Abstract
Head and neck trauma-induced pulsatile tinnitus (PT) should be approached with caution, as it can rarely be attributed to an arteriovenous fistula (AVF). We present a 26-year-old male with a history of blunt trauma who presented delayed PT with direct AVF between the ascending pharyngeal artery (APA) and the internal jugular vein (IJV). The patient underwent occlusion of the fistula with transarterial embolization using coils and PT was completely resolved, confirming successful treatment. The delayed manifestation of PT in the APA-IJV fistula is probably due to the gradual formation of a pseudoaneurysm and subsequent AVF. This case highlights the importance of investigating PT in head trauma patients, as it can be a sign of AVF and possible complications. Overall, this case contributes to understanding delayed PT with AVF and emphasizes the importance of prompt diagnosis and treatment of AVF in patients with head and neck trauma.
