  		Fig. 1B. —50-year-old man with tracheobronchomalacia and air trapping. Dynamic expiratory CT scan obtained at level similar to A shows excessive collapse of trachea (black arrows), consistent with malacia. Also note areas of geographically marginated radiolucency (white arrows) within lungs, consistent with air trapping.

  		Fig. 1D. —50-year-old man with tracheobronchomalacia and air trapping. Dynamic expiratory CT scan obtained at level similar to C shows excessive narrowing of bronchi (black arrows) consistent with bronchomalacia. Also note extensive areas of geographically marginated radiolucency (white arrows) within lungs, consistent with air trapping.
