【摘要】 目的:探讨磁源性影像(MSI)对脑海绵状血管瘤(CA)伴发癫痫患者的癫痫灶定位价值,为癫痫外科手术提供依据。方法:对13例脑CA伴发癫痫的患者进行了MRI和MSI检查。观察CA与MSI所确定的癫痫灶之间的位置关系。所有13例患者均经手术治疗。结果:13例患者中,11例CA位置与MSI所确定的癫痫灶位置距离<2cm,2例>2cm。按照Engel分级标准,所有患者均为1级,术后(6～53个月)随访12例患者术后癫痫未发作,1例癫痫发作1次。结论:MSI能明确CA与癫痫灶之间的位置关系,对术前制定手术计划有重要意义。更多还原

【Abstract】 Objective: To evaluate the value in localizing the epileptic focus by magnetic source imaging (MSI) in patients with cavernous angioma (CA) and seizure. Methods: MRI and MSI examination were proceeded in 13 patients with CA and had epilepsy. To observe the relationship of epileptic focus determined by MSI with the location of the CA, all of the 13 patients were operated on. Results: The distance of the location between the epileptic focus identified by MSI and the CA was less than 2cm in 11 cases and more than 2cm in 2 cases. According to Engel classification of epilepsy, all the patients achieved Engel Class 1 outcomes. In 12 cases was seizure free for 6~53 months after operation. One patient had only 1 seizure episode after operation. Conclusion: MSI could define the relationship between the epileptic focus and the location of the CA. The results of MSI have much value to make the surgical plan before operation.更多还原
