Figure 4. Axial CT through lung bases of a male patient (lung parenchymal window level settings).

A 45-year-old male patient presented with cough, fever, and progressive shortness of breath while self-isolating. His respiratory function deteriorated and he was admitted to the hospital. A chest CT was performed, which showed evidence of COVID-19 and subsequent RT-PCR was positive. An axial contrast-enhanced CT image of the chest showed bilateral patchy ground-glass and consolidative changes with areas of confluence. There was a linear air bronchogram seen in the right upper lobe (black arrows). This was surrounded by peri-bronchial consolidation and ground-glass changes
