Abstract: Objective:To invetigate the MSCT features of pedunculated hepatocellular carcinoma.Methods:12 cases of pedunculated hepatocellular carcinoma proved by angiography were collected,including 8 males and 4 female aged from 19 to 56 years old,the average age is 37.5 years old.All patients had underwented CT scan,enhance and three-dimensional reconstruction.To analysis of three-dimensional reconstruction of MSCT for diagnosis of pedunculated hepatocellular carcinoma.Result:In this group of 12 cases of pedunculated hepatocellular carcinoma,8 cases showed cirrhosis of the liver tumor is located beside the left lobe of lver in 6 cases,right lobe of liver adjacent to 5 cases,1 case next to the caudate lobe;5 cases with cystic mass in the main,7 cases with solid part of the main rare cystic;Arterial phase MSCTA showed 6 cases of blood from the right hepatic artery,4 cases of blood from the left hepatic artery,1 case from the right gastric artery,1 case from the stomach and duodenum artery.12 patients in this group were no portal vein tumor thrombus formation.Conclusion:Three-dimensional reconstruction of MSCT can show feeding arters of liver cancer,which has important diagnosis value of pedunculated hepatocellular carcinoma.
