Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderate enlargement of the cardiac silhouette is unchanged . The mediastinal contours are stable , with widening of the right paratracheal stripe compatible with underlying mediastinal lymphadenopathy . Diffuse interstitial markings are again seen with ground - glass opacities , perhaps minimally worse in the right lung base compared to the prior study . These findings are compatible with chronic interstitial lung disease with a possible superimposed process . No pleural effusion or pneumothorax is identified . There are no acute osseous abnormalities .
    OUTPUT:
    
Diffuse lung disease , with slight interval worsening of opacification in the right lung base . These findings may reflect superimposed pulmonary edema on a background of chronic lung disease , though these findings could also be related to acute exacerbation of a recurrent pulmonary abnormality .
