Abstract

Hypoglossal nerve (HyN) schwannomas are uncommon tumors. The leading symptoms are unilateral tongue weakness and atrophy. The neoplasms are diagnosed by MRI imaging. The surgical treatment of hypoglossal schwannomas (HS) is challenging because the tumor is closely related to brainstem structures, cranial nerves, and arteries of the vertebrobasilar system. Their removal is associated with a high risk of patient disability. This report presents a clinical case study of a 68-year-old patient with an unusual clinical presentation of intradural HS. There were no signs of tongue weakness or atrophy observed in the patient. After the tumor was diagnosed, it was radically removed. This case highlights the importance of early detection and complete microsurgical resection of schwannoma to prevent neurological deficits and ensure a favorable postoperative outcome, thus maintaining the patient's quality of life. Keywords: Hypoglossal nerve, schwannoma, tongue weakness and atrophy, microsurgery.

无舌下麻痹及舌萎缩之硬膜内舌下神经鞘瘤一例及文献回顾

舌下神经鞘瘤是一种少见的肿瘤。主要症状是单侧舌头无力和萎缩。肿瘤通过核磁共振成像诊断。舌下神经鞘瘤(HS)的手术治疗具有挑战性，因为肿瘤与脑干结构、颅神经和椎基底系统动脉密切相关。切除它们与患者残疾的高风险相关。本报告提出了一个临床病例研究的68岁患者的临床表现不寻常的硬膜内HS。患者未见舌头无力或萎缩的迹象。肿瘤确诊后，就被彻底切除了。本病例强调了神经鞘瘤的早期发现和完全显微手术切除对于预防神经功能缺损和确保良好的术后预后，从而维持患者的生活质量的重要性。关键词:舌下神经，神经鞘瘤，舌无力萎缩，显微外科。
