Successful Treatment of Epilepsy by Resection of Periventricular Nodular Heterotopia

���������������������������������������������������������������������� ������������-����� ������� � We report on a case of successful surgical treatment of drug‑resistant epilepsy associated with a soli‑ tary lesion of periventricular nodular heterotopia (PNH. In the reported patient intracranial ictal electroencephalography disclosed that seizures did not originate from the heterotopic nodules. However the seizures were completely suppressed by lesionectomy of PNH alone. Epileptogenesis associated with PNH likely involves a very complex network between PNH and the surrounding cortex and the disruption of this network may be an effective means of curing intractable PNH‑associated epilepsy.
