a–c: Unenhanced (a) and contrast-enhanced CT, transverse plane (b) and sagittal reformation (c). Rounded lesion (white arrow) of the right kidney in a patient after renal allograft transplantation (black arrow). The lesion shows indeterminate enhancement (an increase of 10 HU after contrast injection). The dissected specimen proved to be a papillary renal cell carcinoma. There was no sign of acquired cystic renal disease
