Abstract
Cervicomedullary and dorsally exophytic brain stem tumors are surgically accessible and treatable neoplasms that must be distinguished as a specific subset of brain stem gliomas. Brain stem gliomas account for only 10% to 20% of all pediatric brain tumors, and the diffuse neoplasm has been thought of historically when describing these tumors. The focal dorsally exophytic brain stem and cervicomedullary glioma constitute about 10% to 15% of all childhood brain stem tumors. These neoplasms have a distinct clinical presentation, distinct imaging characteristics, and a more favorable prognosis than diffuse brain stem gliomas. This article outlines the present management of cervicomedullary and dorsally exophytic neoplasms.
