A case of Dandy-Walker malformation associated with occipital meningocele, microphthalmia, and cleft palate.

We present a case of Dandy-Walker malformation associated with occipital meningocele, microphthalmia, and cleft palate. Small numbers of cases of Dandy-Walker malformation with occipital meningocele have been described in the literature, but to our knowledge, non of these also had microphthalmia or cleft palate. This association suggests that time of intrauterine origin of Dandy-Walker syndrome was in the sixth or seventh embryonic week. In the diagnosis, both CT cisternography and direct neurosonography over the occipital meningocele was useful for the demonstration of a posterior fossa cyst which communicated with the fourth ventricle and the occipital meningocele.
