Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac silhouette size is mild to moderately enlarged . Dense mitral annular calcifications are noted . The aorta is diffusely calcified . Prominence of the hila is compatible with known lymphadenopathy , and known mediastinal lymphadenopathy is not well depicted on this exam . Small bilateral pleural effusions , left greater than right , persist . Opacification of the left lung base may reflect atelectasis though infection is not excluded . Mild right basilar opacity also may reflect atelectasis . No Moderate interstitial pulmonary edema is seen . Right lateral pleural thickening is unchanged . There is no pneumothorax . No acute osseous abnormalities are seen .
    OUTPUT:
    
1 . Moderate interstitial pulmonary edema with small bilateral pleural effusions , left greater than right . 2 . Bibasilar airspace opacities , left more so than right , may reflect atelectasis but infection can not be excluded . 3 . Hilar and mediastinal lymphadenopathy better assessed on prior cross - sectional imaging .
