FINDINGS:
The heart is at the upper limits of normal size.  The mediastinal
 and hilar contours appear unchanged.  There is mild interstitial abnormality
 suggestive of slight fluid overload, but no focal consolidation.  The lungs
 are hyperinflated.  There is no pleural effusion or pneumothorax.  A moderate
 anterior wedge compression deformity situated along the lower thoracic spine
 appears unchanged since the prior studies.

IMPRESSION:
Similar mild interstitial abnormality which could be seen with
 slight fluid overload.
