Abstract

The position and dimensions of the jugular bulb and the venous dural sinuses vary considerably. While the anatomical variations of the jugular bulb have been extensively reported in the literature, that of the sigmoid sinus have been reported only rarely. We report a case of unusual anterior course of the vertical segment of the sigmoid sinus which was encountered during an attempted myringoplasty. Anomalies of the jugular bulb in general are also described.
