    INPUT: Frontal and lateral chest radiograph demonstrates mildly enlarged cardiac silhouette which is partially obscured by an a dense left lower lobe opacification likely representing a combination of moderate pleural effusion and atelectasis . However , underlying infectious process is not excluded . Mediastinal and hilar contours are unremarkable . Evidence of remote healed anterior right 3rd rib fracture identified . Rounded ossific density projecting adjacent to the right coracoid process may represent a loose body within the joint space . Significant degenerative change identified in the bilateral glenohumeral joints . Compared to ___ , there has been interval progression of multiple thoracic and lumbar compression deformities including now almost complete loss of anterior vertebral body height of a mid thoracic vertebrae .
    OUTPUT:
    
Left lower lobe opacification likely combination of atelectasis and moderate pleural effusion . Underlying infectious process not excluded . Mild cardiomegaly , incompletely assessed by left lower lobe opacification . Interval progression of multiple thoracic and lumbar vertebral compression deformities .
