Pulmonary Sequestration

Pulmonary sequestration is a congenital abnormality consisting of a cystic or solid mass of non-functioning tissue. The tissue consists of lung tissue that is separated from the bronchus (airway). It may be associated with other congenital anomalies.


  • Intrapulmonary
    • Usually diagnosed later in childhood or adolescence, but it can present early
    • Recurrent infections are the most common problem
    • Cystic masses can compress normal lung tissue
  • Extrapulmonary
    • Most often discovered in infancy, but it can be found coincidentally
    • Infants may present with chronic cough or respiratory distress
    • May have no symptoms
    • Are often associated with other anomalies


  • Persistent dry cough
  • Recurrent infections
  • Respiratory distress
  • No symptoms


  • Intrapulmonary
    • Complete resection of the lobe of the lung is the most common treatment
    • Partial resection of the lobe of the lung, with removal of only the sequestration, may be possible
  • Extrapulmonary
    • Resection of the lesion is generally sufficient
