神经纤维瘤病(neurofibromatosis,NF)分为I、I两型

 

 

神经纤维瘤病(neurofibromatosis,NF)分为I、I两型


NF-I型又名von Recklinghausen病,占90%,NF-II型也称为中枢型神经纤维瘤病或双侧听神经瘤病,可并发其他中枢神经系统肿瘤

 

 

 

I、I型发生病变的部分和性质有所不同,但均为常染色体显性遗传性疾病


NF-I型临床诊断标准(美国国家卫生研究会,NIH)
符合下列2条及以上可诊断NF-I型


1)皮肤牛奶咖啡斑(≥6个,青春期前>0. 5cm,青春期后>1. 5cm) ;
2)任何类型神经纤维瘤(≥2个)或丛状神经纤维瘤(1个);
3)腋窝或腹股沟区雀斑;
4)视神经或其他脑实质胶质瘤;
5)Lisch结节:虹膜黑色素细胞错构瘤(≥2个);
6)特征性骨病变:蝶骨大翼发育不良/缺损,假关节或长骨骨皮质变薄等;
7)直系一级亲属NF-I型家族史

 


NF-II型临床诊断标准(美国国家卫生研究会,NIH)符合下列任何1种异常可诊断NF-II型
1)CT或MRI显示双侧听神经瘤;
2)家族史伴单侧听神经瘤或任何2个病变:神经纤维瘤;脑膜瘤;胶质瘤;神经鞘瘤;青少年晶状体后包膜下混浊;
3)缺乏双侧前庭神经鞘瘤或NFII型家族史,但被诊断为多发神经鞘瘤和/或脑膜瘤的患者,室管膜瘤提高阳性预测值
