Case contributed by Mohammadtaghi Niknejad



Patient Data

Age: 35 years
Gender: Female

CT of the neck with contrast showing an enhancing, well-circumscribed cystic lesion located in the neck at the level of the hyoid bone.

Case Discussion

The findings of the CT are compatible with complicated thyroglossal duct cyst.

Thyroglossal duct cysts are the most common cause of midline neck masses and typically located inferior to the hyoid bone (65%) in the region adjacent to the thyrohyoid membrane. Frequently presenting as an asymptomatic neck mass in the pediatric population, the most common presentation in adults is underlying infection of the cyst.
