We describe an unusual and rare case of isolated left hypoglossal nerve palsy secondary to compression from a prominent degenerative osteophyte from the left atlanto-occipital joint. The hypoglossal nerve is a purely motor cranial nerve innervating the tongue musculature. Palsy of the hypoglossal nerve is frequently associated with other cranial nerve palsies and can be related to vascular, neoplastic, infectious or traumatic conditions. Isolated hypoglossal nerve palsy is quite rare and very few cases have been reported in the literature to date.
我们描述了一例罕见的孤立性左侧舌下神经麻痹病例，其继发于来自左寰枕关节处一个明显的退行性骨赘的压迫。舌下神经是一条纯粹的运动性颅神经，支配舌肌。舌下神经麻痹常与其他颅神经麻痹相关，且可能与血管性、肿瘤性、感染性或创伤性疾病有关。孤立性舌下神经麻痹相当罕见，迄今为止文献中报道的病例极少。
