(a), (b) Chest X-ray and CT on admission showed bilateral central opacities, which are more confluent in the right upper and lower lung zone than elsewhere. There is slight cardiomegaly. (c) The radiograph obtained after intubation on the 10th day showed increased confluence of the opacities. The right hemidiaphragm is partially obscured. (d) Chest CT scan on the 10th day showed bilateral ground-glass opacities corresponding to the central and perihilar opacities and both small pleural effusions. (e) Chest CT scan on the 36th day showed progressed bilateral ground-glass opacities, confluent, and consolidated opacities, and a large quantity of pleural effusions in both lung fields. (f) Chest X-ray on the 92nd day showed the disappearance of infiltrative shadows in both lung fields.
