Abstract:
:We present a case of a 55-year-old man with a history of poorly differentiated metastatic thyroid cancer, which is rare and shows aggressive behavior. The patient had radioactive iodine-negative multiple metastasis on F-FDGPET/CT, therefore Ga-DOTATATE and Ga-PSMA PET/CT were performed whether an opportunity exist for DOTATATE or PSMA-directed radionuclide therapy. Different patterns of tumoral uptakes were detected on F-FDG, Ga-DOTATATE, and Ga-PSMA PET/CT, as a demonstration of tumor heterogeneity.
