Background:
Triphasic waves (TWs) on electroencephalograms (EEGs) have predominantly been observed in adults, often associated with Creutzfeldt‒Jakob disease and metabolic encephalopathy. However, TWs have also been linked to various nonmetabolic and structural abnormalities. Additionally, reports of TWs in children are rare.
Case Presentation:
We present the case of an 8-year and 5-month-old boy with basal ganglia lesion who exhibited TWs in the local C3 lead on electroencephalography. Subsequent EEGs revealed no additional abnormalities. During the follow-up at 1 year and 8 months, there was no significant change in the patient's condition.
Conclusion:
Triphasic waves can occur in children with basal ganglia lesions, but their underlying causes may differ from those previously reported. Further research is needed to elucidate the mechanisms and clinical significance of TWs in pediatric patients.
