小儿肝母细胞瘤与肝细胞癌的CT及临床鉴别

目的：探讨肝母细胞瘤（HB）及儿童原发性肝细胞癌（IWC）的CT及临床特点,提高诊断水平。方法：回顾性分析经手术病例证实并行CT平扫及多期增强扫描的HB15例、HPCI2例,患者的资料。对各项临床及CT观察指标进行统计学分析。结果：HB多见于肝右叶,肿块多较大,多见坏死囊变,钙化多见;HPC多累计肝左右两叶,巨块型及巨块结节型多见,钙化少见,可见门脉血栓及淋巴结肿大。平均发病年龄、乙肝病毒感染率、肝硬化发生率低于肝细胞肝癌。结论：肝母细胞瘤及肝细胞癌为小儿最常见的两大恶性肿瘤,在临床及CT表现均有各自的特点,将各自特点综合分析,可在一定程度上将两者鉴别。

CT and clinic determination of pediatric hepatoblastoma and hepatic cell carcinoma

Objective：To discuss the CT and clinic characters of hepatoblastoma and pediatric hepatic cell carcinoma to elevate the diagnosis. Methods： Reviewed operational confirmed cases （with CT multi-period plain scan and enhanced scan） ： HB 15, HPC 12 information of the patients： to analyse clinic and CT indicators. Results： HB commonly found on right lobe with a huge size when necrosis, cyst and calcification can be found the HPC commonly found on both right and left lobes in massive type and massive-multifocal types with less calcification but PV thrombus and intumescent lymphonode. The mean age, rate of HBV infection and hepatic cirrhosis are less than hepatic cell carcinoma. Conclusion： In clinical and the CT manifestations all have the characteristics each other, the comprehensive analysis, could diffenential in certain ranges.
