Computed tomography of diffuse tracheal stenosis in Wegener granulomatosis.

A patient with Wegener granulomatosis presented with diffuse tracheal narrowing and was evaluated using CT and cine-CT. The CT findings included severe laryngeal and tracheal airway narrowing, due to abnormal soft tissue within the laryngeal cartilages and tracheal rings, and enlarged abnormally calcified tracheal cartilages. Computed tomography precisely confirmed the site, level, and submucosal extent of tracheal narrowing, not obtainable on physical or bronchoscopic examination, and assisted in choosing a site for tracheostomy. Wegener granulomatosis should be considered in patients with diffuse tracheal narrowing even when the typical histology is not present.
