Dilated aorta with unfolding of arch. Ascending aorta is forming the upper part of the right cardiac border and descending aorta the upper part of left cardiac border. The left pulmonary artery is seen as a double density within the descending aortic shadow on the left side. The superior vena caval shadow is seen in the region of the medial end of right clavicle, mainly because the film is rotated towards right as evidenced by the higher distance between the medial end of right clavicle and the spine.
