Simple bone cyst of mandible mimicking periapical cyst.  

PubMed

Simple bone cysts (SBC) are pseudocysts occurring less commonly in the maxillofacial region. The uncertain and unclear etiopathogenesis led to numerous synonyms to refer this particular cyst. These cysts are devoid of an epithelial lining and are usually empty or contain blood or straw-colored fluid. In jaws initially it mimics a periapical cyst and later can lead to cortical bone expansion warranting for radical approach, which is seldom required. SBC is predominantly diagnosed in first two decades of life. Here we report a case of solitary bone cyst mimicking a periapical cyst of a mandibular molar in a 37-year-old patient. PMID:24765458

Aneurysmal bone cyst of the ethmoid bone.  

PubMed

A 90-year-old woman presented with headache and diplopia, and a mass in the nasal cavity and paranasal sinuses was found on CT scan. The patient underwent examination under anaesthesia showing a mass arising from the ethmoid, apparently from the nasal septum. Biopsies taken showed an aneurysmal bone cyst. The patient opted against surgery and has been managed conservatively. A second CT scan 4 years later showed significant increase in size. PMID:24706701

Aneurysmal bone cyst associated with fibrous dysplasia.  

PubMed

We report the clinicopathologic features of a 22-year-old patient with aneurysmal bone cyst and fibrous dysplasia of the orbit. The patient was evaluated clinically with computed tomography of the orbit before surgery. An orbital biopsy specimen was examined histologically with conventional light microscopy. The lesion was treated with combined neurosurgical and orbital intervention. Clinical evaluation revealed axial and inferior displacement of the globe. Computed tomography revealed a cystic mass in the superotemporal left orbit with adjacent bone erosion. "Ground-glass" thickening of the adjacent frontal bone and sphenoid bone was observed. Microscopic examination showed fibrous stroma with giant cells and hemosiderin-laden macrophages with adjacent trabeculae of woven bone and osteoblast cells. A fronto-orbital craniotomy was performed, the cystic cavity was excised, and the hyperostotic bone was debulked. After treatment, the globe position and patient appearance have improved. There has been no sign of recurrence of the aneurysmal bone cyst. Aneurysmal bone cyst should be considered in patients with fibrous dysplasia that has a cystic component, or in patients with fibrous dysplasia who present with sudden expansion of their lesion.

[Sacral metastasis simulating aneurysmal bone cyst].  

PubMed

Cystic spinal lesions with characteristic patterns, such as the presence of haematic fluid-fluid levels (H-FFL), have been associated with many tumoral lineages, more frequently with aneurysmal bone cyst (ABC) and exceptionally with metastasis. We present the case of a 60-year-old man with the finding of a sacral cystic bone lesion with H-FFL, with initial suspicion of ABC and confirmed diagnosis of metastasis. The case presented is, to our knowledge, the second case published of spinal cystic bone metastasis with H-FFL pattern with unknown primary tumour at the time of diagnosis and the only one that received resective surgical treatment, achieving pulmonary and metastatic disease control with good quality of life after 1 year of follow up.

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

Management of a simple renal cyst in a complex patient.  

PubMed

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

Alcohol sclerotherapy in the treatment of symptomatic simple renal cysts.  

PubMed

The aim of this study was to evaluate the results of percutaneous drainage with single-session alcohol sclerotherapy in the treatment of symptomatic simple renal cysts. Thirty patients (16 men and 14 women, average age 54,7+/-11,3 years) with simple renal cysts were treated by ultrasound guided percutaneous aspiration and single-session alcohol sclerotherapy. Patient demographics, clinical characteristics, treatment outcome and complications were analyzed. Average reduction of cyst volume was 91,2%. Complete and partial resolution occurred in 10 (33%) and 14 (47%) cysts, respectively. Six cases were defined as failure with reduction of cyst volume <80%. Flank pain improved in all patients, regardless of complete or partial resolution. Minor complications occurred in 8 patients. The hospital stay was one day for all patients. Treatment of simple renal cysts is indicated when the cysts are sufficiently large and cause complaints or when associated with complications. Percutaneous treatment with alcohol sclerotherapy of benign renal cysts can be performed safely and effectively. PMID:19125704

[Are simple renal cysts another manifestation of prelithiasis in infancy?].  

PubMed

Simple renal cysts are uncommon lesions in paediatric patients. In the absence of hypokalaemia or an increase in the production of NH+, the cause of simple renal cysts is unknown. Hepler, in 1930, suggested that they may be caused by a tubular obstruction. We prospectively studied the presence of hypercalciuria or hypocitraturia as well as the family history of urolithiasis in a group of children diagnosed sonographically with simple renal cysts. The average age of the 22 patients (12M, 10F) was 6.04 +/- 2.9 years at the time of diagnosis. The ultrasound examination had been requested due to urinary tract infection, abdominal pain, haematuria or other disorders. The cysts were slightly more frequent on the left side (54.5%). All were located in the upper kidney pole. 14 patients were found to have hypercalciuria and/or hypocitraturia (hypercalciuria n = 11, 50%). Thirteen families had history of renal stones. The metabolic abnormalities associated with calculi in children and/or family history of stones were present in 19 families (86.3%). Our hypothesis is that both entities, renal cysts, and genetic predisposition to kidney stones, are related. PMID:20514100

Extradural Dermoid Cyst of Mastoid Bone: A Case Report  

PubMed Central

Dermoid cysts of the head and neck are rare congenital benign tumors. According to the literature they represent about seven percent of all dermoids and less than one percent of all intracranial neoplasms. Extradural dermoid cysts are very rare. We report a case of intracranial extradural dermoid cyst of mastoid bone. We believe that this is the second documented extradural dermoid cyst, the first case reported in the literature (Ammirati et al., 2007) was in close relation to the petrous apex but ours is in close relation to mastoid antrum. Hearing loss was the only clinical presentation in this case, while neurological symptoms were the main presenting symptoms in the first reported case. We present our management of this rare case with respect to the clinical, radiological, histopathological, and surgical aspects and conclude that dermoid tumors, though rare, need to be included in differential diagnosis of middle ear lesions.

Juvenile ossifying fibroma with aneurysamal bone cyst: a case report.  

PubMed

The fibro osseous lesions of the jaws represent a diverse group of entities that are characterized by replacement of normal bone by a fibrous connective tissue matrix, with in which varying amounts of osteoid, immature and mature bone and in some instances, cementum like material are deposited. Fibro osseous lesions of the jaws include developmental (hamartomatous) lesions, reactive or dysplastic processes and neoplasms. Juvenile ossifying fibroma (JOF) is a unique fibro osseous neoplasm. It has 2 histopathological variants (1) Trabecular juvenile ossifying fibroma (TrJOF) and (2) Psammomatoid juvenile ossifying fibroma (PsJOF) with TrJOF affecting the jaws of children. Only 20% of the patients are over 15 years of age. JOF is more common in maxilla than mandible. Origin in extragnathic locations is extremely rare. It presents as an asymptomatic progressive, rapid expansion of jaws. Radiographically, tumour is well circumscribed, along with lack of continuity with adjacent bone, cortical expansion & perforation. Histopathologically it consists of a cell rich fibrous stroma with bundles of cellular osteoid and bone trabeculae without osteoblastic rimming, and aggregates of giant cells. It has a recurrence rate of 30-58%. Long standing lesions shows cystic changes. Aneurysmal bone cyst is the most common complication. Here we present a case report of 16 yr old female patient with clinical, radiographic & histopathological features of Trabecular JOF with Aneurysmal bone cyst. PMID:25478458

Optic nerve compression due to aneurysmal bone cyst.  

PubMed

A 10-year-old boy developed loss of central vision in both eyes due to compression of the optic nerves by a mass arising from the sphenoid and ethmoid sinuses. Histopathologic examination of biopsy specimens showed a fibrous matrix composed of spindle-shaped cells interspersed with small and large channels, characteristic of an aneurysmal bons cyst. One year after partial excision of the intracranial and extracranial portions fo the lesions, vision had returned to nearly normal levels. Aneurysmal bone cysts rarely involve the orbits or other cranial bones to produce ocular signs and symptoms. However, since this lesion probably represents reactive proliferation of bony tissues, rather than neoplasia, the prognosis for vision and life is good. PMID:588110

Successful NBCA embolization of a T2 aneurysmal bone cyst.  

PubMed

Surgically accessible aneurysmal bone cysts (ABC) have traditionally been treated with curettage. Selective arterial embolization was initially proposed as a preoperative adjuvant to reduce peroperative bleeding. Currently, the role of embolization has been extended to the definitive treatment of aneurysmal bone cyst of the spine in children, as well as to other locations in the skeleton. The authors describe the technique in a 15-year-old girl with a T2 aneurysmal bone cyst. Digital subtraction angiography was performed for tumor vascular mapping, followed by selective arterial embolization with N-butyl 2 cyanoacrylate (NBCA). Because of persistent local pain, repeat embolization was done at 8 months. Pain relief and progressive ossification of the lesion were now observed. At 4-year follow-up, the patient was asymptomatic, with complete ossification of the lesion. Selective arterial embolization (SAE) is a minimally invasive, safe and effective procedure for the permanent occlusion of the pathological feeding vessels of spinal ABC. It should be considered as the treatment of choice for lesions difficult to access with surgery, especially in young patients. Careful pre-embolization vascular mapping of the lesion, operator's experience and use of NBCA are the keys to success. PMID:24873097

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. PMID:25620988

Painful scoliosis due to superposed giant cell bone tumor and aneurysmal bone cyst in a child.  

PubMed

Giant cell bone tumors are the most common precursor lesions of aneurysmal bone cysts (ABCs) developing secondarily. In giant cell bone tumors containing an explicit ABC component, the observation of the solid component of the giant cell bone tumor plays a critical role in the separation of the primary ABC. In general, ABC cases together with giant cell tumors in the bone are diagnosed histopathologically. The combination of giant cell bone tumor with superposed ABC and that of painful scoliosis with backache is rarely seen in children. In this case study, we discussed the diagnosis and the treatment of a giant cell tumor and superposed an ABC present in the fifth lumbar spine in a pediatric patient admitted to our clinic with a complaint of acute scoliotic back pain.

PubMed Central

Aneurysmal bone cyst is a benign tumor-like bone lesion. This report concerns a 43 year-old male patient diagnosed with a primary aneurysmal bone cyst of his right patella. His main presentation was anterior knee pain. The patient was treated with arthroscopic excisional biopsy of the cyst and curettage, followed by filling the cavity with bone cement at a second stage. During the 5-year follow-up, the patient remained symptom free, with a normal range of motion. The arthroscopic approach is a less-invasive procedure with low morbidity and enabled us to determine which site should be going through.

Treatment of a unicameral bone cyst in a dog using a customized titanium device  

PubMed Central

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

Intrahepatic biliary dilatation caused by a small simple hepatic cyst: report of a case.  

PubMed

Abstract Biliary obstruction caused by small simple cysts is very rare. We present a case of biliary dilatation caused by a simple cyst with a 4-cm diameter. The patient was a 75-year-old woman referred to our hospital for evaluation of a cystic tumor associated with peripheral biliary duct dilatation in the left segment of the liver. Computed tomography and magnetic resonance imaging showed that the cyst probably communicated with the intrahepatic bile duct. Malignant tumors, including intrahepatic papillary neoplasms of the bile duct, could not be ruled out; therefore, we performed surgery with the patient's consent. Histopathologic examination of the resected liver showed that the cystic lesion was a simple cyst. The finding that even small simple cysts can obstruct the biliary tract is important for the management of cystic lesions of the liver. PMID:25437583

The effect of ethanol sclerotherapy of 5 minutes duration on cyst diameter and rat ovarian tissue in simple ovarian cysts  

PubMed Central

Objectives To examine the effect of 95% ethanol sclerotherapy (EST) administered over 5 minutes on cyst diameter and ovarian tissue in experimentally induced simple ovarian cysts in a rat model. Materials and methods In order to induce ovarian cysts, unilateral total salpingectomy was performed in regularly menstruating adult female Wistar albino rats (n=20) between 12 and 14 weeks of age and weighing between 200 and 220 g. One month after the procedure, the abdominal cavity was opened and 14 rats (70%) were found to have developed macroscopic cysts. Rats with macroscopic cysts (n=14) were assigned into two groups in a prospective and single-blinded manner: group 1 (G1) (n=7), control rats; and group 2 (G2) (n=7), 5-minute EST 95% group. Cyst diameter was measured and recorded for each rat. In G2, after whole cyst fluid was aspirated the cystic cavity was irrigated with 95% ethanol, approximately equal to half of the aspirated cyst volume, after which an interval of 5 minutes was allowed and same amount was re-aspirated and the abdominal cavity was closed. One month after this procedure, abdominal cavities were reopened and intra-abdominal adhesion scoring was performed in both groups. Cyst diameter was measured for each rat, and the right ovary was removed, fixed in 10% formaldehyde, and transported to the laboratory. A histologic assessment of the ovarian tissues was performed under light microscopy following staining with hematoxylin and eosin. Mann–Whitney U-test was used for statistical analysis. A P-level less than 0.05 was considered significant. Results In comparison with G1, there was a statistically significant reduction in the mean ovarian cyst dimensions in G2, while there were no significant differences between the two groups with respect to total number of follicles. Again, a significant increase in apoptotic activity and germinal epithelial degeneration was observed in G2 as compared to G1. The two groups were similar in terms of adhesion formation. Conclusion Although 95% EST results in a reduction in the size of simple ovarian cysts, this effect seems to be achieved at the expense of ovarian tissue injury.

Symptomatic Abdominal Simple Cysts: Is Percutaneous Sclerotherapy with Hypertonic Saline and Bleomycin a Treatment Option?  

PubMed Central

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

Cyst's volumes and the reduction rate (%) were calculated in each evaluation. Results. No pain or complications were noted. A significant cyst's volume reduction was documented over time (P < 0.001). On the 12th month 17 cysts disappeared and two displayed a 98.7% and 68.9% reduction, respectively. Conclusion. This percutaneous approach constitutes a very promising nonsurgical alternative for patients with symptomatic simple cyst, without complications under proper precautions, leading to eliminating the majority of cysts.

Aneurysmal bone cysts of the spine: treatment options and considerations.  

PubMed

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

Sagittal split ramus osteotomy for aneurysmal bone cyst of the mandibular condyle.  

PubMed

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.

Percutaneous Alcohol Sclerotherapy of Simple Hepatic Cysts. Results From a Multicentre Survey in Italy  

PubMed Central

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

Role of puncture and aspiration in expectant management of simple ovarian cysts: a randomised study.  

PubMed Central

OBJECTIVES: To assess the potential of expectant management for simple ovarian cysts diagnosed by transabdominal or transvaginal ultrasonography. To compare the results of needle aspiration with those achieved with simple observation. DESIGN: Randomised trial. SETTING: Hospital department of obstetrics and gynaecology. SUBJECTS: 278 women with simple cysts randomly allocated to simple observation (143) or ultrasound guided fine needle aspiration (135) between 1990 and 1994. MAIN OUTCOME MEASURES: Resolution of cyst or development of malignancy. RESULTS: After six months 269 were available for follow up. The rate of resolution was 46% (59/128) with aspiration and 44.6% (63/141) with observation. Only the diameter of the cyst (P < 0.0001) was a significant independent prognostic factor for resolution in a multivariate analysis. Age and treatment had no significant effect. One woman was subsequently found to have borderline malignant changes on histopathological examination. Her cyst was detected by transabdominal ultrasonography. CONCLUSIONS: Expectant management for up to six months does not cause risks for the patients and allows spontaneous resolution in over a third of cases, avoiding the costs and risks of unnecessary surgery. Aspiration does not provide better results than simple observation. PMID:8916695

Benign occipital unicameral bone cyst causing lower cranial nerve palsies complicated by iophendylate arachnoiditis  

PubMed Central

A 20 year old girl presented with a history of neck and occipital pain for six weeks, which was found to be due to a unicameral bone cyst of the left occipital condylar region. The differential diagnosis of bone cysts in the skull is discussed. Six months after the operation, the patient again presented with backache due to adhesive arachnoiditis. The latter was believed to have arisen as a result of a combination of spinal infective meningitis and intrathecal ethyl iodophenyl undecylate (iophendylate, Myodil, Pantopaque). The nature of meningeal reactions to iophendylate and the part played by intrathecal corticosteroids in relieving the arachnoiditis in the present case are discussed. Images

Simple hepatic cyst causing inferior vena cava thrombus  

PubMed Central

INTRODUCTION Thrombosis of the inferior vena cava (IVC) is governed by Virchow's triad of stasis of blood flow, endothelial damage and hypercoagulability. Causes may be secondary to malignancy, congenital anomalies or other infrequent events such as external compression. We present a case of external compression of the IVC leading to extensive thrombus burden secondary to a benign hepatic cyst. PRESENTATION OF CASE A 72 year old African American female presented to the emergency department with new onset shortness of breath, right lower extremity weakness and swelling. CT imaging demonstrated multiple hepatic cysts compressing the IVC, leading to extensive clot burden. Treatment with heparin drip was initiated without resolution of her symptoms. Transcatheter mechanical thrombectomy and tPA infusion was performed. After 24 h, swelling and weakness were nearly resolved. The patient was bridged to therapeutic low molecular weight heparin in preparation for surgery. DISCUSSION Management of IVC thrombosis has typically been with a heparin drip and transition to oral anticoagulants. Thrombolysis has been shown to promote complete clot lysis more often than compared to standard anticoagulant therapy. In addition, venous patency was better maintained. CONCLUSION We feel that the added benefit of short term effects of improved venous patency and long term benefits of less post thrombotic syndrome, catheter based tPA administration and mechanical thrombectomy for thrombus offers an adjuvant treatment in the setting of large clot burden refractory to standard treatment.

An evaluation of transvaginal ultrasound-guided aspiration of simple adnexal cysts.  

PubMed

We carried out this clinical study to evaluate the benefits the risks of transvaginal ultrasound-guided aspiration in a group of patients. The study group consisted of 22 premenapausal women who were detected as having benign adnexal cysts, based on ultrasound appearances. Before the procedure, all patients were evaluated thoroughly by pelvic examination, transvaginal ultrasound and serum measurements of CA-125. Oestradiol CA-125, follicle stimulating hormone, luteinising hormone and progesterone were analysed in aspirated cystic fluids as well as cytological evaluation. It was concluded that measurements of follicle stimulating hormone, luteinising hormone, oestradiol and progesterone concentrations in cystic fluid had no prognostic significance. But CA-125 levels over 55 iu/ml were likely to predict the recurrence of the cysts. Cytological examination of the aspirated cystic fluids revealed that 21 cysts were benign functional cysts, but one was serous cystadenoma. We observed recurrence following aspiration in five patients (22.7%) who were followed for 6 months. Patients with simple ovarian cysts will benefit from transvaginal ultrasound-guided aspiration by being saved from surgery and its related complications. However, its use should be limited to those masses that appear to be completely cystic with well-defined borders, because of the risk of the intra-abdominal spillage of the contents of complicated cysts.

Micro-CT evaluation of bone defects: applications to osteolytic bone metastases, bone cysts, and fracture.  

PubMed

Bone defects can occur in various forms and present challenges to performing a standard micro-CT evaluation of bone quality because most measures are suited to homogeneous structures rather than ones with spatially focal abnormalities. Such defects are commonly associated with pain and fragility. Research involving bone defects requires quantitative approaches to be developed if micro-CT is to be employed. In this study, we demonstrate that measures of inter-microarchitectural bone spacing are sensitive to the presence of focal defects in the proximal tibia of two distinctly different mouse models: a burr-hole model for fracture healing research, and a model of osteolytic bone metastases. In these models, the cortical and trabecular bone compartments were both affected by the defect and were, therefore, evaluated as a single unit to avoid splitting the defects into multiple analysis regions. The burr-hole defect increased mean spacing (Sp) by 27.6%, spacing standard deviation (SpSD) by 113%, and maximum spacing (Spmax) by 72.8%. Regression modeling revealed SpSD (?=0.974, p<0.0001) to be a significant predictor of the defect volume (R(2)=0.949) and Spmax (?=0.712, p<0.0001) and SpSD (?=0.271, p=0.022) to be significant predictors of the defect diameter (R(2)=0.954). In the mice with osteolytic bone metastases, spacing parameters followed similar patterns of change as reflected by other imaging technologies, specifically bioluminescence data which is indicative of tumor burden. These data highlight the sensitivity of spacing measurements to bone architectural abnormalities from 3D micro-CT data and provide a tool for quantitative evaluation of defects within a bone.

