    INPUT: PA and lateral images of the chest show a pacemaker in place with the wires in proper position in the right atrium and left ventricle . The heart is normal in size . There is mild tortuosity of the aorta . There is mild hyperinflation of the lungs with flattened hemi-diaphragms suggesting underlying chronic lung disease . Prominent coarse interstitial markings could also represent underlying chronic lung disease , elevated pulmonary venous pressures , or both . There is no consolidation , pleural effusion or pneumothorax . The spine is osteoporotic with evidence of a prior kyphoplasty in the mid thoracic spine . There are vertebral compression fractures of unknown chronicity in the two vertebral bodies superior to the prior kyphoplasty .
    OUTPUT:
    
1 . No evidence of pneumonia . 2 . Coarse interstitial markings may represent chronic lung disease , elevated pulmonary pressures , or both . 3 . Multiple vertebral compression fractures in the mid thoracic spine of unknown chronicity .
