leak. There were no late sequelae, nor was there a recurrence of the cyst. The follow-up period ranged from 8 months to 12 years (mean, 5.2 years). Because a confident preoperative diagnosis is not always possible and because complications are common, we recommend surgical resection of all suspected bronchogenic cysts in operable candidates.

CD1a-positive cells in odontogenic cysts.  

PubMed

Langerhans cells (LC) are bone marrow-derived cells that have a CD1a-positive immunophenotype and are an important portion of the cell-mediated immune response. The aim of this study was an immunohistochemical evaluation of CD1a positive cells in different types of oral cysts. Fifty-five cysts were studied: 18 odontogenic keratocysts (OKC), of which five were orthokeratotic and 13 parakeratotic; 19 radicular cysts; and 18 dentigerous cysts. Positive LC was 80% for orthokeratotic OKC, 33% for parakeratotic OKC, approximately 35% for radicular cysts, and approximately 20% for dentigerous cysts. The results show that OKC with well-differentiated epithelial linings presented a greater number of LC than the other cysts. However, when the cyst wall was inflamed there were no differences in LC expression in the different types of cysts. The data confirm that LC distribution seems to be associated with the degree of differentiation of the epithelia. PMID:12043859

Odonto calcifying cyst  

PubMed Central

The calcifying odontogenic cyst (COC) is reported to be associated with odontoma in 24% of cases. Separation of the cases of calcifying odontogenic cyst associated with odontoma (COCaO) may lead to a better understanding of the pathogenesis of this lesion. The literature revealed 52 cases of COCaO. The male to female ratio was 1:1.9, with a mean age of 16 years. Most common location was the maxilla (61.5%). The radiographic appearance of most cases (80.5%) was a well-defined, mixed radiolucent-radiopaque lesion. Histologically, the lesions consisted of a single large cyst with tooth-like structures as an integral part, giving the impression of a single lesion. In addition to the unique histologic features, differences in gender and distribution were found between the cases of COCaO and those of simple COC. COCaO may be regarded as a separate entity and classified as a benign, mixed odontogenic tumor. The term odontocalcifying odontogenic cyst is suggested. PMID:23853467

A simple method for the repair of frontal sinus fracture: the bone mesh pull-up technique.  

PubMed

Accurate reduction and stable fixation are important in the treatment of frontal sinus fracture. In this article, we introduce a rapid and simple method for the treatment of frontal fractures and restoration of normal forehead contour, named the "bone mesh pull-up technique" (BMPUT). We describe our experience with this technique in frontal trauma cases, with emphasis on the technical aspects and clinical results of this simple method. Postoperative computed tomography scans showed adequate reduction of displaced bone fragments in all cases. Esthetic results were satisfactory and no complications related to this procedure, such as uncontrollable sinus bleeding, infection, and posterior table and brain injuries, were observed. Follow-ups ranged from 1 to 24 months, with an average of 12 months. Contour deformities were effectively restored and cosmetic results were very good. The BMPUT is a safe procedure that can be performed with minimal morbidity and offers, good access, and excellent esthetic results. PMID:24624261

Endoscopic transsphenoidal surgery of Rathke's cleft cyst.  

PubMed

Rathke's cleft cysts (RCC) are benign lesions that originate from remnants of Rathke's pouch. They can compress adjacent structures causing visual loss and endocrine dysfunction. The endoscopic endonasal transsphenoidal approach (EETA) has gained popularity in the surgical management of pituitary and parasellar tumors. However, postoperative cyst recurrence and endocrine dysfunction are still major concerns. A retrospective chart review was performed on 11 patients who underwent a purely EETA. Subtotal resection of the cyst wall with drainage of the intracystic contents followed by obliteration of the cyst with a fat graft was performed in all patients. Two patients underwent repeated surgeries for symptomatic cyst recurrence. One patient ultimately underwent extracapsular removal of the entire cyst wall because of multiple recurrences after simple drainage. There were no incidences of new permanent hypopituitarism, visual deficits, or postoperative cerebrospinal fluid leaks. All patients reported an improvement of initial preoperative symptoms. A non-aggressive strategy of partial cyst wall removal and simple drainage of cyst contents via EETA is a viable approach for surgical treatment of RCC with a low rate of postoperative endocrine and visual complications. A more aggressive strategy of extracapsular removal of the cyst wall may be indicated in patients with repeated recurrence. PMID:25284127

Unusual Postrhinoplasty Complication: Nasal Dorsum Cyst  

PubMed Central

Among all the possible complications of aesthetic rhinoplasty, a rare one is the development of cystic masses on the nasal dorsum: several theories suggest that cysts develop commonly by entrapment of nasal mucosa in the subcutaneous space, but they can also originate from foreign body reactions. This report deals with two cases of nasal dorsum cysts with different pathogenesis: both patients had undergone aesthetic rhinoplasty in the past (26 years ago and 14 years ago, resp.). Both cystic masses were removed via a direct open approach and nasal reconstruction was performed successfully with autologous vomer bone. The pathologic investigations showed a foreign body inclusion cyst associated with latex rubber in the first case and a sequestration of a mucosal-lined nasal bone was not removed at the time of primary rhinoplasty in the second case. A brief review of the literature focuses on the pathophysiology and treatment options for nasal dorsal cysts following aesthetic rhinoplasty. PMID:25276458

Growth plate stress distribution implications during bone development: A simple framework computational approach.  

PubMed

Mechanical stimuli play a significant role in the process of long bone development as evidenced by clinical observations and in vivo studies. Up to now approaches to understand stimuli characteristics have been limited to the first stages of epiphyseal development. Furthermore, growth plate mechanical behavior has not been widely studied. In order to better understand mechanical influences on bone growth, we used Carter and Wong biomechanical approximation to analyze growth plate mechanical behavior, and explore stress patterns for different morphological stages of the growth plate. To the best of our knowledge this work is the first attempt to study stress distribution on growth plate during different possible stages of bone development, from gestation to adolescence. Stress distribution analysis on the epiphysis and growth plate was performed using axisymmetric (3D) finite element analysis in a simplified generic epiphyseal geometry using a linear elastic model as the first approximation. We took into account different growth plate locations, morphologies and widths, as well as different epiphyseal developmental stages. We found stress distribution during bone development established osteogenic index patterns that seem to influence locally epiphyseal structures growth and coincide with growth plate histological arrangement.

Contribution of endosonography in an uncommon case of pancreatic cysts  

PubMed Central

Here we present the case of a 35-year-old female patient with long standing dyspepsia and imaging studies showing the presence of multiple cysts in the head and tail of the pancreas. The patient underwent endosonography that confirmed the presence of multiple simple cysts throughout the entirety of the pancreas without dilation of the pancreatic duct. The majority of the cysts were less than one centimeter in size, and the largest cyst showed a honeycomb appearance. Cytology of aspirates from the two largest cysts was compatible with benign pancreatic cysts. Endosonography also revealed cysts within the left kidney and spleen. Genetic testing confirmed Von Hippel-Lindau disease. We highlight this case because it is unusual for Von Hippel-Lindau disease, a rare clinical entity, to present solely with cysts in the absence of more common manifestations, such as hemangioblastomas in the central nervous system and malignancy.

A simple and efficient method for deriving neurospheres from bone marrow stromal cells  

SciTech Connect

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.

Efficacy of Platelet-Rich-Plasma (PRP) and Highly Purified Bovine Xenograft (Laddec®) Combination in Bone Regeneration after Cyst Enucleation: Radiological and Histological Evaluation  

PubMed Central

ABSTRACT Objectives The purpose of the present study was to evaluate the efficacy of adding platelet-rich plasma (PRP) to a new highly purified bovine allograft (Laddec®) in the bone regeneration of cystic bony defects augmented following cystectomy. Material and Methods Study sample included 20 patients undergoing cystectomy in which the bone defect was filled with PRP and Laddec®. All patients were examined with periapical radiographs before operation and at follow-up. After 3 months, at re-entry surgery for implant placement, bone core was taken for histological and histomorphometric analysis. Results The postoperative successive radiographs showed a good regeneration of bone in the height of bony defects with application of PRP to bone graft. By the first postoperative month, about 48% of the defect was filled, which gradually increased in each month and showed about 90% of defect-fill by 6 months. Histological and histomorphometric analysis, showed a significant presence of bone tissue and vessels, with newly formed bone in contact with anorganic bone particles. The mean volume of vital bone was 68 ± 1.6% and the mean percentage of vital bone was 48 ± 2.4%. The mean percentage of inorganic particles in tissues was 20 ± 1.2% of the total volume. All the samples analyzed did not evidence the presence of inflammatory cells. Conclusions The results of this study showed how the use of Laddec® in association with platelet-rich plasma allows bone regeneration and has a potential for routine clinical use for regeneration of cystic bony defects.

[Tarlov cysts: report of four cases].  

PubMed

Four perineurial cysts cases (Tarlov's cysts) are reported. The purpose of this study is to describe and to compare them with data from a literature review. The evaluation was performed among 88 adult patients with symptoms of radiculopathy, sacral pain, low back pain. Four patients revealed Tarlov's cysts (4.5%). The diagnosis was made by magnetic resonance imaging. Four cases underwent sacral laminectomy. Following surgery, the claudication pain resolved with no motor or sensory deficits. Tarlov's cysts should be considered as a differential diagnosis of sacral radiculopathy, sacral or lumbar pain syndromes and mainly to the lumbar disc prolapse. The goal of the surgical treatment is to relieve the neural compression and stop bone erosion. PMID:15334232

A hydatid cyst of the thyroid gland.  

PubMed

Echinococcosis, although eradicated in many countries, is still widespread in communities in which agriculture is dominant, and cystic hydatidosis is a significant public health problem in regions where echinococcosis is endemic. Hydatid cysts may be found in almost any part of the body, but most often in the liver and lungs. Other organs affected occasionally include the brain, muscle, kidney, bone, heart and pancreas. This report documents a rare case with a cystic nodule in the thyroid detected by ultrasonography. The patient was a 40-year-old woman with an euthyroid multinodular goitre. Ultrasonography revealed a cystic nodule, and the ultrasonic appearance of the cyst liquid showed multiple echoes, suggesting that the nodule could be a hydatid cyst. Bilateral subtotal thyroidectomy was performed. Postoperative examination of the nodule showed it to be a solitary primary thyroid hydatid cyst. PMID:12025531

An Abnormal Bone Lesion of the Scapula in a Collegiate Basketball Player: A Case Report  

PubMed Central

Objective: To present the case of a bone lesion of the scapula in a collegiate basketball player. Background: A 19-year-old National Collegiate Athletic Association Division I male basketball player presented with pain in the posterior region of the right shoulder. During practice, he was performing a layup when his arm was forced into hyperflexion by a defender. Evaluation revealed a bone lesion involving the scapular spine and base of the acromion. Differential Diagnosis: Acromioclavicular joint sprain, subacromial bursitis, subscapular bursitis, humeral head contusion, acromial fracture. Treatment: The patient was treated for 2 months with therapeutic modalities and rehabilitation exercises. Because of persistent pain and the risk of a pathologic fracture, open surgical biopsy and bone grafting were then undertaken. Uniqueness: Most simple bone cysts affect the proximal humerus and femur, whereas our patient's lesion was in the acromial complex. Conclusions: Athletic trainers should be alert to the unusual possibility of bone cysts, which are usually identified incidentally when radiographs are obtained for other reasons. Most simple bone cysts are asymptomatic, but a pathologic fracture can occur with trauma. PMID:23725460

Intratarsal Keratinous Cyst – An Emerging Entity  

PubMed Central

We report two cases of recurrent intratarsal keratinous cysts of the Meibomian gland, a recently described lesion thought to have been previously misdiagnosed. The correct diagnosis can be made based on histopathologic features alone, although expression of cytokeratin (CK) 5/6 in the cyst epithelium is a specific marker of these lesions. Recognition of these lesions, and distinguishing them from other intratarsal cysts that do not recur, is important to guide definitive therapy via full-thickness excision rather than simple incision and drainage.

Haematic cyst formation after orthognathic surgery.  

PubMed

A 34-year-old man suffered from discomfort originating from a mass located in his right zygomatic area. He developed orbital symptoms, such as diplopia, which lasted for 5 months. He also suffered from Crouzon's syndrome and had undergone a Lefort III osteotomy 9 years prior for correction of midfacial hypoplasia. The size of the mass slowly increased and his orbital symptoms developed further, eventually leading to surgical exploration. During the operation, a mass was found near titanium plates which had been used to fix bone segments during a previous surgery. The total mass, including the capsule, was excised. The pathologic report was a chronic haematic cyst with a non-neoplastic collection of blood or blood products that exerted a mass effect in the orbit and adjacent tissues. The causes of haematic cysts are diverse, with trauma being the most common. Although haematic cysts resulting from trauma have been widely reported, there have been few reports on haematic cysts associated with orthognathic surgeries, such as Lefort III osteotomies. This case demonstrates that haematic cysts may be delayed complications of major bone surgery and that surgeons and patients should be aware of this possibility. PMID:21807573

Pancreatic cyst fluid analysis--a review.  

PubMed

An increased number of pancreatic cysts are being diagnosed due to the increased usage of cross-sectional imaging. Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) cytology and molecular analysis of these cystic lesions have led to their better detection and characterization. The aim of this review is to assess the value of cyst fluid analysis for the differential diagnosis of pancreatic cystic lesions, in view of the recent progresses of molecular analysis methods. Pancreatic cysts can be either simple (retention) cysts, pseudocysts and cystic neoplasms, while these are further subdivided into serous cystadenomas, mucinous cystic neoplasms (MCNs) or intraductal papillary mucinous neoplasms (IPMNs). EUS is now being used to investigate cystic pancreatic lesions, particularly by means of EUS guided cyst aspiration and sampling of the cyst wall or septa, as well as mural nodules. Cyst fluid can be further studied after aspiration in order to analyze cytology, viscosity, extracellular mucin, other tumor markers (CEA, CA 19-9,CA 15-3, Ca 72-4, etc.), enzymes (amylase, lipase), as well as DNA analysis of DNA quality/content or mutational analysis to study allelic imbalance/LOH (loss of heterozygosity) and K-ras mutations. After careful review of the published studies, a conclusion was reached that the use of tumor and molecular markers in conjunction with multimodality detection methods such as CT, MR and EUS-FNA allows risk stratification, while being also cost-effective.

Nasolabial cysts: clinical features, diagnosis, and treatment.  

PubMed

The aim of this study was to review our experience, examine the clinical and pathological features of nasolabial cysts, and to provide a basis for the diagnosis and treatment in an Asian population. We made a retrospective review of patients with nasolabial cysts who were treated at the Department of Otolaryngology, Tan Tock Seng Hospital between January 1999 and December 2004. Clinical data, presenting symptoms, clinical features, pathological findings, preoperative investigations, treatment, and outcome were analysed for each case. We found 17 patients with nasolabial cysts. The findings of adult onset, higher incidence among women and preponderance on the left side confirmed current opinion. The clinical diagnosis of nasolabial cyst was accurate in all cases. Preoperative computed tomograms (CTs) done for one patient did not alter the management. All patients had the cysts excised completely through a sublabial incision. Breaches of the nasal vestibular mucosa healed spontaneously without repair. Histopathological examination showed that cysts were lined with pseudostratified columnar (n=9), stratified squamous (n=4), mixed respiratory and squamous epithelium (n=3), and simple cuboidal epithelium (n=1). No patient developed complications or recurrences. Nasolabial cysts are relatively common in Singapore, and the diagnosis must be kept in mind if they are to be treated early. Diagnosis is based on clinical features and the treatment of choice is complete excision. PMID:17030357

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

Epidermoid cyst of gastrointestinal tract is very rare, and only a few cases of epidermoid cyst of the caecum have been reported in the literature. We report the first case of epidermoid cyst of the caecum in an elderly man, mimicking mesenteric cyst clinically. It was treated by laparoscopic excision of the cyst. The cyst was spherical, extending from and expanding the serosal surface of the caecum with no communication through the muscularis wall. Histologically, the inner lining of the cyst was composed of benign, mature, keratinised and stratified squamous epithelium with a well-formed granular layer. On opening, the cyst contained pultaceous cheesy material. No calcification, hair, teeth or bone elements were detected. PMID:23302551

A simple approach for synthesis, characterization and bioactivity of bovine bones to fabricate the polyurethane nanofiber containing hydroxyapatite nanoparticles  

PubMed Central

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.

A case of sacral hydatid cyst  

PubMed Central

INTRODUCTION Hydatid cyst of bone constitutes only 0.5-2% of all hydatidoses. The thoracic spine is the most common site of spinal hydatidoses. Primary hydatid cyst of the sacral spinal canal is rare. PRESENTATION OF CASE A 19-year-old man had cauda equina syndrome with pelvic pain 15 days ago, the pelvic radiography shows a lytic image depend on the left sacral wing. MRI showed an intra-pelvic cystic image invading the sacrum T1 hypointense and T2W hyperintense. The Hydatid serology was positive.Surgical treatment consisted of a wide drainage of hydatid cavity dug in the left sacral wing, and by which it communicated intra pelvic, with removal of the entire cyst by gentle aspiration, abundant rinsing with hypertonic saline, release and sacred roots encompassed in a puddle of fibrosis hydatid.The evolution was good with recovery of perineal sensation and anal tone. The sacroiliac joint was considered stable and did not require synthesis or reconstruction. DISCUSSION Hydatid cysts predominantly occur in liver and lungs. Involvement of other organs is uncommon. Neither surgery nor medical therapy is generally effective for bone, especially spinal hydatidosis. The initial treatment of choice is surgical excision for neural decompression and establishing diagnosis. Albendazole is the drug of choice against this disease, when suspected, presurgical use of Albendazole in Echinococcus infestations reduces risk of recurrence and/or facilitates surgery by reducing intracystic pressure. CONCLUSION A missed diagnosis of hydatid cyst could be devastating. Hence, hydatid cyst should be kept as a differential diagnosis, when encountered with a cystic lesion of sacrum. In addition, longterm follow-up is mandatory as recurrence is high despite use scolicidal agents. PMID:24912110

Rare Nonneoplastic Cysts of Pancreas  

PubMed Central

Pancreatic cysts represent a small proportion of pancreatic diseases, but their incidence has been recently increasing. Most pancreatic cysts are identified incidentally, causing a dilemma for both clinicians and patients. In contrast to ductal adenocarcinoma, neoplastic pancreatic cysts may be cured by resection. In general, pancreatic cysts are classified as neoplastic or non-neoplastic cysts. The predominant types of neoplastic cysts include intraductal papillary mucinous neoplasms, mucinous cystic neoplasms, serous cystic neoplasms, and solid pseudopapillary neoplasms. With the exception of serous type, neoplastic cysts, have malignant potential, and in most cases requires resection. Non-neoplastic cysts include pseudocyst, retention cyst, benign epithelial cysts, lymphoepithelial cysts, squamous lined cysts (dermoid cyst and epidermal cyst in intrapancreatic accessory spleen), mucinous nonneoplastic cysts, and lymphangiomas. The incidence of nonneoplastic, noninflammatory cysts is about 6.3% of all pancreatic cysts. Despite the use of high-resolution imaging technologies and cytologic tissue acquisition with endosonography, distinguishing nonneoplastic from neoplastic cysts remains difficult with most differentiations made postoperatively. Nonetheless, the definitive distinction between non-neoplastic and neoplastic cysts is crucial as unnecessary surgery could be avoided with proper diagnosis. Therefore, consideration of these rare disease entities should be entertained before deciding on surgery. PMID:25674524

Validation of a simple and fast method to quantify in vitro mineralization with fluorescent probes used in molecular imaging of bone  

SciTech Connect

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.

Thyroglossal duct cysts: 20 years' experience (1992-2011).  

PubMed

The objective of the present study is to report on the clinical course and management of thyroglossal duct cysts. Retrospective review of all patients who underwent surgery for thyroglossal duct cysts between 2000 and 2013 at a tertiary referral center was carried out. The operations were performed using a modification of the Sistrunk operation: transcervical cystectomy, partial dissection of the hyoid bone, and dissection of all tracts identified during surgery. A total of 352 patients (176 men, 176 women) underwent surgery for a cyst (n = 282) or discharging sinus (n = 70). The mean age for the incidence of cysts was 26 years. Four of the patients (1.4 %) had a papillary thyroid carcinoma in the epithelium of the cyst. The follow-up period ranged from 7 months to 10 years. The overall recurrence rate was 4.5 %. Resection is often regarded as an elective surgical procedure in patients with thyroglossal duct cysts, but surgery should always be considered. Papillary thyroid carcinoma in the epithelium of the cyst is a rare but possible differential diagnosis. Dissection of all tracts found is recommended and partial dissection of the hyoid bone is mandatory. Dissection of the foramen cecum is not imperative. The recurrence rates with this approach are comparable to more extensive methods such as those described by Sistrunk. PMID:25135577

The authors present a case of a hemorrhagic adrenal cyst, one of the tumors known in literature as incidentalomas, emphasizing the clinical characteristics, since adrenal cysts or pseudocysts are generally rare and observed by chance during imaging procedures. Traditionally they are classified as pseudocysts, endothelial, epithelial or parasitic cysts. Laparoscopic adrenalectomy has been considered the treatment of choice for benign, functioning or non-functioning adrenal lesions. Small cystic adrenal tumors can be managed conservatively by laparoscopic decortication or marsupialization, but larger cysts should be treated by total or partial adrenalectomy. PMID:23045835

Management of adult choledochal cysts.  

PubMed Central

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.

We report the case of one of the largest prenatally detected fetal hemorrhagic cyst with ovarian torsion and fetal anemia leading to subsequent cesarean section delivery and further unilateral oophorectomy of the neonate. Usually, fetal ovarian cysts tend to resolve spontaneously within the first months after birth. There is no need of surgical treatment for such simple cysts. Routine sonographic examinations are obligatory, because in some cases complications such as massive hemorrhage, cyst rupture, or ovarian torsion with following infarction can occur. With the occurrence of these complex cyst signs by sonographic investigation, subsequent intervention should be considered by an interdisciplinary team. PMID:24027173

An unusual presentation of an intraosseous epidermoid cyst of the anterior maxilla: a case report  

PubMed Central

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.

Bilateral testicular epidermoid cysts are a very rare condition, with only a few reports in the literature. It is extremely important in this condition to make a correct pre-operative diagnosis on imaging to enable a testis-sparing surgery. PMID:21915385

Bilateral postoperative maxillary cysts after orthognathic surgery: A case report.  

PubMed

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

Testicular epidermoid cyst.  

PubMed

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

Infected solitary hepatic cyst.  

PubMed

An unusual case involving an infected hepatic cyst in which the correct diagnosis was made without operation is reported. A 93-year-old woman presented with acute onset of right upper quadrant abdominal pain, mild left lower quadrant abdominal pain, diarrhea, and fever. On admission, computed tomography revealed a 15 cm solitary hepatic cyst in the anterior-superior segment of the liver with a thickened wall that enhanced with contrast media. Ultrasonography demonstrated a 15 cm anechoic lesion with a hypoechoic area in the dependent portion of the cyst and a thickened wall. The serum concentration of C-reactive protein was 24.3 mg/dL, and the white blood cell count was 13,800/microL. A diagnosis of infected hepatic cyst was suspected, and percutaneous transhepatic drainage of the cyst was performed. Milky yellow fluid was obtained and the patient's right upper quadrant abdominal pain resolved after drainage. Klebsiella pneumoniae was cultured from the drainage fluid. The patient was discharged 20 days after drainage. Infection has not recurred and the hepatic cyst has not enlarged after 18 months. PMID:14685292

A simple, time-saving chairside device for radiographic diagnosis of vertical bone height and soft tissue thickness for implant placement--clinical report.  

