Abstract
Background and importance: Hemifacial spasm (HFS) caused by a fusiform aneurysm is rare and difficult to treat. We present the first case of successful endovascular flow diversion treatment for HFS due to a fusiform aneurysm.
Clinical presentation: A 46-year-old man suffered from right HFS for 6 months because of a fusiform right vertebral artery aneurysm compressing the root exit zone of cranial nerve VII. He successfully underwent flow diversion, with immediate disappearance of his HFS. Follow-up digital subtraction angiography 3 months after treatment showed complete resolution of the aneurysm.
Conclusion: Flow diversion might be a promising treatment option for HFS due to a fusiform vertebral artery aneurysm.
