[摘要]目的:研究在螺旋
CT动态增强扫描中动脉期强化不明显肝脏占位性病变的CT表现,分析其特征 并进行鉴别。方法:收集118例在CT增强扫描中动脉期强化不明显肝脏占位性病变患者的资料,分析比较其基
本CT征象、特征性表现及强化方式。结果:118例肝脏占位性病变患者中,肝转移瘤40例,肝脓肿29例,肝
内胆管细胞癌21例,肝细胞癌17例,肝脏炎性假瘤6例,肝淋巴瘤5例;单发54例,多发64例;边缘清晰
24例,边缘模糊94例;病变位于肝右叶41例,肝左叶26例,肝左右叶50例,肝尾状叶1例;病变直径0.2
13.4cm。40例肝转移瘤均呈边缘轻度强化,“牛眼征”出现率为12.50% (5/40); 29例肝脓肿均呈环形、蜂窝
样强化,“双环征”和“气泡征”出现率均为13.79% (4/29) 17例肝内胆管细胞癌呈持续渐进强化,肝内胆
管扩张、肝包膜凹陷和病灶内钙化出现率分别为57.14% (12/21)、23.81% (5/21)和9.52% (2/21); 17例
肝细胞癌强化方式多种多样,肝脏形态轮廓改变、肝动脉扭曲增粗和血管受侵出现率分别为41. 18% (7/17)、
41.18% (7/17)和35.29%(6/17); 6例肝脏炎性假瘤中4例呈分隔以及结节样强化;5例肝淋巴瘤均呈轻度
均勻强化,“血管漂浮征”出现率为40.00% (2/5)。结论:螺旋CT检查动脉期强化不明显肝脏占位性病变时,
应结合CT征象及强化方式后进行综合判断,有助于为肝脏病变的定性及鉴别诊断提供重要依据。
