摘要
目的:探讨不典型脑膜瘤MRI表现,分析误诊原因,以提高不典型脑膜瘤MRI诊断准确率。方法:回顾性分析12例经病理证实的脑膜瘤病例,术前MRI均未将脑膜瘤列为第一诊断。所有病例均行MR平扫加增强扫描。结果:12例患者中,7例位于典型部位,5例位于不典型部位。其中9例第二或第三诊断为脑膜瘤,3例未诊断脑膜瘤。结论:不典型脑膜瘤MRI影像表现多样,缺乏典型征象,提高对其影像表现的认识可减少误诊。
Objective ： To investigate the MRI features of atypical meningioma, to analyze the reasons of misdiagnosis and improve the accuracy rate of MRI in diagnosis of atypical meningioma.Method： 12 cases with pathologically confirmed meningioma were analyzed retrospectively, which were not listed as the first diagnosis in preoperative MRI.All cases underwent MR plain scan and enhanced scan.Result： In 12 cases there were 7 cases in the typical sites, 5 cases in atypical sites; 9 cases with second or third diagnosis ofmeningioma, 3 cases without diagnosis ofmeningioma.Conclusion： Atypical meningioma has various MRI imaging manifestations without typical signs.Improving the understanding of its image manifestations can reduce misdiagnosis.
