Meningiomas correspond to 1% - 4% of primary intracranial tumors in pediatric group, with their incidence raising according to age. There is not gender prevalence, in spite of some authors describe a male tendency opposed to female one in adulthood. At present study we describe two cases of pediatric meningiomas reviewing clinical, radiological and histological aspects of these lesions. The authors review also treatment options and prognosis of childhood meningiomas. A two-year-old boy was admitted with seizures. Computerized tomography showed a right parietal lesion, which was totally resected. Histological features were compatible with meningioma. After 17 months the child is doing well, with no deficits or seizures. The second case is a 12-year-old girl, with a headache complain. During investigation, a CT revealed a right frontal lesion. She was operated under a right frontal craniotomy with total tumor resection. Nowadays she is asymptomatic, 20 months after surgery. Despite meningiomas in pediatric group are uncommon; they should be included in differential diagnosis list of expansive intracranial lesions of childhood.
