    INPUT: The endotracheal tube terminates approximately 6 cm above the carina . Port - A - Cath terminates in the lower SVC . The enteric tube is below the diaphragm however the tip is not visualized . An esophageal stent is again noted . Extensive interval development of asymmetric opacification of the right mid to lower lung and to a lesser extent patchy opacification of the left lower lung could represent infectious or aspiration pneumonia . There is no pulmonary edema . A small right pleural effusion is possible . No pneumothorax .
    OUTPUT:
