目的:探讨立体定向囊内放射治疗囊性和囊实性颅咽管瘤的方法和疗效。方法:对12例囊性和囊实性颅咽管瘤的囊性部分行CT、MRI引导立体定向吸除囊液、注入胶体磷酸铬,待瘤囊缩小远离视神经等重要结构后,施行伽玛刀治疗。结果:全部病例经手术排出囊液后临床症状迅速改善。经囊内放疗后2-36个月随访12例患者,CT、MRI扫描显示5例患者瘤囊持续消失,临床症状消失,恢复正常的生活和学习;5例患者肿瘤显著缩小,症状持续改善;2例肿瘤无明显改变;无死亡病例。结论:CT、MRI引导立体定向放射治疗囊性颅咽管瘤安全、有效。
Objective: To investigate the method and efficacy of stereotactic intracapsular radiotherapy for cystic and cystic craniopharyngiomas. Methods: Cystic part of 12 cases of cystic and cystic craniopharyngiomas were treated with CT and MRI guided stereotactic removal of cyst fluid and colloidal chromium phosphate. After the cysts were reduced to be far from the important structures such as the optic nerve, gamma Knife treatment. Results: The clinical symptoms of all cases were rapidly improved after the operation of draining cyst fluid. Twelve to 36-month follow-up was performed after intracapsular radiotherapy. The CT and MRI scans showed that the tumor capsule disappeared continuously, the clinical symptoms disappeared and the normal life and learning returned to normal. The tumors in 5 patients were significantly reduced and their symptoms continued to improve. No significant changes in 2 cases of tumor; no deaths. Conclusion: CT and MRI guided stereotactic radiotherapy for cystic craniopharyngioma is safe and effective.
