The value of CT venography in the diagnosis of jugular bulb diverticulum: A series of 3 cases

Jugular bulb diverticulum is a rare diagnosis, as fewer than 50 cases have been reported in the literature. It has been reported that unilateral auditory symptoms may accompany this entity, although some patients are asymptomatic. We present a case series of 3 patients who were referred to our tertiary care neurotology center with a unilateral jugular bulb diverticulum along with unilateral sensorineural hearing loss and tinnitus. These patients were evaluated clinically and radiographically. This case series (1) adds further documentation of the presence of unilateral auditory symptoms in patients with a jugular bulb diverticulum and (2) demonstrates the value of computed tomographic venography in the diagnosis of jugular bulb diverticulum.
