What Researchers Did
Researchers reported a case of a 16-year-old girl who developed severe steroid-resistant brain oedema eight months after gamma knife radiosurgery for a frontal arteriovenous malformation, and was then treated with HBOT.
What They Found
The patient presented with facial palsy, arm numbness, headache, and vomiting. After HBOT, neurological symptoms resolved completely. Follow-up imaging showed serious improvement in the brain oedema that had been resistant to steroids.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A single case report cannot establish efficacy; this outcome may reflect natural disease course or other factors, and systematic evidence is lacking.
