Abstract

A lingual thyroid is a rare developmental anomaly caused by the failure of the descent of the thyroid gland anlage early in the course of embryogenesis. The incidence of lingual thyroid has been reported to be 1/100,000. Lingual thyroid is often asymptomatic but may cause dysphagia, dysphonia, upper airway obstruction and hemorrhage. In this report, we described the case of a 50-year-old women experiencing lingual thyroid who had subclinical hypothyroidism. She underwent successful 131I ablation and has done well on thyroid hormone replacement therapy.
