De Quervain's thyroiditis, also known as subacute granulomatous thyroiditis or giant cell thyroiditis, is a self-limiting inflammatory illness of the thyroid gland. [1] De Quervain thyroiditis is characterized by fever, flu-like symptoms, a painful goiter, and neck pain.
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.
