Tracheobronchomegaly with Bronchomalacia / 대한내과학회지

ABSTRACT

Tracheobronchomegaly, or Mounier-Kuhn syndrome, is a rare clinical and radiologic condition characterized by marked tracheobronchial dilatation and recurrent lower respiratory tract infections. It is thought to be due to a congenital anomaly. A diagnosis is typically made using computed tomography (CT) and bronchoscopy. Symptoms can range from minimal with preserved lung function to severe respiratory failure. Here, we present the case of a 50-year-old male who was referred to our hospital for chronic cough, sputum, and dyspnea. In addition, the patient showed tracheobronchomegaly with bronchomalacia on CT and bronchoscopy. This report describes a rare case of Mounier-Kuhn syndrome with a literature review.
