Characteristic bronchoscopic manifestations of TO.
(A) Stage I: Scattered plaque-like inflammatory infiltrations of yellow-whitish soft lesions distributed overlying the mucosa of the lumen, accompanied with the change of mucosa hyperemia edema. (B) Stage II: Numerous dispersed or diffuse existence of both sessile spicules and cartilaginous nodules projecting into the lumen with a typical “cobblestone or stalactitic cave” visualization. (C) Stage III: A deformed, rigid and narrow feature of the airway, causing airway narrowness even obstruction.
