    INPUT: There is marked new bilateral upper lobe opacification with volume loss and new small pleural effusion on the right and moderate pleural effusion on the left , with accompanying retrocardiac opacity . Bilateral perihilar fullness suggests coinciding fluid overload , but widespread pneumonia could be considered . The cardiac , mediastinal and hilar contours appear unchanged .
    OUTPUT:
    
New widespread opacification in the upper lungs suggesting either multifocal pneumonia or perhaps an atypical pattern of congestive heart failure . Findings include substantially increased bilateral pleural effusions with retrocardiac opacification , which is non-specific , atelectasis versus pneumonia .
