OTHER CYSTIC NECK MASSES
• Thyroglossal duct cysts are benign congenital cysts located within the midline of the neck superior to the thyroid gland and near the hyoid bone.
• They typically are asymptomatic, though they may become painful when inflamed.
• Sonographically, a thyroglossal duct cyst will appear as an anechoic well-defined unilocular cyst with posterior enhancement.
• Brachial cleft cysts are congenital neck cysts as well.
• They are found most often near the angle of the mandible and appear as an anechoic mass with posterior enhancement.