Cystic giant sacral schwannoma mimicking aneurysmal bone cyst : a case report and review of literatures.  

PubMed

To present a rare case of a cystic giant schwannoma of the sacrum mimicking aneurysmal bone cyst (ABC). A 54-year-old man visited our institute complaining left leg weakness and sensory change for several years. 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

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

Devastating Ischemic Stroke Following Selective Arterial Embolization of a Large Chest Wall Aneurysmal Bone Cyst.  

PubMed

Aneurysmal bone cysts (ABC) are benign bone lesions found in children and young adults. Rarely, these lesions can arise from ribs, and there is disagreement on the best treatment because of proximity to vital structures. Frequently, surgeons remove ABC with en bloc resection. Selective arterial embolization has been used as an adjunct to surgery, or rarely as the primary treatment. We report a case of embolic stroke complicating embolization of a rib ABC, likely from the presence of collateral circulation between the mass and vertebral artery. Caution should be taken when performing embolization of lesions in this location because of potential complications. PMID:25222058

Intraspinal dural-based primary osteoblastoma with aneurysmal bone cyst-like change.  

PubMed

Osteoblastoma is a benign bone-forming neoplasm that occurs commonly in the posterior elements of the spine and the sacrum. However, so far there has been no report of intradural osteoblastoma described in the literature. We present a unique case of intraspinal dural-based osteoblastoma with aneurysmal bone cyst-like change without evidence of vertebral involvement. An 11-year-old Chinese girl presented with a 3-month history of gradually progressive back pain and a weakness of both lower limbs. Thoracic MRI revealed a well-demarcated subdural mass at the T5 level with heterogeneous enhancement. Histologically, the tumor was found to be attached to the dura and composed of numerous osteoid spicules and trabecular bone with diffusely scattered osteoclast-type, multinucleated giant cells. Ectactic blood vessels and blood-filled cystic spaces were also observed. A diagnosis of primary intraspinal dural-based osteoblastoma with aneurysmal bone cyst-like change was made. To our best knowledge, this is possibly the first case of primary osteoblastoma arising from meninges. Meningeal osteocartilaginous tumors are rare, with obscure histogenesis. The differential diagnosis of osteoblastoma in unusual locations is difficult and the confirmation of diagnosis should be cautiously made. Awareness of dural-based osteoblastoma and its histological features is important to avoid a diagnostic pitfall caused by histological similarities to other intra-craniospinal lesions with osteoid differentiation or bone formation.

Collagenous nodule mixed simple cyst and hemangioma coexistence in the liver  

PubMed Central

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

Femoral Nerve Injury as a Complication of Percutaneous Simple Renal Cyst Sclerotherapy with Ethanol: A Case Report  

PubMed Central

Simple renal cysts are benign, common, and often asymptomatic disease in old age, sometimes treated with ethanol sclerotherapy. We report a case of iatrogenic femoral nerve injury following percutaneous injection of ethanol into a renal cyst under sedation. The percutaneous injection was guided by sonography. At the end of the procedure, the cyst ruptured so the patient progressed to loss of consciousness due to alcohol intoxication. Ethanol was damaged to the femoral nerve, so patient was developed with limping, numbness, and weakness in anteromedial aspect of the right thigh. To the best of our knowledge, this is the first report of femoral nerve injury caused by percutaneous simple renal cyst sclerotherapy with ethanol. This rare event has not been previously described, Physicians should be aware of the possibility of this complication. PMID:22489246

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

Sclerotherapy for Simple Cysts with Use of Ethanolamine Oleate: Preliminary Experience  

SciTech Connect

We evaluated the efficacy of ethanolamine oleate (EO) as a sclerosing agent for a symptomatic hepatic or renal cyst. Seven patients with symptomatic hepatic (n = 3) or renal cysts (n = 4) were treated by sclerotherapy with EO. The cyst size in the greater diameter ranged from 6 to 13 cm. The cyst was punctured under ultrasound guidance, and after all of the cyst's content was aspirated, an iodized contrast agent was injected to check the absence of communication between the cyst and biliary tree, urinary tract, or vessels. Then, the solution of ethanolamine oleate-iopamidol mixture (EOI) of 10% of the volume of the cyst's content was injected via catheter. After 30 min, the injected EOI was aspirated completely before catheter removal. A follow-up computed tomography scan was performed at 1 and 3 months after treatment. The volume of the cyst and its reduction rate was calculated. In addition, symptoms and complications were assessed. The volume of the cyst ranged from 64 to 636 ml (mean: 328 ml) before treatment. Three months after treatment, it ranged from 2 to 50 ml (mean: 15ml) and the reduction rate of the cyst's volume was more than 90% on average. Symptoms caused by the cyst disappeared in all cases and no major complication was encountered. Although two patients had a low-grade fever after sclerotherapy, it was easily controlled. It is suggested that the sclerotherapy with EO might be a safe, effective, well-tolerated treatment for symptomatic hepatic or renal cysts.

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

Structural and functional reconstruction after resection of aneurysmal bone cyst of the fifth metatarsal: a case study.  

PubMed

We report a case of a primary benign bone tumor (aneurysmal bone cyst [ABC]) involving the distal portion of the fifth metatarsal, identified in an adolescent. The tumor, histologically identified as an ABC with reparative giant cell reaction, became symptomatic. Treatment included resection, followed by reconstruction of the fifth metatarsal using grafts of autologous bone with preservation of function in the metatarsophalangeal joint. The basis for selecting this form of treatment is discussed, as well as the natural history of ABC and giant cell reparative granuloma. Restoration of form and function is illustrated by this case study with a 23-month follow-up. PMID:9677085

Serial endovascular embolization as stand-alone treatment of a sacral aneurysmal bone cyst.  

PubMed

Aneurysmal bone cysts (ABCs) are destructive cystic lesions of the bone and are common in children. They are expansile in nature and, therefore, may become symptomatic. These have traditionally been treated surgically; but recently, endovascular embolization has shown promise as a stand-alone therapy. The authors describe a case of an ABC highlighting the effectiveness and efficiency of endovascular treatment. A 16-year-old boy was referred for a 4-month history of radiating back pain and urinary hesitancy. Findings from his neurological examination were normal, but he had problems ambulating because of pain. Magnetic resonance imaging and CT scanning showed a cystic mass in the sacrum; a biopsy was performed and diagnosis of ABC was confirmed. Treatment options were then discussed with the family. The patient underwent 2 endovascular embolizations in approximately 1 month: Onyx 18 was involved in the first session, and N-butyl cyanoacrylate glue was used in the second session. After the first treatment, the patient experienced a dramatic decrease in pain and concomitant improvement in function. The patient went from being mildly symptomatic after the first treatment to completely asymptomatic after the second treatment. Clinical and radiographic follow-up obtained at 2, 6, and 18 months after initial treatment revealed the patient to be asymptomatic with progressive ossification. Endovascular treatment can be effective in treating symptomatic cases of ABC in which surgery would carry significant risk.

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

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

Ovarian cysts in newborns.  

PubMed

Before the introduction of ultrasonography (US), ovarian cysts in newborns were thought to be rare. With the extended use of real-time US, prenatal detection has increased. There is still considerable controversy regarding the best treatment of these neonatal findings. A total of 27 instances in 24 consecutive newborns of antenatally-diagnosed ovarian cysts were reviewed for US data, management, and outcome to assess the ante- and postnatal evolution of the cyst and establish appropriate therapy. The cysts detected during pregnancy were studied by repeated postnatal US studies. In 10 children (2 with bilateral cysts) the cyst evolved spontaneously toward regression. Fourteen patients were operated upon; 10 had complex and 4 (in 1 bilateral) had simple cysts. Cystectomy was employed when possible to preserve the ovarian parenchyma (3 cases); in the remaining cases oophorectomy was performed. Histologically, the cysts were of follicular origin or necrosis made a diagnosis impossible. US was found to be a helpful diagnostic tool for simple ovarian cysts, but could not reliably distinguish between benign and malignant tumors if a sonographically complex lesion was present. Based on our experience, surgical management of ovarian cysts should be reserved to complex masses. Simple cysts can be monitored safely by close US follow-up; surgery is indicated if the cyst fails to regress after several months or becomes symptomatic. PMID:11315281

Targeting receptor-activator of nuclear kappaB ligand in aneurysmal bone cysts: verification of target and therapeutic response.  

PubMed

Aneurysmal bone cyst (ABC) is a benign tumor of bone presenting as a cystic, expansile lesion in both the axial and appendicular skeleton. Axial lesions demand special consideration, because treatment-related morbidity can be devastating. In similar lesions, such as giant cell tumor of bone (GCTB), the receptor-activator of nuclear kappaB ligand (RANKL)-receptor-activator of nuclear kappaB (RANK) signaling axis is essential to tumor progression. Although ABC and GCTB are distinct entities, they both contain abundant multinucleated giant cells and are osteolytic characteristically. We hypothesize that ABCs express both RANKL and RANK similarly in a cell-type specific manner, and that targeted RANKL therapy will mitigate ABC tumor progression. Cellular expression of RANKL and RANK was determined in freshly harvested ABC samples using laser confocal microscopy. A consistent cell-type-specific pattern was observed: fibroblastlike stromal cells expressed RANKL strongly whereas monocyte/macrophage precursor and multinucleated giant cells expressed RANK. Relative RANKL expression was determined by quantitative real-time polymerase chain reaction in ABC and GCTB tissue samples; no difference in relative expression was observed (P > 0.05). In addition, we review the case of a 5-year-old boy with a large, aggressive sacral ABC. After 3 months of targeted RANKL inhibition with denosumab, magnetic resonance imaging demonstrated tumor shrinkage, bone reconstitution, and healing of a pathologic fracture. Ambulation, and bowel and bladder function were restored at 6 months. Denosumab treatment was well tolerated. Post hoc analysis demonstrated strong RANKL expression in the pretreatment tumor sample. These findings demonstrate that RANKL-RANK signal activation is essential to ABC tumor progression. RANKL-targeted therapy may be an effective alternative to surgery in select ABC presentations.

Ossifying trichilemmal cyst.  

PubMed

Although a trichilemmal cyst is a relatively common benign cutaneous condition and ossification has been observed within many cutaneous lesions to our knowledge, the association between ossification and trichilemmal cyst has not been previously reported. We describe for the first time the case of a trichilemmal cyst with marked osseous metaplasia arising on the scalp of a 46 year-old woman. Microscopically the lesion showed the typical features of a trichilemmal cyst with the finding of intra-extraluminal foci of calcification and the exceptional feature of mature bone formation. No areas of mature cartilage were observed near the focus of ossification. The cutaneous bone may have been directly formed from osteogenic stromal elements without a cartilaginous precursor (membranous or mesenchymal ossification). The dystrophic calcification might also contribute to the bone-forming process. PMID:22042263

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.

Management of Renal Cysts  

PubMed Central

Background and Objectives: Renal cysts have a high prevalence in the general population, and their estimated incidence increases with age. Renal cyst aspiration (usually with sclerotherapy) or open/laparoscopic decortication is a generally effective and safe method in the treatment of symptomatic simple renal cysts. The success rates of laparoscopic decortication and percutaneous aspiration-sclerotherapy were compared to assist in the decision making for the procedure. Methods: A total of 184 patients with symptomatic simple renal cysts were treated with either laparoscopic decortication in 149 cases or percutaneous aspiration-sclerotherapy in 35 cases. The follow-up period was approximately 35 months, and the symptomatic and radiologic success rates of the 2 techniques were compared retrospectively. Results: Laparoscopic decortication was found to have high success rates, a low recurrence rate, and minimal morbidity. Percutaneous aspiration-sclerotherapy is an outpatient procedure with a minimally higher recurrence rate. Conclusion: When a symptomatic cyst is encountered and treatment of the cyst is indicated, laparoscopic decortication is a more efficient method that offers better results than percutaneous aspiration-sclerotherapy.

Ethylene oxide gas sterilization: a simple technique for storing explanted skull bone. Technical note.  

PubMed

The authors evaluated the effectiveness of a simple technique using ethylene oxide (EtO) gas sterilization and room temperature storage of autologous bone grafts for reconstructive cranioplasty following decompressive craniectomy. The authors retrospectively analyzed data in 103 consecutive patients who underwent cranioplasty following decompressive craniectomy for any cause at the University of Illinois at Chicago between 1999 and 2005. Patients with a pre-existing intracranial infection prior to craniectomy or lost to follow-up before reconstruction were excluded. Autologous bone grafts were cleansed of soft tissue, hermetically sealed in sterilization pouches for EtO gas sterilization, and stored at room temperature until reconstructive cranioplasty was performed. Cranioplasties were performed an average of 4 months after decompressive craniectomy, and the follow-up after reconstruction averaged 14 months. Excellent aesthetic and functional results after single-stage reconstruction were achieved in 95 patients (92.2%) as confirmed on computed tomography. An infection of the bone flap occurred in eight patients (7.8%), and the skull defects were eventually reconstructed using polymethylmethacrylate with satisfactory results. The mean preservation interval was 3.8 months in patients with uninfected flaps and 6.4 months in those with infected flaps (p = 0.02). A preservation time beyond 10 months was associated with a significantly increased risk of flap infection postcranioplasty (odds ratio [OR] 10.8, p = 0.02). Additionally, patients who had undergone multiple craniotomies demonstrated a trend toward increased infection rates (OR 3.0, p = 0.13). Data in this analysis support the effectiveness of this method, which can be performed at any institution that provides EtO gas sterilization services. The findings also suggest that bone flaps preserved beyond 10 months using this technique should be discarded or resterilized prior to reconstruction. PMID:17695404

Extraneural rupture of intraneural ganglion cysts.  

PubMed

Rupture of simple (extraneural) cysts such as popliteal cysts (Baker's cysts) is a well-known occurrence. The purpose of this report is to introduce the similar occurrence of extraneural rupture of peroneal and tibial intraneural cysts in the knee region, describe the associated magnetic resonance imaging (MRI) findings, and identify risk factors. There was MRI evidence of rupture in 20 of 38 intraneural cases reviewed, mainly in the region of the fibular head and popliteal fossa. Ruptured intraneural cysts and simple cysts share these MRI findings: T2 hyperintense fluid within surrounding intermuscular fascial planes and enhancement with intravenous contrast consistent with inflammation. The mean maximal diameter of the ruptured intraneural cysts was statistically significantly smaller than that of the unruptured cysts. The authors believe that extraneural rupture of an intraneural cyst is due to increased intraarticular pressures transmitted within the cyst and/or elevated extrinsic pressure delivered to the cyst, such as by trauma, akin to the etiology of rupture of extraneural ganglion cysts.

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. PMID:25540600

Thornwaldt cysts.  

PubMed

Thornwaldt cysts are rare and benign congenital cysts in the region of the pharyngeal bursa, formed by a communication between the notochord and the nasopharyngeal endoderm. They result from a mechanical obstruction, inflammation, or abscess of the pharyngeal bursa. They are superficial to the superior constrictor muscle and covered by the nasopharyngeal mucous membrane. Most cases are asymptomatic, and patients may rarely present symptoms such as nasal obstruction, foreign body sensation, hearing loss, and periodic halitosis. Therefore, they are often accidentally diagnosed on MRI. Asymptomatic cysts do not require treatment, whereas symptomatic cases require surgical intervention by endonasal or transoral approach. Marsupialization is the procedure of choice to avoid recurrences. The aim of this article is to present and discuss 2 cases of Thornwaldt cysts. PMID:25148637

Syringomyelia Associated with a Spinal Arachnoid Cyst  

PubMed Central

While syringomyelia is not a rare spinal disorder, syringomyelia associated with a spinal arachnoid cyst is very unusual. Here, we report a 62-year-old man who suffered from gait disturbance and numbness of bilateral lower extremities. Spinal magnetic resonance imaging (MRI) showed the presence of a spinal arachnoid cyst between the 7th cervical and 3rd thoracic vertebral segment and syringomyelia extending between the 6th cervical and 1st thoracic vertebral segment. The cyst had compressed the spinal cord anteriorly. Syringomyelia usually results from lesions that partially obstruct cerebrospinal fluid flow. Therefore, we concluded that the spinal arachnoid cyst was causing the syringomyelia. After simple excision of the arachnoid cyst, the symptoms were relieved. A follow-up MRI demonstrated that the syringomyelia had significantly decreased in size after removal of the arachnoid cyst. This report presents an unusual case of gait disturbance caused by syringomyelia associated with a spinal arachnoid cyst. PMID:19516954

Biliary cysts.  

PubMed Central

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

A simple and safe technique for longitudinal bone marrow aspiration in cynomolgus and rhesus macaques.  

PubMed

Longitudinal bone marrow aspirates were obtained aseptically from the humerus of 36 rhesus and 6 cynomolgus macaques by using a 20G spinal needle, introduced through the bone close to the greater tuberosity. All samplings were performed without complications, and the animals showed no signs of pain or infections. The amount of total bone marrow cells obtained from each aspiration varied, in part due to animal-to-animal variation, but the yields were not affected by the sampling frequency or the length of time between each aspiration. The frequency of plasma cells in the bone marrow of each animal was also fairly stable over several longitudinal samplings while a greater, age-dependent, variation was observed between different animals.

Primary Intraosseous Hydatid Cyst of Femur  

PubMed Central

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

Simple diagnostic method to assess the available bone for immediate implant placement in an extracted socket.  

PubMed

The success rate of immediate tooth replacement has been well documented in the literature. To achieve long-term success of dental implants, evaluation of the dimensions of the resorbing alveolar process must be accurate because an implant should be surrounded by at least 1 mm of bone. To minimize facial gingival recession, an intact labial bony plate along with an osseous-gingival relationship of 3 mm on the facial aspect of the failing tooth has been suggested. This article mentions a technique wherein the amount of available labial and palatal bone of an extracted socket can be assessed by using the extracted tooth that is to be replaced with an endosseous implant and a ridge mapping procedure without reflecting the flap.

To our knowledge, intradural cyst following epiduroscopy has not been reported in the literature. A 65-year-old woman with back pain related with previous lumbar disc surgery underwent endoscopic epidural neuroplasty and nerve block, but her back pain much aggravated after this procedure. Postoperative magnetic resonance imaging revealed a large intradural cyst from S1-2 to L2-3 displacing the nerve roots anteriorly. On T1 and T2-weighted image, the signal within the cyst had the same intensity as cerebrospinal fluid. The patient underwent partial laminectomy of L5 and intradural exploration, and fenestration of the cystic wall was accomplished. During operation, the communication between the cyst and subarachnoid space was not identified, and the content of the cyst was the same as that of cerebrospinal fluid. Postoperatively, the pain attenuated immediately. Incidental durotomy which occurred during advancing the endoscope through epidural space may be the cause of formation of the intradural cyst. Intrdural cyst should be considered, if a patient complains of new symptoms such as aggravation of back pain after epiduroscopy. Surgical treatment, simple fenestration of the cyst may lead to improved outcome. All the procedures using epiduroscopy should be performed with caution. PMID:23323173

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.

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

[Needle aspiration of ovarian cysts. Our experience].  

PubMed

80 patients underwent ultrasound guided cyst puncture of ovarian cysts. Six patients were pregnant and in four of them needle aspiration was executed through the transvaginal tract. The sediment aspirated was examined by a cytologic method and when possible it was also correlated to a histological test. Technique and results have been dealt with. No relevant complication was found. Finally, the echoguided (induced) needle aspiration is a simple and safe method to treat benign ovarian cysts in fertile women. It is particularly advisable in pregnancy and in patients for whom both laparascopy and traditional surgery are not practicable. PMID:7885611

Transvaginal ultrasound-guided aspiration of benign ovarian cysts.  

