Thyroglossal duct cyst

What are the symptoms of a thyroglossal cyst?

• The cyst is seen as a mass in the middle of the neck.
• It's round and firm with no opening.
• The cyst usually does not cause any pain.
• The cyst moves up when the tongue is stuck out of the mouth or with swallowing.
• Occasionally the cyst can be seen to one side or other of the breathing tube.
• Bacteria from the mouth may infect the thyroglossal duct cyst, which can cause sudden swelling of the cyst and redness or tenderness in the area of the cyst.
