Sonographic Assessment of a Thyroglossal Duct Cyst

Thyroglossal duct cysts account for most diagnosed midline neck masses. They generally sit at or below the hyoid bone. They can vary in appearance and area of infiltration, although few cases of laryngeal involvement have been reported. Sonography is the modality of choice for imaging these cysts, followed by a Sistrunk procedure to remove the cyst. This case report focuses on the sonographic appearance of these cysts and their management.
