摘　　要：目的:探讨肝细胞癌肝实质一过性异常强化的影像学特征及病理改变。方法:选择肝脏动态增强CT扫描肝细胞癌合并肝实质一过性异常强化征象病例21例,以肝实质一过性异常强化区域为研究对象,并通过手术切除和CT引导下穿刺活检的方法进行病理检查。结果:肝实质一过性异常强化征象表现为肿块以外肝实质动脉期显著强化,门静脉期或延迟期呈等密度,楔形或三角形13例,不规则形9例,叶段形6例。肝实质一过性异常强化征象与癌细胞向周围扩散和肝内转移无相关性。结论:明确肝细胞癌肝实质一过性异常强化的形成机制及病理基础,有助于肿瘤的分期和制定治疗方案。Objective：To investigate the imaging feature and the pathology of transient hepatic abnormal enhancement （THAE） with hepatocellular carcinoma during dynamic contrast-enhanced spiral CT. Methods： Twenty-one patients with transient hepatic abnormal enhancement in the hepatic arterial phase during dynamic contrast enhanced spiral CT, had the pathological examination in the locality of THAE sign by operation or percutaneous puncture. Results： All of THAEs sign was the hepatic parenchyma which outside the tumor that imaging showed homogeneous hyperattenuating in hepatic arterial phase, and changed to isoattenuating in the portal venous phase and delayed phase. Wedge-shaped or fan-shaped in 13 cases, irregular shape in 9 cases, hepatic segment shaped in 6 cases. It had no correlation between the transient hepatic abnormal enhancement sign and the infiltration of cancer cell in liver. Conclusion： To definitude the come into being mechanisms and pathology of transient hepatic abnormal enhancement （THAE） with hepatocellular carcinoma, is helpful in confirming the stages of hepatocellular carcinoma and treatment project.
