(a) Axial CT scans from an above 60 year-old male; Selected cut from non-contrast chest CT of lung window. Sub pleural crescent-shaped Ground-glass opacities as well as smooth interlobular septal thickening can be seen in both lungs, involving mostly peripheral zone; (b) Axial CT scans from an above 60 year-old male; selected image from non-contrast chest CT scans, lung window. Extensive consolidation with can be seen in both lower lobes with air bronchograms; (c) and (d) Axial CT scans from an above 50 year-old male at the level of carina; (C) Day 5 after symptom onset: patchy consolidation affecting the bilateral, peripheral lung parenchyma and (d) Day 7: expansion of consolidation in both lungs, as well as ground glass opacities in right side; (e) Axial CT scans from an above 60 year-old male; selected image from non-contrast chest CT scans, lung window. Mixed consolidation and ground glass opacities can be seen in both lower lobes, right middle lobe and lingula of left upper lobe; (f) and (g) Axial CT scans from an above 50 year-old male; selected image from non-contrast chest CT scans, lung window, (f) Day 3 after symptom onset: ground glass opacities in both lower lobe associated with mal focus of consolidation and (g) Day 7: expansion of consolidation in both lungs, as well as GGO in right middle lobe (black arrow); Mild pleural effusion is seen bilaterally (yellow arrows); (h) Axial CT scans from an above 50-year old female; selected image from non-contrast chest CT scans, lung window. Multiple patchy consolidation in both lower lobe; (i) Axial CT scans from an under 50 year-old male; selected image from non-contrast chest CT scans, lung window. Crazy-paving pattern (GGO with superimposed inter- and intralobular septal thickening) are seen bilaterally; (j) Axial CT scans from an above 50 year-old male; selected image from non-contrast chest CT scans, lung window. Ground-glass opacities affecting the bilateral lung field, reverse halo sign (ground-glass opacity surrounded by denser consolidation of crescentic shape) in left lower lobe (arrow), Pleural effusion is seen bilaterally