PubMed

In our study, we evaluate the diagnostic and therapeutic efficacy of transvaginal ultrasound-guided aspiration of benign ovarian cysts in selected patients. A total of 46 women with benign ovarian cysts were referred to our outpatient clinic. The aspirated fluid was collected and sent for cytological analysis. All women were re-evaluated at 1, 3 and 6 months after the procedure. The cytological analysis was negative for malignancy in all cases. Our study showed an overall recurrence rate for ovarian cysts of 39.1%. Women with endometriotic ovarian cysts have an increased incidence of recurrence, 62.5% (n = 5), in comparison with serous cysts, 35.2% (n = 12) and serous-haemorrhagic cysts, 15% (n = 1), ?(2) = 9.913, df = 2, p = 0.007. The results of our study reveal that transvaginal ultrasound-guided aspiration of benign ovarian cysts is a simple, safe and effective procedure. PMID:24483623

[The simultaneous appearance and treatment of diffuse maxilla and mandible cyst with autotransplantatum. Case report].  

PubMed

The authors have observed 3 simultaneously but independently occurring cysts in the mandible and the maxilla at a 45 years old male patient. A plum sized follicular cyst around the non erupted maxillary # 23 canine and a bean sized follicular cyst around the mandibular # 33 tooth in residual retention and also an infectious, diffuse root cyst developed around the # 35 retained root was found in the mandibular corpus. The surgical extraction of the # 23, 33 residual retention canines, the # 35 retained root and the excision of the cysts were performed in intubation narcosis by two medical teams. For the filling up of the cyst cavities cortical cancellous bone blocks and particulated trabecular bone grafts were used harvested from the coxa. In the case of the infectious mandibular cyst the author's have also used local antibiotic perfusion. This complex therapy resulted in a successful recruitment within a short period of time.

Primary Hydatid Cyst in Gastrocnemius Muscle  

PubMed Central

Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced cyst rupture or after release of viable parasite material during invasive treatment procedures. Primary muscle hydatidosis is extremely uncommon, because implantation at this site would require passage through the filters of the liver and lung. Intramuscular hydatid cyst can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We present an unusual case of a primary hydatid cyst found in the popliteal fossa of the right knee of a 52-year-old woman, presenting as an enlarging soft-tissue tumor for 6 months associated with pain. The mass initially was diagnosed to be Backer?s cyst by ultrasonography, but later it was confirmed postoperatively through histopathological studies to be due to hydatid disease. In regions where hydatidosis is endemic, hydatid cyst should be included in the differential diagnosis of any unusual muscular mass. PMID:24027387

Orthokeratinised odontogenic cyst mimicking periapical cyst.  

PubMed

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

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

Nasopalatine Duct Cyst  

PubMed Central

The nasopalatine cyst is the most common epithelial and nonodontogenic cyst of the maxilla. The cyst originates from epithelial remnants from the nasopalatine duct. The cells may be activated spontaneously during life or are eventually stimulated by the irritating action of various agents (infection, etc.). It is different from a radicular cyst. The definite diagnosis should be based on clinical, radiological, and histopathological findings. The treatment is enucleation of the cystic tissue, and only in rare cases a marsupialisation needs to be performed. A case of a nasopalatine duct cyst in a 35-year-old male is reviewed. The typical radiologic and histological findings are presented. PMID:24307954

Hydatid Cyst of Spleen: A Diagnostic Challenge  

PubMed Central

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

Management of Symptomatic Sacral Perineural Cysts  

PubMed Central

Background There has been no consensus on the optimal treatment of symptomatic sacral perineural cysts. Most previous reports concerning the management methods were either sporadic case reports or a series of limited cases. This study is to further optimize the management for patients with symptomatic sacral perineural cysts by analyzing the outcomes of a cohort of patients who were treated with different strategies. Methods and Findings We reviewed the outcomes of 15 patients with symptomatic sacral perineural cysts who were managed by three different modalities from 1998 through 2010. Six patients underwent microsurgical cyst fenestration and cyst wall imbrication. Seven patients underwent a modified surgical procedure, during which the cerebrospinal fluid leak aperture was located and repaired. Two patients were treated with medication and physical therapy. Outcomes of the patients were assessed by following up (13 months to 10 years). All of the six patients treated with microsurgical cyst fenestration and cyst wall imbrication experienced complete or substantial relief of their preoperative symptoms. However, the symptoms of one patient reappeared eight months after the operation. Another patient experienced a postoperative cerebrospinal fluid leakage. Six of the seven patients treated with the modified surgical operation experienced complete or substantial resolution of their preoperative symptoms, with only one patient who experienced temporary worsening of his preoperative urine incontinence, which disappeared gradually one month later. No new postoperative neurological deficits, no cerebrospinal fluid leaks and no recurrence were observed in the seven patients. The symptoms of the two patients treated with conservative measures aggravated with time. Conclusions Microsurgical operation should be a treatment consideration in patients with symptomatic sacral perineural cysts. Furthermore, the surgical procedure with partial cyst removal and aperture repair for prevention of cerebrospinal fluid leakage seemed to be more simple and effective. PMID:22768183

Anterior Cervical Arachnoid Cyst  

PubMed Central

This report is composed of two patients with anteriorly located cervical intradural arachnoid cyst and review of 24 cases in Englishlanguage literature. Both of our patients were in the first two decades of life with neck pain and motor weakness. With suspicious diagnosis of anterior arachnoid cyst surgery was carried out in both cases, though laminectomy in one and laminoplasty in the other. The cyst wall was widely fenestrated with subsequent subtotal excision of the cyst. Both cases had good long-term outcome. The review disclosed male predominance. 73% of the patients were diagnosed within the first two decades of life. Neck pain and motor weakness were the dominant signs and symptoms of this pathology. Magnetic resonance imaging showing a cerebrospinal fluid (CSF) containing cyst was the best mode of diagnosis. Wide cyst fenestration with waying CSF into subarachnoid cyst was the most appropriate and applied surgery with optimal outcome. PMID:23741550

Diverse arachnoid cyst morphology indicates different pathophysiological origins  

PubMed Central

Background There are few, limited, and to some extent contradictory, reports on the cellular and subcellular morphology of arachnoid cysts. In the literature cyst membranes are described as similar to, or as vastly different from, normal arachnoid membranes. Methods This paper reports electron microscopic analyses of symptomatic cysts from 24 patients (12 males and 12 females; age 10–79), that underwent fenestration surgery. Fourteen cysts were located in the middle cranial fossa (temporal), one in the interpeduncular cistern, five in the posterior fossa, and four were overlying the frontal cortex. Results Microscopic findings confirmed the diverse nature of this clinical condition. Twelve cyst walls resembled normal arachnoid, four had a conspicuous core of dense fibrous tissue with a simple epithelial lining, and the remaining aberrant cysts exhibited non-arachnoid luminal epithelia with plentiful microvilli and/or cilia, and also nervous tissue components in the wall. The possible identity and origin of various cyst types are discussed. We hypothesize that cysts are formed mostly at an early stage of embryonic development, as a teratological event. Conclusions Cysts with various epithelial linings and extracellular components most likely have different barrier properties and fluid turnover characteristics. Further studies are needed to elucidate relations between cyst morphology, fluid composition, pathogenesis, and clinical behaviour including growth rate and relapse tendency. PMID:24581284

Epidermoid cyst of the floor of the mouth  

PubMed Central

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

Extradural Dermoid Cyst Located in the Lateral Sphenoid Ridge  

PubMed Central

Dermoid cysts are rare congenital tumors that occur primarily at the midline at a characteristic intradural location. However, dermoid cysts located at extradural and lateral regions have been rarely reported until now. In the present study, the authors demonstrate the unusual instance of an intracranial extradural dermoid cyst at the lateral sphenoid ridge. A 53-year-old woman admitted because of progressive headache and dizziness. The patient had no neurologic deficits, and magnetic resonance imaging with no contrast enhancement revealed a mass at the right sphenoid ridge. The mass was accompanied with sphenoid bone erosion visible on computed tomography. The patient underwent right pterional craniotomy, and the tumor including the capsule was totally resected. Presence of a dermoid cyst was confirmed with histopathological examination. The patient had no complications during the postoperative period. This study suggests that dermoid cyst should be considered for differential diagnosis of extradural and lateral intracranial masses. PMID:24926471

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

The popliteal cyst.  

PubMed

A popliteal cyst, originally called Baker's cyst, is a synovial fluid-filled mass located in the popliteal fossa. The most common synovial popliteal cyst is considered to be a distension of the bursa located beneath the medial head of the gastrocnemius muscle. Usually, in an adult patient, an underlying intra-articular disorder is present. In children, the cyst can be isolated and the knee joint normal. The anatomy, etiopathogenesis, clinical presentation, differential diagnosis, imaging and treatment modalities of the popliteal cyst are presented. The authors try to answer some questions dealing with this condition. Is the cyst isolated, can it be treated as such, is its origin always well-defined and does surgical excision provide a permanent cure? PMID:16362357

Fetal ovarian cysts: review of imaging spectrum, differential diagnosis, management, and outcome.  

PubMed

Fetal ovarian cysts are the most common abdominal cysts observed in the female fetus but may be mistaken for genitourinary cysts, gastrointestinal cysts, lymphangiomas, or fetus in fetu. Ultrasonography (US) is the imaging modality of choice for fetal assessment, and magnetic resonance imaging is a useful problem-solving tool when uncertainty remains after careful US evaluation. At US, a fetal ovarian cyst manifests as an anechoic thin-walled cyst superior and parasagittal to the bladder. A daughter cyst may occasionally be observed and is pathognomonic for a cyst of ovarian origin. Fetal ovarian cysts may be simple or complicated and unilateral or bilateral, and they may masquerade as a solid mass when hemorrhage or torsion occurs. Complicated cysts may exhibit multiple septations, fluid-fluid levels, or mobile internal echoes. It is important to differentiate a hemorrhagic ovarian cyst from solid abdominal neoplasms that may be seen in a fetus. Recognition of the pertinent imaging findings will help radiologists distinguish fetal ovarian cysts from other fetal intra-abdominal masses in the differential diagnosis. Malignant ovarian neoplasms are rare in the fetus and neonate and thus are not considered in the differential diagnosis. The current literature on the management and outcome of fetal ovarian cysts is reviewed, with imaging studies presented from the authors' practice. Most fetal ovarian cysts resolve spontaneously; if operative intervention is required, the goal should be ovarian preservation. (©)RSNA, 2015. PMID:25763743

Spinal Extradural Arachnoid Cyst  

PubMed Central

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

Treatment of Ganglion Cysts  

PubMed Central

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

Subcutaneous dermoid cysts were identified in eight wild caribou (Rangifer tarandus) from widely dispersed locations in northern Canada and in one wild caribou from Alaska. The dermoid cysts from Canadian caribou were found among 557 diagnostic specimens that had been detected by hunters and submitted by resource officers and biologists between 1 January 1966 and 15 May 2007. All of the cysts were located in the cervical region, and five of nine cysts were found in the throat area. All of the animals for which the age was known were adult; males and females were equally represented. Dermoid cysts were not diagnosed in any of 1,108 white-tailed deer (Odocoileus virginianus), 293 mule deer (Odocoileus hemionus), 174 elk (Cervus elaphus), or 529 moose (Alces alces) examined during the same period at the Canadian laboratory.

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.

Bronchogenic cyst in the abdomen  

Microsoft Academic Search

A bronchogenic cyst was found in the abdomen, in the retroperitoneum adjacent to the superior pancreatic body. The cyst was unilocular and contained about 100 ml pale yellow mucinous fluid. Microscopic examination revealed a pseudostratified columnar ciliated or cuboidal epithelium, seromucous glands, smooth muscle and cartilage, the distinctive features of bronchogenic cysts. This aberrant location of the cyst is explicable

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

Tarlov Cyst and Infertility  

PubMed Central

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

[Ultrasound-guided transvaginal puncture of ovarian cysts].  

PubMed

Ultrasound-guided transvaginal aspiration of ovarian cysts offers a simple outpatient strategy for immediate pain relief and effective treatment but bears the risk of an iatrogenic spread of malignant cells. This study evaluated the cellular composition of the cyst fluids in a group of 26 sterility patients, in all of whom one or more ovarian cysts had been diagnosed and punctured. None of the patients had complications or evidence of malignant cells on cytological examination after the puncture. Only in one case dyskariotic cells were diagnosed causing an operative exploration that revealed a benign tumour. In 9 patients the ovarian cysts recurred and therefore 2 patients finally underwent an exploratory operation. In our opinion transvaginal ultrasound aspiration of functional cysts is an easy and safe procedure and may be undertaken in sterility patients in the context of specific criteria. PMID:9281256

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 postoperative maxillary cysts after orthognathic surgery: A case report  

PubMed Central

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

Four years later the patient presented with another swelling with similar clinical features. It was located on the midline of the neck at the hyoid bone. Excision of cyst was done and microscopically it showed features of thyroglossal duct cyst (TDC). Two months later a new swelling was noted on the right side of the neck. A complete surgical excision was done and the lesion was diagnosed as a lymphoepithelial cyst. The purpose of this report was to analyze each of the entities that were present in this case; since, the presence of three different cervical cystic lesions in the same patient is uncommon.

Bilateral lateral periodontal cyst.  

PubMed

The bilateral lateral periodontal cyst is a rare nasological entity, which despite clinical and radiological presentation is being diagnosed by histological characteristics. It is asymptomatic in nature and is observed in routine radiography. The aim and objective of this article is to present a rare case of bilateral lateral periodontal cyst in a 14-year-old child. The clinical and radiographical findings, along with its management have been discussed. Enucleation of bilateral cyst without extraction of the adjacent tooth was performed. Lesion samples were sent for histopathological analysis. The histopathological analysis revealed a thin, non keratinised stratified squamous epithelium resembling reduced enamel epithelium. Epithelial plaques were also seen. A clinicopathological correlation incorporating the surgical, radiographical and gold standard histopathological findings was obtained to suggest the final diagnosis of the bilateral lateral periodontal cyst.

Congenital lingual cysts are rare congenital tumors of the oropharynx, which should be suspected when the tongue appears enlarged by a mass. Prenatal diagnosis by ultrasound allows for an optimal management at the time of delivery because the mass can obstruct the airways. Unless the cyst enlarges and hinders feeding or breathing, surgical treatment is indicated only a few months after birth because spontaneous regression can sometimes be observed. PMID:17448749

Acromioclavicular joint cyst formation.  

PubMed

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

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

Incidental Pancreatic Cysts

Hypothesis Widespread use of computed tomography and ultrasound has led to the identification of increasing numbers of patients with asymptomatic cystic lesions of the pancreas. Design Retrospective case series of patients with pancreatic cystic lesions. Setting University-affiliated tertiary care referral center. Patients Two hundred twelve patients with pancreatic cystic lesions seen in our surgical practice during 5 years (April 1997-March 2002). Main Outcome Measures Presence or absence of symptoms, cyst size and location, cytologic or pathologic diagnosis, surgical treatment, and outcome. Results Seventy-eight (36.7%) of 212 patients were asymptomatic. Incidental cysts were smaller (3.3 ± 1.9 vs 4.6 ± 2.7 cm; P<.001) and were found in older patients (65 ± 13 vs 56 ± 15 years; P<.001). Seventy-eight percent of the asymptomatic patients and 87% of those with symptoms underwent surgery, with a single operative death in the entire group (0.5%). Seventeen percent of asymptomatic cysts were serous cystadenomas; 28%, mucinous cystic neoplasms; 27%, intraductal papillary mucinous neoplasms; and 2.5%, ductal adenocarcinomas. The respective numbers for symptomatic cysts were 7%, 16%, 40%, and 9%. Ten percent of asymptomatic patients had a variety of other cystic lesions, and in 12%, no definitive cytologic or pathologic diagnosis was obtained. Overall, 17% of asymptomatic patients had in situ or invasive cancer, and 42% had a premalignant lesion. When evaluated as a function of size, only 1 (3.5%) of 28 asymptomatic cysts smaller than 2 cm had cancer compared with 13 (26%) of 50 cysts larger than 2 cm (P = .04). The proportion of premalignant lesions, however, remained high in both groups (46% and 38%, respectively). Pseudocysts comprised only 3.8% of asymptomatic cysts compared with 19.4% of symptomatic cysts (P = .003). Conclusions Incidental pancreatic cysts are common, occur in older patients, are smaller than symptomatic cysts, and are unlikely to be pseudocysts. More than half of them are either malignant or premalignant lesions and therefore cannot be dismissed. PMID:12686529

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

Follow-up of small, postmenopausal ovarian cysts using vaginal ultrasound and CA-125 antigen.  

PubMed

To determine the natural history of small, simple ovarian cysts in postmenopausal women, 51 postmenopausal patients with small (< 5 cm), smooth, aseptate, hypoechogenic ovarian cysts, without ascites, were followed by vaginal ultrasound examinations every 3 months for an average period of 2.5 years. In 34, CA-125 antigen was measured and found to be within normal limits. None of the cysts showed changes in texture, nor did ascites appear. The CA-125 antigen serum levels remained low. The mean size of the cysts decreased with time. There was no statistically significant correlation between the initial size of the cyst, its tendency to grow or shrink, and the absolute CA-125 serum level. Our findings support the option of a conservative follow-up by repeated ultrasonic and CA-125 antigen examinations of small, simple cysts in postmenopausal women. PMID:8727415

Biochemical markers as predictors of bone remodelling in dental disorders: a narrative description of literature  

PubMed Central

Summary Osteoporosis is a systemic disease in which the skeletal condition is characterized by a decreased mass of normally mineralized bone, due to an augmentation of bone resorption processes. Bone biomarkers serum are used for the diagnosis. On the other hand the main cause of the resorption in the bone jaws are periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. Periodontal diseases can be localized to a single site of the jaws or can affect all the teeth, with a massive bone resorption. The cysts are classified in developmental and inflammatory. They caused a local bone resorption in the jaws. Keratocystic odontogenic tumor produces a large bone resorption for its local aggressive nature. Their diagnosis is clinical and radiological. The aim of our review is to find a correlation between bone biomarkers serum and periodontitis, inflammatory cists, developmental cysts, odontogenetic neoplasms. The RANK/RANKL/OPG system is the most studied not only in osteoporosis but also in the periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms. In the last years osteoimmunology was used to study the periodontal disease progression, because the immunity cells start the bone resorption processes. A lot of studies analyze the biomarkers present in the biofluids, as saliva and gingival crevicular fluid, but not the correlation with serum biomarkers. Future studies must be organized to deepen the correlation between bone biomarkers and bone jaws resorption and to allow diagnosis and prognosis of periodontitis, inflammatory cysts, developmental cysts, odontogenic neoplasms.

Detecting Baker's cyst: venous duplex scanning in ambulatory setting.  

PubMed

Popliteal cyst, also called Baker's cyst, is a popliteal fossa enlargement filled with synovial fluid. Baker's cysts can be symptomatic and cause considerable pathologies such as thrombophlebitis, compartment syndrome and even nerve entrapment. It is the most common nonvascular pathology seen in the popliteal fossa but clinically indistinguishable from deep vein thrombosis. The aim of the present study was to evaluate venous duplex scanning in detecting and distinguishing complicated Baker's cyst and deep vein thrombosis in outpatient setting. Medical records of all patients undergoing venous duplex scanning during 2008 and 2009 to rule out deep vein thrombosis were reviewed. Ten patients having undergone ultrasonography examination were found to have complicated Baker's cyst. Baker's cysts are a rather common condition. When presenting with swollen and painful calf, it is impossible to differentiate it from deep vein thrombosis by simple clinical examination. Venous duplex scanning of lower extremity was found to be a useful imaging modality for detection of Baker's cysts, deep vein thrombosis and associated pathology. PMID:20635584

We report on a case of LPC where successful surgical therapy had initialized osseous restoration. We further discuss the value of histological findings to substantiate a clinical and radiological diagnosis. PMID:24982228

[Surgical and prosthetic treatment of large mandibular cysts].  

PubMed

This paper presents a combined surgical-prosthetic procedure of reconstructing mandibular bone defect in a 53 year old patient, following enucleation of a mandibular cyst (Cystectomy Partsch II). After a thorough diagnostic evaluation, a surgical procedure was planned with the particular attention to the nature of the disease, patient's condition, size and extension of the cyst, tissue loss, and the possibilities of prosthetic management of a mandibular bone defect with partial postresection dental prosthesis. It is of great importance to point to the significance of teamwork of a maxillofacial surgeon and a specialist in prosthodontics. This kind of cooperation provided very effective and less risky soft tissue, as well as bone tissue regeneration (osteogenesis). The patient's recovery was fast, and he could return to his daily activities and work without significant changes regarding quality of life after surgery and prosthetic treatment. PMID:12891734

Baker's cysts in knees with chronic osteoarthritic pain: a clinical, ultrasonographic, radiographic and scintigraphic evaluation.  

