Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size remains moderately enlarged . The aorta is tortuous and diffusely calcified . Noted on the prior chest CT , there is a left perihilar opacity and enlargement of the left hilar region with prominence of the mediastinal contours , compatible with known lymphadenopathy and nodularity along the left mediastinal border . There are increased interstitial opacities most pronounced within the lung bases compatible with an underlying chronic interstitial lung disease . Lung volumes are reduced . No new focal consolidation is present . There is no pleural effusion or pneumothorax . Multiple old left - sided rib fractures are present . There is diffuse demineralization of the osseous structures .
    OUTPUT:
    
No significant interval change from the prior study with continued mediastinal and hilar lymphadenopathy . Left perihilar opacity correlates with ill - defined nodularity of the mediastinal pleura , better demonstrated on the prior chest CT . Chronic interstitial lung disease .
