Intracranial arteriovenous malformations (AVMs) are a type of intracranial vascular malformation that consists of an abnormal connection of arteries and veins without intervening capillary beds. AVMs may come to medical attention because of seizure, intracranial hemorrhage, or incidental radiographic findings in a patient undergoing brain imaging for a different indication. This chapter focuses on the epidemiology, natural history, diagnosis, and management of intracranial AVMs.
