Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are hyperinflated . Heart size is mildly enlarged . The aorta is diffusely calcified . Hilar and mediastinal contours are unremarkable . Pulmonary vasculature is not engorged . Blunting of the left costophrenic angle likely suggest the presence of a small pleural effusion . Patchy left basilar opacity could reflect atelectasis , but infection is not excluded . Scarring within the lung apices is symmetric . Mild diffuse interstitial opacities likely reflect chronic interstitial abnormality . There is diffuse demineralization of the osseous structures with loss of height of several thoracic vertebral bodies , of indeterminate age .
    OUTPUT:
    
Probable small left pleural effusion and patchy left basilar opacity , potentially atelectasis . Loss of height of several thoracic vertebral bodies of indeterminate age .
