1/325. papilledema associated with a sacral intraspinal cyst.A rare case of papilledema associated with a large sacral intraspinal cyst is described in a 34-year-old male. Symptoms were aggravated by heavy work and consisted of low back pain, headache, dizziness and episodic vomiting. papilledema was observed on ophthalmological examination. A valvular mechanism was found to exist between the normal spinal sac and the huge sacral cyst. Division of the valvular fistula combined with a dural plastic operation brought complete relief of all symptoms.- - - - - - - - - - ranking = 1keywords = dura (Clic here for more details about this article) |
2/325. Mesothelial splenic cyst--a case report.A 26-year-old male presented with a left upper abdominal mass of one year's duration. ultrasonography revealed a cystic lesion arising from the lower pole of the spleen. Total splenectomy was done and pathological examination of the cyst confirmed a true cyst with mesothelial lining without squamous metaplasia. The epithelial linings of these true cysts ranged from flattened low cuboidal, low columnar to squamous type and unilayered or stratified. The pathogenetic hypotheses as well as clinicopathological features of this rare lesion, which is usually found in children and young adults, were reviewed.- - - - - - - - - - ranking = 1keywords = dura (Clic here for more details about this article) |
3/325. Retrodural cysts bridging a bilateral lumbar spondylolysis: a report of two symptomatic cases.We report the MR features in two patients presenting with symptomatic thecal impingement by posterior epidural cysts linking a bilateral lumbar spondylolysis. Large fluid-filled channels bridging the ruptured partes interarticulares were present in spite of the absence of significant arthritic changes within the adjacent facet joints.- - - - - - - - - - ranking = 5keywords = dura (Clic here for more details about this article) |
4/325. MR imaging of a hemorrhagic and granulomatous cyst of the ligamentum flavum with pathologic correlation.cysts of the ligamentum flavum are uncommon causes of neurologic signs and symptoms and usually are seen in persons over 50 years of age. We report a case of an epidural cyst located in the ligamentum flavum, which contributed to spinal stenosis in a 30-year-old man. Radiologic features were similar to those of a synovial cyst, but synovium was not identified histologically. The imaging and pathologic features were unusual, including hemorrhage and a fibrohistiocytic reaction with giant cells.- - - - - - - - - - ranking = 1keywords = dura (Clic here for more details about this article) |
5/325. Intraspinal extradural cysts communicating with adjacent herniated disks: imaging characteristics and possible pathogenesis.We report two cases of intraspinal extradural cysts communicating with an adjacent herniated disk that we term "disk cysts." These cysts were well defined and homogeneous, and were present in the ventrolateral extradural space adjacent to a lumbar herniated disk. They had rim enhancement on contrast-enhanced MR images, and communication with a herniated disk was revealed by diskography.- - - - - - - - - - ranking = 6keywords = dura (Clic here for more details about this article) |
6/325. ehlers-danlos syndrome associated with multiple spinal meningeal cysts--case report.A 40-year-old female with ehlers-danlos syndrome was admitted because of a large pelvic mass. Radiological examination revealed multiple spinal meningeal cysts. The first operation through a laminectomy revealed that the cysts originated from dilated dural sleeves containing nerve roots. Packing of dilated sleeves was inadequate. Finally the cysts were oversewed through a laparotomy. The cysts were reduced, but the postoperative course was complicated by poor wound healing and diffuse muscle atrophy. ehlers-danlos syndrome associated with spinal cysts may be best treated by endoscopic surgery.- - - - - - - - - - ranking = 1keywords = dura (Clic here for more details about this article) |
