    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar study ___ ___ . The heart is mildly enlarged with a relative prominence of the left ventricular contour to the left and posteriorly , but no significant enlargement of the left atrium can be identified . The thoracic aorta is moderately widened and elongated with calcium deposits in the wall , mostly at the level of the arch . No local contour abnormality can be identified . The pulmonary vasculature is not congested , and there are no signs of acute parenchymal infiltrates . Comparison with the next previous study demonstrates unchanged appearance of the previously described left basal pleural and parenchymal densities , most likely representing scar formations as they are completely unchanged , and no new infiltrates can be identified . Previously noted patchy infiltrates on the right lung base occupying the posterior segment have now resolved . Thus , at the present time , there is no evidence of any acute infiltrate or significant congestion . Diffuse demineralization of the skeletal structures , as before , accentuated kyphotic curvature in the thoracic spine but no evidence of new vertebral body compression .
    OUTPUT:
    
Stable chest findings in elderly female patient , no evidence of new acute parenchymal infiltrates and no signs of advanced CHF .
