7cm mass with central necrosis in the mid and lower pole of the left kidney.  The mass extends into the lower pole branch of the left renal vein and extends beyond the capsule to abut Gerota's fascia.

Simple cysts in both kidneys.

No solid organ, adrenal or peritoneal metastases.

No infradiaphragmatic lymphadenopathy.  No bone lesion.

Case Discussion

Renal cell carcinoma metastases as in this case are typically hypervascular as with the primary tumor.

The radiological stage for this case T3a,N0,M1 (brain).

The T3a stage relates to both its extension into segmental veins and the perirenal tissues.
