Their location is subpulmonic and they may develop within the diaphragm or in the periadrenal area. Although most are asymptomatic lesions, the presentation includes respiratory compromise, and repeated infection. The sequestered tissue may be solid or cystic. Identification of a cystic mass in utero suggests the presence of a sequestration, a congenital cystic adenomatoid malformation, or a diaphragmatic hernia. Doppler ultrasound examination will often identify feeding vessels arising from the aorta.
Management includes appropriate antibiotic treatment in cases of infection and surgical removal.
Recent management has included successful arterial embolization. Prognosis is excellent and the ipsilateral lung is usually normal.
