Incidentally Detected High-Grade Follicular Derived Non-Anaplastic Thyroid Carcinoma on Ga-PSMA PET-CT.

Ga--prostate-specific membrane antigen (PSMA)-11 positron emission tomography/computed tomography (PET/CT) is currently routinely used for the evaluation of prostate cancer. However, due to its whole-body imaging capability, it can incidentally identify pathologies beyond prostate cancer. Herein, we describe a case of a 67-year-old man who was recently diagnosed with prostate carcinoma (PCa). The patient had a high PSMA-avid thyroid carcinoma detected incidentally during the initial staging of PCa with Ga-PSMA-11 PET-CT.
