Renal Cell Carcinoma

History: 50 year old male with new onset left flank pain and hematuria. No prior past medical history. 

Single axial CT scan with IV contrast through the abdomen in arterial phase at the level of the pancreas reveals a large enhancing left kidney mass with areas of central necrosis.

This patient went on to have a radical left nephrectomy and the tumor pathology was clear cell renal cell carcinoma (RCC), the most common type of RCC.
