Development of multiple cerebral arteriovenous malformations documented in an adult by serial angiography. Case report.

Abstract

A 50-year-old woman with a parietal intracerebral hematoma was initially treated by hematoma evacuation. Initial preoperative and follow-up angiograms obtained 6 months later demonstrated no pial arteriovenous malformations (AVMs). She suffered a subarachnoid hemorrhage 8 years later. Results of follow-up cerebral angiography revealed the development of previously undetected multiple cerebral AVMs. This appears to be the first reported case of the development of multiple cerebral AVMs in an adult, demonstrated on serial angiography.
