【摘要】 目的:分析桥小脑角区肿瘤的MRI表现,以提高桥小脑角区肿瘤术前诊断的准确率.方法:收集一组经手术及病理证实的桥小脑角区肿瘤120例,全部病例行MRI平扫加增强检查.结果:本组120例中,其中听神经瘤45例、脑膜瘤37例、三叉神经瘤6例、表皮样囊肿8例、蛛网膜囊肿7例、胶质瘤6例、血管网状细胞瘤6例、海绵状血管瘤5例.肿瘤位于左侧桥小脑角区占64例,位于右侧桥小脑角区占59例.术前定位准确率为100%,定性准确率达97.5%.结论:MRI在桥小脑角区肿瘤的诊断与鉴别诊断中具有较高价值,可作为桥小脑角区肿瘤的术前首选检查方法.更多还原

【Abstract】 Objective: To improve the preoperative diagnosis accuracy of cerebellopontine angle tumors through analyzing MRI findings.Methods: Collecting 120 cases of cerebellopontine angle tumors which confirmed by pathology and surgery,all cases underwent MRI scan plus enhanced MRI.Results: In 120 cases,acoustic neuroma in 45 cases,meningioma in 37 cases,6 cases of trigeminal neuroma,epidermoid cyst in 8 cases,arachnoid cyst in 7 cases,glioma in 6 cases,6 cases of angioreticuloma,cavernous angioma in 5 cases.Tumors located in the left cerebellopontine angle accounted for 64 cases,located on the right cerebellopontine angle accounted for 59 cases.Preoperative localization accuracy was 100%,qualification accuracy rate was 97.5%.Conclusion: MRI has a high value in the diagnosis and differential diagnosis of cerebellopontine angle tumors,which can be used as a preferred preoperative examination method in cerebellopontine angle tumors.更多还原
