On further examination, an inflammatory process was identified in the pelvis involving an omental inflammatory adhesion to the region of the distal sigmoid colon (Fig. 1a). The inflamed omentum was gently dissected off an adhered sigmoid appendix epiploica, which appeared secondarily inflamed (Fig. 1c). Once mobilized, the omentum demonstrated a thin projection that had torted and had subsequently become necrotic (Fig. 1b).
