Pulmonary sequestration is a rare congenital (present from birth) malformation where non-functioning lung tissue is separated from the rest of the lung and supplied with blood from an unusual source, often an artery from systemic circulation. Pulmonary sequestrations may be defined as intralobular or extralobular, depending on their location. Symptoms may include a chronic or recurrent cough, respiratory distress or lung infection. Treatment depends on the location and may involve surgery.
