Abstract

Management options for benign, autonomously functioning, and malignant thyroid nodules were limited to surgery or targeting by radioactive iodine before the availability of radiofrequency ablation (RFA). Despite being a relatively new technique, RFA may be favored for patients of high surgical risk, and for those who wish to avoid hypothyroidism. Although insurance coverage for the procedure can be a significant barrier, several groups of investigators have shown improved quality of life for RFA compared to surgery, due to the less invasive nature and favorable risk profile. Hyperthyroidism due to transient thyroiditis is a known risk of RFA, secondary to direct trauma and subsequent thyroid hormone release. Here we present a case of an adult with large, symptomatic, multinodular goiter, with no prior history of thyroid autoimmunity, who underwent RFA with successful volume reduction of two nodules, but who developed acute hyperthyroidism due to Graves disease eight weeks after RFA. Larger studies evaluating the risks of RFA should evaluate for incident hyperthyroidism, specifically for Graves disease/thyroid autoimmunity, as this could represent an additional risk of the procedure.
