摘要 目的:探讨非典型原发性肝细胞癌超声造影的特点及病理基础,提高超声诊断率。方法:回顾性分析11例经病理确诊原发性肝细胞癌住院患者的超声造影表现特点。结果:11例病理高分化HCC8例,中低分化HCC3例,病灶大小<3cm4例,3~5cm5例,>5cm2例。非典型超声造影表现包括增强方式和增强时相均不典型,前者包括增强信号呈斑片状不均匀低增强或不增强、周边环状增强、病灶内部一条或多条粗大滋养动脉贯穿病灶并形成树枝状分支非球状增强。增强时相不典型表现为病灶区与周围肝实质同步或晚于周围肝实质的低增强或门脉相低增强,但延迟相缓慢消退或未有明显消退。结论:11例非典型原发性肝细胞癌超声造影表现与肿瘤的分化程度、肿瘤内部的血流动力学特征密切相关,但最终明确诊断需要穿刺活检。
