X rays can be useful in the diagnosis of strongyloidiasis. Radiographic findings are variable, depending upon the stage and extent of infection which includes pulmonary infiltrates, when present, may be alveolar or interstitial, diffuse or focal, uni- or bilateral. Lung consolidation, occasional cavitation, and even abscess formation can also be found. Plain abdominal radiographs and contrast studies can reveal worm masses in bowel loops. Chest radiographs are explained by pulmonary migration of the parasites and by different types of bacterial super-infection, particularly gram-negative bacilli.

A chest X-ray can reveal varying sizes of oval or round infiltrates (Löffler’s syndrome). These infiltrates usually resolve spontaneously. Other findings include:

• Segmental or lobar opacities
• Pleural effusion
• Cavitations and abscesses

Plain abdominal radiographs and contrast studies can usually reveal worm masses in bowel loops.

Other findings include:

• Ulcerations
• Strictures
• Intestinal narrowing due to strictures and fibrosis
