Figure 13a.
COVID-19 pneumonia with superimposed ARDS in a 61-year-old man who presented to the emergency department with hypoxia and subsequently underwent intubation. (a) AP chest radiograph shows bilateral diffuse lower-lobe predominant opacities (arrows), compatible with COVID pneumonia. (b) Coronal nonenhanced chest CT image shows “crazy-paving” pattern, with diffuse bilateral GGOs, interlobular septal thickening, and intralobular lines, a typical appearance of COVID-19 pneumonia.
