Intralobar Bronchopulmonary Sequestrations Associated With Bronchogenic Cyst

Abstract

INTRODUCTION: Extralobar bronchopulmonary sequestrations (ELS) and bronchogenic cysts are pulmonary congenital anomalies arising from ventral foregut malformations. Although uncommon, foregut malformations frequently occur together. Intralobar bronchopulmonary sequestrations (ILS), however, are rarely associated with bronchogenic cysts or other congenital lesions. This phenomenon raises controversy whether the origin of ILS is congenital or acquired. We present three cases of ILS occurring with a bronchogenic cyst, supporting that it is a congenital, not acquired lesion.
