Summarize the radiology report findings into an impression within 3 sentences.
    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 of ___ . The heart size remains unchanged and is within normal limits . No configurational abnormality is seen . Mild widening and elongation of the thoracic aorta is noted , but no local contour abnormalities or wall calcifications are identified . The pulmonary vasculature is not congested . No signs of acute or chronic parenchymal infiltrates are present , and the lateral and posterior pleural sinuses are free . No pneumothorax in the apical area . The lateral view discloses a mildly accentuated kyphotic curvature in the thoracic spine , not excessive for patient 's age and there is no evidence of vertebral body compression fractures . In comparison with the next preceding chest examination of ___ , the at that time described mild blunting of the lateral pleural sinuses is not present anymore . An interesting observation is that on both lateral views , there was never any fluid accumulation in the posterior dependent pleural sinuses , thus free pleural effusion can not be identified .
    OUTPUT:
    
Mild widening and elongation of thoracic aorta possibly related to systemic hypertension but no evidence of CHF , pulmonary congestion , acute infiltrates or pleural effusion .
