Abstract
Microarteriovenous malformations (micro-AVMs) are a subgroup of brain AVM w ith a nidus diameter of less than 1 cm. Although many micro-AVMs may appear angiographically occult on cursory review, careful analysis will often rev eal a subtle diagnostic feature. Micro-AVMs present with intracranial hemor rhages that are generally large and associated with significant neurologic impairment. An awareness of these lesions as a possible source of hemorrhag e in a young person is critical. In general, micro-AVMs are eminently resec table lesions and patient outcome is determined primarily by the hemorrhage that brings them to medical attention.
