Mr. Johnson presents a freely movable cystic mass in the midline of the high neck region at he base the tongue. This is most likely a Thyroglossal duct cyst.
<h3><u>
Explanation:</u></h3>
A thyroglossal cyst is a mass or lump of tissue formed at the base of the neck. Slowly it leads to the formation of the thyroid gland and leads to swelling. This leads to a high neck region at the bottom of the tongue. This usually occurs during birth.
It causes difficulty in breathing and swallowing of food. Infection may occur when it is untreated. Cyst formation takes place if the thyroid reached the final stage and the duct doesn't disappear. The cyst grows and causes an enlargement in the neckline.
