摘　　要：目的评估常规MRI听神经瘤术前诊断及其临床应用价值。方法回顾性分析87例资料完整经手术、病理证实的听神经瘤MRI资料,与手术所见、病理结果对照,观察、评价常规MRI检查对听神经瘤的术前诊断、分级、分期及肿瘤与对邻近脑干、小脑、周围神经压迫的结构关系及影响情况。结果 87例听神经瘤术前MRI诊断与手术病理符合率达100%。术前分级、分期、分型准确,与手术所见基本相符。常规MR显示肿瘤与脑干、同侧小脑半球及第四脑室推压情况与手术所见一致,但显示肿瘤与邻近周围颅神经、小血管关系差。结论常规MRI术前诊断术前评估听神经瘤准确,但对颅神经、小血管评估不足。Objective To evaluate the clinical application of conventional MRI in preoperative assessment of auditory neuroma. Methods The MRI findings of 87 patients with acoustic neuroma confirmed by surgery and pathology were analyzed retrospectively. Comparing with the findings on operation and pathology,we evaluated the preoperative assessment,grading and staging of MRI on auditory neuroma,as well as the structural relationship between tumor and brainstem,cerebellum and adjacent nerves. Results The coincidence rate between MRI diagnosis and pathology of 87 cases was 100%. The preoperative grading and surgical staging were consistent with the findings on operation. Conventional MRI could show the relationship between the tumor and brainstem,homolateral cerebellar hemisphere and the fourth ventricle clearly,which were consistent with surgical findings. But it could not show the relationship between the tumor and the adjacent cranial nerves and small vessels. Conclusion The preoperative diagnosis of conventional MRI in acoustic neuroma is accurate,but the evaluations of cranial nerves and small vessels are insufficient.
