Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size is markedly enlarged . The aorta is tortuous . Enlargement of the hila bilaterally could suggest underlying lymphadenopathy . There is mild pulmonary vascular congestion without overt pulmonary edema . There appear to be small bilateral pleural effusions with bibasilar patchy opacities , potentially atelectasis . No pneumothorax is seen . No acute osseous abnormalities demonstrated .
    OUTPUT:
    
1 . Patchy bibasilar airspace opacities , potentially atelectasis , but infection or aspiration can not be excluded . 2 . Small bilateral pleural effusions . 3 . Mild pulmonary vascular congestion . 4 . Enlargement of the hila bilaterally , potentially suggestive of underlying lymphadenopathy . Comparison with previous radiographs or cross-sectional imaging is recommended , otherwise , further assessment with CT is recommended .
