title: Aluminum hydroxide gel bezoar--CT diagnosis.
abstract: An obstructing aluminum hydroxide gel bezoar was first recognized on a retrograde gastrografin study through an ileostomy. In retrospect, a computed tomographic (CT) scan had demonstrated the bezoar as a high density intraluminal mass surrounded by somewhat less dense contrast material distending the bowel. A CT image of a phantom made of aluminum hydroxide gel surrounded by gastrografin was remarkably similar.
