Riedel's thyroiditis shows several features that justify its inclusion into the spectrum of IgG4 related disease (IgG4-RD).
Fine needle aspiration was suggestive of Riedel's thyroiditis. The CT scan confirmed a large thyroid lesion with esophageal invasion and decreased tracheal lumen of about 50% (Figure 1).
The intraoperative frozen section exam confirmed the diagnosis of Riedel's thyroiditis.
Having Riedel's thyroiditis means Jean can't eat, as food gets stuck in her throat, which swells and is painful to touch.
Thanks to Jean's efforts in contacting the charity, Thyroid UK have now included information about Riedel's thyroiditis on their website.
Riedel's so rare RIEDEL'S thyroiditis is a very rare form of thyroid disease which causes scarring of the connective tissue that replaces normal thyroid tissue.
In patients with Cowden's syndrome, retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, Riedel's thyroiditis, and inflammatory pseudotumor of the orbit can all manifest, either alone or in combination.
Findings suggesting that retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, Riedel's thyroiditis, and pseudotumor of the orbit may be different manifestations of single disease.
