Recent literature identifies venous etiologies as the most common cause of pulsatile tinnitus, including venous sinus stenosis, venous diverticula, and the less common enlarged mastoid emissary vein (MEV). Emissary veins are residual connections between the extracranial venous system of the head and the intracranial venous system.