PubMed

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

Intraperitoneal marsupialization of a giant para-pelvic renal cyst: A case report  

PubMed Central

Simple renal cysts are among the most common cystic lesions of the kidney. Renal cysts most often remain asymptomatic, but rarely these cysts may become huge in size and result in significant symptoms. Giant renal cysts present a technical challenge in terms of surgical management. Although laparoscopic procedures have been performed successfully at experienced centres, intraperitoneal marsupialization via open approach may be a feasible option at less experienced centres. We report a case of a young female with a giant (24 × 18 cm) renal cyst of Bosniak type-II variety. De-roofing and intraperitoneal marsupialization of the cyst was performed. At the 1-year follow-up, she was asymptomatic, with no residual cyst. PMID:25485019

Common Matrix Metalloproteinases (MMP-8, -9, -25, and -26) Cannot Explain Dentigerous Cyst Expansion  

PubMed Central

Objective: Mechanisms of the dentigerous cyst formation from the normal eruption follicle is unknown but disturbances in the proteolytic activity have been suspected, since the growth of these cysts is accompanied by local bone destruction. The aim of the present study was to evaluate the expression of matrix metalloproteinases (MMP) in human dental dentigerous cysts and healthy dental follicles. Materials and Methods: We studied 10 patients with dentigerous cysts and 10 healthy dental follicles from the lower jaw in respect to their immunoexpression of MMPs -8, -9, -25, and -26 and tissue inhibitor of metalloproteinases -1 (TIMP-1). Results: MMP-8 was expressed slightly more in cyst epithelium than in odontogenic epithelium of healthy controls dental follicle but the difference lacked statistical difference. Other MMPs and TIMP-1 did not differ regarding the studied specimens. Conclusion: Differences in MMP expression cannot solely explain the cyst expansion suggesting the potential involvement of other osteolytic mechanisms. PMID:25386530

A simple way to distinguish bed clothing contamination in a whole body bone scan: a case report  

PubMed Central

Whole body bone scan with Technetium-99m MDP (methylene diphosphate) can detect bony lesions due to altered osteoblastic activity. Non-physiologic or increased radiotracer uptake in the bony structures of patients with a history of malignant diseases is usually interpreted as being suspicious of bone metastasis. It is extremely important to properly distinguish false positive sites of Tc-99m MDP localization. We present three patients with the same pattern of Tc-99m MDP abnormality in different locations. These scans were all performed on the same day to evaluate possible bone metastases in three patients with breast carcinoma. After careful examination, repeated images revealed bed clothing contamination. This is different from bed contamination by displacement among different patients. It is also different from detector contamination by limited area of involvement where detector contamination appears as a line throughout the total body projection. It can be helpful if a nuclear medicine specialist has a brief look at all scans prior to reporting them. In cases where the same pattern of abnormality is repeated in all images, the possibility of technical error such as bed clothing contamination rather than a pathological abnormality should be borne in mind.

Intramedullary hydatid cyst of the cervical spine.  

PubMed

Hydatid disease (Echinococcosis) is a common parasitic infection caused by Echinococcus granulosus mainly in sheep-raising areas of the world. Liver, lungs and brain are the predominantly involved organs. However, 0.5-1% of the hydatid disease involves the spine and in 90% of the cases it is confined to the bone and the epidural space. Although intramedullary involvement is extremely rare, in this report, we present a 55-year-old female patient who was diagnosed with a cervical intramedullary hydatid cyst during magnetic resonance imaging of the cervical vertebrae. Accordingly, we imply that particularly in endemic areas, hydatid cyst disease should be kept in mind for the differential diagnosis of spinal mass lesions. PMID:23183479

A Simple and Effective Daily Pain Management Method for Patients Receiving Radiation Therapy for Painful Bone Metastases  

SciTech Connect

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.

Giant intraabdominal endometrial cyst.  

PubMed

Endometriosis is the condition where endometrium gets implanted and flourishes outside the uterine cavity, most commonly in ovary and on the peritoneum which lines the abdominal cavity and viscera. Endometrial cells in areas outside the uterus are influenced by hormonal changes and respond in a way similar to the endometrium inside the uterus. Symptoms often worsen with the menstrual cycle. We present a case of 50 years old female who presented with gross abdominal distension and abdominal pain over years. CT scan showed a huge intraabdominal cyst of unknown origin which was compressing adjacent structures. Patient underwent a high risk operation and whole cyst weighing 214 kg (471 lbs) was removed along with both ovaries and uterus. Histopathologically, it was reported as endometrial cyst.

Subcutaneous phaeohyphomycosis (mycotic cyst).  

PubMed

Phaeohyphomycosis designates fungal infections caused by pheoid or melanized fungi and characterized histopathologically by the presence of septate hyphae, pseudohyphae, and yeasts. Etiologic agents include Exophiala, Phoma, Bipolaris, Phialophora, Colletotrichum, Curvularia, Alternaria, Exserohilum, and Phialemonium sp. The most common are Exophiala jeanselmei and Wangiella dermatitidis. The clinical presentation depends on the immune status of the host: superficial (tinea nigra and black piedra); cutaneous (scytalidiosis) and corneal; subcutaneous (mycotic cyst); and systemic phaeohyphomycosis in the immunocompromised host. The mycotic cyst is a localized form, characterized by subcutaneous asymptomatic nodular lesions that develop after traumatic implantation of fungi, especially on the extremities. The average size of the cysts is 2.5 cm. KOH examination reveals pigmented yeasts, pseudohyphae, and hyphae. A cutaneous biopsy specimen usually shows an abscess or a suppurative granuloma with pigmented yeasts and pseudohyphae. The treatment of choice is surgical excision, but additional anti-fungal therapy is recommended for recurrent cases and immunocompromised patients. PMID:22682192

Bacteriological study of epidermal cysts.  

PubMed

The aim of this study was to determine whether bacterial infection plays a significant role in the inflammatory process of epidermal cysts. Samples from 152 patients (115 cases of inflamed and 37 of uninflamed epidermal cysts) were subjected to aerobic and anaerobic bacterial culture and the isolates were investigated. The rate of bacterial growth and the recovered anaerobes were significantly greater in the inflamed than the uninflamed epidermal cysts. However, it is difficult to determine whether recovered isolates from epidermal cysts represent "infection" or "colonization". In conclusion, this study revealed the predominance of anaerobes in inflamed cysts, strongly suggesting that anaerobes play a role in the inflammatory process. PMID:18176745

Renal Cysts and Urinomas  

PubMed Central

Renal cysts are a common imaging finding. Although most cysts never have symptoms, some cause pain, collecting system compression, hematuria, hypertension, and secondary infection. The mere presence of a cyst is not an indication for intervention, but treatment may be indicated in symptomatic patients or those with secondary obstruction. Urinomas generally are a contained collection of urine outside of the normal pathways where urine travels. As such, urinomas can arise anywhere from the upper abdomen down into the low pelvis and have a variety of etiologies. Ureteral obstruction with forniceal rupture and trauma (blunt, penetrating, or iatrogenic) are the most common causes of urinomas. When urinomas arise spontaneously, the likely cause varies with the patient's age. Blunt or penetrating trauma can cause perinephric urinomas by two mechanisms—direct disruption of the pelvis or collecting system or by degeneration of nonviable tissue. These urinomas are often perinephric, but can also occur in a subcapsular location. This review will discuss diagnosis, classification, and treatment of renal cysts and urinomas. PMID:23204636

Iatrogenic intraspinal epidermoid cyst.

Epidermoid cyst is generally regarded as congenital disease, and commonly related to other congenital spinal anomalies. However, it also develops iatrogenically. We report one rare case of epidermoid cyst that we experineced among intradural extramedullary tumors. A 21-year-old female patient was admitted to the hospital due to low back pain with radiating pain into a right lower extremity that initiated about a month ago. She complained sensory lose and motor weakness (grade 4+) on her right extremity as well as urinary dysfunction and sphincter dysfunction. She had a lumbar puncture three times due to Pneumococcal meningitis when she was 13 years old. The well-circumscribed intradural extramedullary mass of 1.8×1.6×4 cm size was found on the L4-5 in a magnetic resonance image. Gross total tumor removal was garried out after the total laminectomy L5 and partial laminectomy L4. The tumor mass was gray-colored and so fragile that it was easy to be removed. The histological diagnosis confirmed epidermoid cyst without malignancy. After the operation, the patient progressively showed remarkable neurological recovery. In this case, the cause of epidermoid cyst is considered iatrogenic concerning history of several times of lumbar puncture as meningitis. PMID:25346768

The Role of Choice-Lock Catheter and Trocar Technique in Percutaneous Ablation of Symptomatic Renal Cysts  

PubMed Central

Background: The most common benign lesions of the kidney are simple cysts. They are acquired lesions and mostly affect the elderly population. Objectives: To describe the usage of choice-lock catheter and trocar technique in percutaneous renal cyst treatment and determining long-term outcomes. Patients and Methods: This retrospective study was carried out between February 2000 and July 2011. Eighty-eight cysts all of which were Bosniak type-1 cysts were selected in 75 patients. The treatment indications were flank pain, hydronephrosis and hypertension. The choice-lock catheter was used for 84 cysts with the trocar technique. Ninety-five percent ethanol was used as the sclerosing agent. Maximum volume of the injected ethanol was 175 ml. The mean follow-up time after the treatment procedure was 23 months. Sixty-four cysts were located in the cortical and 24 cysts were located at the parapelvic region. Results: Fifty-seven cysts had complete regression, while 31 cysts regressed partially. After the procedure, pain was relieved in 44 (82%) patients and the pain alleviated in four (8%). Normotension was obtained in five (62.5%) of the eight hypertensive patients and no hydronephrosis was detected in nine patients. There were no relationship between the localization and the regression rate. No major complications occurred. Conclusions: Percutaneous ethanol sclerotheraphy in simple cysts is a safe, cost-effective and minimally invasive method. We consider that this technique may be an alternative solution in the percutaneous cyst treatment. PMID:25035702

Choledochoceles: are they choledochal cysts?  

PubMed

The classification of choledochoceles as a type of choledochal cyst stems from the 1959 article by Alonso-Lej and colleagues describing 94 choledochal cysts, only 4 of which were choledochoceles. Even then, Alonso-Lej questioned the propriety of including the choledochocele, stating it was unclear "as to whether or not it originates from the same etiologic factors [as other choledochal cysts]". In 1971, Trout and Longmire also questioned the validity of classifying choledochoceles as choledochal cysts, noting the anatomic position article and variant mucosa of the choledochocele. Wearn and Wiot, in an article titled "Choledochocele: not a form of choledochal cyst", cite the differences in clinical presentation, demographics, and histology as reasons why choledochoceles represent separate entities from choledochal cysts. Over the ensuing decades, numerous investigators have questioned the legitimacy of classifying choledochoceles as choledochal cysts. In our recent series (the only one to our knowledge directly comparing patients with choledochocele and other [type I, II, IV, and V] choledochal cysts), patients with choledochoceles differed from patients with choledochal cysts in their age, gender, presenting symptoms, history of previous cholecystectomy, pancreatobiliary ductal anatomy, management, and most importantly, propensity to developing biliary malignancy. Based on the available cases of choledochoceles found in the literature, combined with the recent series from our institution, we conclude that choledochoceles seem to be distinct entities from choledochal cysts.

Spatial and temporal variability of Alexandrium cyst fluxes in the Gulf of Maine: Relationship to seasonal particle export and resuspension  

NASA Astrophysics Data System (ADS)

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.

Conservative management of large radicular cysts associated with non-vital primary teeth: A case series and literature review.  

PubMed

Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin. Large radicular cyst is comparatively less frequently associated with primary teeth. They represent only 0.5-3.3% of the total number of cysts in primary dentition. Radicular cysts arising from deciduous teeth are reported to occur in age range of 3-19 years with a male predominance. Although large radicular cysts are treated by enucleation with extensive removal of bone and vital teeth, marsupialization can be preferred as a conservative approach to reduce the morbidity. The purpose of this article is to report a case series of large radicular cysts associated with badly mutilated and traumatized primary teeth and to demonstrate how best they can be conservatively treated during mixed dentition period.

They usually present in the 1st decade after the age of 2 years, possibly because the thymus attains its greatest development before puberty. They may be found anywhere along the normal descent route of the thymus gland from the mandible to the sternal notch; 50% extend into the mediastinum. Most patients are asymptomatic, although respiratory complications may occur. A review of the operative records in our hospital over the last 10 years revealed two cases of cervical thymic cysts (CTC) in a 5- and a 9-year-old boy. Both children presented with an atraumatic, painless, enlarging mass in the left side of the neck anterior to the sternocleidomastoid muscle. Neither boy had respiratory problems or swallowing difficulties. Ultrasound and computed tomography showed a lesion consistent with a tentative diagnosis of a branchial cyst in one boy and an extensive cystic hygroma in the other. Both lesions were approached through a transverse cervical incision and, although closely adherent to the internal jugular vein, carotid artery, and vagus nerve, were resected completely. There were no postoperative complications and so far there has been no recurrence. CTCs are uncommon benign lesions that should be considered in the evaluation of neck masses in children. Preoperative diagnosis is unusual and, at this time, there is no preoperative radiologic test that can accurately identify a neck mass as a CTC. Histologic investigation of the excised specimen showing thymic tissue remnants with pathognomonic Hassall's corpuscles and cholesterol clefts in the cyst wall is the only definitive diagnosis. Evolution is benign. Intact, complete surgical excision remains the treatment of choice. PMID:12415385

Skeletal muscle hydatid cysts presenting as soft tissue masses  

PubMed Central

Muscle hydatidosis is rare, accounting only for 3–5% of all cases. We present a case series of 9 patients (8 male, one female, mean age 59.3 years, range 48-75 years) with primary echinococcosis of skeletal muscles. The cysts presented as soft tissue masses in 8 patients, whereas in one, the cyst was an incidental finding on a CT scan performed for investigation of a lung problem. All hydatid cysts were confined into muscles, without affecting the bone. The location was the thigh region in 6 patients (quadriceps in 4, biceps in 2), the popliteal fossa (gastrocnemius) in one, the humerus (triceps branchii) in one and the shoulder (infraspinatus) in one patient. MRI showed multi-vesicular cysts in all patients. Indirect hemagglutination serological test was positive in 6 out of 9 cases. En block surgical excision of the cysts was undertaken in all patients. Two patients received antihelminthic chemotherapy preoperatively. Histopathologic findings confirmed the diagnosis. No recurrence occurred during the follow-up period (1-8 years). Skeletal muscle echinococcosis should be considered in the differential diagnosis of limb masses, especially in endemic countries. A meticulous history taking and MRI imaging are essential, while pericystectomy is an effective method of treatment. PMID:20596270

Laparoscopic Decortication of Hilar Renal Cysts Using LigaSure  

PubMed Central

Background and Objectives: In this study, we evaluated the safety and efficacy of using the LigaSure sealing system (Valleylab, Boulder, Colorado) for laparoscopic decortication of symptomatic hilar renal cysts. Methods: Seventeen patients underwent laparoscopic decortication of hilar renal cysts with the LigaSure system. Our study included only symptomatic, Bosniak type 1, simple and symptomatic renal cysts. The operative route, transperitoneal or retroperitoneal, was planned according to the location confirmed by computed tomography. The patients' symptoms were preoperatively and postoperatively evaluated by the Wong-Baker visual pain scale. Operative measures and radiologic outcomes were prospectively evaluated. Results: The mean age of the patients was 56.4 years, and the mean follow-up period was 12.5 months. Preoperative computed tomography showed only a single cyst in 15 patients (88.2%) and showed two separate cysts in 2 cases (11.8%). The cysts were located in the perihilar region close to the vascular structure in all patients. A transperitoneal approach was used in 9 patients, and a retroperitoneal approach was used in 8 patients. The mean operative time and hospitalization time were 56.4 minutes and 1.2 days, respectively. Minor complications were observed in 3 patients. Symptomatic and radiologic success rates of 94.2% and 100%, respectively, were achieved. Conclusion: Laparoscopic decortication of symptomatic hilar renal cysts—first reported in the literature in this study—using the LigaSure sealing system is feasible, effective, and safe, even if the cyst is located in the perihilar area.

Tailgut cysts: MRI findings.  

PubMed

Magnetic resonance imaging (MRI) features of 11 surgically resected pelvic tailgut cysts were analyzed with reference to histopathologic and clinical data. Homogeneity, size, location, signal intensity, appearance and presence of septa and/or nodules and/or peripheral rim and involvement of surrounding structures were studied. Histological examination demonstrated 11 tailgut cysts (TGC), including one infected TGC and one TGC with a component of adenocarcinoma. Lesions (3-8 cm in diameter) were exclusively or partly retrorectal in all cases but one, with an extension down the anal canal in five cases. Lesions were multicystic in all patients but one. On T1-weighted MR images, all cystic lesions contained at least one hyperintense cyst. The peripheral rim of the cystic lesion was regular and non or moderately enhancing in all cases but the two complicated TGC. Nodular peripheral rim and irregular septa were seen in the degenerated TGC. Marked enhancement of the peripheral structures was noted in the two complicated TGC. Pelvic MRI is a valuable tool in the preoperative evaluation of TGC. PMID:18566821

Odontogenic Keratocyst Mimicking Paradental Cyst  

PubMed Central

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

Invasive thyroglossal duct cyst papillary carcinoma: a case report  

PubMed Central

Introduction A thyroglossal duct cyst is the most common congenital anomaly of the thyroid gland and midline masses in childhood (70% abnormality in childhood, 7% in adult). Carcinomas arising from a thyroglossal duct cyst are rare (only 1% of thyroglossal duct cyst cases) and characterized by relatively non-aggressive behavior and rare lymphatic spread. They are also diagnosed mostly during the third and fourth decades of life. About 85% to 92% of all thyroglossal duct cyst carcinomas are papillary carcinomas. Case presentation We present the case of a 44-year-old Iranian woman with Cacausian ethnicity with a painless anterior neck mass that appeared gradually over three months. She had a history of frequent painful swelling of the anterior part of her neck, which subsided with antibiotic therapy. Thyroid functional tests were normal and a thyroid scinitigraphy showed a cold nodule in the left lobe of her thyroid. A computed tomography scan revealed a large, heterogeneous enhancing soft tissue mass with cystic components in the midline of the anterior neck space. This extended from the base of the tongue,(completely separated from its muscles, to the inferior aspect of the thyroid gland and showed the destruction of the hyoid bone and the thyroid cartilage. The diagnosis of a thyroglossal duct cyst with malignant transformation was maintained. A fine needle aspiration revealed papillary carcinoma. Conclusion This patient's case is presented because of its rare, aggressive, and invasive nature and rare and unusual manifestation, as well as its rapid increase in size, the destruction of the hyoid bone, chondrolysis of the thyroid cartilage, lymph adenopathy and the existence of a cold nodule in the thyroid gland.

Blake's pouch cyst  

PubMed Central

Background: In 1900, Joseph Blake described a transient posterior evagination of the tela choroidea of the fourth ventricle in the normal 130-day old human embryo. He was the first to recognize and fully elucidate on the real nature of the foramen of Magendie as an aperture, which develops within a saccular expansion of the embryonic fourth ventricular cavity. The persistence of this temporary fourth ventricular outpouching into the postnatal period and its significance either as separate entity or as an entity within the Dandy–Walker continuum has over the years been one of the most controversial topics in both neurosurgical and neuroradiological literature. Methods: A search of the medical literature was conducted for publications addressing the historical, embryological, and neuororadiological features as well as the clinical presentation and management of persistent Blake's pouch. Results: The literature on the various features of Blake's pouch cyst has limited areas of consensus between various authors. Conclusion: Blake's pouch cyst is a rare entity that is thought to belong to the Dandy–Walker continuum. It has a variable clinical presentation and when symptomatic can be treated with an endoscopic third ventriculostomy or shunting. PMID:25101207

Adrenal rest presenting as a renal cyst. A case report.  

PubMed

The report presents a 42-year old female patient, in whom a cyst of the left kidney was diagnosed. The clinical presentation and gross picture suggested a simple cyst. The lesion was removed surgically; in the cyst wall, histology revealed structures identical to normal adrenal cortex. Based of this observation, the final diagnosis was established as the so-called adrenal rest. Such lesions are not uncommon in the kidney, but what was extraordinary in the described case was the macroscopic presentation. Thus, in differential diagnosis of cystic lesions of the kidney one should also take into consideration adrenal developmental abnormalities. This may be of particular importance in cystic clear cell renal carcinomas, the structure of which is well known to resemble the adrenal cortex. PMID:14998297

Challenges in imaging and histopathological assessment of a giant cell tumour with secondary aneurysmal cyst in the patella.  

PubMed

The patella is an uncommon site for all primary and metastatic bone tumours and primary intra-osseous tumours of the patella are very rare. A majority of the patella tumours are benign. We report a patient with a sudden onset swelling and pain of the right knee following a staircase fall. The plain radiograph showed an expansile multiseptated patella lesion and it was further assessed with an MRI. The radiological findings and the initial histopathological features from a limited sample were suggestive of a primary aneurysmal bone cyst. However, the final histopathological diagnosis from a more adequate specimen was a giant cell tumour with a secondary aneurysmal bone cyst. PMID:24057334

Spinal perineurial and meningeal cysts.  

PubMed

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

Lung cysts in chronic paracoccidioidomycosis*  

PubMed Central

On HRCT scans, lung cysts are characterized by rounded areas of low attenuation in the lung parenchyma and a well-defined interface with the normal adjacent lung. The most common cystic lung diseases are lymphangioleiomyomatosis, Langerhans cell histiocytosis, and lymphocytic interstitial pneumonia. In a retrospective analysis of the HRCT findings in 50 patients diagnosed with chronic paracoccidioidomycosis, we found lung cysts in 5 cases (10%), indicating that patients with paracoccidioidomycosis can present with lung cysts on HRCT scans. Therefore, paracoccidioidomycosis should be included in the differential diagnosis of cystic lung diseases. PMID:23857700

[Differential diagnosis of children's enlarged necks--cervical thymic cysts].  

