Abstract
Tinnitus is a common symptom with an incidence of 4-20%. Pulsatile tinnitus represents a minor subgroup of less than 10% of all patients suffering from tinnitus. Pulsatile tinnitus - different from permanent mostly idiopathic tinnitus is mainly caused by physical sources related to vascular pathologies resulting in a change in blood volume and pressure or an alteration of the vessel lumen. Differential diagnosis for pulsatile tinnitus include dural arteriovenous fistulas, glomus tumors of the jugular foramen and the middle ear or atherosclerotic diseases of the carotid artery in the petrous or cavernous segment. Anomalies of the dural sinuses and the jugular bulb have been described as rare sources of synchronized tinnitus. The Woven EndoBridge (WEB, Microvention, Tustin, CA) is an intraaneurysmal flow diverter for the treatment of broad-based arterial aneurysms with a high safety and effectiveness profile. The initial version of the WEB with a dual layer structure evolved to a single layer structure in two different versions (WEB SL, WEB SLS). The WEB system does not require a concomitant antiplatelet therapy compared to other intraluminal devices as extra-aneurysmal flow-diverters or intracranial stents. Here we describe a case of an aneurysmatic diverticulum of the jugular bulb in a patient with ipsilateral pulsatile tinnitus treated with a WEB device.
