Radiological findings over time. A, B CT on admission revealed bilateral ground opacities superimposed with a subpleural reticular shadow and honeycombing. Multiple nodular lesions were detected in the bilateral lung fields and liver. C, D Re-examination of CT before intubation on the 4th hospital day showing the deterioration of opacities along with traction bronchiectasis. Pulmonary and liver nodules slightly increased in size. E, F On the 12th hospital day after weaning from the mechanical ventilator, diffuse ground-glass opacities improved and pulmonary and liver nodules decreased in size. G, H On the 21st hospital day before re-intubation, the interstitial shadow was exacerbated and the sizes of pulmonary nodules increased. Liver nodules showed no significant changes in size. Mediastinal emphysema was detected
