Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well inflated with no obvious consolidation ; however , there is a suggestion of peribronchial opacification in the retrocardiac left lower lobe . Left anterior oblique chest radiograph is recommended to better image this area . A small round opacity in the right mid field is a vessel on end or calcified granuloma . The lungs are otherwise clear and there is no pleural abnormality . The cardiomediastinal and hilar silhouettes are normal .
    OUTPUT:
    
Possible retrocardiac lung lesion would be better evaluated on a left anterior oblique chest radiograph . Otherwise normal study .
