Tracheobronchomegaly-Mounier-Kuhn syndrome.

Tracheobronchomegaly is a rare disorder of uncertain etiology, characterized by marked dilatation of the trachea and major bronchi, associated with tracheal diverticulosis, bronchiectasis and recurrent respiratory tract infection. We are reporting a 60-year-old man from the Kingdom of Saudi Arabia with this condition and review the literature for such a rare entity.
