title: Definite and suspected multiple sclerosis in children: long-term follow-up and magnetic resonance imaging findings.
abstract: Twenty-five children at the ages of 3 to 18 years with an initial diagnosis of acute disseminated encephalomyelitis were followed in the Clinic of Child Neurology for a period of 2 to 8 years. In 10 children, there were data for clinically definite or laboratory-supported definite multiple sclerosis. The other 15 children in our study were considered as having suspected multiple sclerosis. Brain magnetic resonance imaging (MRI) performed in 15 children disclosed multiple hyperintense lesions on T2-weighted imaging in 13 children: 10 with definite multiple sclerosis and 3 with suspected multiple sclerosis. The clinical manifestations did not always correspond to the size and location of the MRI lesions of demyelination. Follow-up revealed normalization of the neurologic examination in 18 patients (72%) and abnormal neurologic findings in 7 patients (28%) (6 children with definite multiple sclerosis and 1 with suspected multiple sclerosis). Magnetic resonance imaging follow-up in children with definite multiple sclerosis disclosed a reduction in the size of the lesions in 3; enlargement or new lesions were established in the other 7 cases, and 2 cases were without clinical signs of new attacks. Correlation was done concerning the findings of the cerebrospinal fluid examination, transcranial magnetic stimulation, evoked potentials, computed tomography, and MRI. The role of MRI for an early diagnosis of multiple sclerosis in children is discussed. The dynamic follow-up of the pathologic changes is of prognostic significance for the course of the disease that could be a definite cessation of the process in acute disseminated encephalomyelitis cases or transition to multiple sclerosis.
