Fig. 9B. —34-year-old man with severe acute respiratory syndrome
coronavirus pneumonia. He presented with fever, cough, and malaise.
High-resolution CT scans obtained on day 20 show diffuse ground-glass
attenuation and consolidations (arrows) associated with traction
bronchiectasis and bronchiolectasis. Honeycomb changes (arrowheads)
are found in subpleural area of left and right lower lobes posteriorly.
Architectural distortion is observed from displacement of bronchi and pulling
back of major fissures. There is no pneumomediastinum. Patient also had
cardiomegaly with pulmonary arterial hypertension. Pulmonary trunk measured
