Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Diffuse coarse interstitial opacities bilaterally with superior hilar retraction and upper lobe architectural distortion appear similar , compatible with known sarcoidosis . The cardiac and mediastinal contours appear unchanged . Multiple calcified mediastinal and hilar lymph nodes are re- demonstrated . Bilateral hilar enlargement suggests underlying pulmonary arterial hypertension . No overt pulmonary edema is present . No new gross focal consolidation , pleural effusion or pneumothorax is seen . Multiple chronic bilateral rib deformities are re- demonstrated . Additionally , mild height loss of a vertebral body at the thoracolumbar junction is unchanged . Bilateral breast implants are again noted .
    OUTPUT:
    
No gross interval change in fibrosing chronic interstitial lung disease likely due to sarcoidosis . Bilateral hilar enlargement suggestive of pulmonary arterial hypertension .
