A 6-year-old male with bilateral lenticulostriate arteriovenous malformations (AVMs) had suffered an intraventricular hemorrhage at the age of 10 days. Transfemoral cerebral angiography performed 6 years later revealed bilateral AVMs at the basal ganglia accompanied by vascular anomalies. Both AVMs appeared inoperable, and were treated conservatively. Bilateral, symmetrical cerebral AVMs are extremely rare, only three such cases having been reported.
