Figure 1 Representative high-resolution computed tomography (HRCT) images for rapidly progressive interstitial lung disease (RP-ILD) in patients with anti-melanoma differentiation-associated protein 5-positive dermatomyositis (MDA5+ DM). (Image A and B were from the same patient, and image C and D were from another patient). (A, C) HRCT images when ILD was first diagnosed. (B) Rapidly aggravated ground-glass opacity (upper right) and reticular patterns (subpleural area) within 3 months compared to image A. (D) Rapidly aggravated consolidation within 3 months compared to image B (orange arrows). (Created by RStudio software, version 4.2.0.).
