A well-defined diverticulum measuring approximately 23 mm is noted arising from the duodenum, without surrounding inflammatory changes. The ascending colon shows long-segment circumferential mural thickening, measuring up to approximately 15 mm, with minimal surrounding pericolic fat stranding. Findings are suggestive of colitis, likely inflammatory/infective in etiology. Less likely neoplastic etiology ( colonoscopy advised ) A well-defined intraluminal/submucosal fat-attenuation lesion is noted within the ascending colon, measuring approximately 2.7 cm, likely representing a submucosal lipoma. Similar small long segment lesion is noted just distal to the above lesion. - Suggested: Clinical correlation / further evaluation if needed
