    INPUT: A nasogastric tube has been exchanged and can be followed to the diaphragmatic inlet where it may terminate possibly in the distal esophagus . There is a large left - sided pleural effusion . Allowing for suspected differences in orientation , there is no definite change in its size . There is similar mild rightward shift of mediastinal structures and a moderate pleural effusion is probably unchanged on the right . Opacification appears increased in the left lower lung with new total opacification of the superior segment , in addition to a substantial suspected pleural effusion and consolidation or atelectasis of the left lower lobe and lingula .
    OUTPUT:
    
Increasing opacification of the left lower hemithorax reflecting a persistent moderate - to - large pleural effusion and suspected consolidation or atelectasis involving the lingula and left lower lobe , now involving the superior segment .
