Correlation of clinical improvement with pontine lesions in opsoclonus-myoclonus syndrome.
In a case of acute disseminated encephalomyelitis displaying opsoclonus-myoclonus syndrome, magnetic resonance images (MRI) disclosed pontine lesions involving part of the pontine paramedian reticular formation and the raphe nucleus. Shrinkage of the lesions correlated with the patient's clinical state. This observation supports the hypothesis that a pontine lesion can cause opsoclonus-myoclonus syndrome.
