A Case of Dural Arteriovenous Fistula in a Patient Presenting with Objective Tinnitus

A 42-year-old woman presented with a chief complaint of worsening tinnitus in the left ear. The tinnitus was very low in volume, and audiometry and tympanometry findings were normal. One month later, her condition had worsened to the extent that a stethoscope placed at the temporal region or entrance of the external auditory meatus revealed objective pulsatile tinnitus, indicating vascular murmur. Findings from magnetic resonance imaging suggested intracranial vascular lesions. Dural arteriovenous fistula was diagnosed on the basis of angiography findings. Tinnitus resolved after arterial embolization. At present, there are no signs of recurrence or postoperative complications. The present findings indicate that vascular murmur should be diagnosed and treated with caution.
