CT、MRI在眼眶海绵状血管瘤与眼眶神经鞘瘤影像学鉴别诊断中的研究

摘要

目的 对CT、MRI在眼眶海绵状血管瘤与眼眶神经鞘瘤的影像学鉴别诊断中的应用价值进行研究.方法 选取我院2015年3月至2016年3月收治的经CT诊断为眼眶海绵状血管瘤患者38例和眼眶神经鞘瘤患者45例,经MRI诊断为眼眶海绵状血管瘤患者41例和眼眶神经鞘瘤患者39例.对所有患者进行肿瘤鉴别诊断,主要分为定性诊断符合和定位诊断符合,定性诊断符合是影像学诊断与病理诊断结果一致;定位诊断符合是影像学诊断与手术定位结果一致.分别计算CT、MRI的定性、定位诊断符合率.结果 CT诊断的38例眼眶海绵状血管瘤患者定性诊断正确的31例,定性诊断符合率为81.58％;定位诊断正确33例,定位诊断符合率为86.84多.CT诊断的45例眼眶神经鞘瘤患者定性诊断正确的39例,定性诊断符合率为86.67％;定位诊断正确37例,定位诊断符合率82.22％.MRI诊断的41例眼眶海绵状血管瘤患者定性诊断正确的38例,定性诊断符合率为92.68％;定位诊断正确39例,定位诊断符合率为95.12％.MRI诊断的39例眼眶神经鞘瘤患者定性诊断正确的36例,定性诊断符合率为92.31％;定位诊断正确的37例,定位诊断符合率为94.87％.CT、MRI诊断眼眶海绵状血管瘤的定性符合率和定位符合率差异均无统计学意义(P＞0.05),CT、MRI诊断眼眶神经鞘瘤的定性符合率和定位符合率差异也均无统计学意义(P＞0.05).结论 CT、MRI在眼眶海绵状血管瘤和眼眶神经鞘瘤的影像学鉴别诊断中均具有非常重要的作用,二者的定性、定位诊断符合率均很高,具有很高的应用价值.%Objective To study the CT and MRI value in the differential diagnosis of orbital cavernous hemangioma and orbital schwannoma image.Methods in our hospital from March 2015 to March 2016 were diagnosed by CT in 45 cases and 38 cases of orbital schwannoma in patients with orbital cavernous hemangioma,39 cases diagnosed by MRI and 41 cases of orbital schwannoma in patients with orbital cavernous hemangioma.All the patients underwent the differential diagnosis of tumors,mainly divided into qualitative diagnostic and positioning diagnosis and qualitative diagnosis is consistent with the imaging diagnosis and pathological diagnosis;localization diagnosis is the imaging diagnosis and surgical positioning results.Calculation of CT,MRI qualitative,positioning diagnostic compliance rate.Results CT diagnosis of 38 cases of orbital cavernous hemangioma in patients with qualitative diagnosis of 31 cases,the rate of qualitative diagnosis was 81.58％;33 cases were diagnosed correctly,the positioning accuracy of the diagnosis was 86.84％.CT diagnosis of 45 cases of orbital schwannoma were qualitatively correct diagnosis in 39 cases,diagnosis coincidence rate was 86.67％;37 cases were diagnosed correctly positioning,positioning diagnosis rate 82.22％.MRI di agnosis of 41 cases of orbital cavernous hemangioma of the qualitative diagnosis of 38 cases,the rate of qualitative diagnosis was 92.68％;39 cases were diagnosed correctly,the positioning accuracy of the diagnosis was 95.12％.MRI diagnosis of 39 cases of orbital schwannoma were qualitatively correct diagnosis in 36 cases,diagnosis coincidence rate was 92.31％;37 cases of correct diagnosis,diagnosis coincidence rate is 94.87 ％.CT MRI,the qualitative diagnosis of orbital cavernous hemangioma coincidence rate and coincidence rate of localization was no statistically significant difference (P＞0.05),CT MRI,the qualitative diagnosis of orbital neurilemoma coincidence rate and localization coincidence rate differences were not statistically significant(P＞0.05).Conclusion CT and MRI in orbital cavernous hemangioma and orbital neurilemoma were imaging plays a very important role in the differential diagnosis,the coincidence rate is very high,the two qualitative diagnosis,and has high application value.
