FINDINGS:
Heterogeneous opacities overlying the left mid lung field and
 silhouetting the left heart border are increased since .  The
 patient is status post left lower lobectomy for volume reduction with stable
 mild leftward shift of the mediastinum.  Blunting of the left costophrenic
 angle is compatible with a small pleural effusion.  The right lung is grossly
 clear.  No pneumothorax.  The heart size appears normal.  No radiopaque
 foreign body.

IMPRESSION:
Increased lingular and left lower lung opacities, compatible with
 worsened infection since .  Small left pleural effusion.
