Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest . There are densely calcified bilateral pleural plaques . This limits detailed evaluation of the underlying lung parenchyma . Increased opacity at the left lung base is compatible with pleural effusion , not definitely changed since the recent CT scan given differences in technique . Increased opacity projecting over the right lung base is likely due to superimposed calcified plaque noting the underlying parenchymal opacity would be difficult to exclude . The cardiomediastinal silhouette is stable . No acute osseous abnormalities detected .
    OUTPUT:
    
Densely calcified bilateral pleural plaques which obscure detailed evaluation of the underlying lung parenchyma . Persistent left - sided pleural effusion , not definitely changed in size compared to the recent CT scan . Please note that underlying parenchymal opacity would be difficult to exclude given extensive pleural plaque .
