[Jugular bulb anomaly]

To differentiate and treat correctly the jugular bulb anomalies, as well as to avoid the unnecessarily enlarged operations.

Four cases of jugular bulb anunalies were reported and analysed.

Two of 4 cases were misdiognosed as jugular glomus tumors; One was considered to be jugular bulb anomaly, but was done with an enlarged operation; another one was still accompanied with benign intracranial hypertension syndrome, was inappropriately treated.

The jugular bulb anomaly was often misdiagnosed, therefore the anomaly should be differentiated from the jugular glomus tumor carefully.
