The authors report a case of neurofibromatosis Type 2 presenting with symptoms of trigeminal neuralgia refractory to medical management following placement of an auditory brainstem implant (ABI). Physical examination and history revealed trigeminal neuralgia. A 3D FIESTA (fast imaging employing steady-state acquisition) MR imaging study demonstrated compression of the trigeminal nerve by an ABI cable. After maximal medical therapy, a retrosigmoid microscopic decompression of the trigeminal nerve achieved complete symptom resolution. This is the first report of an ABI cable becoming displaced, resulting in neurovascular compression. This case demonstrates that trigeminal neuralgia can result from nonvascular compression of the trigeminal nerve.
作者报告了一例神经纤维瘤病 2 型病例，该患者在植入听觉脑干植入物（ABI）后出现三叉神经痛症状，且对药物治疗无反应。体格检查和病史显示为三叉神经痛。3D FIESTA（稳态采集快速成像）磁共振成像研究显示 ABI 电缆压迫三叉神经。在最大程度的药物治疗后，经乙状窦后显微减压术完全缓解了三叉神经痛症状。这是首例 ABI 电缆移位导致神经血管压迫的报告。该病例表明，三叉神经痛可由三叉神经的非血管压迫引起。
