Abstract
We report a successfully treated case of recurrent benign thyroid nodule using percutaneous ethanol injection therapy (PEIT). The patient was a 64-year-old man who had undergone right lobectomy of the thyroid due to follicular adenoma 5 years previously. After surgery, a large mass of the anterior neck was discovered. Ultrasound revealed a large cystic nodule, 5.5cm in diameter, in the left lobe of the thyroid. Although aspiration of cystic fluid was repeated five times, it returned rapidly to its initial level. Subsequently, compression symptoms such as swallowing disturbance and visible disfigurement occurred. After one trial of PEIT, tumor volume markedly decreased to 0.6 cm in diameter and compression symptoms disappeared. Therefore PEIT would appear to be a safe, simple, and effective procedure for recurrent benign thyroid nodules and may improve the patient's quality of life.
