Brainstem Glioma
A rare primary brain tumor arising from glial cells within the brainstem structures (midbrain, pons, medulla).
Full Definition
Brainstem gliomas are primary central nervous system tumors that develop from glial cells within the brainstem, comprising the midbrain, pons, and medulla oblongata. These tumors are particularly challenging to treat due to their location in critical neural structures that control vital functions. In clinical documentation, editors must distinguish between focal brainstem gliomas (which may be amenable to surgical intervention) and diffuse intrinsic pontine gliomas (DIPG), which carry a poor prognosis. The term requires careful usage as it encompasses multiple distinct entities with vastly different treatment approaches and outcomes.
Usage
Usage note: Distinguish from DIPG, which is a specific subtype with distinct prognosis.
