Extralobar pulmonary sequestration as a cause of recurrent pulmonary hemorrhage in a neonate.

Pulmonary sequestration is acystic or solid congenital lung malformation comprised of non functional lung tissue that does not communicate with the normal tracheobronchial tree and has a systemic arterial blood supply. There are two forms of sequestration: intralobar and extralobar. Its treatment is surgical resection. Here we presented a case of premature neonate with extralobar pulmonary sequestration who had respiratory failure and recurrent pulmonary hemorrhage. Following surgery, the patient showed significant clinical improvement.
