Abstract

PURPOSE: Pediatric seizure patients have various etiologies and clinical outcome. To determine patient's treatment and prognosis, the etiology of seizure is important. Brain MRI is one method which shows many information. This study was performed to find out the efficacy of brain MRI in determining the etiology and clinical outcome in pediatric seizure disorder.
METHODS
One-hundred thirty patients with seizures from January, 1996 to December, 1997 had brain MRI performed. All of them except four patients had EEG performed. We observed the initial data on brain MRI, EEG and clinical characteristics of seizure patients.
RESULTS
1) In one-hundred thirty patients, 50 patients (38.5%) had abnormal brain MRI findings. The frequency of abnormal finding was as follows : brain atropy (20), cerebrospinal fluid space dilatation (11), cerebrovascular accident (6), infection (3), cyst (2) and moyamoya disease (2) and others (6). 2) Frequency of seizure, EEG severity, cerebral hemisphere abnormality in brain MRI, and multiple lesions in brain MRI correlated with poor clinical outcome. 3) Severe abnormality of EEG correlated with possibility of abnormal brain MRI finding.
CONCLUSION
Initial brain MRI, EEG and clinical characteristics were good indicators of pediatric seizure patient's clinical outcome.
