title: Intracerebral hemorrhage from a metastatic brain tumor. Importance of differential diagnosis preceding stereotaxic hematoma aspiration.
abstract: Three cases of sudden intracerebral hemorrhage, which were diagnosed as hemorrhage from metastatic brain tumors following stereotaxic aspiration of a hematoma, are reported. Two cases had subcortical hemorrhage and one had cerebellar hemorrhage. Neither contrast-enhanced computed tomography scans nor angiograms revealed any findings other than those indicating the hematoma in all three cases. However, retrospective study of the anamnesis showed very mild symptoms due to metastasis to the brain or spinal cord in one case each. In cases of intracerebral hematoma located at atypical sites, extreme care is required for the differential diagnosis.