PubMed

This study aimed to determine the ultrasonographic prevalence of Baker's cysts in knees with chronic osteoarthritic pain and investigate for cysts correlates and relationships with scintigraphically established synovitis. Consecutive patients with chronic osteoarthritic knee pain underwent clinical examination, X-rays, ultrasonography and early-phase bone scintigraphy. Eighty-nine Baker's cysts were detected in 328 knees with chronic osteoarthritic pain (27%), whereas one cyst was identified among the 54 non-osteoarthritic knees (2%, P<0.001). Baker's cysts were detected in 72/195 (37%) patients with knee osteoarthritis. Abnormal and intense tracer accumulation in early-phase bone scintigraphy were significantly more frequent in osteoarthritic knees with Baker's cysts (97 and 56%, respectively), than in those without (89 and 40%, respectively, P<0.05 for both). Clinical and radiographic variables could not predict the presence of those cysts. Baker's cysts are a common ultrasonographic finding in knees with chronic osteoarthritic pain and are associated with synovial inflammation and its grade. PMID:18584176

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.

Symptomatic sacral perineurial (Tarlov) cysts.  

PubMed

Sacral perineurial (Tarlov) cysts are rare lesions. Over a seven year period 4000 patients underwent surgery for lumbar disk herniation. In three patients neurological symptoms were caused by large sacral perineurial cysts. Methods of choice for diagnosis of Tarlov cysts are lumbosacral magnetic resonance imaging and computerized tomography myelography. The majority of Tarlov cysts are asymptomatic. In case of large (> or = 1.5 cm) and symptomatic perineurial cyst, as in three patients reported in this article, microsurgical treatment was successful. Although rare, perineurial (Tarlov) cysts must be taken into consideration when approaching to patient with low back and radicular pain. Authors review the medical literature, pathological and pathophysiological features and treatment options of sacral perineurial cysts. PMID:20102100

Intradural spinal cysts.  

PubMed

18 cases of benign intradural spinal cyst (9 arachnoidal, 2 neuroepithelial, 7 endodermal) are reported and compared with 94 cases (67 arachnoidal, 7 neuroepithelial, 20 endodermal) obtained from the literature. Arachnoidal intradural cysts (AIC) have no sex preference, occur at around the fourth-fifth decades of life and have characteristic intermittent root symptoms. They prefer the thoracic level and the posterior position. (Myelography images the cystic cavity (diverticular form). Surgical removal is usually easy. Neuroepithelial intradural cysts (NIC) are rare, have a 2:1 predilection for females and occur after the fourth decade. They have a serious clinical course similar to intramedullary or extramedullary tumours. They prefer the conus-cauda and the anterolateral positions. They often give rise to manometric block and to albuminocytological dissociation. There may be substantial adhesions to the cord and roots and the intramedullary variety presents no clear plane of cleavage. Endodermal intradural cysts (EIC) have a 2:1 predilection for males and prefer the second and third decades. They may have an intermittent or serious course with signs of root and cord impairment. They prefer the cervical segment (in the anterior position) and the conus-cauda (in the posterior position). As a rule they present manometric block and albuminocytological dissociation. Their frequent tough adhesions to the roots and cord demand special care during their removal. PMID:6880882

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

Bone hydatid disease  

PubMed Central

Bone hydatid disease lacks a typical clinical appearance and image characteristics on x ray or CT are similar to those of tuberculosis, metastases and giant cell tumour or bone cysts. However, MRI does show distinctive diagnostic features of bone hydatid disease, especially in the spine. Until recently, treatment of osseous hydatid disease has been entirely surgical. Effective chemotherapy using benzimidazoles, particularly mebendazole, albendazole and combination treatments, has now been achieved in experimental studies and clinical practice. However, most of these drugs are still in the experimental stage or are in the early stages of clinical use. PMID:17675547

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

Trace element diffusivities in bone rule out simple diffusive uptake during fossilization but explain in vivo uptake and release  

PubMed Central

Diffusion rates of numerous trace elements in bone at 20 °C were determined using laser-ablation inductively coupled plasma mass spectrometry analysis of experimentally induced diffusion profiles. Diffusivities are about 1 order of magnitude slower than current semiquantitative geochemical views and about 1.5 orders of magnitude faster than indirect radiotracer estimates. Intrabone volume diffusion is too slow and too similar among many elements to explain trace element profiles in young fossils and archeological materials. Diffusivity differences among elements do, however, explain disparate biokinetic washout of Sr vs. Ba and of light vs. heavy rare earth elements (REEs). These results improve the understanding of the physical principles underlying biokinetic models and rates and mechanisms of trace element alteration of phosphatic tissues in paleontological, archeological, and crystal-chemical contexts. Recrystallization and transport limitations in soils explain trace element profiles in young fossils better than intrabone volume diffusion alone and imply that diffusion of REE and other trivalent cations is likely controlled by a common charge–compensating species rather than ionic radii or partition coefficients.

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.

Primary axillary hydatid cyst.  

PubMed

Echinococcosis (hydatid disease) is a zoonosis caused by the larval stage of Echinococcus granulosus (or Taenia echinococcus). The adult form of the parasite lives in the gut of the dog, while the intermediate hosts, where the tapeworm develops to larval stage are cats, cattle, pigs and humans(considered to be accidental intermediate hosts). The parasite has a worldwide distribution, but the endemic areas are Canada and Alaska, Australia, New Zealand, South America and the Mediterranean region. Hydatid cyst can grow many years before the symptoms and clinical signs appear. The liver and the lungs are the most affected organs, but primary location of the hydatid disease in the axilla is extremely rare. In our country we did not find any records of axillary hydatid disease, while the literature contains only 12 cases of axillary location. We present the case of a woman, 60 years old, with a primary axillary location of hydatid cyst, who underwent a total cystectomy. PMID:25149625

Transvaginal aspiration of ovarian cysts: our experience over 121 cases.  

PubMed

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

[Cysts of the kidney in adults. Surgical approach].  

PubMed

90 case records of renal cysts in adults submitted to surgery are studied. A simple pathological classification is proposed. The accompanying signs were, hematuria in 30 p. 100 of cases, but one should always seek another cause; renal colic is present in 22 p. 100 of cases, a palpable tumour in 50 p. 100, on the other hand, infection of the cyst is rare. 35 p. 100 of the cysts were associated with another disease, usually obstructive uropathy, and there were 3 cases of association with carcinoma of the kidney in this series. Pre-operative diagnosis, eliminating carcinoma of the kidney, was ensured by intravenous urography and echotomography which permitted us to restrict the indications for arteriography and aspiration of the cyst. Surgical treatment permits resection of the salient dome of the cyst in the absence of general contra-indications, in order to suppress symptoms due to the cyst and above all, eliminate carcinoma of the kidney. The post-operative period was uneventful and the mortality nil. PMID:64470

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.

Morphological Spectrum of Pilar Cysts  

PubMed Central

Background: Cysts of the skin are one of the commonly excised specimens in the surgical outpatient department. A majority of them being clinically diagnosed as sebaceous cysts, their true nature is only discernible on histopathological examination. Closer examination of the type of keratinization involved will throw light into the exact nature of the cyst. Trichilemmal or Pilar cyst is one such entity, which presents in both a non-neoplastic and neoplastic form. Aims: The present retrospective observational study was undertaken to find out the incidence of these cysts in surgical pathology practice in a rural hospital and to enlist the various morphological forms that these cysts may take. Materials and Methods: The histopathology files were reviewed for a period of 6 years for cases coded as pilar cyst. Results: A total of eight cases (5.75%) were identified, which showed features of trichilemmal differentiation. A single case each of proliferating trichilemmal cyst and malignant proliferating trichilemmal tumors were noted. Most of the cases were seen among females on the scalp. Conclusions: Trichilemmal tumor is an uncommon histopathological entity. Many of these lesions may be mistakenly diagnosed due to lack of recognition of the unique type of keratinization.

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

Multiple infected cerebral hydatid cysts.  

PubMed

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

Popliteal cysts: a current review.  

PubMed

Baker's cyst, or popliteal cyst, is a fluid-filled mass that is a distention of a preexisting bursa in the popliteal fossa, most commonly the gastrocnemio-semimembranosus bursa. This bursa is unique in that it communicates with the knee joint, unlike other periarticular bursae, via an opening in the joint capsule posterior to the medial femoral condyle. Many have theorized that this opening creates a valve-like mechanism in the presence of effusion that contributes to the formation of these cysts in adults. Popliteal cysts rarely manifest alone and are most often found in conjunction with other intra-articular pathologies and inflammatory conditions, such as osteoarthritis, meniscus tears, and rheumatoid arthritis. In children, popliteal cysts are only occasionally associated with these conditions and are more often an incidental finding discovered during a routine physical examination. Popliteal cysts may present as either a chronically persistent or relapsing condition or as an acute and dramatic condition that can occur in the case of cyst rupture presenting as pseudothrombophlebitis. Ultrasound and magnetic resonance imaging have proven to be consistent and accurate in the confirmation of popliteal cysts, with magnetic resonance imaging becoming the modern imaging modality of choice. This review discusses the anatomy and etiology of popliteal cysts, describes the common clinical presentations, reviews the differential diagnoses, and provides guidance for proper diagnostic imaging. It also provides a comparison of current conservative, minimally invasive, and invasive treatment options, along with a discussion of results. Postoperative rehabilitation depends largely on the condition associated with the popliteal cyst. PMID:25102502

It also discusses the investigation and the surgical approach which were carried out with regard to the cyst. Following surgical closure, the teeth were endodontically retreated. It also highlights the fact that mandibular true occlusal radiographs could be misleading with regard to the extent of bone destruction, which can otherwise be confirmed on CT scans. PMID:24086925

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

Contribution to the problem of cyst-producing coccidians.  

PubMed

The problem of life cycles of cyst-producing coccidians, mainly those of the genus Sarcocystis, from carnivorous birds has been discussed. Oocysts of the "sarcocystic" type have been recovered from 9 species of birds of prey and owls from Czechoslovakia. The course of experimental infection in a group of birds consisting of the species Tyto alba, Asio otus, Strix aluco, Buteo buteo has been described. We inoculated these birds with cystic stages of the genus Sarcocystis obtained from white laboratory mice (Mus musculus) infected previously with oocysts from Tyto alba. The nomenclature of heteroxenous coccidians of the genus Sarcocystis has been discussed and suggestions have been made for the use of simple, one-word specific names. A description is given of a new species of the genus Sarcocystis--Sarcocystis dispersa sp. n. Its asexual development and cyst production in Mus musculus (intermediate host), and cyst production in Tyto alba and Asio otus (definitive hosts) have been studied. PMID:416999

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

[Tarlov cyst and symptomatic bladder disfuction].  

PubMed

Tarlov cysts or perineural cyst are lesions of the nerve roots located at the sacral level and uncertain aetiology. Most of these cysts remain asymptomatic with no clinical relevance. The symptomatic cysts are uncommon and the usual symptoms are pain or radiculopathy. We report the case of a 53-year-old woman witha symptomatic cyst (with a history of frequency and urgency syndrom), that disappears after surgery. PMID:19143297

Spinal perineurial and meningeal cysts  

PubMed Central

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. Images PMID:5531903

Ependymal cyst of the midbrain.  

PubMed

We present the case of a 30-year-old man who developed an acute hydrocephalus secondary to an obstruction of the cerebral aqueduct by a midbrain cystic lesion. After a ventriculo-peritoneal shunt was placed to relief symptoms of intracranial hypertension, the patient underwent a neuronavigation-assisted endoscopic fenestration of the cyst. A careful immunohistochemical staining confirmed the diagnosis of an ependymal cyst. An extensive review of the literature has revealed that this is the first report of a periaqueductal ependymal cyst with definite histological diagnosis. This is a rare cause of acute non-communicating hydrocephalus but an important entity in the differential diagnosis. PMID:23254139

Giant adrenal cyst: case study  

PubMed Central

One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61Z–year old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24–h 17–ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

Epidermoid cyst of the spleen.  

PubMed

We report the case of a patient with a palpable mass and abdominal pain in the left upper quadrant. A physical examination revealed tenderness in this region. An ultrasound performed initially showed a large cystic structure. A CT examination revealed a large cyst originating in the spleen with loculations in its upper part and focal calcification in the wall. On MRI, the cystic mass showed high signal on T1-weighted and T2-weighted images. The carbohydrate antigen 19-9 (CA 19-9) was measured at 88 U/ml (standard <37.1 mUI/l). According to the imaging examinations and laboratory tests performed, it was impossible to determine if the splenic cyst was parasitic or non-parasitic. Given the most important risks of complications encountered in parasitic cysts, it was decided to treat this splenic cyst as a parasitic cyst. For this reason, an elective laparoscopic splenectomy with preoperative embolisation of the splenic artery was performed. The histological diagnosis was a primary epidermoid splenic cyst with inner lining epithelial cells. PMID:23667225

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

Multilocular disseminated Tarlov cysts: Importance of imaging and management options  

PubMed Central

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

A huge presacral Tarlov cyst. Case report.  

PubMed

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

Treatment of lateral periodontal cyst with guided tissue regeneration.  

PubMed

Lateral periodontal cyst (LPC), originated from epithelial rests in the periodontal ligament, is a noninflammatory cyst on the lateral surface of the root of a vital tooth. LPC is generally asymptomatic and presents a round or oval uniform lucency with well-defined borders radiographically. In this case report, clinical, histological and radiographical findings and periodontal treatment of 32-year-old female patient, who was referred to Department of Periodontology Clinic of Faculty of Dentistry, Marmara University with a painless hyperplastic lesion on the distobuccal site of the tooth number 12, were presented. The tooth number 12 was vital and a well-defined round radiolucent area with corticated borders was determined radiographically. Preliminary diagnosis was LPC based on clinical and radiographical findings. Mechanical periodontal treatment consisted of oral hygiene instructions, scaling and root planing was applied and flap operation was performed to gain access to the lesion. Following enucleation of the lesion, alveolar bone destruction shaped as a tunnel from labial to palatinal site was observed. The bone cavity was grafted with bovine-derived xenograft, followed by placement of a resorbable collagen membrane. Tissues removed from of the lesion were examined histologically. Hematoxylen-eosin stained sections showed vasculature granulomatous structure underlying squamous epithelium, and destructed bone spaces, all of which were consisted with LPC. Acceptable clinical healing was achieved at 6 months follow-up period. Satisfactory clinical and radiographical outcome can be achieved in the treatment of LPC using regenerative periodontal approach. PMID:25202227

Epithelial cysts of the spleen: a minireview.  

PubMed

Primary splenic epithelial cyst is an unusual event in everyday surgical practice with about 800 cases reported until date in the English literature. Splenic cysts may be parasitic or non-parasitic in origin. Nonparasitic cysts are either primary or secondary. Primary cysts are also called true, congenital, epidermoid or epithelial cysts. Primary splenic cysts account for 10% of all benign non-parasitic splenic cysts and are the most frequent type of splenic cysts in children. Usually, splenic cysts are asymptomatic and can be found incidentally during imaging techniques or on laparotomy. The symptoms are related to the size of cysts. When they assume large sizes, they may present with fullness in the left abdomen, local or referred pain, symptoms due to compression of adjacent structures (like nausea, vomiting, flatulence, diarrhoea) or rarely thrombocytopenia, and occasionally complications such as infection, rupture and/or haemorrhage. The preoperative diagnosis of primary splenic cysts can be ascertained by ultrasonography (USG), computed tomography or magnetic resonance imaging, although the wide use of USG today has led to an increase in the incidence of splenic cysts by 1%. However, careful histopathological evaluation along with immunostaining for presence of epithelial lining is mandatory to arrive at the diagnosis. The treatment has changed drastically from total splenectomy in the past to splenic preservation methods recently. PMID:25320525

Meniscal cysts are one relatively rare disorder of the knee that can cause both pain and mechanical symptoms and are frequently associated with a meniscal tear. In patients with suspected meniscal cysts, systematic differential diagnosis and sound clinical reasoning encourages appropriate integration of the clinical examination with diagnostic imaging. These case reports describe two different presentations of lateral parameniscal cysts where integration of the clinical examination with appropriate imaging allowed the physical therapist to provide a timely and appropriate intervention. In both cases, the diagnostic process is described along with the subsequent interventions that lead to positive outcomes. Level of Evidence: 5 (Case Report) PMID:23772349

A modified intranasal endoscopic excision for nasal vestibular cyst in China.  

PubMed

This study aimed to improve the surgical removal procedure for nasal vestibular cysts. Twenty-three patients with nasal vestibular cysts underwent surgical removal of the cyst via a transoral sublabial approach and another 30 patients via a modified intranasal endoscopic excision method. The 30 patients were treated with local anesthesia and the roof of the cyst, which was firmly attached to the mucous membrane of the anterior floor of the nasal cavity, was removed transnasally with microdebrider. Bleeding of the opening was stopped by electric coagulation without nasal packing. Among the 30 consecutive patients who underwent the modified surgical procedure, all patients were successfully treated. The mean duration of surgery was 5.7 ± 2.6 min. The mean estimated blood loss was 3.5 ± 2.1 ml. All patients were outpatients. The mean hospital stay was 1 h. The mean total cost was 140. The visual analog scale scores of postoperative pain, pressure and nasal obstruction were 1, 0 and 1, respectively. The incidence rate of postoperative lip swelling or numbness was 0 %. Postoperative endoscopic findings revealed that the cyst was replaced by an air-containing sinus with a persistent opening at the anterolateral nasal floor. There was no recurrence during a mean follow-up of 18 months. The modified intranasal endoscopic excision is a simple, less invasive, low-cost and effective surgical procedure for the treatment of nasal vestibular cysts. It might change the pattern of treatment for nasal vestibular cysts in China. PMID:24906844

Bone disease in primary hyperparathyroidism.  

PubMed

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

A 20-year-old primigravida presented in labour with a mass protruding from her vagina during uterine contractions. The mass was a large tense cyst measuring 8 × 8 cm arising from the posterior vaginal wall. The cyst was present since puberty but increased in size during pregnancy. It collapsed following aspiration and uneventful vaginal delivery was conducted. Following delivery, the cyst was excised and vaginal wall repaired. On histopathology the cyst was identified as a Müllerian cyst. The patient recovered and remained asymptomatic on follow-up. PMID:25604504

[Hydatic cyst of the fallopian tube].  

PubMed

Hydatic cyst of the Fallopian tube is an exceptional localization, the diagnosis of which is frequently confirmed preoperatively. A 44-year-old woman was addressed for pelvic mass with fortuitous discovery. The diagnosis preoperatively confirmed by the extemporaneous histological study was hydatic cyst of the Fallopian tube. Salpingectomy was required. The pelvic hydatic cyst, particularly in the Fallopian tube, is a rare complaint. Clinics and biology were very important for diagnosis but only anatomopathology can confirm diagnosis of hydatic cyst. The treatment of Fallopian tube hydatic cyst is surgival and often radical (salpingectomy). PMID:22440619

Clinical experience of symptomatic sacral perineural cyst.  

PubMed

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

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

Laparoscopic treatment of hepatic cysts located in the posterosuperior segments of the liver  

PubMed Central

Purpose Laparoscopy is considered the treatment of choice for hepatic cysts, especially those located in anterolateral segments (AL; segments II, III, IVb, V, and VI) because of the ease of laparoscopic access. Here, we evaluated the feasibility and safety of laparoscopic treatment of hepatic cysts in posterosuperior segments (PS; segments I, IVa, VII, and VIII). Methods We retrospectively analyzed clinical data for 34 patients who underwent laparoscopic treatment of hepatic cysts between September 2004 and December 2012. Patients were divided into two groups depending on whether the main largest cyst was located in AL (n = 20) or PS (n = 14). Laparoscopic cyst unroofing was performed in 29 patients with symptomatic simple cysts. Laparoscopic resection was performed in 5 patients with suspected cystic neoplasms. Results There were no deaths or major complications. The mean operation time was 110 minutes and the mean hospital stay was 4.4 days. The mean cyst size was not significantly different (P = 0.511) but the frequency of multiple cysts was significantly greater in group PS (P = 0.003). The predominant type of resection was unroofing in both groups (P = 0.251). The mean blood loss (P = 0.747), mean hospital stay (P = 0.812), mean operation time (P = 0.669), morbidity rate (P = 0.488), and relapse rate (P = 0.448) were not significantly different. Relapse occurred in one patient who underwent reunroofing 17 months later. The median follow-up is 62 months. Conclusion Laparoscopy is a safe procedure for hepatic cysts located in posterosuperior segments. PMID:24851223

Dentigerous cyst of mandible presenting as sepsis.  

