What is the classic presentation of a thyroglossal duct cyst?

A thyroglossal duct cyst typically presents as a midline neck mass that is located anterior to the trachea and thyroid gland. One of the defining characteristics of this type of cyst is its movement during swallowing, due to its connection to the hyoid bone and the underlying structures. As the patient swallows, the movement of the muscles and tissues in the neck causes the cyst to also move upward, reinforcing its midline positioning.

This movement is a crucial distinguishing feature of thyroglossal duct cysts compared to other neck masses, which may not exhibit this behavior. Understanding these specific physical characteristics plays a key role in diagnosing thyroglossal duct cysts and differentiating them from other conditions that may present as neck masses.
