超声与CT诊断原发性肠脂垂炎的比较

The ultrasound and CT in diagnosis of primary epiploic appendagitis

目的:分析原发性肠脂垂炎(PEA)的超声和CT影像特点,比较两者的诊断价值。方法:36例PEA中,男30例,女6例。所有病例均行超声和CT检查,比较两者诊断符合率。结果:PEA超声特点表现为结肠壁旁卵圆形、不可压缩的高回声团块,且与腹壁有粘连;CT特征表现为结肠壁旁"戒指"样或卵圆形脂肪性密度。超声诊断PEA符合率为88.9%,CT诊断符合率为91.7%,两者差异无统计学意义(2=0.06,P>0.10)。结论:超声诊断PEA是首选影像学检查手段,CT可作为补充。

Objective：To evaluate the features of both ultrasonography and CT in the diagnosis of primary epiploic appendagitis（PEA）.Methods：36 cases of PEA were confirmed by pathology（10 cases） and clinical diagnosis（26 cases）.All patients underwent both ultrasound and CT examinations in order to compare their diagnostic value.Results：PEA ultrasonographic characteristics reflected an egg round high echo mass of incompressible and adhesion with abdominal around the colon.CT feature of PEA was like-ring or egg circula,fatty density around the colon.The diagnostic coincidence rates of PEA were 88.90%（32/36） and 91.7%（33/36） for ultrasonography and CT with no significant difference between them 2=0.06,P0.10）.Conclusion：Ultrasonography may be the first choice for diagnosing or follow-up PEA,while CT is a supplement.
