    INPUT: Frontal and lateral views of the chest demonstrate mildly prominent cardiac silhouette . Atherosclerotic arch calcifications are noted . The mediastinal and hilar contours are within normal limits . The left lung is clear of confluent consolidation or pleural effusion . A tiny focus of opacity in the lateral left upper lobe corresponds with a focus of linear opacity on CT dated ___ , suggestive of chronic infection / inflammation . In the right lung , streaky right upper lobe opacities persist , which also likely reflect chronic change . There is trace if any small right pleural effusion , with a persistent rounded right costophrenic contour , previously confirmed to be rounded atelectasis on CT . Surgical ___ are seen in the subdiaphragmatic location . Multilevel lower thoracic wedge compression deformities are unchanged as compared to prior CT from ___ . There is no evidence of pneumothorax or pulmonary edema .
    OUTPUT:
    
1 . Persistent right greater than left upper lobe linear opacities likely reflect chronic post infectious or inflammatory changes . 2 . Persistent rounded atelectasis in the right costophrenic angle .
