    INPUT: Patient is rotated somewhat to the right . Overall , the appearance of the right chest is similar to prior . Large area of right perihilar , right upper to right mid lung opacity with mass like opacity at the level of the right hilum , grossly stable . There is again seen a volume loss of the right lower lung . There appears to be subtle increase in now left perihilar and left infrahilar / basilar streaky opacity which may relate to volume overload however , infectious process , aspiration , or other disease spread not excluded . No large pleural effusion is seen on the left although a trace left pleural effusion be difficult to exclude . There is no pneumothorax . The cardiac and mediastinal silhouettes are grossly stable given that the right aspect is obscured by right hemithorax opacity .
    OUTPUT:
