He had a history of chronic hepatitis C. Computed tomography showed a liver tumor 20\u2009mm in diameter in segment 6 of the Couinaud classification, with ring calcification.

Partial hepatectomy was performed as a radical treatment for echinococcosis. A final diagnosis of hepatocellular carcinoma was confirmed based on pathological findings.
