Pediatric cystic meningioma: report of three cases.

Three cases of pediatric cystic meningioma are reported. In a review of the literature the authors stress the importance and difficulty of accurate preoperative diagnosis. Cystic meningioma in pediatric patients differs from that in adults in the following respects: higher incidence, predilection for males, shorter clinical history, less specific neuroradiological diagnosis, frequent absence of a dural attachment, prevalence of Nauta type II cystic meningioma, and high incidence of the fibroblastic histotype.
