Novel approach of thyroid radiofrequency ablation for huge nodules-Eggshell technique (evenly margin-preserving ablation): a case report.

ABSTRACT:

Background

Radiofrequency ablation (RFA) for huge thyroid nodules often requires multiple sessions to achieve long-term efficacy. We present our experience with a stepwise approach utilizing a nodule margin-preserving ablation, termed the Eggshell technique, in the treatment of a thyroid nodule exceeding 9 cm in diameter.

Case description

A 44-year-old woman presented with compressive symptoms due to a large left thyroid solid nodule measuring 5.81 cm × 3.19 cm × 9.26 cm, with a volume of 90.84 mL. Cytopathology, including core needle biopsy, confirmed Bethesda Category II in two separate evaluations. RFA was performed under local anesthesia using the Eggshell technique, which preserved the nodule margin while ablating the internal tissue. The procedure lasted 83 minutes, de
