====== Cerebellar Arteriovenous Malformation Epidemiology ====== [[Cerebellar arteriovenous malformation]]s (AVMs) comprise 10%–15% of all [[intracranial arteriovenous malformation]]s ((Arnaout OM, Gross BA, Eddleman CS, Bendok BR, Getch CC, Batjer HH. Posterior fossa arteriovenous malformations. Neurosurg Focus. 2009;26(5):E12.)). and this relatively low incidence has led authors to combine them with [[brainstem arteriovenous malformation]] in reports on infratentorial or [[posterior fossa arteriovenous malformation]]s ((Batjer H, Samson D. Arteriovenous malformations of the posterior fossa: clinical presentation, diagnostic evaluation and surgical treatment. Neurosurg Rev. 1986;9:287–296.))