PubMed

Dentigerous cysts are odontogenic cysts that develop by accumulation of fluid between reduced enamel epithelium and a crown of an unerupted tooth. Dentigerous cysts typically are slow growing and incidental findings on radiographic images [1]. These cysts are usually small but when they become large, they will cause a pathologic fracture. Occasionally, they can become painful when infected, which will cause swelling and erythema [1]. We present a rare case of a dentigerous cyst that presented as sepsis. Dentigerous cysts are the most common type of noninflammatory odontogenic cyst [2]. The atypical acute presentation and extent of this patient's soft tissue manifestations resulting in tracheal midline shift and sepsis make this a rare case for presentation. PMID:24985943

Symptomatic Tarlov cyst: report and review.  

PubMed

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

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.

The expression of cytokeratin in keratocystic odontogenic tumor, orthokeratinized odontogenic cyst, dentigerous cyst, radicular cyst and dermoid cyst.  

PubMed

The epithelial lining of odontogenic keratocysts exhibits either parakeratosis or orthokeratosis. In 2005, the WHO classified odontogenic keratocysts with parakeratosis as keratocystic odontogenic tumors (KCOT). Odontogenic keratocysts with orthokeratosis were not classified as odontogenic tumors, but instead referred to as orthokeratinized odontogenic cysts (OOC). To clarify the difference between these two lesions, we investigated their biological characteristics using immunohistochemical studies for cytokeratins (CK) in KCOT and OOC as well as in dentigerous cysts (DC), radicular cysts (RC) and dermoid cysts (DMC). We examined twenty-five cases of KCOT, fifteen cases each of OOC, DC and RC, and ten cases of DMC. We studied the immunohistochemical expression of CK10, 13, 17 and 19. To evaluate the immunohistochemical staining pattern, we divided the epithelial lining of the lesions into three layers (surface layer: su, spinous layer: sp, basal layer: ba). For CK10, most OOC and DMC specimens of su and sp were positive. For CK13 and 19, most KCOT, DC and RC specimens of su and sp were positive. For CK17, most KCOT specimens of su and sp were positive. The percentages of total CK expression of su and sp, and ba of CK19 differed significantly between the lesions (P < 0.001). These results support the hypothesis that OOC originate from not the odontogenic apparatus, but the oral epithelial component. PMID:24092058

New insights about suprapatellar cyst  

PubMed Central

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

Fetal-Neonatal Ovarian Cysts-Their Monitoring and Management: Retrospective Evaluation of 20 Cases and Review of the Literature  

PubMed Central

Objective: Neonatal ovarian cysts (NOC) are usually self-limiting structures. However, large or complex cysts may lead to severe complications. A standard guide to management, treatment and follow-up of NOC is not yet available. The aim of this study was to evaluate retrospectively the records of NOC patients from two medical centers. Methods: A total of 20 newborns with NOC were included in the study. The size and localization of the cyst, the age, the signs and symptoms at presentation, and the possible maternal and fetal-neonatal etiologic factors were recorded. Follow-up procedures and treatment modalities were evaluated. Results: The mean age at diagnosis was 34 gestational weeks. The cysts (mean size 53±15 mm) were predominantly in the right ovary (75%) and were evaluated as large cysts in 16 (80%) of the patients. In 5 of the patients with large cysts and in 1 of the 4 patients with small cysts, the cysts were evaluated as complex cysts. Torsion of the ovary was detected in five (25%) cases and these cases were treated surgically. Patients with simple cysts were closely followed by ultrasonography until the cysts disappeared. Conclusion: To date, there is no precise guide for the monitoring and treatment of NOCs. Surgical treatment should always be performed in a way to protect the ovaries and to ensure future fertility. In our NOC series, it has been possible to apply a non-invasive follow-up program and minimally invasive surgical procedures. Conflict of interest:None declared. PMID:21274333

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.

Endocortical bone loss in osteoporosis: the role of bone surface availability  

E-print Network

Age-related bone loss and postmenopausal osteoporosis are disorders of bone remodelling, in which less bone is reformed than resorbed. Yet, this dysregulation of bone remodelling does not occur equally in all bone regions. Loss of bone is more pronounced near the endocortex, leading to cortical wall thinning and medullary cavity expansion, a process sometimes referred to as "trabecularisation" or "cancellisation". Cortical wall thinning is of primary concern in osteoporosis due to the strong reduction in bone mechanical properties that it is associated with. In this paper, we examine the possibility that the nonuniformity of microscopic bone surface availability could explain the nonuniformity of bone loss in osteoporosis. We use a simple computational model of bone remodelling, in which microscopic bone surface availability influences bone turnover rate, to simulate the evolution of the bone volume fraction profile across the midshaft of a long bone. We find that bone loss is accelerated near the endocortica...

Electron microscopy of Giardia lamblia cysts.  

PubMed Central

The flagellated protozoan Giardia lamblia is a recognized public health problem. Intestinal infection can result in acute or chronic diarrhea with associated symptoms in humans. As part of a study to evaluate removal of G. lamblia cysts from drinking water by the processes of coagulation and dual-media filtration, we developed a methodology by using 5.0-microns-porosity membrane filters to evaluate the filtration efficiency. We found that recovery rates of G. lamblia cysts by membrane filtration varied depending upon the type and diameter of the membrane filter. Examination of membrane-filtered samples by scanning electron microscopy revealed flexible and flattened G. lamblia cysts on the filter surface. This feature may be responsible for the low recovery rates with certain filters and, moreover, may have implications in water treatment technology. Formation of the cyst wall is discussed. Electron micrographs of cysts apparently undergoing binary fission and cysts exhibiting a possible bacterial association are shown. Images PMID:7425627

Allantoic cyst – an unusual umbilical cord swelling  

PubMed Central

We report a baby with an unusual umbilical cord swelling. On the antenatal scans, a cystic area within the umbilical cord near its insertion onto the abdominal wall was detected. Postnatally an unusually thick umbilical cord with a yellow fluid filled cyst at the base was noted. The fluid from the cyst was confirmed as urine and ultrasound confirmed patent urachus. The baby underwent a cystoscopy and excision of patent urachus with associated allantoic cyst. Allantoic cyst is a rare swelling formed at the base of umbilicus associated with a patent urachus which results from an allantoic remnant. Paediatricians need to be aware about this condition as investigation is required to differentiate allantois cysts from umbilical pseudocysts. A patent urachus with allantoic cyst requires surgical excision. PMID:24950576

Giant radicular cyst of the maxilla.  

PubMed

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

Two Rare Presentations of Epidermal Cyst  

PubMed Central

Epidermal cysts are very rare. It is more common in males than in females and the most common site of presentation are the hairy sites. We came across two rare cases of epidermal cysts. 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.

Treatment of an Extensive Maxillary Cyst Using Nasal Airway and Balloon Catheter Devices  

PubMed Central

Introduction. Large maxillary cysts occasionally expand into the maxilla and erode the maxillary sinus and nasal cavity. The Caldwell-Luc procedure is the recommended treatment for large maxillary sinus cysts. However, it is hard to preserve the nasal space in the case of large maxillary sinus cysts that penetrate into the nasal cavity. Methods. A 22-year-old man who had large maxillary sinus cysts was referred to our department for a surgical treatment. After removing the cyst from the maxillary sinus using the Caldwell-Luc procedure, we used nasal airway and balloon catheter devices to preserve the space of the inferior nasal meatus and maxillary sinus. These devices were removed 10 days postoperatively. Insertion and removal of both devices were simple and painless. Findings. The nasal airway and balloon catheter devices were useful for performing maxillary sinus surgery to remove large cysts. Our method was satisfactorily safe and was an effective minimally invasive treatment that preserved the space of the inferior nasal meatus and maxillary sinus. PMID:24804124

Surgical treatment of sacral perineural cyst--case report.  

PubMed

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

Surgical Management of Pulmonary Hydatid Cysts  

PubMed Central

Giant hydatid cysts of the lung (diameter, ?10 cm) are considered more difficult to treat surgically than are smaller cysts. We reviewed our experience with giant pulmonary hydatid cysts, focusing on clinical symptoms, cystic location, extent of surgery, and postoperative complications, according to age, long-term results, and comparison with non-giant cysts. From January 1988 to January 2008, 537 patients underwent surgery for pulmonary hydatid cysts. We separated patients into 2 groups: patients who had cysts <10 cm (group A) and those who had giant cysts (group B). Group B comprised 75 patients (14%). Giant cysts were more common in younger patients (mean age, 30 vs 32 yr; P=0.014). The most frequent complaints were cough, chest pain, and dyspnea. Patients with giant cysts were more often symptomatic at presentation (96% vs 88%; P=0.04). In both groups, lower-lobe locations predominated. Parenchyma-saving operations were almost uniformly performed for each group; however, a higher percentage of patients in group B required anatomic resection (4% vs 1%; P=0.038). Fifty-seven patients (10%) also underwent resection of concomitant liver cysts. Cystic rupture occurred more frequently in group B than in group A (27% vs 15%; P=0.01). There were no deaths in either group, nor were there significant differences in morbidity between groups. In summary, giant hydatid cysts of the lung occurred more often in younger patients and were more often symptomatic at presentation. Regardless of size, the cysts could usually be surgically treated without lung resection, and size did not appear to influence short-term perioperative outcomes. PMID:20844615

Tarlov cysts: a report of two cases.  

PubMed

Perineural cysts are common and usually detected incidentally during magnetic resonance imaging of the lumbosacral spine. Treatment is indicated only when the cyst is symptomatic. We report one such patients presented with cauda equina syndrome and another with low back pain with claudication. They underwent excision and duraplasty; both motor and sensory fibres were carefully separated from the cyst wall using a nerve root retractor and penfield. There was no nerve root damage or neural deficit. Symptoms were relieved postoperatively. PMID:22535818

Radicular cyst masquerading as a multilocular radiolucency.  

PubMed

Radicular cysts are the most common cystic lesions of the jaw. Most of these lesions involve the apex of the offending tooth and appear as well-defined periapical radiolucencies. This case presents an unusually large multilocular radicular cyst crossing the midline and involving almost the entire body of the mandible. The clinical and radiographic appearance mimicked an aggressive cyst or benign tumor. The lesion was surgically excised, and the teeth were endodontically treated without any postoperative complications. PMID:23444164

[Bronchogenic cysts in the carina].  

PubMed

Between 1977 and 1990, 11 children with carinal bronchogenic cysts were operated in our institution: 8 girls and 3 boys, ranging in age from 1 month to 5 years. All were symptomatic (acute respiratory distress and recurrent bronchiolitis). Chest X-ray showed an unilateral over distension in 10/11 cases. Barium oesophagogram showed a compression in 6/10 cases. Bronchoscopy noticed an extrinsic compression in 10/11 cases and a tracheal and/or bronchial diskinesia in 5/11 cases. The computed tomography showed a low density mass in 4/4 cases. 9 cysts were left-sided and 2 right-sided. Both children underwent a second surgery for a second cyst. 2 pneumonectomies for complete parenchyma destruction were realised. 1 left pulmonary hypoplasia was noticed. A tracheal and/or bronchial diskinesia in post-operative was noticed in 5/6 cases. The clinical and functional respiratory following was good in 10/11 cases. An early surgery treatment is necessary before definitive sequelae. PMID:1439091

A simple technique for reconstruction of medial patellofemoral ligament with bone-fascia tunnel fixation at the medial margin of the patella: a 6-year-minimum follow-up study  

PubMed Central

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

Nasoalveolar cyst: an enigma for the dentist.  

PubMed

A nasoalveolar cyst is a rare, non-odontogenic soft tissue cyst encountered in the anterior maxillary labial sulcus as an asymptomatic soft tissue swelling. Often, patients with these cysts report them to the dental clinic where they are mistaken for odontogenic lesions by the dental surgeon, especially if concomitant dental problems are present. They cannot be detected by routine conventional dental radiography as they are peripheral, lying within the mucosa thereby posing a diagnostic challenge. We document a case of a 47-year-old woman with a nasoalveolar cyst. PMID:25566935

Multiple Organ Involvement with Hydatid Cysts  

PubMed Central

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

Laparoscopic management of huge ovarian cysts.  

PubMed

Objectives. Huge ovarian cysts are conventionally managed by laparotomy. We present 5 cases with huge ovarian cysts managed by laparoscopic endoscopic surgery without any complications. Materials and Methods. We describe five patients who had their surgeries conducted in a tertiary care center in Riyadh, Saudi Arabia (King Fahad Medical City). Results. Patients age ranged between 19 and 69 years. Tumor markers were normal for all patients. The maximum diameter of all cysts ranged between 18 and 42?cm as measured by ultrasound. The cysts were unilocular; in some patients, there were fine septations. All patients had open-entry laparoscopy. After evaluation of the cyst capsule, the cysts were drained under laparoscopic guidance, 1-12 liters were drained from the cysts (mean 5.2?L), and then laparoscopic oophorectomy was done. The final histopathology reports confirmed benign serous cystadenoma in four patients and one patient had a benign mucinous cystadenoma. There was minimal blood loss during surgeries and with no complications for all patients. Conclusion. There is still no consensus for the size limitation of ovarian cysts decided to be a contraindication for laparoscopic management. With advancing techniques, proper patients selection, and availability of experts in gynecologic endoscopy, it is possible to remove giant cyst by laparoscopy. PMID:23766763

Evolution of the Surgical Management of Neonatal Ovarian Cysts: Laparoscopic-Assisted Transumbilical Extracorporeal Ovarian Cystectomy (LATEC)*  

PubMed Central

Abstract Purpose Since its first detailed description in 1995, the laparoscopic management of neonatal ovarian cysts has typically required multiple incisions, specialized equipment, and advanced laparoscopic skills. After some initial frustration with neonatal laparoscopy, we developed a simplified single-incision laparoscopic-assisted transumbilical extracorporeal cystectomy (LATEC). This paper reviews our experience with this technique and compares outcomes to those of our other surgically managed neonatal ovarian cyst patients. Materials and Methods A retrospective record review of 20 patients treated surgically between 1992 and 2006. Student's t-tests were used for comparisons (P < 0.05 was significant). Results Means were: age, 11 days; weight, 3.7 kg; and cyst diameter, 5.0 cm. Nineteen patients were diagnosed prenatally, at the mean gestational age of 33 weeks. Twelve of 20 (60%) had torsed cysts (1 bilateral). Three of 13 torsed cysts (23%) were less than 4 cm diameter (range, 2.9–3.5). Laparotomies were transverse lower abdominal incisions. Laparoscopic operations used 2 (3 patients) or 3 incisions (2 patients). LATEC involved transumbilical laparoscopy, complete cyst aspiration, and then cyst evisceration through the umbilicus for either ovarian cystectomy (simple cysts) or salpingo-oophorectomy (torsed cysts). Laparoscopic patients had similar time to feeds, length of stay, and postoperative narcotic requirements, when compared to laparotomy patients (P = nonsignificant). LATEC patients had shorter surgical times, more rapid advancement to full enteral feedings, shorter length of hospital stay, and equal ovarian preservation, when compared to laparoscopy. Cosmetic results with LATEC were outstanding. Conclusions Both laparoscopic and “open” approaches have acceptable perioperative morbidity and rapid recovery. LATEC is a relatively simple procedure, which combines laparoscopy and traditional extracorporeal surgery, and may be successfully performed by experienced pediatric surgeons and with a single incision.

Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed. PMID:19096672

A simple spectrophotometric method for the determination of phosphate in soil, detergents, water, bone and food samples through the formation of phosphomolybdate complex followed by its reduction with thiourea  

NASA Astrophysics Data System (ADS)

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.

Proteomic Analyses of Pancreatic Cyst Fluids  

PubMed Central

Objectives There are currently no diagnostic indicators that are consistently reliable, obtainable, and conclusive for diagnosing and risk-stratifying pancreatic cysts. Proteomic analyses were performed to explore pancreatic cyst fluids to yield effective diagnostic biomarkers. Methods We have prospectively recruited 20 research participants and prepared their pancreatic cyst fluids specifically for proteomic analyses. Proteomic approaches applied were: 1) MALDI-TOF (matrix-assisted laser-desorption-ionization time-of-flight) mass spectrometry peptidomics with LC/MS/MS (HPLC-tandem mass spectrometry) protein identification. 2) 2D gel electrophoresis. 3) GeLC/MS/MS (tryptic digestion of proteins fractionated by SDS-PAGE and identified by LC/MS/MS). Results Sequencing of over 350 free peptides showed that exopeptidase activities rendered peptidomics of cyst fluids unreliable; Protein nicking by proteases in the cyst fluids produced hundreds of protein spots from the major proteins, making 2D gel proteomics unmanageable; GeLC/MS/MS revealed a panel of potential biomarker proteins that correlated with CEA (carcinoembryonic antigen). Conclusions Two homologs of amylase, solubilized molecules of four mucins, four solubilized CEACAMs (CEA-related cell adhesion molecules), and four S100 homologs, may be candidate biomarkers to facilitate future pancreatic cyst diagnosis and risk-stratification. This approach required less than 40 microliters of cyst fluid per sample, offering the possibility to analyze cysts smaller than 1 cm diameter. PMID:19136908

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. PMID:25685785

Choledochal cysts : a review of literature.  

PubMed

Choledochal cysts are cystic dilation of extrahepatic duct, intrahepatic duct, or both that may result in significant morbidity and mortality, unless identified early and managed appropriately. The incidence is common in Asian population compared with western counterpart with more than two third of the cases in Asia being reported from Japan. The traditional anatomic classification system is under debate with more focus on etiopathogenesis and other aspects of choledochal cysts. Even though categorized under the same roof, choledochal cysts vary with respect to their natural course, complications, and management. In this review, with the available literature on choledochal cysts, we discuss different views about the etiopathogenesis along with the natural course, complications, diagnosis, and surgical approach for choledochal cysts, which also explains why the traditional classification is questioned by some authors.

Groove pancreatitis associated with true pancreatic cyst.  

PubMed

We report a case of groove pancreatitis (GP) associated with a true pancreatic cyst. An 81-year-old man who had suffered epigastric pain for 4 months was referred to Saisekai Kure Hospital. Computed tomography and endoscopic retrograde pancreatography showed a cystic lesion in the groove area of the pancreas. Serum amylase elevation and imaging findings suggested GP due to the cyst. Six weeks of medical treatment did not improve the clinical symptoms. Therefore, pancreatoduodenectomy was performed. Histologic examination revealed a true cyst with intraluminal necrosis, which produced a protein plug that obstructed the Santorini duct. The parenchyma surrounding the groove area showed marked fibrosis and inflammatory cell infiltration. GP due to true pancreatic cyst was diagnosed. Although GP is usually caused by overconsumption of alcohol, which leads to changes in the pancreatic juice and the ultimate blockage of pancreatic outflow, the histologic features in our patient suggest that true pancreatic cyst stands as a secondary cause of GP.

Simple conditioning with monospecific CD4+CD25+ regulatory T cells for bone marrow engraftment and tolerance to multiple gene products.  

PubMed

A major impediment to gene replacement therapy is immune elimination of genetically modified cells. In principle, this can be dealt with by inducing a strong, specific, and enduring tolerance through engraftment of transgene-modified autologous bone marrow (BM). Because usual myeloablation and/or immunosuppression are risk factors in most pathologies, we assessed the potential of monospecific CD4(+)CD25(+) regulatory T cells (Tregs) to engraft minor-mismatched BM without preconditioning. We found that as few as 5 x 10(4) Tregs directed to the male DBY protein promote the engraftment of foreign male BM into sex-mismatched female hosts, establishing sustained chimerism in all hematopoeitic compartments. We achieved concomitantly strong tolerance to all foreign antigens expressed in the BM, likely occurring through induction of anergy and/or deletion of antidonor T cells. Chimerism was obtained in thymectomized mice too, underlining the major role of peripheral tolerance mechanisms in our system. This allowed us to engraft gene-modified tissues while preserving full immunocompetence to third-party antigens. Our results demonstrate that very few donor-specific Tregs are effective as the sole conditioning to induce mixed molecular chimerism and long-term tolerance to multiple foreign antigens.

