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 at the upper limit of normal variation . The configuration suggests a prominence of the left ventricular contour , a finding which in conjunction with the moderately widened and elongated thoracic aorta suggests the possibility of systemic hypertension . There is , however , no evidence of pulmonary vascular congestion . There is a moderate widening of the superior mediastinum in the presence of a non-obstructed and non-deviating trachea . It raises the possibility of some thyroid enlargement or perhaps vascular prominence . Otherwise , the parenchymal areas of the lung are free from any inflammatory abnormalities . The lung bases appear slightly hyperlucent and the low - positioned diaphragms are somewhat flattened . Lateral and posterior pleural sinuses are free . The thoracic spine demonstrates moderate degree of degenerative changes in the form of osteophytic , sometimes bridging reactions mostly in the mid portion of the thoracic spine . No vertebral body depression fracture is identified . Our records do not include a preceding chest examination available for comparison .
    OUTPUT:
    
Cardiac findings suggestive of systemic hypertension but no evidence of significant pulmonary vascular congestion . General appearance of some emphysema and moderate widening of superior mediastinum suggestive of intrathoracic thyroid .
