Imaging for thyroglossal duct cyst: the bare essentials

Abstract

Thyroglossal duct cyst is the most common congenital cyst in the head and neck, and imaging features have been well documented in the literature. However, there are several practical important points to bear in mind during preoperative imaging, which are often overlooked. This review aims to summarize the imaging findings and emphasize important points for trainees and radiologists, particularly those who may encounter this lesion infrequently.
