Pulsatile tinnitus is a rare but disabling symptom, which is frequently related to hemodynamic abnormalities within the temporal bone. Jugular diverticulum(JD), an outpouching of the jugular bulb is an extremely rare venous anomaly. According to the size and the location, it presents hearing loss, vertigo, and tinnitus that may be pulsatile. We present a case of right-side JD with pulsatile tinnitus, which is located laterally in the tympanic cavity and extends anteriorly close to tympanic orifice of Eustachian tube in an unusual manner of no interruption of the ossicular chain and no obliteration of the round window.
