Recurrence of hepatocellular carcinoma with rapid growth after spontaneous regression

Figure 1 Enhanced computed tomography (CT). A: A low-density mass located in liver S4, with marginal enhancement and a cystic mass of 68 mm × 55 mm in S6. B: Lipiodol accumulation in the tumor in S4 and the cystic mass in S6. C: Microwave coagulation performed for HCC in S4 during cholecystectomy. D: Further decrease in tumor size and enhanced area at the posterior cystic lumen of the tumor. E: Extension of the enhanced area to the surrounding area of cystic tumor. F: A well-differentiated HCC shown by histological evaluation.

Figure 2 A: Celiac arteriogram showing tumor stain with a size of 25 mm × 20 mm in S4. B: Blood supply of right hepatic lobe by the replaced right hepatic artery. C: Super mesenteric arteriogram demonstrating two tumor stains.
