Abnormalities in the embryologic development and migration of the thyroid gland can result in ectopic thyroid tissue. Ectopic mediastinal goiters are somewhat uncommon developmental anomalies, accounting for less than 1% of all thyroid ectopies. Graves' disease within mediastinal goiter is a very rare entity, described only in few cases in English literature. Pretracheal thyroidectomy alone does not cure Graves' disease and can stimulate growth of the ectopic tissue in such cases.
