Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Small bilateral pleural effusions , left greater than right , are not significantly changed compared to prior chest radiograph from ___ . Bibasilar consolidative opacities are likely at least partially compressive atelectasis , although infection at either lung base is certainly possible . Linear opacities in the right mid to upper lung in the region of suture chain are unchanged , consistent with scarring . Nodular right mid lung opacities are not appreciably changed . Mild enlargement of the cardiac silhouette is not significantly changed . Multiple calcified hilar and mediastinal lymph nodes are again noted , in keeping with known sarcoidosis .
    OUTPUT:
    
No significant interval change with persistent small bilateral pleural effusions , left greater than right , and bibasilar consolidative opacities that are at least partially attributable to atelectasis , although infection in either base is not excluded . Patchy right mid lung opacities could be atelectasis versus infectious foci , not significantly changed .
