N2 - Atypical arteriovenous fistulas (AVFs) lack the parenchymal nidus observed in arteriovenous malformations (AVMs) and are not dural-based lesions supplied by meningeal arteries, unlike true dural AVFs. Atypical AVFs are parenchymally based with a nondural arterial supply. This video presents a man in his 50s with a remote carotid takedown for flow reduction of a described temporal AVM. Imaging showed a basal temporal AVF supplied by middle cerebral artery branches, coalescence of arterial feeders onto a large venous varix, and no intervening nidus. Dearterialization of the venous varix eliminated the shunting lesion. Atypical AVFs are often misdiagnosed but can be cured with microsurgical interruption.
