A 100×68×70 mm mass is seen in the lower pole of the right kidney. The neoplasm has a similar density to normal renal parenchyma on a nonenhanced CT scan. After IV contrast media injection, the attenuation value increased from 35 to 67 HU. A nephrographic phase CT scan shows that the mass enhances less than normal renal parenchyma.
An enlarged lymph node with SAD of 9 mm is present in the paracaval region adjacent to the renal hilum. There are no sign of local invasion to the adjacent structures and no vascular extension.
A 12 mm stone is noted at the upper calyx of the right kidney.
The prominent median umbilical ligament is seen.
