目的:探讨MSCT对肝外型肝癌的影像诊断。方法:搜集经手术病理证实的肝外型肝癌12例,其中男性8例,女性4例,年龄19～56岁,平均年龄37.5岁。所有病例均行CT平扫、增强及三维重建。分析MSCT三维重建对肝外型肝癌的诊断价值。结果:在本组12例肝外型肝癌中,8例存在肝硬化。肿块位于肝左叶旁6例,肝右叶旁5例,尾状叶旁1例;肿块5例以囊变为主,7例以实性部分为主,少有囊变;动脉期MSCTA显示6例由肝右动脉供血,4例由肝左动脉供血,1例由胃右动脉供血,1例由胃十二指肠动脉供血。本组12例均未见门静脉瘤栓形成。结论:MSCT三维重建可以显示肝癌的供血动脉,对肝外型肝癌有重要的诊断价值。
Objective: To investigate the imaging diagnosis of extrahepatic liver cancer by MSCT. Methods: 12 cases of extrahepatic hepatocellular carcinoma confirmed by pathology were collected, including 8 males and 4 females, aged from 19 to 56 years, with an average age of 37.5 years. CT scan in all cases, enhanced and three-dimensional reconstruction. To analyze the value of MSCT 3D reconstruction in the diagnosis of extrahepatic liver cancer. Results: Among the 12 cases of extrahepatic liver cancer in our group, cirrhosis was found in 8 cases. The tumor was located in the left lobe of the liver in 6 cases, in the right lobe of the liver in 5 cases and in the caudate lobe in 1 case. The tumor was mainly cystic in 5 cases, with solid part in 7 cases and few cystic changes. The arterial phase MSCTA showed 6 cases were supplied by the right hepatic artery, 4 cases by the left hepatic artery, 1 case by the right gastric artery and 1 case by the gastroduodenal artery. No group of 12 cases of portal vein tumor thrombus formation. Conclusion: Three-dimensional reconstruction of MSCT can show the donor artery of liver cancer, which has important diagnostic value for extrahepatic liver cancer.
