Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is blunting of the right costophrenic angle and minimal opacity at the right lung base , which may reflect pleural parenchymal thickening / scarring given the recent intervention . However , pneumonia is also possibility in the appropriate clinical setting . Minimal amount of fluid is seen layering within the minor fissure . The right upper lung is clear . The left lung is entirely clear . There is no pulmonary edema . Cardiomediastinal and hilar contours are within normal limits . Elevation of the right hemidiaphragm is noted . Multiple right sided rib fractures are re-demonstrated . No pneumothorax . Resolution of previously noted pneumomediastinum and subcutaneous emphysema .
    OUTPUT:
    
Right lower lobe opacity . Findings may reflect pleural parenchymal scarring given recent pneumothorax and intervention at that site . However , an acute pneumonia would be difficult to exclude in the appropriate clinical setting . Small right pleural effusion .
