Imaging Findings of Gastric Neurogenic Tumors and Literature Review

目的:探讨胃神经源性肿瘤的临床及影像学特征。材料和方法:对胃镜及手术后病理学确诊的2例胃神经源性肿瘤的影像学表现进行回顾性分析,并复习相关临床及影像学文献。结果:胃神经源性肿瘤多表现为圆形、类圆形突出于胃腔内外的软组织肿块,密度多稍低,形态多较规则,其胃腔侧可形成溃疡,增强扫描为缓慢持续性较均匀中等程度强化,周围可出现反应性淋巴结增大。结论:胃道神经源性肿瘤影像学表现有一定特征,若CT扫描发现有上述表现时,要考虑到胃神经源性肿瘤可能,以减少误诊,确诊多需病理学及免疫组化检查。

Objictive:To investigate the clinical and imaging features of gastric neurogenic tumors.Materials and Methods:To retrospective analysis the imaging features of two cases of gastric neurogenic tumor confirmed by gastroscope and pathology after operation,and review the relevant clinical and imaging literature. Results:Gastric neurogenic tumors are mostly show as round or quasi-circular soft tissue masses that protruding from the inside and outside of the gastric cavity, with slightly lower density and more regular shape. Ulcerations can be formed on the side of the gastric cavity, and the enhancement scan results in slow and continuous relatively uniform and moderate degree of enhancement, and reactive lymph node enlargement may occur in the periphery. Conclusion:The imaging findings of gastric neurogenic tumors have certain characteristics. If CT scan found that the performance, may want to consider the gastric neurogenic tumor, in order to reduce the misdiagnosis. Confirm the diagnosis are often needed to pathology and immunohistochemical examination.
