Al Hinai","Kevin Petrecca"],"abstract":"Background: Chordoid glioma is a rare brain tumor typically located within the anterior third ventricle. It is a well-circumscribed, non-infiltrative tumor that grows as a mass within the ventricle. Case Description: We present the case of a 50-year-old woman with a chordoid glioma located in the anterior third ventricle. Unusually, MRI revealed an enlarged optic chiasm. Histological sampling of the chiasm revealed tumor invasion. Conclusion: Involvement of the optic apparatus is generally thought to be an imaging feature that can be used to distinguish chordoid gliomas from optic/hypothalamic gliomas. This case provides the first reported exception to this dogma.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/764a7d2b-d3f8-468a-a2e8-23cddc5a6c7f/featured/hero-1782420795113.png","publishDate":"2011-04-28T00:00:00.000Z","doi":"10.4103/2152-7806.80118","categories":["Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/764a7d2b-d3f8-468a-a2e8-23cddc5a6c7f/pdf"}
