Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest . Coarse interstitial markings are again noted suggestive chronic underlying lung disease . Persistent opacity projects in the posterior segment of the right upper lobe potentially due to scarring . Increased opacity at the right lung base and left lung laterally is again compatible with pleural plaques . There is no evidence of effusion . There is no new consolidation . Cardiomediastinal silhouette is unchanged . No displaced fracture is identified .
    OUTPUT:
    
No definite acute cardiopulmonary process . If high clinical concern for fracture , dedicated rib series could be performed .
