Posterior vault encephaloceles: from antenatal management to post-surgical follow-up-a cooperative study.

Purpose: Encephalocele is a herniation of intracranial structures associated with a skull anomaly. In Western countries, posterior encephaloceles are more common than anterior encephaloceles and may occur in the parietal (parietal encephalocele, PE) or occipital (occipital encephalocele, OE) region. Although those entities are relatively common in pediatric neurosurgery, large clinical series are scarce, and their clinical outcomes are poorly documented in the literature.
