The thoracic aorta is moderately widened and elongated , and calcium deposits are seen in the wall mostly at the level of the arch . No local contour abnormality is present . The pulmonary vasculature is not congested . The appearance of the vasculature with irregular distribution in the periphery and areas of increased translucency is compatible with chronic COPD .
