[Prenatal recognition of omphalocele (author's transl)].

The prenatal diagnosis of omphalocele is reported. The characteristic signs in the ultra-sound scan were a small trunk, an angulation of the spine and mass adjacent to the absomen of the fetus. By x-ray amniography the ultra-sound findings were confirmed at further abnormalities outlined. The alpha fetal protein levels in the maternal serum and in the amniotic fluid are markedly elevated.
