We report the case of a 49-year-old white man with a chromophobe renal cell carcinoma associated with sarcomatoid differentiation, an uncommon yet an aggressive form of dedifferentiated renal cell carcinoma. In opposite to the conventional renal cell carcinoma, which may not always demonstrate avid FDG activity, the sarcomatoid differentiated chromophobe renal cell carcinoma shows intense FDG uptake on PET. This case highlights the role of FDG PET/CT in staging and restaging this type of rare renal cell carcinoma.
