Facial hemangioma and cerebral corticovascular dysplasia: a syndrome associated with epilepsy.

The authors performed imaging studies in two children with epilepsy and congenital facial hemangioma. The first patient had dysplastic pericallosal arteries and frontal polymicrogyria. In the second patient, dysplastic arteries and dysplastic cortex lined the interhemispheric fissure, the dysplastic cortex bridging across the midline, which resulted in holoprosencephaly. Abnormal cortical development may underlie epilepsy in children with facial hemangioma.
