Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment is limited by patient rotation . A moderate to large right pleural effusion is demonstrated with right basilar opacification , possibly reflective of compressive atelectasis though pneumonia is difficult to exclude . Heart size can not be determined due to the presence of the moderate to large right pleural effusion . The aorta appears diffusely calcified . Hazy perihilar opacification bilaterally is more pronounced on the right and may reflect asymmetric pulmonary edema . Mild widening of the superior mediastinal contour appears relatively unchanged may reflect underlying lymphadenopathy , as demonstrated on the previous CT . No left - sided pleural effusion or pneumothorax is clearly seen . There is evidence of prior vertebroplasty of a vertebral body at the thoracolumbar junction .
    OUTPUT:
    
1 . Moderate to large right pleural effusion with right basilar opacification , likely compressive atelectasis though infection is difficult to exclude . 2 . Bilateral perihilar hazy opacities , more pronounced on the right , potentially reflective of asymmetric pulmonary edema .
