Meningioma gigante en paciente pediátrico: reporte de caso y revisión de la literatura

Abstract

Meningiomas arise from the meningeal coverings of the central nervous system. Pediatric meningiomas are infrequent tumors accounting for 0.5% to 5% of central nervous system tumors in the pediatric age group, being the most common nonglial primary brain tumor. There is no confirmed evidence for the pathogenesis of pediatric meningiomas. Usually they are located in the supra or infratentorial convexity, intraventricular and skull base. The clinical presentation of pediatric meningiomas is nonspecific, varies according to its location and size. Meningiomas subtypes in childhood are mainly WHO grade I meningothelial (32%). The treatment of choice is a complete tumor resection (Simpson I) to prevent recurrence and improve prognosis. We present a case of a 9-year-old female child with a large frontal meningioma, a prevalence report in our institution as well as a review of the current literature of this pathology.
