摘要
目的探讨64排螺旋CT对成人肠套叠的诊断价值。方法收集我院2012年1月至2013年12月经手术病理证实的13例成人肠套叠,并对其CT平扫及7例增强表现进行回顾性分析。结果 13例中均可见套叠头体部呈现分层鞘状软组织影,其中8例见"靶征",2例见"腊肠征",2例见"肾形",1例见不规则肿块改变;7例增强扫描时可见肠壁的各种形态改变,诸如有无缺血水肿、坏死,并判定血管并发症的严重程度等征象。结论 CT平扫及增强扫描对成人肠套叠的定性及定位诊断有重要的价值。
Objective To discuss the CT findings of adult intussusception （AI） and to evaluate their value for the diagnosis. Methods Thirteen patients with surgically or clinically proved AI were collected from January 2012 to December 2013 in our hospital. All patients underwent plain CT scans of the abdomen, of whom 7 patients underwent additional contrast-enhanced CT scans. The CT findings of all patients were analyzed retrospectively. Results CT scans demonstrated that 13 cases had layering target masses which comprised ＆quot;target sign＆quot; in 8 cases and ＆quot;sausage-like shadow＆quot;in 2 case, ＆quot;reniform sign＆quot; in 2 cases, ＆quot;anomaly masses＆quot; in 1 case. Contrast-enhanced CT scans in 7 cases could clearly show varied morphologic changes of the affected bowel walls such as the presence or absence of ischemia, edema, and necrosis and could also identify the severity of the vascular complications. Conclusion Plain and contrast-enhanced CT scanning has high value for diagnosing adult intussusception.
