1/28. 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 = 1keywords = cyst (Clic here for more details about this article) |
2/28. Biliary cystadenoma: rare variant of intrahepatic cystic disease.Intrahepatic nonparasitic cystic disease is rare and may be of congenital or neoplastic origin. The most frequent symptoms and signs are nonspecific and include pain, nausea, fullness, increased girth, and palpable mass. Interventional therapy is reserved for symptomatic patients, which usually corresponds to cysts >5 cm in diameter. Retrospective analysis revealed 26 cases of intrahepatic cystic disease over 15 years at our institution. We discuss the case of a patient who had bilobular biliary cystadenomatous disease, a rare, benign variant of intrahepatic nonparasitic cystic disease.- - - - - - - - - - ranking = 0.86666666666667keywords = cyst (Clic here for more details about this article) |
3/28. gallbladder vasculitis associated with type-1 cryoglobulinemia.A patient with type I cryoglobulinemia and monoclonal gammopathy of uncertain significance was found to have acute gallbladder vasculitis. The most prominent manifestation was upper abdominal pain in the setting of normal liver tests. An abdominal ultrasound demonstrated a thickened gallbladder wall, along with gallstones. HIDA scanning showed a nonfunctioning gallbladder with an edematous and thickened wall. There was characteristic leukocytoclastic vasculitis affecting the gallbladder. The patient recovered uneventfully subsequent to cholecystectomy. gallbladder vasculitis should be considered in patients with unexplained upper abdominal pain and systemic vasculitis.- - - - - - - - - - ranking = 0.066666666666667keywords = cyst (Clic here for more details about this article) |
4/28. Supratentorial leptomeningeal metastasis of a medulloblastoma without cerebellar tumor recurrence.The authors report on a 15-year-old girl presenting with headache and nausea. Cranial magnetic resonance imaging (MRI) showed a diffuse leptomeningeal contrast enhancement 5 years after resection of a posterior fossa medulloblastoma followed by radio- and chemotherapy. A left frontal biopsy revealed tumor spread. Histopathological findings of the tumor were identical to those obtained from the original medulloblastoma. To the authors' knowledge this is the first report of late supratentorial leptomeningeal metastasis from a medulloblastoma while no local recurrence or spinal leptomeningeal dissemination had occurred.- - - - - - - - - - ranking = 5.2049172665622keywords = leptomeningeal (Clic here for more details about this article) |
5/28. Intractable vomiting from glioblastoma metastatic to the fourth ventricle: three case studies.Dissemination of malignant glioma to the fourth ventricle with metastatic deposits and intractable vomiting is rare. Leptomeningeal extension of malignant glioma is an uncommon condition that has been reported in patients with end-stage disease and is usually unresponsive to any treatment modality. We describe 3 patients with progressing recurrent glioblastoma multiforme in whom leptomeningeal invasion manifested itself as intractable vomiting due to tumor metastases in the floor of the fourth ventricle. All patients received additional radiation therapy focused to the posterior fossa, with complete resolution of vomiting occurring within 10 days after irradiation. The remission of symptoms in these patients persisted until their death 3-4 months after the repeat radiation therapy. These reports indicate that additional focused radiation should be considered because of its significant therapeutic effect in alleviating intractable nausea and vomiting in patients with glioma metastasized to the posterior fossa.- - - - - - - - - - ranking = 0.74355960950889keywords = leptomeningeal (Clic here for more details about this article) |
6/28. Gallstone ileus as a complication of cholecystolithiasis.biliary fistula and gallston ileus are rarely found. The diagnosis is difficult. Gallstone ileus requires urgent and appropriate surgical therapy. Enterolitotomy remains the gold standard of operative treatment for gallstone ileus, but additional procedures of one-stage cholecystectomy and repair of fistula are necessary. Some researchers advise first to resolve the gallstone ileus and then to perform the elective operation for gallstone disease in more ideal circumstances. Our case had clinical evidence of ileus, which was confirmed by radiological exam. Ultrasonographic examination performed before operation did not confirm the presence of gallbladder; it did not detect a large stone located in the intestine. The patient, a 75-year-old woman, was operated on. During the procedure it was shown that the second part of the duodenum was involved in a scar and displaced to the hepatic hilus. There was no gallbladder; it was probably destroyed by a long-lasting vesicoduodenal fistula. cholangiography also did not detect the gallbladder. Biliary passage through the common bile duct was sufficient. The hole in the duodenum wall was sutured, and Kehr drain was inserted into the common bile duct. The gallstone was removed by incision of the intestine down to the obstruction. The postoperative period was complicated by a small suppuration of the laparotomy wound. Vesicoduodenal fistula present for a long time can lead to atrophy of the gallbladder. The one-stage procedure seems to be appropriate if biliary fistula and gallstone ileus are found.- - - - - - - - - - ranking = 0.33333333333333keywords = cyst (Clic here for more details about this article) |
