Wandering spleen, or hypermobile spleen, arises from the elongation or maldevelopment of the spleen's suspensory ligaments. This condition is a rare clinical entity, primarily affecting children, with a higher prevalence among adult females in the active reproductive age group. Manifestations may include an asymptomatic abdominal mass or intermittent abdominal discomfort due to the torsion and subsequent spontaneous detorsion of the spleen. This case report details the presentation of a 14-year-old female initially misdiagnosed as having gastroenteritis who later experienced acute abdomen. Subsequent ultrasonography and computed tomography scan revealed splenic torsion, confirmed during exploratory laparotomy, which demonstrated an infarcted spleen. The definitive therapeutic intervention was a total splenectomy. This clinical entity should be taken into account in the differential diagnosis of acute abdominal pain in order to aid in early diagnosis and management. This could allow us to avoid splenectomy whenever possible and instead do splenopexy, especially in pediatric cases, as the spleen plays a crucial role in the reticuloendothelial system.
