Overview
Classification
- The term brain stem glioma is a generic description that refers to any tumor of glial origin arising in the brain stem, inclusive of the midbrain, pons, and medulla. The following two histologies predominate:
- Diffuse (infiltrating) astrocytomas centered in the pons, also called diffuse intrinsic pontine glioma (DIPG).
- Pilocytic astrocytomas, which occur throughout the brain stem.
- Also, brainstem gliomas can be divided into 3 distinct anatomic locations:
- Diffuse intrinsic pontine
- Tectal
- Cervicomedullary
