Evolution of ARDS at chest X-ray (post-infective ARDS). Latent period: no pathologic findings (a). The following day appearance of bilateral patchy consolidations, with bilateral pleural effusion (b). HRCT, performed on the same day, shows bilateral patchy and lobular GGOs and consolidations, randomly distributed (atypical ARDS) (c). The day after, chest X-ray shows bilateral extensive opacification (“lung white-out”) (d). Parenchymal opacification remains stable: chest X-ray 2 days later (e). The patient survived and improved quickly: marked radiographic improvement 7 days later (f)