Management of urinary calculous disease in patients with renal cysts: review of 12 years of experience in 18 patients.  

PubMed

During the last 12 years 18 patients with urinary calculi were found to have associated cystic renal disease. We herein describe the difficulties in diagnosing and in treating this group, which included patients with simple single renal cysts, multiple cysts of 1 or both kidneys and polycystic renal disease. Renal calculi may be caused by or perpetuated by renal cystic disease. After spontaneous passage or surgical removal renal calculi may recur as long as renal cysts continue to cause urinary stasis owing to obstruction and distortion of the renal calices. Superimposed renal infection may cause further difficulties in diagnosis and treatment. The timely removal of calculi and the relief of obstruction caused by the cysts and stones are emphasized. We further recommend the judicious use of antibiotics, correction of electrolyte disturbances and prolonged followup in an attempt to prevent future calculous disease. PMID:7206042

Multiple fluid-filled bone metastases.  

PubMed

Bone metastases are usually seen on imaging studies as lytic lesions and less often as sclerotic or mixed lesions. We report an exceedingly unusual case of breast cancer identified after magnetic resonance imaging showed bone metastases with fluid-fluid levels in the spine and sacrum. Bone images containing fluid-fluid levels are usually solitary abnormalities produced by aneurismal bone cysts. The fluid-fluid level is due to bleeding within the tumor followed by layering of the blood components based on density differences. Only two other cases of bone metastases with multiple fluid-fluid levels have been reported. Although fluid-fluid levels are exceedingly rare, clinicians should be aware that they might indicate a malignancy, particularly when they are multiple. PMID:20194045

Clinical considerations, management and treatment of fever of unknown origin caused by urachal cyst: a case report  

PubMed Central

Introduction Urachal cysts are rare congenital anomalies that often prompt referral to the paediatric general surgeon because of their associated complications such as infection, abdominal pain and the young age at presentation. In this report we describe a rare case of fever of unknown origin caused by an urachal cyst which was successfully treated with incision and drainage only. Since the first description of urachal anomalies by Cabriolus in 1550, few cases have been reported and, until now, only one case of infected urachal cyst presenting as fever of unknown origin has been described in the literature. Moreover, the spontaneous resolution of an urachal cyst without excision is extremely rare. Case presentation We report our experience in the management and treatment of an infected urachal cyst that occurred in a 12-year-old Caucasian girl who presented to our Department of Paediatric Surgery with a 30-day history of evening fever. The urachal cyst was treated only with incision and drainage through a minimally invasive laparoscopic approach. Conclusions The incision and drainage of an infected urachal cyst is a simple and safe procedure. It assures a complete recovery and avoids potential surgical complications related to the total excision of the urachal cyst. This report may provide important clues regarding the management of this rare anomaly and we emphasise the importance for paediatricians, who should consider the possibility that a fever of unknown origin can be caused by an urachal cyst, and for surgeons and urologists, because it suggests that conservative treatment of this rare anomaly should be considered when possible.

Isolated Retroperitoneal Hydatid Cyst Invading Splenic Hilum  

PubMed Central

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

Lumbosacral arachnoid cyst with tethered cord: A rare case report  

PubMed Central

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

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.

Hydatid Cyst Confined to the Papillary Muscle  

PubMed Central

Cardiac involvement of hydatid cysts is rare. Hydatidosis of the valvular apparatus can be treated successfully by the careful application of valvular surgical procedures. To the best of our knowledge, cardiac hydatidosis confined to the anterolateral papillary muscle has not been reported. Herein, we present a case involving a hydatid cyst that was located in a cardiac papillary muscle and that caused mitral regurgitation in a 37-year-old woman. The cyst was removed by papillary muscle incision, and the mitral valve was repaired. The patient experienced an uneventful recovery. PMID:20069089

Biocontrol: fungal parasites of female cyst nematodes.  

PubMed

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. The potential of these nematophagous fungi as biocontrol agents is discussed. PMID:19300700

The authors report a rare case of epidermoid cyst with interhemispheric growth closely connected to the anterior portion of the corpus callosum. Although extremely sensitive in determining the site, dimensions and relations of the lesion, NMR does not allow the nature of this pathology to be diagnosed owing to the lack of signal specificity. CT, using the measurement of Hounsfield units, allows a differential diagnosis of epidermoid cysts and arachnoid cysts and lipomas to be made in almost all cases. Treatment is surgical and the complete excision of the capsule avoids recidivation. PMID:8622812

Anaphylactic Shock During Pulmonary Hydatid Cyst Surgery  

PubMed Central

Introduction: Hydatid cyst is a parasitic disease caused by a tapeworm Echinococcusgranulosus. Humans are accidental hosts and infected after digestion of foods contaminated to fecal matter of definite hosts. The most affected organs are liver and lungs. Rupture of cyst (spontaneous rupture or rupture due to trauma or surgery) can cause anaphylactic reactions. Even considered as a rare event during anesthesia, it can be life threatening with the manifestations of severe hypotension and circulatory shock. Thus, immediate and proper treatment is necessary . Case Presentation: We report a case of anaphylactic shock during surgery of pulmonary Hydatid cyst in a 42 year old woman and its management. Conclusions: During the surgery of hydatid cyst, any hemodynamic instability should raise the suspension of anaphylaxis and early resuscitation should be instituted. PMID:25237636

A rare case of a posttraumatic extensive ganglion cyst of the anterolateral thigh with connection to the knee joint is presented. A 54-year-old man presented a palpable mass in the anterolateral region of his right thigh with a 15 months existing sense of fullness and tightness. He had an accident with his bicycle 21 months ago. Magnetic resonance imaging (MRI) was performed showing a cyst inside the quadriceps femoris muscle between vastus lateralis and intermedius with connection to recessus suprapatellaris and knee joint. In addition MRI detected a traumatic lesion in the quadriceps femoris tendon in the near of the knee joint. The ganglion cyst was 18 cm long and was excised completely. Intraoperatively, the knee joint connection was confirmed and excised as well. The ganglion cyst was filled with a gelatinous and viscous fluid. PMID:24765322

Aggressive dentigerous cyst with ectopic central incisor.  

PubMed

Dentigerous cysts form from accumulation of fluid between reduced enamel epithelium and the crown of an unerupted tooth. They cause several difficulties such as swelling, non-eruption of the involved teeth, and displacement of adjacent teeth, and thus require early detection and prompt treatment. Treatment ranges from marsupialisation to enucleation. Enucleation is rarely used in children compared with marsupialisation. This paper discusses successful use of enucleation for treating a dentigerous cyst and explains the need for such a radical procedure. PMID:24913076

Perineural cyst presenting like cubital tunnel syndrome.  

PubMed

Perineural cysts are believed to be asymptomatic; however, they rarely cause symptoms related to nerve root compression. Cervical symptomatic perineural cysts are in fact exceedingly rare. There are no reported cervical perineural cysts in the literature that present like cubital tunnel syndrome. A patient with motor weakness of the abductor and adductor muscles of the fingers of the left hand and hypoesthesia in the hypothenar region of the left hand presented at our clinic. A neurological examination, and neuroradiological and electrophysiological evaluations supported the finding that the patient's clinical condition was caused by a perineural cyst located around the C8 neural root. The neurological symptoms of the patient markedly improved after medical treatment. We reported the first cervical perineural cyst as presenting like cubital tunnel syndrome patient in the literature. The visualization of perineural cyst may need extra magnetic resonance imaging (MRI) sections in order to view the nerve root through the neural foramen or extraforaminal area. These lesions are benign, and the appropriate treatment is curative. PMID:21574015

Bone transplantation and tissue engineering, part III: allografts, bone grafting and bone banking in the twentieth century.  

PubMed

During the 20th century, allograft implantation waned in popularity as a clinical activity. Reports appeared in the literature describing several small series of patients in whom bone was obtained from amputation specimens or recently deceased individuals. The concept of bone banking became a reality during and after World War II when the National Naval Tissue Bank was established in Bethesda and a number of small banks sprang up in hospitals throughout the world. Small fragments, either of cortical or medullary bone, from these banks were used heterotopically to augment spinal fusions, to implant into cyst cavities, or to serve as a scaffolding for repair of non- or delayed union of fractures of the long bones.

The purpose of this paper is to point out the value of CBCT exam in pre and postoperative diagnosis assessment of inflammatory radicular cysts together with full appreciation of local integration of alloplastic graft materials used to repair the osseous defects. There were statistically retrospective evaluated the pre and postoperative results of CBCT and x-ray examinations of 34 patients with inflammatory radicular cysts clinically, biologically and histopathologically assessed at Oral and Maxilo-Facial Surgery Clinic from Timisoara. In all cases we proceeded to surgical radicular cysts removement, extraction of the associated non-vital tooth together with alloplastic graft materials repairement of the osseous defects. The CBCT preoperative scans clearly showed the extent, the morphological characteristics and the topoanatomic reports, in all 34 cases of inflammatory radicular cysts together with regional endodontic status. The CBCT postoperative scans revealed the very local integration of alloplastic graft materials used to repair the osseous defects and, in some cases, the dental rehabilitation by metallic implants. CBCT scan is the imaging method of choice in pre and postoperative diagnosis assessment of inflammatory radicular cysts together with alloplastic graft materials repairement of the osseous defects and dental rehabilitation by metallic implants, due to high specific abilities in bone tissue 3D evaluation.

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.

[Bone Reconstruction of Autolyzed Antigen-free Allogenic /AAA/ Bone in Children and Adolescents with Benign Bone Tumours.].  

PubMed

The authors describe in detail the preparation of six batches of human AAA/autolyzed antigen-free allogenic bone/ prepared in 1985 to 1988. This bone was administered to a total of 48 children and adolescents aged 6 to 19 years. It was used to fill cavities after metaphyseal connective tissue bone defects /31 x/, solitary bone cysts /10 x/, enchondromas /5 x/ and fibrous dysplasia /2 x/. The observation period was 2 years and 2 months to 5 years and 9 months. The mean volume of the cavities was 21 ml. In all patients the X-ray pictures were evaluated in a chronological sequence and changes on the host s bones in the cavity and the inserted AAA bones were described, and finally also changes of the entire bone complex with incorporated AAA implants. The results were arranged in tables. On the host's bones a periosteal reaction was observed in the area surrounding the focus, the entire cavity was covered with a soft shadow, there was sclerosis of the margins and bottom of the bone bed and gradual diminution of the bone defect from the sides and bottom of the bed. On the AAA bones the following observations were of interest: the connection of AAA bone with the surrounding newly formed bone, less clearly defined outlines of the AAA bone, loss of identity of the AAA bone. Sclerosis or elimination of the AAA bone were not observed. In three patients with batch 5 a "halo" effect was observed. On the entire complex with incorporated AAA bones the following were investigated: sclerosis of the entire portion of the bone, then regression and diminution of sclerosis, differentiation of the corticalis and medullary cavity and formation of a normal bone structure without signs of previous treatment. Preparation of six different batches of AA bone revealed that: 1.The spongious parts are more readily and more rapidly incorporated than the cortical part which is only partly demineralized. 2.Gelatinization with LiCI had a favourable effect on the incorporation of thus prepared implants. X-ray investigation revealed that the course of incorporation and reconstruction of these bones has the following specific features: 1.Reconstruction begins as a rule by the periosteal reaction of the host and its shift above the gap has a favourable effect on healing of the defect. 2.Two months after operation the cavity is covered by a soft shadow when the newly formed vessels and mesenchymal cells of the host infiltrate into the focus. 3.Activation of the bed is manifested by its greater density, sclerotization and by gradual diminution of the volume of the cavity. The greater density is not necessarily associated with diminution of the size of the cavity. 4.Bone implants are connected to the newly formed bone without passing through the stage of densi fication and sclerotization. The newly formed bone infiltrates them, absorbs and replaces the bone proper without signs of the previous stage of scle rosis, as observed in patients with frozen allogenic bones. 5.After incorporation of AAA implants further bone reconstruction takes place, as known from the healing of fractures or bone gaps.

Percutaneous Fibrin Gel Injection under C-Arm Fluoroscopy Guidance: A New Minimally Invasive Choice for Symptomatic Sacral Perineural Cysts  

PubMed Central

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

Bone Crusher  

NSDL National Science Digital Library

Students use a tension-compression machine (or an alternative bone-breaking setup) to see how different bones fracture differently and with different amounts of force, depending on their body locations. Teams determine bone mass and volume, calculate bone density, and predict fracture force. Then they each test a small animal bone (chicken, turkey, cat) to failure, examining the break to analyze the fracture type. Groups conduct research about biomedical challenges, materials and repair methods, and design repair treatment plans specific to their bones and fracture types, presenting their design recommendations to the class.

Klestadt's Cyst with Radiographic Contrast Medium: A Case Report.  

PubMed

Klestadt's cyst is commonly known as Nasolabial cyst, is a rare non-odontogenic, soft-tissue, developmental cyst. It accounts for around 0.7% of cysts of the jaws and 2.5% of the nonodontogenic cysts. Following its first description in 1882 by Zukuerkandl, very few cases have been documented in the literature. The cyst usually occurs in the nasolabial region, as a slowly enlarging asymptomatic swelling. As it is a soft tissue cyst, it doesn't show any radiographic changes. Thus contrast medium can be used to visualize the definite extensions. This paper documents a case of nasolabial cyst which was successfully treated in which a radiographic contrast medium was used in order to define the actual extensions of the lesion. PMID:25478470

Ependymal cyst of the spinal cord: case report  

PubMed Central

A subarachnoid ependymal cyst of the spinal cord is rarely reported. A 44 year old man with a cyst compressing the lower spinal cord and conus medullaris is described. Excellent functional recovery followed excision of the lesion. The cells lining the cyst were histologically indistinguishable from normal ependymal cells, but, unlike the normal ependymal cells which are related to subependymal glial tissue, the cells lining the cyst abutted directly on the connective tissue forming the cyst wall. This is in contrast with ependymal lined cysts occurring within the conus medullaris, and intradural teratomatous cysts which consistently contain intracytoplasmic mucinous material. It is postulated that an ependymal cyst could result from isolation of ependymal cells from either the roof or floor plates during embryogenesis of the neural tube. Images PMID:5122382

Dentigerous Cyst associated with Horizontally Impacted Mandibular Second Premolar  

PubMed Central

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

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

Duplication cysts: Diagnosis, management, and the role of endoscopic ultrasound  

PubMed Central

Gastrointestinal tract duplication cysts are rare congenital gastrointestinal malformation in young patients and adults. They consist of foregut duplication cysts, small bowel duplication cysts, and large bowel duplication cysts. Endoscopic ultrasound (EUS) has been widely used as a modality for the evaluation and diagnosis of duplication cysts. EUS is the diagnostic tool of choice to investigate duplication cysts since it can distinguish between solid and cystic lesions. The question of whether or not to perform EUS-fine needle aspiration (EUS-FNA) on a lesion suspected of being a duplication cyst is controversial as these lesions can become infected with significant consequences, although EUS-FNA is often required to obtain a definitive diagnosis and to rule out more ominous lesions. This manuscript will review the literature on duplication cysts throughout the body and will also focus on the role of EUS and FNA with regards to these lesions. PMID:25184121

Dermoid cyst in a domestic shorthair cat  

PubMed Central

A 5-year-old neutered male domestic shorthair cat was presented for examination of a subcutaneous mass in his tail. The mass was firm, non-painful, oval, and approximately 2.5 × 3.5 cm. Surgical exploration revealed a well-circumscribed, encapsulated mass. The mass was removed and sectioned for histopathological examination. In gross section, it was filled with numerous dark hairs. Histologically the mass was consisted of haired skin with dermal cystic structures lined by stratified squamous epithelium. The cyst lumen contained squamous debris and filled with keratinous material. Numerous hair shafts were extended from the wall of the cyst. The sebaceous and apocrine gland adnexal structures were also observed which confirmed the diagnosis of dermoid cyst. No tumor recurrence was observed after surgery in fallowing checkups. Cutaneous or subcutaneous cysts of all types are considered rare in cats and to our knowledge this is the third reported case of cutaneous dermoid cyst of cats in veterinary literature which is different from the other cases because it occurred in dorsal midline in tail area whereas others occurred in flank area.

Synovial cyst mimicking an intraspinal sacral mass.  

PubMed

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

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.

Immunocytochemical expression of growth factors by odontogenic jaw cysts.  

PubMed Central

AIM: To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS: Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 radicular cysts) using a streptavidin-biotin peroxidase technique with monoclonal antibodies directed against TGF alpha (clone 213-4.4) and TGF beta (clone TB21) and a polyclonal antibody directed against EGF (Z-12). RESULTS: The epithelial linings of all cysts showed reactivity for TGF alpha which was mainly localised to basal and suprabasal layers. Odontogenic keratocyst linings expressed higher levels of TGF alpha than those of dentigerous and radicular cysts, with 89% (24/27) of odontogenic keratocysts exhibiting a strong positive reaction compared with 50% (five of 10) of dentigerous and radicular cysts, respectively. EGF reactivity was similar in all cyst groups, weaker than that for TGF alpha and predominantly suprabasal. TGF alpha and EGF were also detected in endothelial cells, fibroblasts and inflammatory cells within the cyst walls. The most intense TGF beta staining in odontogenic cysts was extracellular within the fibrous tissue capsules, irrespective of cyst type. CONCLUSIONS: These results, together with previous studies of EGF receptor, indicate differential expression of TGF alpha, EGF and their common receptor between the different types of odontogenic cyst, suggesting that these growth factors (via autocrine or paracrine, or both, pathways) may be involved in their pathogenesis.

Diagnostic criteria in renal and hepatic cyst infection.  

PubMed

Cyst infection is a severe complication of renal and hepatic cystic disease that frequently leads to hospitalization. In most cases the diagnosis of cyst infection is made empirically as a cyst aspirate is frequently unavailable. This study aims to evaluate diagnostic criteria, microbiological findings and imaging modalities needed to diagnose cyst infection. In order to do so, we evaluated reports that characterize cyst infection cases published in the English language between 1948 and January 2014. We identified 70 articles documenting a total of 215 cyst infection cases (renal n = 119; hepatic n = 96). Six studies, including 74 cases of renal and 61 cases of hepatic cyst infection, used diagnostic criteria. The criteria that led to a definite cyst infection diagnosis were consistent, whereas criteria for a 'probable diagnosis' varied considerably. Cyst infection cases commonly have abdominal pain, fever and elevated serum inflammatory markers. Urine and blood cultures frequently remained negative, even in definite cases. The diagnostic properties of (18)fluorodeoxyglucose positron-emission computed tomography ((18)F-FDG PET/CT) are probably best to diagnose cyst infection. Cyst aspirate indicating infection is currently the gold standard in diagnosing cyst infection. If not available, a combination of clinical and biochemical parameters is necessary to make a well-considered diagnosis, preferably including (18)F-FDG PET/CT. PMID:24950937

There are only 10 other documented cases in the English literature for children under the age of 12. We discuss one such case. A 10-year-old female child with an 8-month history of a midline neck cyst underwent Sistrunk's procedure as surgical treatment after clinical and ultrasound scan confirmation. An incidental 9-mm papillary carcinoma was seen on histology within the thyroglossal cyst. Following multidisciplinary team (MDT) discussion, the child underwent total thyroidectomy and radioiodine ablation. There is no consensus regarding the ideal management for thyroglossal duct carcinoma in the paediatric literature. We discuss the treatment options and the importance of MDT involvement.

Mesenteric dermoid cyst in a child  

PubMed Central

If a pediatric abdominal mass is not organomegaly or colonic stool, narrowing the diagnostic possibilities may be difficult, especially in resource-poor areas where ancillary tests and treatment options may be limited. A 2-year-old girl was brought to the rural Kintampo Municipal Hospital in Ghana with a freely moveable, non-tender abdominal mass. A huge mesenteric dermoid cyst was surgically removed. Mesenteric cysts are rare intra-abdominal lesions, most commonly occurring in children <10 years old. Making a preoperative diagnosis is difficult. Dermoid cysts (mature cystic teratoma) rarely occur in the mesentery. Poverty, family circumstances and the rural location led to general physicians doing surgery. As in this case, due to economic, social and transportation issues common throughout Africa, children with abdominal masses may need at least initial surgery in hospitals without dedicated pediatric surgery or even a trained surgeon.

