Neurophysiological findings revealed an absent ipsilateral R1 on blink reflex. An MRI showed a dolichoectatic left vertebral artery impinging on the root exit zone of the left facial nerve. Botulinum toxin infections relieved the manifestations of hemifacial spasm. This case demonstrates that MRI/MRA is an essential part of the work-up for hemifacial spasm, and shows that in accordance with the literature, vertebral dolichoectasia is an uncommon cause of hemifacial spasm.}, issn = {0379-5284}, URL = {https://smj.org.sa/content/26/10/1640}, eprint = {https://smj.org.sa/content/26/10/1640.full.pdf}, journal = {Saudi Medical Journal} }
