FINDINGS:
Lung volumes are low.  The cardiomediastinal silhouette is unremarkable. 
 Known right-sided rib fractures are not well visualized on the current
 examination.  There is progressive lingular and right basilar opacity since , also progressed since the most recent comparison.  Small pleural
 effusions are stable.  Improved pulmonary vascular congestion.

IMPRESSION:
Progressive right basilar opacity may represent atelectasis or developing
 infectious pneumonia.  Left lower lobe opacity has slightly improved and
 previously reported volume overload has nearly resolved.
