Abstract

Chromophobe renal cell carcinoma (RCC) is a rare tumor. We described findings of 18F-FDG PET/CT and 68Ga-FAPI-04 PET/CT of metastatic chromophobe RCC in a 56-year-old woman. 68Ga-FAPI-04 PET/CT demonstrated that the metastatic lesions in the liver, left posterior abdominal wall, and the left waist had intense uptake of 68Ga-FAPI-04, which was higher than that of 18F-FDG on 18F-FDG PET/CT. 68Ga-FAPI-04 PET/CT also delineated the metastatic lesions more clearly than 18F-FDG PET/CT. This case highlights 68Ga-FAPI-04 PET/CT may be promising in restaging of chromophobe RCC.
