Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable including fullness of the upper mediastinal contour to the left of midline , reflecting a combined shadow of the aorta and main pulmonary artery , which is probably borderline enlarged . This area did not show involvement for malignancy on the prior PET - CT but the trachea does appear splayed somewhat more towards the right with a more horizontal configuration to the left main stem bronchus . Possibly , this could indicate developing mediastinal lymphadenopathy . An irregular mass at the left lung apex appears unchanged allowing for differences in technique . Streaky opacities at the left lung base indicates minor atelectasis or scarring . There is no pleural effusion or pneumothorax . There are three new mild compression deformities since remote prior radiographs from ___ , although somewhat difficult to compare to more recent studies such as radiographs from ___ , although the indication is that at least the lower two , which probably relate to the T10 and T11 vertebral bodies , are new since ___ and similar but more likely increased since the more recent PET - CT dated ___ .
    OUTPUT:
    
1 . No evidence of acute cardiopulmonary disease . 2 . Mild change in the configuration of the mediastinum , which raises concern for developing lymphadenopathy . 3 . Several mild compression fractures of the thoracic spine , the lower two of which ( probably involving T10 and T11 ) , likely acute or subacute .
