目的探讨脑炎性肉芽肿的伽玛刀治疗效果。方法经MRI检查后采用LEKSELL立体定向仪测定靶灶坐标行伽玛刀治疗。结果本组脑炎性肉芽肿19例,靶灶直径(Z+Y+Z/3)1.0～2.5cm,平均2.0cm,边缘剂量16～18Gy,平均(15.8±1.7)Gy,中心剂量25～36Gy,平均(28.9±2.1)Gy,随访12～24个月:①癫痫发作完全消失或每年偶发1～2次者计为12例;②癫痫发作减少75%者76例。结论伽玛刀是治疗脑炎性肉芽肿的一种安全有效的方法。
Objective To investigate the effect of gamma knife treatment of encephalitis granuloma. Methods After MRI examination, LEKSELL stereotactic apparatus was used to measure the target lesion coordinates and gamma knife treatment. Results In the present study, 19 patients with encephalitis granuloma of this group had a diameter of (Z + Y + Z / 3) of 1.0 to 2.5 cm with an average of 2.0 cm and an edge dose of 16 to 18 Gy with an average of (15.8 ± 1.7) 36 Gy, mean (28.9 ± 2.1) Gy, followed up for 12 to 24 months: ① The seizures completely disappeared or 1-2 cases of sporadic cases were counted as 12 cases; ② The seizure decreased 75% in 76 cases. Conclusion Gamma knife is a safe and effective method for the treatment of cerebral inflammatory granuloma.
