Segmental irregular wall thickening of the sigmoid colon (the segment measure at least 10 cm with a single wall measurement of 10 mm encroaching the lumen however no proximal intestinal obstruction), hairy serosal surface with nodular fat stranding signifying locally advanced disease, few lymph nodes seen in its vicinity with pelvic peritoneal reflection thickening.
