Case Discussion
A lingual thyroid is the most common location for ectopic thyroid tissue (90% of cases). During development, thyroid tissue migrates caudially within the midline from the foramen cecum.
Ectopic thyroid tissue may also be found in sublingual, prelaryngeal or mediastinal locations.
In children, a lingual thyroid may rarely cause airway compromise.
