Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable including marked tortuosity of the thoracic aorta . The heart is probably borderline in size . Similar to prior findings there is a small pleural effusion on the right , no definite one on the left . Mild pleural thickening with a smoothly lobular appearance and streaky opacities at the right lung base suggest minor scarring and probably some degree of round atelectasis associated with persistence of the effusion . Chest is hyperinflated . Severe kyphoscoliosis is again noted . Bones appear demineralized . A healed left clavicle fracture appears unchanged .
    OUTPUT:
    
Persistent small pleural effusion with opacity suggesting associated atelectatic change . Superinfection is doubted but difficult to entirely exclude . Opacity at the right lung base appears mildly nodular , probably due to round atelectasis , but it may be appropriate to consider follow - up radiographs in ___ months versus consideration of chest CT since this appears new .
