Neurofibromas originating from vagus nerves are rarely reported in the literature. In particular, plexiform neurofibromas of the bilateral cervical vagus nerve are extremely rare.
A 21-year-old female presented with a 2-year history of swelling on the right side of her neck. Physical examination revealed a soft-tissue mass on the right side of her neck. Ultrasonography (US) and magnetic resonance (MR) imaging showed a tumor centered in the right carotid sheath between the internal jugular vein and the common carotid artery. In addition, a similar nodular mass in the left carotid sheath was detected on US. The right mass was surgically resected; histopathological examination revealed a neurofibroma.
US can be a valuable method for preoperative evaluation of cervical mass, as it is capable of displaying the vagus nerve and provides sufficient diagnostic information. The cervical vagal neurofibroma can manifest as solitary or multifocal lesion. Bilateral neurofibromas are usually associated with neurofibromatosis type 1 (NF1). Early diagnosis and prompt surgical treatment should be considered.
文献中很少报道起源于迷走神经的神经纤维瘤。特别是双侧颈迷走神经的丛状神经纤维瘤极为罕见。
一名21岁女性，有右侧颈部肿胀2年病史。体格检查发现右侧颈部有一软组织肿块。超声（US）和磁共振（MR）成像显示肿瘤位于右侧颈动脉鞘内，在颈内静脉和颈总动脉之间。此外，超声检查发现左侧颈动脉鞘内有一类似结节状肿块。右侧肿块经手术切除；组织病理学检查显示为神经纤维瘤。
超声可作为颈部肿块术前评估的一种有价值的方法，因为它能够显示迷走神经并提供足够的诊断信息。颈迷走神经纤维瘤可表现为孤立性或多灶性病变。双侧神经纤维瘤通常与1型神经纤维瘤病（NF1）相关。应考虑早期诊断和及时手术治疗。
