    INPUT: Compared to the prior study , the ET tube and NG tube have been removed . The presumed epidural catheter is no longer visualized . There is a new moderate - sized right effusion with underlying collapse and / or consolidation . There is increased retrocardiac density with patchy opacity at the left base , similar to the prior film , but slightly more pronounced . There is blunting of left costophrenic angle which is new , consistent with a small left effusion . There is upper zone redistribution , without other evidence of CHF . Heart size is borderline enlarged but may be unchanged allowing for considerable technical differences . Aorta is calcified . No pneumothorax detected .
    OUTPUT:
    
New small to moderate size right effusion with underlying collapse and / or consolidation . This is a significant change compared with ___ , as there was no right effusion or right base opacity on the prior film . Patchy left base opacity probable slightly increased , with new small left effusion . Upper zone redistribution . Doubt overt CHF .
