A 63- year- old male consulted our clinic complaining of right pulsatile tinnitus. Pure tone audiometry demonstrated bilateral gradual sloping type of sensorineural hearing loss. Tinnitus was synchronized with cardiac pulsation and could be heard through an otoscope, recorded with a digital audio tape (DAT) recorder and analyzed with regard to frequency. The vascular murmur heard in his right temporal region suggested intracranial vascular disease and a neurosurgeon was consulted. Angiography demonstrated dural arteriovenous fistula between the inferior petrosal sinus and branches of the external carotid artery. After embolization of the fistula, objective pulsatile tinnitus disappeared. To date, the patient has been disease-free for 1 year.
Key words : pulsatile tinnitus, dural arteriovenous fistula, inferior petrosal sinus
