Mounier-Kuhn syndrome (MKS) also known as tracheobronchomegaly is an uncommon condition characterized by dilatation of the trachea and major bronchi.
Bronchial and tracheal diverticula can also accompany tracheobronchomegaly. Sarcoidosis, usual interstitial pneumonia, and cystic fibrosis can cause severe fibrosis of the upper lobes, which may result in tracheal enlargement if there is sufficient tracheal traction.
