    INPUT: Frontal and lateral views of the chest were obtained . There is diffuse increased interstitial markings bilaterally , which may be due to moderate interstitial edema , although chronic underlying interstitial process may alternatively be present . No definite focal consolidation is seen . There is no pleural effusion or pneumothorax . The aorta is calcified and tortuous . The cardiac silhouette is top normal . There is diffuse osteopenia . There is moderate - to - severe compression of two vertebral bodies at the thoracolumbar junction , of indeterminate age , given lack of priors for comparison .
    OUTPUT:
    
1 . Diffuse increased interstitial markings may relate to interstitial edema , although underlying chronic interstitial process may also be present . No pleural effusion or focal consolidation . 2 . Moderate - to - severe compression of two vertebral bodies at the thoracolumbar junction / lower thoracic region , of indeterminate age , given lack of priors for comparison .
