Tracheobronchomegaly

Tracheobronchomegaly is a very rare congenital disorder of the lung primarily characterized by an abnormal widening of the upper airways.[2] The abnormally widened trachea and mainstem bronchi are associated with recurrent lower respiratory tract infection and copious purulent sputum production, eventually leading to bronchiectasis and other respiratory complications.[3]

Cause

Diagnosis

Woodring et al. (1991) suggested the following diagnostic criteria for tracheomegaly in adults based on chest radiography:[4]

  • Adult Males: Tracheal transverse diameter > 25 mm and sagittal diameter > 27 mm.
  • Adult Females: Tracheal transverse diameter > 21 mm and sagittal diameter > 23 mm.

Treatment

History

The term "Mounier-Kuhn syndrome" derives from the characterization of the condition by Prof. Pierre-Louis Mounier-Kuhn in 1932, while the name "tracheobronchomegaly" was introduced by Katz et al. in 1962.[5][6][7]
