Lingual thyroid in two natural brothers.
Tc99m scanning because of hypothyroidism revealed a lingual thyroid in two natural brothers who had no family history of thyroid disease. No thyroid tissue was found in the neck. Further development under substitution therapy with levothyroxine was normal. The diagnosis of this rare disease in two natural brothers suggests that lingual thyroid may be inherited.
