Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with chest radiograph on ___ , overall lung volumes are decreased . A right lower and middle lung opacity slightly worse compared with prior . There is a new opacity at the left lung base , likely atelectasis . Pulmonary vascular congestion is slightly decreased compared with prior , but remains mild . A right pleural effusion is similar to prior . There is no pneumothorax . Cardiomediastinal silhouette is unchanged .
    OUTPUT:
    
1 . Interval worsening of a right mid and lower lung consolidation is concerning for evolving pneumonia and less likely represents asymmetric pulmonary edema given the interval slight improvement in pulmonary vascular congestion compared with prior . Small right pleural effusion is similar to prior . 2 . New opacity at the left lung base likely reflects atelectasis .
