title: Brainstem gliomas.
abstract: Brainstem gliomas, a relatively common form of childhood brain tumor, are highly resistant to therapy. With computed tomography and magnetic resonance imaging, these lesions can be diagnosed with a high degree of reliability. The indications for surgery are unclear. Focal lesions may be amenable to partial resections. Stereotactic approaches can be used for diffuse lesions, but it has not been shown that the information obtained changes the approach to treatment or outcome. Higher dose radiotherapy has been recently used but has not improved survival for most patients. Patients with brainstem gliomas must be stratified into risk groups, and new means of treatment are needed.
