Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are now low in both lungs ; left hemidiaphragm is chronically elevated . Moderate cardiomegaly is exaggerated by low lung volumes also crowding of pulmonary vasculature and simulates mild edema . Mediastinal caliber , particularly in the right lower paratracheal station is increasing . Some of the retrocardiac airspace opacity , seen best on the lateral projection , is atelectasis , but least one lung mass seen on recent abdomen and Chest CT scans , which also showed extensive central adenopathy developing over the past year . There may be new left upper lung nodules as well . Small pleural effusions are present .
    OUTPUT:
    
Borderline interstitial edema . Increasing central adenopathy and possible lung masses . CT scanning recommended for evaluation .
