Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes are present . The cardiac silhouette size appears moderately enlarged . The aorta is slightly tortuous . Crowding of bronchovascular structures is present with more pronounced right perihilar haziness and vascular indistinctness suggestive of mild asymmetric pulmonary edema . Additionally , more focal opacity within the right lung base could reflect atelectasis but infection is not excluded . There appears to be a small left pleural effusion . No pneumothorax is present , however the medial aspects of the lung apices are somewhat obscured by overlying soft tissue structures . No acute osseous abnormalities present .
    OUTPUT:
    
Mild asymmetric pulmonary edema , more pronounced on the right , with small left pleural effusion . More focal patchy right basilar opacity could reflect atelectasis or pneumonia .
