A case report of Mounier-Kuhn syndrome

Mounier-Kuhn syndrome is a congenital abnormality characterized by tracheobronchomegaly as a result of atrophy or absence of elastic fibers and thinning of smooth muscle layer in trachea and main bronchi. The usual presentation is one of recurrent respiratory tract infections with a broad spectrum of functional impairment ranging from minimal disease with preservation of lung function to severe disease in the form of bronchiectasis. We describe a case of an elderly man who presented with a recurrent respiratory infection who was subsequently diagnosed as Mounier-Kuhn syndrome.
