title: Antenatal and postnatal findings in intra-abdominal pulmonary sequestration.
abstract: A hyperechoic mass in the right upper quadrant of the abdomen was demonstrated in a fetus by antenatal ultrasonography (US) at 20 and 33 weeks' gestation. Postnatal US, myelography and computed tomography were performed preoperatively; the findings were judged consistent with neuroblastoma. Surgical excision and pathological examination revealed bronchopulmonary sequestration.
