Chest and abdominal plain CT scans in a 68-year-old woman with COVID-19 pneumonia and acute csholecystitis. a, b. Transverse chest CT scan obtained on the first day after admission shows multifocal peripheral GGOs in the dorsal (a) and posterior basal (b) segments of the right lower lobe. c, d. Follow-up chest CT scan obtained on day 3 after admission shows progression of the GGOs. e, f. Follow-up chest CT scan obtained on day 13 after admission shows that the GGOs were partly resolved in the dorsal segment of the right lower lobe (e) and completely resolved in the posterior basal segment of the right lower lobe (f). g. Coronal MPR of the plain abdominal CT obtained on day 11 shows a distended gallbladder, hyperplasia of the gallbladder wall, biliary sludge (arrow), and no gallstones in the gallbladder. h. Coronal MPR of the plain abdominal CT obtained on day 13 shows shrinkage of the gallbladder or its change in shape, a high-density drainage tube and a little bleeding in the gallbladder. CT = computer tomography, GGOs = ground-glass opacities, MPR = multiplanar reconstruction