PubMed

We present a cervical thymic cyst in an otherwise healthy 11 year old boy. Ultrasonography revealed a smooth, medium echogenic cystic mass of 62 x 28 x 12 mm with weak acoustic enhancement lying between the carotid artery and the internal jugular vein. The mass extended from the hyoid bone to the inferior pole of the thyroid gland. CT scans also revealed the displacement of the carotid artery and the internal jugular vein by an atypically dense cystic mass. At operation the vagus nerve had to be dissected from the posterior wall of the cyst. A solid band of fibrous tissue extended to the inferior pole of the thyroid gland; there was no connection to the pharyngeal wall. On histological examination Hassal's bodies, cholesterol crystals and a mild round-cell infiltration were observed. The postoperative course was normal. There were no immune defects or signs of lymphogranulomatous disease. Cervical thymic cysts may be recognised before operation and differentiated from second arch cysts by their atypically low infrahyoid position, their intimate relation to the vessels of the neck and their extension into the upper mediastinum. Surgery can be difficult due to the intimate relation to the vessels of the neck and the vagus nerve, and to extension into the upper mediastinum. PMID:1568889

Minimally Invasive Excision of Epidermal Cysts through a Small Hole Made by a CO2 Laser  

PubMed Central

To improve the cosmetic results of removing epidermal cysts, minimally invasive methods have been proposed. We proposed a new minimally invasive method that completely removes a cyst through a small hole made by a CO2 laser. Twenty-five patients with epidermal cysts, which were 0.5 to 1.5 cm in diameter, non-inflamed, and freely movable, were treated. All of the patients were satisfied with the cosmetic results. This method is simple and results in minimal scarring and low recurrence rates without complications. PMID:24511501

A Large Proliferating Trichilemmal Cyst Masquerading as Squamous Cell Carcinoma  

PubMed Central

Proliferating trichilemmal cyst (PTC), a rare benign tumor, is a fascinating follicular neoplasm. It occurs on head and neck region of elderly women and its histologic hallmark is trichilemmal keratinization. A 70-year-old female presented to skin outpatient department with complaints of a slowly growing mass on scalp for the past 2 years. On examination, the lesion was firm, mobile, painless, and measured 6 × 5 × 3 cm and was not fixed to the underlying bone. Laboratory investigations were unremarkable. Excisional biopsy was done. Histopathology revealed well-demarcated tumor with variably sized lobules of squamous epithelium undergoing an abrupt change into eosinophilic amorphous keratin without granular cell layer (trichilemmal keratinization). PTC should be differentiated from trichilemmal cyst as it has potential for malignant transformation. Thus, complete excision is recommended for all benign proliferating variants owing to their potential for locally aggressive behavior and malignant transformation.

Morphologic alterations of the subchondral bone in advanced degenerative arthritis.  

PubMed

A series of 535 femoral heads surgically excised at the time of total hip arthroplasty for degenerative arthritis were analyzed by gross photography, specimen roentgenograms, and whole-mount histologic sections. Limited regenerative capacity was apparent in the chondrous tufts in the exposed bone of the osteoarthritic joint surface. The mechanism for the formation of subchondral cysts was interpreted to be the proliferation of viable myxomatous cells within the bone marrow. Osseous remodeling adjacent to the cysts was secondary to expansion of the soft tissue contents of the early cysts and later vascularization with fibrosis in the older cysts. Stress fracturing was a focal feature secondary to the remodeling of live bone. Advanced degenerative arthritis demonstrated focal osteocytic necrosis in the exposed osseous surface. Bone necrosis was also observed when small segments of the surface were undermined by cysts. Finally, bone necrosis was occasionally observed as focal infarcts of the joint surface (2-6 mm). In all three instances, bone necrosis in degenerative arthritis appeared to be a secondary reaction, presumably related to local disruption of blood supply. PMID:6825342

Laparoscopic approach to retrorectal cyst.  

PubMed

Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomograghy (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space. PMID:19030218

Bone disease in primary hyperparathyroidism  

PubMed Central

Bone disease in severe primary hyperparathyroidism (PHPT) is described classically as osteitis fibrosa cystica (OFC). Bone pain, skeletal deformities and pathological fractures are features of OFC. Bone mineral density is usually extremely low in OFC, but it is reversible after surgical cure. The signs and symptoms of severe bone disease include bone pain, pathologic fractures, proximal muscle weakness with hyperreflexia. Bone involvement is typically characterized as salt-and-pepper appearance in the skull, bone erosions and bone resorption of the phalanges, brown tumors and cysts. In the radiography, diffuse demineralization is observed, along with pathological fractures, particularly in the long bones of the extremities. In severe, symptomatic PHPT, marked elevation of the serum calcium and PTH concentrations are seen and renal involvement is manifested by nephrolithiasis and nephrocalcinosis. A new technology, recently approved for clinical use in the United States and Europe, is likely to become more widely available because it is an adaptation of the lumbar spine DXA image. Trabecular bone score (TBS) is a gray-level textural analysis that provides an indirect index of trabecular microarchitecture. Newer technologies, such as high-resolution peripheral quantitative computed tomography (HR-pQCT), have provided further understanding of the microstructural skeletal features in PHPT. PMID:25166047

Do Renal Cysts Affect the Success of Extracorporeal Shockwave Lithotripsy? A Retrospective Comparative Study  

PubMed Central

The aim of this study was to assess the effect of simple renal cysts on extracorporeal shockwave lithotripsy (SWL) in patients with calyceal renal calculi. Patients with simple renal cysts >35?mm and ipsilateral renal calculi <20?mm that were treated with SWL constituted group 1 (cyst + calculi). The control group included patients aged >40 years that had renal calculi <20?mm and no cysts that were treated with SWL. The 2 groups were compared according to age, gender, body mass index, calculi size, localization, and density, the calculi fragmentation rate, and the percentage of stone-free patients. Mean cyst size in group 1 was 44.04 ± 9.08?mm. Mean age in group 1 was 61.4 ± 10.2 years versus 56.9 ± 8.2 years in the control group; the difference was significant (P = 0.045). There were not any other significant differences between the 2 groups, except for the stone-free rate (P > 0.05), which was 33.3% in group 1 and 68.2% in the control group (P = 0.017). The presence of renal cysts in a patient with calculi requires that an individualized treatment plan be devised, so as to provide the patient with the most effective treatment. PMID:23840202

Pigmented eyelid cysts revisited: apocrine retention cyst chromhidrosis.  

PubMed

A minority of eyelid hidrocystomas are pigmented containing brown-black contents. Chromhidrosis describes the excretion of colored secretions composed of lipofuscin pigments in apocrine gland-rich anatomic locations. The objective of this study is to evaluate the clinicopathologic features of pigmented eyelid cysts. A case-control study was conducted, examining consecutive pigmented and nonpigmented eyelid hidrocystoma excision specimens. Over a 4-year period, 9 pigmented eyelid hidrocystomas were identified, representing 13% (9/70) of all hidrocystoma excisions. Compared to controls (n = 14), no difference existed for age [mean age 59 (44-78 years) vs. 60 (42-82 years)] or size [mean diameter 2.3 (1-4 mm) vs. 2.7 (1-5 mm)] (pigmented vs. nonpigmented, respectively), but a trend for female, left side, and lower lid predominance for pigmented hidrocystomas existed: 8:1 versus 7:7 F:M; 7:2 versus 7:7 left:right; 8:1 versus 9:5 lower:upper eyelid (pigmented vs. nonpigmented, respectively). Clinically, the pigmented cysts' color varied from dark blue, brown, and to black, and on gross examination, they expressed dark brown to black granular liquid contents. Applying histologic criteria of Jakobiec and Zakka, 8 of 9 and 14 of 14 pigmented and nonpigmented hidrocystomas were of apocrine type. Seven of 9 (78%) pigmented cysts and 6 of 14 (43%) nonpigmented hidrocystomas contained granular eosinophilic cyst contents and/or intracellular cytoplasmic granular pigmented deposits by light microscopy. (The pigmented cyst contents did not survive processing in 2 cases.) By histochemistry (periodic acid Schiff with diastase, Sudan Black, and Fite acid-fast positive staining) and ultraviolet fluorescence, these sediments were determined to be lipofuscin pigments. No hidrocystomas had melanin deposits, and one case had hemosiderin deposits in a scarred cyst wall in addition to cyst lipofuscin pigments. In studies of chromhidrosis, both normal and chromhidrotic apocrine glands contain lipofuscin pigments; the sole difference lies in the amount of lipofuscin granules. Similarly, for eyelid apocrine hidrocystomas, lipofuscin pigments exist in both groups. Presumptively, the amount of lipofuscin and degree of its oxidation distinguish pigmented from nonpigmented apocrine hidrocystomas. PMID:24247572

Pericyst: the outermost layer of hydatid cyst.  

PubMed

Hydatid disease, caused by the parasite Echinococcus granulosus, mostly affects the liver and the lungs with hydatid cysts which consist of three layers: (1) the outer pericyst; (2) the middle laminated membrane; and (3) the inner germinal layer. Pericyst, as the outermost layer of the hydatid cyst, is made by host cells encasing the hydatid cyst. An extremely close interaction exists between this host tissue and the parasite, and any degenerative changes of the pericyst would result in hydatid cyst degeneration or rupture. The pericyst plays an undeniably important role in the development and survival of the hydatid cyst. PMID:24574815

Prenatal diagnosis of a paraurethral cyst.  

PubMed

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

Radiculopathy due to spontaneous facetal cyst hemorrhage  

PubMed Central

Facetal cysts are usually encountered as incidental radiological findings in spinal imaging studies. Only rarely can neurological symptoms be attributed to them. These cysts are lined by vascularized synovial tissue. There are few reports in literature of hemorrhagic transformation in these cysts with sudden increase in size precipitating symptoms acutely. We report one such case where the existence of a hitherto undiagnosed cyst was unmasked by the haemorrhage. There is a need to be aware of this complication in patients with untreated or incidentally diagnosed cysts so that any sudden neurological deterioration can be dealt with promptly.

How to Build a Simple and Safe Laparoscopic Hydatid Evaluation System  

PubMed Central

Background: One of the most common problems faced in laparoscopic treatment of hydatid cysts is the difficulty in evacuating the particulate contents (daughter cysts and laminated membrane). Although various instruments and laparoscopic techniques have been described to evacuate the contents of hydatid cysts, most are not available at many surgical centers. Methods: By assembling disposable, cheap, and available anesthesia equipment with common laparoscopic instruments, a laparoscopic system was made to evacuate the contents of a hydatid cyst. Ten patients with hepatic hydatid disease underwent laparoscopic surgery using this new hydatid system between June 2011 and January 2013. Results: The procedure was completely straightforward. Twelve hydatid cysts (2 patients had 2 separated cysts) were evacuated without any spillage. All patients were followed for at least 8 months, with no evidence of recurrence. Conclusions: This simple apparatus, which can be assembled anywhere, was safely used to evacuate the contents of hydatid cysts without causing any spillage. PMID:25392637

A case of symptomatic Rathke's cyst  

PubMed Central

Rathke's cleft cyst is a benign growth found on the pituitary gland in the brain, specifically a fluid-filled cyst in the posterior portion of the anterior pituitary gland. It occurs when the Rathke's pouch does not develop properly, and ranges in size from 2 to 40?mm in diameter. Asymptomatic cysts are common, detected during autopsies of 2–26% of individuals who have died of unrelated causes. Symptomatic cysts are rare and only approximately 150 cases have been reported. Females are twice as likely as males to have a cyst. Symptomatic cysts can trigger visual disturbances, pituitary dysfunction and headaches. Here we present a case of a 40-year-old female patient who presented with complains of visual disturbances, headache and amenorrhoea. On investigations, MRI of brain revealed findings suggestive of Rathke's cleft cyst. PMID:23355555

Multidirectional Instability Accompanying an Inferior Labral Cyst  

PubMed Central

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

Intratesticular Epidermoid Cyst Masquerading as Testicular Torsion  

PubMed Central

Epidermoid cysts are benign tumors that comprise approximately 1% of all testicular masses. They usually present as painless masses that can be identified on scrotal ultrasound as well-demarcated intratesticular lesions with mixed echogenicity. This case report describes a rare presentation of an extremely large intratesticular epidermoid cyst with clinical and radiologic findings more consistent with testicular torsion. The sizeable cyst obliterated the surrounding testicular parenchyma, causing it to appear on scrotal Doppler ultrasound as a testicle devoid of blood flow. This obliteration also resulted in failure to identify a testicular mass on physical examination or imaging. The current literature contains previous reports of extratesticular epidermoid cysts presenting as torsion; however, this is the first report of an intratesticular epidermoid cyst presenting in this manner. Though smaller cysts may be managed effectively with testicular-sparing surgery, optimal management of a cyst this size requires orchiectomy.

Sacral perineural cyst mimicking inflammatory low back pain.  

PubMed

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.

New insights about suprapatellar cyst.  

PubMed

Suprapatellar bursa is located between the quadriceps tendon and femur, and it develops before the birth as a separate synovial compartment proximal to the knee joint. By the fifth month of fetal life there is a suprapatellar septum between the knee joint cavity and suprapatellar bursa which later perforates and involutes in a way that a normal communication between the cavity of bursa and knee is established. A small portion of the embrionic septum can later lag as more or less expressed suprapatellar plica. In case when suprapatellar plica has a small communication with valve mechanism or in case of complete septum, bursa becomes a separate compartment and potential location for the suprapatellar cyst development. Magnetic resonance imaging is recognised as the gold standard in diagnosis of knee cysts because of its ability to show cystic nature of the lesion, its relationship with other anatomic structures, as well as to establish whether other knee pathologies are present. Considering treatment possibilities, majority of cysts around the knee resolve spontaneously and should be treated by aspiration and application of corticosteroids. Suprapatellar cyst is a very rare knee pathology and it can in some occasions be treated using open or arthroscopic surgery. PMID:22577510

[Hydatid cysts of the liver].  

PubMed

Single or multiple hydatid cysts of the liver are frequently observed in Italy and the Mediterranean countries. They are swellings caused by the hexacanth larva of a small cestode, Echinococcus granulosus. This must be distinguished from E. multilocularis, which is responsible for alveolar cyst, and is common in central-eastern Europe, but rare in Italy. An account is given of the development cycle of the intermediate and final host, the protean symptomatology (dependent on the siting of the cyst in the liver and the presence of complications), and the radiological, ultrasound, biological and anatomical diagnosis of this form. Diagnosis is much dependent on the examinations of first choice (currently echotomography, plus immunoelectrophoresis and immunofluorescence that permit epidemiological control of the community and serological follow-up after surgery). Computed tomography is of assistance in the approximately 25% of cases in which echotomography is not conclusive, while angiography is called upon to provide very precise mapping of the supramesocolic region. Surgery requires two fundamental stages: sterilisation of the parasite and treatment of the pericystium. It involves external or internal shunting, or partial or total resection, depending on various factors, particularly the thinness or thickness of the pericystium, the absence or presence of infection, and the site, volume and number of the cysts. Medical management with mebendazole and its derivatives is still chancy, both on the strictly therapeutic plane and with regard to the prevention of secondary, spontaneous or postoperative dissemination.

Spinal endodermal cyst resembling an arachnoid cyst in appearance: Pitfalls in intraoperative diagnosis of cystic lesions  

PubMed Central

Background: Surgical treatment of endodermal cysts requires total removal of the cyst wall during the first operation to prevent recurrence. Therefore, intraoperative pathological diagnosis plays an important role in determining the optimal surgical strategy. We present a rare case of a spinal endodermal cyst and discuss its diagnostic difficulty during the intraoperative pathological examination. Case Description: An 18-year-old male presented with progressive paraparesis and precordial oppression. Magnetic resonance (MR) imaging revealed an intradural extramedullary cystic mass having the same signal intensity as cerebrospinal fluid (CSF) without gadolinium enhancement at the T1-T2 level. The preoperative diagnosis was an endodermal or arachnoid cyst. The patient underwent surgery. An intraoperative frozen section showed a cyst wall consisting of loose, thin, fibrous tissue intermittently covered by flattened epithelium. The diagnosis was an arachnoid cyst. Accordingly, partial resection of the cyst wall was performed to create CSF communication between the cyst and subarachnoid space. However, the postoperative pathological diagnosis from permanent sections was an endodermal cyst, which was lined with ciliated columnar epithelium that was immunopositive for cytokeratin and epithelial membrane antigen. Subsequent paraffin embedding and immunostaining of the intraoperative frozen sample also confirmed patchy cytokeratin expression by all flattened epithelial cells. The patient's cyst had refilled 10 months after surgery, and he subsequently underwent fenestration of the cyst wall and placement of a cyst-subarachnoid shunt. Conclusion: Examination of multiple samples from multiple sites or intraoperative immunostaining of frozen sections is recommended for accurate intraoperative diagnosis of endodermal cysts.

Eosinophilic granuloma presenting as an epidural hematoma and cyst.  

PubMed

Langerhans' cell histiocytosis (LCH) is a rare immunologic disorder characterized by histiocyte proliferation in multiple organ systems. Eosinophilic granuloma, a benign bone lesion, represents a focal form of LCH. We experienced a case of Langerhans' cell histiocytosis in a patient who presented with intracranial epidural hematoma and cyst on the midline of the frontal skull. A 10-year-old boy presented with a rapidly growing large scalp mass on the midline frontal area after mild head trauma. The scalp mass was painless and immobile. Plain skull x-ray showed a punched-out bone lesion. Computed tomography and magnetic resonance imaging showed a non-enhancing osteolytic lesion presenting with an epidural hematoma and cyst on the midline of the frontal skull. The lesion of the skull was completely resected and the patient's recovery was uneventful. The acute presentation of a solitary eosinophilic granuloma of skull with an epidural hematoma has been described in only five cases in the literature and we report the first case of LCH presenting as an intracranial epidural hematoma on frontal area.

Boiling sheep liver or lung for 30 minutes is necessary and sufficient to kill Echinococcus granulosus protoscoleces in hydatid cysts  

PubMed Central

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

In one case, a parous lady presented with an adnexal mass and D/D of broad ligament fibroid or ovarian mass was considered which turned out to be a cyst containing cheesy pultaceous material. In the other case, a parous lady presented with a mass arising from the posterior fourchette that contained cheesy pultaceous material on excision. In both cases histopathology confirmed it to be epidermal cysts. Epidermal cysts known for its rare incidence by itself is now found to be presenting at rare sites which emphasizes on the need for further research into the etiopathogenesis of these cysts and its development at the various sites of the body.

Videothoracoscopy in the treatment of mediastinal cysts  

PubMed Central

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

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 ?g/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 ?g 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.

Ginkgolide B inhibits renal cyst development in in vitro and in vivo cyst models  

PubMed Central

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disease characterized by massive enlargement of fluid-filled cysts in the kidney. However, there is no effective therapy yet for this disease. To examine whether ginkgolide B, a natural compound, inhibits cyst development, a Madin-Darby canine kidney (MDCK) cyst model, an embryonic kidney cyst model, and a PKD mouse model were used. Interestingly, ginkgolide B significantly inhibited MDCK cyst formation dose dependently, with up to 69% reduction by 2 ?M ginkgolide B. Ginkgolide B also significantly inhibited cyst enlargement in the MDCK cyst model, embryonic kidney cyst model, and PKD mouse model. To determine the underlying mechanisms, the effect of ginkgolide B on MDCK cell viability, proliferation, apoptosis, chloride transporter CFTR activity, and intracellular signaling pathways were also studied. Ginkgolide B did not affect cell viability, proliferation, and expression and activity of the chloride transporter CFTR that mediates cyst fluid secretion. Ginkgolide B induced cyst cell differentiation and altered the Ras/MAPK signaling pathway. Taken together, our results demonstrate that ginkgolide B inhibits renal cyst formation and enlargement, suggesting that ginkgolide B might be developed into a novel candidate drug for ADPKD.

Hydatid cyst: unusual presentation as 'breast lump'.  

PubMed

Hydatid cyst in the breast is rare. We report a case of hydatid cyst in the breast in a 30-year-old Indian rural woman who presented with a lump in her left breast. MRI findings showed a cystic lesion in the breast. Histopathological examination showed features consistent with hydatid cyst with surrounding adherent pericystic breast tissue showing fibrocollagenisation and inflammatory response. ELISA for echinococcal antigen was also found to be positive. This case emphasises that preoperative diagnosis of hydatid cyst in the breast is difficult and often missed as the breast is a rare site of echinococcal infection and clinical and imaging findings are wide and non-specific. Cytological diagnosis by fine-needle aspiration may not always be possible. Therefore, hydatid cyst in the breast should always be considered in the differential diagnosis of a breast lump and histopathological confirmation is necessary for early and appropriate treatment.

Primary cervical hydatid cyst: a rare occurrence  

PubMed Central

Hydatid disease, a parasitic infection is caused by Echinococcus granulosus. It has serious impact on health and economy especially in countries where it is endemic. It occurs frequently in liver and lung. The disease is chronic and cyst can localize in different organs. A hydatid cyst occurrence in the head and neck is extremely rare. To know the distribution of disease can help in its control and prevention. We report a case of primary cervical hydatid cyst in 20 year old female. A high index of suspicion is required to diagnose hydatid cyst in rare locations like this. Hydatid cyst should be considered in differential diagnosis of benign swellings of head and neck region, so that it can be managed during surgery to prevent acute anaphylaxis.

Endoscopic Transsphenoidal Cisternostomy for Nonneoplastic Sellar Cysts  

PubMed Central

Background and Importance. Sellar arachnoid cysts and Rathke's cleft cysts are benign lesions that produce similar symptoms, including optochiasmatic compression, pituitary dysfunction, and headache. Studies have reported the use of various surgical treatment methods for treating these symptoms, preventing recurrence, and minimizing operative complications. However, the postoperative cerebrospinal fluid (CSF) fistula and recurrence rate remain significant. Clinical Presentation. In this paper, we present 8 consecutive cases involving arachnoid cysts and Rathke's cleft cysts, which were managed by using drainage and cisternostomy, the intentional fenestration of the cyst into the subarachnoid space, and then meticulously closing sellar floor using dural sutures. The postoperative images, CSF fistula rate, and the recurrence rate were favorable. Conclusion. We report this technique and discuss the benefit of this minimally invasive approach.

Chylous mesenteric cysts: a rare surgical challenge  

PubMed Central

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.

Sacral perineural cyst accompanying disc herniation.  

PubMed

Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

Cervicofacial actinomycosis mimicking sebaceous cyst  

PubMed Central

Actinomycosis is a rare, torpid, suppurative and chronic granulomatous infection caused by a Gram-positive organism that was initially thought to be a fungus. These organisms normally live as commensals in the human oral cavity, respiratory and digestive tracts, but become invasive when they gain access to the subcutaneous tissue through a musosal lesion, the triggering events being dental caries, dental manipulation and maxillofacial trauma. It is often misdiagnosed as it can mimic numerous infectious and non-infectious diseases. We describe an interesting case of cervical actinomycosis that was misdiagnosed as sebaceous cyst and precisely identified after histopathological examination of the tissue. PMID:23417945

Strategies To Discover the Structural Components of Cyst and Oocyst Walls  

PubMed Central

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, ?-1,3-linked glucose for Toxoplasma, and ?-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 ?-1,3-GalNAc polymer and lectins that bind the polymer (Giardia). Oocyst walls of Toxoplasma have two distinct layers that resemble those of fungi (?-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

Soybean cyst nematode effects on soybean aphid preference and performance in the laboratory.  

