Examples of conditions that were not mistaken as COVID-19. a Pneumocystis jiroveci pneumonia in a 33-year-old man with positive HIV test; axial CT image shows extensive bilateral ground-glass opacities with relative subpleural sparing. b Rhinovirius pneumonia in a 42-year-old woman; axial CT image shows multiple ill-defined patchy areas of GGO with left pulmonary nodules. c A 31-year-old farmer with subacute hypersensitivity pneumonitis; axial CT image shows patchy or diffuse bilateral ground-glass opacities associated with poorly defined centrilobular nodules. d A 66-year-old man with diffuse alveolar hemorrhage; axial CT image shows asymmetric bilateral patchy areas of GGO
