Thyroglossal Duct Cysts Picture

A fluid-filled sac present at birth in the midline of the neck. A thyroglossal cyst is
a congenital malformation (a birth defect). It results from incomplete closure of a
segment of the thyroglossal duct, a tube-like structure that normally closes as the embryo
develops. Also called a thyroglossal duct cyst. The picture below shows the
bulge in the neck caused by a Thyroglossal Duct Cyst.
