目的：探讨肝硬变并发肝癌的ＣＴ表现特点，提高诊断水平。方法：收集３００例肝硬变中合并肝癌的１４５例ＣＴ资料，从肿瘤类型、肿瘤部位、肿瘤及其并发症的ＣＴ表现等方面进行回顾性分析。结果：１４５例肝癌中巨块型８６例，结节型４６例，弥漫型１３例。４６．２１％肿瘤出现在肝硬变萎缩的肝叶。较小的肿瘤或弥漫型肿瘤平扫时显示不清。结论：肝硬变合并肝癌的肿瘤类型及大部分肿瘤的ＣＴ表现与一般肝癌没有明显差别；小的或弥漫型肝癌要通过强化扫描或进一步检查才能确诊；ＣＴ扫描比较容易区别肝硬变或门脉癌栓引起的门脉高压。
Objective: To investigate the CT features of liver cirrhosis complicated with hepatocellular carcinoma and to improve the diagnostic level. Methods: The data of 145 cases of cirrhosis with hepatocellular carcinoma collected from 300 cases were retrospectively analyzed in terms of tumor type, tumor location, CT findings of tumor and its complications. Results: Among 145 cases of hepatocellular carcinoma, 86 were bulky, 46 were nodular and 13 were diffuse. 46.21% of the tumors appeared in the liver lobe of atrophic cirrhosis. Smaller tumors or diffuse tumors show unclear during plain scan. Conclusion: There are no significant differences in the types of tumors and CT features of most of the tumors with cirrhosis and most of the tumors. The diagnosis of small or diffuse hepatocellular carcinoma can only be confirmed by intensive scanning or further examination. CT scan is easier to distinguish cirrhosis or portal disease Thrombosis caused by portal hypertension.
