[Early echographic diagnosis of omphalocele. 2 case reports and review of the literature].

The authors report two cases of early diagnosis of omphalocele. The first, suspected by ultrasonography at 11 weeks amenorrhea, was associated with a cystic lymphangioma of the neck. In the second case, bearing in mind the past history of interrupted pregnancy and of fetal malformation, the early indication for ultrasonography enabled the diagnosis of an omphalocele associated with anencephaly and abnormal closure of the neural tube. The ultrasonographic discovery of these malformations during the first part of pregnancy enabled vaginal fetal extraction.