PubMed

Herbivores on plants frequently interact via shared resources. Studies that have examined performance of herbivores in the presence of other herbivores, however, have often focused on above-ground feeding guilds and relatively less research has examined interactions between below- and above-ground consumers. We examine how soybean aphid, Aphis glycines (Matsumura) an above-ground phloem-feeding herbivore, interacts with a below-ground plant parasite, soybean cyst nematode, Heterodera glycines (Ichinohe) through their shared host plant, soybean (Glycine max L). Laboratory experiments evaluated the preference of alate (flight-capable) soybean aphids toward plants either infected with soybean cyst nematode or uninfected controls in a simple choice arena. Alate soybean aphids preferred uninfected soybean over soybean cyst nematode-infected plants: 48 h after the releases of alate aphids in the center of the arena, 67% more aphids were found on control soybean compared with nematode infected plants. No-choice feeding assays were also conducted using clip cages and apterous (flight-incapable) aphids to investigate effect of soybean cyst nematode infection of soybean on aphid performance. These studies had mixed results: in one set of experiments overall aphid population growth at 7 d was not statistically different between control and soybean cyst nematode-infected plants. A different experiment using a life-table analysis found that apterous aphids feeding on soybean cyst nematode-infected plants had significantly greater finite rate of increase (?), intrinsic rate of increase (r(m)), and net reproductive rate (R(o)) compared with aphids reared on uninfected (control) soybean plants. We conclude that the below-ground herbivore, soybean cyst nematode, primarily influences soybean aphid behavior rather than performance. PMID:22546453

The predominant bacteria isolated from radicular cysts  

PubMed Central

Purpose To detect predominant bacteria associated with radicular cysts and discuss in light of the literature. Material and methods Clinical materials were obtained from 35 radicular cysts by aspiration. Cultures were made from clinical materials by modern laboratory techniques, they underwent microbiologic analysis. Results The following are microorganisms isolated from cultures: Streptococcus milleri Group (SMG) (23.8%) [Streptococcus constellatus (19.1%) and Streptococcus anginosus (4.7%)], Streptococcus sanguis (14.3%), Streptococcus mitis (4.7%), Streptococcus cremoris (4.7%), Peptostreptococcus pevotii (4.7%), Prevotella buccae (4.7%), Prevotella intermedia (4.7%), Actinomyces meyeri (4.7%), Actinomyces viscosus (4.7%), Propionibacterium propionicum (4.7%), Bacteroides capillosus (4.7%), Staphylococcus hominis (4.7%), Rothia denticariosa (4.7%), Gemella haemolysans (4.7%), and Fusobacterium nucleatum (4.7%). Conclusions Results of this study demonstrated that radicular cysts show a great variety of anaerobic and facultative anaerobic bacterial flora. It was observed that all isolated microorganisms were the types commonly found in oral flora. Although no specific microorganism was found, Streptococcus spp. bacteria (47.5%) – especially SMG (23.8%) – were predominantly found in the microorganisms isolated. Furthermore, radicular cysts might be polymicrobial originated. Although radicular cyst is an inflammatory cyst, some radicular cyst fluids might be sterile. PMID:24011184

Esophageal duplication cyst containing a foreign body  

PubMed Central

About 10% to 15% of all duplication cysts in the alimentary tract are esophageal. Esophageal duplication cysts are intimately attached to the alimentary tract, are lined by mucous membrane and have smooth muscle. This paper describes a 2-year-old child who presented with symptoms of progressive respiratory distress. A diagnosis of esophageal duplication cyst was made. At surgery a low cervical incision was made and the sternal manubrium split, thereby providing adequate exposure. The cyst was then removed. The most useful investigations were chest roentgenography and barium esophagography. Computerized tomography showed a small, round foreign body in the middle of the cyst that was subsequently found to be a bingo chip. Communication between the cyst and the esophagus was not obvious at the time of surgery and had not been demonstrated by barium esophagography. When complete excision of the cyst is not possible because of inflammatory reaction all the mucosa must be removed to prevent recurrence. Careful postoperative respiratory support and broad-spectrum antibiotic therapy are recommended. ImagesFig. 1Fig. 2Fig. 3 PMID:3971270

Symptomatic and complicated nonhereditary developmental liver cysts: cross-sectional imaging findings.  

PubMed

Commonly encountered in the general population, in the vast majority of cases nonhereditary developmental liver cysts are asymptomatic, not associated with altered hepatic function and confidently diagnosed on imaging studies, and do not require further workup, follow-up, or treatment. However, particularly in women, simple hepatic cysts may reach large sizes and cause symptoms and signs resulting from mass effect, vascular compression, and biliary obstruction. Furthermore, although rarely compared to the incidence observed in patients with adult polycystic kidney and liver disease, sporadic hepatic cysts sometimes undergo life-threatening complications such as intracystic hemorrhage, infection, or rupture, which require prompt imaging triage and appropriate interventional, laparoscopic, or open surgical treatment. This pictorial essay reviews with examples the cross-sectional imaging findings of symptomatic and complicated nonhereditary liver cysts, aiming to provide radiologists with an increased familiarity with these uncommon, challenging occurrences. Emphasis is placed on the role of MRI as a useful problem-solving modality to elucidate the complex imaging appearances resulting from intracystic bleeding and superinfection, and to differentiate complicated cysts from other hemorrhagic liver lesions and biliary cystic tumors.

Primary intraosseous carcinoma arising from an odontogenic cyst: A case report  

PubMed Central

Cyst-like lesions in the mandible rarely develop into malignancies, and the reported incidence is between 0.3 and 2%. The present study describes a rare case of primary intraosseous squamous cell carcinoma of the mandible arising from an odontogenic cyst. A 59-year-old female was referred to Asahi University Murakami Memorial Hospital (Gifu, Japan), with acute pain in the right molars. An initial examination revealed buccal swelling and paresthesia of the mental nerve. Following an intraoral examination, the oral mucosa was confirmed to be normal, however, percussion pain was experienced between the lower right first premolar and second molar. Panoramic radiography revealed a retained lower right wisdom tooth and an irregular radiolucent area between the lower right molar and a mandibular angle with unclear margins. Computed tomography revealed diffuse bone resorption and an extensive loss of cortical bone on the buccal and lingual sides. A biopsy was performed and the pathological diagnosis was of a squamous cell carcinoma arising from the epithelial lining of the odontogenic cyst. Radical dissection was subsequently performed, however, histopathological examination of the resected specimen revealed neither invasion into the surrounding tissues penetrating the periosteum nor lymph node metastasis at the right submandibular lesion. Following the pathological diagnosis of primary intraosseous carcinoma (PIOC), the patient received 6,000 Gy radiation as post-operative radiotherapy and chemotherapy with oral administration of tegafur, gimeracil and oteracil potassium. The patient is currently undergoing follow-up examinations. Although PIOC arising from an odontogenic cyst is rare, it should be considered as a differential diagnosis for radiolucency of the jaw bone, particularly in older patients exhibiting a history of cystic lesions.

Spontaneous hepatic hydatid cyst rupture into the biliary tract is unusual. The authors describe a case of a 62-year-old man with a hepatic hydatid cyst, showing that it is possible to confirm rupture into the biliary system with cholangiography-MRI. Surgical treatment remains the best form of management. Endoscopic management is a therapeutic possibility in all cases in which surgery is contraindicated. In the case observed endoscopic sphinctererotomy resolved the biliary obstruction, while the hydatid cyst was treated by transbiliary irrigation with scolicidal solutions and pharmacological therapy. The treatment permitted complete clinical resolution of the hepatic hydatosis. PMID:12038119

Three species of fungi, Catenaria auxiliarls (Kühn) Tribe, Nematophthora gynophila Kerry and Crump, and a Lagenidiaceous fungus have been found attacking female cyst nematodes. All are zoosporic fungi which parasitize females on the root surface, cause the breakdown of the nematode cuticle, and prevent cyst formation. Their identification and some aspects of their biology are reviewed. N. gynophila is widespread in Britain and reduces populations of the cereal cyst nematode, Heterodera avenae Woll., to nondamaging levels.

Bone and bone turnover.  

PubMed

Children with cancer are exposed to multiple influences that may adversely affect bone health. Some treatments have direct deleterious effects on bone whilst others may have indirect effects mediated through various endocrine abnormalities. Most clinical outcome studies have concentrated on survivors of acute lymphoblastic leukaemia (ALL). There is now good evidence that earlier treatment protocols that included cranial irradiation with doses of 24 Gy or greater may result in growth hormone deficiency and low bone mineral density (BMD) in the lumbar spine and femoral neck. Under current protocols, BMD decreases during intensive chemotherapy and fracture risk increases. Although total body BMD may eventually return to normal after completion of chemotherapy, lumbar spine trabecular BMD may remain low for many years. The implications for long-term fracture risk are unknown. Risk factors for low BMD include high dose methotrexate, higher cumulative doses of glucocorticoids, male gender and low physical activity. BMD outcome in non-ALL childhood cancers has been less well studied but there is evidence that survivors of childhood brain or bone tumours, and survivors of bone marrow transplants for childhood malignancy, all have a high risk of long-term osteopenia. Long-term follow-up is required, with appropriate treatment of any endocrine abnormalities identified. PMID:19293605

Bronchogenic cysts are rare congenital anomalies result of abnormal development of the tracheobronchial tree. They develop in the lung parenchyma or in the mediastinum. For a period of 17 years (1975-1991) a total of 46 children with bronchogenic cysts have been treated; in 6 the cysts were localized in the mediastinum. Two patients were one-year-old, 3 were in the age group 1 to 3 years and 1 was older than 3 years. Four patients were boys and 2 girls. Two children had hacking cough and attacks of dyspnea; one had swallowing difficulties. In 3 children the disease produced no symptoms and was detected on examination for pneumonia (1 child) and acute upper respiratory tract infection (2 children). All children had conventional X-ray; 5 had esophagography as well, 4--computer axial tomography, 3--echography. All children were operated (total extirpation of the cyst) and left the hospital cured.

Neuroendoscopic Approach to Quadrigeminal Cistern Arachnoid Cysts  

PubMed Central

Objective: The introduction of neuroendoscopy has provided a minimally invasive modality for the surgical treatment of quadrigeminal arachnoid cysts. Three pediatric patients with arachnoid cyst of the quadrigeminal cistern treated by endoscopic fenestration are reported. Materials and Methods: The hospital records of patients were retrospectively rewieved. All patients had hydrocephalus. A lateral ventricle-cystostomy and endoscopic third ventriculostomy were performed by using rigid neuroendoscopes. Results: There were one boy and two girls with ages 7 months, 9 months and 14 years, respectively. One patient had undergone shunting prior to neuroendoscopic surgery. The postoperative course was uneventful in all cases, with no complications. They showed disappearance of intracranial hypertension symptoms and significant reduction of the cyst size. Conclusion: Neuroendoscopic technique is an effective and suitable method for the treatment of quadrigeminal cistern arachnoid cysts and accompanying hydrocephalus.

Intracerebral cysts and cystic appearing intracerebral masses are common findings at routine cerebral imaging examination. We discuss here the most interesting aspects of some intracerebral cysts encountered in medical practice in terms of imaging, clinical and pathological description, and problems of differential diagnosis. On an almost routine basis, the neurologists have to deal with such differentials. Therefore, we aim to mention here some of the frequently encountered diagnosis problems when a patient presents with a cystic cerebral mass. PMID:23737706

Gaint Epidermoid Cyst of External Ear– A Rare Case Report  

PubMed Central

Epidermoid cysts are developmental, benign, cutaneous cysts which are commonly found on face followed by trunk and neck. They account for approximately 80% of follicular cysts of the skin. They are slow growing lesions and remain asymptomatic until or unless secondarily infected. They occasionally have tendency to develop into a malignancy. We describe a case of giant epidermoid cyst of posterior part of external ear, a location where very few cases have been reported in the literature. Since cyst was attached to the external ear, esthetics was also one of the important concern apart from the cyst getting infected, as they cause disfigurement of the face. The cyst was excised surgically. Histopathology confirmed the presumptive diagnosis of Epidermoid cyst. Two-years after the resection there was no recurrence. Due to the possibility of the cyst to transform into a malignancy and for appropriate diagnosis, histopathological examination remains a gold standard for confirmatory diagnosis. PMID:24701521

Inflamed symptomatic sellar arachnoid cyst: case report.  

PubMed

Sellar arachnoid cysts are rare; an infected arachnoid cyst is extremely rare as only one case has been reported to date in the literature. Here, we report a patient with an infected or inflamed sellar arachnoid cyst that was successfully treated with transsphenoidal surgery (TSA). A 53-year-old female with a history of chronic sinusitis developed a headache 5 months ago, and one month before admission polyuria, polydipsia, and abnormal vaginal bleeding occurred. The magnetic resonance imaging (MRI) showed a sellar cystic mass with a thickened pituitary stalk. Preoperative hormonal study revealed normal pituitary hormone levels except for a moderate elevation of prolactin. She was diagnosed with diabetes insipidus of the central nervous system origin based on a water-deprivation test. TSA was performed under an impression of symptomatic Rathke's cleft cyst according to the MRI findings. Intraoperative findings showed confirmation of turbid intracystic contents, but micro-organisms were unidentified on microbial culture. Pathology of the cyst wall revealed inflamed meningoepithelial lining cells compatible with an arachnoid cyst. PMID:24904886

Residual Cyst Associated with Calcifications in an Elderly Patient  

PubMed Central

A residual cyst, as the name implies, is a radicular, lateral periodotal, dentigerous or any other cyst that has persisted after it’s associated tooth has been lost. Residual cysts show more predilection in males and they commonly affect the maxillary region. Usually, residual cysts are asymptomatic and calcifications occurring in the residual cysts are quite rare. We are reporting a case of symptomatic residual cyst, associated with calcifications involving the anterior region of the body of the mandible in a 60-year-old male patient. The pathogenesis, clinical, radiological features and differential diagnosis have been discussed. PMID:24701547

Atlantoaxial Joint Synovial Cyst: Diagnosis and Percutaneous Treatment  

SciTech Connect

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.

The diagnosis and management of synovial cysts: Efficacy of surgery versus cyst aspiration  

PubMed Central

Background: The surgical management of lumbar synovial cysts that have extruded into the spinal canal remains controversial (e.g. decompression with/without fusion). Methods: The neurological presentation, anatomy, pathophysiology, and surgical challenges posed by synovial cysts in the lumbar spine are well known. Neurological complaints typically include unilateral or, more rarely, bilateral radicular complaints, and/or cauda equina syndromes. Anatomically, synovial cysts constitute cystic dilatations of synovial sheaths that directly extrude from facet joints into the spinal canal. Pathophysiologically, these cysts reflect disruption of the facet joints often with accompanying instability, and potentially compromise both the cephalad and caudad nerve roots. Results: Aspiration of lumbar synovial cysts, which are typically gelatinous and non-aspirable, and typically performed by “pain specialists” (e.g. pain management, rehabilitation, radiologists, others) utilizing fluoroscopy or CT-guided aspiration, is associated with 50–100% failure rates. Surgical decompression with/without fusion (as the issue regarding fusion remains unsettled) results in the resolution of back and radicular pain in 91.6–92.5% and 91.1–91.9% of cases, respectively. Conclusions: After a thorough review of the literature, it appears that the treatment with the best outcome for patients with synovial cysts is cyst removal utilizing surgical decompression; the need for attendant fusion remains unsettled. The use of an alternative treatment, percutaneous aspiration of cysts, appears to have a much higher recurrence and failure rate, but may be followed by surgery if warranted. PMID:22905322

Cyst-like lesions of the knee joint and their relation to incident knee pain and development of radiographic osteoarthritis: The MOST study  

PubMed Central

Objective To determine whether intra- and periarticular cyst-like lesions of the knee are associated with incident knee pain and incident radiographic knee osteoarthritis (OA). Design The Multicenter Osteoarthritis (MOST) Study is a cohort of individuals who have or are at high risk for knee OA. Using a nested case-control study design, we investigated the associations of cyst-like lesions (Baker’s, meniscal and proximal tibiofibular joint (PTFJ) cysts, and prepatellar and anserine bursitides) with (a) incident pain at 15- or 30-month follow-up and (b) incident radiographic OA at 30-month follow-up. Baseline cyst-like lesions were scored semiquantitatively using the Whole Organ Magnetic Resonance Imaging Score (WORMS). Conditional logistic regression models were used to assess the relation between these lesions and the outcomes, adjusting for potential confounding factors (i.e. cartilage loss, meniscal damage, bone marrow lesions, synovitis and joint effusion, which were also scored using WORMS). Results Incident knee pain study included 157 cases and 336 controls. Prevalence of meniscal and PTFJ cysts in the case group was twice that in the control group (9 (6%) vs. 9 (3%) and 9 (6%) vs. 10 (3%), respectively). Incident radiographic OA study included 149 cases and 298 controls. Prevalence of grade 2 Baker’s cysts and PTFJ cysts in the case group was approximately 4 times that in the control group (16 [11%] vs. 9 [3%] and 6 [4%] vs. 3 [1%], respectively). However, none of the cyst-like lesions was associated with incident pain or radiographic OA after fully adjusted logistic regression analyses and correction of p-values for multiple comparisons. Conclusion None of the analyzed lesions was an independent predictor of incident knee pain or radiographic OA. Intra- and periarticular cyst-like lesions are likely to be a secondary phenomenon seen in painful or OA-affected knees, rather than a primary trigger for incident knee pain or radiographic OA.

Papillary carcinoma on a thyroglossal duct cyst: diagnostic problems and therapeutic dilemma. A case report.  

PubMed

Thyroglossal duct cysts are one of the most common congenital abnormalities of the cervical region. Complications of these swellings are rare, and among these, appearance of a carcinoma has also been noted. We present a case of papillary carcinoma arising in a thyroglossal duct cyst in 20-year-old woman with a swelling of about 4 cm, located at the middle region of the neck over the hyoid bone. Our patient was treated using a modified Sistrunk operation, in which thyroidectomy proved crucial for the correct diagnosis and continuation of appropriate treatment. Our case confirms the difficulty in distinguishing a primitive thyroglossal duct carcinoma from a synchronous metastatic papillary carcinoma of the thyroid. This dilemma often remains unresolved.

Synovial cysts of the proximal tibiofibular joint: three case reports.  

PubMed

Synovial cysts are fluid-filled masses lined with synovium and located within or about joints. The main symptoms are pain and/or neurological deficits. They can be intraneural or extraneural or develop between or within muscles. Synovial cysts that arise at a distance from a joint raise diagnostic challenges. We report three cases of synovial cysts of the proximal tibiofibular joint, including an intramuscular cyst responsible for paralysis of the anterolateral leg muscles. Tibiofibular synovial cysts are less common than popliteal cysts, and their pathophysiology is poorly understood. Pressure on the common peroneal nerve is the main complication and requires careful surgical excision of the cyst. Injection of a glucocorticoid into the cyst can be used as the first-line treatment in patients without common peroneal nerve symptoms. PMID:12102284

Synovial Cyst Mimicking an Intraspinal Sacral Mass  

PubMed Central

A 68-year-old female had a three-week history of severe low back pain radiating down the posterior left buttocks and left leg exacerbated by standing and walking. Lumbar spine MRI revealed cystic mass with similar intensity to cerebrospinal fluid located on dorsolateral left side of the sacral spinal canal inferior to the S1 pedicle. There was compression of left exiting S1 and traversing S2 nerve roots. Neurosurgery consult was requested to evaluate the cystic mass in the sacral spinal canal. After clinical evaluation, an unusually located synovial cyst was thought possible. Cyst contents were heterogeneous, suggestive of small hemorrhage and acute clinical history seemed reasonable. Left S1 and partial left S2 hemilaminectomy was performed and an epidural, partially hemorrhagic cyst was removed. There was no obvious connection to the ipsilateral L5-S1 facet joint. Pathology revealed synovial cyst, and the patient's leg pain was improved postoperatively. This synovial cyst was unusual as it had no connection with the facet joint intraoperatively and its location in the sacral canal was uncommon. PMID:24716025

Detection of Giardia cysts by using the polymerase chain reaction and distinguishing live from dead cysts.  

PubMed Central

A method was developed for the detection of Giardia cysts by using the polymerase chain reaction (PCR) and the giardin gene as the target. DNA amplification by PCR, using giardin DNA as the target, resulted in detection of both live and dead cysts. When giardin mRNA was used as the target, the ability to amplify cDNA by PCR depended on the mode of killing. Cysts killed by freezing were not detected by PCR when giardin mRNA was the target. Cysts killed by heating or exposure to monochloramine, however, gave positive detection signals for both DNA and giardin mRNA targets. The amount of giardin mRNA and total RNA was significantly increased in live cysts following the induction of excystation. Cysts killed by freezing, heating, or exposure to monochloramine did not show a change in RNA content. The detection of the giardin gene by PCR permits a sensitive and specific diagnosis for Giardia spp. Discrimination between live and dead cysts can be made by measuring the amounts of RNA or PCR-amplified product from the giardin mRNA target before and after the induction of excystation.

Liver Hydatid Cyst with Transdiaphragmatic Rupture and Lung Hydatid Cyst Ruptured into Bronchi and Pleural Space  

SciTech Connect

The aim of this case study is to present effectiveness of percutaneous drainage as a treatment option of ruptured lung and liver hydatid cysts. A 65-year-old male patient was admitted with complicated liver and lung hydatid cysts. A liver hydatid cyst had ruptured transdiaphragmatically, and a lung hydatid cyst had ruptured both into bronchi and pleural space. The patient could not undergo surgery because of decreased respiratory function. Both cysts were drained percutaneously using oral albendazole. Povidone-iodine was used to treat the liver cyst after closure of the diaphragmatic rupture. The drainage was considered successful, and the patient had no recurrence of signs and symptoms. Clinical, laboratory, and radiologic recovery was observed during 2.5 months of catheterization. The patient was asymptomatic after catheter drainage. No recurrence was detected during 86 months of follow-up. For inoperable patients with ruptured liver and lung hydatid cysts, percutaneous drainage with oral albendazole is an alternative treatment option to surgery. The percutaneous approach can be life-saving in such cases.

Transsphenoidal cyst cisternostomy with a keyhole dural opening for sellar arachnoid cysts: technical note.  

PubMed

A less invasive transsphenoidal approach with a keyhole dural opening for intrasellar arachnoid cysts is described. This approach was used to address seven sellar cystic lesions with suprasellar extension; they were six intrasellar arachnoid cysts (IACs) and one Rathke's cleft cyst (RCC). In all cases, preoperative MRI revealed cerebrospinal fluid (CSF) intensity on both T1- and T2-weighted images. On preoperative contrast-enhanced MRI, five of the six IACs manifested posterior displacement of the flattened pituitary gland toward the dorsum sellae; one of the six IACs and the RCC exhibited a flattened pituitary gland on the anterior surface of the cyst. Wide cyst cisternostomy through a keyhole dural opening was carried out safely using a microscope with the support of a thin angled endoscope (30° and/or 70°, diameter 2.7 mm). As we aimed to avoid iatrogenic injury of the pituitary function, we found it difficult to obtain a sufficiently wide and precise opening of the cyst wall when the pituitary gland was located on the anterior surface of the cyst wall. Our approach facilitates safe cyst cisternostomy as wide as that obtainable by transcranial manipulation. In addition, CSF leakage is prevented by dural plasty using the fascia lata and stitching with 6-0 monofilament sutures. This technique can be adapted to address various sellar cystic lesions. However, as the posterior or anterior displacement of the normal pituitary gland in the presence of IACs or RCCs, respectively, affects the width of the cyst opening, our technique is more suitable for IACs than RCCs.

