Figure 14. Computed tomography of axial planes obtained in noncontrast phase (A), arterial phase (B), portal phase in coronal plane (C) and axial plane in delayed phase (D). Hepatic mass (yellow arrow) hypodense in noncontrast phase (A), with heterogeneous peripheral enhancement in the arterial phase (B), and portal phase (C), and central uptake in delayed phase (D). This lesion corresponded to cholangiocarcinoma
