急性闌尾炎的多層螺旋CT表現與診斷探討

Diagnostic value of multi-slice spiral CT for acute appendicitis

目的探討多層螺旋CT對急性闌尾炎的診斷價值。方法經手術及病理證實的11例急性闌尾炎的CT表現進行回顧性分析。結果闌尾腫大增粗11例(100%),闌尾壁明顯強化(9例增強掃描病患中7例有明顯強化,約78%,另2例只做了平掃),腔内積液(11例中9例,約82%,其中1例見積氣及積液並液平),闌尾石(11例中5例,約45%,其中1例見兩處闌尾石),闌尾邊緣模糊及闌尾周圍結締組織及脂肪層密度增高(11例中10例,約91%),闌尾周圍膿腫(11例中4例,約36%),局部淋巴結腫大(11例中5例,約45%)。結論螺旋CT是診斷急性闌尾炎的有效手段。

Objective To investigate the diagnostic value of MSCT in acute appendicitis.Methods The CT findings of 11 patients with acute appendicitis proved by surgical pathology were analyzed retrospectively.Results On CT images,appendiceal swelling and thickening were found in all 11 cases(100%),remarkable enhancement of appendiceal wall in 7 of 9 cases(78%),collection,including only or both air and fluid collection,in the lumen in 9 cases(82%),appendolith in 5 of 11 cases(45%),periappendicitis in 10 of 11(91%),Appendiceal abscess in 4 of 11(36%),lymphoadenopathy in 5 of 11(45%).Conclusion Spiral CT is an effective means in diagnosis of acute appendicitis.
