We are reporting a case of a 35-year-old man with chronic cough, increased sputum production, breathlessness with fever. Computed tomography of chest showed tracheal dilation (diameter, 31 mm) and emphysematous changes. Fiberoptic bronchoscopy revealed enlarged trachea and main bronchi. Pulmonary function testing showed combined ventilatory defect. Histopathological examination of biopsy specimens from the bronchi and the tracheal wall suggestive of Mounier-Kuhn syndrome. The present case is an example for under diagnosis, as he was treated twice with anti-tubercular treatment for radiological shadows. The diagnosis of Mounier–Kuhn syndrome should be considered in instances of recurrent pneumonia and mucous plugging with or without typical radiologic findings.
