Abstract
Introduction: Tumors of the central nervous system are the most common group of solid neoplasm in children and account for 20% to 25%. They are common in Sub-Saharan countries, despite the insufficiency of histological diagnosis. No study has been performed concerning the pediatric brain tumors in the Republic of Congo. The aim of this study was to describe the conditions of neurosurgical management of pediatric tumors in Brazzaville. Materials and Methods: We performed a retrospective and descriptive study, from January 2014 to December 2017 (48 months), into the neurological unit of the surgical department of Brazzaville. We included all patients aged from 17 years old and below, hospitalized for a brain tumor. Results: We have identified 11 cases of brain tumors. The average age was 8.1 ± 4.3 years old, a sex ratio of 0.57. Ten out of the eleven patients of our series have intracranial hypertension. We found six cases of infratentorial tumors and five of supratentorial location. Only three cases had histology. Ten patients were operated, limited by ventriculoperitoneal shunt in 6 cases, surgical resection in three cases, biopsy in one case. There were no possibilities of radiotherapy and chemotherapy during this period of study. Conclusion: A multidisciplinary team must be organized to improve the management of pediatric brain tumors in our context. Histological diagnosis and possibilities of radiotherapy are imperatively needed.

The epidemiological profile of pediatric brain tumors has been poorly described in Sub-Saharan countries
Summary
Tumors of the central nervous system are the most common group of solid neoplasm in children and account for 20% to 25%. They are common in Sub-Saharan countries, despite the insufficiency of histological diagnosis. No study has been performed concerning the pediatric brain tumors in the Republic of Congo. The aim of this study was to describe the conditions of neurosurgical management of pediatric tumors in Brazzaville. We included all patients aged from 17 years old and below, hospitalized for a brain tumor. Important factors that have contributed to improving the long-term survival of children with brain tumors include advances in neuroimaging, histopathology, neurosurgery, and radiotherapy, associated with chemotherapy [3]. Some types of brain tumors may be completely resected, many cannot be removed without a considerable degree of morbidity [1]
