Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size remains mildly enlarged with a left ventricular predominance . Diffuse calcification of the thoracic aorta is noted . The mediastinal and hilar contours are unchanged . Fiducial seeds are seen within a right lower lobe lesion as well as within the left lower lobe lesion with surrounding ill - defined opacity , as demonstrated on prior CT . Right apical lung nodules redemonstrated , but better demonstrated on a recent CT . The pulmonary vascularity is not engorged . No pleural effusion or pneumothorax is identified . Known lytic lesion involving the distal left clavicle is not well visualized on current exam .
    OUTPUT:
    
Ill - defined opacities in both lower lobes at the site of prior radiation therapy treatment , which could reflect radiation pneumonitis , though infection is not excluded . Findings appear similar compared to recent CT . Right apical nodule is redemonstrated , again better demonstrated on recent CT .
