作者报道1例垂体瘤表现为三叉神经眼支痛12年的患者,除了这类表现罕见外,最显著方面是其神经痛发作能因口服量溴隐亭激发,因而有机会研究人垂体瘤溴隐亭的体内急性作用。病例男性,51岁,10年前右三叉神经眼支分布区阵发性重度射痛发作,每次历时30～60sec,屈身和咳嗽可激发之,不能定位板机区,频率由1h到1月发作1次,服卡马西平无效。体检包括眼活动、视敏度、视野、眼底镜检、角膜反射和面感觉试验均未见异常。CT、X线断层照相、磁共振成象发现有鞍上和右侧伸展垂体瘤,颈动脉造影正常。刺激右眶上神经,左顶压无引起的电位(SSEP)可识别,而刺激健侧则有正常的应答。开始用溴隐亭治疗,口服首次量1.25mg后2小时,右眼神经分布区有一连串反复剧
The authors report that in 1 patient with pituitary adenocarcinoma showing tributary eye pain for 12 years, in addition to the rare occurrence of this type of manifestations, the most striking aspect of this is that the onset of neuralgia can be stimulated by oral doses of bromocriptine, giving the opportunity to study human pituitary tumor bromine bromine Cisterns in vivo acute effect. Cases of male, 51 years old, 10 years ago, the distribution of right trigeminal nerve branch of paroxysmal severe pain episode, each time lasted 30 ~ 60sec, flexion and cough can be stimulated, can not locate the board machine frequency from 1h to January Attack 1, serving carbamazepine invalid. Physical examination including ocular activity, visual acuity, visual field, funduscopy, corneal reflex and facial sensory test were normal. CT, X-ray tomography, magnetic resonance imaging found in the suprasellar and right extensor pituitary tumor, carotid artery angiography normal. Stimulation of the right supraorbital nerve, left unpressurized potential (SSEP) can be identified, while stimulating the contralateral side there is a normal response. Begin with bromocriptine treatment, oral first 1.25mg 2 hours after the right eye nerve distribution area has a series of repeated drama
