Ectopic spleen is a rare splenic malformation. Apart from torsion of the vascular pedicle, a common complication, an ectopic spleen could be responsible of an acute intestinal obstruction. We report a case of an 8-year-old girl who presented an acute abdomen, following of the transverse colon strangulation by the torsion of the vascular pedicle of a wandering spleen. The patients benefited a surgical opening into the abdomen who has been confirmed the diagnosis and made a detorsion of the vascular pedicle of spleen with splenopexy.The interest of this case report lies on the rarity of a wandering spleen and on the unusual situation of transverse colon strangulation by the vascular pedicle of spleen.
