Abstract:

Sigmoid sinus diverticulum is one of important reasons for causing pulsatile tinnitus. Although the incidence of pulsatile tinnitus caused by sigmoid sinus diverticulum is low, it can lead to serious symptoms requiring diagnosis and treatment in time. This reported patient developed continuous and pulsatile tinnitus at left side without any precipitating factors. The tinnitus was blowy-like with the same rate as heartbeat and disappeared when pressing the left jugular vein, which were typical symptoms of venous pulsatile tinnitus. The cerebral angiography suggested that there was a big and complex sigmoid sinus diverticulum at left side. The patient’s tinnitus symptom was improved remarkably after undergoing the endovascular interventional treatment with coil embolization. It indicated that interventional therapy can provide a new option for the treatment of venous sinus origin pulsatile tinnitus.

Key words: sigmoid sinus diverticulum, pulsatile tinnitus, interventional treatment, endovascular embolization, stenting, spring coil
