Masses in carotid space can be of varied etiology. These usually displace the parapharyngeal space anteriorly. They can arise from various structures and may be cystic or solid. Carotid body tumors are neural crest in origin and usually cause splaying of carotid vessels resulting is “Lyre sign”. Presented in this case report is a hypermetabolic mass resulting from mycotic aneurysm mimicking carotid body tumor.
