Splenosis presenting as a left renal mass: a report of two cases.

The development of splenosis is a recognized consequence of splenic trauma. We present 2 cases of splenosis that were initially diagnosed as left renal cell carcinomas. The diagnosis of splenosis was made by technetium sulfur colloid scans. The clinical presentation and diagnosis of these 2 cases of splenosis masquerading as renal cell carcinoma are reviewed.
