Cervical schwannoma is a benign peripheral nerve tumor specifically developing from Schwann cells. Cervical sympathetic chain schwannoma is rare. Following a case report, the authors describe its specific radiological and histological characteristics. Treatment is surgical.
A 56-year-old woman consulted for an isolated left lateral cervical mass of several years' standing, but with recently associated pharyngeal discomfort. Cervical CT revealed a vascularized retrostyloid mass with venous-time enhancement, inducing anterior displacement of the jugulo-carotid axis. The tumor could not be identified on fine-needle aspiration cytology, and surgical resection was performed by cervicotomy. Surgical exploration found a tumor developing from the cervical sympathetic nerve, posterior to the jugular vein and carotid sheath. Histopathologic examination diagnosed schwannoma. Postoperative outcome featured Horner's syndrome.
Cervical sympathetic chain schwannoma is a rare benign tumor, to be suspected in the presence of an isolated lateral cervical mass. Preoperative CT is mandatory to guide diagnosis; treatment is surgical, to confirm histologic diagnosis. Postoperative Horner's syndrome often confirms cervical sympathetic chain involvement.
颈交感神经鞘瘤是一种良性周围神经肿瘤，特异性起源于施万细胞。颈交感神经链 schwannoma 很少见。在报告了一例病例后，作者描述了其特定的放射学和组织学特征。治疗方法是手术。
一名 56 岁女性因孤立的左侧颈侧多年肿块就诊，但最近伴有咽部不适。颈椎 CT 显示血管化的寰椎后外侧肿块，静脉期增强，导致颈内-颈动脉轴的前移位。细针抽吸细胞学检查未能识别肿瘤，通过颈切开术进行了手术切除。手术探查发现肿瘤起源于颈交感神经，位于颈内静脉和颈动脉鞘的后面。组织病理学检查诊断为 schwannoma。术后出现霍纳氏综合征。
颈交感神经链 schwannoma 是一种罕见的良性肿瘤，在存在孤立的颈侧肿块时应怀疑。术前 CT 是必要的，以指导诊断；治疗方法是手术，以确认组织学诊断。术后霍纳氏综合征常证实颈交感神经链受累。
