(A,B) A patient with ICI pneumonitis. Although ground glass opacities are present (A), consolidations outside the areas of ground glass opacities are the dominant feature (B), corresponding to a pattern of organizing pneumonia. (C,D) Two cases of RT-PCR proven COVID-19. One patient with typical well-demarcated slightly rounded subpleural ground glass opacities with thickened inter- and intralobular septa within this area (crazy paving): CO-RADS 5 (C). The second patient shows well-demarcated, but not rounded, bilateral subpleural ground glass opacities with early thickening inter- and intralobular septa (D). During the COVID-19 pandemic this case was judged as very highly suspicious (CO-RADS 5), but this case lacks confirmatory features.
