Thyroglossal duct cysts are the most common type of congenital neck cysts and pediatric neck masses. They are typically located in the midline and are the most common midline neck mass in young patients. They can be diagnosed with multiple imaging modalities including ultrasound, CT and MRI.
CT scans and MRI can be used to evaluate thyroglossal duct cysts and the presence of normal thyroid tissue, but ultrasound alone in usually sufficient. Some surgeons advocate for routine thyroid function testing preoperatively.
BACKGROUND AND PURPOSE: Previous reports have suggested that thyroglossal duct cysts (TDCs) appear on sonograms as well-defined cystic masses with thin walls and posterior enhancement. In our experience, however, TDCs have a variable sonographic appearance.

Diagnosis of a neck mass such as a thyroglossal duct cyst is relatively easily made based on its location and sonographic characteristics. Although the thyroglossal duct cyst in this case was not noted to have laryngeal invasion, its effect on the patient’s vocal cords was unusual.
Purpose: The purpose of this study was to identify ultrasonographic features that can be used to differentiate between thyroglossal duct cysts (TGDCs) and dermoid cysts (DCs).
Thyroglossal duct cyst (TDC) is usually diagnosed clinically, but ultrasonography is the preferred imaging technique in children. The 2 most common complications of TDC are infection and...
In this radiology lecture, we review the ultrasound appearance of thyroglossal duct cyst with two unique cases!
How is a thyroglossal duct cyst diagnosed in children? After examining your child’s neck and throat, the doctor will usually perform an imaging test to get a detailed view of the cyst. Based on these images, the doctor can diagnose the thyroglossal duct cyst.
Familiarity with the course of thyroid primordium from the base of the tongue to the infrahyoid neck is helpful for recognizing ectopic thyroid tissue and thyroglossal duct cysts.
