title: [Secondary metastatic neuromeningeal localization of neuroblastoma in children].
abstract: In order to evaluate the frequency, clinical and radiological aspects and prognosis of central nervous system metastases in children's neuroblastoma, the 258 children presenting with neuroblastoma, and registered from January 1982 to August 1987, were studied. Among them, 7 patients (2.7%), of which 6 had an initially metastatic neuroblastoma, presented with a secondary neuro-meningeal involvement. Parenchyma involvement (4 cases) occurred after a mean period of time of 21 months and marked the relapses. The disease recurs later on, even when locally controlled by surgical excision and local irradiation. Meningeal involvements (3 cases) occurred after a mean delay of 12.7 months, in patients with full tumoral evolutivity, and were responsible for rapid death. The clinical presentation of these metastases differs from that in adults by the rapidity of setting up of the signs and the frequency of intracranial hypertension. CT scan allows approaching diagnosis in the majority of the cases. These data are compared with those in the literature, where 30 cases were reported: they show a high patients' average age and the worse prognosis.
