Clinical coagulation of tracheal tumors was hospitalized. X-ray examination: Chest radiograph, no substantial lesions in both lungs. The tracheal anteroposterior slice corresponds to a 2.5×2.5 cm high-density shadow of the sternoclavicular joint, and the border is still clear. The translucent bands were visible on both sides of the uniform density block and no abnormalities were found on both sides of the tracheal wall. Left and right bronchial openings were unobstructed, and no lymphadenopathy was seen under the protuberances. Lateral tracheal tomography, equivalent to the aortic arch upper edge visible 2.5 × 3cm size density increased shadow. Block shadow
