1996). Congenital diarrhea is a severe disorder revealed by profuse neonatal diarrhea: while a chloride diarrhea may be diagnosed by measuring chloride concentration in the amniotic ﬂuid, there is no biological marker for the diagnosis of sodium diarrhea (Fell et al. 1992) or of congenital microvillous inclusion disease that is always lethal post natally (Kennea et al. 2001). In fact, in these diseases, the whole small and large bowel is dilated and ﬂuid-ﬁ lled, without transition zone and with polyhydramnios (Fig.
B b Malrotation is observed in 80% of patients with megacystis-microcolon-intestinal hypoperistalsis. To detect it constitutes a main diagnostic argument. Heterotaxia syndromes (polysplenia and asplenia) are characterized by a failure in development of body symmetry, a severe congenital heart disease and a frequent associated intestinal malrotation. It is a disorder or organogenesis from the 5th to 6th weeks. Asplenia is associated to right isomerism with bilateral tri-lobed lungs and anomalous pulmonary venous return.
2004). MRI has high sensitivity for demonstrating the meconial character of ascitic ﬂuid (Fig. 49). A large mass, with slightly echodense content and calciﬁed wall is characteristic of meconium pseudo cyst (Fig. 50). When it is echofree at US, it appears meconial on MRI (Fig. 51) (Veyrac et al. 2004; Wong et al. 2006). Imaging provides decisive arguments for predicting neonatal surgery: persistent ascitis, large meconial pseudo cyst, dilated small bowel proximal-to a mechanical obstruction. At the opposite, prenatal follow-up demonstrates reliably the intra uterine recovery: progressive disappearance of the meconium cyst (Veyrac et al.
