A 39-year-old woman was admitted to hospital because of a sensory hemisyndrome caused by a contrast-enhancing demyelinating lesion of the cervical cord. MRI, CSF examination and subsequent clinical and neuroradiological follow-up led to the diagnosis of multiple sclerosis. The patient had noticed an involuntary contraction of a small muscle fascicle on the right side of the chin for a year. Electromyographic and video recordings confirmed the synkinesis between the orbicularis oculi and lower facial muscles, a finding distinct from the myokymic discharges reported in multiple sclerosis and more similar to the synkinesis associated with hemifacial spasm.

Abstract

A 39-year-old woman was admitted to hospital because of a sensory hemisyndrome caused by a contrast-enhancing demyelinating lesion of the cervical cord. MRI, CSF examination and subsequent clinical and neuroradiological follow-up led to the diagnosis of multiple sclerosis. The patient had noticed an involuntary contraction of a small muscle fascicle on the right side of the chin for a year. Electromyographic and video recordings confirmed the synkinesis between the orbicularis oculi and lower facial muscles, a finding distinct from the myokymic discharges reported in multiple sclerosis and more similar to the synkinesis associated with hemifacial spasm.
