99(m)Tc-sulphur-colloid and heat-denatured 99(m)Tc-labelled red cell scansdemonstrating a giant intrapelvic spleen in a girl after splenectomy

A 17 x 12 x 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 he at-denatured Tc-99m-labelled red cell scan and Tc-99m-sulphur-colloid scan confirmed the specific red cell sequestration function and reticuloendothel ial activity in the giant intrapelvic spleen. The size and development of t he giant intrapelvic spleen are unusual. The usefulness of functional image s to diagnosis the nature of the intrapelvic mass is well demonstrated.
