Anterior Encephalocele Associated With Subependymal Nodular Heterotopia, Cortical Dysplasia and Epilepsy: Case Report and Review of the Literature

Eur J Paediatr Neurol. Sep-Nov 2006;10(5-6):227-9. doi: 10.1016/j.ejpn.2006.08.010. Epub 2006 Oct 10.


The presence of subependymal nodular heterotopia and cortical dysgenesis has been infrequently reported in patients with encephalocele. The majority of these patients were found to have posterior encephaloceles. We report a case of a Hispanic female with a frontoethmoidal encephalocele who developed epilepsy at 15 years of age. Magnetic resonance imaging of the brain demonstrated left subependymal nodular heterotopia, partial agenesis of the corpus callosum and left fronto-temporal cortical dysplasia with polymicrogyria. This case illustrates the association of anterior encephalocele with subependymal nodular heterotopia, cortical dysplasia and epilepsy. It underscores the importance of screening for intracranial abnormalities in patients with anterior encephalocele.
