【摘要】：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。
[Abstract]:Objective to investigate the CT findings of adult hepatoblastoma (HBB). Methods 9 cases of adult HB confirmed by operation and pathology were retrospectively analyzed. Ct plain scan and dynamic contrast enhanced CT scan were performed in 8 cases. Results the tumor was located in the right lobe of liver in 6 cases. There were 2 cases of Zuo Ye in the liver, 1 case involving the left and right lobe of the liver. 8 cases were single, 1 case was multiple in 9 cases, the density of tumor was uneven. 5 cases of necrotic cystic degeneration were found in all cases, 2 cases were accompanied with calcification and 7 cases had false capsule. No cirrhosis and vascular invasion were found in all the tumors. Intrahepatic bile duct dilatation and surrounding satellite lesions: one case with hilar and retroperitoneal lymph node metastasis. Ct enhanced enhancement of solid components and fibrous septum in the tumor area was uneven and progressive, and the enhancement degree was lower than that in the surrounding normal liver tissue, hemorrhage and necrosis. Conclusion Adult HB has some characteristic features on CT images, and combining with clinical features, it is helpful to improve the diagnostic accuracy of the disease.
