Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size remains moderately enlarged . The aorta is diffusely and densely calcified . Interstitial opacities are more pronounced in the right lung compared to the left , and again may reflect asymmetric pulmonary edema , but lymphangitic carcinomatosis is not excluded . Mediastinal and hilar contours are otherwise unchanged . Marked emphysematous changes are again noted . Right lower lobe lung mass is not substantially changed in the interval . Previously demonstrated pulmonary and pleural metastases are better assessed on the previous CT . Small left pleural effusion is again noted . There is no pneumothorax . Remote bilateral rib fractures are again seen . Mild compression deformity of a mid thoracic vertebral body remains unchanged . Clips are noted in the right upper quadrant of the abdomen .
    OUTPUT:
    
1 . Unchanged right lower lobe lung mass . Known pulmonary and pleural metastases are better demonstrated on the prior CT . 2 . Small left pleural effusion . 3 . Interstitial opacities are more pronounced on the right , possibly reflective of asymmetric pulmonary edema but lymphangitic carcinomatosis is not excluded .
