Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are normally expanded . Hazy opacification throughout the lungs and some interstitial / Kerley B lines , particularly at the periphery of the left lung suggest pulmonary edema . The heart is top normal , although exaggerated by AP technique . The mediastinal and hilar contours are partially obscured , but thickening of the right paratracheal stripe is due to venous engorgement or adenopathy . There is no large pleural effusion or pneumothorax .
    OUTPUT:
    
Mild pulmonary edema and top normal size of the heart . Suggest repeat chest radiographs after treatment of possible edema to unmask interstitial pneumonia or non cardiac edema masquerading as heart failure .
