Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest were obtained . There is no definite sign of pneumonia or CHF . Along the left heart border is subtle density which is most compatible with slightly prominent bronchovasculature , though the possibility of a very early or partially resolving pneumonia is impossible to exclude . Cardiomediastinal silhouette is normal . Bony structures are intact . No free air below the right hemidiaphragm .
    OUTPUT:
    
No definite signs of pneumonia , though very subtle opacity in the left lower lung could represent a minimal consolidation in the correct clinical setting .
