AP and lateral views of the chest are compared to previous exam
 from .  Postoperative changes of left upper lobectomy are again

 pneumothorax.  Slightly increased linear right basilar opacity is seen. 
 Elsewhere, the lungs are hyperinflated but clear of confluent consolidation. 
 Cardiomediastinal silhouette is stable as are the osseous and soft tissue
 structures.

 infection is not completely excluded.  Stable postoperative changes of left
 upper lobectomy.
