Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . There are relatively low lung volumes . There is diffuse increase in interstitial markings bilaterally , similar as compared to the prior study which may be due to pulmonary edema superimposed upon emphysema . More confluent opacity projecting over the right mid - to - lower lung is seen which could relate to fluid overload ; however , an underlying consolidation due to infection is not excluded . No large pleural effusion is seen , although some trace pleural effusions are difficult to exclude . The cardiac silhouette remains enlarged . The mediastinal contours are stable . No pneumothorax is seen .
    OUTPUT:
    
Diffuse increase in interstitial markings bilaterally raises concern for pulmonary edema superimposed on emphysema . More confluent opacity in the right mid-to - lower lung , underlying consolidation due to infection is not excluded . It is difficult to exclude trace pleural effusions . Consider repeat after diuresis for further evaluation .