Combined mutation of Vhl and Trp53 causes renal cysts and tumours in mice  

PubMed Central

The combinations of genetic alterations that cooperate with von Hippel–Lindau (VHL) mutation to cause clear cell renal cell carcinoma (ccRCC) remain poorly understood. We show that the TP53 tumour suppressor gene is mutated in approximately 9% of human ccRCCs. Combined deletion of Vhl and Trp53 in primary mouse embryo fibroblasts causes proliferative dysregulation and high rates of aneuploidy. Deletion of these genes in the epithelium of the kidney induces the formation of simple cysts, atypical cysts and neoplasms, and deletion in the epithelia of the genital urinary tract leads to dysplasia and tumour formation. Kidney cysts display a reduced frequency of primary cilia and atypical cysts and neoplasms exhibit a pro-proliferative signature including activation of mTORC1 and high expression of Myc, mimicking several cellular and molecular alterations seen in human ccRCC and its precursor lesions. As the majority of ccRCC is associated with functional inactivation of VHL, our findings suggest that for a subset of ccRCC, loss of p53 function represents a critical event in tumour development.

Histologic and immunohistochemical characteristics of cutaneous cysts in Goltz-Gorlin syndrome: clues for differentiation of nonsyndromic cysts.  

PubMed

Goltz-Gorlin syndrome presents with multiple basal cell carcinomas, odontogenic keratocysts, and cutaneous cysts, among other manifestations. The cutaneous cysts have been described as both epidermoid cysts and keratocysts but were not further characterized. Light microscopic examinations were made on 23 cutaneous cysts in 4 patients associated with Goltz-Gorlin syndrome located on extremities, face, trunk, palms, and soles and compared with nonsyndromic vellus hair cysts, steatocystomas, and hybrid cysts. Twenty-one of the syndromic cysts revealed alternating infundibular-like and steatocystoma-like squamous epitheliums in varying proportions. The cysts were lined by both smooth and corrugated squamous epithelium. The horny layer was composed by alternating areas of thin, lamellate, and compact eosinophilic keratin. Only 2 cases showed an exclusive steatocystoma-like type of epithelium very similar to odontogenic keratocysts. Sebaceous glands and follicular structures were absent. There were no differences between palmar and plantar cysts and other anatomic locations. The ultrastructural findings in syndromatic cysts confirmed variable expression of keratohyalin granules. Only 3 of 6 cases of nonsyndromic hybrid cysts showed overlapping features with syndromic cysts. Immunohistochemical profiling of keratin, involucrin, filaggrin, loricrin, and BCL-2 expression in syndromatic cysts showed exclusive positivity of K19 and continuous staining for BCL-2. In summary, 2 types of cutaneous cysts are characteristic of Goltz-Gorlin, irrelevant of their anatomic location, namely steatocystoma-like and more frequently hybrid-like. The diagnosis of syndromic hybrid-like cysts should be considered whenever infundibular and steatocystoma differentiation alternate and overlap. Altogether, these findings in epithelial cysts may raise the suspicion of Goltz-Gorlin as an underlying cause. PMID:24698937

Ruptured hydatid cyst in biliary tract.  

PubMed

A lady aged 26 years reported with a 2 months history of fever, upper abdominal pain and weight loss. Her abdominal ultrasonographic scan revealed a complex cystic mass in left lobe of liver suggestive of hydatid cyst that was confirmed on magnetic resonance imaging of abdomen and magnetic resonance cholangiopancreatogram. With strong suspicion of a hydatid cyst, endoscopic retrograde cholangiogram was performed which confirmed the diagnosis. During the procedure, hydatid membranes protruding from the papilla were removed after sphincterotomy. She was put on albendazole 400 mg twice daily after the procedure and showed a remarkable clinical improvement. PMID:23058154

Cysts of the lower male genitourinary tract: embryologic and anatomic considerations and differential diagnosis.  

PubMed

Cysts of the lower male genitourinary tract are uncommon and usually benign. These cysts have different anatomic origins and may be associated with a variety of genitourinary abnormalities and symptoms. Various complications may be associated with these cysts, such as urinary tract infection, pain, postvoiding incontinence, recurrent epididymitis, prostatitis, and hematospermia, and they may cause infertility. Understanding the embryologic development and normal anatomy of the lower male genitourinary tract can be helpful in evaluating these cysts and in tailoring an approach for developing a differential diagnosis. There are two main groups of cysts of the lower male genitourinary tract: intraprostatic cysts and extraprostatic cysts. Intraprostatic cysts can be further classified into median cysts (prostatic utricle cysts, müllerian duct cysts), paramedian cysts (ejaculatory duct cysts), and lateral cysts (prostatic retention cysts, cystic degeneration of benign prostatic hypertrophy, cysts associated with tumors, prostatic abscess). Extraprostatic cysts include cysts of the seminal vesicle, vas deferens, and Cowper duct. A variety of pathologic conditions can mimic these types of cysts, including ureterocele, defect resulting from transurethral resection of the prostate gland, bladder diverticulum, and hydroureter and ectopic insertion of ureter. Accurate diagnosis depends mainly on the anatomic location of the cyst. Magnetic resonance imaging and transrectal ultrasonography (US) are excellent for detecting and characterizing the nature and exact anatomic origin of these cysts. In addition, transrectal US can play an important therapeutic role in the management of cyst drainage and aspiration, as in cases of prostatic abscess. PMID:23842975

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

Suspended Alexandrium spp. hypnozygote cysts in the Gulf of Maine  

NASA Astrophysics Data System (ADS)

The life cycle of dinoflagellates of the genus Alexandrium includes sexual reproduction followed by the formation of a dormant hypnozygote cyst, which serves as a resting stage. Negatively buoyant cysts purportedly fall to the benthos where they undergo a mandatory period of quiescence. Previous reports of cysts in the surficial sediments of the Gulf of Maine, where Alexandrium blooms are well documented, show a broad distribution of cysts, with highest concentrations generally in sediments below 100 m depth. We report here an exploration of cysts suspended in the water column, where they would be better positioned to inoculate springtime Alexandrium populations. During cruises in February, April, and June of 2000, water samples were collected at depths just off the bottom (within 5 m), at the top of the bottom nepheloid layer, and near the surface (1 m) and examined for cyst concentrations. Suspended cysts were found throughout the Gulf of Maine and westernmost Bay of Fundy. Planktonic cyst densities were generally greater in near-bottom and top of the bottom nepheloid layer samples than in near-surface water samples; densities were of the order of 10 2 cysts m -3 in surface waters, and 10 2-10 3 cysts m -3 at near-bottom depths. Temporally, they were most abundant in February and least abundant in April. Reports by earlier workers of cysts in the underlying sediments were on the order of 10 3 cysts cm -3. We present calculations that demonstrate the likelihood of cyst resuspension from bottom sediments forced by swell and tidal currents, and propose that such resuspended cysts are important in inoculating the seasonal bloom. We estimate that suspended cysts may contribute significantly to the annual vegetative cell population in the Gulf of Maine.

Gastric Duplication Cyst Presenting as Acute Abdomen: A Case Report  

PubMed Central

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

Atypical intracranial epidermoid cysts: rare anomalies with unique radiological features.  

PubMed

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. PMID:25667778

Baker's Cyst Filled with Hematoma at the Lower Calf.  

PubMed

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

Video-assisted mediastinoscopic resection of mediastinal cyst (lymphangioma).  

PubMed

Mediastinal cysts account for 20% of all mediastinal masses. Symptomatic cysts need treatment, and surgical excision is the treatment of choice. One approach to resect them is video-assisted mediastinoscopy. An 80-year-old man with cough and dyspnea at rest was referred for evaluation. Chest computed tomography revealed a mediastinal cyst. Because of his symptoms, he was a candidate for surgery, and the cyst was resected by video-assisted mediastinoscopy through a cervical incision. Video-assisted mediastinoscopy is a safe and effective approach for complete resection of mediastinal cysts. PMID:24887894

Ciliated hepatic foregut cysts (CHFCs) are rare congenital cysts of the liver that originate from the embryologic foregut. Despite an increase in incidence, they remain rare and several key characteristics remain poorly understood, including the range of presentation and the risk of malignant conversion. Large, symptomatic cysts and small asymptomatic, atypical cysts should be resected. We present a patient who recently underwent laparoscopic excision of a CHFC, review the literature and propose the rationale for attempting removal of these cysts through a laparoscopic approach.

Head and neck teratoid cysts are the least common congenital cysts in the head and neck region, accounting for approximately 1.8% of all dermoid cysts. Teratoid cysts exhibiting mesodermal elements may be lined by gastric, intestinal, respiratory, squamous, or cilitated epithelium. We present a case of huge submandibular and neck teratoid cyst in newborn with airway obstruction and feeding difficulty. Surgical extirpation is the treatment of choice. However, before operation, some other cystic diseases in the head and neck region needs to be excluded. Fine-needle aspiration biopsy was necessary in differential diagnosis of lesions before treatment, especially that the principle of treatment of those diseases is different. PMID:25723656

Intra cranial hydatid cyst: A case report of total cyst extirpation and review of surgical technique  

PubMed Central

Hydatid cysts commonly affect liver and lung but it can also affect the brain in rare cases. We report a case of 22 year female with history of headache for one and half years. Intracranial hydatid cyst was diagnosed on computed tomography scan and magnetic resonance imaging. The cyst was delivered without rupture using hydrostatic dissection followed by post-operative anthelminthic medication. Surgery remains to be the standard management. Amongst the surgical techniques described, Dowling's technique is the most acceptable. However, care must be taken in to avoid rupture of the cyst peroperatively which can result in subsequent complications and recurrence. Albendazole and corticosteroids can be used as adjunct to surgical treatment in selective cases. PMID:24174780

Xenogenic demineralized bone matrix and fresh autogenous cortical bone effects on experimental bone healing: radiological, histopathological and biomechanical evaluation  

PubMed Central

Background Bone grafting is used to enhance healing in osteotomies, arthrodesis, and multifragmentary fractures and to replace bony loss resulting from neoplasia or cysts. They are source of osteoprogenitor cells and induce bone formation and provide mechanical support for vascular and bone ingrowth. Autografts are used commonly but quantity of harvested bone is limited. The aim of this study is to evaluate autograft and new xenogenic bovine demineralized bone matrix (DBM) effects on bone healing process. Materials and methods Twenty male White New Zealand rabbits were used in this study. In group I (n = 10) the defect was filled by xenogenic DBM and in autograft group the defect was filled by fresh autogenous cortical graft and fixed by cercelage wire. Radiological, histopathological and biomechanical evaluations were performed blindly and results scored and analyzed statistically. Results Statistical tests did not reveal any significant differences between two groups on the 14th postoperative day radiographically (P > 0.05). There was a significant difference for union on 28th and 42nd postoperative days and for remodeling at on the 56th postoperative day radiologically (P < 0.05). Statistical tests did not support any significant differences between two groups for radiological bone formation (P > 0.05). Histopathological and biomechanical evaluation revealed no significant differences between two groups. Conclusions The results of this study indicate that satisfactory healing occurred in rabbit radius defect filled with xenogenic bovine DBM. Complications were not identified and healing was faster, same as in cortical autogenous grafting. PMID:19384620

Laparoscopic treatment of ovarian dermoid cysts is a safe procedure  

PubMed Central

Experienced laparoscopic surgeons should consider laparoscopy as an alternative to laparotomy in management of ovarian dermoid cysts in selected cases. The aim of this study was to analyze the safety of laparoscopy in ovarian dermoid cysts treatment and risk of chemical peritonitis. We report 63 cases of patients (mean age of 37) with ovarian dermoid cysts originating from the ovary, treated from 2002 to 2010. Most of the patients underwent cysts removal. In 7 patients salpingo-oophorectomy was performed. We used 15 mm trocars for removing specimens. In patients with dermoid cyst rupture peritoneal cavity was washed out thoroughly with Ringer lactate and drained for 24-48 hours. All the material extracted was sent for a histopathology examination. The diagnosis of mature ovarian dermoid cysts was confirmed in 58 (92.63%) of cases and immature ovarian dermoid cysts in 5 (7.37%) cases. Dermoid cysts were composed of tissue developed from three germinative layers in 31 (49%) patients, from two germinative layers in 25 (40%), and in 7 (11%) patients from one germinative layer. No intra or postoperative complications occurred. No signs or symptoms of chemical peritonitis were observed regardless of cystic spillage or not. We conclude that the risk of chemical peritonitis can be minimized when undertaking laparoscopic removal of ovarian dermoid cysts if the peritoneal cavity is washed out thoroughly from spillage of cyst contents. Drainage of peritoneal cavity should be performed in the patients with the ruptured dermoid cysts. PMID:22117832

Hydatid cyst disease is endemic in our country. This disease is most commonly detected in the liver and lung, but it can be detected rarely in the soft tissue, muscles and subdermally. In this study, we mentioned a case with subcutaneous hydatid cyst disease without any primary lesion. In this case, a left lumbar subdermal cyst was totally excised and the germinative membrane of the cyst was detected and sent for pathological examination and study resultsreported hydatid cyst disease. The patient was followed up for one year with laboratory and radiological studies. No recurrent hydatid cyst was observed. Turkey is an endemic area for hydatid cyst disease and we should bear this disease in mind as a differential diagnosis in all cystic lesions. PMID:24659704

The hydatid cyst of the diaphragm is defined as the development of a hydatid cyst in the diaphragm muscle. The purpose of this study is to identify the specific pathogenic, clinical and therapeutic aspects of this hydatid cyst. It is important to confirm the diagnosis of the location before surgery. We report the case of a patient aged 40 years, in whom the diagnosis of hydatid cyst of the diaphragm was made incidentally in the course of a gastric stromal tumour. The patient was operated by a midline laparotomy. Resection of the protruding dome of hydatid cyst of the diaphragm was carried out along with total gastrectomy. The postoperative course was uneventful. After 12 months, the results were negative. The diagnosis of hydatid cyst of the diaphragm is based on the thoraco-abdominal CT scan. The treatment is surgical based on the topographic features of the cyst. PMID:22354550

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.

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.

Tarlov cysts: an overlooked clinical problem.  

PubMed

Symptomatic Tarlov cysts typically cause chronic pelvic and lower extremity pain and sacral nerve root radiculopathy. Historically, open surgical treatment involved significant patient morbidity, particularly postoperative cerebrospinal fluid (CSF) leaks and infection. These CSF leaks often required multiple surgical procedures to seal. Over the past 20 years, there have been two or three isolated case reports of computed tomography (CT)-guided needle aspirations that offered limited evidence of treatment efficacy and safety. Some have reported high rates of postprocedure aseptic meningitis that were not well explained. These poor results dissuaded physicians from caring for these patients. As a group these patients are usually treated dismissively and told their cysts are asymptomatic and their pain must be coming from somewhere else. Many of them have had an unnecessary discectomy or a spinal fusion, and when these procedures did not relieve their pain they were told they are a "failed back patient." We have treated more than a hundred patients with symptomatic Tarlov cysts by CT fluoroscopic-guided needle aspiration and fibrin injection and have had excellent results with no meaningful complications and never a case of aseptic meningitis. We believe this is a safe, highly effective first-line treatment for symptomatic Tarlov cysts. PMID:21500136

Conservative versus radical surgery for treatment of uncomplicated hepatic hydatid cysts.  

PubMed

This work evaluated both radical and conservative surgical approaches in the management of hepatic hydatid cyst. A total of 32 cases with uncomplicated hepatic hydatid cysts were divided into 2 groups according to the type of surgery. Patients in the first group (n=18) were subjected to conservative surgery in the form of endocystectomy, omentoplasty with or without drainage. Cases in the second group (n=14) underwent radical surgery that included closed pericystectomy, open pericystectomy, wedge hepatic resection or segmentectomy. The results showed that the use of rib cage retractor could avoid the need for thoracotomy incision with its morbidity to manage cysts at the dome of the liver. The mean operating time in GI (140.15 +/- 38.30 min) was significantly shorter than in GII (190.4 +/- 50.2 min), with P< 0.05. The need of blood transfusion in GI (16.7%) was lesser than in GII (35.7%), but the difference was statistically not significant. The postoperative pain, evaluated by the number of IM analgesic injection was significantly lower in GI (7.2 +/- 3.3) than in GII (9.9 +/- 3.9) with P < 0.05. Wound complications were more observed in GII. There was only one reported recurrence in GI in a case with multiorgan cysts that did not receive perioperative anthelmintic chemotherapy. So, conservative surgical management of uncomplicated hepatic hydatid cysts with perioperative anthelmintic chemotherapy supposed to be a simple, safe and effective approach. Its efficacy is comparable to radical surgical procedures with much less morbidity. PMID:16927868

Impact of bone geometry on effective properties of bone scaffolds.  

PubMed

The characterization of bone/scaffold composite mechanical properties is essential for translation to the clinic, but in vivo studies require resources and personnel not available to many investigators. Therefore, the ability to predict composite properties could facilitate scaffold evaluation and reduce the number of in vivo studies required. To date, there have been no studies that have used experimental data to formulate a model of bone morphology or that have examined morphology as a variable in composite properties. In this study, a simple model was developed to predict the effective elastic properties of hydroxyapatite (HA) scaffold/bone composites using representative volume elements (RVE) and finite element analysis. While the RVE for the scaffold is clear, the choice of RVE for bone is not. Two bone geometries were generated for the RVE based on data from an in vivo study: a uniform coating and bridges in pores. Three scaffolds were evaluated in order to consider the effects of scaffold material modulus and porosity. Results showed that the bone geometry had little influence on composite elastic properties when compared to experimental error from the in vivo study. The implication is that such properties can be estimated by measuring the volume fraction of bone using a non-destructive method like microcomputerized tomography and the simple RVE model.

Bilateral Radicular Cyst in Mandible: An Unusual Case Report  

PubMed Central

A radicular cyst is one of the furthermost everyday odontogenic cysts of the anterior maxilla, not regularly comprehended in youth. They are found mostly at the apices of the tooth (periapical cyst), lateral surface of the roots (lateral radicular cyst) and remains in the jaw after removal of the offending tooth (residual cyst). The radicular cyst has been catalogued as an inflammatory cyst, as an outcome to pulpal necrosis succeeding caries, with a linked periapical inflammatory reaction. They advance sluggishly and asymptomatic lest infected. Because of this they can extent to big dimensions. Many times it is perplexing to segregate radicular cysts from the obligatory pre-existing chronic periapical periodontitis lesions radiographically. Here, we present a rare case with bilateral radicular cyst in relation to first molar of the mandible in a 19-year-old. Orthopantomograph showed a large unilocular radiolucency with a well-defined border in the periapical region of the first molar on the left side extending from the root of the second premolar to the mesial root of the second molar. Correspondingly another well-defined unilocular radiolucency with a well-defined border was seen on the right side of the mandible. Several treatment possibilities are presented for a radicular cyst such as surgical endodontic treatment, extraction of the transgressing tooth, enucleation with primary closure, and marsupialization trailed by enucleation. The patient management comprised surgical enucleation of cystic sac followed by rehabilitation of the same area.

CD56 Expression in Odontogenic Cysts and Tumors.  

PubMed

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. It could be interesting to find out why cereal cysts are suppressed in our regions and to expand the survey to the Walloon region where more cereals are grown. PMID:20222621

Carbohydrate and amino acid analyses of Giardia muris cysts.  

PubMed

Intact Giardia muris cysts were subjected to consecutive chloroform/methanol and 2% sodium dodecyl sulfate (SDS) extractions, and to amyloglucosidase treatment. The SDS-insoluble, amyloglucosidase-fast cyst walls (ACW) were further incubated with chymotrypsin, trypsin, papain, or pronase. Low voltage scanning electron microscopy revealed no discernible change in the ultrastructure of the filamentous layer of the cyst wall following any of these treatments. Affinity for cyst wall-specific monoclonal antibody (Meridian Diagnostics, Cincinnati, OH) was also retained after all treatments. Periodic acid-Schiff staining and gas chromatography/mass spectrometry (GC/MS) of intact and treated cyst hydrolysates showed a significant reduction in the amount of glucose associated with the cyst (72 nmoles/10(6) intact cysts vs 1.9 nmoles/10(6) ACW) as a result of amyloglucosidase treatment, indicating that glucose is stored within Giardia as an SDS-insoluble polymer. Galactosamine was identified by GC/MS as the predominant sugar associated with both the ACW and the proteinase treated ACW (42 nmoles/10(6) ACW). High performance liquid chromatographic analysis of amino acids from intact and treated cyst hydrolysates revealed a marked reduction, but not elimination, of detectable quantities of identifiable amino acid residues (255 nmoles/10(6) intact cysts vs 6.8 nmoles/10(6) proteinase treated ACW). These results suggest that the filamentous layer of the cyst wall is primarily a carbohydrate peptide complex. PMID:1578402

Comparison of Giardia lamblia and Giardia muris cyst inactivation by ozone.  

