Abstract
This article discusses the diagnosis, imaging workup, and management of a rare cause of pulsatile tinnitus: intraparotid arteriovenous malformation. A single patient with a superficial temporal arteriovenous malformation diagnosed by carotid duplex causing pulsatile tinnitus that failed initial surgical management. Repeat imaging failed to identify a cause for the persistent tinnitus. Reoperation with a parotid approach based on physical exam findings. Removal of a more proximal arteriovenous malformation in the parotid gland resulted in long-term resolution of the patient's pulsatile tinnitus. Physical examination is essential in the workup and management of pulsatile tinnitus. Imaging is a useful adjunct in the diagnosis of pulsatile tinnitus but should not be solely relied upon.
