Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size appears mildly enlarged , unchanged . The aorta is slightly tortuous but similar . Hilar contours are unremarkable . Increased interstitial opacities are noted diffusely , as seen previously , which may be due to mild pulmonary edema , but an atypical infection is not excluded . Blunting of the right costophrenic angle suggests a trace pleural effusion . No focal consolidation , large pleural effusion or pneumothorax is present . Right axillary clips and left breasts clips are again noted . Diffuse osseous metastatic disease is again noted , better assessed on prior CT . Fractures of the left second through fifth lateral ribs appear to be chronic with callus formation .
    OUTPUT:
    
1 . Diffuse osseous metastatic disease , with subacute appearing left lateral second through fifth rib fractures . 2 . Increased interstitial opacities diffusely , as seen previously , which may reflect mild interstitial pulmonary edema , but an atypical infection is not excluded .
