Atrophic Thyroiditis: Causes, Symptoms, and Treatment

No, there are other such conditions. For instance, unlike atrophic thyroiditis which causes fibrosis limited to the tissue, Riedel thyroiditis (an extremely rare inflammatory condition) is defined by severe, invasive fibrosis that extends to nearby tissues. Also, while both conditions can lead to hypothyroidism, Riedel thyroiditis is more likely to present with a mass in the neck and compressive symptoms, making it clinically distinct from atrophic thyroiditis.
