Abstract:
We present a case of an incidentally detected squamous cell carcinoma of the oropharynx on Ga-PSMA-11 PET. A 71-year-old man's condition was diagnosed as prostate carcinoma after a year of rising serum prostate-specific antigen. The staging Ga-PSMA PET/CT demonstrated focal radiotracer uptake in the prostate corresponding to his known primary prostate cancer. However, a PSMA-avid 3.4-cm mass was incidentally found in the right tongue base that was biopsied, confirming squamous cell carcinoma.
