摘　　要：目的:探讨神经纤维瘤病的CT和MRI影像表现,并就二者的优劣进行比较。方法:分析17例神经纤维瘤病的临床特点和CT、MRI表现,并就NFⅠ型与其它神经皮肤综合症、NFⅡ型与常见发生于桥小脑角区的肿瘤进行了鉴别。结果:17例神经纤维瘤病中,NFⅠ型6例,NFⅡ型11例。CT显示NF不及MRI,后者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,优于CT。Objective：To study the CT and MRI features of neurofibromatosis（NF）, with their advantage and defect were compared. Methods： This study included 17 patients of neurofibromatosis, the clinic features, CT and MRI findings were analyzed retrospectively. NF type I with other neurocutaneous syndrome, NF type Ⅱ with usual cerebellopontine angle tumors were compared. Results： Neurofibromatosis was found in NF Ⅰ （n = 6） and NFⅡ （n = 11 ）, MRI could well demonstrate the distribution, the size, the shape and the signal characteristics of neurofibromatosis. Conchsion：MRI can be considered as first choice of study in diagnosing of neurofibromatosis, it is superior to CT.
