The aberrant jugular bulb.

The aberrant jugular bulb has been found in 0.5-7.0% of autopsy cases. Its primary interest lies in the appreciation of its benignancy, its occasional symptomatic behavior and of the consequences of failing to glean its true nature of surgery. Therefore, the importance of proper preoperative diagnostic evaluation must be stressed so that operative interference with an anomalous but otherwise normal structure can be avoided.
