    INPUT: Single frontal view of the chest demonstrates ET tube terminating approximately 4 cm above the carina . An enteric tube courses inferiorly out of view , into the stomach . The heart is normal in size . There is a large right hilar mass measuring at least 6 .5 x 5 .3 cm with plate like perifissural opacity in the right upper lobe , suggestive of post obstructive volume loss . Alternatively , supervening infection and or aspiration can not be excluded in the appropriate clinical setting . Trace left basilar atelectasis is present . There is no pneumothorax or pleural effusion . No displaced osseous injury is evident .
    OUTPUT:
    
1 . Satisfactory ET tube positioning without pneumothorax . 2 . Findings suggest a large right hilar pulmonary mass causing post obstructive atelectasis . Supervening infection and or aspiration can not be excluded in the appropriate clinical setting . Recommend correlation with prior imaging once available .
