We retrospectively evaluated the characteristic computed tomographic (CT) finding in nine patients withexohepatic hepatocellular carcinoma (HCC) pathologically prove by surgery (n=2) or percutaneous needle biop-sy(n=7). The CT findings of exohepatic HCC were correlated with clinical findings and compared with those of usual HCC. Lesions were in the left lobe (n=7) and right lobe(n=2) of the liver. All lesions showed a well-marginated hypodense mass with capsular enhancement on enhanced CT scan. The patterns of capsular enhancement were complete in five and partial in four cases. The portal vein thrombosis was seen only in one case. There was no difference between exohepatic HCC and usual HCC in clilnical findings such as increased $alpha$ -fetoprotein ($alpha$-FP), positive Hepatitis B surface antigen(HBsAg), and underlying liver cirrhosis. In conclusion, the CT findings of exohepatic HCC were a well-defined hypodense mass with complete ar partial capsular enhancement and these findings may be useful in differentiation from the tumors of adjacent organs.
