Typical coronavirus disease 2019 (COVID-19) case classified as positive with all three sets of reporting systems. Axial chest computed tomography images of a 77-year-old woman with COVID-19 obtained 5 days after the onset of symptoms show bilateral, peripheral multifocal ground-glass opacity. Crazy-paving appearance was found in the left lung. Our majority classification was CO-RADS 5, COVID-RADS 3, and typical for pneumonia in the RSNA expert consensus statement (true positive).
