Overview

Abdominal CT scan is performed in suspected cases of colonic pseudo-obstruction to detect the site of the obstruction. Abdominal CT scan may show the presence of dilation of the large bowel without evidence of mechanical obstruction and the colonic dilation may extend to the rectum.

CT

  • Abdominal CT scan can be performed in suspected cases of acute colonic pseduo-obstruction in order to detect the site of the obstruction. The CT scan also can detect the underlying cause or risk factor that lead to the colonic obstruction.[1]
  • CT scan in cases of acute colonic pseudo-obstruction may show the following:
    • The presence of dilation of the large bowel without evidence of an abrupt transition point or mechanically obstructing lesion
    • The colonic dilation may extend to the rectum
