Developmental morphological abnormalities of the thyroid gland are very rare. Thyroid lobe hemiagenesis is a very rare abnormality, in which one thyroid lobe fails to develop. Ectopic thyroid is one of the common developmental anomalies of thyroid characterized by the presence of thyroid tissue in a site other than its usual. Of all, lingual thyroid is the most common manifestation of benign ectopic thyroid tissue, but it is still a rare clinical entity. Both of them seen together is even rarer. These developmental defects may or may not be associated with thyroid dysfunction. Ultrasonography (USG) is the initial modality of choice for thyroid hemiagenesis but further evaluation by computed tomography (CT) scan or nuclear scan should be done to look for other thyroid ectopic tissue rest. We report a case of right thyroid hemiagenesis with ectopic lingual thyroid in a 13-year-old female. To the best of our knowledge, only two similar cases in the world literature have been reported till date.
