ectopic thyroid
Last reviewed 01/2018
A lingual thyroid occurs as a failure of normal descent of the thyroid and presentation as a lump in the foramen caecum or as a lump at the front of the neck near the body of the hyoid bone.
Any such lump should be investigated with a radio-iodine scan to ascertain whether it is a thyroid lump and if so whether it is the patient's only source of thyroid tissue.
