Thyroglossal duct fistula
Updates to Case Attributes
Thyroglossal duct fistulafistulae have a typical course, extending uptoup to the foramen caecum of the tongue. It can be associated with a thyroglossal cyst.
MRI can be helpful in the presence of active discharge from the external opening. CT fistulogram will help define the entire length of the tract. In some cases, both CT and MRI are complementary to each other.

Updates to Study Attributes
The midline cutaneous opening in the infrahyoid neck was cannulated and 1cc1 cc of water soluble-soluble contrast was injected.
The fistulous tract extended superiorly from midline infrahyoid region, coursing along the anterior surface of hyoid bone and is seen extending uptoup to the foramen caecum of the tongue. The The tract measures 4.0 cmscm in length and 1.9mm.9 mm in diameter. There There is mild dilatation of the tract at the level of cutaneous opening measuring 5.0 x 2.8mm.8 mm. These features are consistent with thyroglossal duct fistula.
There is a blind ending-ending secondary oblique ramification of the tract in the tongue towards the left side. The secondary tract measures 1.3 cmscm in length and 2.0mm.0 mm in diameter.
No midline cystic lesion is seen in the neck. No significant lymphadenopathy.
