皮肌炎/多发性肌炎相关间质性肺病高分辨率CT特征

HRCT Features of Dermatomyositis-/Polymyositis- Associated Interstitial Lung Disease

  • 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。

     

    Abstract: Objective: To evaluate high-resolution computed tomography (HRCT) features of dermatomyositis-/polymyositis- associated 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.
