摘　　要：目的:通过回顾性分析胃神经鞘瘤的临床特征及影像学表现,提高对胃神经鞘瘤的认识。方法:收集2010年1月~2019年12月本院病理确诊的胃神经鞘瘤病例共4例,对临床资料及临床症状、影像特征等进行整理分析,并结合相关文献学习讨论。结果:4例胃神经鞘瘤,3例因上腹部不适就诊,1例为体检发现;3例位于胃体,1例位于近贲门处;3例直径<3cm,1例直径>6cm;肿瘤均为单发,大多为圆形,部分伴分叶,其中2例伴有溃疡,CT及MRI多期扫描呈渐进性强化,体积较大者密度/信号、强化不均匀。免疫组化特征为CD34(-)、CD117(-)、S-100(+)。结论:胃神经鞘瘤的临床症状无特异性,影像学上多为圆形,密度或信号均匀,渐进性强化的特征有助于鉴别诊断,最终的确诊还需依赖病理及免疫组织化学检查。Objective:Through retrospective analysis of the clinical characteristics and imaging manifestations of gastric schwannoma(GS)in our hospital,and learning related literature,to improve the understanding of GS.Methods:A total of 4 cases of GS confirmed by pathology in our hospital from January 2010 to December 2019 were collected.Clinical data,symptoms and imaging features were analyzed,and related literature was studied and discussed.Results:Of 4 cases of GS,3 appeared upper abdominal discomfort,1 was found by physical examination.3 patients were located in the gastric body,and 1 was located near the cardia.3 cases were measured less than 3cm,and one more than 6cm.The tumors were all single,mostly round,with partial lobules,and 2 of them were accompanied by ulcers.The CT and MRI multi-phase scanning were all characterized by progressive enhancement,and the larger one showed uneven density/signal and enhancement.Immunohistochemical characteristics were CD34(-),CD117(-)and S-100(+).Conclusion:The clinical symptoms of GS are not specific.The imaging features of GS are mostly round,uniform in density or signal.Progressive enhancement is helpful for differential diagnosis.
