, or spread, to affect another part of the body.
The cause is still unknown. Researchers have not found any direct genetic link. Children irradiated for tinea capitis
have been found to have an increased risk for other central nervous system tumors, such as meningiomas, gliomas, and nerve sheath tumors, but not necessarily tumors of the brain stem.
Signs and symptoms
Common symptoms include, but are not necessarily limited to:
- Lack of facial control, (droopy eyelids)
- Double vision
- Headache or headache that gets better after vomiting
- Nausea and vomiting
- Weakness and fatigue
- Balance problems
Symptoms can develop slowly and subtly and may go unnoticed for months. In other cases, the symptoms may arise abruptly. A sudden onset of symptoms tends to occur with more rapidly growing, high-grade tumors.
Neuroimaging, such as MRI, is the main diagnostic tool for brain stem gliomas. In very rare cases, surgery and biopsy are performed.
