Overview
The CT scan is very sensitive (98%) in diagnosing diverticulitis. It may also identify patients with more complicated diverticulitis, such as those with an associated abscess. CT also allows for radiologically guided drainage of associated abscesses, possibly sparing a patient from immediate surgical intervention.
Computed Tomography
- Colonic and paracolic inflammation in the presence of underlying diverticula (diverticula are identified on CT scans as outpouchings of the colonic wall).
- Symmetric thickening of the colonic of approximately 4-5 mm is common.
- Enhancement of the colonic wall is commonly noted. This usually has inner and outer high-attenuation layers, with a thick middle layer of low attenuation.
- Free diverticular perforation results in the extravasation of air and fluid into the pelvis and peritoneal cavity.
- Air in the bladder in the presence of a nearby segment of diverticulitis is suggestive of a colovesical fistula.
