  • Look Inside

 We report a rare case of aberrant internal carotid artery in the middle ear. The patient was a 30-year-old man with pulsatile tinnitus. MRA and 3D-CTA revealed an aberrant course of the internal carotid artery in the middle ear.

 3D-CTA proved useful for radiographic diagnosis, leading to the observation of an aberrant internal carotid artery passing the foramen.

 We discuss the diagnosis and management of such patients.
