Brainstem tumors encompass a heterogeneous population of tumors affecting the midbrain, pons, medulla, and cervicomedullary junction and represent approximately 10–20% of all CNS neoplasms in children (1-4). Diffusely growing gliomas are the most common, representing 75% of brainstem tumors (10, 94). They often have a natural history and a prognosis akin to those of supratentorial glioblastomas, which occur primarily in adults (5, 6).  Focal tumors of the brainstem, by contrast, are encountered less often and are associated with a better prognosis.

The clinical presentation and the behavior of brainstem gliomas are highly variable, depending largely on the tumor’s anatomic location and pattern of growth. Whereas aggressive tumors are associated with a relatively short prodrome of symptoms, indolent lesions may present with an insidious course that will become apparent only after a detailed and careful history is obtained from the parent(s) and patient.

Untreated, these tumors lead to progressive brainstem dysfunction and, ultimately, death.  Unfortunately, most patients with a diffusely growing tumor do not benefit from surgical intervention and rapidly succumb to their disease (6-8).

Key Points

  • MRI imaging modality of choice: MRI is the gold standard for identification of brainstem tumors in children and determination of focality versus diffuse involvement.
  • Surgery effective treatment for focal brainstem gliomas: Focal tumors are often low-grade lesions amenable to surgical resection with good long-term control.
  • Surgery does not affect prognosis of diffuse brainstem gliomas: There is no evidence for a surgical role in the diagnosis and treatment of diffuse brainstem lesions, although improvements in imaging, stereotactic navigation and localization, and surgical techniques have made this conclusion increasingly controversial.
  • Early surgery better tolerated than late: For those lesions for which surgical intervention is deemed appropriate, early intervention is preferable to minimize neurological consequences from prolonged mass effect.
