    INPUT: Mild to moderate cardiomegaly re - demonstrated , with diffuse calcification and tortuosity of the thoracic aorta . Graft stent within the descending thoracic aorta is in unchanged position . Opacity within the right paramediastinal upper lung is unchanged compatible with known radiation changes for non - small cell lung cancer . No overt pulmonary edema is identified . Moderate right pleural effusion appears relatively unchanged . Left basilar opacification is new , and is compatible with the presence of a small to moderate left pleural effusion and probable adjacent atelectasis . A left basilar infectious process is not excluded . No pneumothorax is identified . No acute osseous abnormalities are seen .
    OUTPUT:
    
Persistent moderate size right pleural effusion . New small to moderate sized left pleural effusion with left basilar opacity either reflecting atelectasis or possibly infection . Unchanged post radiation treatment changes within the right upper paramediastinal lung .
