Carotid body tumors are rare neoplasms arising from chromaffin cells located at the carotid bodies. They present clinically as a painless slow-growing mass in the neck, usually anterior to the sternocleidomastoid muscle. They can be asymptomatic or cause local compressive symptoms such as dysphagia, odynophagia, or, more rarely, symptoms associated with catecholamine secretion. Diagnosis is based on the clinical characteristics and imaging findings on ultrasound, computed tomography and magnetic resonance. Angiography has a limited diagnostic role, but it is currently used for the embolization of these tumors before surgery. Here we present our recent experience with two patients with carotid body tumors who underwent the preoperative embolization procedure.
