    INPUT: The cardiomediastinal and hilar contours are within normal limits . The aorta is tortuous and calcified . Bilateral interstitial opacities are suggestive of an atypical infection or potentially related to fluid overload . A calcified 6 mm nodule projected over the right mid lung is consistent with a granuloma . Multiple compression deformities are seen throughout the thoracic spine of unknown chronicity .
    OUTPUT:
    
Predominantly interstitial lung pattern which raises concern for atypical pneumonia versus fluid overload . Multiple compression deformities of the thoracic spine of unknown chronicity .
