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.
