Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest were reviewed . The cardiomediastinal contours are stable . Prominence of the right hilum is new since the prior study . There are bibasilar opacities with blunting of the costophrenic angles concerning for atelectasis with small effusions . Multiple large pulmonary nodule is again seen , grossly stable since the prior study , but better assessed on the prior CT chest . Again seen is a left retrocardiac opacity , which now appears slightly larger and is obscuring part of the left hemidiaphragm . This likely represents a mass , seen on the prior CT in the same location , with a component of adjacent atelectasis , accounting for the slight increase in size . Single lead pacemaker is again seen with tip terminating in right ventricle . Left humeral prosthesis is incompletely imaged .
    OUTPUT:
    
1 . New bibasilar atelectasis and possible small pleural effusions . 2 . Multiple pulmonary masses again seen , including a mass in the left lower lobe which may have adjacent atelectasis . 3 . Prominence of the right hilum , increased since the prior study .
