We present the case of a patient who developed pulsatile tinnitus that was found to be associated with petrous carotid aneurysm. The aneurysm successfully obliterated using stent-assisted coiling, after which symptom-free. Although aneurysms arising from segment internal artery are rare, this pathology must considered as causative factor in patients tinnitus. Endovascular treatment appears have been successful resolving symptoms pathology. Keywords: Pulsatile tinnitus, Aneurysm, Coil embolization
