Glial heterotopias of the nose: a report of two cases.

Two neonates are presented who had glial heterotopias of the nose, one with and the other without intracranial connections. It is important to distinguish these malformations from nasofrontal encephaloceles in order to avoid inadvertent exposure of the brain during surgical removal of the mass lesions. The distinction between them may not be clear clinically because of their similar pathogenesis.
