Overview

Radiographs can be useful investigations in the diagnosis of ascariasis.

Xray

Chest X-ray

A chest x-ray can reveal varying sizes of oval or round infiltrates (löffler's syndrome). These infiltrates usually resolve spontaneously.

Abdominal X-ray

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

Intestinal ascariasis on fluoroscopy- The worm appears as parallel bands (arrow) if its alimentary tract is distended. On transverse sections, the worm appears as a target sign (arrowhead) with body wall and a central dot representing its gut.
