Radiation-associated xanthomatous meningioma in a child

Radiation-associated meningioma in a child is rare. We report a case of xan thomatous meningioma, a rare subtype even in the adult population, which oc curred in a 10-year-old boy who had undergone irradiation therapy for epend ymoma at the age of 2 years. Histological examination of the tumor revealed a mixture of meningothelial cells and abundant foamy xanthomatous cells, w ith no apparent atypical cellular features. Xanthomatous meningioma associa ted with therapeutic high-dose irradiation in a child has not yet been docu mentcd. Immunohistochemical studies and the clinical course are evaluated w ith a review of the literature.
