case_images: Initial chest radiograph showed patchy peripheral opacities predominantly in the bilateral midlung fields (Figure 1).
case_images: Axial contrast-enhanced chest CT in lung window showing bilateral peripheral ground-glass opacities.

case_images: Chest CT revealed bilateral, multifocal, and peripheral ground-glass opacities consistent with known COVID-19 infection (Figure 2).
case_images: (a) Obliqued axial image demonstrating two adjacent target lesions, labelled "x" marked by the red arrow, and "y" marked by the yellow arrow. Lesion "a" clearly demonstrates a "central dot" (small green arrow) which corresponds to a pulmonary artery branch. (b) Oblique sagittal image through lesion "x" (red arrow) depicting the "central dot" or small pulmonary artery branch (small green arrow).

case_images: In addition, two "target" lesions were also identified demonstrating nodular central opacities surrounded by a ground-glass halo, then a ring of relative lucency which in turn was surrounded by a ring of peripheral ground-glass opacity or consolidation (Figures 3 and 4).
case_images: (a) Axial image at a level superior to Figure 3(a) depicting target lesion "y" (yellow arrow). The small green arrow shows the prominent central vessel. Oblique coronal (b) and sagittal (c) images through lesion "y" (yellow arrow), also showing prominent central vessels (small green arrows).
