A thyroglossal cyst or thyroglossal duct cyst is a fibrous cyst that forms from a persistent thyroglossal duct.Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages.
Most commonly an ultrasound is performed to confirm the presence of a nodule, and assess the status of the whole gland. Measurement of thyroid stimulating hormone and anti-thyroid antibodies will help decide if there is a functional thyroid disease such as Hashimoto's thyroiditis present, a known cause of a benign nodular goitre.

Thyroiditis is generally caused by an immune system attack on the thyroid, resulting in inflammation and damage to the thyroid cells. This disease is often considered a malfunction of the immune system and can be associated with IgG4-related systemic disease, in which symptoms of autoimmune pancreatitis, retroperitoneal fibrosis and noninfectious aortitis also occur.
It’s estimated that nearly 5% of Americans above the age of 12 live with hypothyroidism, a condition that occurs when the body experiences a deficit of thyroid hormone.. The thyroid gland ...
During the third week of development, the thyroid gland begins to develop from the floor of the pharynx. This primordium begins as an evagination between the first and second pharyngeal grooves, relatively where the anterior two-thirds of the tongue ends. [4] This area is known as the foramen cecum and marks the origin of the thyroglossal duct ...
Hashimoto’s disease, also known as Hashimoto’s thyroiditis, is a condition where your immune system attacks your thyroid gland. This leads to hypothyroidism (an underactive thyroid ...
Occurrences of AIT are most common in patients with prior thyroid disease such as Hashimoto's thyroiditis or thyroid cancer. The most common cause of infection in children is a congenital abnormality such as pyriform sinus fistula. [5] In most cases, the infection originates in the piriform sinus and spreads to the thyroid via the fistula. [7]
Salivary glands, such as the submandibular gland or parotid gland, can become blocked by salivary stones. Dr. Lee says this can block the natural flow of saliva, causing facial swelling and pressure.
