Abstract
A case of a successfully removed glioma at the base of the IVth ventricle was reported. The patient was a 43-year-old woman who had complained of gait and visual disturbances four years before admission. Plain and enhanced CT showed remarkable hydrocephalus, dilatation of Sylvian aqueduct, and deformity of the IVth ventricle. An exploratory craniotomy was performed and the tumor, 25×15×7 mm in size, was found at the base of the IVth ventricle and was macroscopically totally removed. Histological diagnosis was fibrillary astrocytoma. Post-operative course was favorable. Symptoms, diagnosis, and operation of the tumor were discussed.
