A case of dysembryoplastic neuroepithelial tumor in the left insular cortex manifesting with intractable seizures is presented. The multichannel magnetoencephalography (MEG) localized equivalent current dipoles of epileptic discharges at the cerebral cortex adjacent to the tumor. The total removal of the tumor resulted in complete disappearance of seizures. This case demonstrated that multichannel MEG was useful in the three-dimensional localization of irritative zone in the concealed cortices such as inside the sylvian fissure.
本文报告一例位于左侧岛叶皮质的胚胎发育不良性神经上皮肿瘤,表现为顽固性癫痫发作。多通道脑磁图(MEG)将癫痫放电的等效电流偶极定位于肿瘤附近的大脑皮质。肿瘤全切后癫痫发作完全消失。该病例表明,多通道MEG有助于对诸如外侧裂内等隐蔽皮质区的激惹灶进行三维定位。
