Abstract
Purpose : To describe the radiologic features of computed tomography(CT) in hepatocelluar carcinoma(HCC) with bile duct involvement. Materials and Methods : We retrospectively analyzed the two phase spiral CT findings of 31 patients in whom HCC with bile duct invasion (n=28) or compression (n=3), was diagnosed. Eight of these underwent follow-up CT after transarterial chemoembolization. We analyzed the size, type, location, enhancement pattern, and lipiodol retention of parenchymal and intraductal masses, as well as their and lymphadenopathy. Results : In all patients with bile duct invasion, single or multiple masses were demonstrated in the bile ducts. Intraductal masses showed the same enhancement characteristics as the parenchymal mass (kappa 0.550, p
