Intralobar bronchopulmonary sequestration in an adult: a case report.

Bronchopulmonary sequestration (BPS) is typically a rare congenital disorder characterized by the presence of non-functioning lung tissue. There are two types of BPS: intralobar and extralobar sequestration, where extralobar sequestration can either be intrathoracic or sub-diaphragmatic. In this case report, we present the case of a 70-year-old male with intralobar BPS who presented with recurrent chest infections, and a diagnosis of intralobar pulmonary sequestration was made based on a computed tomography (CT) scan. The diagnosis of intralobar pulmonary sequestration can be delayed as the intralobar type can present with varying imaging findings. A diagnosis can be made based on CT or MRI findings. A CT scan or MRI can show mass or consolidation with or without a cyst. Both CT and MRI can be reliable modalities to identify the arterial supply of the sequestered lung tissue, which is commonly a branch of the descending aorta. Sequestration should be suspected when a posterobasal lung abnormality is supplied by an abnormal artery from the aorta or another systemic artery.
