FINDINGS:
Heart size remains mildly enlarged.  Aortic knob is densely calcified.  The
 mediastinal contour is unchanged.  Right hilar opacity is similar to the
 previous examinations.  Rounded opacity projecting over the right mid lung
 field likely reflects fluid loculated within the major fissure. A moderate
 right pleural effusion and trace left pleural effusion are noted, and there is
 mild pulmonary edema.  Patchy opacity in the lung bases may reflect
 atelectasis but infection or aspiration is not excluded.  No pneumothorax is
 present.  Emphysematous changes are again seen in the lungs.

IMPRESSION:
1. Mild pulmonary edema and moderate size right and small left pleural
 effusions.  Small amount of fluid is loculated within the right major fissure.
 2. Patchy opacity in the lung bases may reflect atelectasis but infection or
 aspiration cannot be excluded.
 3. Unchanged chronic right hilar opacity.
