Torsion of a visceroptosed spleen.

Torsion of the pedicle of a visceroptosed spleen, a rare condition, was diagnosed preoperatively in a 4-year-old girl, with the aid of history, physical examination, blood smear findings, splenic scans with technetium Tc 99m sulfur colloid, and selective angiography. A splenectomy was performed, and the child made an uneventful recovery. This case report illustrates some of the diagnostic and therapeutic considerations pertaining to torsion of the spleen.
