Normal pancreas and splenic variants simulating suprarenal and renal tumors

Two cases of a normal pancreas simulating a renal or suprarenal mass on excretory urography are described. Three cases of unusually shaped spleens and one case of an accessory spleen mimicking renal and suprarenal masses on excretory urography are also presented. The rare entity of splenosis presenting as a renal "mass" on arteriography is also illustrated. The importance of selective arteriography in confirming or establishing the true nature of these pseudotumors which were initially seen on excretory urography is emphasized.
