Antithyroid Arthritis Syndrome | Biomedgrid

Antithyroid arthritis syndrome is a rare adverse effect with a series of symptoms of fever, arthralgia, myalgia and arthritis. We report a case of a patient with hyper-thyroidism, who presented with Antithyroid arthritis syndrome after being treated with methiamazole and describe the diagnosis, treatments, follow-up of the case. Our aim is to increase awareness of this uncommon but life-threatening adverse effect when diagnosing patients who develop arthritis after being treated with Antithyroid in clinical practice.
