The authors report a rare case of right cerebellopontine angle cyst related to hemifacial spasm. The patient was a 66-year-old woman with a 3-year history of right hemifacial spasm. The cyst was diagnosed preoperatively by T2-weighted magnetic resonance imaging, which demonstrated a hyperintense area in the right cerebellopontine angle. A small artery was displaced by the cyst and compressed the root exit zone of the facial nerve. Decompression of the cyst and the vasculature using a microsurgical technique resulted in total recovery from hemifacial spasm.
作者报告了一例罕见的与半面痉挛相关的右侧桥小脑角囊肿病例。患者为一名66岁女性,有3年右侧半面痉挛病史。术前通过T2加权磁共振成像诊断出囊肿,该成像显示右侧桥小脑角有一个高信号区。一条小动脉被囊肿移位并压迫面神经的根出区。采用显微外科技术对囊肿和血管进行减压后,患者的半面痉挛完全康复。