7/28. Non-aneurysmal primary subarachnoid hemorrhage in pregnancy-induced hypertension and eclampsia.Clinical as well as neuroimaging studies of women with eclampsia or pregnancy-induced hypertension (PIH) have described a variety of neurologic manifestations, including intraparenchymal brain hemorrhage. autopsy studies have described pia-arachnoid hemorrhage in women who died of eclampsia, but radiographic studies have found only intraparenchymal hemorrhage. The author describes clinical and radiographic features in three women with subarachnoid hemorrhage associated with PIH.- - - - - - - - - - ranking = 9.1444225796155keywords = arachnoid (Clic here for more details about this article) |
8/28. An unusual presentation of Nelson's syndrome with apoplexy and subarachnoid hemorrhage.A thirty-eight year-old lady with a history of bilateral adrenalectomy for Cushing's disease seven years previously, presented with sudden onset of severe headache, nausea, vomiting and loss of consciousness. She was somnolent and confused. She had neck stiffness, sixth nerve palsy and mydriasis on the left side. Computerized tomography (CT) and magnetic resonance imaging (MRI) studies revealed a non-homogeneous, grade IV D pituitary mass lesion associated with hemorrhage in the chiasmatic, interhemispheric, cerebellopontine, perimesencephalic cisterns and a hematoma within the frontal lobe. Angiography showed only bilateral elevation of horizontal segments of the anterior cerebral arteries. According to this angiographic evidence, it was presumed that the subarachnoid hemorrhage and the intracerebral hematoma were linked to pituitary adenoma apoplexy. ACTH level was 450 pg/ml. The hemorrhagic lesion with suprasellar extension was totally removed by left pterional craniotomy. Histological examination revealed a necrotic, acth-secreting pituitary adenoma. Even though apoplexy is a well known complication of pituitary adenomas, to our knowledge subarachnoid hemorrhage and intracerebral hematoma as a result of pituitary apoplexy in the context of Nelson's syndrome has not previously been reported.- - - - - - - - - - ranking = 9.1444225796155keywords = arachnoid (Clic here for more details about this article) |
9/28. Spontaneous retroperitoneal hemorrhage localized by blood pool scintigraphy.A healthy 17-year-old girl presented to the emergency department with a 1-day history of left upper quadrant abdominal pain associated with nausea and vomiting. Her hematocrit was 22. On physical examination, she had left upper quadrant fullness and tenderness. Initial computed tomography revealed a large, loculated, left-sided retroperitoneal hematoma. blood pool scintigraphy with labeled red cells revealed a very large photon-deficient area with 3 areas of active bleeding in the upper margin of the cold area. An angiogram showed active extravasation from the left inferior phrenic artery. The patient was felt to have had spontaneous adrenal hemorrhage, likely within a preexisting, large adrenal cyst. Spontaneous hemorrhage into an adrenal cyst is a rare entity that can be life-threatening if not treated early in its course.- - - - - - - - - - ranking = 0.13333333333333keywords = cyst (Clic here for more details about this article) |
10/28. Multiple eccrine hidrocystomas.The clinical and pathological features and treatment of two patients with multiple eccrine hidrocystomas are presented. The first case is characterized by multiple pearly papules with a bluish hue located in the periorbital region and the bridge of the nose. The second case is characterized by multiple, skin-coloured papules located in the periorbital area, forehead, chin and nose. Both were exacerbated by a hot and humid environment. Histopathologically, both demonstrated a unilocular cyst located in the dermis, with a 2-3-layer wall composed of cuboidal epithelium that was non-keratinizing. Treatment with topical atropine sulphate 1% in aqueous solution three times a day was instituted in the first case; however, this was poorly tolerated because of blurred vision and nausea. The lesions were subsequently hyfrecated with a good response. The second case was treated with topical atropine sulphate 1% in aqueous solution three times a day with a good response.- - - - - - - - - - ranking = 0.4keywords = cyst (Clic here for more details about this article) |
