title: Dandy-Walker cyst associated with occipital meningocele.
abstract: Two cases of Dandy-Walker cyst associated with occipital meningocele are presented. Only 9 cases with such association have been described in the literature. In our patients computed tomography clearly demonstrated direct communication of a posterior fossa cyst with an occipital meningocele at one end and with the fourth ventricle at the other. Occipital meningocele might simply be an expression of increased intracystic pressure in Dandy-Walker cyst in embryonic life, or such association might suggest its morphogenetic situation during embryogenesis.
