IMPRESSION:
Comparison to , 22:04.  The lung volumes have slightly
 decreased.  Mild atelectasis at the left lung bases.  Of the chest tube
 removal on the right there is no radiographic evidence for the presence of a
 pneumothorax.  Normal size of the heart.  Mild elongation of the descending
 aorta.  A minimal bilateral pleural effusion, restricted to the posterior
 costophrenic sinus, is better visualized on the lateral than on the frontal
 image.
