Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a left chest pacer device with associated dual leads projecting in unchanged configuration . There are low lung volumes , likely accentuating cardiac size . Within this limitation , the cardiac and mediastinal silhouette is unchanged from prior chest x-ray from ___ . There is probably mild cardiomegaly . Calcified pleural plaques most conspicuous at the right lung base , unchanged from prior exam . There is diffuse , hazy right lung airspace opacity , all involving the right lower lobe most conspicuously . Additional airspace opacities involving the left lung base obscure the left hemidiaphragm . There is no overt pulmonary edema . There is no pneumothorax . There are small bilateral pleural effusions .
    OUTPUT:
    
1 . Right more than left lower lobe airspace opacities are new from prior exam , and while this appearance may represent asymmetric pulmonary edema , particularly in the setting of trace bilateral pleural effusions and mild cardiomegaly , this appearance could also represent multifocal infection . Correlate with signs / symptoms and lab findings suggestive of infection . 2 . Calcified pleural plaques are unchanged .
