1/272. Bilateral renal masses after local bacillus Calmette-Guerin therapy for postcystectomy ureteral cancer.bacillus Calmette-Guerin was administered through the ileal conduit of a 63-year-old man with upper tract recurrence of transitional cell carcinoma. Subsequent computed tomography showed bilateral renal masses, which were granulomatous at pathologic examination. The bacilli likely reached the kidneys via proven ileoureteral reflux. patients with reflux may benefit from antituberculous prophylaxis.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
2/272. Solitary sarcoid granuloma of the cerebellopontine angle: a case report.BACKGROUND: sarcoidosis involves the nervous system about 5% of the time and usually manifests as a granulomatous inflammation of the basal meninges and hypothalamus. Cases which are strictly isolated to the central nervous system occur infrequently; rarely, they may present as an intracranial mass. methods: We present the case of a solitary sarcoid granuloma at the cerebellopontine angle in a 42-year-old female who presented with headache, facial numbness, and hearing loss. RESULTS: A suboccipital craniectomy was performed and the lesion was noted to be grossly adherent to the lower cranial nerves and skull base. The lesion was misdiagnosed as a meningioma with preoperative magnetic resonance imaging and intraoperative histology, and perhaps additional morbidity resulted. CONCLUSION: We present this case in order to demonstrate the importance of differentiating these dural-based lesions and propose that cases of neurosarcoidosis presenting as a solitary granuloma be treated with surgical debulking and immunosuppression.- - - - - - - - - - ranking = 2.6573411227045keywords = central nervous system, nervous system (Clic here for more details about this article) |
3/272. diagnosis and physiopathology of laryngeal deposits in autoimmune disease.We report the clinical features and pathology of a previously unreported form of vocal fold disease seen in 4 patients, 3 of whom were diagnosed as autoimmune disease. The characteristic features of these lesions were found as bilateral transverse lesions in the mid portion of the vocal folds. The patients had dysphonia and diplophonia. Stroboscopic examinations showed 180-degree phase shifts between the anterior and posterior portion of the vocal folds. Case 1 had systemic lupus erythematosus, case 2 had Hashimoto's thyroiditis, and case 3 had progressive systemic sclerosis. Prior to the onset of hoarseness, autoimmune antibody titers were increased. These cases need differential diagnosis from vocal fold nodules and cysts. Two cases were recurrent after endoscopic surgery, 1 recurring 3 times. Glucocorticoid was effective in preventing the recurrence in the early phase. recurrence may have occurred because the surgical strategy was the same as that used for vocal fold nodules or cysts.- - - - - - - - - - ranking = 0.5keywords = cyst (Clic here for more details about this article) |
4/272. Gastric cancer with sarcoid reactions in the regional lymph nodes, the stomach wall, and the splenic parenchyma: report of a case.A 66-year-old man was referred to our institute for investigation of heartburn and epigastralgia. Endoscopic examination demonstrated a type 4' gastric cancer which occupied the whole stomach. At laparotomy, multiple small nodules were found in the spleen which were diagnosed as metastases of the gastric cancer. Thus, total gastrectomy with distal pancreatectomy, splenectomy, cholecystectomy, and left adrenalectomy, combined with D4 lymph node dissection, was performed. Microscopic examination of the tumor revealed tubular and mucinous adenocarcinoma which invaded the muscularis propria. Sarcoid reactions were observed in the submucosa adjacent to the carcinoma tissue. Only one lymph node from station no. 8a demonstrated tumor metastasis, while those from station nos. 1, 2, 7, 8, 9, 10, 11, 13, and 16 revealed sarcoid reactions without tumor metastases. Subsequently, the multiple small nodules that had been presumed to be splenic metastases at laparotomy were found to be sarcoid reactions similar to those seen in the submucosa and regional lymph nodes. Since no skin or ocular lesions indicative of systemic sarcoidosis were seen in this patient, a diagnosis of advanced gastric cancer associated with sarcoid reactions was established. To our knowledge, there have been no previous reports regarding an association between sarcoid reactions in the spleen and gastric cancer.- - - - - - - - - - ranking = 0.25keywords = cyst (Clic here for more details about this article) |
5/272. Endoscopic sonography in the diagnosis of xanthogranulomatous cholecystitis.Xanthogranulomatous cholecystitis (XGC) is an unusual inflammatory disease of the gallbladder that may simulate gallbladder cancer. We report the findings with conventional sonography, endoscopic sonography (EUS), and CT in 3 cases of XGC. EUS could visualize hyperechoic nodules in the gallbladder wall, probably representing xanthogranulomas, but loss of the multilayered structure of the gallbladder wall and infiltration into adjacent organs make differentiating XGC from gallbladder cancer difficult with EUS alone.- - - - - - - - - - ranking = 1.25keywords = cyst (Clic here for more details about this article) |

7/272. Xanthogranulomatous oophoritis--a case report.This is a case of a 25 year old unmarried women who presented with intermittent fever and lower abdominal pain. laparotomy revealed a large cystic left sided tuboovarian mass adherent to surrounding structures and containing foul smelling fluid. microscopy showed extensive replacement of the ovary by a chronic inflammatory exudate composed predominantly of foamy macrophages.- - - - - - - - - - ranking = 0.25keywords = cyst (Clic here for more details about this article) |
8/272. Symptomatic Rathke's cleft cyst coexisting with central diabetes insipidus and hypophysitis: case report.We describe a 48-year-old female with acute onset of central diabetes insipidus followed by mild anterior pituitary dysfunction. magnetic resonance imaging (MRI) revealed enlargement of the hypophysis-infundibulum accompanied by a cystic component. She underwent a transsphenoidal exploration of the sella turcica. Histological examination showed foreign body type xanthogranulomatous inflammation in the neurohypophysis which might have been caused by rupture of a Rathke's cleft cyst. The MRI abnormalities and anterior pituitary dysfunction improved after a short course of corticosteroid administration, but the diabetes insipidus persisted. The histological findings in this case indicated the site of RCC rupture and the direction of the progression of RCC induced neurohypophysitis and adenohypophysitis.- - - - - - - - - - ranking = 6.7802751097151keywords = cleft cyst, cyst, cleft (Clic here for more details about this article) |
9/272. 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 = 1.5keywords = cyst (Clic here for more details about this article) |
10/272. Fibro-osseous lesions of the central nervous system: report of four cases and literature review.Fibro-osseous lesions, also reported as calcifying pseudoneoplasms of the neural axis, are uncommon lesions of the CNS. We report four additional cases: two extraaxial and two intraaxial, in patients ages 33, 47, 49, and 59 years at presentation. Fibro-osseous lesions involving the CNS demonstrate variable proportions of fibrous stroma, bone, palisading spindle to epithelioid to multinucleated cells in association with a highly distinctive, perhaps pathognomonic, chondromyxoid-like matrix often distributed in a nodular pattern. This histopathologically distinctive lesion can be seen in many regions of the neuraxis, often with a dural association, and most commonly along the vertebral column. It appears to be a slow-growing lesion and, with wide excision, the prognosis is excellent. The etiology remains unclear, but the preponderance of data favors a reactive rather than neoplastic process. If this putative pseudotumor is not recognized histopathologically, a neoplastic or infectious differential might result in inappropriate investigations and potentially harmful therapies.- - - - - - - - - - ranking = 8.1729239818602keywords = central nervous system, nervous system (Clic here for more details about this article) |
