Abstract：
Trigeminal neuralgia (TN) is a disabling painful condition along the course of the sensory distribution of the trigeminal nerve that most commonly occurs due to vascular compression or conflict at the root entry zone of the trigeminal nerve. We report a 27-year-old female patient who presented with pain and an electric shock-like sensation on the right side of her face that started three years ago. Magnetic resonance imaging of the brain was done and revealed no neurovascular conflict along the course of the trigeminal nerve. The absence of Meckel\'s cave with atrophy of the cisternal segment of the trigeminal nerve on the affected side was reported. The absence of Meckel\'s cave is an exceedingly rare cause of TN, and only a handful of reported cases in the literature suggest the association between them.
摘要：
三叉神经痛（TN）是三叉神经感觉分布过程中的致残疼痛状况，最常见于三叉神经根部进入区的血管压迫或冲突。我们报告了一名27岁的女性患者，三年前开始，她的脸右侧出现疼痛和类似电击的感觉。进行了大脑的磁共振成像，发现沿三叉神经的过程中没有神经血管冲突。据报道，在患侧没有Meckel的洞穴，三叉神经的脑池段萎缩。Meckel\'s洞穴的缺失是导致TN的极为罕见的原因,文献中只有少数报道的病例表明它们之间存在关联。
