A rare case of retroperitoneal mass

Abstract

Accessory spleen or splenunculi is a rare entity and usually near the spleen's hilum and in the tail of the pancreas. The accessory spleen may be formed during embryonic life, and they rise from the left side of the dorsal mesogastrium as a result of the imperfect fusion of separate splenic masses. Here, we are presenting a case of retroperitoneal mass who presented with pain in the upper abdomen, evaluated and worked up and was diagnosed as a large retroperitoneal mass along with two small globular structures likely splenunculi. The patient underwent diagnostic laparoscopy and excision of the retroperitoneal mass. The specimen sent for histopathological examination confirmed the diagnosis as splenunculi.
