Resection of a hormonally active carotid body tumor

Abstract

Treatment of carotid body tumors (CBTs) can be complicated by the presence of hormonal activity. This case describes the treatment of a 65-year-old woman that presented with an abnormally high blood pressure and was found to have a neck mass. Diagnostic imaging along with urine metanephrines revealed this mass to be a hormonally active CBT. Careful resection along with preoperative treatment with an alpha blockade allowed for a successful complete removal of the tumor without any complications. Although CBTs tend to be benign, and hormonally active tumors are rare, one must always maintain a level of suspicion of hormonal activity to prevent catastrophic operative events.
