ABSTRACT

Splenosis is a condition in which ectopic spleen tissue may be found in the peritoneal cavity or in other unusual locations due to heterotopic auto-transplantation and implantation of splenic tissue after splenic trauma or splenectomy. It is a benign condition that is often misdiagnosed as a tumor; therefore, knowledge of this condition is important when evaluating patients with a history of splenic trauma or splenectomy and newly appearing peritoneal lesions. Herein, we describe computed tomography and magnetic resonance imaging findings of two cases of subdiaphragmatic intraperitoneal splenosis located along the hepatic surface, mimicking neoplastic lesions.
