目的探讨中颅凹海绵状血管瘤的诊断和伽玛刀治疗。方法16例中颅凹海绵状血管瘤,直径3~4 cm,行伽玛刀治疗,7例紧邻视神经的较大的海绵状血管瘤,半年后再次伽玛刀治疗。结果随访2~4年,11例临床症状改善,随访未见病灶体积变化。5例临床症状消失,病灶体积明显缩小。结论伽玛刀对中颅凹海绵状血管瘤是一种安全、微侵袭、有效的治疗方法。 Objective To investigate the diagnosis and gamma knife radiofrequency of cavernous hemangiomas. Methods Sixteen cases of cavernous hemangioma with a diameter of 3 ~ 4 cm were treated with gamma knife radiosurgery and seven cases with large cavernous hemangiomas adjacent to optic nerve. Six months later, gamma knife treatment was performed again. Results Follow-up 2 to 4 years, 11 cases of clinical symptoms improved, follow-up no change in the volume of lesions. Five cases of clinical symptoms disappeared, lesion volume was significantly reduced. Conclusion Gamma knife is a safe, minimally invasive and effective treatment for cranio-cavernous hemangiomas.
