Small hepatocellular carcinoma (sHCC, < 3 cm) is generally thought to have a good prognosis after surgical resection. However, the prognosis of patients with sHCC is still unsatisfactory because of frequent early recurrence (ER, <1 year) after resection. In our series, 30 % of patients with resected sHCC had ER. Preoperative MR imaging features (corona enhancement and irregular tumor margin) were independent predictors for ER after resection of sHCC.
