IMPRESSION:
Left lower lobe is still collapsed.  Small left pleural effusion is unchanged.
 Lucency projecting lateral to the aortic knob could be a small
 pneumomediastinum or aeration just beneath the left major fissure. Right lung
 is clear.  No right pleural abnormality.
 
 Course of the nasogastric tube reflects a large hiatus hernia. ET tube in
 standard placement.
