摘要
目的:探讨肝母细胞瘤的临床及CT表现,以提高其诊断准确率。方法:回顾性分析经手术及病理证实的肝母细胞瘤13例,结合文献回顾性分析肝母细胞瘤的临床和CT表现。结果:肿瘤主体位于肝右叶10例,肝左叶2例,跨左右叶1例。肿块最大径约11~24cm,平均16cm。8例轮廓光滑,边界清楚,包膜较完整,5例部分边界不清。CT平扫肿瘤呈低、等混杂密度肿块,肿瘤内见裂隙状或不规则更低密度区,7例可见瘤内小斑点状或弧形钙化;增强扫描动脉期13例肿瘤呈不均匀性强化,分隔及周边的结节明显强化,但强化程度低于正常肝组织。坏死或液化区均无明显强化。门脉期8例瘤内分隔延迟强化。3例侵犯门脉血管。结论:CT能较好的描述肿瘤的范围、包膜的完整性,对肝内血管和下腔静脉的侵犯情况提供了较多的信息,对临床治疗方案的制定和预后起重要的作用。CT上肝母细胞瘤有一定的特征性,结合患者年龄、AFP可提供诊断的准确率。
Objective: To study the clinical features and CT appearances of hepatoblastoma(HB ). Methods: The CT findings and clinical data of the 13 pathology and surgery cenfirmed HB were retrospectively analyzed. Results: Ten tumors involved the right lobe, two involved the left lobe, and 1 involved beth liver lobes. The diameter was 16 em in average. In CT plain scan most of HB showed a slit- shaped or irregularly low density area in hypo-or isodensity solid mass. Seven eases showed mottling or curviliear calcification. Tumor showed moderate inhomogeneous and heterogenie enhanced. Eight intratumoral septal were delayed enhancement. Three showed portal vein infiltration. Conclusion: CT scan delineate the extent of HB, provide information of the liver vessels and inferior vena eava. CT was helpful in the diagnosis, monitoring and follow-up in HB patients. HB have some characteristic CT manifestations. Combination with the age and AFP can elevate the diagnosis accuracy.
