BACKGROUND Wandering spleen (WS) is a rare medical condition in which the spleen migrates from its usual position commonly to the pelvis or lower abdomen assuming an ever-wandering state. The incidence of ectopic spleen is 0.2%, with variable clinical manifestations from asymptomatic to abdominal emergency. Symptoms are most attributed to complications related to torsion, so that a nonoperative management of a WS is not advised. According to the literature, 69.5% of patients with WS need splenectomy and 78.6% need laparotomy. CASE REPORT The patient exhibited vague intermittent lower abdominal pain for 6 months due to progressive torsion of the spleen, which resulted in venous congestion. Abdominal investigation revealed a mobile intra-abdominal mass and parenchymatous consistency in the pelvis. Diagnosis by computed tomography outlined abdominal splenomegaly with abnormal position both of pancreas and stomach. Laparoscopy established a giant spleen, with a lengthened pelvic and twisty vascular pedicle. In its ectopic location, the spleen had dragged the pancreas with it, which had taken a vertical position. The classic splenic ligaments were not recognizable. Spleen was removed with median laparotomic incision. Splenectomy was performed to prevent any traumatic fractures of the spleen, a complete twist of the splenic hilum, and the onset of recurrent acute pancreatitis. CONCLUSIONS Wandering spleen is rare in patients presenting with acute abdominal pain. An approach supported by clinical findings and investigation, even considering splenectomy over splenopexy, and laparoscopy over open surgery, may solve and prevent complications and health risks.
