OBJECTIVE: Intracranial meningiomas are very rare in children, comprising only 0.4 to 4.1% of pediatric tumors and only 1.5 to 1.8% to all intracranial meningiomas. The goal of this study of pediatric meningiomas was to establish their epidemiological profile as well as their clinical and radiological features, to assess the long-term outcome, and compare this result with adult meningioma.
PATIENT AND METHODS: We conducted a retrospective study from June 1983 to June 2007; during this period 521 patients underwent surgery for primary meningioma at the Rabat Hospital, Department of Neurosurgery. Twenty-one patients were under 16 years of age (4%). The clinical charts and imaging data were reviewed.
RESULTS: The mean age was 10.3 years (range: 2 to 16 years), with 13 boys and eight girls. In one patient a neurofibromatosis was associated. The mean delay to diagnosis was 4.6 months (range: 1 to 12 months). The most common clinical sign was raised intracranial pressure (90%). Of the meningiomas diagnosed, 47% were convexity meningiomas while 24% were parasagittal and 19% were skull-base meningiomas; in two cases (9.5%) the location was intraventricular. The mean tumor diameter was 6.6 cm (range: 3 to 10 cm). A large cystic component was found in 24% of the cases. Surgery achieved a Simpson grade I resection in 47%; 62% of the tumors were grade I and 24% were grade II based on World Health Organization pathological classification. The mean follow-up period was 33 months (range: 6 to 120 months). The recurrence rate was 33%.
CONCLUSION: Pediatric meningiomas are larger than those found in the adult population; there is a male predominance with high incidence of a cystic component and high-grade meningiomas, thus explaining the increased recurrence rate despite the multimodal treatment.
