【摘要】：目的 :探讨用MRI检查对桥小脑角区脑膜瘤和听神经瘤进行鉴别诊断的临床效果。方法 :对2012年8月~2016年6月期间我院收治的45例桥小脑角区脑膜瘤及听神经瘤患者的临床资料进行回顾性研究。对这45例患者均进行MRI平扫+增强扫描检查,并对其进行手术治疗。然后,将手术病理检查的结果作为最终的诊断结果,观察用MRI检查对这两种肿瘤患者进行鉴别诊断的准确性,并比较这两种肿瘤患者MRI图像的特点。结果:进行手术病理诊断的结果为:在这45例患者中,有29例患者患有听神经瘤,有16例患者患有脑膜瘤。对这45例患者使用MRI检查进行鉴别诊断的结果与其进行手术病理诊断的结果相符。这两种肿瘤患者肿瘤的位置、形状和大小相比差异均无统计学意义(P0.05)。这两种肿瘤患者的T1WI信号和T2WI信号相比差异均具有统计学意义(P0.05)。这两种肿瘤患者肿瘤处的囊变、出血、瘤周水肿、以内听道为中心、累及听神经、听神经增粗等图像表现相比差异均具有统计学意义(P0.05)。结论 :用MRI检查对桥小脑角区脑膜瘤和听神经瘤进行鉴别诊断的效果显著。
[Abstract]:Objective: to investigate the clinical effect of MRI in differential diagnosis of meningioma and acoustic neuroma in cerebellopontine angle. Methods: the clinical data of 45 patients with meningioma and acoustic neuroma in cerebellopontine angle from August 2012 to June 2016 were retrospectively studied. All the 45 patients were examined by MRI plain contrast-enhanced scan and treated surgically. Then, using the results of surgical and pathological examination as the final diagnosis result, the accuracy of differential diagnosis between the two kinds of tumor patients was observed by MRI, and the characteristics of MRI images of the two kinds of tumor patients were compared. Results: of the 45 patients, 29 had acoustic neuroma and 16 had meningioma. The results of differential diagnosis with MRI in 45 patients were consistent with the results of surgical and pathological diagnosis. There was no significant difference in tumor location, shape and size between the two groups (P0.05). The difference of T1WI signal and T2WI signal between the two kinds of tumor patients was statistically significant (P0.05). There were significant differences between the two kinds of tumors in terms of cystic change, hemorrhage, peritumor edema, inner auditory canal center, involvement of acoustic nerve and enlargement of auditory nerve (P0.05). Conclusion: MRI is effective in differential diagnosis of cerebellopontine angle meningioma and acoustic neuroma.
