Patient Data

Gender: Male

A 35 mm well defined cystic solid mass is seen in the upper pole of the right kidney. The neoplasm has a mildly lower density to normal renal parenchyma on non-enhanced CT scan. Post-contrast nephrographic-phase CT scan shows that the mass enhances less than normal renal parenchyma. No local invasion to adjacent structures is noted. The renal vein is intact. 
A few simple cortical cysts less than 15 mm in diameter also are seen at both kidneys.
The prostate gland is mildly enlarged.
Degenerative changes as osteophytes are seen at the lumbar spine.
