Endovascular treatment of pulsatile tinnitus associated with transverse sigmoid sinus aneurysms and jugular bulb anomalies.

Pulsatile tinnitus of vascular origin may arise in arterial or venous structures. Many authors have reported the association of pulsatile tinnitus with anomalies of dural venous sinuses and the jugular bulb. In such circumstances, mainly concomitantly with disabling tinnitus, endovascular treatment has been successfully employed. We describe here a new case of jugular bulb diverticulum associated with transverse sigmoid sinus stenosis, in a patient presenting with disabling pulsatile tinnitus. She was treated with dural sinus stenting and selective embolization of the diverticulum. In addition, we performed a literature review aiming to identify possible risk factors for developing the symptoms, as well as the safety and results of endovascular treatment.
