Ninety-eight children with recent blunt abdominal trauma which initially evoked clinical suspicion of splenic injury were examined with colloid scintigraphy of the spleen and the liver using multiple imaging views and with abdominal survey. Nineteen children were, in addition, examined with tomographic scintigraphy. The clinical findings and the course of the disorder were reanalyzed. Scintigraphy indicated splenic injury in 56 children and hepatic injury in another 5 children. The left lateral and the left oblique were the optimum imaging views for detecting splenic ruptures. Tomographic scintigraphy did not improve the diagnostic yield. Abdominal survey failed to indicate almost every second case of splenic rupture and provided no additional information of significance. The clinical review agreed with the scintigraphic diagnosis of splenic lesions but, in addition, it suggested possible splenic lesions in another 10 children with normal scintigraphy. This discrepancy cannot be explained as surgery was not employed; the occurrence of splenic lesions too small to become detectable at scintigraphy or to provoke clinically evident symptoms may be supposed.
