Abstract

Variability in the size of the dural sinuses and jugular bulb is not uncommon and usually manifests as a high jugular bulb encroaching upon the floor of the middle ear. A rarer entity is the superior and medial extension of the jugular bulb into the bone of the posterior wall of the internal auditory meatus. We report a case where this anomaly was encountered during acoustic neuroma surgery making exposure of the fundus of the internal auditory meatus technically impossible. The possibility of a communication with the superior petrosal sinus is discussed.
