Table 4 Differential diagnosis of different viral pneumonia
Virus Imaging characteristics
MERS-COV Ground glass lesions in the subpleural and basal portions of the lung parenchyma with areas of consolidation; fibrotic changes can be present after healing
H1N1 Ground glass opacity, interlobular septal thickening, and centrilobular nodules
H7N9 Ground glass opacity and consolidation with air bronchograms and interlobular septal thickening
Human parainfluenza virus Centrilobular nodules with bronchial wall thickening, findings which differentiate it from other viral infections
Respiratory syncytial virus Small centrilobular nodules and areas of parenchymal consolidation; asymmetrically distributed in the lungs
Adenovirus pneumonia Bilateral multifocal ground glass opacities, patchy consolidation in a lobar and/or segmental distribution
