Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest were provided . Lung volumes are low , and allowing for this , subtle increase in the bronchovascular markings likely reflects some degree of crowding of bronchovasculature , though mild pulmonary edema would be difficult to exclude in the correct clinical setting . There is no overt sign of pneumonia . There is no effusion or pneumothorax . The cardiomediastinal silhouette is stable . Bony structures are intact .
    OUTPUT:
    
Possible mild interstitial edema . Limited exam due to low lung volumes . Otherwise grossly unremarkable .
