A 49 year-old man with trigeminal neuralgia caused by megadolichobasilar anomaly was described. The patient having neuralgic attacks in the second branch of the right trigeminal nerve for two and a half years showed the angiographic evidence of a tortuous and elongated vertebrobasilar artery and MRI of the brain clearly visualized the root entry zone of the nerve having been compressed by the main trunk of ectatic basilar artery. Cases of trigeminal neuralgia due to the compression by the basilar artery itself have been rarely described previously. In order to evaluate trigeminal neuralgia, MRI is essential to determine the relationship of the involved site of nerve to the pathogenic artery.
本文描述了一名49岁因巨长基底动脉异常导致三叉神经痛的男性患者。该患者右侧三叉神经第二支出现神经痛发作已两年半，血管造影显示椎基底动脉迂曲延长，脑部MRI清晰显示扩张的基底动脉主干压迫神经的神经根入区。以往很少有关于基底动脉本身压迫导致三叉神经痛的病例报道。为评估三叉神经痛，MRI对于确定神经受累部位与致病动脉的关系至关重要。
