title: Spontaneous bilateral dural arteriovenous fistulas with pulsatile tinnitus.
abstract: Pulsatile tinnitus with normal otoscopic findings often presents a diagnostic challenge to otolaryngologists and can be attributed to serious vascular malformations such as dural arteriovenous fistulas (DAVFs). Spontaneous DAVFs are relatively rare. A 65-year-old woman presented with sudden-onset subjective/objective pulsatile tinnitus on the right side that had persisted for 2 months. Angiography and magnetic resonance angiography revealed DAVF formation. Stereotactic radiosurgery was performed, and total remission of the DAVFs was achieved.
