CHF with alveolar edema

Findings
-CHF frequently presents radiologically with cardiomegaly and/or pleural effusions. The effusions may be bilateral. When unilateral, the right side predominates. The lung fields may be affected: early CHF results in upper zone redistribution; worsening CHF causes interstitial edema; further progression results in alveolar edema. Air bronchograms in fluffy coalescent infiltrates are pathognomonic for alveolar infiltrates. This patient presents with symmetric bilateral perihilar/batwing alveolar infiltrates typical for CHF with alveolar edema.
