Figure 2: Case no. 2: 62-year-old female patient had a focal lesion on top of cirrhotic liver. (a) arterial phase baseline triphasic computed tomography. (CT): an ill-defined heterogeneously enhanced mass measuring 6 cm at segment VIII. (b) Portal phase baseline CT: contrast washout of the mass. (c) Digital subtraction angiography through the common hepatic artery using a cobra catheter. (curved arrow) with superselective catheterization of the feeding vessel showing proper lipidol retention by the mass. (long arrow); the short arrow indicates the inserted RFA needle. (d) Ultrasound. (U/S)-guided RFA of the lesion: the electrode appears as an echogenic line (arrow). (e) Arterial phase triphasic CT 4 weeks after TACE–RFA: adequate opacification of the lesion by lipidol with no evidence of residual enhancing tissue. (f) Portal phase triphasic CT 1 month after TACE–RFA: no evidence of washout. (arrows). Note the gas foci within the lesion. (curved arrow) indicating abscess formation. (complete response on mRECIST). RFA, radiofrequency ablation; TACE, transarterial chemoembolization.
