A patient developed hemilateral tonic spasms associated with a relapse of multiple sclerosis.An area of demyelination in the right internal capsule was observed on a magnetic resonance imaging scan.This lesion was not detectable on a second magnetic resonance imaging scan 10 months after the spasms had ceased.Paroxysmal symptoms in multiple sclerosis may represent transient phenomena related to inflammation in acute plaques. |
