The authors analyzed 153 cases of histologically verified intracranial germ cell tumors. The histological diagnosis was germinoma in 63 patients (41.2%), teratoma in 30 (19.6%), and other types of tumors in 60 patients (39.2%). The patients were treated by a consistent policy of surgical removal with histological verification followed by radiation therapy(More)
Brain atrophy with mental and neurologic deterioration developing a few months after radiation therapy in patients without residual or recurrent brain tumors has been recognized. Two illustrative case reports of this pathologic entity are presented. Six autopsy cases with this entity including the two cases were reviewed neurologically, radiographically,(More)
Central neurocytoma is considered to be a benign intracranial neoplasm, but little is known about the biological behavior of this type of tumor.Proliferative activity of central neurocytoma was measured in 10 cases using MIB-1 staining for Ki-67 antigen.The MIB-1 staining value varied from < 0.1% to 5.6%, to indicating that some of these tumors have(More)
We analyzed our treatment results in 153 patients with histologically verified intracranial germ cell tumors and proposed classifying them into three therapeutic groups with good prognosis, intermediate prognosis, and poor prognosis. In this work, we selected patients treated with chemotherapy (cisplatin or carboplatin combinations) in each subgroup, and we(More)
The computed tomographic (CT) and magnetic resonance imaging (MRI) features of 73 histologically proven primary intracranial germ cell tumors were analysed. CT images were available for all 73 patients, and 22 of them were also examined by MRI. The tumors were classified as germinoma, mature teratoma, immature or malignant teratoma, yolk sac tumor,(More)
Two hundred and twenty-one cases of IC dorsal aneurysm (ICDA) with subarachnoid hemorrhage (SAH) from 365 cases in the nationwide surveillance of ICDA (NSICDA) data bank were studied with special reference to the dissecting type. Dissection of the internal carotid artery (ICA) was confirmed in 50 out of 221 SAH cases. In 193 surgically treated cases, 40(More)

On the surgery of glioblastoma multiforme, most cases are beyond the scope for desirable removal of tumors. The restriction of the surgical treatment has inevitably required postoperative radiation therapy. Although patients treated with postoperative radiation therapy showed significantly extended survival rates as compared to those receiving surgical(More)
