Riedel's thyroiditis, also called Riedel's struma is a chronic form of thyroiditis.

It is believed to be a form of autoimmune thyroiditis.[1]

Pathophysiology[edit]

Riedel's thyroiditis is characterized by a replacement of the normal thyroid parenchyma by a dense fibrosis that invades adjacent structures of the neck and extends beyond the thyroid capsule.[2] This makes the thyroid gland stone-hard and fixed to adjacent structures. The inflammatory process infiltrates muscles and causes symptoms of tracheal compression. Surgical treatment is required to relieve tracheal or esophageal obstruction.

It is now believed that Riedel's thyroiditis is one manifestation of a systemic disease that can affect many organ systems called IgG4-related disease. [3]


Prevalence[edit]

Riedel's thyroiditis is classified as rare.[4] Most patients remain euthyroid, but approximately 30% of patients become hypothyroid and very few patients are hyperthyroid. It is most seen in women.[5]

Treatment[edit]

Therapy usually consists of prednisone(?), nonetheless some cases may require surgery. Tamoxifen has been proposed as part of a treatment plan.[6]

Treatment is directed to surgical relief of compressive symptoms. Tamoxifen may also be beneficial. -Harrison's principle of internal medicine, 17th

The type of surgery which is indicated here is isthmectomy.

Eponym[edit]

It is named for Bernhard Riedel. He first recognized the disease In 1883 and published its description in 1896.[7][8]
