The spleen is well fixed below the left side of the diaphragm. Wandering spleen is a rare condition of unknown pathogenesis. The wandering spleen is most often localized in the lower abdomen or pelvis. The diagnosis may be difficult if wandering spleen is not suspected. Often a wandering spleen can be palpated in the lower abdomen. In the rare cases of torsion of the splenic vascular pedicle, wandering spleen becomes symptomatic, and splenectomy should be performed. We report a case of a 20-year-old female treated with splenectomy because of torsion of the vascular pedicle.
