2. Figure 1
Dynamic airway CT scan without IV contrast during inspiration (A - C) and expiration (D and E) at the level of the aortic arch, including mediastinal window (A), lung window (B and D), and virtual bronchoscopy images (C and E). A 1.7 × 1.0 cm polypoid lesion is seen in the dependent portion of the trachea. Dynamic expiratory sequences indicate slight mobility of the lesion and airway collapsibility. The lesion has predominantly soft-tissue attenuation with small foci of low attenuation.
