Accessory Wandering Spleen: Report of a Case of Laparoscopic Approach in an Asymptomatic Patient

Introduction: Accessory wandering spleen is a rare but dangerous condition. Abnormalities of the ligamentous apparatus of an accessory spleen may evolve into torsion of its vascular axis, which can lead to a splenic infarct making surgery necessary. Patients are often asymptomatic and the diagnosis can be accidental. An early diagnosis and a correct treatment are fundamental.

Presentation Of Case: In this case report a young woman underwent laparoscopic surgery after an incidental finding at a Pelvic Ultrasound of an accessory wandering spleen.

Discussion: In literature are reported cases of asymptomatic patients with an accessory wandering spleen treated with a conservative approach. However, a torsion or infarct of the accessory wandering spleen leads to emergency surgery. The presence of an independent vascular axis of the accessory spleen reduces the risk of postoperative complications (e.g. thrombocytosis) and the administration of low molecular weight heparin should prevent the risk of portal thrombosis.

Conclusion: We suggest performing surgery with a laparoscopic approach in patients with accessory wandering spleen, though asymptomatic, because of the risk of serious complications in case of accessory spleen torsion.
