Thyroid hemiagenesis is a rare anomaly characterized with the absence of one thyroid lobe due to a failure in embryologic development of the thyroid gland. This anomaly is more frequent in women. It usually affects left side of the thyroid. Isthmus may be detected in half of the cases. Thyroid hemiagenesis is usually diagnosed after thyroid imaging due to other disorders, which might be related or unrelated to the thyroid gland. In this paper, we report clinical features of twelve patients with thyroid hemiagenesis who were diagnosed during the period of five years in Dokuz Eylul University Hospital Endocrinology Clinic.
