Surgical treatment of coexisting intra and extralobar sequestration in an infant.

Pulmonary sequestration is a rare congenital malformation in which a nonfunctional segment of lung tissue has no communication with the tracheobronchial tree and does not participate in gas exchange. We present a rare case of a 20-month old female with extralobar pulmonary sequestration that was diagnosed at birth. The patient was also found to have a coexisting intralobar sequestration, found during surgery.