We present a 29-year-old woman who was admitted to the emergency department with shortness of breath. Using echocardiography, a giant multi-cystic mass was detected in the right ventricle, attached to the septal leaflet of the tricuspid valve and basal portion of the interventricular septum. Serologic tests (hydatid cyst antibody) confirmed Echinococcus infection. Lung computed tomography with intravenous contrast showed involvement of the pulmonary vasculature. The patient underwent cardiac surgery and the large cardiac cyst and the one in the right pulmonary artery branch were both removed. The tricuspid valve was also replaced by a bioprosthetic one. Albendazole was started preoperatively and was continued for six months after surgery. The patient recovered uneventfully and was followed up for one year. This is a report of a rare case of a very large cardiac hydatid cyst complicated by pulmonary embolism with attachments to both the tricuspid valve and interventricular septum. PMID:24862620

The Tale of Spring Water Cysts

Congenital pericardial diverticula and cysts are extremely uncommon lesions within the anterior mediastinum. Both lesions derive from the pericardial celom and represent different stages of a common embryogenesis. Initial reports date from the 19th century. Surgical pioneers were Otto Pickhardt, who removed a pericardial cyst at Lenox Hill Hospital in New York in 1931, and Richard Sweet, who accomplished the first resection of a pericardial diverticulum at Massachusetts General Hospital in Boston in 1943. These lesions were also called spring water cysts because they usually contain watery, crystal-clear fluid. This history outlines the milestones of evolving surgical management, from the first report in 1837 up to the present time. PMID:22719140

Dermoid cysts are the most common germ cell tumors of the ovary in women of reproductive age. We report 67 cases of patients with dermoid cysts (mean age, 31.31 years) originating from the ovary treated from 1994 to 2006 at the Obstetrics and Gynecology Department of Aschaffenburg Hospital-Clinic in Germany. Most patients (60) underwent cyst removal. In two patients salpingo-oophorectomy was performed and in five partial oophorectomy was performed. Additional surgery ensuing laparotomy was never necessary. None of the patients had long-term postoperative complications. Two patients were at nine and 15 weeks of gestation and postoperatively were well following termination of pregnancy. In a group of 43 women, who desired pregnancy, 37 pregnancies resulted. The overall intrauterine pregnancy rate was 83.7%; one patient had an ectopic pregnancy (2.32%). To receive more information on this disease, treatment should be performed according to international protocols. PMID:18581767

ON HÆMORRHAGIC CYSTS OF THE THYROID GLAND  

PubMed Central

1. All the features peculiar to the gross cysts of the thyroid gland which possess fluid contents appear to indicate that they are essentially of hæmorrhagic origin. 2. While these gross cysts would seem more especially to occur in glands which already present the features of parenchymatous goitre, the theory of Wölfler that they originate as a consequence of spontaneous rupture of the vesicles is unsatisfactory. 3. It would seem more probable that these large cysts are due to rupture, traumatic or otherwise, of some of the vessels of the organ. The frequent signs of small hæmorrhages in cases of parenchymatous goitre without evidence of associated gross change in the surrounding vesicles, the structure of the organ and its exposed position, all appear to favour this view.

Bacterially induced bone destruction: mechanisms and misconceptions.  

PubMed Central

Normal bone remodelling requires the coordinated regulation of the genesis and activity of osteoblast and osteoclast lineages. Any interference with these integrated cellular systems can result in dysregulation of remodelling with the consequent loss of bone matrix. Bacteria are important causes of bone pathology in common conditions such as periodontitis, dental cysts, bacterial arthritis, and osteomyelitis. It is now established that many of the bacteria implicated in bone diseases contain or produce molecules with potent effects on bone cells. Some of these molecules, such as components of the gram-positive cell walls (lipoteichoic acids), are weak stimulators of bone resorption in vitro, while others (PMT, cpn60) are as active as the most active mammalian osteolytic factors such as cytokines like IL-1 and TNF. The complexity of the integration of bone cell lineage development means that there are still question marks over the mechanism of action of many well-known bone-modulatory molecules such as parathyroid hormone. The key questions which must be asked of the now-recognized bacterial bone-modulatory molecules are as follows: (i) what cell population do they bind to, (ii) what is the nature of the receptor and postreceptor events, and (iii) is their action direct or dependent on the induction of secondary extracellular bone-modulating factors such as cytokines, eicosanoids, etc. In the case of LPS, this ubiquitous gram-negative polymer probably binds to osteoblasts or other cells in bone through the CD14 receptor and stimulates them to release cytokines and eicosanoids which then induce the recruitment and activation of osteoclasts. This explains the inhibitor effects of nonsteroidal and anticytokine agents on LPS-induced bone resorption. However, other bacterial factors such as the potent toxin PMT may act by blocking the normal maturation pathway of the osteoblast lineage, thus inducing dysregulation in the tightly regulated process of resorption and replacement of bone matrix. At the present time, it is not possible to define a general mechanism by which bacteria promote loss of bone matrix. Many bacteria are capable of stimulating bone matrix loss, and the information available would suggest that each organism possesses different factors which interact with bone in different ways. With the rapid increase in antibiotic resistance, particularly with Staphylococcus aureus and M. tuberculosis, organisms responsible for much bone pathology in developed countries only two generations ago, we would urge that much greater attention should be focused on the problem of bacterially induced bone remodelling in order to define pathogenetic mechanisms which could be therapeutic targets for the development of new treatment modalities.

Objectives The aim of this study was to evaluate the principal features of “glandular odontogenic cyst” (GOC), by systematic review (SR), and to compare their frequencies among four global groups. Methods The databases searched were the PubMed interface of MEDLINE and LILACS. Only those reports of GOCs that occurred in a series in the reporting authors' caseload were considered. All cases were confirmed histopathologically. Results 18 reports on 17 series of consecutive cases were included in the SR. GOC affected males twice as frequently and the mandible almost three times as frequently. The mean age at first presentation was 44 years, coincident with that of the Western global group, in which the largest proportion of reports and cases first presented in the second half of the fifth decade. However, age at presentation of GOCs in the East Asian and sub-Saharan African global groups was nearly a decade younger, this was significant. Six reports included details of at least one clinical presentation. Eight reports included at least one conventional radiological feature. There were some significant differences between global groups. The Western global group had a particular predilection for the anterior sextants of both jaws. The sub-Saharan African group displayed buccolingual expansion (as did the Latin American group) and tooth displacement in every case. 18% of GOCs recurred overall, except in the sub-Saharan African global group. Conclusions GOCs have a marked propensity to recur in most global groups. GOCs presented in older patients and with swellings, affected the anterior sextants of both jaws, and radiologically were more likely to present as a well-defined unilocular radiolucency with buccolingual expansion. Tooth displacement, root resorption and an association with unerupted teeth occurred in 50%, 30% and 11% of cases, respectively. PMID:20203274

The Within-Subregion Relationship between Bone Marrow Lesions and Subsequent Cartilage Loss in Knee Osteoarthritis  

PubMed Central

Bone marrow lesions are believed to increase risk of knee osteoarthritis (OA) progression. Whether their effect is local and whether it can be explained by other types of bone lesions concomitantly present in the same subregion is unclear. We evaluated bone lesion frequency in subregions without cartilage lesions and cartilage lesion frequency in subregions without bone lesions and investigated the within-subregion bone marrow lesion/subsequent cartilage loss relationship after adjusting for other types of bone lesions at baseline. Individuals with knee OA had MRI at baseline and two years later. Bone marrow lesions, bone cysts, bone attrition, and cartilage integrity were scored within tibiofemoral subregions. Logistic regression with GEE to account for correlation among multiple subregions within a knee was used to estimate ORs for cartilage loss associated with bone marrow lesions adjusting for age, gender, BMI, and bone attrition and cysts in the same subregion. Analyzing 1953 subregions among 177 knees, 90% of subregions had no bone lesion at baseline. Only 0–3% of subregions without cartilage lesions had bone lesions in the same subregion; in contrast, 5–33% of subregions without bone lesions had cartilage lesions. Bone marrow lesions at baseline were associated with 2 year cartilage loss in the same subregion, adjusting for other types of bone lesions at baseline (adjusted OR 3.74, 95% CI 1.59, 8.82). In persons with knee OA, bone marrow lesions were rare at early disease stages but predicted subregional cartilage loss after accounting for the presence of other types of bone lesions in the same subregion.

Pancaost syndrome related to hydatid cyst  

PubMed Central

Pancoast syndrome remains a rare presentation of pulmonary diseases. Even in endemic area of echinococcosis, lung's hydatid cyst is seldomly revealed by this syndrome. We report a case of a 38 year old male patient who presented to our department with neck and left superior limb pain associated with palmar muscle atrophy and Horner's syndrome. Radiological investigations suggested the diagnosis of hydatid cyst of the left lung apex which was confirmed by surgical excision and pathological examination of the lesion. This case highlights an uncommon etiology of Pancoast syndrome which might mislead physicians in their practice. PMID:23717731

[Renal hydatid cyst: radiologic features and therapy].  

PubMed

Hydatid disease is endemic in some Mediterranean countries. Kidney is a relatively rare site, representing 2 to 3 % of all visceral sites. The diagnosis of hydatid cyst of the kidney is suspected in epidemiological, clinical, radiological and biological arguments. It remains clinically silent for a long time and only presents at the stage of complications. Ultrasound can suspect the hydatid nature of the lesion in 50 % of cases. Computed tomography and magnetic resonance imaging are helpful in the event of problem of differential diagnosis. The standard treatment for renal hydatid cyst is resection of the prominent dome and nephrectomy is indicated in cases of destroyed kidney. PMID:23178095

Traumatic mesenteric cyst after blunt abdominal trauma  

PubMed Central

Mesenteric cysts are rare abdominal tumors of unclear histologic origin, usually asymptomatic. Post-traumatic mesenteric cyst usually results as a consequence of a mesenteric lymphangitic rupture or a hematoma followed by absorption and cystic degeneration. The preoperative histological and radiological diagnosis is difficult. We present the case of a 45-year-old male patient with sizable, palpable abdominal tumor, the gradual swelling of which the patient himself combined with the blunt abdominal trauma he acquired from an opponent's knee in a football game 5 months ago.

Primary Hydatid Cyst of the Thyroid Gland  

PubMed Central

Primary hydatid cyst of thyroid gland is an exceptional localization even in Morocco where echinococcal disease is endemic. A 23-year-old woman presented with multiples cystic lesions of the thyroid revealed by neck mass and dyspnea. She underwent a subtotal thyroidectomy. The diagnosis of hydatid cyst was made preoperatively and was confirmed by histological studies. Further investigation failed to identify any other evidence of systemic hydatidosis. The patient has remained asymptomatic for 24 months after surgery. The possibility of hydatid disease, though rare, should be always kept in mind, for patients with cystic lesions of the thyroid, because a needle aspiration biopsy is a potentially harmful procedure.

The Toxoplasma gondii Cyst Wall Protein CST1 Is Critical for Cyst Wall Integrity and Promotes Bradyzoite Persistence  

PubMed Central

Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst wall recognize carbohydrates, identification of the components of the cyst wall has been technically challenging. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large mucin-like domain. CST1 is responsible for the Dolichos biflorus Agglutinin (DBA) lectin binding characteristic of T. gondii cysts. Deletion of CST1 results in reduced cyst number and a fragile brain cyst phenotype characterized by a thinning and disruption of the underlying region of the cyst wall. These defects are reversed by complementation of CST1. Additional complementation experiments demonstrate that the CST1-mucin domain is necessary for the formation of a normal cyst wall structure, the ability of the cyst to resist mechanical stress, and binding of DBA to the cyst wall. RNA-seq transcriptome analysis demonstrated dysregulation of bradyzoite genes within the various cst1 mutants. These results indicate that CST1 functions as a key structural component that confers essential sturdiness to the T. gondii tissue cyst critical for persistence of bradyzoite forms. PMID:24385904

Popliteal cysts and subgastrocnemius bursitis are associated with knee symptoms and structural abnormalities in older adults: a cross-sectional study  

PubMed Central

Introduction The role of popliteal cysts and subgastrocnemius bursitis in knee joint homeostasis is uncertain. The aim of this study is to describe cross-sectional associations between popliteal cysts, subgastrocnemius bursitis, knee symptoms and structural abnormalities in older adults. Methods A cross-sectional sample of 900 randomly-selected subjects (mean age 63 years, 48% female) were studied. Knee pain, stiffness and dysfunction were assessed by self-administered Western Ontario McMaster Osteoarthritis Index (WOMAC) questionnaire. Radiographic knee osteophyte and joint space narrowing (JSN) were recorded. Magnetic resonance imaging (MRI) was utilized to assess popliteal cysts, subgastrocnemius bursitis, cartilage defects and bone marrow lesions (BMLs). Results Popliteal cysts were present in 11.7% and subgastrocnemius bursitis in 12.7% of subjects. Subgastrocnemius bursitis was more common in those with popliteal cyst (36.2% versus 9.7%, P <0.01). In multivariable analyses, popliteal cysts were significantly associated with increased osteophytes in both medial and lateral tibiofemoral compartments while subgastrocnemius bursitis was associated with increased osteophytes and JSN in the medial tibiofemoral compartment. Both were significantly associated with cartilage defects in all compartments, and with BMLs in the medial tibiofemoral compartment. Furthermore, both popliteal cysts and subgastrocnemius bursitis were significantly associated with increased weight-bearing knee pain but these associations became non-significant after adjustment for cartilage defects and BMLs. Conclusions Popliteal cysts and subgastrocnemius bursitis are associated with increased symptoms as well as radiographic and MRI-detected joint structural abnormalities. Longitudinal data will help resolve if they are a consequence or a cause of knee joint abnormalities. PMID:24581327

Atypical Intracranial Epidermoid Cysts: Rare Anomalies with Unique Radiological Features  

PubMed Central

Epidermoid cysts are benign slow growing extra-axial tumours that insinuate between brain structures, while their occurrences in intra-axial or intradiploic locations are exceptionally rare. We present the clinical, imaging, and pathological findings in two patients with atypical epidermoid cysts. CT and MRI findings for the first case revealed an intraparenchymal epidermoid cyst that demonstrated no restricted diffusion. The second case demonstrated an aggressive epidermoid cyst that invaded into the intradiploic spaces, transverse sinus, and the calvarium. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

Gastric duplication cysts are rare variety of gastrointestinal duplications. Sometimes they may present with complications like hemorrhage, infection, perforation, volvulus, intussusception and rarely neoplastic changes in the gastric duplication cyst. We present one and half year old male child who developed sudden abdominal distension with pain and fever for two days. Ultrasound revealed a cystic mass in the hypochondrium and epigastric regions. On exploration an infected and perforated gastric duplication cyst was found. Surgical excision of most part of cyst wall with mucosal stripping of the rest was performed. Histopathology confirmed the diagnosis of gastric duplication cyst. Early surgical intervention can result in good outcome. PMID:22953249

Baker's Cyst Filled with Hematoma at the Lower Calf  

PubMed Central

Baker's cyst is a distension of the gastrocnemius-semimembranosus bursa of the knee, which communicates with the posterior portion of the joint capsule. Baker's cyst is commonly located in the inferomedial or superficial layers of the knee joint and rarely extends laterally or proximally. Complications of Baker's cysts are dissection, rupture, pseudothrombophlebitis, leg ischemia, nerve entrapment, and compartment syndrome. However, hematomas in the Baker's cyst have not been reported in Korea. We report a rare case of hematoma in the Baker's cyst with subfascial extension into the calf. The hematoma was demonstrated by magnetic resonance imaging and removed by mass excision. PMID:25505709

Generation of meniscal cyst after arthroscopic meniscal repair.  

PubMed

Meniscal cyst is a common condition and it has been suggested that the degeneration of the meniscus may be largely associated with the occurrence of a meniscal cyst. However, meniscal cysts forming after meniscal repair are exceedingly rare. Previous reports have suggested that meniscal cyst after meniscal repair can be attributed to the cystic degeneration of the meniscus and the thread used for the meniscal suture. In this report, the developmental mechanism of a meniscal cyst after meniscal repair suturing is discussed. PMID:15483551

Keratin metaplasia in the epithelial lining of odontogenic cysts  

PubMed Central

Objective: To find the prevalence of keratin metaplasia and its relation with clinico-pathological profile of the odontogenic cyst. Materials and Methods: Odontogenic cysts were studied histologically with special stains to identify the presence of keratin and compared with various parameters such as underlying connective tissue inflammation, average epithelial thickness, and site of the cyst, type of the cyst, age and the sex of the patient. Results: Of 71 cases of various odontogenic cysts, 26 (36.6%) cases exhibited keratinization in the epithelial lining. In cysts with severe inflammation there is absence of keratinization. Conclusions: This study reveals higher prevalence of keratin metaplasia in the odontogenic cysts. Furthermore, inflammation is found to be one of factor influencing keratin metaplasia. PMID:25210349

Management of cervical thoracic duct cyst with cyst-venous anastomosis  

PubMed Central

INTRODUCTION Cervical thoracic duct cyst (CTDC) is a rare cause of lateral neck mass. Surgical excision with ligation of the cervical thoracic duct is the current standard for definitive management with symptomatic patients. We report the first case of an alternative method of management performing a cyst venous anastomosis for decompression. PRESENTATION OF CASE A 77 year old female presented with a six month history of left arm pain, swelling and a left-sided cystic neck mass. She was treated with cyst-venous anastomosis between the cyst wall and the left internal jugular vein. At two year follow-up, she has had resolution of pain and no recurrence of the mass. DISCUSSION Many potential etiologies have been proposed for CTDC, though surgical management of this rare problem has consistently required cyst excision and thoracic duct ligation. Few innovative modes of therapy have been developed to address this problem in a less invasive manor. Maintaining a more natural thoracic duct anatomy decreases the likely of complications associated with duct ligation. CONCLUSION Cyst-venous anastomosis for the management of CTDC provides an effective, novel form of treatment which maintains the integrity of the thoracic duct and avoids potential complications associated with duct ligation.

Choledochal cysts: our ten year experience.  

PubMed

We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates. PMID:22708223

Cyclic GMP controls R. centenum cyst development  

PubMed Central

Adenylyl cyclases are widely distributed across all kingdoms whereas guanylyl cyclases are generally thought to be restricted to eukaryotes. Here we report that the ?–proteobacterium Rhodospirillum centenum secretes cGMP when developing cysts and that a guanylyl cyclase deletion strain fails to synthesize cGMP and is defective in cyst formation. The R. centenum cyclase was purified and shown to effectively synthesize cGMP from GTP in vitro, demonstrating that it is a functional guanylyl cyclase. A homolog of the Escherichia coli cAMP receptor protein (CRP) is linked to the guanylyl cyclase and when deleted is deficient in cyst development. Isothermal calorimetry (ITC) and differential scanning fluorimetry (DSF) analyses demonstrate that the recombinant CRP homolog preferentially binds to, and is stabilized by cGMP, but not cAMP. This study thus provides evidence that cGMP has a crucial role in regulating prokaryotic development. The involvement of cGMP in regulating bacterial development has broader implications as several plant-interacting bacteria contain a similar cyclase coupled by the observation that Azospirillum brasilense also synthesizes cGMP when inducing cysts.

[Sacral perineural cyst--report of a case].  

PubMed

The presence of cysts within the sacral spinal canal, so-called sacral cysts, is described in literature. These include 'sacral perineural cyst', 'sacral extradural cyst', 'occult intrasacral meningocele' and 'anterior sacral meningocele'. Sacral perineural cyst in these cystic disorders was first described as an incidental autopsy finding by Tarlov in 1938. Since then, several reports have been made describing the sign and symptom, neurological findings, roentgenographic diagnosis and cause and origin of the sacral perineural cysts, although many problems are not yet solved satisfactorily. This cyst occurs on the extradural components of sacral or coccygeal nerve roots. Although most are asymptomatic, these occasionally cause low back pain, sciatic and sacrococcygeal pain, sensory and motor disturbance in the lower extremities, and urinary dysfunction, which symptoms are similar to those brought on by lumbar disc herniation. In 1948, Tarlov reported a case of sciatic pain due to a perineural cyst, the removal of which relieved the symptoms. Symptoms occur because adjacent nerve roots are impinged upon by the thin-walled, fluid-filled cysts, which are formed in a space between the endoneurium and the perineurium. Microscopically, the cyst walls consist of peripheral nerve fibers or ganglionic cells covered with meningeal epithelium. Communication of the cyst with subarachnoid cerebrospinal fluid may be poor, but myelogram and CT myelogram demonstrate the cysts filling with contrast media. With the advent of magnetic resonance imaging (MRI), imaging of the sacral perineural cysts has improved. Recently we had the opportunity to evaluate a patient in whom perineural cysts had caused considerable erosion of the sacrum.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3221973

Introduction: Male pelvic floor cysts are a rare clinical entity that include: Wolffian duct remnants, Müllerian duct remnants, cysts of the seminal vesicles, prostate and ejaculatory duct/vas deferens cysts.?Case report: We report the clinical case of a 21-year-old male patient with a history of previous surgery in childhood and more precisely: partial colectomy for congenital megacolon, removal of dysplastic right kidney and subsequent surgical adhesiolysis for bowel obstruction.?At 17, the patient was submitted to MRI for groin pain with an incidental finding of a cystic mass at the level of the right seminal vesicle. Consequently, a TUR-ED was performed at another urology unit, for a suspected seminal vesicle ectasia, without resolution of pain symptoms. The patient was referred to us for persistent genitourinary infections, ejaculation disorder and episodes of gross hematuria. An additional MRI confirmed the presence of a cystic mass of 5,5 cm with a suspected opening into prostatic urethra. Urethrocystoscopy and urethrocystography retrograde confirmed this anatomical communication. For the persistence of the symptoms we performed retropubic surgical exeresis of the mass, with a histopathological finding of benign cyst of the vas deferens.?Two major postoperative complications were reported: a pelvic hematoma that required surgical exploration and a urinary extravasation at the level of prostatic urethra, which resolved with prolonged urethral catheterization.?Conclusions: Male pelvic floor cysts are a rare disease with a complex clinical and therapeutic management. A correct diagnosis is based on clinical signs and symptoms together with imaging studies of the pelvic region. The high risk of erectile dysfunction and ejaculatory disorders correlated to a surgical approach, recommend a treatment of these lesions only for symptomatic cases. PMID:24665031

Gross pathology and endocrinology of ovarian cysts in bitches.  

PubMed

A total of 73 bitches with ovarian cysts were ovariohysterectomized. Cysts were characterized by gross pathology and endocrine parameters. Therefore, oestradiol-17ß and progesterone concentrations were assessed in cyst-fluid and corresponding blood plasma in each bitch. Our data demonstrated that multiple cysts were often present in a single individual (82%) and that cysts were commonly found on both ovaries (77%). The number of cysts per individual varied from 1 to 35. Most cysts were small in size (range 0.2-4.0 cm in diameter). No cyst was found to produce solely oestradiol-17ß or progesterone. Plasma levels of oestradiol-17ß and progesterone for a given individual were positively correlated with levels of these same hormones in their cyst-fluid (r = 0.334 and p = 0.001 for oestradiol-17ß; r = 0.419 and p < 0.001 for progesterone). Our study is the first to provide a comprehensive evaluation of the gross pathology and endocrinology of ovarian cysts in a larger number of bitches. PMID:24698026

CD56 Expression in Odontogenic Cysts and Tumors  

PubMed Central

Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopathological similarities. Materials and methods. In this cross-sectional, analytical study the subjects were 22 ameloblastomas, 13 dentigerous cysts, 10 keratocystic odontogenic tumors (KCOT), 4 adenomatoid odontogenic tumors (AOT), 3 orthokeratinized odonto-genic cysts, 3 calcifying odontogenic cysts (COC) and one glandular odontogenic cyst (GOC). All the samples were examined for CD56 immunoreactivity. Data were analyzed using chi-square test. Results. Twenty cases (91%) of ameloblastomas, 3 (75%) AOT, 4 (40%) KCOT and one case of GOC were positive for CD56. None of the dentigerous cysts, COC and orthokeratinized odontogenic cysts was CD56-positive. There was a significant difference in the CD56 expression between ameloblastoma and dentigerous cyst, as well as COC. Also, KCOT showed significantly higher expression than orthokeratinized odontogenic cyst. Conclusion. In this study CD56 expression was limited to the odontogenic tumors and more aggressive cystic lesions. This marker can be a useful aid for distinguishing cysts and tumors from similar lesions.

Species of Heterodera cysts in cereal fields in Flanders.  

