A 60-year-old house wife complained of anorexia, headaches and vomiting for several months. Later she developed disturbances in gait. At the terminal stage of her clinical course, 3 masses in the cerebrum and one in the cerebellum were detected by angiography and CT-scans. At autopsy, 3 masses in the frontal lobes, and one in each thalamus and still another in the cerebellum were found. They were accompanied with necrotic and haemorrhagic changes. Tumor cells were large irregular or round in shape, and showed metallophilia by the silver impregnations for reticlum cells and microglia. Some of them were multinucleated giant cells. Tumor cells showed occasionally phagocytic activity. Perivascular infiltration of tumor cells was marked around the tumor masses.
