Cervical meningocele associated with subependymal nodular heterotopia.

Heterotopia is a subgroup of migration abnormalities, recognized by arrest of radial migration of neuroblasts. Being a well-known cause for developmental delay, mental retardation, and epilepsy, association of heterotopia with some other conditions has also been proposed. There are several case reports regarding the concurrence of heterotopia and encephalocele; however, no such association has been reported with cervical meningocele. Herein, we present the first case of periventricular nodular heterotopia associated with cervical meningocele. Our case further emphasizes the role of brain MRI in the evaluation of those with neural tube defects. Recognition of possible associated heterotopia is important for planning proper treatment and genetic counseling.
