Fig. 2.

Axial contrast-enhanced CT of the abdomen, lower cuts of the chest lung window demonstrate bilateral patchy consolidative changes and ground-glass opacities with a striking peripheral distribution (black arrows in A). Focal areas of faint interlobular septal thickening at left lower lobe (blue arrows in B). Peripheral rim of consolidation with central ground-glass opacities consistent with reverse halo sign (Atoll sign) at the left lower lobe basal segment (curved red arrow in C). Findings are considered typical CT imaging appearance for SARS-CoV-2 pneumonia.
