Abstract Objective: To investigate the clinical features and CT signs of ischemic colitis (IC). Methods: Retrospective data analysis of 39 patients’ with IC confirmed by CT and colonoscopy. All patients underwent CT plain scan and dual-phase enhanced scan and some underwent abdominal CTA examination. Results: Of 39 patients, ascending colon was found in 9 cases, transverse colon in 13 cases, splenic flexure of colon in 27 cases, descending colon in 36 cases, sigmoid colon in 11 cases and 1 case of rectum. The colonic wall had a different degree of thickening, with an average thickness of 14.3 mm. The density of all invovling intestinal walls decreased, and the enhancement of the intestinal wall weakened. Intestinal dilatation was observed in 7 cases and 10 cases showed mesenteric edema and exudation. A total of 25 cases of abdominal aortic calcification plaque were detected, 8 cases involved the origin of the superior mesenteric artery and inferior mesenteric artery. Conclusion: The typical CT manifestations of IC included colonic wall thickening and edema, weakened enhancement and surrounding mesenteric edema and exudation. The descending colon and the splenic flexure of colon involvement were the most common. After enhanced scan, the “Reticulated python sign” maybe valuable for the evaluation of intestinal wall ischemia.

Key words： colitis, ischemic tomography, X-ray computed enhanced scan
