A thyroglossal cyst or thyroglossal duct cyst is a fibrous cyst that forms from a persistent thyroglossal duct. Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages.
Three-fourths of abnormalities within a persistent thyroglossal duct involve the formation of a cyst. [2] If a persistent thyroglossal duct becomes fluid filled it will form a thyroglossal duct cyst, which accounts for 70% of congenital neck masses and is the most likely diagnosis if the mass is along the midline of the neck.
