Presentation
Fluctuant left sided neck mass, which moves on swallowing.
Patient Data
Large mass in the left anterior neck. No overlying skin abnormality.
The mass was partly compressible on probe palpation and moved on swallowing.
* written consent for clinical images ascertained.





3 cm well-defined thin wall cyst left of the midline. No solid components.
Normal thyroid gland.
FNAC/aspiration confirmed the radiological inference of a thyroglossal cyst.
Case Discussion
Thyroglossal duct cysts develop in the remanent of the thyroglossal duct. It can therefore develop anywhere in the line from the foramen cecum at the base of the tongue to the thyroid bed. The commonest site is at the level of the hyoid bone (half) as in this case.
