“…The carotid body is the largest collection of paraganglia in the head and neck and can be the site for carotid body tumors (CBTs). CBTs, also known as chemodectomas, are typically slow-growing, extra-adrenal tumors of neuroendocrine origin which arise from either sympathetic or parasympathetic paraganglia throughout the body [ 2 , 3 ]. CBTs are rare, highly vascular tumors that comprise only 0.3% of all paragangliomas but 60% of head and neck paragangliomas.…”

Carotid body tumors (CBTs) are a rare form of paragangliomas that often arise near the carotid bifurcation. They are typically slow growing and often asymptomatic. We report a case of a CBT in a 70-year-old man, who presented with a firm, painless, pulsatile neck mass that rapidly increased in size over the course of two months. The diagnosis was suspected based on the patient’s clinical history and physical examination. The diagnosis was confirmed with CT angiography (CTA). The tumor was nonfunctioning based on normal urinary-free catecholamines, vanillylmandelic acid (VMA), and metanephrines levels. The patient then underwent a CT scan of his thorax, abdomen, and pelvis which did not detect any metastatic spread. The patient was referred to a tertiary vascular surgery center for definitive treatment. Our aim in presenting this case is to increase awareness of this rare type of paraganglioma with the hope of increasing early intervention and improving outcomes.
