Congenital spleen thinning mimicking a space-occupying lesion.

By splenic imaging, a large focal defect was demonstrated in a symptomatic South American immigrant with simultaneous parasitic infestation of strongyloidiasis and entamebiasis. The CT scan also was thought to be abnormal. Pathologic findings reported a variation in splenic configuration. Unusual splenic configuration should be considered in the differential diagnosis of abnormal scans.
