We report a case of foramen magnum meningioma manifesting as hypoglossal nerve palsy. A 72-year-old woman presented with progressive hypoglossal nerve palsy and lingual atrophy on the left side. Gadolinium-enhanced T1-weighted magnetic resonance imaging revealed a heterogeneously enhanced mass lesion with dural tail sign partially extending into the hypoglossal canal. The transcondylar approach was performed to expose the hypoglossal canal and resect the tumor completely. Histological examination revealed a transitional meningioma. The postoperative course was uneventful. Hypoglossal nerve palsy improved gradually after the operation.
我们报告一例以舌下神经麻痹为表现的枕骨大孔脑膜瘤。一名72岁女性出现进行性舌下神经麻痹及左侧舌肌萎缩。钆增强T1加权磁共振成像显示一个不均匀强化的肿块病变，伴有硬膜尾征，部分延伸至舌下神经管。采用经髁入路暴露舌下神经管并完整切除肿瘤。组织学检查显示为过渡型脑膜瘤。术后过程顺利。术后舌下神经麻痹逐渐改善。
