title: Angiographically occult cerebral vascular malformations with abnormal computed tomography.
abstract: Two cases of histologically proven cerebrovascular malformation were detected by computed tomography (CT) scanning but not by cerebral angiography. One of the patients had a cavernous angioma and the other an arteriovenous malformation. Caution is advised in assuming that angiographically avascular lesions demonstrable by CT scanning are not vascular malformations.
