Pulmonary sequestration is the term used to describe a rare embryonic non-functional lung tissue which has no bronchial communication with the normal tracheobronchial tree. In this study, we reviewed a patient who was treated with embolization as a conservative treatment with a coil first, and after three months underwent excision of extralobar sequestration via right thoracotomy because of his continuing complaints of hemoptysis. We conclude that the embolization can be a conservative treatment option, and the definitive treatment of pulmonary sequestration is surgical resection to avoid destruction of the normal pulmonary parenchyma due to infection.
