摘　　要：目的:探讨脓肿型分支杆菌病的胸部X线和CT影像学表现。方法:回顾性分析18例经临床确诊为脓肿型分枝杆菌感染患者的X线、CT表现。结果:胸片异常征象:斑点状、细网状阴影16例(89%,16/18),空洞8例(44%,8/18),肺叶体积缩小8例(44%,8/18),实变4例(22%,4/18),支气管扩张8例(44%,8/18)。CT异常征象:支气管扩张12例(66.7%,12/18),其中表现为柱状支气管扩张9例(50%,9/18),囊状支气管扩张5例(27.8%,5/18),静脉曲张型支气管扩张3例(16.7%,3/18);直径小于10mm结节17例(94.4%,17/18),树丫征15例(83.3%,15/18);直径大于10mm结节13例(72.2%,13/18),肺叶实变6例(33.3%,6/18),段或亚段实变9例(50%,9/18),空洞9例(50%,9/18),肺体积缩小7例(38.9%,7/18)。结论:脓肿型分枝杆菌感染的胸片和CT表现主要为小结节样斑片状、细网状影、支气管扩张和空洞形成。Objective：To investigate the radiographic and computed tomographic（CT） findings of patients with pulmonary mycobacterium abscessus infection.Methods：Between January 2009 and December 2010,the radiographic and thin section chest CT images and histopathologic lung tissue specimens from 18 patients with pulmonary infection caused by mycobacterium abscessus were restrospectively reviewed.Results：The radiographic findings were reticulonodular opacities（89%,16/18）,cavity（44%,8/18）,lobar volume loss（44%,8/18）,consolidation（22%,4/18） and bronchiectasis（44%,8/18）.Thin section CT findings were bronchiectasis（12/18,66.7%）,nodules less than 10mm（17/18,94.4%）,tree in bud sign（15/18,83.3%）,nodules larger than 10mm（13/18,72.2%）,lobular consolidation（6/18,33.3%）,segmental and subsegmental consolidation（9/18,50%）,cavity（9/18,50%）,cylindric bronchiectasis（9/18,50%）,cystic bronchiectasis（5/18,27.8%）,varicose bronchiectasis（3/18,16.7%） and volume loss（7/18,38.9%）.Conclusion：The main radiologic and CT manifestations of mycobacterium abscessus lung infection are bilateral small nodular opacities,bronchiectasis,and cavity formation.
