Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are well inflated . No CHF , focal infiltrate , effusion , or pneumothorax is detected . Right paratracheal soft tissues could represent vascular structures in someone of this age . Slight leftward displacement of the trachea is noted . While this could be positional , it raises the possibility of displacement by the thyroid . The heart is at the upper limits of normal in size . The aorta is unfolded . The right hemidiaphragm is slightly elevated . No free air is seen beneath the diaphragm . Mild to moderate multilevel degenerative changes are noted in the thoracic spine .
    OUTPUT:
    
1 . No acute pulmonary process detected . 2 . Possible leftward displacement of the trachea . If real , this raises the question of displacement by an enlarged right thyroid . Prominent right paratracheal soft tissues may be related to this or could be related to ectatic vessels in someone of this age .
