Thyroglossal Duct Cyst

Findings:

Axial neck CT images with contrast demonstrate a fluid density lesion at midline embedded within the strap muscles, displacing the adjacent strap muscles. The lesion is just below the level of the hyoid bone with a small suprahyoid extent into the pre-epiglottic fat.

Differential Diagnosis:

Thyroglossal duct cyst (by far most likely by location and characteristics), lymphangioma, necrotic lymph node, other duplication cyst much less likely.
