Retrosellar intracranial extracerebral glioneuronal heterotopion: case report.
We report the case of an 18-year-old woman with an intradural retroclival retrosellar glioneuronal heterotopion. At the time of surgery, a well circumscribed pale-tan mass was identified posterior to and distinct from the posterior pituitary. Pathologic examination showed disorganized, non-neoplastic glial tissue characteristic of glioneuronal heterotopia. To our knowledge, this is the first report of such a lesion in this location.
