Abstract :The sigmoid colon is about 40 cm in length and begins below the pelvic inlet and ends at the rectosigmoid junction. It normally lies in the lesser pelvis. Anatomical variations of the sigmoid colon were described by various authors. The length and form of sigmoid colon are the most variable of all colonic segments. In this case, the sigmoid colon was found covering the left half of the transverse colon, hiding the spleen and in contact with the left lobe of the liver. In addition, it had no visible taeniae coli and sacculations. The sigmoid colon was 66 cm in length, 7 cm in lumen width, and in suprapelvic position. Awareness of the possible variation of colon especially of the sigmoid is necessary for adequate clinical, surgical and radiological management.
