Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest . As on prior , there is increased interstitial markings throughout the lungs potentially chronic heart failure . Increased soft tissue density seen at the right lung apex medially . This area was not well evaluated on the most recent prior . There has been interval development of an apparent right air-fluid level on the frontal . There is also a moderate left pleural effusion . Cardiac silhouette is enlarged but unchanged . Diffuse osteopenia is noted . No displaced fractures seen .
    OUTPUT:
    
1 . Air-fluid level in the right hemithorax raising concern for hydropneumothorax . Additional imaging with CT is suggested . 2 . Increased density at the right lung apex medially , potentially within the lung apex versus tortuosity of vessels and possible thyroid enlargement . This can be further assessed at time of CT .
