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.
一名韦格纳肉芽肿患者出现弥漫性气管狭窄，并接受了CT和动态CT评估。CT表现包括严重的喉和气管气道狭窄，这是由于喉软骨和气管环内的异常软组织以及异常钙化的气管软骨增大所致。计算机断层扫描精确地确定了气管狭窄的部位、水平和黏膜下范围，而这些在体格检查或支气管镜检查中无法获得，并且有助于选择气管造口术的部位。即使不存在典型的组织学表现，对于出现弥漫性气管狭窄的患者也应考虑韦格纳肉芽肿。
