A rare tale of an extralobar pulmonary sequestration as a cause of hemoptysis not often contemplated: a case report

A rare congenital malformation of the respiratory tract, bronchopulmonary sequestration (BPS), may present symptomatically early on in childhood or adolescent years. Adult BPS is typically an incidental finding found on thoracic imaging. There are currently four known types of BPS. Intralobar sequestrations (ILSs) are the most common of them and the most commonly reported form in literature. In our case report, we report of a healthy adult female who presented with hemoptysis that resulted in the diagnosis of the rarest form of BPSs; extralobar sequestration (ELS). One that is not commonly described in literature, especially of one reported in late adulthood. This case report aims to educate and elude clinicians to this rare cause as a differential and guidance on its investigation and management.
