An isolated unilateral hypoglossal nerve lesion is an uncommon cranial nerve palsy. We report a case of isolated hypoglossal nerve paralysis caused by an intra-dural synovial cyst. To our knowledge, this is the first reported case of a twelfth nerve paralysis caused by a synovial cyst. The anatomy of the hypoglossal nerve, its blood supply and the relationship of the nerve to the atlanto-occipital joint are reviewed, along with the common causes of isolated hypoglossal nerve paralysis.
孤立性单侧舌下神经病变是一种罕见的颅神经麻痹。我们报告一例由硬膜内滑膜囊肿引起的孤立性舌下神经麻痹病例。据我们所知,这是首例由滑膜囊肿导致的第十二对脑神经麻痹的报告病例。本文回顾了舌下神经的解剖结构、血液供应以及该神经与寰枕关节的关系,同时也介绍了孤立性舌下神经麻痹的常见病因。
