Torsion of an Accessory Spleen: A Rare Case and Review of the Literature

Koichi Kato, Shohei Honda,

Abstract

Torsion of an accessory spleen is a very rare entity that causes an acute abdomen in children, and it is difficult to accurately diagnose preoperatively. We herein report a case of acute abdominal pain in a 5-year-old boy caused by torsion of an accessory spleen. In this case, abdominal US detected the whorl of the twisted pedicle, which may be a hallmark to diagnose torsion of an accessory spleen. We must consider torsion of an accessory spleen as a differential diagnosis when encountering acute abdomen in children with a palpable mass.
