Mounier-Kuhn Syndrome- A Rare Case Report

Abstract

Mounier-Kuhn syndrome (M-K Syndrome) also known as Tracheobronchomalacia (TBM) often seen in middle aged and elderly people. Weakness of the tracheal and bronchial walls allows the posterior and anterior walls to draw nearer together during expiration and coughing, producing a varying obstruction. The main complaints are dyspnea, cough, phlegm and haemoptysis. Acquired TBM often presents with recurrent respiratory tract infections and mistreated as chronic bronchitis, pneumonia and the dyspnea, often treated as asthma, with poorer outcomes. Here, a case of 70-year-old male was presented with complaints of cough with expectoration since four months. Bronchoscopy, cineradiography, spirometry and intrabronchial pressure measurements are the diagnostic methods used. TBM is a progressive condition and to be considered in the diagnosis of obstructive pulmonary diseases and in the assessment of the functioning capacity of dyspneic patients. Treatment is conservative and symptomatic; in selected cases surgery may also be beneficial.
