CTICasesViral Bronchopneumonia due to Human Metapneumovirus
Imaging findings
CT shows diffusely thickened bronchial walls with adjacent areas of tree-in-bud opacity and consolidation, a pattern of viral bronchitis and bronchopneumonia.
Key takeaways
PCR confirmed human metapneumovirus, and the findings were considered absolutely typical for viral bronchopneumonia from this organism, forming a companion case to a previously presented metapneumovirus case, reinforcing the characteristic bronchial-wall-thickening and tree-in-bud pattern of viral airway infection.
