We report a case of primary extracranial meningioma arising from the hypoglossal nerve in a 54-year-old man who presented with a 9-month history of hoarseness and progressive dysphagia. He had also noticed that his tongue was deviated to the left and, as a result, he was having difficulty pronouncing words. Examination revealed fasciculation and muscle wasting on the left side of the tongue. Other cranial nerve functions were normal. Contrast-enhanced computed tomography detected a heterogeneous mass that had arisen above the bifurcation of the left common carotid artery and had extended to near the skull base. Transcervical excision of the tumor was performed, and histopathology identified it as a meningioma of the hypoglossal nerve. The patient recovered uneventfully, and he was without recurrence at more than 2 years of follow-up. A primary extracranial meningioma is extremely rare, and its presentation may be subtle. A thorough investigation is necessary to avoid fatal compressive symptoms.
我们报告一例54岁男性原发性颅外脑膜瘤，起源于舌下神经，患者有9个月的声音嘶哑和进行性吞咽困难病史。他还注意到自己的舌头向左偏斜，因此说话困难。检查发现左侧舌部有肌束震颤和肌肉萎缩。其他颅神经功能正常。增强计算机断层扫描检测到一个异质性肿块，位于左颈总动脉分叉上方，并延伸至颅底附近。对肿瘤进行了经颈切除术，组织病理学检查确定为舌下神经脑膜瘤。患者恢复顺利，随访2年多无复发。原发性颅外脑膜瘤极为罕见，其表现可能不明显。需要进行全面检查以避免致命的压迫症状。
