Abstract
HIFU is used in the treatment of cancer (prostate, breast) and uterine fibroma but not yet in TNs. This case report describes the first successful ablation of a toxic TN with HIFU. TSH and radioiodine scan normalization were achieved without complications and maintained for 18 months. HIFU treatment is a minimally invasive technique that may be an effective safe alternative to radioiodine or surgery in patients with toxic TNs.

Top, Transversal sonography scan shows a 9 × 8 mm solid isoechoic right isthmolobar nodule. Middle, Longitudinal power Doppler sonography shows hypervascularization before HIFU treatment. Bottom, Hot right isthmolobar nodule with near-total suppression of extranodular iodine uptake is shown by the 123I thyroid scan.
Recovery of extranodular iodine uptake 18 months after HIFU is shown by the 123I thyroid scan.
