【摘要】 目的：描述肝母细胞瘤的影像学表现。材料和方法：回顾性分析 １４例经手术及穿刺病理证实的肝母细胞瘤患者，分析其临床实验室检查及影像学表现。 １４例均行超声检查， ３例行 ＣＴ检查， １１例行 ＭＲ检查。患者继往无肝炎及肝硬化史。血浆ＡＦＰ水平１３例（１１／１３）升高，１例（１／１３）正常。结果：超声检查肿瘤回声不均匀，中低混合性回声为主，２例（２／１４）夹杂斑片状强回声；ＣＴ平扫见边界清楚、不均匀低密度肿块，单发或多结节融合状，２例（２／１４）可见多发斑片状钙化；ＭＲＩ Ｔ１ＷＩ肿块信号低于肝实质， Ｔ２ＷＩ肿块信号高于肝实质，８例（８／１４）中心部坏死长 Ｔ１长 Ｔ２信号， ６例（６／１４）可见出血Ｔ１ＷＩ、Ｔ２ＷＩ高信号。结论：①初生至３岁前出现并急剧增大的肝脏肿大、右上腹包块，进行性全身衰竭者，应首先考虑肝母细胞瘤的可能；②肝母细胞瘤ＡＦＰ测定常明显增高；③肿块内斑片状钙化对于肝母细胞瘤诊断有重要意义。更多还原

【Abstract】 Objective:To describe the imaging findings of hepatoblastoma. Materials and Methods: Imaging studies in 14 cases with pathologically confirmed heptoblastoma were reviewed. Imaging studies included US in 14 cases,CF in 3 cases, MRI in 11 cases.There was no cirrhosis or hepatitis according to patients’ history. Serum a - fetoprotein level was normal in 1 case, high in 13 cases. Results: On US, the echogenicity of the tumor was non - homgeneous and iso - hypoechoic, there was punctate hyperechoic according with shadow in 2 cases. Nonenhanced CT scan demonstrated a well demarcated, solitary mass or a multilobulated mass. All masses were non - homogeneous and hypodense to the liver.There was punctate calcification in 2 cases.On MRI, the tumor was hypoindense relative to the liver parenchyma on T1 - weighted spin - echo image and non - homogeneous on T2 - weighted image. Conclusions: ①If pediatrics between infant to 3 - year old present with hepatomegaly and mass on the right - upper quarter of abdomen,we shall have in mind the diagnose of hepatoblastoma. ②Serum a - fetoprotein level significantly elevated in hepatoblastoma. ③It have more significance on the diagnose to find the punctate calcification in the mass.更多还原
