A rare case of ganglioglioma associated with intracerebral and intraventricular hemorrhage is reported. A 55-year-old male, who suddenly developed headache, nausca, left hemiparesis, and left hemihypesthesia, was admitted. Plain skull X-ray showed a floccular calcification in the right parieto-occipital region. Computed tomography scan disclosed a calcified mass lesion, not enhanced by the contrast medium, in the right parieto-occipital region, and associated with intracerebral and intraventricular hemorrhages. A right carotid angiogram revealed an avasular mass. A right parieto-occipital craniotomy, subtotal removal of the tumor, and evacuation of the hematoma were performed. The calcified area of the tumor was removed piece by piece, and a reddish soft tumor, not calcified, was found, infiltrating the wall of the right lateral ventricle and intraventricular space. Histologically, the tumor was composed of mature ganglion cells and glial cells. In the calcified area of the tumor, thin-walled angiomatous vessels and calcification in the thick wall of the vessels were observed. The postoperative course was uneventful except for left homonymous hemianopsia. The clinical aspects of ganglioglioma and the relation between this tumor and intracerebral hemorrhage arc discussed, reviewing the previously reported cases.