PubMed

Heterodera is a genus of cyst-forming nematodes, including the cereal cysts which can provoke yield reductions in grain crops. As little is known about the occurrence of these cysts in Belgian grain fields, a survey was organized, starting in Flanders. Soil samples were taken from 50 fields where cereals are grown in rotation with mainly beet, potato and vegetables. Cysts were extracted from the 112 samples and 10 individuals per sample were identified up to species level by morphometrical and morphological observations. The beet cyst nematode, Heterodera schachtii, was found in 34 fields (56%) at infestation levels varying from 0.6 to 1322 cysts/kg soil. Other Heterodera species (e.g. H. trifolii, H. mani) were found in low numbers and sometimes in mixtures with H. schachtii, but no cereal cysts were detected. This survey confirms that beet cyst nematodes are a problem in Flanders. The few cereal cysts that might be present were perhaps not detected due to the few individuals that were identified. For this reason, molecular identification tools which allow fast and accurate identification of Heterodera species would be very useful.

Arthroscopic treatment of symptomatic paralabral cysts in the hip.  

PubMed

Acetabular labral tears or paralabral cysts in the hip are frequently detected using magnetic resonance imaging or arthrography. Unlike parameniscal cysts in the knee and paralabral cysts in the shoulder, reports of the outcomes of surgical treatment for paralabral cysts in the hip recalcitrant to conservative management are limited in the literature.The authors report 2 cases of paralabral cysts in the hip that were treated with arthroscopic surgery. The patients presented with chronic hip pain, and preoperative magnetic resonance imaging showed paralabral cysts at the superior aspect of the acetabulum. After failure of conservative management for more than 6 months, arthroscopic surgery was performed while the patients were under general anesthesia and in a supine position on a fracture table. Arthroscopic examination confirmed the preoperative diagnosis of paralabral cysts with degenerative labral fibrillation or tears in both patients. Arthroscopic cyst decompression and debridement of the degenerative labral tissues were performed using an arthroscopic thermal probe and a shaver.Clinical outcomes, determined by the Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index score, and University of California, Los Angeles activity score, were satisfactory for the 2 patients at 2 and 3 years postoperatively, respectively. Magnetic resonance imaging obtained for 1 patient at 6 months postoperatively showed complete decompression of the paralabral cyst. The authors believe that arthroscopic treatment for symptomatic hip paralabral cysts is a safe and effective procedure with excellent clinical outcomes. PMID:23464960

The Toxoplasma gondii cyst wall protein CST1 is critical for cyst wall integrity and promotes bradyzoite persistence  

SciTech Connect

Toxoplasma gondii infects up to one third of the world’s population. A key to the success of T.gondii is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large mucin-like domain. CST1 is responsible for the Dolichos biflorus Agglutinin (DBA) lectin binding characteristic of T. gondii cysts. Deletion of CST1 results in a fragile brain cyst phenotype revealed by a thinning and disruption of the underlying region of the cyst wall. These defects are reversed by complementation of CST1. Additional complementation experiments demonstrate that the CST1-mucin domain is necessary for the formation of a normal cyst wall structure, the ability of the cyst to resist mechanical stress and binding of DBA to the cyst wall. RNA-seq transcriptome analysis demonstrated dysregulation of bradyzoite genes within the various cst1 mutants. These results indicate that CST1 functions as a key structural component that reinforces the cyst wall structure and confers essential sturdiness to the T. gondii tissue cyst.

Giant epidermal cyst with intramuscular extension: a rare occurrence.  

PubMed

An epidermal cyst is the most common type of cyst to occur in subcutaneous tissue. When its size is greater than 5?cm, it is recognised as a giant epidermal cyst. A subcutaneous giant epidermal cyst with intramuscular extension is extremely rare. The authors report a case of a 74-year-old man who presented with a painless, slow-growing left gluteal mass of 6-month duration. Examination revealed a large left gluteal mass that was fixed to the underlying structures. A small epidermal cyst with visible punctum was noted at the medial aspect of the mass. MRI demonstrated a large, lobulated left gluteal lesion measuring 20?cm×16?cm×10?cm. The lesion was partly within the gluteal maximus muscle and partly within the subcutaneous tissue. MRI and ultrasound features of the lesion were consistent with a giant epidermal cyst with intramuscular extension. The lesion was excised and histology confirmed the diagnosis. PMID:25661748

Retrorectal Dermoid Cyst: a Rare Clinical Entity  

PubMed Central

The retrorectal space represents the anatomical site at which level we identify the embryologic reminiscents in which it can develop liquid tumors - cysts or solid tumors - neoplasia. These tumors are rare but pose a diagnostic and therapeutic interest. This paper presents the case of a young 18 years-old diagnosed incidentally at a gynecological examination, with a palpable tumor developed, at the retrorectal space. Imaging examinations - transvaginal ultrasound and abdominal - pelvic computer tomographic exam - have supported the presence of a cystic tumor with a maximum diameter of 7.8 cm., in the space retrorectal. The lesion presented surgical indication, so it needed a posterior approach with resection of the coccyx enough for the control and safety of the operation. Histopathological examination revealed a dermoid cyst. Five years after surgery the patient is presented in good general condition, asymptomatic without clinical and imaging signs of local-regional recurrence. PMID:24778859

Glandular odontogenic cyst: A case report  

PubMed Central

Glandular odontogenic cysts (GOCs) are rare intrabony solitary or multiloculated cysts of odontogenic origin. The importance of GOCs lies in the fact that they exhibit a propensity for recurrence similar to keratocystic odontogenic tumors and that they may be confused microscopically with central mucoepidermoid carcinoma. Thus, the oral and maxillofacial radiologists play an important role in definitive diagnosis of GOC based on distinctive cases; though they are rare. In large part, this is due to the GOC's complex and frequently non-specific histopathology. This report describes a case of GOC occurrence in the posterior mandibular ramus region in a 17-year-old female, which is a rare combination of site, age, and gender for occurrence. PMID:24701462

Oesophageal duplication cyst causing neonatal haemoptysis.  

PubMed

Duplication anomalies of the alimentary tract often present with myriad clinical symptoms and signs. There have been no reports of haemoptysis as the presenting feature and oesophageal duplication cyst is not considered as a cause for haemoptysis. An infant presented with this unusual manifestation. Chest X-ray showed persistent right upper zone haziness and contrast enhanced computed tomographic scan showed a multiloculated mass on the right side of the chest. The cystic mass was excised via a right thoracotomy and dense adhesions were noted with the oesophagus. The postoperative period was uneventful and histopathological examination revealed it to be a duplication cyst with ectopic gastric mucosa. Thus, the diagnosis was made retrospectively.

Primary adnexial hydatid cyst mimicking ovarian tumor  

PubMed Central

We report here the rare case of a 28-year-old woman with a large hydatid cyst in her left lower pelvis with an unusual sonographic presentation mimicking a multicystic ovarian tumor. Laparoscopic evaluation revealed normal uterus and ovaries with a swelling in the left retropritoneal area. We decided to reach this tumour by the vaginal route and multiple scolex, daughter cysts were removed via a left lateral vaginal wall incision. The pericystic cavity was thoroughly washed. The patient was discharged on the first postoperative day. Mebendazole (100 mg twice daily) was administered for 4 months. This parasite should be kept in mind and considered when making the differential diagnosis of pelvic cystic masses, particularly if the patient is from an endemic area. PMID:24591878

Splenic Epidermoid Cyst - A Rare Entity  

PubMed Central

C Splenic epidermoid cysts are relatively uncommon. Most often, they are asymptomatic, but they may present with abdominal discomfort, predominantly at young ages. We are reporting a rare case of 12-years-old female child with history of dull intermittent pain, tender palpable mass in left hypochondrium on physical examination. Ultrasonography (USG) of abdomen showed large cyst in upper pole of spleen, and an X ray of chest revealed slightly raised left hemidiaphragm. Axial sections taken on computerized tomography of abdomen showed a large well defined cystic mass near upper pole of spleen, with a thin septum in it. On laparotomy, open total splenectomy was performed. Sections from cystic wall were processed and histopathological examination revealed fibrous tissue covered by stratified squamous epithelium. Although, now-a-days emphasis is being laid on minimal invasive operative procedures which preserve spleen. This case report favours total splenectomy, considering postoperative outcome. The final diagnosis always depends upon histopathological examination. PMID:24701525

Giant epidermoid cyst of the posterior neck.  

PubMed

A 49-year-old man was presented for evaluation of a painless mass on his right posterior neck. The mass had gradually enlarged for a 25-year period without inflammation or rupture. On physical examination, a round, nontender, soft-tissue mass, 8 cm in diameter, was noted on the right posterior neck. The neck is a common site of epidermoid cysts, but a mass more than 5 cm in diameter is rare. A contrast-enhanced neck computed tomographic (CT) scan revealed a 7.6 × 6.5 × 5.7 cm unilocular hypodense mass adjacent to the posterior neck muscles.The mass was completely excised under general anesthesia. A histopathologic examination of the excised specimen resulted in a diagnosis of an epidermoid cyst. The patient was discharged from the hospital on the third postoperative day. There were no recurrences in a 2-year follow-up period. PMID:21586972

Botryoid Odontogenic Cyst: A Diagnostic Chaos  

PubMed Central

Botryoid Odontogenic cyst (BOC) originally described by Weathers and Waldron (1973) is a variant of a lateral periodontal cyst characterized by macroscopic and microscopic multilocular growth pattern. We report a case of BOC in a 21-year-old male patient. Orthopantamogram revealed a multilocular radiolucency extending from 43 to 47. The histological examination of incisional biopsy revealed a thin 2-4 layered non keratinised epithelium without rete ridges resembling a reduced enamel epithelium with few localised plaque like thickenings and occasional mural bulges. These features were suggestive of BOC. The excisional biopsy revealed histological features similar to those of incisional biopsy except for the presence of 5-6 epithelial follicles with outer columnar cells and inner stellate reticulum like cells. CD56 and calretinin immunohistochemical staining (IHC) was done. This paper highlights the unusual appearance of follicles in BOC with differential diagnosis and IHC staining characteristics.

Adenocarcinoma associated with tail gut cyst  

PubMed Central

Primary adenocarcinomas of the presacral (retrorectal) space are rare. The diagnosis is usually delayed because of non-specific symptoms, and is made after a biopsy or surgery. These carcinomas arise from cystic lesions developing from remnants of the embryological postanal gut containing mucous-secreting epithelium, known as tail gut cysts. The potential for infection, perianal fistulas and most importantly, malignant change warrants an early complete surgical resection. From an oncologist’s perspective, the management of these carcinomas has varied, and has included adjuvant chemotherapy and/or radiation therapy. We describe here a rare case of adenocarcinoma associated with a tail gut cyst that was discovered incidentally and resected by a posterior approach (Kraske procedure). The patient has had clinical and periodic radiologic surveillance without any evidence of cancer recurrence for over a year and a half. PMID:23450681

Lumbar Epidural Varix Mimicking Perineural Cyst  

PubMed Central

Lumbar epidural varices are rare and usually mimick lumbar disc herniations. Back pain and radiculopathy are the main symptoms of lumbar epidural varices. Perineural cysts are radiologically different lesions and should not be confused with epidural varix. A 36-year-old male patient presented to us with right leg pain. The magnetic resonance imaging revealed a cystic lesion at S1 level that was compressing the right root, and was interpreted as a perineural cyst. The patient underwent surgery via right L5 and S1 hemilaminectomy, and the lesion was coagulated and removed. The histopathological diagnosis was epidural varix. The patient was clinically improved and the follow-up magnetic resonance imaging showed the absence of the lesion. Lumbar epidural varix should be kept in mind in the differential diagnosis of the cystic lesions which compress the spinal roots. PMID:23741553

Biliary cysts: Etiology, diagnosis and management  

PubMed Central

Biliary cysts (BC) are rare dilatations of different parts of a biliary tract. They account for approximately 1% of all benign biliary diseases. BC occur the most frequently in Asian and female populations. They are an important problem for pediatricians, gastroenterologists, radiologists and surgeons. Clinical presentation and management depend on the BC type. Cholangiocarcinoma is the most serious and dangerous BC complication. The other complications associated with BC involve cholelithiasis and hepatolithiasis, cholangitis, acute and chronic pancreatitis, portal hypertension, liver fibrosis and secondary liver cirrhosis and spontaneous cyst perforation. Different BC classifications have been described in the literature. Todani classification dividing BC into five types is the most useful in clinical practice. The early diagnosis and proper treatment are very important, because BC are associated with a risk of carcinogenesis. A malignancy risk increases with the age. Radiological investigations (ultrasonography, computed tomography, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography) play an important role in BC diagnostics. Currently, prenatal diagnosis using ultrasonography is possible. It allows to differentiate biliary disorders in fetals and to perform the early surgical treatment that improves results. In most patients, total cyst excision with Roux-Y hepaticojejunostomy is the treatment of choice. Surgical treatment of BC is associated with high success rate and low morbidity and mortality. The early treatment is associated with a lower number of complications. Patients following BC surgery require permanent and careful postoperative observation using laboratory and imaging investigations because of possibility of biliary anastomosis stricture and biliary cancer in tissue remnant.

A completely isolated intestinal duplication cyst mimicking ovarian cyst torsion in an adult  

PubMed Central

Intestinal duplications are rare congenital anomalies that can occur anywhere in the gastrointestinal tract. They are most commonly located in the ileum and are usually detected in infancy or early childhood. Duplicated segments are usually firmly attached to and sometimes communicate with the normal gastrointestinal tract. Rarely, intestinal duplications are completely isolated, thus not associated at all with any part of the gastrointestinal tract. Such duplications do not share a common blood supply with the adjacent normal intestinal segment, unlike the usual form of duplication, but rather have a separate vascular pedicle. Reports of completely isolated duplication cysts in adults are extremely rare; we found only five such reports in the English-language medical literature. Here, we report a case of a completely isolated duplication cyst 12 cm long in an adult female. The cyst had no connection to any part of the intestinal tract and had a dedicated vascular pedicle.

Background Renal cysts are common in old patients, and usually remain untreated. Giant renal cyst measuring more than 15 cm in diameter and containing more than 1500 mls of serous fluid are rarely seen. We report a case of a 75-year-old man with a giant right renal cyst. Case presentation A 75-year-old man presented with a five years history of suprapubic pain, abdominal distension. He had no urological symptoms. Physical examination revealed a distended abdomen with shifting dullness. Routine hematology, biochemistry, and serum tumor markers were within normal limits. Erroneously diagnosed as ascites on ultrasonographic examination. Abdominal paracentesis of supposed ascites was performed. The diagnosis of giant renal cyst was finally made by Computed tomography (CT) and patient underwent continuous percutaneous catheter drainage with negative pressure, whereby 8 liters of fluid were removed with negative cytology. Subsequent Computed tomography after 6 months revealed disparition of the cysts, and the patient remained asymptomatic. Conclusion Giant renal cysts are uncommon; we conclude that the CT remains the best exam in patients evaluated for giant renal cyst. This to the best of our knowledge is the largest renal cyst in the medical literature. Studies are needed with particular attention to the factors associated with renal cyst enlargement.

An oral foregut cyst is a rare congenital choristoma lined by the respiratory and/or gastrointestinal epithelium. The exact etiology has not been fully identified, but it is thought to arise from misplaced primitive foregut. This lesion develops asymptomatically but sometimes causes difficulty in swallowing and pronunciation depending on its size. Thus, the first choice of treatment is surgical excision. Surgeons associated with head and neck pathology should include the oral foregut cyst in the differential diagnosis for ranula, dermoid cyst, thyroglossal duct cyst and lymphangioma in cases of pediatric head and neck lesions.

Endoscopic ultrasonography-guided pancreatic cyst ablation (with video).  

PubMed

Pancreatic cystic lesions are being diagnosed with increasing frequency owing to the widespread use of cross-sectional imaging. Although most pancreatic cysts are detected incidentally, they represent a wide spectrum of histopathology, and neoplastic cysts appear to be more prevalent than previously estimated. Some histologic types have malignant potential. Considering the perioperative morbidity associated with surgical resection, deciding whether to operate or observe an indeterminate pancreatic cyst is challenging, and there is a strong clinical need to develop a minimally invasive approach. EUS-guided pancreatic cyst ablation has been investigated in several clinical trials, and may represent a viable alternative to surgical resection. PMID:25376091

Squamoid cyst of pancreatic ducts: a case series describing novel immunohistochemistry, cytology, and quantitative cyst fluid chemistry.  

PubMed

Squamoid cyst of pancreatic ducts (SCPD) is a benign pancreatic cyst often misdiagnosed preoperatively as a mucinous cyst. The histopathologic features are well described but the cytology and quantitative fluid chemistry profiles from fine-needle aspiration have not been reported. This case series discusses the cytology and cyst fluid chemistry profiles in 2 SCPDs and describes morphologic and immunohistochemical features that have not been previously reported. Fine-needle aspiration of 2 SCPDs yielded acellular debris lacking mucin or exfoliated squamous cells. Two cysts had elevated fluid carcinoembryonic antigen (CEA) and amylase levels. Positive immunohistochemical staining included cytokeratin 5/6, pCEA, synaptophysin, and chromogranin (both focal). MUC2 and MUC5AC showed negativity in all cases, while PAX8 showed negative nuclear staining. An accurate preoperative diagnosis of SCPD is potentially difficult in the setting of elevated fluid CEA levels, and acellular cytology as a mucinous cyst cannot be confidently excluded.

Simple Machines  

NSDL National Science Digital Library

Through a five-lesson series with five activities, students are introduced to six simple machines—inclined plane, wedge, screw, lever, pulley, wheel-and-axle—as well as compound machines, which are combinations of two or more simple machines. Once students understand about work (work = force x distance), they become familiar with the machines' mechanical advantages, and see how they make work easier. Through an introduction to compound machines, students begin to think critically about machine inventions and their pervasive roles in our lives. After learning about Rube Goldberg contraptions—absurd inventions that complete simple tasks in complicated ways—they evaluate the importance and usefulness of the many machines around them. Through the hands-on activities, students draw designs for contraptions that could move a circus elephant into a rail car, create a construction site ramp design by measuring different inclined planes and calculating the ideal vs. actual mechanical advantage of each, compare the theoretical and actual mechanical advantages of different pulley systems conceived to save a whale, build and test grape catapults made with popsicle sticks and rubber bands, and follow the steps of the engineering design process to design and build Rube Goldberg machines.

PAX-8 expression in cutaneous ciliated cysts: evidence for Müllerian origin.  

PubMed

Cutaneous ciliated cysts (CCC) are exquisitely rare, benign cystic lesions demonstrating simple, ciliated epithelial linings reminiscent of fallopian tube epithelium. Most commonly, CCC show a predilection for the lower extremities of young reproductive age women and demonstrate immunohistochemical positivity for estrogen and progesterone receptors, supporting the theory that they are derived from ectopic Müllerian rests. PAX-8 is a paired box gene, important in the development of Müllerian and thyroid organs and has utility in the identification of tumors of Müllerian, renal, and thyroid origin. Prompted by the precedent studies on PAX-8 immunohistochemical expression in tumors of Müllerian origin, this article aimed to explore the utility of this antibody in defining the histogenesis of 2 bona fide cases of CCC, both occurring in young reproductive age women. Herein, 2 prototypic index cases of CCC with strong nuclear positivity for estrogen and progesterone receptors are shown to also have positive nuclear staining for PAX-8, further supporting their likely Müllerian origin. These data support the designation of these lesions as cutaneous Müllerian cysts, distinct from potential ciliated cysts of eccrine origin. PMID:23907320

Uterine Cysts in Female Mice Deficient for Caveolin-1 and Insulin-Like 3 Receptor RXFP2  

PubMed Central

Gene mutations of insulin-like 3 (INSL3) peptide or its G protein-coupled receptor RXFP2 (relaxin family peptide receptor 2) lead to cryptorchidism. The role of INSL3 in adult females is less known, although INSL3 expression has been described in female reproductive organs. Caveolin-1 (CAV1), the main component of caveoli cell membrane invaginations, has been shown to play an important role in epithelial organization and stromal-epithelial interactions. We created a null allele of Cav1 mice by deleting its second exon through embryonic stem cell targeting. Immunohistochemical analysis demonstrated that CAV1 expression was primarily localized to endothelial blood vessel cells and the myometrium uterus, whereas the strongest expression of Rxfp2 was detected in the endometrial epithelium. By 12 months of age approximately 18% of Cav1?/? females developed single or multiple dilated endometrial cysts lined by a flattened, simple low epithelium. A deficiency for Rxfp2 on Cav1-deficient background led to more than a 2-fold increase in the incidence of uterine cysts (54–58%). Appearance of cysts led to a severe disorganization of uterine morphology. We have found that the cysts had an increased expression of ?-catenin and estrogen receptor ? in endometrial stromal and epithelial cells and increased epithelial proliferation. An analysis of simple dilated cysts in human patients for CAV1 expression did not show appreciable differences with control regardless of menstrual phase, suggesting an involvement of additional factors in human disease. The results of this study suggest a novel synergistic role of INSL3/RXFP2 and CAV1 in structural maintenance of the uterus. PMID:21467199

Aesthetic recovery of alveolar atrophy following autogenous onlay bone grafting using interconnected porous hydroxyapatite ceramics (IP-CHA) and resorbable poly-L-lactic/polyglycolic acid screws: case report  

PubMed Central

Background Onlay bone grafting techniques have some problems related to the limited volume of autogenous grafted bone and need for surgery to remove bone fixing screws. Here, we report a case of horizontal alveolar ridge atrophy following resection of a maxillary bone cyst, in which autogenous onlay bone grafting with interconnected porous hydroxyapatite ceramics (IP-CHA) and bioresorbable poly-L-lactic/polyglycolic acid (PLLA-PGA) screws was utilized. Case presentation A 51-year-old man had aesthetic complications related to alveolar atrophy following maxillary bone cyst extraction. We performed onlay grafting for aesthetic alveolar bone recovery using IP-CHA to provide adequate horizontal bone volume and PLLA-PGA screws for bone fixing to avoid later damage to host bone during surgical removal. During the operation, an autogenous cortical bone block was collected from the ramus mandibular and fixed to the alveolar ridge with PLLA-PGA screws, then the gap between the bone block and recipient bone was filled with a granular type of IP-CHA. Post-surgery orthopantomograph and CT scan findings showed no abnormal resorption of the grafted bone, and increased radiopacity, which indicated new bone formation in the area implanted with IP-CHA. Conclusion Our results show that IP-CHA and resorbable PLLA-PGA screws are useful materials for autogenous onlay bone grafting. PMID:24889647

[Intradural arachnoid cyst associated with syringomyelia: a case report].  

