A 42-year-old female was noted to have a mediastinal mass on routine chest roentgenogram. She was asymptomatic and physical examination was unremarkable. Computed tomography of the chest confirmed the presence of a 3.5 cm well circumscribed mass in the middle mediastinum adjacent to the aortic arch. Operation was performed. A solitary middle mediastinal tumor was readily apparent at the aortic arch to the left subclavian artery, originating from the vagus nerve superior to the take-off of the recurrent laryngeal nerve. Excision was possible by enucleation of the mass. The postoperative period was uneventful, although there was paralysis of the left vocal cord as evidenced by hoarseness. Histologically the diagnosis of a schwannoma of the vagus nerve was made.
一名42岁女性在常规胸部X线检查时发现纵隔肿块。她没有症状，体格检查无异常。胸部计算机断层扫描证实，在中纵隔靠近主动脉弓处有一个3.5厘米边界清晰的肿块。进行了手术。在主动脉弓至左锁骨下动脉处很容易看到一个孤立的中纵隔肿瘤，起源于迷走神经，位于喉返神经起始部上方。通过肿块剜除术得以切除。术后过程顺利，不过出现了左侧声带麻痹，表现为声音嘶哑。组织学诊断为迷走神经鞘瘤。
