    INPUT: There are extensive diffuse patchy multifocal airspace opacities throughout both lungs . Although they appear more pronounced compare with the prior film , this is likely accentuated due to technical differences . Given th the presence of diffuse opacities , it is difficult to exclude superimposed CHF , but the left lung base laterally is relatively clear and no pleural effusion is seen on either side , making superimposed CHF less likely . Again seen are calcified mediastinal and left hilar nodes and a calcified granuloma in the left upper zone , consistent with prior granulomatous disease . Cardiomediastinal silhouette is prominent , but unchanged allowing for technique . Left - sided pacemaker with leads over right atrium and right ventricle unchanged .
    OUTPUT:
    
1 . Multifocal bibasilar opacities seen throughout both lungs , consistent with airspace disease . In the appropriate clinical setting , this would be compatible with pneumonia or ARDS . Doubt superimpose CHF . Please see comment above . 2 . Calcified nodes and granuloma consistent with prior granulomatous disease .
