Multiple sclerosis in children: clinical, neuroimaging, and neurophysiological correlations.
Four female children with clinically-definite diagnoses of multiple sclerosis (MS) were studied with multimodal evoked potentials (EPs), electroencephalogram (EEG), cerebrospinal fluid (CSF) analysis, computed tomography (CT) and magnetic resonance imaging (MRI). Correlations among the clinical features, neuroimaging and neurophysiological studies were also evaluated. Their ages of the onset ranged from 5 to 11 years. The clinical evolution in the all four MS cases was relapsing-remitting form. MRI studies in three cases showed abnormal demyelinating plaques in the brainstem, cerebellum and white matter of the cerebrum. CT examination, performed in the other MS case, did not reveal hypodensic lesion. Despite that MRI failed to document optical nerve lesions, three cases had abnormal visual evoked potentials (VEPs). Somatosensory evoked potentials (SSEPs) were abnormal in three cases. Brainstem auditory evoked potentials (BAEPs) were abnormal in two cases presenting with signs of brainstem dysfunction. The conclusion was that paraclinical evidences obtained from MRI and multimodal evoked potential studies are of value as an aid in localizing involved areas and detecting silent lesions in children with MS.
