A case of prenatally diagnosed fetal neurenteric cyst

The combination of a thoracic cystic mass with vertebral anomalies on prena tal ultrasound suggests a neurenteric cyst. The outcome of such cysts mostl y depends on the extent of the displacement and functional impairment of th e adjacent organs and of the associated central nervous system defects. We present a case of a neurenteric cyst diagnosed on prenatal ultrasound at 34 weeks of gestation which was treated successfully in the early neonatal pe riod.
