Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are reduced . There are diffuse interstitial opacities , most pronounced within the lung bases and more so in the left lung base compared to the right . Additionally , bronchiectatic changes are also most pronounced within the lung bases , with bronchial wall thickening . Increased opacification within the left lung base compared to the prior radiograph may suggest the presence of a superimposed infection or atelectasis . Assessment of the lateral view is limited due to the patient 's inability to raise her left arm , and a left humeral prosthesis is imaged . No definite pleural effusion is seen . There is mild pulmonary vascular congestion . The hilar contours appear relatively unchanged , with mild - to - moderate cardiomegaly and tortuosity of the thoracic aorta again noted . No pneumothorax is present . Bilateral old rib deformities are present . Compression deformities of several mid thoracic vertebral bodies are present and unchanged compared to the prior CT . Mild compression deformity of an upper lumbar vertebral body is also stable .
    OUTPUT:
    
1 . Mild pulmonary edema . 2 . Chronic interstitial lung disease , with slightly increased opacity in the left lung base , which could represent superimposed infection or atelectasis .
