FINDINGS:
Patient is status post median sternotomy.  Right-sided Port-A-Cath tip
 terminates in the upper SVC, unchanged.  Cardiac silhouette remains moderately
 enlarged but unchanged.  Multiple calcified mediastinal lymph nodes are again
 demonstrated suggestive prior granulomatous disease.  The mediastinal and
 hilar contours are otherwise unremarkable.  Lung volumes are persistently low
 with streaky atelectasis seen in the right lung base.  No focal consolidation,
 pleural effusion or pneumothorax is seen.  The pulmonary vasculature is not
 engorged.

IMPRESSION:
Persistently low lung volumes with streaky right basilar atelectasis.
