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 investigate the CT and MRI diagnosis of patients with meningioma of skull base. Methods From January 2012 to January 2016, 70 patients with surgically and pathologically diagnosed intracranial meningioma were included in this study. The patients were examined by CT and MRI, and the clinical manifestations, tumor location, tumor CT, MRI features of CT, MRI diagnostic accuracy, CT, MRI diagnosis of the surrounding skull base communicating meningiomas invasion of bone and soft tissue In line with the situation. Results There was no significant difference in diagnosis accuracy between the two methods (P> 0.05). The accuracy of MRI in diagnosing peripheral meningioma of the skull communicating with meningiomas was higher than that of CT (P <0.05). The diagnostic accuracy of MRI on the surrounding soft tissue of communicable intracranial meningioma was higher than that of CT (P <0.05). Conclusions The diagnostic accuracy of CT and MRI in patients with intracranial meningioma of skull base is consistent, and the diagnostic accuracy of surrounding skull and soft tissue in communicating skull base communicating meningioma is relatively high.
