Schwannomas are benign tumors originating from Schwann cells of the myelin sheath. The cystic appearance of a cervical vagal schwannoma is an extremely rare finding, with few patients reported in the literature. A 60-year-old female patient was seen at our service for a slow-growing, 9 × 6 cm left-sided cystic neck mass. Preoperative clinical and computed tomography evaluation suggested a diagnosis of a lateral neck cyst. The surgical exploration through the lateral cervicotomy revealed a large cystic mass and clearly identified that the tumor was originating from the left vagal nerve. The histopathologic analysis confirmed the diagnosis of schwannoma. Although uncommon, vagal schwannoma with pronounced cystic component should be included in the differential diagnosis of the cystic neck swellings.
施万细胞瘤是起源于髓鞘施万细胞的良性肿瘤。颈迷走神经施万细胞瘤呈囊性表现极为罕见，文献报道的病例很少。一名60岁女性患者因左侧颈部缓慢生长的9×6 cm囊性肿块前来我院就诊。术前临床及计算机断层扫描评估提示诊断为侧颈部囊肿。通过颈部侧方切口进行手术探查，发现一个大的囊性肿块，并明确肿瘤起源于左侧迷走神经。组织病理学分析证实为施万细胞瘤。尽管不常见，但具有明显囊性成分的迷走神经施万细胞瘤应列入颈部囊性肿物的鉴别诊断。
