Transplantation of splenic tissue is a rare condition that usually occurs after splenic trauma and splenectomy. It usually requires surgery for diagnosis and treatment. A 38‑year‑old Asian male with familial hemolytic disease underwent laparoscopic splenectomy for a traumatic rupture of the spleen one year prior. The patient developed middle‑upper abdominal pain without any obvious cause, radiating to the back and chest seven months prior to presentation. The condition improved with conservative treatment but the patient experienced recurrent episodes. Abdominal CT suggested multiple gallstones in the gallbladder that changed after splenectomy and multiple nodules in the original splenic area; thus, transplantation of splenic tissue was considered. MRI suggested thick gall bladder bile, multiple stones and cholecystitis, and the spleen was not observed (the patient underwent laparoscopic splenectomy at our hospital one year previously due to traumatic splenic rupture); furthermore, there were multiple abnormal signal foci in the splenic area, so the possibility of spleen implantation was considered. Considering the patient's family history of a hereditary hemolytic disease, laparoscopic cholecystectomy was performed simultaneously with laparoscopic accessory splenectomy. The final pathological report revealed chronic cholecystitis, mixed calculi, red pulp dilation, hyperemia and bleeding in round tissue with blood clot formation and acute and chronic inflammatory cell infiltration. Clinicians must bear in mind the possibility of splenosis after splenic trauma and its image variations.
