Arteriovenous malformations (AVMs) are tangled anastomoses of blood vessels in which arteriovenous shunting occurs in a central nidus (the area where feeding arteries converge and from which enlarged veins drain) [1, 2]. AVMs are the most common type of vascular malformation, with autopsy data suggesting an overall frequency of about 1-4% [3]. However, only about 12% of AVMs become symptomatic [1]. The mean age at presentation is 35 years old, and the majority present with intracranial hemorrhage (usually intracerebral hemorrhage) [1, 4]. There is an overall risk of initial hemorrhage of about 2-4% per year. The next most common presentation is seizure, followed by headache and focal neurological deficit [1]. In young children, presentation can also include congestive heart failure and hydrocephalus [3].
