Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is increased volume loss in the right upper lung with a similar right lateral pleural thickening . The overall appearance suggests a loculated pleural effusion in the right hemithorax . Likewise , there is a persistent lenticular collection along the left upper hemithorax as well as thickening along fissures . This is again most likely to represent a loculated pleural effusion . Compared to the prior study , more dense opacification is suspected in the left lower lobe within the retrocardiac region that may reflect a superimposed process , although , aside from the fact that it is new since ___ , acuity is uncertain . Considerable background opacification appears fairly chronic within both lungs bilaterally . There are also increasing , but small free - flowing components of pleural effusion suspected bilaterally based on the lateral view . The patient is status post sternotomy and coronary artery bypass graft surgery . A pacemaker / ICD device with two leads appears unchanged with leads again terminating in the right atrium and ventricle . The bones appear demineralized with multiple similar compression deformities and bony demineralization .
    OUTPUT:
    
Persistent opacities largely reflecting , most likely loculated pleural effusions . Background reticulation at the lung base is suspicious for pulmonary fibrosis . Focal increased opacification is noted in the left lower lobe , possibly pneumonia in the appropriate clinical setting , although other etiologies including worsening interstitial lung disease could be considered .
