Torsion of a huge accessory spleen in a 20-year-old patient()

INTRODUCTION: Accessory spleen is a rare condition. Torsion of accessory spleen can lead to acute abdomen. PRESENTATION OF CASE: We describe a young woman with an acute abdomen caused by torsion of accessory spleen. Abdominal computed tomography angiography (CTA) demonstrated an ischemic giant accessory spleen with a twisted vascular pedicle. An emergency laparotomy was performed with resection of the infarcted accessory spleen. DISCUSSION: Accessory spleen is a rare and asymptomatic condition. Torsion of accessory spleen is also uncommon. Abdominal pain is the main symptom. CTA is effective in reaching a diagnosis. Definitive treatment of an acute abdomen due to accessory splenic torsion is emergency accessory splenectomy. CONCLUSION: Elective accessory splenectomy should be recommended for known giant accessory spleen to prevent complications in future.
