Transverse unenhanced thin-section serial CT scans from a 64-year-old female with suspected COVID-19 pneumonia. Chest CT images on the second day after symptom onset found minimal ground-glass opacities with partially rounded consolidation in the apexes of both lungs (A1), and multiple ill-defined patchy ground-glass opacities in the middle lobe of right lung (A2). Follow-up CT on the fifth day demonstrated no obvious change of lung lesions (B1, B2).
