CT showing left renal tumor. Plain CT scan revealed a heterogeneous density in the left renal tumor (A, arrow). The borders between the tumor and abdominal aorta, kidney and renal vein were not clear. Enhanced CT scan suggested a slight enhancement in the arterial phase (B, arrow) and a moderate enhancement in the venous stage (C, arrow).
