A Rare Case of Bilateral Temporal Arteritis in a 40-year-old Patient

Temporal arteritis (TA) is a chronic inflammatory vasculitis involving medium and large arteries, which mostly occurs after the age of 50 and involves one side of the body.
We present a 40-year-old male patient with simultaneous bilateral temporal arteritis along with a headache, mild fever, palpation of temporal arteries and anemia who responded to 1 mg/kg oral daily prednisone for three months. This patient was referred to the Pars Hospital in Tehran, Iran on March 2016.
Temporal arteritis should be kept in mind as an important curable differential diagnosis, not only in ages above 50, but also in lower ages and should be evaluated in both sides.
