Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest . The lungs are hyperinflated but clear of focal consolidation or effusion . Slightly increased interstitial markings are seen throughout . The cardiac silhouette is mild - to - moderately enlarged . Atherosclerotic calcification is noted at the aortic arch . There is a severe compression deformity in the lower thoracic spine , age indeterminate .
    OUTPUT:
    
1 . Hyperinflation without focal consolidation . Diffusely increased interstitial markings throughout the lungs could be chronic and due to underlying chronic parenchymal changed although interstitial edema is also possible . 2 . Severe compression deformity in the lower thoracic spine which is age indeterminant given lack of priors to document chronicity and clinical correlation is suggested .
