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