Thyroid hemiagenesis is a rare congenital anomaly in which one thyroid lobe fails to develop. Tc-99m pertechnetate scintigraphy and ultrasonography can be used to visualize this anomaly, The authors evaluated four cases with Tc-99m pertechnetate scintigraphy and ultrasonography and confirmed thyroid hemiagenesis. In one case, a Tc-99m MIBI scan excluded the suppression of the contralateral thyroid lobe. Tc-99m MIBI can be used to confirm the diagnosis of thyroid hemiagenesis.
