Congenital cystic lesions of the lung in fetuses are rare. The most common malformations of the lower respiratory tract are congenital cystic adenomatoid malformation and bronchopulmonary sequestration. With the increased use of obstetric ultrasound, cystic lung lesions are detected more often antenatally, which allows for proper planning of peripartum and neonatal management. This article discusses a range of diagnostic and management options.
