title: CT demonstration of a giant colonic diverticulum.
abstract: A case of giant sigmoid colonic diverticulum (GCD) is presented in which plain films showed an unchanging persistent large gas collection that did not opacify on barium enema. The computed tomographic scan revealed the GCD in close apposition to the adjacent sigmoid diverticulosis. Its walls were thin and more irregular than noted on plain films, and there was a suggestion of intraluminal contrast within it.
