Pulsatile Tinnitus as the Sole Manifestation of an Internal Carotid Artery Aneurysm Successfully Treated by Coil Embolization

ABSTRACT

Pulsatile tinnitus is tinnitus that coincides with the patient's heartbeat. It constitutes a small portion of all tinnitus, but it is often the first or sole manifestation of a serious disease in the nervous system. Aneurysm of the internal carotid artery is known as a rare cause of pulsatile tinnitus and, in the main, aneurysms of the petrous portion have been reported as a cause of pulsatile tinnitus. We present an interesting case of pulsatile tinnitus that was caused by a paraclinoid aneurysm in this report and discuss clinical features and treatment of paraclinoid aneurysm.
