We report a case of colonic perforation in CT colonography, which was observed in a sigmoid colon segment contained within an inguinal hernia. At surgery, apart from the perforation, a normal large-bowel wall was found. Although rare, perforation may occur in patients with normal bowel wall, possibly resulting from a mechanical strain caused by gaseous overdistention. Radiologists performing the procedure must be aware of this possibility.
我们报告一例在CT结肠成像中发现的结肠穿孔病例，该穿孔发生在腹股沟疝内的一段乙状结肠。手术中，除穿孔外，发现大肠壁正常。尽管罕见，但肠壁正常的患者也可能发生穿孔，这可能是由气体过度扩张引起的机械性张力所致。进行该检查的放射科医生必须意识到这种可能性。
