Elevated 68 Ga-FAPI Activity in Benign Carotid Body Tumors.

We present 68 Ga-FAPI PET/CT findings of benign carotid body tumor in a 33-year-old woman. Benign carotid body tumor demonstrated intense tracer uptakes on 68 Ga-FAPI PET/CT. Our case suggests that benign carotid body tumors should be considered in the differential diagnosis of neck mass with elevated 68 Ga-FAPI activity.
