Abstract
Tracheobronchomegaly (TBM) or Mounier-Kuhn syndrome, is characterized by marked dilation of the trachea and proximal bronchi associated with recurrent respiratory infections. Clinical signs are not very specific. Diagnosis is mainly based on chest radiography and computed tomography, relying on measurement of the diameter or surface area of the trachea and main bronchi. Treatment is essentially symptomatic, including respiratory physiotherapy and antibiotic therapy. Surgical interventions may sometimes be required. We report the case of a 67-year-old chronic smoker in whom this syndrome was diagnosed in our Pulmonology Department at Mohammed VI University Hospital in Marrakech.
