FINDINGS:
The lungs are reasonably well expanded, with only trace atelectasis in the
 left lung base.  There is no pleural effusion, pulmonary edema, pneumothorax,
 or consolidation concerning for pneumonia.  The cardiomediastinal silhouette
 is unremarkable.  There is mild bronchial wall thickening, which appears to
 wax and wane on prior studies.

IMPRESSION:
No evidence of pneumonia.  Mild bronchial wall thickening could reflect
 bronchitis.
