Thyroglossal duct cyst

A thyroglossal duct cyst is a cyst that forms on the base of your child's thyroid gland.

• Early in fetal life, the thyroid gland moves from the bottom of the tongue to the base of the neck.
• As the thyroid moves, it drags some of the lining of the pharynx, which can form a cyst.
• A thyroglossal cyst usually appears between ages 2 and 10.
• It is found equally in both girls and boys.
• The main risk of a thyroglossal duct cyst is infection. Bacteria from the mouth may cause the cyst to become infected.
