What Researchers Did
Researchers presented a case report of a 52-year-old woman with multiple sclerosis who developed neurotoxicity after radiosurgery for a vestibular schwannoma and reviewed existing literature on this risk.
What They Found
The presented patient experienced grade 2 imbalance and new brain MRI hyperintensities 3 months after CyberKnife radiosurgery for a left-sided vestibular schwannoma. A literature review identified 19 other multiple sclerosis patients who developed radiation-induced toxicity following intracranial radiation therapy.
What This Means for Canadian Patients
Canadian patients with multiple sclerosis considering radiosurgery for vestibular schwannoma should be aware of a potentially increased risk of radiation-induced neurotoxicity. Clinicians should carefully weigh treatment options, discussing these risks thoroughly with patients to make informed decisions.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study's primary limitation is its reliance on a single case report and a literature review, which limits the generalizability of its findings.