PubMed

An intradural arachnoid cyst is a relatively rare condition, occurring within the spinal subarachnoid space. We present the even-more rare case of an intradural arachnoid cyst associated with syringomyelia at the same spinal level. The patient was a 66-year-old man who presented with bilateral leg numbness and gait disturbance. Magnetic resonance imaging (MRI) revealed an intradural arachnoid cyst located dorsal to, and compressing, the thoracic spinal cord at the level of the 7th thoracic vertebra (Th 7). In addition, syringomyelia existed at the level of Th 8, slightly caudal to the intradural arachnoid cyst. We dissected the cyst but did not perform any surgical procedures for the syringomyelia. Post-operative MRI showed that the cyst had disappeared and the syringomyelia had spontaneously shrunk. The patient was discharged with improvement in his numbness and gait disturbance. There are a few case reports of intradural arachnoid cysts associated with syringomyelia, but recent evidence suggests that its occurrence is more common than previously thought. A combination of these two diseases is thought to be caused by blockage of cerebrospinal fluid (CSF) flow, which is also thought to cause adhesive arachnoiditis. For this reason, resection of the arachnoid cyst could improve the CSF flow and contribute to the shrinkage of syringomyelia. Furthermore, early treatment may correlate with improvement in radiological findings and neurological symptoms. PMID:24807552

We present the case of a 63 year male patient, natural from Lima. He has been in a cattle zone seven years ago. His illness had an insidious start and a progressive course; from a month ago he had malaise associated with nausea, abdominal distention and occasional vomiting; denies weight loss. In the clinical examination was lucid and stable, and without jaundice. The abdomen was soft without signs of peritoneal irritation; in the left flank there was a large mass with defined limits, painless, attached to deeper layers. Auxiliary tests: CBC: eosinophils 5.74%; the levels coagulation, biochemistry and electrolytes were normal. Total protein, albumin, bilirubin levels, aminotransferasas (ALT an AST) and alkaline phosphatase were normals. Arco V: 248 (N<22) and positive Inmunoblot to Echinococcus granulosus. Abdominal ultrasound showed two cystic formations of 161 x 95 mm and 146 x 130 mm, that moving the left kidney and spleen. Axial tomography was interpreted as a large ovoid formation (12 x 18 x 27 cm) dependent on spleen, lobed, hypodense, with rounded focal areas with less attenuation in the peripheral area; without contrast enhancement, compatible with hydatid cyst Gharbi III. The surgical intervention was a partial cystectomy plus external drainage; the surgeon found a giant splenic hydatid cyst, occupied the left hypochondrium and the left flank; had thick walls, daughter vesicles and clear liquid inside. The cystic lesion was attached to the descending colon, stomach, and left diaphargm. We present this case because the splenic hydatid cyst is rare, even less as a single site, and their prevalence does not exceed 1 %. PMID:20924431

Uncommon Locations and Presentations of Hydatid Cyst  

PubMed Central

Background: Hydatid disease (HD) is an ancient disease and even was known to Hippocrates. This disease involves all human parts and most common affected organs are liver and lungs. Incidence of unusual site is about 8-10%. The clinical picture depends upon the involved organs, its effects on adjacent structures, complications due to secondary infection, rupture, and anaphylaxis caused by hydatid cysts. Aim: The aim of this study was to find out incidence of unusual location of hydatid cyst in the human body. Materials and Methods: A retrospective study of HD was carried in a medical college between July 2007 and June 2012. A total 79 cases of HD were treated during this period. Information on clinical presentation and management were reviewed, and results presented as summary statistics. Results: Sixty one cases were of liver HD, and 11 were with hydatid lung disease. Fifty cases were with right lobe involvement, and rest 11 were with both lobe involvement. Out of 11 lung hydatid only one case was with bilateral lung involvement. Only eight cases of HD of uncommon locations and presentations were encountered during this period. First case presented with left hypochondriac mass as splenic HD, second with pelvic HD along with obstructive uropathy, third with non-functioning right kidney with bilateral psoas muscles HD, fourth with HD involving mesentery, fifth with pelvic pain due to right ovary HD, sixth with simultaneous involvement of the liver and right subdiaphragmatic region, seventh with HD of right inguinal region, and eighth with hydatid cyst of the left kidney. Even though, there was no mortality found in these patients, there was high morbidity. Conclusion: We conclude that Echinococcus granulosus can affect any organ in the body from head to toe, and a high suspicion of this disease is justified in endemic regions. Moreover, medical treatment should be given in the pre-operative period as well as in the post-operative period for 4-6 weeks. PMID:24971224

Isolated hydatid cyst of uterine cervix: A case report.  

PubMed

Hydatid disease is an endemic infection which can affect any organ, mainly the liver and lungs. Peritoneal echinococcosis is usually known to occur secondary to hepatic hydatid cyst rupture into the peritoneal cavity. An isolated cyst in the pelvic cavity is considered as primary only when there are no other hydatid cysts. Herein, we report an isolated pelvic-cervical hydatid cyst which presented without any involvement of the other abdominal organs or lungs. Our patient, a 27-year-old woman with the primary complaints of dyspareunia and chronic pelvic pain, had thin-walled large cystic mass originating from the cervix, diagnosed by ultrasonography. She underwent surgery with the most likely initial diagnosis of exophytic fibroid with cystic degeneration. Gynecologists should be aware of the possibility of isolated primary hydatid cyst of the pelvic cavity and should consider this condition in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

Rupture of echinococcal cysts: diagnosis, classification, and clinical implications.  

PubMed

The authors classify rupture of echinococcal cysts into three types: contained, communicating, and direct. Contained rupture occurs when only the parasitic endocyst ruptures and the cyst contents are confined within the host-derived pericyst. When cyst contents escape via biliary or bronchial radicles that are incorporated in the pericyst, the rupture is communicating. Direct rupture occurs when both the endocyst and the pericyst tear, spilling cyst contents directly into the peritoneal or pleural cavities or occasionally into other structures. Communicating and direct forms have more serious clinical implications than contained rupture, but even contained rupture should have prompt surgical attention to prevent it from developing into one of the other forms. Untreated communicating rupture of a liver cyst can lead to obstruction of the biliary system with a 50% mortality rate. Direct rupture may cause anaphylaxis, and it should be managed surgically, possibly with adjunctive treatment with antihelminthic drugs to decrease the possibility of metastatic hydatosis.

Introduction Adrenal cysts represent rare clinical entities. Although surgical indications are well defined, pitfalls arise from the failure to establish an accurate preoperative diagnosis. Cystic lesions of other abdominal organs especially the pancreas complicate the diagnostic field. Presentation of case We present the case of a giant adrenal cyst in a young female causing diagnostic dilemma. Imaging studies revealed a large cystic lesion of uncertain origin located between the spleen and the tail of the pancreas. It was decided to perform a laparotomy which confirmed the presence of an adrenal cyst and enucleation of the cyst was performed. Examination at one year confirmed no complications. Discussion Adrenal cysts should always be included in the differential diagnosis of cystic abdominal lesions. Conclusion When the preoperative diagnosis is uncertain, surgical intervention can be both diagnostic and therapeutic. PMID:22096737

Primary subcutaneous cyst hydatid: presentation of two cases.  

PubMed

Subcutaneous localization of an hydatid cyst is quite rare, and is found in literature in the form of case presentations. Other points worthy of attention are the lack of other foci in the majority of these cases, and the negative results of serology. In this study, two primary subcutaneous hydatid cyst cases, one in the facial area (53-year old female) and the other on the back (37-year old female), have been examined with reference to literature. In both cases, no other foci were determined, and the hydatid cyst serology was negative. When these two cases and the cases in literature are studied, it can be said that the hydatid cyst grows faster than previously known. It is noteworthy that, generally, in atypically localized cyst hydatids, there are no other foci (liver and lungs) and the serology is negative. This shows that the etiopathogenesis of the disease is not fully understood as yet. PMID:24192628

The location of hydatid cysts inside pulmonary arteries has been reported only on rare occasions in the literature and is caused, in the majority of cases, by embolization due to the rupture of hydatid cysts located in the heart; more rarely, hematogenous dissemination from a hepatic focus is the cause. We report a case of a 44-year-old patient with hydatid cysts located in both the right and left pulmonary arteries, whose first clinical reference was hemoptysis. The patient had undergone surgery because of a hepatic hydatid cyst 5 months previously. The importance of this case lies in the infrequent bilateral location in both pulmonary arteries and in the absence of intracardiac hydatid cysts. PMID:9724432

Neuroenteric cysts of the brain-comprehensive magnetic resonance imaging  

PubMed Central

Neuroenteric cysts are developmental cysts that should be differentiated from other, more common non-neoplastic cysts as well as cystic neoplasms. While these lesions may have varied imaging findings, T1 hyperintense prepontine lesion due to mucinous/proteinaceous content is characteristic. Location and imaging characteristics aid in formulating the correct diagnosis of neuroepithelial/neuroenteric cysts. Magnetic resonance spectroscopy (MRS) has the specific finding of N-Acetyl Aspartate (NAA)-like peak at 2.02 ppm which is not seen in other cystic lesions. In this study, we aim to discuss the imaging findings of these lesions on conventional and advanced MRI findings and provide radiologic-pathologic correlation. We also briefly describe the pathogenesis, embryology and radiological differential diagnoses of these cysts. PMID:24082482

Surgical treatment of sacral perineural cysts. A case report.

Most of the perineural cysts (Tarlov's cysts) are asymptomatic. They are usually diagnosed incidentally, and a specific treatment is not necessary. They should be operated on, only if they produce progressive or disabling symptoms and/or sign clearly attributable to them. Several reports have been made regarding their sign and symptom, neurological and radiological features. This is a report emphasizing on their surgical indication and surgical treatment. We reported a 48 year-old woman who underwent surgery because of the symptomatic perineural cyst. It is concluded that the total excision of the perineural cyst is not necessary and a partial resection with a resultant reduction in the cyst size results in a favourable outcome. PMID:10985157

We describe the methodology of the Bone and Soft Tissue Bank, from extraction and storage until use. Since the year 1986, with the creation of the Bone Bank in the University Clinic of Navarra, more than 3,000 grafts have been used for very different types of surgery. Bone grafts can be classified into cortical and spongy; the former are principally used in surgery to save tumour patients, in large post-traumatic reconstructions and in replacement surgery where there are massive bone defects and a structural support is required. The spongy grafts are the most used due to their numerous indications; they are especially useful in filling cavities that require a significant quantity of graft when the autograft is insufficient, or as a complement. They are also of special help in treating fractures when there is bone loss and in the treatment of delays in consolidation and pseudoarthrosis in little vascularized and atrophic zones. They are also used in prosthetic surgery against the presence of cavity type defects. Allografts of soft tissues are specially recognised in multiple ligament injuries that require reconstructions. Nowadays, the most utilised are those employed in surgery of the anterior cruciate ligament although they can be used for filling any ligament or tendon defect. The principal difficulties of the cortical allografts are in the consolidation of the ends with the bone itself and in tumour surgery, given that these are patients immunodepressed by the treatment, the incidence of infection is increased with respect to spongy grafts and soft tissues, which is irrelevant. In short, the increasingly widespread use of allografts is an essential therapeutic weapon in orthopaedic surgery and traumatology. It must be used by expert hands. PMID:16998521

Polycystic liver disease: quantitation of parenchymal and cyst volumes from computed tomography images and clinical correlates of hepatic cysts.  

PubMed

Polycystic liver disease is a common manifestation of autosomal dominant polycystic kidney disease. However, factors that regulate hepatic cystogenesis have not been defined, and the effect of cyst formation on hepatic parenchymal mass has not been studied. We validated computed tomographic methods for measuring volumes from computed tomographic images using plastic-agar models and demonstrated that measured volumes were within 10% of actual volumes. The validated methods were used to measure hepatic parenchymal, hepatic cyst and kidney volumes in 25 subjects with polycystic liver disease and nine controls without autosomal dominant polycystic kidney disease. Hepatic cyst volume varied considerably in the 25 subjects with polycystic liver disease (20 to 7,148 ml), but hepatic parenchymal volume was not altered by hepatic cysts and was similar to that of controls (polycystic liver disease vs. controls: 1,357 +/- 185 vs. 1,319 + 340 ml). Total liver volume increased linearly as cyst volume increased (slope = 1.02 +/- 0.05, r = 0.994). Nine of 18 women with polycystic liver disease had massive hepatic cysts (cyst: parenchymal volume greater than 1; range of cyst volumes from 1,354 to 7,148 ml), and the other nine had cyst volumes (20 to 399 ml) similar to men with polycystic liver disease (25 to 1,107 ml). Total kidney volume, a measure of renal cystic disease, did not correlate with either total liver volume or the volume of hepatic cysts. The data indicate that hepatic parenchymal volume is preserved in polycystic liver disease despite massive cystic involvement and that women are uniquely susceptible to massive hepatic cystic disease.

Unusual dermoid cyst in oral cavity.  

PubMed

Dermoid cysts in oral cavity are unusual lesions. Their etiology is not yet clear and can be associated with trapped cells as a result of the inclusion error resulting in the development into the ectoderm, mesoderm, and endoderm tissues. The aim of this case report is to evidence the presence of a dermoid cyst in the floor of mouth surgically removed. In the present case, the lesion showed soft consistency, floating, regular borders, smooth surface, and the same color as the adjacent mucosa, asymptomatic and measuring 4.5?×?5.5?cm in its greatest diameter. The initial diagnostic was ranula in consequence of the similarity with clinical characteristics and localization. After surgical removal lesion, a fibrotic capsule was identified with a friable material with intensive yellow color. The microscopic exam showed cystic lesion with cavity lined by squamous stratified epithelium hyperorthokeratinized. Cutaneous attachments, such as sebaceous glands and hair follicles, were present in connective adjacent tissue. Surgical intervention is elective in these situations. All dentists must have a thorough knowledge of this unusual lesion. PMID:24818032

[Thyroglossal cyst and papillary carcinoma. Management proposals].  

PubMed

The thyroid descends through the foramen cecum leaving the thyroglossal duct, which disappears between the fifth and the tenth week of pregnancy. The lack of involution of any part of this duct results in thyroglossal cyst formation. Its diagnostic approach is made by cervical ultrasound, computed tomography and magnetic resonance imaging. Approximately 1 % of the thyroglossal cyst formation contains malignant elements, and the most reported primary tumor has been papillary carcinoma. The recommended treatment for these carcinomas is controversial and it has evolved as time goes by. From Sistrunk procedure to neck dissection with total thyroidectomy and complementary therapies, such as iodine ablation and thyroid supplements, yet there is still no consensus as to the type of surgery and postoperative management it should be used to treat this carcinoma. Therapy should be applied according to each specific case, and it should be based on histological diagnosis, the invasive character of the tumor, and the lymph node affectation. In this paper we review the literature published so far with regards to the treatment of this carcinoma. PMID:25301137

Isolated calyx mistaken for a cyst: inappropriately performed catheter-directed sclerotherapy and safe removal of the catheter after selective embolization.  

PubMed

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. PMID:24692028

Combination of lumbar kyphosis, epidural lipomatosis, and perineural cyst as a cause of neurological deficit: a case report.  

PubMed

We describe the rare simultaneous occurrence of epidural lipomatosis and a perineural cyst at the same level, lumbar kyphosis, osteoporotic vertebral fractures, and neurological deficits. A 75-year-old corticosteroid-dependent female farmer presented with severe low back pain, progressive lumbar kyphosis, and inability to stand because of numbness and muscle weakness of both legs. Plain radiographs displayed markedly decreased bone density, significant lumbar kyphosis, and vertebral compression fractures of L2, L3, and L4. Magnetic resonance imaging of the lumbar spine revealed a perineural cyst at the L2-3 level, extensive epidural lipomatosis, and spinal canal stenosis. Laminectomy from L3 to L5 with resection of epidural fatty tissue restored her walking ability. We postulate that the osteoporotic fractures and epidural lipomatosis were induced by corticosteroid therapy. Preexisting degenerative lumbar kyphosis of the type commonly seen in elderly farmers could have promoted osteoporotic lumbar vertebral fractures at points where bending stress had been strongly exerted. The combination of a perineural cyst and epidural lipomatosis at the same level has not been reported previously. PMID:12486480

Subchondral bone in osteoarthritis: insight into risk factors and microstructural changes  

PubMed Central

Osteoarthritis (OA) is a major cause of disability in the adult population. As a progressive degenerative joint disorder, OA is characterized by cartilage damage, changes in the subchondral bone, osteophyte formation, muscle weakness, and inflammation of the synovium tissue and tendon. Although OA has long been viewed as a primary disorder of articular cartilage, subchondral bone is attracting increasing attention. It is commonly reported to play a vital role in the pathogenesis of OA. Subchondral bone sclerosis, together with progressive cartilage degradation, is widely considered as a hallmark of OA. Despite the increase in bone volume fraction, subchondral bone is hypomineralized, due to abnormal bone remodeling. Some histopathological changes in the subchondral bone have also been detected, including microdamage, bone marrow edema-like lesions and bone cysts. This review summarizes basic features of the osteochondral junction, which comprises subchondral bone and articular cartilage. Importantly, we discuss risk factors influencing subchondral bone integrity. We also focus on the microarchitectural and histopathological changes of subchondral bone in OA, and provide an overview of their potential contribution to the progression of OA. A hypothetical model for the pathogenesis of OA is proposed. PMID:24321104

Marfan syndrome and symptomatic sacral cyst: Report of two cases  

PubMed Central

Context Meningeal abnormalities such as dural ectasia are seen in Marfan syndrome, but spinal meningeal cysts are rarely seen. These cysts usually asymptomatic and often found incidentally on magnetic resonance imaging, large cysts may cause neurological deficits and pain secondary to nerve root compression. Design Case reports. Findings Two patients with Marfan syndrome presented with urinary symptoms secondary to dural ectasia and sacral cysts. Patient 1 had a history of low back pain, erectile dysfunction, and occasional urinary incontinence and groin pain with recent symptom worsening. He underwent L5 partial laminectomy and S1-S2 laminectomy with sacral cyst decompression. Nine weeks later, he underwent drainage of a sacral pseudomeningocele. Pain and urinary symptoms resolved, and he remains neurologically normal 2 years after surgery. Patient 2 presented after a fall on his tailbone, complaining of low back pain and difficulty urinating. Physical therapy was implemented, but after 4 weeks, urinary retention had not improved. He then underwent resection of the sacral cyst and S1-S3 laminectomy. Pain and paresthesias resolved and bowel function returned to normal. Other than needing intermittent self-catheterization, all other neurologic findings were normal 30 months after surgery. Conclusion/clinical relevance Surgical goals for sacral cysts include resection as well as closure of the dura, which can be challenging due to thinning from ectasia. Neurosurgical intervention in Marfan syndrome is associated with a high risk of dural tears and osseous complications, and should be performed only when symptoms are severe. PMID:23941798

Prevalence and fate of Giardia cysts in wastewater treatment plants.  

PubMed

The present study was conducted to review factors affecting the prevalence and concentration of Giardia in raw wastewater. The removal and inactivation efficiency of Giardia by wastewater treatment technologies was also reviewed. Data published for the prevalence of Giardia in wastewater and the removal by wastewater treatment plants was reviewed. Giardia cysts are highly prevalent in wastewater in various parts of the world, which may reflect the infection rate in the population. In 23 of 30 (76.6%) studies, all of the tested raw wastewater samples were positive for Giardia cysts at concentrations ranging from 0.23 to 100 000 cysts l(-1). The concentration of Giardia in raw wastewater was not affected by the geographical region or the socio-economic status of the community. Discharge of raw wastewater or the application of raw wastewater for irrigation may result in Giardia transmission. Activated sludge treatment resulted in a one to two orders of magnitude reduction in Giardia, whereas a stabilization pond with a high retention time removed up to 100% of the cysts from wastewater. High-rate sand filtration, ultrafiltration and UV disinfection were reported as the most efficient wastewater treatment methods for removal and disinfection of Giardia cysts. Wastewater treatment may not totally prevent the environmental transmission of Giardia cysts. The reviewed data show that a combination of wastewater treatment methods may results in efficient removal of Giardia cysts and prevent their environmental transmission. PMID:22564037

Cyst of the common bile duct in a cat.  

PubMed

A cyst of the common bile duct (CBD) is reported in a 9-year-old cat that presented with a 1-week history of anorexia, weight loss and vomiting. Diagnosis was established by ultrasound examination and laparotomy, and was ultimately confirmed by histological analysis. Chronic cholangitis and an Escherichia coli species were detected concurrently according to the histopathological findings and bile culture, respectively. The case was managed by suturing the borders of the ostium of the cyst over a stent, using a temporary cholecystostomy tube and antibiotic therapy. At 7 months following the surgery, the cat was in excellent physical condition with no clinical evidence of recurrence of cholangitis or of the cyst after ultrasonographic evaluation. According to the human literature, cysts of the CBD require treatment because of their common association with cholangitis, pancreatitis, and cystic rupture. We were unable to confirm a link between the cyst and cholangitis in this case. It is possible that detection of this anomaly was an incidental finding unrelated to bacterbilia. Histological examination of cyst tissue is mandatory for a definitive diagnosis and to differentiate it from neoplasia. This is the first description of a cyst of the CBD in the cat. PMID:20579033

Hemorrhagic colloid cyst: Case report and review of the literature  

PubMed Central

Colloid cysts are cystic lesions located at the anterior part of third ventricle, close to foramen of Monro and contain colloid material. Hemorrhage in a colloid cyst is very rare. On literature review, we found only six cases of hemorrgic colloid cyst; among them, four were diagnosed at postmortem examination. We report a rare case of a hemorrhagic colloid cyst in a young lady who presented with sudden onset severe headache and vomiting. Computed tomography (CT) scan showed isodense lesion located at foramen of Monro with hyperdense areas suggestive of hemorrhage with foraminal obstruction. The lesion was not enhancing on contrast. Magnetic resonance imaging (MRI) brain revealed a well-defined cystic mass lesion located at the foramen of Monro which was hyperintense on T1 and hypointense on T2-weighted images. Excision of the colloid cyst was performed which revealed hemorrhagic clot instead of colloid material. Histopathological examination revealed a colloid cyst with hemorrhage. We believe that this is the first such reported case of successful clinical outcome following early diagnosis and excision of a hemorrhagic colloid cyst in an adult. PMID:24403960

Cutaneous Hybrid Cyst in a Sprague-Dawley Rat  

PubMed Central

This report describes a spontaneous hybrid cyst in a Sprague-Dawley (SD) rat. A 52-week-old, male SD rat had a cutaneous cyst on the left mystacial pad. Histologically, the cyst wall showed infundibular differentiation with keratohyalin granules in the granular layer and matrical differentiation comprising basaloid epithelial cells with trichohyalin granules. The cyst cavity was filled with lamellar, flaky keratin and aggregates of shadow cells. Immunohistochemically, the infundibular-type epithelium was positive for cytokeratin (CK) AE1/AE3, CK KL1 and CK14 but negative for CK15, whereas the matrical-type epithelium was negative for all four CK isoforms examined. These immunohistochemical properties of the infundibular- and matrical-type epithelia were similar to those of the infundibulum and inferior segment of normal hair follicles, respectively. Based on these findings, the cyst was diagnosed as a hybrid cyst, comprising more than one type of cyst arising from various parts of the pilosebaceous unit. PMID:22907984

All laser surgeries were done in the Department of Reproduction, Institute of Gynecology, Karol Marcinkowski School of Medical Sciences, Poznan, Poland between September 1995 and September 1996. In the authors' opinion the use of CO2 laser is the efficient method of treatment of vaginal cysts. The most of laser procedures are doing as the one-day surgery. There are no serious postoperative complications after laser surgery.

Dinoflagellate resting cysts as factors in phytoplankton ecology of the North Sea  

NASA Astrophysics Data System (ADS)

The occurrence and distribution of dinoflagellate resting cysts were investigated at 11 locations in the south-eastern part of the North Sea. Twenty-six known cyst species and 7 unknown cyst types, which may act as seed population for planktonic dinoflagellate blooms, have been recorded for the first time in the area. The most common cysts in recent sediments were those of Scrippsiella trochoidea, Zygabikodinium lenticulatum, Peridinium dalei, Scrippsiella lachrymosa, Protoceratium reticulatum, Protoperidinium denticulatum, and P. conicum. At all stations, S. trochoidea dominated the cyst assemblages with a maximal abundance of 1303 living cysts/cm3 in the uppermost half centimetre. Cysts of the potentially toxic dinoflagellates Alexandrium cf. excavatum and A. cf. tamarense were scarce. In the upper 2-cm layer of sediment, dinoflagellate cysts were found in concentrations of 1.8 up to 682 living cysts/cm3. Empty cysts constituted 22 56% of total cyst abundance. The comparative distribution of the cysts showed a general increase in abundance from inshore sites to the offshore area, whereby sandy stations exhibited the lowest cyst abundance and diversity. The wide distribution of living and empty cysts of Scrippsiella lachrymosa suggests that its motile form, which has not been officially recorded in the area until now, is a common plankton organism in German coastal waters. The relatively high abundance of cysts in recent sediments demonstrates the potential importance of benthic resting stages for the initiation of dinoflagellate blooms in the study area.

