| Sumario: | Lingual thyroid is a congenital anomaly caused by failure of migration of the thyroid gland in early embryogenesis. It may be asymptomatic or present with local symptoms. We present two cases with lingual thyroid, first one being in a 28-year-old female and the other in a 25-year-old male who had 20x15 mm and 33x30 mm masses respectively detected by magnetic resonance imaging. The diagnoses of lingual thyroid were confirmed by 99mTc pertechnetate scintigraphy. Thyroid function tests revealed hypothyroidism in both cases. Since most of the patients present with hypothyroidism, the diagnosis of lingual thyroid should be suspected especially in a case with local complaints. In routine examination of hypothyroid patients, palpation of the thyroid gland and ultrasonography must be included. A detailed examination of the neck and the base of the tongue must be performed in terms of lingual thyroid in patients with hypothyroidism and hypoplastic thyroid gland. |
