Large Cavernous Hemangioma of the Kidney Mimicking a Renal Cancer: A Diagnostic Challenge

Hemangioma
A 69-year-old man presented with a 9-months intermittent macroscopic painless hematuria. He had a previous left kidney surgery for renal lithiasis 24 years ago. There were no particular physical findings, such as flank pain.

Routine laboratory tests including hematology, biochemistry, urine analysis and coagulation tests showed no abnormalities. Urine cytology studies and cultures were negative.

Renal ultrasound depicted an enlarged left kidney with heterogeneous solid mass. An enhanced computed tomography (CT) revealed a 10 × 9 × 8, 5 cm, low-density, large heterogeneous renal mass.
