[2025-09-30T13:28:58.643775] [PI reasoning] **Evaluating thyroglossal duct cyst statements**

I’m looking to identify which statement about thyroglossal duct cysts is false. I recall that these cysts are congenital midline neck masses that often form due to the persistence of the thyroglossal duct. Most commonly, about 60-80% are located infrahyoid. The statement about 40% having a sub-hyoid location seems inaccurate since it's more like 65%. Additionally, it appears that they can be lined by pseudostratified columnar epithelium, so that statement is true.
