Imaging findings
The patient shows mild bronchial wall thickening and indistinct, busy-appearing bronchovascular bundles. CT scans reveal subtle, excessive centrilobular dots and basal lung opacities, which are likely secondary to aspiration of secretions.
Key takeaways
Viral infections can lead to secondary aspiration of sinus secretions, particularly in the lung bases. This case illustrates a mild bronchitis/bronchiolitis presentation of H5N1.
