    Abstract:
    INTRODUCTION: MR is very important examination of central nervous system in children in the evaluation of differences dependent of sex and age as well as in the diagnostics. Radiological indications are important in many cases to perform a control study, to evaluate a dynamic changes or to establish the diagnosis. THE AIM: The aim of this study was to examine the results of control MRI examination in children with neurologic syndromes. MATERIAL AND METHODS: In the year 2006 control MRI was performed in 22 cases since it was advised after previous MRI examinations in children hospitalized in the Department of Pediatric Neurology UJ CM in Kraków. The group of children aged 4-18 years (mean 12 years) consisted of 14 boys and 8 girls. The commonest clinical diagnoses were epilepsy, encephalopathies, hemiparesis, cranial neuropathies, headache, anizocoria, vertigo, paraparesis and NF I. RESULTS: Repeated MRI in 14 children did not revealed significant changes, independently from clinical changes. In 3 patients positive changes or regres of pathological foci were observed within the subarachnoid hemorrhage. In 3 children MRI revealed progressive changes, within in the child with NFI, and in patient with pyramidolextrapyramidal syndrome which progressed from hemiparesis to quadriplegia and also in a child with disseminated symptoms, such as ataxia, piramidal syndrome and cranial nerve palsies. In 2 other children the repeated MRI helped to establish the final diagnosis. The evolution of neuroradiological changes in the first child with the history of hemiparesis indicated ischemia as a cause of neurological syndrome. The other patient with cranial neuropathies of VII, VIII and XII nerves associated with intellectual impairment was diagnosed with CADASIL only with the help of control MRI examination. CONCLUSIONS: In 9% children the second MRI which helped to analyze evolution of changes was important to establish the final diagnosis. The control MRI examination in 64% children did not revealed significant changes independently of clinical changes, such as recovery or aggravation of symptoms, what explains the decision to repeat MR examination in unclear cases.
