Een vrouw met in- en expiratoir piepende ademhaling

A 42-year-old woman was seen with an inspiratory stridor and expiratory wheezing. The wheezing responded quickly to asthma treatment. The stridor, however, was caused by a significant narrowing of the trachea between the branching of a tracheal bronchus (‘bronchus suis’ or ‘ pig bronchus’) and the main carina.
