Answer

With avian influenza, pulmonary infiltrates are seen in almost all patients. The widely varied radiographic characteristics range from diffuse or patchy infiltrates to lobar multilobar consolidation. Effusions and lymphadenopathy are also observed, as well as cystic changes.

In avian influenza, the severity of radiologically apparent disease is a good predictor of mortality, including findings consistent with ARDS, such as a diffuse, bilateral ground-glass appearance.
