Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a diffuse opacity in the right lower lobe obscuring the right hemidiaphragm with reticulation . Additionally , there is an opacity in the left base , which is poorly characterized . This may be due to a superimposed pneumonia upon chronic lung fibrosis . Finally , there is a somewhat round asymmetric right apical opacity , which could be pleural thickening and scarring , though a mass or a cavity lesion is somewhat difficult to exclude . There is no pulmonary edema . There is no definite pleural effusion , though small ones would be difficult to visualize on this limited AP exam . There is no evidence of pneumothorax . Multiple calcified upper lobe nodules are likely from prior granulomatous disease . The mediastinal contours are normal . The heart is moderately enlarged . A pacemaker / ICD overlies the mid left chest with the leads in satisfactory position .
    OUTPUT:
    
1 . Bibasilar opacities could reflect aspiration or pneumonia , with apparent underlying chronic interstitial fibrosi . 2 . Right apical opacity , which may be asymmetric apical pleural scarring , though a mass or cavity lesion is difficult to exclude . Recommend further evaluation with a CT of the chest to differentiate scarring from active infection or malignancy . 3 . Moderate cardiomegaly . Results were discussed with Dr . ___ ___ resident ) at 7 :30 AM on ___ via telephone by Dr . ___ at the time the findings were discovered .
