| 摘 要： | 目的 探讨急性阑尾炎的CT表现。方法 对68例手术、病理证实为急性阑尾炎病人的腹部CT资料进行回顾性分析，对阑尾大小、有无阑尾结石、阑尾周围及盲肠末端的改变作了观察、分析。结果 68例中61例CT诊断为急性阑尾炎，7例假阴性，CT诊断急性阑尾炎的敏感性为89．7％。急性阑尾炎的CT表现主要有阑尾增粗(76．5％)，阑尾结石(29．4％)，阑尾周围炎性改变(66．2％)，阑尾脓肿(13．2％)，蜂窝织炎(10．3％)，盲肠末端肠壁增厚(7．4％)和局部淋巴结肿大(5．9％)。结论 急性阑尾炎可出现多种CT表现，熟悉这些表现有助于提高CT诊断阑尾炎的准确性。

| Abstract: | Objective To investigate CT findings of acute appendicitis.Methods CT images of 68 patients with acute appendicitis proven pathologically were analyzed retrospectively. The size of an appendix, appendolith, periappendiceal and cecal apical changes were observed and noted. Results Sixty-one of 68 patients were correctly diagnosed as acute appendicitis and 7 false-negative. The sensitivity of CT was 89.7%. The most common CT findings of acute appendicitis were an enlarged appendix (76.5%), appendolith (29.4%), periappendiceal inflammatory changes (66.2%),appendiceal abscess ( 13.2%), phlegmon (10.3%), cecal apical thickening (7.4%) and adenopathy (5.9%). Conclusion Acute appendicitis had a variety of CT signs, and understanding of these signs was helpful to improve the diagnostic accuracy of CT. |
