Riedel's thyroiditis is a rare condition in which the thyroid gland is replaced by fibrous tissue. The case reported is one of Riedel's thyroiditis complicated by hypoparathyroidism and hypothyroidism. There would appear to have been only five earlier reports in the literature of hypoparathyroidism complicating Riedel's thyroiditis.
