目的 探讨颅底沟通性脑膜瘤 患者CT与MRI诊断结果。方法 将2012/1 至2016/1来我院接受治疗的70例经外科 手术及病理确诊的颅底沟通性脑膜瘤患 者纳入本研究。对患者进行CT检查、MRI 检查，观察患者临床表现、肿瘤位置、 肿瘤CT、MRI影像特点、CT、MRI诊断准 确率、CT、MRI诊断对颅底沟通性脑膜 瘤侵犯周围骨质、软组织的诊断符合情 况。结果 两种方法诊断准确率对比，差 异无统计学意义(P＞0.05)。MRI对颅底 沟通性脑膜瘤侵犯周围骨质的诊断准确 率高于CT，有统计学差异(P＜0.05)。 MRI对颅底沟通性脑膜瘤侵犯周围软组织 的诊断准确率高于CT，有统计学差异(P ＜0.05)。结论 颅底沟通性脑膜瘤患者 CT与MRI诊断准确率一致，MRI颅底沟通 性脑膜瘤侵犯周围骨质和软组织的诊断 准确率相对较高。

Objective To explore the result of diagnosis for the patients with communication of the skull base meningioma by CT and MRI. Methods 70 cases of patients with communication of the skull base meningioma were researched. They were tested by CT and MRI. The clinical presentation, tumor location, tumor CT, MRI imaging characteristics, CT and MRI diagnosis, CT and MRI diagnostic accuracy of the communication of the skull base meningioma invade surrounding bone, soft tissue diagnosis accord with conditions were observed. Results There had no significant difference on the diagnostic accuracy rate(P＞0.05). The diagnostic accuracy rate for the patients with base of communication meningiomas invading surrounding bone by MRI were higher than CT(P＜0.05). The diagnostic accuracy rate for the patients with communication of the skull base sex meningioma infringement of the surrounding soft tissue by MRI were higher than CT(P＜0.05). Conclusion It has the same diagnostic accuracy rate for the patients with communication of the skull base meningioma by CT and MRI, the MRI has high rate on communication of the skull base meningioma infringement of surrounding bone and soft tissue.
