FINDINGS:
Compared with prior radiographs on , there is slight increase in
 opacity at the right lung base, may represent scarring or atelectasis, however
 cannot exclude pneumonia in the appropriate clinical setting.  Chronic
 scarring at the left lung base is stable.  No pleural effusion or pneumothorax
 is seen. The cardiac and mediastinal silhouettes are unchanged.  Again seen
 are multiple lytic lesions seen in the proximal left humerus, and myelomatous
 changes of multiple right-sided ribs.

IMPRESSION:
Slight increase in opacity at the right lung base compared with prior, may
 represent chronic scarring or atelectasis, however pneumonia should be
 considered in the appropriate clinical setting.
