Abstract
CASE REPORT: An 11-month-old girl had an onset of oculogyric crisis at 2 months and she presented with epileptic spasms and generalized tonic seizures with series formation at 3 months. Her seizures were medically intractable and her development had gradually regressed after that. MRI showed severe lissencephaly in bilateral hemispheres. Interictal EEG showed hypsarrhythmia periodically and sporadic spike waves in the right hemisphere. The generalized tonic seizures began with bi-frontal polyspikes on EEG. Our diagnosis was lissencephaly presenting with West syndrome and generalized tonic seizures. A total callosotomy was performed at 11 months. OUTCOME: Postoperative frequency of seizures decreased prominently and developmental progression was resumed. CONCLUSIONS: This case showed that the corpus callosum may play an important role in some types of symptomatic West syndrome. Corpus callosotomy for treating symptomatic West syndrome should be considered as an option after careful selection and consideration of the timing of surgery.
