摘　　要：目的：探讨肝细胞癌的大小与边缘部 CT征象及有关病理基础的关系。方法：收集 45例经手术、病理证实的肝细胞癌，观察其大小与边缘部的 CT表现及有关的病理改变。结果：肝细胞癌的大小与其 CT边缘部的形态改变及瘤旁小门静脉癌栓的发生率无关。病理上瘤旁周围肝组织内癌细胞的浸润程度与肝细胞癌边缘部的形态有关，而与它的大小无关。结论：肝细胞癌本身的膨胀性或浸润性生长方式，是决定肿瘤边缘部形态的主要因素；在分析肝细胞癌侵犯门静脉是否发生癌栓时，不能单凭肿瘤的大小或只注意门静脉主干及左、右分支的改变，而更重要的是要对瘤旁小门静脉癌栓的观察；肝细胞癌边缘部 CT的形态改变，对于术前预测瘤旁周围肝细胞内癌细胞的浸润程度有较大的帮助。Objective： The current study was designed to evaluate pathological significance of CT findings of the border region and size of hepatocellular carcinoma. Methods： Over all 45 cases of hepatocellular carcinoma were investigated, including their CT findings of the border region and size of the lesion as well as the pathological changes. Results： The size of lesion had no relationship with CT manifestations of the border region or the formation of malignant thrombi in the adjacent portal veinlet. The CT findings of the border region revealed that the histologically malignant involvement of the adjacent liver tissue correlated with the morphological appearance of the border region,but not the size of the tumor. Conclusion： The expansive or infiltrative growth of the hepatoma is a major factor influencing the morphological appearance of the border region. The CT findings of the border region reveal the portal system involvement adjacent to the lesions, which is more helpful than the evaluations merely based on the size of tumor and major branches of the portal vein. The analysis of the border region of the hepatocellular carcinoma is very useful in the pre- operative evaluation of the adjacent involvement of the hepatocellular carcinoma.
