Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Increased interstitial markings are seen throughout the lungs . There is slightly more confluent opacity on the frontal view of the right upper lung laterally . Blunting of the posterior costophrenic angles also suggests small effusions . Cardiomediastinal silhouette is within normal limits . Tortuosity of the descending thoracic aorta is noted . Hiatal hernia on the current exam is suspected . No acute osseous abnormalities , chronic left sided rib fractures are noted . Right shoulder arthroplasty and chronic left shoulder degenerative changes are noted .
    OUTPUT:
    
Increased interstitial markings , thought to be due to interstitial edema . More confluent opacity in the right lung laterally could be more conspicuous underlying parenchymal disease although superimposed infection would be difficult to exclude . Small bilateral pleural effusions .
