title: Intradiploic neural heterotopia. A rare calvarial defect.
abstract: Two proved cases of intradiploic neural heterotopia of the skull, a rare cause of calvarial defects, are presented. The literature is reviewed. Common radiographic characteristics include an intradiploic rarefaction, a well-defined margin with or without sclerosis, a lobulated appearance with normal intervening bone, or a cluster of multiple lytic areas with normal bone between them.
