There are no reported cases of hemifacial spasm associated with an arachnoid cyst in the literature. We report the first case of hemifacial spasm with an ipsilateral cerebellopontine angle arachnoid cyst in a 25-year-old man. The patient underwent evacuation of the arachnoid cyst by a partial membranectomy without any beneficial effect, and finally got rid of the hemifacial spasm by reexploration and microvascular decompression of the facial nerve. The operative findings and results revealed that the cyst produced deviation of the ipsilateral posterior inferior cerebellar artery, which was secondarily in contact with the root exit zone of the facial nerve.
文献中尚无与蛛网膜囊肿相关的半面痉挛病例报道。我们报告首例25岁男性患有同侧桥小脑角蛛网膜囊肿伴发半面痉挛的病例。该患者接受了部分囊壁切除术以排空蛛网膜囊肿，但未取得任何有益效果，最终通过再次探查及面神经微血管减压术摆脱了半面痉挛。手术所见及结果显示，囊肿致使同侧小脑后下动脉移位，继而与面神经根部出口区接触。
