Abstract

Riedel's thyroiditis (RT) is a rare form of chronic thyroiditis characterized by extensive fibrosis of the thyroid gland, also affecting adjacent tissue, clinically resembles anaplastic thyroid or lymphoma. Findings from ultrasonography, and cytology are rarely conclusive. the therapeutic approach remains empirical and imperfect. We report a rare case of RT in a Moroccan woman with a good evolution after combined, surgical and medical therapy.
