Patient with severe, lung damage from COVID. Images in a 54-year-old man with COVID-19–related acute respiratory distress syndrome and subsequent fibrosis. (A) Axial CT 2 weeks after admission shows diffuse ground-glass opacity (GGO) with reticular abnormality and traction bronchiectasis in right middle lobe, indicating organizing phase of lung injury. (B) Axial CT 6 months after admission shows decreased GGO but extensive traction bronchiectasis and architectural distortion, suggesting fibrosis. RSNA
