Three-dimensional fast asymmetric spin echo (3D FASE) cisternography provides high spatial resolution and excellent contrast as a water image acquisition technique. It is also useful for the evaluation of various anatomical regions. This study investigated the usefulness and limitations of virtual endoscopic images obtained by 3D FASE MR cisternography in the preoperative evaluation of patients with neurovascular compression. The study included 12 patients with neurovascular compression: 10 with hemifacial spasm and two with trigeminal neuralgia. The diagnosis was surgically confirmed in all patients. The virtual endoscopic images obtained were judged to be of acceptable quality for interpretation in all cases. The areas of compression identified in preoperative diagnosis with virtual endoscopic images showed good agreement with those observed from surgery, except in one case in which the common trunk of the anterior inferior cerebellar artery and posterior inferior cerebellar artery (AICA-PICA) bifurcated near the root exit zone of the facial nerve. The veins are displayed in some cases but not in others. The main advantage of generating virtual endoscopic images is that such images can be used for surgical simulation, allowing the neurosurgeon to perform surgical procedures with greater confidence. 相似文献

PURPOSE: Rosai et al. published the World Health Organization (WHO) classification of thymic epithelial tumors in 1999, and its clinical usefulness seems to be established. It is our purpose to find the clinically relevant diagnostic points in the WHO Histological Classification of Thymoma. METHODS: Thymomas surgically removed from 100 consecutive patients at Juntendo University Hospital between October 1983 and February 2002 were classified according to the WHO histological classification. We assessed overall survival and recurrence-free rate calculated for each tumor type in the WHO classification compared with those of tumors classified by the Masaoka system. RESULTS: The thymic epithelial tumors in this series comprised 10 type A, 15 type AB, 18 type B1, 21 type B2, 33 type B3, and 3 type C tumors according to the WHO classification. Based on the Masaoka system, the disease was stage I in 53 patients, stage II in 30, stage III in 15, and stage IV in 2. The 15-year recurrence-free rate was 100% for type A, AB and B1, while the rates for types B2 and B3 were 66.7% and 54.5%, respectively. The 10-year recurrence-free rate was 66.7% for type C. The 15-year recurrence-free rate of the 64 patients with type A, AB, B1, and B2 thymomas was significantly higher from that of the 33 patients with type B3 thymoma (p=0.0026). CONCLUSION: When using the WHO classification, it is critical to distinguish type B3 thymoma from other tumor types. 相似文献

We report a case of aspergilloma in an 80-year-old male patient who had no identifiable underlying disease before surgery for pneumothorax. He was hospitalized for left pneumothorax. A chest CT revealed a large bulla in the left lung apex with a nodule (diameter; 1.5 cm) at the edge of the bulla. After thoracodocesis, air leakage persisted and a large bulla and nodule were resected. Aspergillus was detected histopathologically in the nodule. Treatment with itraconazole 200 mg a day followed, and 4 months later he had no recurrent pneumothorax or Aspergillus infection. 相似文献

Introduction The authors report a case of interhemispheric ependymal cyst accompanied with agenesis of the corpus callosum in a fetus.
Discussion Routine ultrasound and subsequent magnetic resonance imaging of a 20-year-old woman at 33 weeks and 1 day of gestation detected
a large interhemispheric cystic lesion in the fetal cranial cavity. Caesarian section was carried out at 36 weeks because
of the progressive enlargement of the fetal head. The cyst was multiloculated and a cyst peritoneal shunt placement resulted
in collapse of the drained cyst components followed by enlargement of others. After wrack-a-mole-like shunt revisions, open
surgery was performed at the age of 2 years. Cyst walls were fenestrated and the cavities were communicated with each other
and eventually with the lateral ventricle. Pathological diagnosis of the cyst wall was ependymal cyst. The boy is now 3 years
old, and growing without apparent developmental delay or recurrence. Current concept and management policy of the interhemispheric
cyst accompanied with agenesis of the corpus callosum is reviewed. 相似文献

