MRI和CT诊断在颅底沟通性脑膜瘤患者中的应用价值

The application value of MRI and CT diagnosis in patients with skull base communicating meningioma

目的 探讨MRI和CT诊断在颅底沟通性脑膜瘤患者中的应用价值。方法 选取延安大学附属医院2016年3月至2024年3月收治的98例颅底沟通性脑膜瘤患者实施研究,对患者CT、MRI诊断资料及临床资料进行回顾,分析CT、MRI在疾病诊断,肿瘤对周围骨质、软组织结构侵犯的价值。结果 98例患者在颅底位置内外沟通,其中62例患者呈现颅眶沟通,26例患者呈现颅鼻沟通,10例患者呈现颅颈沟通。CT诊断在颅底沟通性脑膜瘤的定性诊断中准确率达到85.71%(84/98),MRI诊断的定性诊断准确率达到87.76%(86/98),两组对比差异无统计学意义(P>0.05)。CT对颅底沟通性脑膜瘤侵犯周围骨质的诊断符合率为83.67%(82/98),MRI的诊断符合率为64.29%(63/98),CT高于MRI,组间对比差异有统计学意义(P<0.05)。CT对颅底沟通性脑膜瘤侵犯周围软组织的诊断符合率为66.33%(65/98),MRI的诊断符合率为93.88%(92/98),MRI高于CT,组间对比差异有统计学意义(P<0.05)。结论 CT与MRI均可应用于颅底沟通性脑膜瘤的诊断,在疾病定性诊断中均具有较高的诊断价值;CT的优势是能够清晰地显示颅底孔道、周围骨质增生变化、病灶斑片钙化;MRI的优势是可清晰地显示对周围软组织的侵犯。提示合理应用两种影像学技术,是更准确、更全面地诊断颅底沟通性脑膜瘤的重要方式。

Objective To explore the application value of MRI and CT diagnosis in patients with skull base communicating meningioma.Methods A total of 98 patients with skull base communicating meningioma admitted to Affiliated Hospital of Yan′an University from March 2016 to March 2024 were selected for the study.CT and MRI diagnostic data and clinical data of the patients were reviewed,and the value of CT and MRI in disease diagnosis and tumor invasion of surrounding bone and soft tissue structures was analyzed.Results 98 patients communicated internally and externally at the skull base position,with 62 patients presenting cranio orbital communication,26 patients presenting cranio nasal communication,and 10 patients presenting cranio cervical communication.The accuracy of CT diagnosis in qualitative diagnosis of skull base communicating meningioma reached 85.71%(84/98),while the accuracy of MRI diagnosis in qualitative diagnosis reached 87.76%(86/98).There was no statistically significant difference between the two groups(P>0.05).The diagnostic accuracy rate of CT for skull base communicating meningioma invading surrounding bone was 83.67%(82/98),while the diagnostic accuracy rate of MRI was 64. 29% (63/98). CT was higher than MRI, and the inter group comparison wasstatistically significant (P<0. 05). The diagnostic accuracy of CT for skull base communicating meningiomainvading surrounding soft tissues was 66. 33%( 65/98), while the diagnostic accuracy of MRI was 93. 88%( 92/98).MRI was higher than CT, and the inter group comparison was statistically significant (P<0. 05). Conclusion BothCT and MRI can be used for the diagnosis of skull base communicating meningioma, and have high diagnosticvalue in the qualitative diagnosis of the disease;The advantage of CT is that it can clearly display changes in theskull base foramen, surrounding bone hyperplasia, and lesion calcification;The advantage of MRI is that it clearlydisplays the invasion of surrounding soft tissues. Reasonable application of two imaging techniques is an importantway to diagnose skull base communicating meningiomas more accurately and comprehensively.
