lesion with subcapsular hematoma. After the first radio-frequency
ablation, MR imaging obtained 10 days after radio-frequency
ablation shows an ablation defect with a diffuse, ill-defined
enhancement around the defect. These findings were indeterminate.
MR imaging obtained 3 months after the radio-frequency ablation
shows a nodular contrast enhancement in the border of the
tumor with irregular shape contrast enhancement with nodular
pattern. Incomplete ablation of a large HCC lesion.
