Subacute Thyroiditis

(Granulomatous Thyroiditis; de Quervain Thyroiditis; Giant Cell Thyroiditis)

by Jerome M. Hershman, MD

Subacute thyroiditis (granulomatous thyroiditis) is acute inflammation of the thyroid, probably caused by a virus.

Subacute thyroiditis usually begins suddenly. In this disorder, inflammation causes the thyroid gland to release excessive amounts of thyroid hormones, resulting in hyperthyroidism (see Hyperthyroidism), almost always followed by transient hypothyroidism (see Hypothyroidism) and finally normal thyroid function.
