Abstract

Jugular bulb diverticulum (JBD) is a rarely reported vascular anomaly, which is an extraluminal outpouching from the jugular bulb. Especially, there exists a lack of reported cases involving JBD encroaching the internal auditory canal (IAC) in Korea. Subjects with JBD may be asymptomatic or have variable symptoms based on its location and size. In this article, we report a unique case of JBD eroding into the IAC that was presented as sudden sensorineural hearing loss with vertigo.
