[A giant hyperostotic parasagittal meningioma in a child with neurofibromatosis type II (a case report and literature review)]. / Gigantskaya giperostoticheskaya parasagittal'naya meningioma u rebenka s neirofibromatozom II tipa (sluchai iz praktiki i obzor literatury).

Large parasagittal meningiomas, in particular hyperostotic ones, in children are rare and problematic in the differential diagnosis. The literature reports only single clinical cases related to this issue; opinions about the indications, surgical treatment options, and prognosis are contradictory. This paper presents a clinical case of a hyperostotic parasagittal meningioma with intra-extracranial growth in a 10-year-old boy with neurofibromatosis type II significantly worsening the prognosis. We discuss the epidemiological and clinical features of childhood meningiomas and issues of their diagnosis, treatment, and prognosis.
