[Radiological aspects of the duodenum and small intestine in severe strongyloidiasis. Apropos of 4 cases].

Four cases of severe strongyloidiasis in Martinique patients are reported. Clinical features were typical of the affection, and the outcome was fatal in two cases. Fibroscopy findings were negative but larvae were demonstrated in biopsy specimens in 3 out of the 4 cases. A barium meal follow-through examination showed the different radiological images of the infestation: non-specific parasitic duodenitis and pseudo-stenosis of D3 with duodenal dilatation, barium reflux into the main bile duct, and absence of jejunal folds, these images being very suggestive of strongyloidiasis.
