Mass at the splenic hilum: a clue to torsion of a wandering spleen located in a normal left upper quadrant position.
Wandering spleen is an extremely rare condition in which the spleen is lacking its normal ligamentous attachments and therefore can move to an ectopic position in the abdomen or pelvis. Wandering spleen predisposes the patient to life-threatening complications due to torsion of the spleen's vascular pedicle, with resulting splenic infarction, portal hypertension, and bleeding. Because of the nonspecific symptoms, imaging plays an important role. To our knowledge, only a few case reports describing wandering spleen in the pediatric population have been published, including 2 cases in infancy. We report a case of splenic torsion in an infant with a preoperative diagnosis made on the basis of color and power Doppler sonography. The diagnosis was confirmed by contrast-enhanced helical computed tomography (CT) and proved at surgery. On sonography, a diffusely hypoechoic spleen and a mass at the splenic hilum representing the torsed splenic pedicle were shown. The splenic hilar mass correlates with the CT "whirl" sign indicative of torsion.
