Cecal bascule herniation into the lesser sac

Figure 1 Computed tomography of abdomen and pelvis showing a loop of distended colon within lesser sac without bowel ischemia or perforation. Radiological features include: (1) the cecum herniated (C) into the lesser sac behind the stomach (S) (A and B); (2) the presence of mesentery (white arrow) between the portal vein and inferior vena cava (A); and (3) the presence of gas or fluid in the lesser sac with its ‘beak’ directed toward the foramen of winslow (B).

Figure 2 Intraoperatively, a cecal bascule was found herniating into lesser sac via foramen of winslow (A). Upon reduction, the cecum appeared viable (B).
