Pseudomembranous Tracheobronchitis: Case Report of a Rare Manifestation of Airway Invasive Aspergillosis.

tracheobronchitis, an uncommon form of invasive pulmonary aspergillosis, is characterized by the development of a pseudomembrane, ulcers, or an obstruction that is predominantly confined to the tracheobronchial tree. Pseudomembranous tracheobronchitis is the most severe form of tracheobronchitis, and only a few cases have been reported in Korea. We report the characteristic chest CT findings in a patient diagnosed with pseudomembranous tracheobronchitis after bronchoscopy and successfully treated by proper antifungal treatment.
