A thyroglossal cyst can develop anywhere along a thyroglossal duct, though cysts within the tongue or in the floor of the mouth are rare. [citation needed] A thyroglossal cyst will move upwards with protrusion of the tongue. [citation needed] Thyroglossal cysts are associated with an increased incidence of ectopic thyroid tissue.
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.

Long-standing infected thyroglossal duct cyst in a 29-year-old male patient. a Transverse greyscale ultrasound at midline, just above the level of the thyroid gland, shows an oval cystic lesion with internal echoes (white arrows) and posterior enhancement (arrowheads). b Transverse colour Doppler ultrasound shows surrounding peripheral flow ...
The thyroglossal duct is an embryological anatomical structure forming an open connection between the initial area of development of the thyroid gland and its final position. It is located exactly mid-line, between the anterior 2/3 and posterior 1/3 of the tongue .
There are many different possible causes, [1] including head and neck cancer [2] and congenital conditions like branchial anomalies and thyroglossal duct cysts. [ 3 ] Diagnosis
