Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are diffuse reticular opacities with blunting of the bilateral costophrenic angles on the lateral view . Findings are similar compared to chest radiograph from a few days prior and similar to multiple prior examinations . Mild cardiomegaly overall appears unchanged . Though this has previously been described as pulmonary edema , the stability over several radiographs , suggests this could be secondary to chronic interstitial lung disease . No definite superimposed confluent consolidation is identified . There is no pneumothorax . Cardiomediastinal and hilar contours are unchanged from prior examination .
    OUTPUT:
    
Diffuse reticular opacities with blunting of the bilateral costophrenic angles , similar to multiple prior examinations . Though this could reflect pulmonary edema in the appropriate clinical setting , findings may reflect underlying chronic interstitial lung disease .
