Demonstration of tracheal bronchus associated with tracheal stenosis using direct coronal computed tomography.

A 2-year-old boy presented with chronic wheezes and was refractory to medical treatment. A high carina with bilateral bronchial stenosis was erroneously diagnosed by bronchoscopic examination. Serial direct coronal computed tomographic scans showed a displaced right upper lobe tracheal bronchus associated with tracheal stenosis below the abnormal bronchus. A direct coronal computed tomographic scan of the tracheobronchial tree is a useful imaging technique for the delineation of airway configuration when the bronchoscope fails to pass beyond a stenotic region. A coronal computed tomographic scan may make invasive tracheobronchography unnecessary.
