Pulsatile tinnitus caused by an aneurysm of the transverse-sigmoid sinus: a new case report and review of literature

J Neuroradiol. 2012 Oct;39(4):276-9. doi: 10.1016/j.neurad.2012.02.001. Epub 2012 Sep 29.


A 28-year-old woman consulted for disabling pulsatile tinnitus. Clinical examination suggested a venous etiology. An aneurysm of the transverse-sigmoid sinus was identified on computed tomography angiography (CTA) and confirmed by digital subtraction angiography. Endovascular occlusion of the aneurysm with detachable coils permanently eliminated the bruit. Thus, this report is of a new case of pulsatile tinnitus caused by an aneurysm of the transverse-sigmoid sinus, with a focus on a literature review and etiopathophysiology. Embryological studies suggest that these aneurysms represent a partial remnant of the petrosquamous sinus.
