Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The left lung volume is low with elevation of left hemidiaphragm suggesting volume loss likely secondary to left basilar atelectasis . Small moderate left pleural effusion . Right basilar atelectasis . There are extensive indistinct interstitial markings which are more likely consistent with pulmonary edema but some may reflect chronic lung disease and / or interstitial lung disease . The cardiomediastinal silhouette is enlarged with associated pulmonary vascular congestion . Stable calcification of the aortic arch and descending aorta .
    OUTPUT:
    
1 . Interstitial opacities and worsened cardiomegaly likely consistent with mild to moderate pulmonary edema . However , some interstitial disease could possibly be due to chronic lung disease such as ILD . 2 . Small moderate pleural effusion . 3 . Interval worsening of bibasilar atelectasis , left worse than right .
