Overall, early 1C-D, respectively). There was no vascular invasion and no stage of HCC was assigned according to the Barcelona- intraabdominal lymphadenopathy. On positron emission tomo- Clinic-Liver-Cancer (BCLC) HCC staging system.1 graphy-CT, maximum standardized uptake value for the mass Surgical resection was recommended for the treatment of the B C D Figure 1. An irregularly enhanced mass measuring 5 cm in the caudate lobe with delayed wash-out was observed on dynamic CT (A: arterial phase, B: portal phase, coronal section). Similar signal intensity was noted on MRI (C: T1-weighted image, D: T2-weighted image). B C Figure 2. (A) Celiac arteriography showed a faint hypervascular tumor staining in the caudate lobe supplied by a branch from the left hepatic artery. (B) Selective left hepatic arteriography clearly demonstrated the tumor (arrow heads) and a single supplying artery branch (arrow) from the left hepatic artery. (C) Post-embolization celiac arteriography showed no more tumor staining and occlusion of the tumor supplying artery.
