Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart is top normal size . Widening of the mediastinum is consistent with mediastinal and hilar lymphadenopathy as seen on CT scan . Lung volumes are low with atelectasis seen in both bases . There is an opacity projecting over the mid right lung likely corresponding to the site of intervention possibly reflecting hemorrhage in that region . Neighboring hilar region also appears to have increased in size , likely secondary to the same process . Left lung is clear . No significant pleural effusions , and no pneumothorax .
    OUTPUT:
    
1 . Focal opacification of the mid right lung likely represent post - surgical changes and is consistent with hemorrhage and / or atelectasis . 2 . Bibasilar atelectasis .
