Schwannomas are rare, benign, slowly growing tumors arising from Schwann cells that line nerve sheaths. Schwannomas arising from the cervical sympathetic chain are extremely rare. Here, we report a case of a 70-year-old man who presented with only an asymptomatic neck mass. Physical examination revealed a left sided Horner syndrome and a neck mass with transmitted pulsation and anterior displacement of the common carotid artery. Computed tomography (CT) showed a well-defined non- enhancing mass with vascular displacement. The nerve of origin of this encapsulated tumor was the sympathetic chain. The tumor was excised completely intact. The pathologic diagnosis was Schwannoma (Antoni type A and Antoni type B). The patient has been well and free of tumor recurrence for 14 months with persistence of asymptomatic left sided Horner syndrome. The clinical, radiological and pathological evaluations, therapy and postoperative complications of this tumor are discussed.
施万细胞瘤是一种罕见的良性肿瘤，生长缓慢，由神经鞘膜的施万细胞产生。起源于颈交感神经链的施万细胞瘤极为罕见。在此，我们报告一例70岁男性患者，其仅表现为无症状的颈部肿块。体格检查发现左侧霍纳综合征以及一个伴有传导性搏动和颈总动脉向前移位的颈部肿块。计算机断层扫描（CT）显示一个边界清晰、无强化的肿块伴有血管移位。这个包膜完整的肿瘤起源神经为交感神经链。肿瘤被完整切除。病理诊断为施万细胞瘤（Antoni A型和Antoni B型）。患者状况良好，在无症状的左侧霍纳综合征持续存在的情况下，14个月无肿瘤复发。本文讨论了该肿瘤的临床、影像学和病理学评估、治疗及术后并发症。
