Combined cavernous-arteriovenous malformation

Cerebral angiomas consisting of two distinct types of malformations are rare. A case of combined arteriovenous and cavernous angioma is reported. For what is believed to be the first time, the cavernous portion of the angioma was clearly demonstrated by angiography and appeared similar to cavernous malformations occurring outside the central nervous system. This case emphasizes the continuous overlapping spectrum of cerebral vasculature anomalies.
