Mounier Kuhn Syndrome: A Rare Variety of Bronchial Dilatation

Back ground: Mounier Kuhn’s syndrome is a rare condition. It is characterised by an increase in the diameter of the trachea and main bronchi. Imaging plays a fundamental role in confirming the diagnosis. This syndrome is little known and has not benefit of enough studies allowing a better comprehension of its pathophysiology and a performing therapeutic approach.

Case presentation: In this paper, we report the case of a 53-year-old man suffering from recurrent respiratory infections. Imaging has made the diagnosis of Mounier Kuhn syndrome by showing an increase in the diameter of the trachea and main bronchi. The treatment was based on physiotherapy and appropriate antibiotic therapy in case of infectious outbreak.

Conclusions: This long-neglected “orphan disease” should receive more research attention in order to provide better understanding of its aetiology, pathogenesis and multimodality treatment.
