Acute abdomen due to torsion of wandering spleen: CT diagnosis.

Two adults and a child with acute abdomen and surgically confirmed torsion of wandering spleen are presented. Computed tomography provided a spectrum of findings including an ovoid or comma-shaped abdominal mass, hypertrophy of the liver's left lobe, a whirled appearance of hyperdense, nonenhancing splenic vessels, and an enlarged spleen, exhibiting minimal or no enhancement. Computed tomography also indicated the point of torsion and the viability of splenic parenchyma.
