Angiographically occult cerebral vascular malformations with abnormal computed tomography.
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.
