Abstract
Cerebellar hemangioblastomas were seen in seven persons, five being members of the same family. All were studied with constrast enhanced CT scans and vertebral angiograms. The CT scans were superior for demonstrating the cystic component of the tumors and associated hydrocephalus, features not usually evident on the angiograms. The angiograms were superior for revealing the vascular nature, supply and drainage of the tumors. In several patients the angiograms revealed more tumors than could be seen by CT. Both CT and angiography contribute important information in the diagnosis of these neoplasms.
