Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral images of the chest . There are low lung volumes . There are increased interstitial lung markings throughout the lungs but more confluent at the bases . In conjunction with prior CT , these finding likely reflect a chronic interstitial process , but the lack of old prior studies for comparison precludeds evaluation for change and a superimposed component of edema or infection would be possible . The posterior costophrenic angles are excluded from this exam , but there is no evidence of large pleural effusion . There is no pneumothorax . The cardiomediastinal silhouette is top - normal is size , accentuated by low lung volumes There are right lateral rib fractures involving right ribs ___ , which more clearly demonstrate callous formation on recent CT . A linear calcific density is noted in the retrosternal region on the lateral , raising the possibility of calcified pleural plaque .
    OUTPUT:
    
1 . Increased interstitial lung markings throughout the lungs more confluent at the bases , likely reflecting at least some component chronic interstitial process . A superimposed component of edema or infection would be possible . 2 . Right lateral rib fractures involving ribs ___ which show some callous formation on recent CT indicated they are not acute .
