Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . The heart size is within normal limits . No typical configurational abnormality is identified . Moderate widening and elongation of the thoracic aorta is noted , however , no local contour abnormalities or wall calcifications are identified . A retrocardiac rounded structure in the lower mediastinum most likely represents hiatal hernia . The pulmonary vasculature is not congested . No evidence of acute parenchymal infiltrates of pneumonic character can be identified . There exists , however , a general attenuation of the pulmonary peripheral vasculature in combination with a translucent appearance of the lungs , preferentially on the basis where the diaphragms are relatively low positioned and somewhat flattened . All these described findings raise the possibility of COPD . Again , there is no evidence of any acute parenchymal infiltrates , particularly in the left upper lobe area as suspected on the requisition . The lateral view discloses generally demineralized vertebral bodies in the thoracic spine but no conclusive evidence for any vertebral body compression fracture . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
No evidence of acute pneumonia , but findings suggestive of COPD and moderately sized hiatal hernia .
