Although PSMA-targeted PET imaging is predominantly used for prostate carcinoma (PC), it has also been reported for thyroid carcinoma (TC). A 77-year-old man had a liver metastasectomy for poorly differentiated TC, which had elevated F-18-FDG uptake. Two years later, he was diagnosed with acinar-type modified Gleason score of 7 (3 + 4) PC. Four years later, he had metastatic liver lesions that had no radioactive iodine and F-18-FDG avidity. These lesions were Ga-68-PSMA avid, and the biopsy confirmed TC metastasis. This case emphasizes the importance of Ga-68-PSMA-based imaging in poorly differentiated TC and pathological confirmation for lesions that were Ga-68-PSMA-positive.
