摘　　要：目的分析桥小脑角区肿瘤应用MRI诊断鉴别的价值.方法以2014年3月至2017年3月本院接诊且经手术病理证实的70例桥小脑角区肿瘤患者为研究对象,所有入选患者都接受MRI检查,综合分析70例患者的MRI影像学表现.结果70例患者中,脑膜瘤16例,表皮样嚢肿11例,血管母细胞瘤1例,听神经瘤28例,蛛网膜嚢肿7例,淋巴瘤2例,三叉神经瘤5例.术前定位诊断准确率为98.57%,定性诊断准确率为97.14%.结论桥小脑角区肿瘤的MRI影像学表现具有特征性,利用MRI进行诊断,可提高临床诊断的准确性.Objective To analyze the value of MRI in the differential diagnosis of cerebellopontine angle tumor. Methods Seventy cases of patients who confirmed as cerebellopontine angle tumor by surgery and pathology in our hospital from March 2014 to March 2017 were selected as the study objects. All the patients accepted MRI detection, and the MRI imaging findings were analyzed. Results In 70 cerebellopontine angle tumor, there were 16 cases with meningioma, 11 cases with epidermoid cyst, 1 case with hemangioblastoma, 28 cases with acoustic neuroma, 7 cases with intracranial arachnoid cyst, 2 cases with lymphoma and 5 cases with trigeminal neuroma. The preoperative localization diagnostic accuracy was 98.57%, and the qualitative diagnostic accuracy was 97.14%. Conclusion For cerebellopontine angle tumor, the MRI imaging has characteristic findings. Using MRI in the diagnosis of cerebellopontine angle tumor can improve the accuracy rate of clinical diagnosis.
