Fig 1 (A) Left (inspiration). Sagittal neck computed tomography revealed that the trachea was held between the innominate artery (star) and a kyphotic cervical spine (thick arrow) front and rear. Right (expiration). The tracheal lumen further collapsed at forced expiration. (B) Axial chest computed tomography (CT) showed that the innominate artery (star) was located more to the left and directly compressed the trachea, creating a crescent shape, along with invagination of the membranous posterior wall during expiration (thin arrow).
