CHF with interstitial 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. The presence of Kerley lines are pathognomonic of interstitial infiltrates. This patient presents with typical Kerley B lines: thin horizontal lines stacking above the CP angle on frontal view.
