[Subependymal pseudocysts in the fetal brain revealing Zellweger syndrome].
Prognosis of subependymal pseudocyst is poor when associated with other anomalies. They can be caused by infectious, vascular, chromosomal or metabolic disorders but are rarely described in the antenatal period. We report the prenatal diagnosis of subependymal pseudocyst by MRI after prenatal detection of isolated ventriculomegaly at 23 weeks gestation. The karyotype was normal. The diagnostic of Zellweger syndrome was suspected and was confirmed after birth by metabolic studies. Metabolic studies with culture of chorionic villus cell is indicated for subsequent pregnancies.
