Right lateral neck painless swelling prompted for medical imaging.
Patient Data
Rather well defined avidly enhancing soft tissue mass in the anterior triangle of the right neck at the carotid bifurcation with characteristic splaying of the internal carotid artery and external carotid artery. The lesion is measuring approximately 2.4 x 2 x 3.8 cm at maximum AP, TV, and CC dimensions respectively.
No evidence of adjacent infiltrative or inflammatory changes.
Cervical spondylotic changes with narrowed C6/7 disc space are incidentally seen.
Case Discussion
A carotid body tumor (also called chemodectoma or carotid body paraganglioma) is a vascular paraganglioma located at the carotid bifurcation. It causes splaying of the internal and external carotid arteries.