PubMed Central

Inactivation of Giardia lamblia and Giardia muris cysts was compared by using an ozone demand-free 0.05 M phosphate buffer in bench-scale batch reactors at 22 degrees C. Ozone was added to each trial from a concentrated stock solution for contact times of 2 and 5 min. The viability of the control and treated cysts was evaluated by using the C3H/HeN mouse and Mongolian gerbil models for G. muris and G. lamblia, respectively. The resistance of G. lamblia to ozone was not significantly different from that of G. muris under the study conditions, contrary to previously reported data that suggested G. lamblia was significantly more sensitive to ozone than G. muris was. The simple Ct value for 2 log unit inactivation of G. lamblia was 2.4 times higher than the Ct value recommended by the Surface Water Treatment Rule. PMID:8285675

Alexandrium minutum resting cyst distribution dynamics in a confined site  

NASA Astrophysics Data System (ADS)

The life cycle of the toxic dinoflagellate Alexandrium minutum consists of an asexual stage, characterized by motile vegetative cells, and a sexual stage, a resting cyst that once formed remains dormant in the sediment. Insight into the factors that determine the distribution and abundance of resting cysts is essential to understanding the dynamics of the vegetative phase. In investigations carried out between January 2005 and January 2008 in Arenys de Mar harbor (northwestern Mediterranean Sea), the spatial and temporal distribution patterns of A. minutum resting cysts and of the sediments were studied during different bloom stages of the vegetative population. Maximum cyst abundance was recorded mainly in the innermost part of the harbor while the lowest abundance always occurred near the harbor entrance, consistent with the distribution of silt-clay sediment fractions. The tendency of cysts in sediments to increase after bloom periods was clearly associated with new cyst formation, while cyst abundance decreased during non-bloom periods. Exceptions to this trend were observed in stations dominated by the deposition of coarse sediments. High correlation between the presence of cysts and clays during non-bloom periods indicates that cysts behave as passive sediment particles and are influenced by the same hydrodynamic processes as clays. In Arenys de Mar, the main physical forcing affecting sediment resuspension is the seiche, which was studied using in situ measurements and numerical models to interpret the observed distribution patterns. During non-bloom periods, cyst losses were smaller when the seiche was more active and at the station where the seiche-induced current was larger. Thus, seiche-forced resuspension appears to reduce cyst losses by reallocating cysts back to the sediment surface such that their burial in the sediment is avoided. The observed vertical profiles of the cysts were consistent with this process.

A Boon for Bone Research  

NASA Technical Reports Server (NTRS)

NASA studies for astronaut health in long-term space missions led to the development of the Mechanical Response Tissue Analyzer (MRTA), a research tool for astronaut disuse, osteoporosis and related bone disorders among the general population. Ames Research Center and Stanford University generated a workable device and with Gait Scan, Inc., refined and commercialized it. The MRTA is a portable dsinstrument that measures the bending stiffness of bones using electrically-induced vibration and detects and analyzes the frequencies of the resonating bone. Unlike some other methods, the MRTA uses no radiation and is fast, simple and relatively inexpensive.

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.

Choledochal cyst- Presentation of the disease with a case report  

PubMed Central

Choledochal cyst is a rare disease of the biliary tract. There are five main types of choledochal cysts with a few recognized sub-types. The etiology of choledochal cysts still is unclear. The incidence of biliary tract cancer in patients with choledochal cysts increases with age. In the past, choledochal cysts were often treated using drainage procedures; however, the optimal treatment used today is likely to involve the complete excision of the extrahepatic duct, cholecystectomy, and Roux-en-Y hepaticojejunostomy. Endoscopic treatment of type III choledochocele should be limited to the management of smaller lesions. We report a case of 75 years old patient with distal choledochal diverticuly, Todani’s type III- choledochocele. Delay in the diagnosis increases the frequency of associated biliary pathology, malignant alternation and suboptimal surgical therapy. Often, intraoperative finding of choledochal cyst is the first contact with this rear entity, so awareness of possible presence of this uncommon disease is very important for surgeon. PMID:21875424

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

Rupture of right hepatic duct into hydatid cyst.  

PubMed

Echinococcal disease can develop anywhere in the human body. The liver represents its most frequent location. Hepatic hydatid cysts may rupture into the biliary tract, thorax, peritoneum, viscera, digestive tract or skin. We report a rare case with rupture of the right hepatic duct into a hydatid cyst in a woman with known hydatid disease and choledocholithiasis. The increased intra-luminal pressure in the biliary tree caused the rupture into the adjacent hydatid cyst. The creation of the fistula between the right hepatic duct and the hydatid cyst decompressed the biliary tree, decreased the bilirubin levels and offered a temporary resolution of the obstructive jaundice. Rupture of a hydatid cyst into the biliary tree usually leads to biliary colic, cholangitis and jaundice. However, in case of obstructive jaundice due to choledocholithiasis, it is possible that the cyst may rupture by other way around while offering the patient a temporary relief from his symptoms.

Transurethral deroofing of midline prostatic cyst for subfertile men.  

PubMed

We evaluated the efficacy of transurethral deroofing of a midline prostatic cyst in subfertile men with one or more of the following semen abnormalities: decreased ejaculatory volume, decreased sperm motility and oligo- or azoospermia. Results from treatment of a series of 11 subfertile men with a midline prostatic cyst by transurethral deroofing of the cyst are presented. Five patients showed an improvement of seminal volume. Only one patient demonstrated an improvement of sperm count. Sperm motility was not influenced. No relationship was found between positive outcome following operation and either size of the cyst or dilatation of the seminal vesicles. Spontaneous pregnancies did not occur after transurethral deroofing of the midline prostatic cyst. In conclusion, our study suggests a poor efficacy of transurethral deroofing of a midline prostatic cyst in subfertile men with the above mentioned semen abnormalities. PMID:10469699

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.

Hydatid cyst of the parotid gland.  

PubMed

Primary hydatid cyst of the parotid gland is extremely rare, even in the endemic areas. A 23-year-old woman presented with slowly progressive swelling in the right periauricular region. Computed tomography (CT) scan of the head and neck revealed a round, well-demarcated water-density mass in the right parotid gland. At the operation, the cystic mass replacing most of the superficial part of right parotid gland was demonstrated. Superficial parotidectomy was carried out. Histopathological examination confirmed the diagnosis of hydatid disease. CT scan is a valuable imaging method for diagnosis of parotid cystic lesions; however, other acquired and congenital cystic lesions of parotid gland may have similar appearance and should be differentiated. Where the incidence of the disease is high, hydatid cyst of parotid gland should be considered in the differential diagnosis of lesions causing swelling of the parotid area. PMID:18979123

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

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

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

Pulmonary echinococcosis (hydatid disease) is not rare in endemic regions. In Poland it is rare, seen mainly in subjects returning from endemic areas. The intermediate host includes a variety of mammals-sheep, cows, and also humans. The definite host is the dog and is the main source of ova. A case of a 52 year old male is presented who lived in Argentina for a few years. Radiological examination disclosed two pulmonary cysts. Additionally one was also present in the spleen. The diagnosis was made basing of findings form radiological examinations. CT-scan, and serological studies. It was further confirmed during the surgical removal of the affected lung parenchyma. Leaving the spleen cysts is a risk factor it may be the source for further seeding of ova. Mebendazol therapy was instituted, which will be continued in the future.

We studied data from 80 paediatric patients with 55 Baker cysts, examined over a period of 7 years, and correlated clinical presentation with findings on ultrasonography and MRI. Prevalence of popliteal cysts was 57% in arthritic knees, 58% with hypermobility syndrome, and 28% without risk factors. Only one patient had a trauma history and showed an ipsilateral cyst. Mean cyst volume was 3.4?mL; cysts were larger in boys. Patients with arthritis had echogenic cysts in 53%. Cyst communication with the joint space was seen in 64% on ultrasonography and 86% on MRI. In conclusion, Baker cysts are a common finding in a clinically preselected paediatric population. Children with Baker cysts should be assessed for underlying arthritis and inherited joint hypermobility, while sporadic Baker cysts appear to be common, as well. PMID:22046524

Cyclic AMP-Mediated Cyst Expansion  

PubMed Central

In polycystic kidney disease (PKD), intracellular cAMP promotes cyst enlargement by stimulating mural epithelial cell proliferation and transepithelial fluid secretion. The proliferative effect of cAMP in PKD is unique in that cAMP is anti-mitogenic in normal renal epithelial cells. This phenotypic difference in the proliferative response to cAMP appears to involve cross-talk between cAMP and Ca2+ signaling to B-Raf, a kinase upstream of the MEK/ERK pathway. In normal cells, B-Raf is repressed by Akt (protein kinase B), a Ca2+-dependent kinase, preventing cAMP activation of ERK and cell proliferation. In PKD cells, disruption of intracellular Ca2+ homeostasis due to mutations in the PKD genes relieves Akt inhibition of B-Raf, allowing cAMP stimulation of B-Raf, ERK and cell proliferation. Fluid secretion by cystic cells is driven by cAMP-dependent transepithelial Cl? secretion involving apical cystic fibrosis transmembrane conductance regulator (CFTR) Cl? channels. This review summarizes the current knowledge of cAMP-dependent cyst expansion, focusing on cell proliferation and Cl?-dependent fluid secretion, and discusses potential therapeutic approaches to inhibit renal cAMP production and its downstream effects on cyst enlargement.

Subcutaneous phaeohyphomycotic cyst caused by Pyrenochaeta romeroi.  

PubMed

Pyrenochaeta romeroi is a rare agent of chronic, suppurative subcutaneous infections which ultimately lead to mycetoma. It has only rarely been reported from deep, non-mycetomatous infections. We describe a case of a subcutaneous phaeohyphomycotic cyst in a 45-year-old Indian female who suffered from verrucous plaque and a swelling (30 mm in diameter) on the right forearm that gradually increased in size over a period of 3 months. Direct microscopic examination with 10% KOH and histopathological investigation of exudates revealed septate hyphae without granules, the hallmark of mycetoma. The lesion appeared to be a subcutaneous phaeohyphomycotic cyst caused by P. romeroi. The suspected agent was recovered in culture, identified on the basis of morphologic features and its identification confirmed by sequencing of the internal transcribed spacer regions of rDNA. Treatment consisted of surgical excising of the cyst without any antifungal therapy. There was no relapse during a one-year follow-up and the patient was successfully cured. In vitro antifungal susceptibility tests demonstrated that itraconazole (0.5 microg/ml), isavuconazole (0.125 microg/ml) and posaconazole (0.5 microg/ml) had potent activity against this isolate of P. romeroi. High MICs were found with amphotericin B (4 microg/ml), fluconazole (>64 microg/ ml), voriconazole (4 microg/ml) and caspofungin (8 microg/ml). However, their clinical effectiveness in the treatment of P. romeroi infections remains to be evaluated. PMID:20648971

A clinical report demonstrating the significance of distinguishing a nasopalatine duct cyst from a radicular cyst.  

PubMed

Endodontic diagnosis is challenging and depends on the organisation of information from the patient history, clinical examination and analysis of the pulp, radiographic and histopathological assessment. A 35-year-old man was endodontically treated for radiolucency in relation to the roots of maxillary central incisors as it was a provisionally diagnosed case of radicular cyst. Since the palatal swelling persisted, the lesion was re-evaluated using relevant diagnostic aids and a diagnosis of nasopalatine duct cyst (NPDC) was made, which was missed during the initial assessment. An erroneous interpretation of cystic radiolucency in relation to maxillary central incisors can often lead to inappropriate treatment planning. This case highlights the relevant aspects in the diagnosis of NPDC when it is mistaken for a radicular cyst and emphasises the need for thorough clinical examination and relevant investigations for periapical radiolucencies of questionable origin before initiating endodontic therapy.

Automated classification of four types of developmental odontogenic cysts.  

PubMed

Odontogenic cysts originate from remnants of the tooth forming epithelium in the jaws and gingiva. There are various kinds of such cysts with different biological behaviours that carry different patient risks and require different treatment plans. Types of odontogenic cysts can be distinguished by the properties of their epithelial layers in H&E stained samples. Herein we detail a set of image features for automatically distinguishing between four types of odontogenic cyst in digital micrographs and evaluate their effectiveness using two statistical classifiers - a support vector machine (SVM) and bagging with logistic regression as the base learner (BLR). Cyst type was correctly predicted from among four classes of odontogenic cysts between 83.8% and 92.3% of the time with an SVM and between 90 ± 0.92% and 95.4 ± 1.94% with a BLR. One particular cyst type was associated with the majority of misclassifications. Omission of this cyst type from the data set improved the classification rate for the remaining three cyst types to 96.2% for both SVM and BLR. PMID:24411103

Appearance can be deceptive: Dentigerous cyst crossing the midline  

PubMed Central

Dentigerous cyst is a developmental odontogenic cyst, which develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. Dentigerous cysts are usually solitary, slow growing, asymptomatic lesions that are incidentally found during routine radiographs They most frequently involve the mandibular third molar followed in order of frequency by the maxillary canine, mandibular second pre-molar and maxillary third molar. Occasionally, these cysts become painful when infected causing swelling and erythema. The cyst is usually small, however, when large, results in the expansion and thinning of the cortex leading to pathological fracture. Radiographic features are specific to the lesion characterized by a well-defined radiolucency circumscribed by a sclerotic border, associated with the crown of an impacted or unerupted tooth. Dentigerous cysts are treated most commonly by enucleation, Marsupialization and decompression of cyst by fenestration. The criteria for selecting the treatment modality is based on the age, size, location, stage of root development, position of the involved tooth and relation of the lesion to the adjacent tooth and vital structure. The prognosis is an excellent when the cyst is enucleated and recurrence is rare. In this article, we present a case of a Dentigerous cyst in an 80-year-old man in the anterior aspect of the mandible enveloping an impacted canine and crossing the midline but with no clinical expansion or discomfort.

A huge renal cyst mimicking ascites: a case report  

PubMed Central

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.

Arthroscopic cystectomy for popliteal cysts through the posteromedial cystic portal.  

PubMed

In the treatment of patients with popliteal cysts (Baker's cysts), we generally need to address the intra-articular pathologies, most commonly, medial meniscal tears and concomitant connecting valvular mechanisms responsible for the formation and recurrence of the cyst. We introduce here an arthroscopic technique that can treat the associated intra-articular pathology and correct the valvular mechanism of the capsular fold. The most important step is to locate the opening connection between the joint cavity and the popliteal cyst at the posteromedial compartment. The opening is found at the posteromedial side of the medial head of the gastrocnemius after inferior displacement of the capsular fold, which overlies the opening. It is helpful to rotate the bevel of the arthroscope upward to the 11-, 12-, and 1-o'clock positions for most effective visualization of the capsular fold. After the opening connection of the cyst is found, the capsular fold is resected with basket forceps and a shaver inserted through the posteromedial portal to correct the valvular mechanism. Furthermore, we have developed an additional "posteromedial cystic portal," which is located directly above the popliteal cyst and can be effectively used in cystectomy, especially in treatment of cysts that consist of septa and nodules. Arthroscopic popliteal cyst removal with use of an additional posteromedial cystic portal can be effective in treating a cyst with multiple fibrous septa or membranes. PMID:17478291

[Percutaneous treatment of the liver hydatid cysts under sonographic guidance].  

PubMed

This paper is a retrospective study of the first 51 cases of liver hydatid cysts, which underwent a conservative treatment between April 1996-December 2000. There were 28 females and 23 males with a mean age of 40.1 years (7-65), which had 63 liver hydatid cysts. In the right liver lobe were located 46 cysts, in the left liver lobe were located 7 cysts and in 10 cases cysts were located in both liver lobes. In 4 cases a pulmonary hydatidosis was associated. Abdominal ultrasound and CT scan were routinely performed and the cysts were classified in type I and II after Gharbi's classification. All of these 63 cysts were treated by ultrasound guided fine-needle percutaneous puncture with aspiration and instillation of sterile alcohol 95 degrees. Pre and postoperative the patients were treated with mebendazol or albendazol. They were followed-up by ultrasound and CT scan examination in the second day postoperative and monthly. No new cysts were noted during an average follow-up of 14.7 months and maximal cyst diameter decreased with minimum 72%. Two episodes of reversible anaphylaxis were encountered. The mean hospital stay was 3.3 days. In this paper the indications for conservative treatment and preliminary results of this method are discussed. PMID:12731228

First record of cysts in the tidal tardigrade Echiniscoides sigismundi  

NASA Astrophysics Data System (ADS)

Tardigrades are microscopic metazoans that withstand environmental extremes by entering dormant states, such as cryptobiosis (latent life). In addition, they may also form cysts. Here, we present the first report of cyst formation in a marine heterotardigrade, i.e., Echiniscoides sigismundi, which constitutes a cryptic species complex present worldwide in tidal zones. The cysts were initially discovered during experimental series constructed to investigate osmotic stress tolerance. The animals, which eventually formed cysts, showed signs of an imminent molt at the beginning of experimentation. We use the term "cyst" for stages, where a total of three or more cuticles have been synthesized. Our observations show that encystment in E. sigismundi involves synthesizing of at least two new cuticle layers. Legs with discharged claws are present in connection with the first outer cuticle, as well as the second cuticular layer. In the most developed cyst, a third cuticle lacking claws seems to surround the animal, which is delineated by a fourth cuticle. Many features are shared with the well-studied cysts of eutardigrades. The cysts of E. sigismundi, however, lack pigmentation and have an extra set of claws, and the animal inside retains buccopharyngeal sclerified parts, until discharging the third cuticle. The finding of cysts in a marine heterotardigrade is novel and confirms that encystment also occurs within this major evolutionary lineage.

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.

Posterior fossa arachnoid cysts in adults: Surgical strategy: Case series  

PubMed Central

Introduction and Aim: The management of posterior fossa arachnoid cyst (PFAC) in adults is controversial. To review our cases and literature, propose a practically useful surgical strategy, which gives excellent long-term outcome in management of PFAC. Materials and Methods: We analyzed our case records of 26 large intracranial arachnoid cysts in adults treated over 12 years. Of them, we had 7 patients with symptomatic PFAC. Reviewed the literature of 174 PFAC cases (1973–2012) and added 7 of our new cases with a follow-up ranging from 3 to 12 years. Results: In 6 cases the PFAC was located in the midline. In the 7th case, it was located laterally in the cerebello-pontine (CP) angle. All patients were treated surgically. Excision of the cyst was performed in 5 of these cases. Among the two intra-fourth ventricular cysts, in both the cases cysto-peritoneal shunt was performed. Postoperative computed tomography/magnetic resonance imaging showed variable decrease in size of the cyst even though clinically all patients improved. We propose a surgical strategy for the management of these cases which would aid the surgeon in decision making. Discussion: We observed that these PFACs can occur either in the midline within the fourth ventricle or retroclival region or extra-fourth ventricular region. It can also develop laterally in the CP angle or behind the cerebellum or as intracerebellar cyst. Importance of this is except for Midline Intra-fourth ventricular cyst/retroclival cyst, the rest all can be safely excised with excellent long term outcome. The treatment strategy for Midline Intra-fourth ventricular cyst/retroclival cyst can be either cysto-peritoneal shunt or endoscopic fenestration of the cyst.

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

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

Calcifying odontogenic cyst immunohistochemical detection of keratin and involucrin in cyst wall  

Microsoft Academic Search

Calcifying odontogenic cysts (COC) were immunohistochemically described using different keratin proteins and involucrin as well as histopathology. The cystic lining epithelium was composed of calcifying, keratinizing, squamous, and columnar epithelial cells, and included calcified masses of irregular shape and various size as well as ghost cells. Calcifying epithelium gave negative or only trace staining for keratins detected with low molecular
