Teaching Video NeuroImages: Infratentorial Multiple Sclerosis Relapse Presenting as Continuous Hemifacial Myokymia
نویسندگان
چکیده
A 26-year-old woman with an 8-year history of untreated multiple sclerosis (MS) presented acute-onset continuous involuntary wavelike movements on the right side her face (video). Neurologic examination revealed right-sided hemifacial myokymia (CFM), no concurrent spasm. MRI documented a new nonenhancing lesion in dorsolateral pontine tegmentum and supratentorial demyelinating lesions (figure, A–D). Symptoms spontaneously resolved 3 weeks later. MS relapses may involve postnuclear facial nerve course within tegmentum, producing ipsilateral CFM.1,2 Strict unilaterality perioral involvement argue against benign eyelid should suggest structural pontic lesion, warranting neuroimaging.

Autoimmune, genetic, viral, and environmental factors have been hypothesized. MS is twice as common in women as in men between the ages of 20 and 50 years. There is no known cure for MS. Current medical treatment helps to prevent new attacks and impro...
