Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The costophrenic angles on the frontal view are obscured , presumably from overlying soft tissue and possibly other external artifact . Given this , the lungs appear hyperinflated . No definite focal consolidation is seen . The cardiac and mediastinal silhouettes are stable . Prominence of the right paratracheal stripe is again seen , which on the prior study was noted to be compatible with tortuosity of vessels seen on CT . Right pleural scarring / thickening is again seen . No overt pulmonary edema is seen . The bones are diffusely osteopenic .
    OUTPUT:
    
Costophrenic angles obscured on the frontal view , presumably due to overlying soft tissue and possibly other external artifact . Given this , the lungs remain hyperinflated without definite acute cardiopulmonary process .
