| Abstract: | Cerebral and meningeal involvement in patients with primary extracranial neuroblastoma (NB) is unusual although it is generally present in disseminated disease. The intensification of chemotherapy that has prolonged survival in these children has changed the pattern of relapse presentation, as occurs with isolated central nervous system (CNS) disease. We report 4 patients with secondary CNS metastases. Three infants of 16, 14, and 10 months of age, diagnosed with primary abdominal NB stage 4, presented neuromeningeal metastases during maintenance chemotherapy with seizures and cranial hypertension as the first manifestation. Another 8-year-old patient diagnosed with NB stage 3 presented local relapse with later neuromeningeal metastases. All died in the following 3 months. The possibility of CNS relapse in patients with NB should be considered when neurological symptoms and signs appear. These new relapse forms overshadow the prognosis of these children. © 1996 Wiley-Liss, Inc. |
