Factors Influencing a Favorable Outcome for RFA of Huge Benign Thyroid Nodules: Preliminary Results and Short-Term Evaluation

Figure 2

(a) Prior to RFA treatment, the 66-year-old with a heterogeneous echogenicity huge thyroid nodule on the left side of the neck region. (b) During the RFA treatment, the transisthmic approach was used by passing through the thyroid parenchyma, and the nodule was sequentially ablated using the moving shot technique until the visual fields of the nodule had changed to transient hyperechoic zones. (c) 1-month post-RFA treatment. (d) 3-month post-RFA treatment. (e) 6-month post-RFA treatment, revealing a distinct reduction in size.
