A, B, COVID-19 and organizing pneumonia (OP). A 55-year-old man had confirmed COVID-19 with a typical imaging appearance on CT scans. Axial unenhanced CT scan images through the middle (A) and lower (B) lung zones show ground-glass opacification (GGO) with intralobular septal thickening in the right upper lobe and GGO and consolidative opacities in the periphery of each lower lobe, with a perilobular pattern in the left lower lobe. These findings are also typical of OP.
