Study Notes
Riedel Thyroiditis
- Characterized by fibrous tissue replacing the thyroid gland, accompanied by an inflammatory infiltrate.
- Fibrosis can extend to nearby structures like the trachea and esophagus, potentially mimicking anaplastic carcinoma.
- Approximately one-third of cases present with hypothyroidism.
- May be a manifestation of IgG4-related systemic disease, a condition also linked to autoimmune pancreatitis, retroperitoneal fibrosis, and noninfectious aortitis.
- Physically, the goiter is fixed, hard (rock-like), and painless.
