case_images: Abdominal X-ray examination showed a radiopaque object suggestive of a foreign body in the right lower quadrant of the abdomen (Figure 1(a)). Abdominal contrast-enhanced computed tomography (CT) showed that the object had strong artifact with more than 10,000 Hounsfield units, as well as ascites around a thickened terminal ileum (Figures 1(b) and 1(c)).
