摘　　要：目的　研究亚病灶肝细胞癌变的发育不良性结节 (DN SF HCC)的CT表现和诊断。方法　回顾性分析 3个病理确诊的DN SF HCC者的CT资料。结果　在常规的UCT和增强CT上呈“混杂 等”、在螺旋CT的UCT、HACT、PVCT和DCT上分别呈“高 高 等”和“低 高 等 等”密度者各 1例 ;1例确诊 ,2例诊为肝癌。结论　DN SF HCC的CT表现多种多样 ,为提高诊断水平 。Objective To evaluate the CT findings and diagnosis of the dysplastic nodule with subfocus of hepatocellular carcinoma (DN-SF-HCC). Methods The CT data of three cases of DN-SF-HCC that diagnosed pathologically were reviewed retrospectively. Results In one case, the focus was showed as mixed and iso-density on the pre-and post-enhanced CT scans respectively, in 2 cases, the foci were showed as ”high-high-iso” and ”low-high-iso-iso” (one case) density on the plain, arterial-portal-delayed (one case) phase of the spiral enhanced CT scans respectively. One case was diagnosed correctly and 2 cases were diagnosed as hepatocellular carcinoma. Conclusion The CT features of the DN-FS-HCC were variable, further research is necessary in order to get correct diagnosis.
