    INPUT: Left internal jugular central venous catheter tip course may be intra-arterial given its position overlying the inferior aspect of the aortic knob and does not course in the expected region of the left brachiocephalic vein . No pneumothorax is demonstrated . The endotracheal tube remains low lying , terminating approximately 2 .5 cm from the carina . An enteric tube is within the stomach . The cardiac and mediastinal contours are unchanged with the heart size remaining mild to moderately enlarged . Mild upper zone vascular redistribution is likely due to supine positioning . Atelectasis is demonstrated in both lung bases . No large pleural effusion or pneumothorax is identified on this supine exam . No displaced fractures are apparent .
    OUTPUT:
    
1 . Left internal jugular central venous catheter course is concerning for intra-arterial location . Clinical correlation is recommended . No pneumothorax . 2 . Endotracheal tube remains low lying , terminating approximately 2 .5 cm from the carina , and should be withdrawn by at least 1 cm .
