Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well expanded . There is a conspicuity of the interstitial markings with reticular opacities more pronouced in the lung bases which is not significantly changed from prior radiographs . No focal parenchymal opacities are present . A prominent epicardial fat pad is noted in the right and is unchanged from prior . The heart is moderately enlarged with significant left atrial contribution , unchanged from prior . Otherwise , the cardiomediastinal and hilar contours are unremarkable . The azygos vein is not prominent and there is no apical vascular redistribution . There is no pleural effusion or pneumothorax . No rib fractures are identified .
    OUTPUT:
    
Although this appearance can be seen with interstitial edema , chronic reticular opacities in the lung bases without other signs of vascular congestion or edema are more suggestive of chronic interstitial lung disease in the setting of stable moderate cardiomegaly .
