Abstract Pulmonary sequestration (PS) is a rare congenital malformation that is characterized by the absence of a connection between a portion of the lung tissue and the tracheobronchial tree, with blood supply from arteries throughout the body. Abnormal lung tissue cannot perform the normal gas exchange function. In the absence of timely diagnosis and early intervention, some cases may need labor induction, and some of the infants who survive may develop symptoms in childhood.
