Magnetic resonance imaging features of lingual thyroglossal duct cyst
Main Article Content
Abstract
This study aims to describe the magnetic resonance imaging features of the lingual thyroid cyst. This is a retrospective descriptive study of 29 patients harboring 29 lingual thyroid cysts based on MRI and confirmed by histopathology post surgery at the National Otorhinolaryngology Hospital from July 2019 to April 2021 . 19 (65.5%) lingual thyroid cysts are located in the midline. Twenty-seven (93.1%) cysts had moderate or high signal intensity on T1-weighted images. Twenty-five (86.2%) cysts compressed the epiglottis. The beak sign, the hyoid bone contact sign and tract sign were identified in 72.4%, 27.6%, and 17.2% of cysts, respectively. The majority of lingual thyroid cysts had high signal intensity on T1-weighted images, which is consistent with a high-protein content. The cysts usually extend into the vallecula and compress the epiglottis. The beak sign is common, the hyoid bone contact sign and the tract sign are uncommon. These imaging features are useful in making diagnosis and management of thyroglossal duct cyst.
