Omental torsion diagnosed by abdominal contrast-enhanced computed tomography: A case report

Figure 1 Contrast-enhanced computed tomography. A-D: Contrast-enhanced computed tomography revealed thickening of the omentum in the right abdomen, with the omentum twisting spirally along its axis and having blurred edges.

Figure 2 Laparoscopic surgery view. A and B: Laparoscopy revealed 50 mL of dark-red bloody ascites in the pelvis and twisting of the right omentum along its longitudinal axis, with a 10 cm × 8 cm purple-black necrosis at the distal end.

Figure 3 Open surgical view. The right-sided omentum was found to be twisted clockwise by 1980 degrees.

Figure 4 Postoperative pathology. Histopathological examination revealed omental hemorrhage, degeneration, and necrosis (hematoxylin and eosin, × 50).
