    INPUT: Cardiac silhouette size appears mildly enlarged but unchanged . The mediastinal and hilar contours are similar . There is mild pulmonary vascular congestion and small bilateral pleural effusions . Patchy opacities in the lung bases may reflect a combination of the patient 's known bronchiectasis and fibrosis with superimposed atelectasis . Elevation of the right hemidiaphragm is unchanged . Known right hilar mass is better assessed on the previous radiograph . Marked degenerative changes are seen involving the left shoulder with narrowing of the left acromiohumeral interval suggestive of underlying rotator cuff disease .
    OUTPUT:
    
1 . Mild pulmonary vascular congestion and small bilateral pleural effusions . 2 . Known right hilar mass is better assessed on the previous CT . 3 . Patchy opacities in the lung bases may reflect a combination of atelectasis as well as known bronchiectasis with fibrotic changes .
