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.
