brainstem glioma
Primary brain tumor arising within the brainstem structures, often requiring specialized treatment approaches.
Full Definition
Brainstem gliomas are primary brain tumors that arise within the midbrain, pons, or medulla oblongata. These tumors present unique challenges due to their location in critical structures controlling vital functions such as breathing, heart rate, and consciousness. The most common subtype is diffuse intrinsic pontine glioma (DIPG), which predominantly affects children and has historically poor prognosis. Unlike tumors in other brain locations, brainstem gliomas often cannot be safely biopsied or resected due to the risk of devastating neurological complications. Treatment typically involves radiation therapy and increasingly targeted molecular therapies. Editorial staff should understand the anatomical specificity and treatment limitations associated with this tumor location.
Usage
Usage note: Spell as one word 'brainstem,' not 'brain stem.' DIPG refers specifically to diffuse intrinsic pontine glioma.
In Context
- "The MRI findings were consistent with a diffuse brainstem glioma involving the pons." — Radiology report
- "Biopsy was contraindicated due to the brainstem glioma's location in eloquent tissue." — Treatment planning note
