In this study, the imaging features were consistent with the previous literature reports [9–13, 16–18] of viral pneumonia; most of the patients had ground-glass opacities and mixed ground-glass opacities; no patients demonstrated consolidation without ground-glass opacification. Subpleural distribution was common. It also occurred around the bronchovascular bundle. Air bronchograms and interlobular septal thickening were often present. No patients had cavitation, centrilobular nodules, and lymphadenopathy. Pleural effusion was rare and most of them occurred in severe cases. Most of the lesions involved both lower lobes (85.7%), most of them more than two lobes (74%), and bilateral involvement was common (83.3%); single lobe involvement was rare (10.3%).
