CT abdomen general
The general principles of the CT abdomen examination.
Pathology - Intestines
Diverticulitis
Colonic diverticula originate primarily in the sigmoid and descending colon. Right-sided diverticula do occur, but much less frequently. One of the diverticula may become infected. As a result, the mesocolon surrounding the diverticulum will have an increased density (fig. 32). There will also be segmental diffuse wall thickening of the affected part of the colon. Diverticulitis usually responds to conservative treatment with dietary modifications. However, diverticulitis may be complicated by perforation and/or the formation of abscesses. When the intestine is perforated, air in the intestine moves through the wall defect into the abdominal cavity. An abscess is an encapsulated collection of fluid (pus) with enhancement of the wall.
