    INPUT: Patchy opacity at the right base has increased , concerning for progressive pneumonic infiltrate . No air bronchograms are identified and there is probably some associated volume loss . Possible minimal blunting of the right costophrenic angle , without gross effusion . Again seen is some patchy opacity at the left base , overall similar in degree to the prior study . There is upper zone redistribution and mild vascular plethora , without other evidence of CHF . No focal opacities are seen in the upper or mid zones in either lung . The cardiomediastinal silhouette is similar . The pulmonary hila are again noted to be slightly prominent . Enteric type tube present , with short radiopaque tip lying in the region of the GE junction . The previously seen Dobhoff tube is no longer visualized . Dual - lumen right - sided catheter , with tips overlying the distal SVC and cavoatrial junction , appears to be new / exchanged compared with the prior study . No pneumothorax detected .
    OUTPUT:
    
1 . Progressive opacity at the right base is concerning for a pneumonic infiltrate . 2 . Patchy opacity at the left base is not significantly changed . The differential diagnosis includes atelectasis or possibly an early pneumonic infiltrate .
