目的 :探讨儿童肝母细胞瘤的CT表现,评价其临床应用价值,以提高肝母细胞瘤CT诊断水平。方法 :回顾性分析本院20例经穿刺活检或手术病理证实的肝母细胞瘤CT表现。结果:肿瘤CT表现体积较大、不均匀低密度病灶,其中位于肝右叶11例,肝左叶5例,肝内弥漫性病变4例,11例肿块内见不规则钙化,增强扫描动脉期呈多个结节状或斑片状不均匀强化,密度低于肝组织,门脉期病灶呈低密度,其中10例肿块中见弥漫分布多发小囊,4例见包膜强化,3例瘤内可见迂曲血管。随访,2例发生肝内多发转移,5例发生肺部多发转移,1例发生肝门区、腹膜后多发淋巴结转移及门脉癌栓形成,伴有腹水1例。结论:CT是肝母细胞瘤有价值的影像学方法 ,能较好显示肿瘤的形态、大小及对血管的侵犯情况,对病灶的定位及定性较为准确,具有一定的特异性。
Objective: To investigate the CT findings of hepatoblastoma in children and evaluate its clinical value in order to improve the CT diagnosis of hepatoblastoma. Methods: A retrospective analysis of 20 cases of this hospital by biopsy or surgical pathology confirmed hepatoblastoma CT findings. Results: Tumor CT showed a large volume and uneven low-density lesions. Among them, 11 were located in the right lobe of the liver, 5 in the left lobe, 4 in the liver, and irregular calcifications were seen in 11 tumors. Showed multiple nodular or patchy heterogeneous enhancement, density lower than that of liver tissue, portal venous lesions showed low density, of which 10 cases were seen diffusely distributed cystic mass, 4 cases of enhancement of the capsule, 3 cases of tumor Inside the tortuous blood vessels can be seen. Follow-up, 2 cases of multiple intrahepatic metastases, 5 cases of multiple lung metastases, 1 case of hilar area, multiple retroperitoneal lymph node metastasis and portal vein thrombosis, with 1 case of ascites. Conclusion: CT is a valuable imaging method of hepatoblastoma. It can show the morphology, size and invasion of blood vessels well. The localization and characterization of the lesions are more accurate and have certain specificity.
