Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lateral view , particularly along the anterior chest , is partly obscured because the arms are down . There are widespread patchy opacities but with fairly focal involvement of the right lower lung . These opacities are seen in the context of a mild diffuse interstitial abnormality suggesting slight vascular congestion or fluid overload . It is difficult to exclude very small effusions , but no definite pleural effusions are demonstrated .
    OUTPUT:
    
Multifocal opacities , most confluent in the right lower lung , concerning for pneumonia ; findings suggestive of slight vascular congestion or fluid overload as well .
