目的探讨成人肝母细胞瘤(HB)的CT表现。方法回顾性分析9例经手术病理证实的成人HB患者资料,8例患者行CT平扫和动态增强扫描检查,1例行CT平扫检查。分析其影像特征。结果肿瘤位于肝右叶6例,肝左叶2例,累及肝左右叶1例。单发8例,多发1例。9例肿瘤密度不均,均可见坏死囊变,5例伴有出血,2例伴有钙化,7例肿瘤有假包膜。所有肿瘤均未见肝硬化、血管侵犯、肝内胆管扩张及周围卫星灶征象,1例伴有肝门及腹膜后淋巴结转移。CT增强扫描肿瘤区实性成分及纤维间隔呈不均匀渐进性强化,强化程度低于周围正常肝组织,出血、坏死、囊变区未见明显强化。结论成人HB在CT图像上具有一定的特征性表现,再结合临床特点,有助于提高该病的诊断准确率。
Objective To investigate the CT findings of adult hepatoblastoma (HB). Methods Retrospective analysis of 9 cases of pathologically proven HB patients, 8 patients underwent CT scan and dynamic contrast-enhanced scan, 1 case of CT plain scan. Analyze its image features. Results The tumor was located in 6 cases of right lobe, 2 cases of left lobe and 1 case of left and right lobe. A single hair in 8 cases, multiple cases in 1 case. 9 cases of tumor density uneven, necrotic cyst can be seen in 5 cases with bleeding, 2 cases with calcification, 7 cases of tumor with a pseudocapsule. All the tumors showed no liver cirrhosis, vascular invasion, intrahepatic bile duct dilatation and signs of nearby satellite lesions. One case had hepatic hilar and retroperitoneal lymph node metastasis. CT enhanced scan of the tumor area of solid composition and fiber interval was unevenly progressive enhancement, the degree of enhancement is lower than the surrounding normal liver tissue, bleeding, necrosis, cystic area was not significantly enhanced. Conclusion Adult HB has some characteristic features in CT images. Combining with clinical features, HB helps to improve the diagnosis accuracy of the disease.
