PY - 2015 T2 - Fetology: Diagnosis and Management of the Fetal Patient, 2e AB - Key PointsBronchopulmonary sequestration (BPS) is a mass of nonfunctioning lung tissue that does not communicate with the bronchial tree.Prenatal diagnosis is possible by noting an echodensetriangulararea of tissue, often with an obvious systemic feeding vessel, such as from the descending aorta.BPS can be intralobar (same pleural cover as normal lung) or extralobar (separate pleural cover), and can be intrathoracic or extrathoracic.Main differential diagnosis for intrathoracic BPS includes type III CCAM, teratoma, and diaphragmatic hernia, while the differential for intra-abdominal BPS includes mesoblastic nephroma and neuroblastoma.At least 75% of prenatally diagnosed cases of BPS resolve spontaneously, while those associated with hydrops, pleural effusions, or mediastinal shift have a much worse prognosis.Fetal intervention by means of thoracoamniotic shunting may be an option for cases with coexisting pleural effusions prior to 30 weeks' gestation.For large lesions that persist prenatally, and for those associated with hydrops, delivery should occur in a tertiary care center.Elective surgical excision is recommended for most cases of asymptomatic BPS that persist postnatally.
