Case Discussion

Bronchopulmonary sequestration is a rare congenital malformation of the lower respiratory tract, that has no communication with the bronchial tree. The blood supply usually branches from the thoracic or abdominal aorta.

There are two forms of bronchopulmonary sequestration:

  • Intralobar sequestration is surrounded by normal lung tissue
  • Extralobar sequestration has its own pleural investment
