    INPUT: Heart size is mildly enlarged , unchanged . Mediastinal and hilar contours are similar . Pulmonary vasculature is not engorged . Pleural calcification is again noted on the lateral view suggestive of prior asbestos exposure . Minimal patchy opacity is seen within the left lung base , as seen previously on the chest radiograph from ___ and the thoracic spine radiograph from ___ , which likely reflects this pleural calcification en face . There is no new focal consolidation or pneumothorax . Blunting of the left costophrenic sulcus suggests the presence of a trace left pleural effusion . Scarring is noted within the lung apices .
    OUTPUT:
    
Pleural calcifications , as noted on the prior thoracic spine radiograph from ___ , suggestive of prior asbestos exposure .
