Synopsis

Bronchopulmonary sequestration is a rare congenital abnormality of the lungs consisting of a nonfunctional mass of lung parenchyma that lacks communication with the bronchial tree and, instead, receives its blood supply from the systemic circulation. The vast majority (75%-90%) are intralobar, located within the normal lung and lacking their own visceral pleura, or extralobar, which are found outside the lung. Intralobar sequestrations are typically identified after a patient presents with recurrent pulmonary infections. Extralobar sequestrations are typically identified earlier, often in the prenatal period or during childhood.
