Figure 1.

Left upper quadrant longitudinal (A) and transverse (B) abdominal ultrasound scans showing a loop of thickened bowel wall. Presence of intramural air was identified by sub-serosal echogenic foci (arrows), with posterior echogenic shadows (arrowheads); BW: bowel wall; L: lumen (bowel).

Figure 2.

Left upper quadrant ultrasound scan showing loops of thickened bowel with pneumatosis intestinalis (sub-serosal echogenic foci) and color flow Doppler study demonstrating significantly reduced blood flow in the bowel wall. Color flow Doppler artefacts can be observed arising from the intramural air.

Figure 3.

Abdominal X-rays (supine and decubitus) demonstrating mottled shadowing over the left hemi-abdomen which was formally reported to be suggestive of fecal masses.
