The computed tomographic (CT) appearance of two cases of sigmoid colon volvulus is described. Both underwent plain abdominal radiographs, contrast enema, and CT. The findings of sigmoid volvulus at CT were characteristic, having a whirl pattern of the dilated sigmoid loop around mesocolon and vessels and a bird-beak aspect of the afferent and efferent segments. CT may be valuable in a case of unusual clinical or plain film presentation as an alternative to contrast enema.
描述了两例乙状结肠扭转的计算机断层扫描（CT）表现。两例患者均接受了腹部平片、钡剂灌肠和CT检查。CT上乙状结肠扭转的表现具有特征性，扩张的乙状结肠袢围绕结肠系膜和血管呈漩涡状，输入段和输出段呈鸟嘴样。对于临床或平片表现不典型的病例，CT作为钡剂灌肠的替代检查可能很有价值。
