title: Continuous hemifacial myokymia as the revealing symptom of demyelinating disease of the CNS.
abstract: Facial myokymia (FM) is an uncommon involuntary movement, disorder of the musculature supplied by the facial nerve and, characterized by spontaneous undulating, vermicular movements beneath the, skin. It has rarely been described as a form of presentation of multiple, sclerosis. We describe a 31-year-old man presenting with continuous, unilateral facial myokymia as the revealing symptom of a demyelinating, disorder of central nervous system. Brain magnetic resonance imaging, showed an ipsilateral pontine T2/FLAIR hyperintensity close to the, postgenu course of facial nerve, suggestive of a segmental demyelination, of facial nerve causing facial nuclear hyperactivity and resulting in FM., Facial myokymia must raise the possibility of MS in adults under the age, of 40.
