Abstract

OBJECTIVE:

Thyroglossal duct cysts are the most common congenital neck mass. They typically present as a painless midline neck mass in a child or young adult, but may also present later in adulthood when the cyst becomes symptomatic. Thyroglossal duct cysts are most commonly located inferior to the hyoid bone in close relation with the thyrohyoid membrane. Very rarely, they may extend intralaryngeal, occupy the posterior hyoid space, and present with dysphonia and/or dysphagia. To our knowledge, this is the 24th reported case in the literature.

METHODS:

Case report with a comprehensive review of the literature.

RESULTS:

The patient was a 43-year-old male experiencing dysphonia and dysphagia following a motor vehicle accident. He was subsequently found to have a large thyroglossal duct cyst with endolaryngeal extension that was previously asymptomatic and undiagnosed. He underwent successful surgical excision which resulted in resolution of symptoms.

CONCLUSION:

This is the first reported case of a thyroglossal duct cyst in the posterior hyoid space with endolaryngeal extension being diagnosed following a traumatic event. This case illustrates the need to consider thyroglossal duct cyst in the differential diagnosis when working up a post-traumatic intralaryngeal neck mass. A secondary educational objective in this case is to be diligent to consider and rule out laryngeal fracture in the case of a neck mass presenting after trauma as they can easily be missed and present with many overlapping symptoms.
