title: [Ectasia of the umbilical recess during the antenatal period. 3 case reports].
abstract: Having found three cases of ectasia of the umbilical recess in the antenatal period we decided to review the embryology and the ultrasound of the anatomy of the portal system. We consider that this is a normal anatomic variant of the portal system because the lesion is asymptomatic and regresses spontaneously.
