【摘要】 目的 探讨神经纤维瘤病的MRI影像特征。方法 分析15例神经纤维瘤病的临床特点和MRI表现，并就NF Ⅰ型与其他神经皮肤综合征、NF Ⅱ型与常见发生于桥小脑角区的肿瘤进行了鉴别。结果 15例神经纤维瘤病中，NF Ⅰ型5例，NF Ⅱ型10例。MRI能够全面准确地显示病灶分布，病变大小、形态和信号特征以及与相邻组织结构的关系，特别是MR增强扫描能够显现伴发的颅内小病灶。结论 MRI是目前诊断神经纤维瘤病的最佳影像学检查方法。

    【Abstract】 Objective To study the MRI features of neurofibromatosis.Methods This study included 15 patients of neurofibromatosis(NF),the clinic features and MRI findings were analyzed.NF type Ⅰ from other neurocutaneous syndrome and NF type Ⅱ from usual cerebellopontine angle tumors were differentiated.Results Neurofibromatosis was found in NF Ⅰ(n=5)and NF Ⅱ(n=10).MRI could well demonstrate the locations,the sizes,the shapes and the signal attributes of neurofibromatosis.Conclusion MRI can be considered as the first choice of study in diagnosing of neurofibromatosis. ......
