A case of Riedel's thyroiditis / 대한외과학회지

ABSTRACT

Riedel's thyroiditis is an extremely rare disease that is difficult to diagnose correctly using preoperative diagnostic tools because it can mimic malignant neoplasm or the fibrous variant of Hashimoto thyroiditis during preoperative physical, radiologic, and pathologic examination. We describe here a rare case of Riedel's thyroiditis in an elderly patient and its radiologic characteristics.
