    INPUT: Cardiomegaly is moderate and limits assessment of the retrocardiac lungs . Prominence of the upper mediastinum is likely a combination of unfolding of the aorta and projection . The hila are likely prominent with a tapered appearance raising the question of pulmonary hypertension . There is pulmonary edema , with vascular plethora I interstitial and possible areas of alveolar edema . More confluent opacity seen at the right lung base . There is also row increased retrocardiac density consistent with left lower lobe collapse and / or consolidation . Allowing for positioning , no gross effusions identified .
    OUTPUT:
    
Cardiomegaly and CHF with interstitial and alveolar edema . Left lower lobe collapse and / or consolidation . Possibility of an underlying pneumonic infiltrate can not be excluded .
