    Abstract

    Thyroid hemiagenesis of one lobe of the thyroid is a rare congenital anomaly in which one lobe of the thyroid gland fails to develop. It is more frequently found in women than in men, and absence of the left lobe is more common. The variations of prevalence of the anomaly have been reported to be around 0.05~0.2%. Patients with thyroid hemiagenesis are usually asymptomatic and discovered incidentally with other pathologic condition such as a benign adenoma, multinodular goiter, hyperthyroidism or carcinomas. We report a 29-year-old woman with an incidentally discovered hemiagenesis of the right thyroid.
