Sonographically guided percutaneous ethanol treatment of a symptomatic complex nodule with a large cystic component in a patient with thyroid hemiagenesis.
Thyroid hemiagenesis is a rare anomaly that is usually discovered incidentally during the evaluation of unrelated thyroid disorders. We present the case of a patient with hemiagenesis of the left thyroid lobe and a large, recurrent, symptomatic complex nodule with a large cystic component that occupied most of the right lobe. She had previously undergone multiple unsuccessful aspirations of the cyst. The patient was successfully treated with an intranodular injection of ethanol under sonographic guidance. The success of this procedure resulted in the resolution of symptoms and avoidance of surgical resection of the right lobe, with resulting hypothyroidism. We recommend that ethanol injections be considered for treatment of symptomatic cystic or benign solid nodules in patients with thyroid hemiagenesis and in those who have undergone hemithyroidectomy and have symptomatic nodules.
