Gasser氏神经节纤维瘤即三叉神经半月节神经纤维瘤,约占颅内神经纤维瘤的2.5％,但尸检发现为7.5％,说明本病早期与颅底的原发性肿瘤鉴别诊断是困难的。为了提高临床对本病之认识,本文作者对经手术或尸解证明为本病的30例进行讨论。男6例、女24例,年龄为19—54岁,该病首发症状常以头部钝痛和面部或半面部麻木感或具有三叉神经痛发作之特征,常迅速合并运动方面的损害,表现为咀嚼肌无力或萎缩;此外,角膜反射减弱或消失。 Gasser ganglioniferous fibroids are trigeminal half-moon neurofibromas, accounting for about 2.5% of intracranial neurofibromas, but autopsy found 7.5%, indicating that the early diagnosis of this disease and the skull base of the primary tumor is difficult to differential diagnosis . In order to improve the clinical understanding of the disease, the authors discussed 30 cases that proved to be the disease by surgery or autopsy. There were 6 males and 24 females, aged 19-54 years. The first symptom of the disease was characterized by dull head pain and numbness on facial or semi-facial or trigeminal neuralgia. It was often combined with rapid motor impairment. For the masticatory muscle weakness or atrophy; In addition, the corneal reflex weakened or disappeared.
