title: [Glioblastoma and fibrosarcoma in the brain with metaplastic bone formation--a case report].
abstract: The authors report a case in which left deep temporal fibrosarcoma with calcified area developed about 6 months after radiation therapy for left temporal astrocytoma. A 37 year-old woman was admitted to our clinic because of headache and visual deterioration. CT scan and angiography suggested left deep temporal glioma and on August 5, 1980, partial resection was performed. Histological sections showed astrocytoma G 2. Postoperative course was uneventful and she left the hospital after radiation therapy of 50 Gy. On March, 1981, right hemiparesis was noticed and progressed rapidly. CT scan suggested left temporal tumor recurred. On March 30, 1981, second operation was performed and this time, histological sections showed glioblastoma. After operation, beta-Interferon (IFN) was given intratumorally via Ommaya's reservoir (3 X 10(6) IU, daily). But in spite of IFN therapy, tumor became larger and she died on June 30, 1981. Autopsy revealed coexistence of glioblastoma and fibrosarcoma with metaplastic bone formation. A brief discussion concerning the problem of cerebral mixed tumors follows the description of the case.
