【摘要】 目的　研究支气管黏液嵌塞的CT表现 ,以提高对其诊断水平。方法　本组 14例 ,包括肺癌 5例 ,支气管扩张 4例 ,支气管肺曲菌病 3例 ,肺炎和肺结核各 1例。全部病历均有X线胸部平片及常规胸部CT扫描和 10例做了HRCT。结果　CT见支气管黏液嵌塞表现为树枝状占 71 4% ,小棒状 14 3% ,串珠状 14 3%。其显著特点是主轴指向肺门 ,且与支气管走向一致 ,伴有支气管扩张。结论　CT扫描是发现和诊断支气管黏液嵌塞的良好方法更多还原

【Abstract】 Objective To study the CT menifestations of bronchial mucoid impactions to improve diagnostic efficacy. Methods 14 patients with bronchial impaction included lung cancer 5,bronchiectasis 4,pneunonia 1,pulmonary tuberculosis 1,ABPA 3. There were X-ray films,conventional CT in all of patients with bronchial mucoid impactions and HRCT in 10 cases. Results The CT showed mucoid impaction as thick,branching structures resembling branches of tree 71.4%,small clubs 14.3%,multiple spherical shape 14.3%. A prominent feature of bronchial mucoid impaction on CT,in which its axis pointed to the hilum,completely consistent with the branching and distribution of the bronchi,and accompanied by bronchiectasis. Conclusion CT examination is an optinal approach to find out bronchial mucoid impacvtion. [更多还原
