Overview
A barium enema is the mainstay of diagnosis of Hirschsprung’s disease. Barium enema findings suggestive of Hirschsprung's disease include a transition zone between the narrow and dilated portions of the colon in the shape of an inverted cone is the most characteristic radiologic finding.
Other Imaging Findings
Barium Enema
Barium enema findings suggestive of Hirschsprung's disease include:
- Barium enema studies demonstrate patency of the colon, which is short but usually normal in caliber.
- A transition zone between the narrow and dilated portions of the colon in the shape of an inverted cone is the most characteristic radiologic finding.
- When this transition zone is observed, the examination should be discontinued because filling of the more proximal dilated bowel beyond the transition zone may lead to impaction.
- The radiologic diagnosis of total colonic aganglionosis is difficult. Findings at barium enema examination may be normal or may include a short colon of normal caliber, microcolon, or a transition zone in the ileum.
