Abstract

Right sided sigmoid colon, rare anomaly was observed in a male cadaver of 45 year during routine dissection classes for first year medical students. The descending colon passed down to the left iliac crest and then crossed the middle line in front of the 3rd lumbar vertebra. It then passed to the right iliac fossa behind the free end of the caecum. The sigmoid colon beginning on the fossa passed down into the pelvic cavity, crossing the right brim of the pelvis and reached the left side of the sacrum to end in the rectum. The meso-sigmoid was attached to the right side from the ilio-caecal junction to the middle of the sacrum. The blood supply was derived from inferior mesenteric artery. The embryological reason and clinical importance of the condition is discussed.
