Double thyroglossal duct cyst derived from a single tract: a rare presentation

Thyroglossal duct cysts are one of the most common congenital pathologic findings in children's cervical area. This type of cyst can be located anywhere between the base of the tongue and the sternal manubrium. We report the case of a patient with a double thyroglossal cyst, located inferior to the hyoid bone. The 2 cysts were connected by a common permeable tract, which confirms that an evolution failure of the embryonic remnants of the thyroglossal duct has been responsible for the development of such a cyst. Our case is the second case of double thyroglossal duct cysts and the first of double cysts located in the neck outside the thyroid gland
