Mounier-Kuhn syndrome : more than just a cough

Abstract

A 35-year-old man presented with a chronic productive cough and a history of recurrent lower respiratory tract infections. Physical examination was unremarkable as were routine blood investigations. A chest radiograph demonstrated dilation of the trachea and main bronchi. Multiple perihilar cysts with air-fluid levels were seen. Contrast-enhanced chest CT confirmed tracheal dilation with multiple tracheal diverticulae present in the posterior aspect of the proximal trachea. Both main bronchi were also dilated. Bilateral, cystic spaces with air-fluid levels, in keeping with cystic bronchiectasis were seen to involve both lower lung zones, sparing the lung apices.
