Sixty-four year old patient with bronchogenic carcinoma who presented with dyspnea. (A) Chest roentgenogram reveals a large mediastinal mass that surrounds and narrows the trachea to 5 mm in diameter. (B) A metallic stent (arrows) has been inserted that opens the trachea to 14 mm in diameter. The patient’s dyspnea subsequently resolved.

(A) Prestent computed tomographic scan at the level of the aortic arch showing a large mediastinal mass causing severe compromise of the airway with a high-grade stenosis (5-mm diameter) of the trachea. (B) Post-stent computed tomographic scan showing successful stent placement and patency of the trachea measuring 14 mm in diameter.
