Figure 1

Supine abdominal radiograph. There is minimal visible bowel gas. Several loops of the small bowel are visible due to the presence of residual barium from a swallow study three days before. Segments in the right lower quadrant are particularly abnormal with the barium forming a dense cast-like appearance (arrows).
