Pulmonary sequestration is defined as a nonfunctioning mass composed of dysplastic lung parenchyma, embryologically Lantern detached from the tracheobronchial tree and receiving its own blood supply from a systemic artery, usually the thoracic or abdominal aorta.It may be intralobar or extralobar depending on the presence of an independent pleural envelope.Extralobar sequestration is a much rarer entity, and diagnosis is usually made antenatally or in early life.Here, we present a Leggings rare case of extralobar pulmonary sequestration in an adult.
