    INPUT: Lung volumes are low . The heart size is normal . The mediastinal and hilar contours are unremarkable .

Pulmonary vascularity is within normal limits . Postsurgical changes are noted in the right chest with partial resection of the right 6th rib , lateral right pleural thickening and chronic blunting of the costophrenic sulcus .
