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.
