Wandering spleen is a rare condition presenting as the spleen being found somewhere different from its usual location due to thelooseness of the peritoneal ligaments of the spleen. Its occurrence rate among the major splenectomy series in medical literatureis less than 0.5%. It usually presents itself between the ages of 20 and 40 and the majority of the patients are women. A 20-yearold female patient with recurrent abdominal pain was admitted to our emergency clinic with abdominal pain going on for 3 days,nausea, vomiting and loss of appetite. Computerised Tomography (CT) indicated a pelvis localised spleen and an infarctus dueto a non-homogenous parenchyma area. The patient was operated on with a provisional diagnosis of wandering spleen. Duringexploration a relatively large, congested and mobile spleen was found in the pelvis and a splenectomy was performed. The wanderingspleen presents itself on a spectrum ranging from asymptomatic to acute abdomen. Symptoms usually arise from complicationsrelated to torsion. The surgical methods performed on wandering spleen are splenorraphy and splenectomy. The deciding factorfor determining the treatment method is the existence of infarction in spleen. Wandering spleen is very rare and a cause for acuteabdominal pain, we think it is important to consider it for differential diagnosis in cases with acuteabdominal pain, especially thecases with intra-abdominal mass findings, for an accurate diagnosis and treatment plan.
