摘要 目的分析胃血管球瘤(GT)的临床表现及影像学特征。方法系统性回顾经病理证实的8例胃GT患者的临床资料及螺旋CT增强扫描的影像学表现。临床资料主要观察患者贫血、便潜血等情况。影像学表现主要观察肿瘤的部位、大小、形态、边缘情况、生长方式、平扫密度、是否有钙化、增强后强化程度及肿瘤表面是否有黏膜溃疡形成等。结果 8例患者均无贫血症状,便潜血实验阳性者4例。病变位于胃窦部7例,胃大弯区1例。8例肿瘤均位于胃壁内,呈类圆形,边界清晰,未见明显分叶,长径0.7~5.1cm,平均3.0cm。平扫CT值呈软组织密度,CT值25~44 HU,平均33 HU,2例肿瘤内可见细点状钙化。增强后肿瘤强化显著,2例肿瘤表面有黏膜溃疡形成。结论掌握胃GT的特征性临床症状及影像学表现对此病的临床诊疗有一定价值。
