Bilateral carotid body tumours: a case report from surgeon's perspective.

Carotid body tumour (CBT) is the most common paraganglioma of the head and neck and may compromise neurovascular structures such as carotid vessels, and cranial nerves. Intracranial extension from the mass is possible if left untreated. The main treatment for CBT is surgical resection albeit extremely challenging due to tumour hypervascularity and its relationship to the carotid artery. A bilateral CBT, however, is a rare occurrence. Herein, we present a case of a man who presented to us with bilateral painless and palpable neck mass. He underwent staged bilateral CBT excision and it was complicated with left hypoglossal nerve palsy, which recovered over time.
