[Pulmonary sequestration: 2 cases (intralobar and extralobar) in surgically treated adults]

We present two cases of pulmonary sequestration, one intralobar and the other extrapulmonary, in young adults. The diagnoses were obtained after surgical resection in both cases. The cases are of interest in that the first (intralobar sequestration) started with massive hemoptysis requiring emergency treatment, and the second (extrapulmonary sequestration) involved an unusual location in the upper mediastinum, requiring surgery by video assisted thoracoscopy.
