An unusual vascular abnormality, usually on the right temporal bone, and commonly asymptomatic. Positioning of a jugular bulb diverticulum can produce symptoms of conductive hearing loss, pulsatile tinnitus, and vertigo. Other signs and symptoms include sensorineural hearing loss, facial palsy, and headache. Diagnosis is made with MR angiography.

Management of symptomatic high jugular bulb includes observation or surgery, with favorable prognosis.
