Figure 3: Case no. 3: 56-year-old male patient discovered to have a right lobe focal mass. (a) Arterial phase baseline triphasic computed tomography (CT): well-defined heterogeneously enhanced mass measuring 5.5 cm at segment VII. (b) Delayed phase baseline CT: contrast washout occurs. (c) Ultrasound (U/S) liver: well-defined hypoechoic mass at segment VII. (d) U/S-guided RFA: the electrode appears as an echogenic line (arrow). (e) Arterial phase triphasic CT after TACE–RFA: adequate homogenous lipidol deposition with no contrast-enhanced residual tissue.(f) Delayed phase triphasic CT after combined RFA–TACE: no contrast washout occurs (arrow) (complete response on mRECIST). RFA, radiofrequency ablation; TACE, transarterial chemoembolization.
