  1. MRI: Ulcerative Colitis

    show more
    Description: Main Feature: Large bowel wall thickening. Description: There is diffuse circumferential wall thickening, hyperintense T2 signal, and avid mucosal enhancement throughout the entire colon and rectum. Increased mesenteric fat stranding surrounding the bowel with prominence of the mesenteric vessels. The terminal ileum is grossly unremarkable. These findings are suggestive of ulcerative colitis. Series 30, image 5096-axial/t1, precontrast. This picture is to be used together with the series 39, image 5096. The point of focus here is the descending colon located at the 1-2 o’clock position. Notice that the bowel wall is circumferentially thickened on both the pre and post contrast image. On series 39, you see that same portion of the colon wall diffusely enhance. Also, in series 39 note the engorged vessels that feed the colon. Series 39, image 5096-axial/t1, postcontrast. Series 24, image 29- t2 axial. At the level of the sigmoid colon. The purpose of this image is to show diffuse circumferential wall thickening in one continuous segment, hyperintense t2 signal, and mucosal enhancement.

  9. Rectum, sessile polyp

    show more
    Description: Rectum - sessile polyp Polyp is any growth or mass protruding from a mucous membrane. Polyps may be attached to a membrane by a thin stalk (pedunculated polyps), or they may have a broad base (sessile polyps). They are usually an overgrowth of normal tissue, but sometimes they are true tumors (masses of new tissue separate from the supporting membrane). Usually benign, they may lead to complications or eventually become malignant. They can occur wherever there is mucous membrane: in the nose, ears, mouth, lungs, heart, stomach, intestines, urinary bladder, uterus, and cervix. Sessile polyp is any form of polyp that has a relatively broad base.

    show more
    Description: Colon - small colonic polyp (juvenile retention) A hereditary or acquired pedunculated neoplasm arising from the colonic mucosa; small CPs are usually benign, but may become malignant; like colorectal CA, CPs may present with occult bleeding.
