Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest radiographs show stable cardiac , mediastinal and hilar contours . Biapical pleural thickening also appears unchanged . A lingular nodule noted on the prior CT is not well visualized on this examination probably due to differences in technique . A newly apparent area of increased density projecting over the right lung apex and course of the right posterior lateral fifth rib suggests an interval rib fracture although it is difficult to exclude a pulmonary nodule . Follow - up by was also previously recommended for a small pulmonary nodule in the lingula . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
1 . No evidence of acute cardiopulmonary disease . 2 . Possible nodule versus bone finding or scarring at the right apex . Previously , one year follow - up was recommended for a lingular nodule , which can not be assessed by radiography . Follow - up chest CT is recommended to assess both findings .
