A 42-year-old male with a pathologically proven papillary renal cell carcinoma in the right kidney. A: On an axial T2-weighted magnetic resonance image. The well-circumscribed exophytic solid tumor (arrow) shows relatively homogeneous low T2 signal intensity; B: On an axial contrast-enhanced T1-weighted magnetic resonance image during the corticomedullary phase. The tumor (arrow) is homogeneously hypovascular compared to the adjacent renal cortex, except for mild enhancement of the renal capsule.
