A case of suprasellar germinoma with multiple remote metastases was reported including its autopsy findings. Several series of radiation therapy and prolonged steroid administration were considered to be causes of immunosuppression bringing about such metastases. A 29-year-old man had undergone a suprasellar germinoma removal and 5,200 rad of postoperative… (More)
We present the first reported cases of germinoma occurring in siblings of different genders. One tumor occurred in the left basal ganglia of a 7-year-old boy and the other in the suprasellar region of his 9-year-old sister. Both tumors were diagnosed as germinoma of two-cell pattern based on light and electron microscopic studies. Possible genetic factors… (More)
One of the greatest needs in the clinical bone field is a bioactive agent to stimulate bone formation. We previously reported that fibroblast growth factor-2 (FGF-2) exhibited strong anabolic actions on bone formation in models of rodents and dogs. Aiming at a clinical application, this study was undertaken to clarify the effect of a single local… (More)
One hundred and thirty-nine patients with cervical myelopathy who underwent anterior decompression surgery were reviewed to determine the characteristics and surgical outcome in 26 elderly patients over the age of 65. The mean age of the aged group was 69.7 and that of the remaining 113 patients was 50.0. Extensive spur removal and interbody fusion with… (More)
A rare case of a 14-year-old boy with a spontaneous (true) aneurysm of the superficial temporal artery is presented. The mass in the right parietal region was pulsatile and gradually enlarged in size for the last several months without any notable history of head trauma. The mass was successfully removed by surgery and has proved histopathologically to be a… (More)
A case of double teratomas located in the pineal region and the fourth ventricle is presented. A simultaneous occurrence from nonmetastatic, separate origins seems rare in cases of mature teratomas. Computerized tomographic scans led to detection of another asymptomatic teratoma. Surgical treatment produced good results.
A case of extradural nasal and orbital extension of a glioblastoma multiforme in the absence of previous surgical intervention is presented. Such penetration by a glioma is rare due to the natural resistance of the dura mater.
Aneurysms arising from the intracavernous portion of the internal carotid artery very rarely rupture. A patient is presented in whom rupture of an aneurysm wholly within the cavernous sinus caused a subarachnoid hemorrhage. The aneurysm was successfully clipped via a direct surgical approach. The possible mechanism by which subarachnoid hemorrhage occurred… (More)
Two cases of the diencephalic syndrome were reported with hormonal studies. The first case was initially admitted at her age of 4 years and 10 months old. Progressive visual disturbance and horizontal nystagmus had developed one year prior to the admission. Her weight gain had stopped since 10 months old. Partial removal of the hypothalamic pilocytic… (More)
Two cases of spontaneous pneumocephalus, which developed after ventriculoperitoneal shunt procedures for severe hydrocephalus caused by benign brain tumors, are reported. In both cases there was no previous history of cerebrospinal fluid leakage. Operation revealed that both patients had many small defects of the dura mater and the bone in the middle… (More)
