A Unique Case of Hepatocellular Carcinoma Treated with Radiofrequency Ablation with More than 12 Years Overall Survival: A Case Report
Figure 2
(a) After 18 months, a new CT scan depicted a local tumor progression at the ablation site. Note the unenhanced area of the lesion corresponding to the ablated site (long arrow) and the local tumor progression seen as an adjacent hypodense area (short arrow). (b) Similar to findings on the MRI scan, the ablated area shows no signal (long arrow), whereas the local tumor progression appears as a low signal area (short arrow).