Use of laboratory data to identify risk factors of giant coronary aneurysms due to Kawasaki disease 总被引:5,自引:0,他引:5

BACKGROUND: Although some laboratory findings are known to be indicators of the risk of giant coronary aneurysm formation among Kawasaki disease patients, an appropriate cut-off point to predict aneurysm formation is not clear. METHODS: One hundred and five patients with giant coronary aneurysms were selected from the 15th and 16th nationwide surveys of Kawasaki disease in Japan. A total of 2936 patients without Kawasaki disease were recruited from a single hospital as a control group. Odds ratios were calculated for six laboratory data with specific values as cut-off points. Receiver operating characteristic (ROC) curves were observed to determine the most appropriate laboratory tests and cut-off points. RESULTS: Hematocrit, leukocyte count, neutrophil proportion, and hemoglobin had one or more peaks of odds ratio for specific cut-off points, but they did not have a clear cut-off point for the predictor according to the receiver operating characteristic curves. Alanine aminotransferase (ALT) increased the risk of giant coronary aneurysms continuously so no clearly appropriate cut-off point was identified. Serum sodium concentration of 135 mEq/L had a peak of odds ratio, and those with <135 mEq/L had the highest odds ratio (4.78). This value seemed appropriate with a sensitivity of 78% and specificity of 57%, although the predictive positive value was as small as 5%. CONCLUSION: The author's propose that a serum sodium concentration of <135 mEq/L at the patient's first visit to hospital may be a predictor of giant coronary aneurysms due to Kawasaki disease. 相似文献

The female patient was diagnosed as having Von Gierke's disease at 14 years of age, based on clinical manifestations, laboratory examination and liver biopsy. At 19 years of age she had uremia and died from its deterioration at 24 years of age. The parents were consanguineous, and a 27-year-old sister is presently hospitalized for renal Insufficiency with hepatomegaly. On autopsy, the patient's kidneys were highly contracted and contained a number of small cysts, mainly in the medulla. Histological examination indicated periglomerular fibrosis, glomerular hyalinization, tubular atrophy or cystic dilatation and intersitial fibrosis with round cell infiltration. These findings correspond to Fanconi's familial juvenile nephronophthlsis, except for age. The liver was markedly enlarged and Indicated severe glycogen deposits, but the kidney did not contain glycogen deposits. It can, therefore, be presumed that the renal lesions were not a secondary consequence of long-term glycogen deposits but that renal and hepatic lesions were associated with each other. 相似文献

A case of malignant Brenner tumor with peritoneal metastasis in a 67-year-old woman was reported. The multilocular cystic tumor of right ovary was 420 g in weight, and their cystic walls were covered with multilayered tumor cells showing papillary pattern very frequently. The tumor was histologically transitional cell carcinoma with occasional glandular structures but no squamous differentiation corresponding to grade 2 or 3 urinary bladder carcinoma. The pattern of benign Brenner tumor was not identified, but there was some area of proliferating Brenner tumor. Immunohistochemically, carcinoembryonic antigen was detected in several tumor cells, especially in the intercellular spaces among them, and cytokeratin was detected only in some tumor cells. Ultrastructurally, the malignant Brenner tumor shared many common features with the benign one and also bladder tumor. Intercellular spaces with microvilli were frequently found and thought to be important for diagnosis. The morphologic criteria of this rare tumor are discussed. 相似文献

We present a case of pre-elastofibroma-like lesion, a kind of elastic-producing fibrous tumor. The small colonic polyp, which was found in a 49-year-old asymptomatic man in association with a large colonic adenoma, showed submucosal nodular deposits of fine granular or fibrillar eosinophilic materials with interspersed fibroblastic cells. Elastic stain revealed these deposits to consist mainly of dark gray granular or partially fibrillar dense elastinophilic materials, most of which were digested with elastase. This stromal lesion somewhat resembled a pre-elastofibroma. Therefore, pre-elastofibroma-like lesions should be kept in mind as a possible origin of colonic polyp. 相似文献
