We report a retrospective study of 294 cases of dilation of bronchi,brought together in the service of the University Hospital of respiratory diseases Ibn Rochd of Casablanca between January 2002 and January 2015. The mean age was 43 years (14-91 years), with female predominantly in 78% of the cases. The etiological investigation identified a medical history of pulmonary tuberculosis in 104 cases of respiratory infection and a medical history of childhood respiratory disease in 43 cases. The average deadline of consultation is 6 months. The clinical symptomatology were dominated by bronchorrhea in 267cas, dyspnea in 143 cases and hemoptysis in 112 cases. The thoracic imaging objectified dilation of bronchi in 189 cases, located in 100 of the cases and bilateral in 89of the cases. The dilations are cylindrical in 13% of the cases, cystic in 51% of the cases and varicose in 36% of the cases .using a Bronchoscopy, bronchial inflammation was found in 218 cases, as well as a foreign body and a budding tumor in two cases each.Probabilistic antibiotherapy and respiratory physiotherapy are indicated for all our patients.
