Abstract: Bronchogenic cysts are benign congenital aberrations belonging to the spectrum of digestive duplications. Intrathoracic forms are the most common and are essentially mediastinal along the tracheobronchial axis in 2/3 of the cases, but can also occur in the lung, pericardium and diaphragm. They are characterized by clinical and radiological polymorphism and pose a differential diagnosis with other cystic lesions, including hydatid cysts in highly endemic countries hydatid. Surgical resection is required for all suspected bronchogenic cysts and must include a complete excision of the cyst either to confirm the diagnosis and to prevent complications. We report three cases illustrating the different clinical presentations of intrathoracic bronchogenic cysts and their therapeutic management.Abstract: Bronchogenic cysts are benign congenital aberrations belonging to the spectrum of digestive duplications.
