Tuboovarian abscess simulating giant colonic diverticulum

Emphysematous cystitis after orchiectomy

A 59-year-old man developed emphysematous cystitis 3 weeks after undergoing left orchiectomy because of suppurative epididymitis. The case is presented because of its unusual cause and to emphasize the high degree of suspicion required for the diagnosis.

Giant diverticulum of the sigmoid colon

While diverticulosis of the colon is a relatively common disease, a solitary giant diverticulum (GD) of the sigmoid is rare. Although there exist some theories about the formation of a GD, none is really conclusive. Symptoms are similar to diverticular disease, and diagnosis is easy with the aid of radiology. Early surgical treatment is necessary since the complication rate is high (19%).

CT demonstration of a giant colonic diverticulum

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.
