1/268. peroneal nerve palsy caused by intraneural ganglion.A case of peroneal nerve palsy caused by an intraneural ganglion is presented. The cystic mass was located posterolateral to the lateral femoral condyle and extended along the common peroneal nerve distal to the origin of the peroneus longus muscle. The nerve was compressed in the narrow fibro-osseous tunnel against the fibula neck and the tight origin of the peroneus longus muscle. The nerve was decompressed by complete tumor excision and transection of the origin of the peroneus longus muscle. Full recovery of nerve function was obtained in 6 months.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/268. Posterior fossa epithelial cyst: case report and review of the literature.A 49-year old woman with progressive cranial nerve signs and hemiparesis was found at MR imaging and at surgery to have a cyst at the foramen magnum. immunohistochemistry and electron microscopy showed an epithelial cyst of endodermal origin. MR findings were of an extraaxial mass, with short T1 and T2 times. Unless immunohistochemistry and electron microscopy are used in the final diagnosis of such cysts, all posterior fossa cysts lined by a single layer of epithelium should be described simply as epithelial cysts.- - - - - - - - - - ranking = 0.11111111111111keywords = nerve (Clic here for more details about this article) |
3/268. Sacral nerve root cysts: A review on pathophysiology.Nerve root cysts of the sacral region are generally asymptomatic but are known to cause neurogenic claudication. In this paper we present an elderly lady who presented with claudication, whose MR imaging showed a sacral cyst. She underwent lumbo-sacral laminectomy, partial excision of the cyst wall with plication. A review of the possible pathophysiology of such a lesion is discussed.- - - - - - - - - - ranking = 0.44444444444444keywords = nerve (Clic here for more details about this article) |
4/268. Congenital intraorbital optic nerve cyst. Case report.Congenital cystic lesions of the optic nerve are exceedingly rare; only one case is reported in the world literature. The authors describe a case of congenital simple glial cyst in the intraorbital portion of the optic nerve with a brief review of the literature and comment on its histogenesis. A 45-day-old male infant was admitted to the hospital because of progressive proptosis and hypotropia in the left eye, which had been present since birth. magnetic resonance imaging of the left orbit revealed an ovoid, well-demarcated, homogeneous cystic mass in the intraconal retrobulbar area. The mass compressed the left eyeball with downward and lateral displacement. The wall of the cystic mass was very thin, and a needle puncture of the cyst released clear, colorless, watery fluid. The cystic wall was lined by loose astroglial nerve fibers with some scattered glial cells.- - - - - - - - - - ranking = 0.77777777777778keywords = nerve (Clic here for more details about this article) |
5/268. 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 = 0.11111111111111keywords = nerve (Clic here for more details about this article) |
6/268. 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 = 0.010751692631009keywords = organ (Clic here for more details about this article) |
7/268. A case of small cerebral cyst and pericentric inversion of chromosome 9 that developed schizophrenia-like psychosis.A case of schizophrenia-like psychosis (psychotic disorder not otherwise specified according to the DSM-IV criteria) with pericentric inversion on chromosome 9 [inv.(9) (p11; q13)] is reported. In this case, a minor brain anomaly, a small cyst in the left subcortex, was observed on magnetic resonance imaging of the brain. In the clinical course, prominent chronic hallucinations were observed; however, there was no evidence of the disorganization of personality, delusion, and deterioration in level of functioning that are usually seen in schizophrenia. This case and a review of the literature indicate that the pericentric region of chromosome 9 might be a potential areas of interest for the aetiology of psychiatric disorders. The phenotype-karyotype relationship of pericentric inversion on chromosome 9 and its relationship to psychosis are discussed.- - - - - - - - - - ranking = 0.010751692631009keywords = organ (Clic here for more details about this article) |
8/268. Case report: mucinous cholangiocarcinoma featuring a multicystic appearance and periportal collar in imaging.A case of mucinous cholangiocarcinoma (CC), a rare histological type of CC, featuring unusual images is reported. The patient was hospitalized because of acute development of jaundice and fever. Computed tomography demonstrated multiple cystic lesions in the liver and a band-like low density area parallel to the intrahepatic portal vein, a so-called 'periportal collar'. Endoscopic cholangiography revealed a stricture of the hepatic duct with slight upstream dilatation. Cytology of the bile juice and fine-needle aspiration of the cystic lesion in the liver disclosed mucinous carcinoma. The patient died of multiorgan failure 3 weeks after admission. The autopsied liver showed that multiple mucus lakes were lined with adenocarcinoma cells and signet ring cells were floating in the mucus lakes. The cancer cells had spread along the portal tract and invaded into the hepatic parenchyma.- - - - - - - - - - ranking = 0.010751692631009keywords = organ (Clic here for more details about this article) |
9/268. Transverse hepatectomy for symptomatic polycystic liver disease.Polycystic liver disease can result in massive enlargement of the liver with resultant debilitating symptoms of abdominal pain, chronic fatigue, and severely compromised functional status. Fenestration of hepatic cysts has been advocated as a treatment for polycystic disease. However, in patients with predominant small cyst replacement, fenestration alone often results in limited hepatic volume reduction without improvement in patient functional status. liver transplantation has also been previously advocated for polycystic liver disease with predominant small cyst replacement, but, with the severe shortage of donor organs, alternative treatment should be considered. In this report we present a case of massive enlargement of the liver with severe clinical debilitation due to polycystic liver disease. Transverse hepatectomy provided a safe and effective alternative to fenestration or liver transplantation.- - - - - - - - - - ranking = 0.010751692631009keywords = organ (Clic here for more details about this article) |
10/268. Maxillofacial hydatid cysts.We report 2 cases of hydatid cysts occurring in the submandibular gland and buccal submucosa, respectively. Our first case occurred in the submandibular salivary gland of a 20-year-old woman and the second involved the buccal submucosa of a 6-year-old boy. Both diagnoses were made after the excision of the lesions. Both patients were evaluated after surgery, and both were followed up, but no other organs were involved.- - - - - - - - - - ranking = 0.010751692631009keywords = organ (Clic here for more details about this article) |
