Strongylodiasis infestation in a non-endemic area

Strongiloides stercolaris may reside in the intestinal wall asymptomatically for decades and flare up when immunosuppression ensues. We report the case of a patient with hypereosinophilia of unknown origin in whom systemic strongyloidiasis was diagnosed after a course of steroids. The disease presented with recurrent meningitis and duodenal obstruction, and was treated uneventfully with Ivermectine. Probably the parasite was acquired during his stay in Venezuela twenty-seven years before.
