摘　　要：目的探讨CT检查对胃部间叶组织来源肿瘤的诊断价值。方法回顾性分析92例经手术病理证实的胃部间叶源性肿瘤的CT表现。结果 92例胃部间叶源性肿瘤中,间质瘤47例,淋巴瘤39例,平滑肌瘤2例,神经纤维瘤2例,脂肪瘤1例,血管球瘤1例。病变部位:胃底26例,胃体57例,胃窦36例;生长方式:腔内肿块20例,腔外肿块27例,跨壁生长型肿块7例,胃壁弥漫增厚型38例。1例脂肪瘤以脂肪密度为主;8例间质瘤可见粗大的颗粒状钙化,间质瘤及神经纤维瘤各1例可见蛋壳状钙化;CT增强病例中,增厚的胃壁强化不均匀;1例血管球瘤肿块明显均匀强化;余增强病例呈轻、中度强化。结论 CT检查对胃间叶源性肿瘤的诊断有很大的价值。Objective To investigate the value of image with CT in the diagnosis of gastric mesenchymal tumors. Methods The CT imaging appearances of 92 cases of gastric mesenchymal tumors proved by operation and pathology were reviewed retrospectively. Results In 92 cases, there were 47gastrointestinal stromal tumors, 39 lymphomas, 2 leiomyomas, 1 neurofibroma, llipoma and lglomus tumor. Lesions： 26 cases of gastric fundus, 57 cases of gastric body, 36 cases of gastric antrum; Growth pattern： intraluminal mass for 20 cases, external gastric for 27 cases, cross-wall growth type tumors for 7 cases,and diffuse gastric wall thickening in 38 cases. 1 case of lipoma with fat density ; 8 cases of stromal tumors with granular calcification, 1 case of stromal tumors and 1 case of neurofibroma with the eggshell-like calcification; In CT enhancement cases, the thickening gastric wall with inhomogeneous enhancement; one case of glomus tumor mass with homogeneous enhancement; others showed mild or moderate enhancement. Conclusion The CT examination has important value in diagnosis of mesenchymal tumors.
