Acute Abdominal Pain due to Accessory Splenic Infarction in an Adult: A Case Report

Abstract

Accessory spleens are common congenital anatomic variations that are usually asymptomatic. On the other hand, they can be clinically significant if complicated by hemorrhage, torsion, or infarction. This paper describes a case of an infarcted accessory spleen in a 30-year-old male who presented with abdominal pain. Abdominal CT and MRI revealed an isolated mass, 4.5 cm in size, in the perisplenic area. An infarcted accessory spleen was suspected. The patient underwent laparoscopic accessory splenectomy. Histopathology identified the mass as splenic tissue that had undergone ischemic necrosis. A definitive diagnosis of an infarcted accessory spleen was made, and the patient was discharged on day 5 after surgery symptom-free.
