Abstract

A Sixty-one-year-old man was admitted to our hospital because of generalized convulsion. He had suffered from intractable epilepsy for 26 years. CT and MRI showed the right frontal cavernous angioma. On operation, intraoperative electrocorticography was performed after lesionectomy including surrounding glial scar and hemosiderin laden tissue. It showed epileptiform potentials in neighbor gyrus of the lesion. Because the removed sphere would be so broad, and we performed multiple subpial transection (MST). After MST, depression of background electrical activity and disappearance of spike discharge are seen. One and half year after operation, seizure was controlled by only phenobarbital administration.

摘要

一名61岁男性因全身性惊厥入院。他患有难治性癫痫26年。CT和MRI显示右侧额叶海绵状血管瘤。手术中，在切除病变包括周围胶质瘢痕和含铁血黄素沉着组织后进行了术中皮质脑电图检查。结果显示病变相邻脑回存在癫痫样电位。由于切除范围较大，我们进行了多处软膜下横切术（MST）。MST后，背景电活动降低，棘波放电消失。术后一年半，仅通过服用苯巴比妥就控制了癫痫发作。
