Thickened segment of sigmoid colon with diverticulae. Pericolonic fat stranding which extends superiorly around the descending colon with associated prominent lymph nodes. Colon is dilated measuring up to 7 cm (transverse colon) and 10.5cm (caecum) up until the thickened sigmoid segment. Gas and faeces are present in the rectum. Small bowel is collapsed but appears unremarkable. No free gas or free fluid. Prominent mesenteric and para-aortic lymph nodes without lymphadenopathy by size criteria.
Conclusion: Thick walled segment of proximal sigmoid colon causing incomplete bowel obstruction. Associated with diverticulae regional fat stranding likely reflects coexistent diverticulitis. Malignancy cannot be excluded on this study. There are thick bands of soft tissue tethered to adjacent ileum and bladder dome, both of which are distorted.