Epithelial Cyst in the Posterior Triangle of the Neck: Atypical Branchial Cyst or Cystic Lymph Node Metastasis?  

PubMed Central

We report the case of a 66-year-old man with a cervical neck mass located behind the left sternocleidomastoid muscle. To exclude malignancy, a full workup, including clinical, radiological, and cytological examination, was performed but failed to provide a definitive diagnosis. Histological analysis following excisional biopsy revealed a benign epithelial cyst, consistent with an atypically located branchial cyst. We describe an approach to the management of these neck masses and discuss several theories of the etiology of branchial cysts and how they may come to be abnormally located. PMID:24523976

Management of liver hydatid cysts – Current perspectives  

PubMed Central

Human hydatid disease or cystic echinococcosis (CE), caused by the larval form of cestode Echinococcus granulosus still continues to a common problem in health care environments as different as Europe/North America and resource poor countries of the South America and the East. The Liver is the most frequently parasatized organ in humans. While ultrasonography remains the main diagnostic tool, computed tomography and serology improve the accuracy of diagnosis in Liver hydatid cysts (LHC). Although surgery is the only modality applicable over the entire spectrum of the disease, systemic chemotherapy and percutaneous drainage have evolved as alternative therapies in the last three decades. Various laparoscopic techniques have also been described for safe and optimal management of this entity. In this paper, we review the current management procedures of LHC with particular emphasis on the evidence base and setting specific problems. PMID:24532894

Cervical Thymic Cyst in an Adult  

PubMed Central

Cervical thymic cysts (CTCs) are unusual lesions, representing only 1% of cystic cervical masses. Diagnosis of this condition in adults is even rarer. We report a 34-year-old female who presented with asymptomatic progressively growing left-sided neck swelling. Neck ultrasound (US) showed a large cystic lesion with septation, compressing the ipsilateral vessels. Magnetic resonance imaging (MRI) confirmed the US findings. Surgical excision was performed which subsequently showed findings consistent with CTC. CTC in adult is extremely rare, with few reported cases identified in the literature. Thymic gland anomalies in the neck are the consequences of an arrest in the descent of the gland, sequestration of the thymic tissue, or failure of involution. The diagnosis of this condition is rarely done prior to surgical excision. The clinical presentation, radiologic imaging, surgical findings, and histologic appearance are all essential components to make the correct diagnosis of this very rare differential diagnosis of cystic lateral neck swelling.

Proliferating trichilemmal cyst with focal calcification.  

PubMed

A 64-year-old man presented with a superficial, well-demarcated, skin-colored tumor on the left posterior scalp that measured 4 x 5 x 6 cm. The tumor was nearly hairless, rubbery, non-tender, and mobile over the underlying subcutaneous tissues. The lesion had grown slowly since arising approximately 30 years ago. Treatment options were declined in the past. However, with relatively more rapid growth over the past five years, the nodule began to cause intermittent pain and interfere with the patient's ability to lie on his back. The patient denied a history of similar lesions in himself or his family. A biopsy specimen showed a ruptured proliferating trichilemmal cyst with focal calcification. Complete excision is recommended for all benign proliferating variants owing to their potential for locally aggressive behavior and malignant transformation. PMID:19061624

Nonhost Root Penetration by Soybean Cyst Nematode  

PubMed Central

A total of 66 plants in 50 species were inoculated with eggs and juveniles of soybean cyst nematode, Heterodera glycines. Roots were stained and observed for penetration and development of the nematode. Twenty-six plants were not penetrated; twenty-three were penetrated, but there was no development of the nematode; eight were penetrated with some nematode development; two were penetrated and had considerable nematode development, but few nematodes, if any, matured; and seven were penetrated with many nematodes maturing. The penetration of nonhosts may imply some susceptibility and that populations eventually would build up on the penetrated plants. Plants not penetrated may be useful as rotation plants because no reproduction would occur. PMID:19290137

Abscess formation within a Rathke's cleft cyst  

PubMed Central

We report and discuss the rare case of a pituitary abscess forming within a Rathke's cleft cyst (RCC). A 66-year-old gentleman presented with visual deterioration and symptoms suggestive of hypopituitarism. The patient underwent transsphenoidal debulking of the lesion whereupon purulent material was discovered. Histological examination was suggestive of RCC together with numerous neutrophils characteristic of abscess. Microbiological culture of the material grew Staphylococcus aureus. The patient was treated for a RCC abscess and received antibiotics and endocrine replacement therapy. The patient has been followed up for 2 years without recurrence. Although uncommon, we recommend the consideration of RCC abscess as a differential diagnosis of a pituitary mass lesion as clinical presentation and radiological assessment are not specific in identifying these lesions preoperatively.

[Bone anchored hearing aids (BAHA)].  

PubMed

Bone anchored hearing aids (BAHA) achieve optimal acoustic coupling by means of direct bone conduction via an osseointegrated percutaneous titanium implant. Currently this system has a record of over 30 years of clinical application and reliability. Patients with bilateral hearing loss with air-bone gaps will benefit from bilateral BAHA fitting. Likewise, unilateral conductive hearing loss with normal hearing on the other side can be treated with a BAHA. New developments in this field include the BAHA Intenso and also novel implant systems, such as the Epiplating system by Medicon, the alpha system by Otomag and the OBC system by Otorix. Due to the advantages of the BAHA system (possibility of preoperative testing, simple surgery without the risk of inner ear damage, MRI compatibility, etc.), the BAHA will keep its important role in hearing rehabilitation even in the era of other partially and totally implantable hearing devices.

Bone marrow: the workhorse organ.  

PubMed

Bone marrow accounts for 3% to 6% of body weight and is dispersed throughout bone. In a healthy adult, bone marrow produces approximately 500 billion new blood cells daily to maintain steady-state levels in the peripheral circulation. Its output is measured using the complete blood count (CBC), which is arguably the most frequently ordered laboratory test in the clinical milieu. Hematopoiesis starts with hematopoietic stem cells that differentiate and mature into any of the three different types of mature blood cells. A simple CBC can rule out, confirm, or direct attention to anemia, cancer, infection, acute hemorrhage states, toxin exposure, allergies, immunodeficiencies, or adverse drug reactions. Interpreting CBCs depends on reference values from the laboratory that processes the blood sample. Since reference intervals are formulated based on a younger, much healthier population, data specific to elderly people are limited. PMID:23315278

Oxygen-rich hierarchical porous carbon derived from artemia cyst shells with superior electrochemical performance.  

PubMed

In this study, three-dimensional (3D) hierarchical porous carbon with abundant functional groups is produced through a very simple low-cost carbonization of Artemia cyst shells. The unique hierarchical porous structure of this material, combining large numbers of micropores and macropores, as well as reasonable amount of mesopores, is proven favorable to capacitive behavior. The abundant oxygen functional groups from the natural carbon precursor contribute stable pseudocapacitance. As-prepared sample exhibits high specific capacitance (369 F g(-1) in 1 M H2SO4 and 349 F g(-1) in 6 M KOH), excellent cycling stability with capacitance retention of 100% over 10?000 cycles, and promising rate performance. This work not only describes a simple way to produce high-performance carbon electrode materials for practical application, but also inspires an idea for future structure design of porous carbon.

[An epidermoid cyst derived from an intrapancreatic accessory spleen].  

PubMed

A 43-year-old female patient had high levels of CA19-9 marker; an abdominal ultrasound revealed a cyst. Further investigations with computed tomography (CT), magnetic resonance imaging, and endoscopic ultrasound CT identified a multilocular cystic lesion on the pancreatic tail. An abnormal wall was noted, and different signal strengths were measured in each cyst. Thus, a mucinous cystic tumor was diagnosed, and distal pancreatectomy combined with splenectomy was performed. During the surgery, we identified a multilocular pancreatic cyst with internal bleeding at its distal end. The lesion was ultimately diagnosed as an epidermoid cyst of an intrapancreatic accessory spleen. This diagnosis was based on the histological observation that the vascular construction of the cystic wall was equivalent to that of the spleen, and that its internal tissue was covered by squamous epithelium.

[Chance finding of foetal and neonatal ovarian cysts on echography].  

PubMed

Cystic abnormalities of the adnex were found by chance in 2 baby girls, one aged 2.5 months and the other aged 2 months. Both had been born dysmaturely and the abnormalities were found on echographic investigation carried out for suspected urinary-tract infection. On monitoring investigation one month later, the abnormalities had become smaller and some time later had disappeared altogether. With the increasing use of ultrasound, ovarian cysts are being detected more often in the foetus and neonate. The majority of these cysts are benign functional follicular cysts and resolve spontaneously. The decision to perform surgery depends on the clinical symptoms and appearance on ultrasound. Large uncomplicated cysts can be managed by antenatal or postnatal aspiration in order to prevent torsion and the subsequent loss of the adnex. PMID:17203692

Clinical Outcomes of Percutaneous Endoscopic Surgery for Lumbar Discal Cyst  

PubMed Central

Objective Discal cyst is rare and causes indistinguishable symptoms from lumbar disc herniation. The clinical manifestations and pathological features of discal cyst have not yet been completely known. Discal cyst has been treated with surgery or with direct intervention such as computed tomography (CT) guided aspiration and steroid injection. The purpose of this study is to evaluate the safety and efficacy of the percutaneous endoscopic surgery for lumbar discal cyst over at least 6 months follow-up. Methods All 8 cases of discal cyst with radiculopathy were treated by percutaneous endoscopic surgery by transforaminal approach. The involved levels include L5-S1 in 1 patient, L3-4 in 2, and L4-5 in 5. The preoperative magnetic resonance imaging and 3-dimensional CT with discogram images in all cases showed a connection between the cyst and the involved intervertebral disc. Over a 6-months period, self-reported measures were assessed using an outcome questionaire that incorporated total back-related medical resource utilization and improvement of leg pain [visual analogue scale (VAS) and Macnab's criteria]. Results All 8 patients underwent endoscopic excision of the cyst with additional partial discectomy. Seven patients obtained immediate relief of symptoms after removal of the cyst by endoscopic approach. There were no recurrent lesions during follow-up period. The mean preoperative VAS for leg pain was 8.25±0.5. At the last examination followed longer than 6 month, the mean VAS for leg pain was 2.25±2.21. According to MacNab' criteria, 4 patients (50%) had excellent results, 3 patients (37.5%) had good results; thus, satisfactory results were achieved in 7 patients (87.5%). However, one case had unsatisfactory result with persistent leg pain and another paresthesia. Conclusion The radicular symptoms were remarkably improved in most patients immediately after percutaneous endoscopic cystectomy by transforaminal approach. PMID:22737300

Humeral head cysts: association with rotator cuff tears and age.  

PubMed

The objective of this study was to retrospectively evaluate the prevalence of the cystic changes at rotator cuff footprint on proximal humeral tuberosities and investigate their relationship with rotator cuff tears and patient age. Magnetic resonance (MR) images of 657 patients who underwent shoulder arthroscopy for treatment of rotator cuff disorders were reviewed to localize the cystic changes at anterior (supraspinatus insertion) and posterior (infraspinatus insertion) aspects of greater tuberosity (GT) and lesser tuberosity (subscapularis insertion). Preoperative MR reports as well as cyst size and locations on MR images were correlated with arthroscopic records of rotator cuff pathology (tear type, size, location and tendon involvement) and patient age. The prevalence of cystic changes was 9.1% (60 patients) in the study population. Anterior GT cysts were found in 56% of patients and were strongly associated with full-thickness (p<.001) and articular-sided partial-thickness rotator cuff tears (p=.02). Posterior GT and lesser tuberosity cysts were found in 27 and 17% of patients, respectively, and were not significantly related to rotator cuff tears, although there was an increased trend of posterior cysts in patients with infraspinatus tears (p=.09). A significant relation was found between patient age and the cyst size (p=.01), while none of the cyst localizations were statistically related to age. Anterior GT cysts were more common in this patient group and demonstrated a strong association with rotator cuff disorders regardless of age. Posterior GT and lesser tuberosity cysts were less common and showed no association with rotator cuff pathology or patient age. PMID:23748696

Mucous and ciliated cell metaplasia in epithelial linings of odontogenic inflammatory and developmental cysts.  

PubMed

The incidence of mucous and ciliated cells in epithelial linings was examined among odontogenic inflammatory cysts (radicular cysts) and developmental cysts (dentigerous and primordial cysts). Mucous cells were found in 20.8% of all cysts examined, while ciliated cells were found in 11.4%; however, ciliated cells were always accompanied by mucous cells. The incidence of mucous cells in radicular cysts and dentigerous cysts and that of ciliated cells in radicular cysts was higher in the maxilla than in the mandible, while the incidence of mucous cells in primordial cysts and that of ciliated cells in dentigerous cysts and primordial cysts was higher in the mandible than in the maxilla. The present results regarding mucous cells and ciliated cells in the epithelial linings of intraosseous odontogenic cysts indicate a metaplasic origin, but the cause and biological significance of this phenomenon is not known. Mucous cells were present in the surface layer of epithelial linings, and intraepithelial gland-like structures lined with mucous cells were observed in the hyperplastic regions of epithelial linings of several radicular and dentigerous cysts. Such gland-like structures lined by mucous cells in the thickened epithelial lining, which have not been demonstrated previously, resembled the glandular structures of "glandular odontogenic cysts".

Arachnoid cyst of the velum interpositum originating from tela choroidea  

PubMed Central

Background: Arachnoid cysts originating from the velum interpositum are very rare, and their existence as a clinicopathologic entity remains controversial. We report a case of a patient with an arachnoid cyst of the velum interpositum presenting with memory disturbance, focusing on the anatomical origin of the lesion and the physiological mechanisms causing memory disturbance. Case Description: A 65-year-old man with a large cystic lesion in the velum interpositum experienced progressive memory disturbance and enlargement of the lesion 6 months before referral to our institution. Neuropsychological evaluation on admission demonstrated severe memory disturbance. Radiological examination did not reveal hydrocephalus, but the bilateral fornices and thalami were compressed by the cyst. The patient underwent endoscopic cystoventriculostomy via the frontal horn of the right lateral ventricle through a frontal burr hole. Histopathology of the sample was consistent with that of an arachnoid cyst, and the endoscopic findings suggested that the cyst originated from the tela choroidea, which covers the velum interpositum. The symptoms resolved after surgery with significant improvement in neuropsychological test scores. Conclusion: Arachnoid cysts of the velum interpositum are rare but distinct clinicopathologic entities that originate from the tela choroidea. The lesions can cause memory disturbance without hydrocephalus due to compression of the fornices and thalami, but this can be reversed by surgery. PMID:23226606

Laparoscopic management of pedicle torsion of adnexal cysts.  

PubMed

Pedicle torsion of adnexal cysts results from the increased weight of cysts, longer length of the ovarian and suspensory ligaments or ovarian teratoma. Color doppler ultrasonography is particularly important for detecting suspected cyst torsion. Laparoscopy is becoming more important in the early diagnosis and treatment of adnexal cyst torsion due to its advantages, such as its minimally invasive nature, reduced acute stress reaction and facilitation of direct observation of intra-abdominal lesions. The present study analyzed 28 cases of laparoscopic torsion surgery. The laparoscopic conservative surgery rate was 75% and loss of endocrine function and fertility was avoided. Since the torsion duration is the only variable factor for avoiding oophorectomy, laparoscopic exploration should be performed as soon as possible when pedicle torsion of an adnexal cyst is suspected. Detorsion while retaining ovarian function did not increase the risk of thromboembolism and laparoscopic surgery was minimally invasive with faster recovery times and minimal impact on fertility. Furthermore, the study showed that the laparoscopic management of pedicle torsion of adnexal cysts is safe and reliable with the retention of ovarian endocrine and reproductive function.

Acute Myelopathy Caused by a Cervical Synovial Cyst  

PubMed Central

Synovial cysts of the cervical spine, although they occur infrequently, may cause acute radiculopathy or myelopathy. Here, we report a case of a cervical synovial cyst presenting as acute myelopathy after manual stretching. A 68-year-old man presented with gait disturbance, decreased touch senses, and increased sensitivity to pain below T12 level. These symptoms developed after manual stretching 3 days prior. Computed tomography scanning and magnetic resonance imaging revealed a 1-cm, small multilocular cystic lesion in the spinal canal with cord compression at the C7-T1 level. We performed a left partial laminectomy of C7 and T1 using a posterior approach and completely removed the cystic mass. Histological examination of the resected mass revealed fibrous tissue fragments with amorphous materials and granulation tissue compatible with a synovial cyst. The patient's symptoms resolved after surgery. We describe a case of acute myelopathy caused by a cervical synovial cyst that was treated by surgical excision. Although cervical synovial cysts are often associated with degenerative facet joints, clinicians should be aware of the possibility that these cysts can cause acute neurologic symptoms.

Prenatal Diagnosis and Postnatal Findings of Bronchogenic Cyst  

PubMed Central

Bronchogenic cysts arise from abnormal buds from the primitive esophagus and tracheobronchial tree, which do not extend to the site where alveolar differentiation occurs. Bronchogenic cysts are typically unilocular mucus field lesions arising from posterior membranous wall of the air way. The prenatal diagnosis usually is realized by two-dimensional ultrasound showing the large unilocular cystic image in the chest fetus. The prenatal percutaneous aspiration can reduce the risk of heart compression and permit better respiratory conditions to newborn. We present a case of a primiparous pregnant 23 year-old-woman prenatal ultrasound showed a large unilocular cyst in the left hemithorax with compression of the normal left lung tissue and contralateral mediastinal shift. This cyst was percutaneously aspirated without subsequent reaccumulation of fluid. The newborn did not have respiratory distress and the computed tomography scan confirmed the finding of a fluid-filled cyst in the left chest. The chest X-ray showed the displacement of the heart and the mediastinum from the left to the right. The prenatal diagnosis of bronchogenic cyst is very important to assess the degree of the compression of the normal lung and the mediastinum shift. Furthermore, the prenatal diagnosis permits planning delivery in the tertiary hospital with multidisciplinary team because of the risk of respiratory distress. PMID:23762726

Surgical management and radiological characteristics of bronchogenic cysts.  

PubMed

Forty-two patients with bronchogenic cysts were treated over a 30-year period (1962 to 1991). The location was mediastinal in 37 and intrapulmonary in 5. Cysts were symptomatic in 21 patients (50%) and complications occurred in 11 (26%). The complications included infection in 5 patients, hemorrhage into the cyst in 2 patients, dysphagia due to esophageal compression in 2, adenocarcinoma arising from a bronchogenic cyst in an 8 1/2-year-old girl, and an esophagobronchopleurocutaneous fistula as a result of previous incomplete resection in 1 patient. Magnetic resonance imaging has been found to provide specific diagnostic information about bronchogenic cysts. All but 2 patients were treated with complete excision. One patient was managed by observation and another had drainage of the cyst by mediastinoscopy. Complications of treatment occurred in only 2 patients. One had a minor wound infection and the other had Clostridium difficile enterocolitis. Only 4 patients were lost to follow-up. No late complication or recurrence developed in those patients having complete excision. We recommend complete excision in most instances to confirm the diagnosis, relieve symptoms, and prevent complications. PMID:8431062

The management of bone metastases requires a multidisciplinary staff to include systemic and local treatments like radiotherapy, surgery or interventional radiology (IR). Patients are often fragile. Imaging allows safe guidance to create "mini-invasive" procedures under adequate anesthesia. Patients' selection is important. If the goal is pain relief, cementoplasty provides a very effective bone consolidation and pain control. Simple and low-risk, vertebroplasty is the technique of choice in case of lytic bone metastases with spinal fracture risk or after failure of analgesic radiotherapy. If the medical project is curative, the tumor ablation procedures are realised through thermic or embolic techniques. After 60°C, the heat induces a coagulative necrose. Under -20°C, the cold leads to destroy the tissues. The major advantage of the cryotherapy is the predictibility of the ablation zone due to the well-visualized ice ball on perprocedural images. This technique is much more adapted to spare the nervous structures closed to the metastasis. The development of these new techniques of IR will treat bone metastases earlier, sometimes asymptomatic and thus improves the quality of life in patients with bone metastases. PMID:24153025

Disorders of Bone Remodeling  

PubMed Central

The skeleton provides mechanical support for stature and locomotion, protects vital organs, and controls mineral homeostasis. A healthy skeleton must be maintained by constant bone modeling to carry out these crucial functions throughout life. Bone remodeling involves the removal of old or damaged bone by osteoclasts (bone resorption) and the subsequent replacement of new bone formed by osteoblasts (bone formation). Normal bone remodeling requires a tight coupling of bone resorption to bone formation to guarantee no alteration in bone mass or quality after each remodeling cycle. However, this important physiological process can be derailed by a variety of factors, including menopause-associated hormonal changes, age-related factors, changes in physical activity, drugs, and secondary diseases, which lead to the development of various bone disorders in both women and men. We review the major diseases of bone remodeling, emphasizing our current understanding of the underlying pathophysiological mechanisms. PMID:20936937

Ruptured popliteal cyst diagnosed by ultrasound before evaluation for deep vein thrombosis.  

PubMed

Most popliteal cysts are asymptomatic. However, cysts may rupture, resulting in pain and swelling of the leg that could also arise from other diseases, including deep vein thrombosis, lymphedema, cellulitis, and tear of a muscle or tendon. Therefore, it is difficult to diagnose a ruptured popliteal cyst based on only a patient's history and physical examination. Musculoskeletal ultrasound has been regarded as a diagnostic tool for ruptured popliteal cyst. Here, we describe a patient who was rapidly diagnosed as ruptured popliteal cyst by ultrasonography. Therefore, ultrasound could be used to distinguish a ruptured popliteal cyst from other diseases in patients with painful swollen legs before evaluation for deep vein thrombosis. PMID:25566485

Endobronchial Ultrasound: A Useful Tool in the Diagnosis of Bronchogenic Cyst  

PubMed Central

Diagnosis of bronchogenic cysts is possible with computed tomography, where the cysts are seen usually as well-circumscribed lesions of water density. However, many of the cysts have a soft-tissue density thus rendering them indistinguishable from neoplasms. In this article, we describe a case of bronchogenic cyst presenting as soft-tissue mass that was evaluated and diagnosed by endobronchial ultrasound (EBUS). We discuss the ultrasound image characteristics of the cyst and its histopathology findings. EBUS seems to be a valuable tool in the diagnosis of bronchogenic cysts and also enables their complete aspiration. PMID:24605253

Dinosaur Bone Experiments  

NSDL National Science Digital Library

This activity features two connected hands-on activities about dinosaur bones. Using chicken or turkey bones and regular household items, learners explore the scientific process of studying fossilized bones. By exposing the bones to vinegar or heat, learners begin to understand how paleontologists use chemical processes to study the bones of animals long dead and gone. Use this bone-themed activity around the Thanksgiving holiday and repurpose some leftovers.
