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. [ 1 ] Thyroglossal cysts are the most common cause of midline neck masses and are generally located caudal to (below) the hyoid bone.
The thyroid gland is extremely painful, rigid, and swollen, which can be symmetrical or asymmetrical. [2] Approximately half of affected adolescents and two-thirds of adults have widespread thyroid gland involvement. [3] [5] Thyroid nodules are seen in one-fourth of adult patients. [6] The surrounding skin is occasionally warm and erythematous.
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. [4]
A goiter is a diffuse, often symmetric, swelling of the thyroid gland visible in the anterior neck that may develop. [13] The thyroid gland may become firm, large, and lobulated in Hashimoto's thyroiditis, but changes in the thyroid can also be non-palpable. [14] Enlargement of the thyroid is due to lymphocytic infiltration, and fibrosis. [15]
The pyramidal lobe is a remnant of the thyroglossal duct, which usually wastes away during the thyroid gland's descent. [5] Small accessory thyroid glands may in fact occur anywhere along the thyroglossal duct, from the foramen cecum of the tongue to the position of the thyroid in the adult. [4]
A possible explanation for the mental symptoms of sub-clinical thyroid disease, might be found in the fact that the brain has among the highest expression of THR's [clarification needed], and that neurons are often more sensitive than other tissues to thyroid abnormalities, including sub-clinical hyperthyroidism and thyrotoxicosis.
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.
As the developing thyroid begins to travel to its intended destination, it remains connected to the tongue via the thyroglossal duct. By the seventh week of fetal development, the thyroid reaches its final position in the neck after growing through the mesoderm and musculature of the tongue, mouth, and neck. During the eighth to tenth week, the ...
