摘　　要：目的:探讨穿孔性和非穿孔性阑尾炎的CT表现,评估CT对其诊断价值。方法:选择经临床证实的24例阑尾炎,根据病理结果将这些病例分为2组:穿孔性阑尾炎组(10例)和非穿孔性阑尾炎组(14例)。分析其CT征象并进行比较。结果:阑尾周围蜂窝组织炎、阑尾壁不连续和阑尾周围积气是穿孔性阑尾炎的直接CT征象,对穿孔性阑尾炎的诊断有很高的特异性(P<0.05)。腹腔脓肿是阑尾炎穿孔局限化表现,而腹膜炎则是弥漫性表现。间接CT征象包括阑尾增厚,壁增厚并强化,常合并腔内积液、粪石,可有肠周积液、淋巴结肿大及邻近肠壁增厚。结论:64层螺旋CT对穿孔性阑尾炎有较高的诊断价值。Objective： To explore the CT features of perforated and non-perforated appendicitis ,and evaluate its diagnostic value. Methods： 24 cases of appendicitis, selected and confirmed by operation and pathology, divided into 2 groups： perforated appendicitis group （10 cases） and non-perforated appendicitis group （14 cases）. The CT signs were Analyzed and compared between the two groups. Results： Cellulitis around appendix, appendiceal wall discontinuity and periappendiceal pneumatosis are direct CT signs of perforated appendicitis, diagnosed with a high specificity （P 〈 0.05）. Abdominal abscess is confined expression of perforative appendicitis, and peritonitis is its diffuse sign. Indirect signs of CT include appendiceal thickening, wall thickening and strengthening, often combined with intracavitary effusions, bezoar, intestinal effusion, lymphadenopathy and adjacent bowel wall thickening. Conclusion： 64-MDCT is of high diagnostic value on perforated appendicitis.
