Abstract:
Metastatic medullary thyroid carcinoma (MTC) can exhibit variable progression, with liver metastases occurring in up to 62% of cases. We report an unusual case of 50-year-old man with progressive MTC and atypical hypodense metastasis in the left lobe of liver that showed no tracer avidity on conventional 18 F-FDG and 68 Ga-DOTATATE PET/CT but was intensely avid on 68 Ga-DOTA-FAPI-04 PET/CT, implying a possible role of FAPI PET/CT imaging in diagnosing unusual metastatic lesions that may be missed on conventional PET imaging and also its theranostic potential for future management.
