A Case of Jugular Bulb Diverticulum Accompanied with Pulsatile Tinnitus / 대한이비인후과학회지

ABSTRACT

Pulsatile tinnitus is perceived as sounds that vary in frequency, intensity and duration. It is also characterised by its unique feature of rhythmicity that is synchronous with the human pulse. Clinically, it is a serious disorder because it is associated with other life threatening or curable diseases. Pulsatile tinnitus may originate from several sites including the arterial, arteriovenous, venous vessels and the myoclonus. Jugular bulb diverticulum, one of the causes of venous pulsatile tinnitus, is observed as a protrusion of the jugular vein lumen with a waist like margin. It may extend either laterally in the tympanic cavity or medially towards the petrous pyramid close to the inner ear. This leads to pulsatile tinnitus, sensorineural or conductive hearing loss and vertigo. In this paper we report a recent case in which we confirmed jugular bulb diverticulum in a 59 years-old woman whose complaint of pulsatile tinnitus was spontaneously disappeared during the follow up.
