[Painful chronic thyroiditis. A rare cause of thyroid pain].
The usual clinical presentation of Hashimoto's chronic lymphocytic thyroiditis is a firm and painless goiter. We report two atypical observations with painful symptoms. Case 1: a 33 year old woman with a two months history of L-thyroxine treated primary hypothyroidism associated with elevated antithyroglobulin and antithyroperoxydase antibodies (respectively 36.000 and 7.000 U/l, normal values < 100 U/l) presents with anterior cervical pain. She is euthyroid, but displays biological inflammatory syndrome. Neck ultrasonography reveals low amplitude echoes of the thyroid gland. Antithyroid antibodies remain at high titers. After failure of NSAI drugs, prednisolone (oral 30 mg/day for 10 days, followed by degression) allows rapid disappearance of both pain inflammatory syndrome. When treatment was stopped pain recurred and required steroids for 3 months. After one year, the patient is painless and only receives L-thyroxine. Case 2: a 36 year old woman is referred for anterior neck pain, fever and hypothyroidism. Biological inflammation is also noted. High levels of antithyroglobulin and antithyroperoxydase antibodies are found. Thyroid uptake was maintained. L-thyroxine and prednisolone (oral 20 mg/day) therapies are associated with rapid pain relief. After two months, steroids are stopped. The patient remains normothyroid under L-thyroxine. Antithyroid antibodies persist at high levels. Other aetiological diagnosis of painful thyroid include acute infectious thyroiditis, cancers, intracystic hemorrhages and mainly subacute De Quervain's thyroiditis. Beyond clinical symptoms (revelation with hypothyroidism), persistent scintiscan uptake and prolonged elevated levels of antithyroglobulin and antithyroperoxydase antibodies remain the strongest arguments in favor of the 33 reported cases of painful Hashimoto's chronic lymphocytic thyroiditis. Eventually, among various therapies used, steroids in conjunction with thyroid hormones, seem the most efficient.
