ABSTRACT
Miller-Dieker syndrome (MDS) is characterized by facial abnormalities and lissencephaly and is caused by a microdeletion in the region containing the LIS1 gene at chromosome 17p13.3. We report a case in which postnatal neuroimaging revealed severe lissencephaly. A 9-month-old boy presented with infantile spasms syndrome. Because of the refractory course of seizures and continued poor vitality, total corpus callosotomy was performed at 28 months of age. Intraoperative electroencephalogram (EEG) showed that the bilateral synchronous epileptiform discharges disappeared immediately after the disconnection. Postoperatively, the epileptic spasms (ES) in clusters disappeared, and single ES followed by focal seizures became the main symptom. The patient smiled more and became more responsive to stimuli. Postoperative scalp interictal EEG showed desynchronized multifocal spike and wave discharges with a marked decrease in the bilateral synchronous spike and wave discharges. Our findings suggest that the corpus callosum is involved in the mechanism ES in clusters in MDS-associated lissencephaly, and total callosotomy could be a therapeutic option.
