FINDINGS:
Linear opacities of the lung bases bilaterally likely reflect atelectasis. 
 Hyperlucency of the upper zones is reflective of emphysema.  No focal
 consolidation, pleural effusion, or pneumothorax.  Heart size and mediastinal
 contours are normal.  Osseous structures are demineralized diffusely with a
 compression deformity in the mid thoracic spine which is unchanged from .

IMPRESSION:
Emphysema and bibasilar atelectasis.  No evidence of pneumonia.
