Hemispherectomy with corpus callosotomy in pediatric Lennox Gastaut Syndrome associated encephalomalacia cyst: The first case in Indonesia


 Lennox-Gastaut syndrome (LGS) is a form of severe epileptic encephalopathy in children. LGS with encephalomalacia cysts rare We report six-year-old mentally retarded boy who was referred for an intractable seizure. Seizures were tonic, atonic, and dialeptic frequency. EEG showed generalized SSW discharges 1.5-2 Hz, polyspikes, burst suppression typical LGS. Head MRI cyst the right subcortical temporoparietal lobes hemiatrophy cerebral hemisphere. He already treated three antiepileptic drugs, but seizures persisted. The patient then performed hemispherectomy corpus callosotomy. It resulted good response. A combination callosotomy could be promising this epilepsy disease. Seizure reduction achieved cognitive improvement hemiparesis.
