Abstract
A 14-year-old boy had a past medical history of splenectomy for trauma at 2 years old. Because of intermittent abdominal pain and vomiting, he was taken to the emergency room. Contrast-enhanced CT showed beak sign as a sign of small bowel obstruction, and laparotomy was therefore performed. A small mass was incarcerated within a loop consisting of an adherent band. The band and mass were excised. Histopathological examination showed splenic tissue. Small bowel obstruction was triggered by splenosis. If a patient with a history of splenic injury or splenectomy complains of abdominal symptoms, splenosis must always be considered as a differential diagnosis.
