颈部迷走神经副神经节瘤1例报告并文献复习

Cervical Vagal Paraganglioma: A Case Report and Literature Review

目的探讨颈部迷走神经副神经节瘤的临床病理、影像学特征及治疗方法。方法回顾性分析1例颈部迷走神经副神经节瘤患者的临床资料,并结合相关文献复习。患者女性,59岁,左上颈部肿块约4. 5 cm×4. 0 cm×4. 0 cm大小,行手术治疗,术中充分显露肿瘤后见肿瘤血供丰富,切断肿瘤供血血管,探查并发现肿瘤与迷走神经关系密切,予以保留部分迷走神经并将肿瘤切除。结果术后病理证实为副神经节瘤,术后出现轻微声音嘶哑及进食呛咳。复习相关文献及总结本病例特点,提示迷走神经副神经节瘤有其特定的发病部位和MRI特征,治疗以手术为主。结论迷走神经副节瘤临床表现无特异性,术前诊断较为困难,可依据临床症状的严重程度选择手术或放疗,预后较好。

Objective To explore the clinical pathological, imaging features indications and treatment of cervical vagal paraganglioma（VP）. Methods The clinical data of one patient with cervical VP was retrospectively analyzed. And the associated literatures were reviewed. The patient was female, aged 59, and was found the tumor located in upper left neck with size of 4.5 cm×4.0 cm×4.0 cm. The surgical intervention was performed. After fully exposing the tumor during the operation, the tumor blood supply showed abundantly, and the blood vessel was cut off. The tumor was closely related to the vagus nerve, so the partial vagus nerve was retained and the tumor was removed. Results Postoperative pathology confirmed the VP in the case. The mild postoperative hoarseness and eating choke to cough appeared after the surgery. Reviewed the relevant literatures and summarize the characteristics of the case, it is suggested that VP has its specific location and MRI features, and surgical treatment is the most important. Conclusions The clinical manifestation of the VP is nonspecific and difficult to be diagnosed before operation. The surgery or radiotherapy can be selected according to the severity of clinical symptoms, and the prognosis is reliable.