7/325. Multicystic autoimmune thyroiditis-like disease associated with hiv infection. A case report.BACKGROUND: Human immunodeficiency virus (hiv) infection and resulting acquired immunodeficiency syndrome (AIDS) may involve virtually every organ system, including the endocrine glands. Thyroid dysfunction most commonly reflects advanced disease and generally resembles euthyroid sick syndrome. Rarely do opportunistic infections, hemorrhage, neoplasms and drugs account for alterations in thyroid tissue. Multiple lymphoepithelial cysts of parotid gland and thymus have been identified, but similar findings in thyroid gland have not been reported. CASE: A 41-year-old, hiv-seropositive woman, asymptomatic for seven years, developed a squamous cell carcinoma of the cervix with local-regional extension. At the same time, bilateral complex thyroid cysts and high titers of antimicrosomal antibodies (1/6,400) were detected. Ultrasound-guided fine needle aspiration biopsy of the thyroid showed a heterogeneous lymphocytic population with a reactive appearance and occasional groups of epithelial cells with an immature squamous pattern, along with cytologic features of autoimmune thyroiditis. Immunocytochemistry was positive for CD20, CD3 and CD5. Immunoglobulin heavy chain gene rearrangement by polymerase chain reaction from cytologic material showed a polyclonal lymphoid population. External radiotherapy resulted in a significant reduction in the pelvic lesion. Four months after diagnosis, abdominal ultrasound displayed multiple hepatic metastasis, the patient's condition rapidly deteriorated, and she died about a month later. CONCLUSION: This case had unique features and probably represented an AIDS-related lesion and distinct entity.- - - - - - - - - - ranking = 3.3605102420869keywords = mater (Clic here for more details about this article) |
8/325. Sagittal sinus occlusion by intraluminal dural cysts. Report of two cases.Lesions involving the sagittal sinus typically present as masses compressing the sinus externally. The authors describe two cases of lesions entirely within the lumen of the sagittal sinus. In one of the cases, syncope was the presenting symptom and surgical resection of the cyst was performed. An entirely intraluminal cyst, consistent with a dural cyst, was resected, followed by reconstruction of the sinus and resolution of symptoms. Entirely intraluminal lesions of the sagittal sinus have rarely been reported as incidental findings. This represents the first report of symptomatic occlusion of a venous sinus by an intraluminal cyst.- - - - - - - - - - ranking = 5keywords = dura (Clic here for more details about this article) |
9/325. Gasless laparoscopy under epidural anesthesia for adnexal cysts during pregnancy.OBJECTIVE: To evaluate laparoscopic adnexal cystectomy during pregnancy using an open technique with a whole abdominal wall-lift method under epidural anesthesia. STUDY DESIGN: Seven cases of adnexal cysts during pregnancy were resected using a gasless laparoscopic (extracorporeal) method with a whole abdominal wall-lift. We performed this procedure without using general anesthesia or CO2 pneumoperitoneum. RESULTS: All operations were performed successfully without complications. All patients resumed normal activity within one week. The subsequent antenatal courses of the patients were uneventful. There were no severe complications during the operations or postoperative courses. Six patients had vaginal deliveries of normal infants at term. No abnormal findings were found in the antenatal course of patient 7 until 30 weeks of gestation. CONCLUSION: Based on our limited experience, this procedure may be safe.- - - - - - - - - - ranking = 5keywords = dura (Clic here for more details about this article) |
10/325. Intracerebral cyst associated with meningioma.A 27-year-old male had experienced an episode of severe headache and nausea, sometimes accompanied by an inability to name objects. magnetic resonance imaging showed a huge cyst within the left temporal lobe and a high degree of brain shift by it. A small round mass, which appeared to be a mural nodule, was located in the tip of left middle fossa. It was highly enhancing together with its attached dura mater, but the cyst wall was not enhanced. Sphenoid ridge meningioma with an associated intracerebral cyst or cystic glioma invading the dura mater was suspected. During surgery the small tumor was found to be arising from the sphenoid ridge and evaginating into the tip of the temporal lobe. The intracerebral cyst had a smooth surface and the tumor was visible outside the cyst through its wall. The tumor was totally removed, but the cyst wall was left without excision. Postoperatively he had no symptoms. Histological examination showed a microcystic meningioma. It is stressed that differentiations of cystic meningiomas from other cystic tumors and, of intratumoral from extratumoral cystic meningiomas using radiological, operative or histological findings are important.- - - - - - - - - - ranking = 33.439466575052keywords = dura mater, mater, dura (Clic here for more details about this article) |
