Carotid body tumors, although representing about 65% of head and neck paragangliomas, are rare neoplasms. Doppler ultrasonography, contrast-enhanced computed tomography (CECT), and MRI have been routinely used in the diagnosis of carotid body tumor. We hereby represent a case of 56-year-old male suspected to have lymph node metastasis from carcinoma pyriform sinus detected as carotid body tumor in fluorodeoxyglucose positron-emission tomography-CECT imaging and subsequently confirmed by histopathology.
