The jugular bulb is a confluence of the sigmoid and inferior petrosal sinuses within the posterolateral portion of the jugular fossa, continuing extracranially as the internal jugular vein. Its exact location within the temporal bone however is variable, and several jugular bulb abnormalities exist which can affect its position. Examples include a high-riding and/or dehiscent jugular bulb and a jugular bulb diverticulum. According to the literature, the prevalence of jugular bulb abnormalities is 10-15%, with dehiscence in 0.5-1.7% of individuals.
