Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , consistent with restrictive physiology in this patient with diffuse fibrotic lung disease . Peripheral and basilar predominant pulmonary fibrosis appear similar to the prior radiograph , and has been more fully characterized on CT of ___ . A more confluent area of opacity is present posteriorly overlying the mid - to - lower thoracic spine and corresponds to a left infrahilar mass on prior CT . Based upon comparison of the scout radiograph with the scout from the prior CT scan , the mass appears to have enlarged since ___ . Cardiomediastinal contours are stable in appearance in this patient status post previous median sternotomy and coronary artery bypass surgery .
    OUTPUT:
    
1 . Similar radiographic appearance of pulmonary fibrosis and large left infrahilar lung mass , the latter consistent with history of lung cancer . No definite superimposed infectious pneumonia , but CT may be helpful for more complete assessment in this patient with extensive baseline abnormalities . 2 . Mediastinal and hilar lymphadenopathy , which have been more fully evaluated by CT and PET CT .
