MRI对桥小脑角池占位病变的诊断价值分析

目的探讨桥小脑角池内占位病变的MRI影像学表现及诊断价值,为临床提供有效的诊断依据。方法收集我院2010年1月至2014年5月共35例经手术及病理证实桥小脑角池内占位病变,回顾分析患者术前的MRI检查图像。结果 15例为脑膜瘤,占43%;10例为听神经瘤,占29%;5例为表皮样囊肿,占14%;2例为蛛网膜囊肿,2例为皮样囊肿,1例为脂肪瘤,共占14%。结论 MRI影像可清楚地反映桥小脑角池占位病灶的形态、大小、范围等。结合MRI影像学表现可以做出定性诊断,为临床手术治疗提供有效的依据。

Analysis of Diagnostic Value of MRI for Occupied Lesions in Cerebellopontine Angle

Objective To investigate the radiological appearances and diagnostic value of MRI of occupied lesions in cerebellopon-tine angle, and to provide effective diagnostic basis for clinic. Methods 35 cases of patients with cerebellopontine angle proved surgically and pathologically in our hospital from January 2010 to May 2014 were selected, the preoperative MRI of these patients were retrospectively investigated. Results 15 cases were meningeoma, accounting for 43%;10 cases were acoustic neuroma, accounting for 29%;5 cases were epidermoid cyst, accounting for 14%;2 cases were arachroid cyst, 2 cases were dermoid cyst and 1 case was lipoma, which totally accounted for 14%. Conclusions As MRI can clearly reflect the shape, size and scope of the occupied lesions in cerebellopontine angle, we can make a qualitative diagnosis combining with MRI, thus to provide effective basis for clinical surgery.
