Pathology of Bronchopulmonary Sequestration

Dr Sampurna Roy MD




Bronchopulmonary sequestration is the presence of lung tissue (lobes or segments) without a normal connection to the airway system and with vascular supply derived from the aorta or its branches, not the pulmonary artery.

1. Extralobar sequestrations are found most often in infants as abnormal mediastinal masses and in association with other congenital abnormalities.

2. Intralobular sequestrations are found within the lung parenchyma. They are more common in adults and are associated with recurrent infections.
