Presentation
Swelling on right side of neck for 1 year. Systemically stable. He was initially evaluated with ultrasound which demonstrated a hypervascular mass situated at the right common carotid artery bifurcation, spraying the bifurcation.
Patient Data
The study demonstrated a T2 hyperintense mass with prominent flow voids, giving the "salt and pepper" sign typical of a paraganglioma (glomus tumor). In this case, the position of the tumor is classic of the carotid body tumor. It was difficult to identify the main feeder but likely branches of the external carotid artery.
Case Discussion
This case demonstrated very well the "salt and pepper" sign seen in paraganglioma. This patient is yet to undergo surgery and such histology is not available to confirm the diagnosis.
