case_images: In the dynamic liver computed tomography (CT) scan, 12 x 9 x 6.5 cm3 irregular lobule contoured lesions extending to liver segments 4, 5 and 6 were clearly visible in the early arterial phase, with delayed phase contrast (wash-out phenomenon), causing pressure on the left portal vein and portal hilus, and it was initially evaluated favorable for hepatocellular carcinoma (HCC) (Figure 1A). Chemotherapy could not be continued due to resistant thrombocytopenia that developed after 6 months of treatment and newly developed lymph nodes (Figure 1B).
case_images: Dynamic CT scan images after TARE procedures.. Notes: Dynamic CT scan after TARE revealed a regressed mass with marked contrast (A). Dynamic CT scan after TARE revealed a mass with increased necrotic regions (B). Dynamic CT scan after TARE showed minimal regression (C).. Abbreviations: CT, computed tomography; TARE, transarterial radioembolization.

case_images: TARE (Figure 2) for 3 times without stasis in total and irinotecan-lipidol (100 mg) TACE for 4 times based on intermittent CT images for 40 months (Figures 2 and 3). The resinous radiomicrospheres were used in intra-arterial Y-90 microsphere treatment.
case_images: Based on the dynamic CT imaging obtained after the 2-step TACE procedure, a very large regression with peripheral hypodense necrosis areas was observed.. Notes: However, in segment 3, several lesions with the largest 3 cm were observed (A). Minimal shrinkage in the main mass dimension, extensive hypodense necrosis areas, and minimal increase in segment 3 lesions were observed according to dynamic CT findings after the 2nd and 4th TACE (B). Minimal regression was observed according to dynamic CT after 3rd TARE (C).. Abbreviations: CT, computed tomography; TACE, transarterial chemoembolization; TARE, transarterial radioembolization.
