ABSTRACT
Lingual thyroid is due to an aberration in the normal development of thyroid. Ectopic thyroid is defined as the presence of thyroid tissue in a location other than the normal anterior neck region between 2ndand 4th tracheal rings. It is due to a defect in thyroid diverticulum migrating from the base of the tongue, to its final pretracheal position. Here is a case of lingual thyroid presented as a swelling at the base of the tongue, of size 2x3cm since 2 months. Diagnosis of ectopic lingual thyroid was made. Tc99 pertechnetate radioisotopes can confirm ectopic lingual thyroid. There was no thyroid tissue in the normal location. Hence ectopic Lingual thyroid was the only functioning thyroid. Management was by Surgical excision of the gland and thyroxine replacement.
Key words: Lingual thyroid, Ectopic thyroid, Tc99pertechnetate scan
