title: [Surgical management of intractable epilepsy in patients with ganglioglioma].
abstract: Long-standing intractable seizures are common manifestation of cerebral gangliogliomas. There is much controversy regarding the most appropriate surgical treatment (lesionectomy vs resection of the epileptogenic cortex with the lesion) for patients with intractable epilepsy associated with gangliogliomas. We reported 2 cases, in which the favorable seizure outcome was obtained following lesionectomy alone. (Case 1) Nine-year-old female developed attack of abnormal sensation in her left upper limb followed by motor seizure in her left limbs since 5 years old. MRI revealed hyperintense tumor in the right medial frontal lobe. Chronic invasive subdural recording showed that ictal onset zone was located in the hand motor area. Following lesionectomy alone, she became free from seizures. (Case 2) Eight-year-old girl had intractable generalized seizure since 6 years old. MRI revealed a cystic tumor in the right parietal lobe. She had multiple spike foci on electroencephalography and magnetoencephalography, and intraoperative electrocorticography failed to reveal the paroxysm. Following lesionectomy, she had good relief with less than one minor seizure per 1-3 months. Thus, lesionectomy, even without resection of the epileptogenic cortex, may improve seizure outcome in patients with ganglioglioma-associated epilepsy.
