Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to ___ , the lung volumes are lower without discrete atelectasis . The low lung volumes exaggerate the heart size , pulmonary vasculature , and caliber of the mediastinal veins , all of which are probably normal . There are no consolidations or pleural abnormalities . The pathological fracture of the sternum appears more pronounced than on the prior radiograph , which may be a function of the low lung volumes , and should be evaluated clinically to assess for stability . Multiple lytic lesions are again seen within the clavicles .
    OUTPUT:
    
1 . No evidence of pneumonia . 2 . Pathologic fracture of the sternum appears more prominent which may be related to low lung volumes . This can be assessed clinically for stability .
