CT colonography has become a potential alternative technique to optical colonoscopy for the detection of colorectal polyps and cancer. While considered safer than optical colonoscopy, CT colonography is not without risk. We report a case of colonic perforation during CT colonography using automated CO(2) insufflation and present procedural changes to help minimize the adverse effects of perforation when it occurs.
