    INPUT: As compared to prior chest examinations , there is increased opacity extending throughout the left lung with minimal aerated lung , likely due to tumor progression . There is overlying pleural effusion and atelectasis . Scattered reticular opacities in the right lung could reflect metastatic disease . Evaluation of the cardiac silhouette is limited . The trachea is midline . There is no pneumothorax .
    OUTPUT:
    
Increased opacity extending throughout the left lung with minimal lung aeration likely reflects tumor progression with overlying pleural effusion and atelectasis . Reticular opacities in the right lung could reflect metastatic disease . Further evaluation with a chest CT is recommended .
