摘　　要：目的:探讨皮肌炎(DM)/多发性肌炎(PM)相关间质性肺病(ILD)的高分辨率CT(HRCT)特征。方法:回顾性分析2014年1月至2019年12月间141例合并ILD的DM/PM患者的胸部HRCT征象。结果:DM/PM-ILD的HRCT表现主要包括:磨玻璃影(87.2%,123/141)、小叶间隔增厚(78.0%,110/141)、小叶内间质增厚(63.8%,90/141)、实变(29.0%,41/141)、胸膜下线(26.2%,37/141)、牵拉性支气管扩张(19.9%,28/141)、蜂窝征(3.5%,5/141);其他合并表现还包括纵隔气肿(3例)、胸腔积液(15例)及心包积液(18例);主要的影像分型为非特异性间质性肺炎(NSIP),其次为机化性肺炎(OP)。结论:尽管DM/PM-ILD病变类型复杂,但其影像学表现仍具有一定的特征性,掌握其HRCT主要特征及影像分型有助于该病的早期识别和及时诊治。Objective:To evaluate high-resolution computed tomography(HRCT)features of dermatomyositis-/polymyositisassociated interstitial lung disease(DM/PM-ILD).Methods:We retrospectively reviewed the HRCT images of 148 patients with DM/PM-ILD at the First Affiliated Hospital of Xi’an Jiaotong University between Jan.1,2014,and Dec.31,2019.Results:The HRCT features of DM/PM-ILD were characterized by ground-glass opacities(GGO)(87.2%,123/141),interlobular septal thickening(78.0%,110/141),intralobular interstitial thickening(63.8%,90/141),consolidation(29.1%,41/141),subpleural lines(26.2%,37/141),traction bronchiectasis(19.9%,28/141),and honeycombing(3.5%,5/141).Pneumomediastinum(3),pleural effusion(15),and pericardial effusion(18)were also observed.The two main radiological patterns were non-specific interstitial pneumonia(NSIP)and organism pneumonia(OP).Conclusion:HRCT features of DM/PM-ILD are heterogeneous,with various radiological patterns.Mastering the main characteristics of HRCT manifestation and the radiological patterns of DM/PM-ILD will be helpful for early identification and timely treatment.
