title: Perirenal lipoma versus renal cell carcinoma.
abstract: Pure renal and perirenal lipomas are rare. They arise from renal cortex, capsule, or perirenal tissue, and may be difficult to distinguish from renal adenocarcinomas. We report on a patient who presented with a renal mass that had the radiologic findings suggestive of a renal cell carcinoma, but proved to be a simple lipoma.
