title: Right splenorenal fusion with associated hypersplenism.
abstract: We report the second case of splenorenal fusion and the first occurrence of spleen fusion associated with a right retroperitoneal structure. Hypersplenism was cured by removal of the mass. A concomitant renal cell carcinoma and multiple adenomas within the mass were incidental clinical features. Aside from the rarity of the lesion, its documented occurrence on the right side is significant in that it provides evidence for the possible migration of spleen cells in embryogenesis as an explanation for some other splenic fusion anomalies.
