Anomalies of the peritoneum and the colon are quite common. Some of these anomalies can disturb the normal digestive and absorptive functions of the intestine and the others might result in formation of volvulus or impede the blood supply of the intestine. We report a rare, combined variation of peritoneum and ascending colon. In a 70-year-old male cadaver, the greater omentum was very small and extended only for about an inch below the transverse colon. From its lower end, a fibrous band extended to the right wall of the upper part of ascending colon. There was a deep constriction on the right wall of the ascending colon at the site of attachment of the fibrous band. The ascending colon was grossly dilated. Further, the ascending colon was mobile and presented a small ascending mesocolon along its left edge. We discuss the possible embryological basis and clinical and surgical relevance of the case.
