Obtain a chest radiograph to reveal possible patchy alveolar infiltrates in acute strongyloidiasis. In severe strongyloidiasis, findings are diverse; the chest radiograph may depict diffuse interstitial infiltrates, segmental or diffuse alveolar infiltrates, or pleural effusions. In severe cases, bronchopneumonia (either segmental or lobar opacities) may be seen. In these patients, clinical progression to acute respiratory distress syndrome may occur. Occasionally, pulmonary effusions may occur. Lung cavitation and abscesses have been described in association with secondary bacterial infection.

A plain abdominal radiograph may reveal loops of a dilated small bowel, or ileus, in severe strongyloidiasis; other findings may include duodenal edema, with loss of the mucosal pattern; ulcerations; strictures; rigidity, and tubular narrowing. The strictures and ulcerations may mimic inflammatory bowel disease.

Barium swallow and barium enema findings may be normal, may exhibit bowel dilatation, or may indicate stenosis with ulceration.
