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 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 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 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.
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.
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)
A 16-year-old boy who had undergone a ventriculoperitoneal (VP) shunt because of hydrocephalus at 8 years of age complained of pain around the right neck and chest. He concomitantly had a slight fever of unknown etiology, which had been lasting for several years. Skull and chest roentgenograms revealed an unusual calcified shadow around the shunt tube.… (More)
Six patients with dissection of the superior mesenteric artery (SMA) who were treated at our hospital between 1993 and 1999 were studied. Hypertension was considered significant as a risk factor. The clinical features were characterized by severe abdominal pain which radiated posteriorly, back pain, weak bowel sounds and exacerbation by eating. An… (More)
