Overview
Meckel's diverticulum appears as a tubular, round, blind-ended and inflamed structure in the right lower quadrant or periumbilical region. Mural thickening and contrast material enhancement may be seen in the wall of the diverticulum. It also helps rule out appendicitis in patients, which has a similar presentation.
CT
Features of CT in patients with Meckel's diverticulum are as follows:[1][2][3][4][5][6]
- Standard CT may not routinely show a bleeding diverticulum.
- CT scan demonstrates Meckel's diverticulum as a blind-ended, tubular, round or oval structure structure in the right lower quadrant or periumbilical region with surrounding inflammation.
- The wall of the diverticulum may show inflammatory changes such as mural thickening and contrast material enhancement.
- Soft-tissue stranding and adjacent fluid collections are also helpful features for the diagnosis of diverticulitis.
- Occasionally enteroliths may be present within the inflamed diverticulum.
- CT scan also helps rule out appendicitis in patients with similar symptoms.[7]
- Ct scan may show features of intestinal obstruction as a complication of Meckel's Diverticulum.[8]
