目的通过对比眶颅沟通性肿瘤伽玛刀(GKS)治疗前后MRI表现,探讨MRI对评估GKS治疗效果及预后的价值。方法回顾性分析30例眶颅沟通性肿瘤患者GKS治疗前及治疗后MRI表现,随访时间为6个月。结果 30例均为单眼病灶,左眼18例,右眼12例。30例均行增强MRI扫描,肉眼观察呈轻至高度强化改变。GKS治疗6个月后,肿瘤缩小14例(46.67%),无变化12例(40.00%),增大4例(13.33%),局部有效控制率为86.67%;临床症状好转15例(50.00%),无变化10例(33.33%),恶化4例(13.33%),死亡1例(3.33%)。结论MRI不仅在眶颅沟通性肿瘤的检查中具有重要意义,而且在GKS疗效评价及预后方面也具有重要参考价值。
Objective To compare the MRI findings of GKS before and after treatment of orbital cranial tumors to evaluate the value of MRI in assessing the therapeutic effect and prognosis of GKS. Methods The MRI findings of GKS before and after treatment in 30 patients with orbital cranioverter tumor were retrospectively analyzed. The follow-up time was 6 months. Results 30 cases were all monocular lesions, 18 cases of left eye and 12 cases of right eye. Thirty patients underwent enhanced MRI scans, which showed mild to severe enhancement with macroscopic observation. Six months after GKS treatment, the tumors were reduced in 14 cases (46.67%), unchanged in 12 cases (40.00%), increased in 4 cases (13.33%), locally effective control rate was 86.67%, and clinical symptoms improved in 15 cases (50.00% ), No change in 10 cases (33.33%), deterioration in 4 cases (13.33%) and death in 1 case (3.33%). Conclusion MRI is not only important in the examination of orbital cranial tumors, but also has an important reference value in the evaluation of GKS efficacy and prognosis.
