case_images: Radiological findings in a critically ill 79-year-old Japanese man with COVID-19. A, Chest radiograph obtained on the day of admission showing bilateral ground-glass opacity (GGO) without an air bronchogram. B, On the 13th hospital day, consolidation was visible in the left lower lung, in addition to bilateral GGO. C, D, Chest computed tomography scan obtained 7 days before admission to our hospital showing bilateral faint GGOs. E, F, On the day of admission to our hospital, the lesions had changed to a mixed pattern of GGOs and consolidation. G, H, On the 13th hospital day, the lesions progressed to a consolidation pattern.

case_images: A chest computed tomography (CT) revealed small bilateral ground-glass opacities (GGOs) (Fig. 1C, D) in both lungs. Chest CT and radiography revealed worsening of lesions, illustrated by a mix of GGO and consolidation patterns (Fig. 1A, E, F). The chest CT on the 13th day revealed worsening of the consolidation pattern (Fig. 1B, G, H).
case_images: Course of ventilatory settings and PaO2/FiO2 ratio in a critically ill 79-year-old Japanese man with COVID-19. Light gray shading indicates prone ventilation values over time. Dark gray shading indicates a tidal volume between 6 and 8 mL/kg. Although PaO2/FiO2 improved during prone ventilation, it deteriorated following return to the supine position. Tidal volume was maintained between 6 and 8 mL/kg (predicted body weight). PEEP, positive end-expiratory pressure.
