    INPUT: There is mild pulmonary vascular congestion . There is a new opacity at the right lung base which may be asymmetric vascular congestion versus pneumonia in the appropriate clinical setting . Significantly increased size of the cardiac silhouette may partly be due to AP , supine , and lordotic positioning and cardiomegaly in the setting of heart failure however a pericardial effusion may be considered in the appropriate clinical setting . There are small bilateral pleural effusions . There is no pneumothorax .
    OUTPUT:
    
1 . Enlarged cardiac silhouette may be partially due to positioning and cardiomegaly in the setting of heart failure however pericardial effusion may be considered in the appropriate clinical setting . 2 . New opacity at the right lung base may be asymmetric vascular congestion versus a pneumonia in the appropriate clinical setting .
