    INPUT: Initial radiograph shows the endotracheal tube terminating 6 .5 cm from the carina . The tube was subsequently repositioned and the followup image shows the endotracheal tube terminating 4 .3 cm above the carina in appropriate position . There are bilateral perihilar opacities with a " bat - wing " appearance which likely reflects neurogenic edema versus severe aspiration . The cardiac silhouette is normal . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
1 . Endotracheal tube terminating 4 .3 cm above the carina in appropriate position . 2 . Moderate neurogenic edema and / or severe aspiration .
