A 46-year-old female patient with a history of chronic cough and sputum emission since the age of fourteen was admitted for right chest pain with purulent sputum. She had no history of tobacco smoking or noxious fume exposure. No past history of tuberculosis was found. On physical examination, she had bilateral crackles at the lower field of both lungs. The chest x-ray showed dilation of the tracheal clarity and bilateral bronchiectatic lesions in the bases (Fig. 1). The routine blood analysis and blood gas analysis were within normal rates. The pulmonary functions tests were within normal limits (FVC = 2.45L (85%), FEV1 = 2.22L (90%) and FEV1/FVC = 91%). For further investigation, a thoracic Computed Tomography was ordered. It disclosed dilation in the trachea and in the main bronchi along with cystic bronchiectasis in both lung bases. Bronchoscopy confirmed the presence of an irregular dilation of the bronchial wall of the trachea and stem bronchi with exaggerated collapsibility upon cough or expiration along with abundant secretions. There was no growth on culture tests of the aspirated bronchial secretions. The diagnosis of tracheabronchomegaly was made. The patient was treated with antibiotics (amoxicillin-clavulanic acid) and chest physiotherapy. She was advised Pneumococcal and Influenza vaccination. The course was marked by the occurrence of moderate infectious episodes that did not requiring hospitalization. After twelve years of follow up, a control CT scan revealed multiple tracheal diverticulain addition to the dilation of the trachea (42 mm) and the main bronchi (Right = 22 mm, Left = 24 mm) and the pre-existent bronchiectasis (Fig. 2. The pulmonary function showed a mild obstructive ventilatory deficit was found FVC = 1.89L (73%), FEV1 = 1.34L (62%) and FEV1/FVC = 71%. Otherwise, the patient was clinically stable.
