    INPUT: The lungs are clear of focal consolidation . There is however persistent opacity projecting over then lower lungs on the lateral view .

No acute osseous abnormalities identified .
    OUTPUT:
    
No acute cardiopulmonary process . Focal opacity projecting over the posterior lung bases on the lateral view is likely related to destructive mass lesion involving the posterior right rib with adjacent atelectasis .
