XANTHOMATOUS POSTERIOR PYRAMID MENINGIOMA IN A 2-YEAR-OLD GIRL

Meningiomas are common lesions in adults but unusual in infancy and me ningiomas located in the posterior cranial fossa are even more rare. M etaplastic changes of meningothelial meningiomas can lead to the rarel y observed xanthomatous form. We describe the case of a posterior pyra mid xanthomatous meningioma in a 2-year-old girl. After detailed neuro radiological evaluation, the histological diagnosis was confirmed with the aid of immunohistochemical evaluation. A critical case evaluation in the light of the more recent literature, the surgical strategy and technique, and an immunohistological hypothesis are reported.
