摘　　要：目的:对5例肠旋转不良伴中肠扭转的影像表现进行回顾性分析,总结经验教训,提高对本病的CT影像认识。方法:本组5例,男4例,女1例,均做CT检查,将影像表现与手术结果相对照,CT检查采用Philips Arua机型,层厚7 mm,螺距1.25 mm,重建间隔5 mm,兴趣区行3 mm薄层扫描。结果:5例CT表现均显示胰头下方肠系膜根部团块状软组织影,可见肠管以系膜血管为中心盘旋状排列呈“漩涡征”,局部小肠系膜纠集,肠管变窄,近段肠管显著扩张。1例在口服造影剂后扫描,可见造影剂从狭窄的肠管内通过。结论:“漩涡征”是本病的CT特征性表现,对“漩涡征”及一些间接征象认识不足,与肠套叠的“靶征”相混淆,是造成误诊的主要原因。Objective To study the CT imagings of volvulus in intestinal malrotation so as to recognize the characteristics of VIM. Methods There were 4 males and 1 female, five cases of VIM proved by surgery were reviewed. Results 5 cases were found intestinal bowel converging toward the root of superior mesenteric artery-whirl sign. Conclusion whirl sign was a characteristic CT finding of VIM.
