Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac , mediastinal and hilar contours are unchanged , with the heart size within normal limits . Pulmonary vascularity is not engorged . Left upper lobe mass is redemonstrated , and right upper lobe ill - defined opacity appears relatively unchanged compared to prior chest CT , but is more pronounced when compared to the prior chest radiograph . Emphysematous changes are again noted . No pleural effusion or pneumothorax is present . There are no acute osseous abnormalities .
    OUTPUT:
    
Unchanged left upper lobe mass compatible with known cancer , with ill - defined opacity in the right upper lobe likely corresponding to the subpleural opacities seen on prior chest CT . This finding , however , appears more pronounced when compared to the prior chest radiograph . No new abnormality otherwise identified .
