A 46-year-old man with tracheomegaly, tracheal diverticulosis, and bronchiectasis: Mounier-Kuhn syndrome

Abstract

Lower respiratory tract infection is one of the common causes of morbidity in India which is occasionally undiagnosed. In this regard tracheobronchomegaly is one of those conditions which masquerade as chronic bronchitis and bronchiectasis and are usually undiagnosed. It is a well-defined clinical and radiologic entity characterized by marked dilatation of the trachea and the central bronchi and is frequently associated with recurrent lower respiratory tract infection. Tracheobronchomegaly has been described by a variety of names, including Mounier-Kuhn syndrome, tracheal diverticulosis, tracheobronchiectasis, tracheocele, tracheomalacia, and tracheobronchopathia malacia.
