^{99 m}Tc-sulphur-colloid and heat-denatured ^{99 m}Tc-labelled red cell scans demonstrating a giant intrapelvic spleen in a girl after splenectomy

Abstract

A 17 × 12 × 5-cm giant intrapelvic mass in a 14-year-old girl is reported. This mass developed 6 years after a splenectomy for splenic torsion. The heat-denatured ^{99 m}Tc-labelled red cell scan and ^{99 m}Tc- sulphur-colloid scan confirmed the specific red cell sequestration function and reticuloendothelial activity in the giant intrapelvic spleen. The size and development of the giant intrapelvic spleen are unusual. The usefulness of functional images to diagnosis the nature of the intrapelvic mass is well demonstrated.
