A clinical case of orchitis with brucellosis etiology is presented. Testicular symptomatology appeared from the beginning of the brucellosis's general clinical picture. It envolved painfully and increased the testicular size, with no mictional symptoms, expanding progressively in spite of specific brucellosis therapy given from the beginning, towards formation of an intratesticular abscess which required orchiectomy, a way of progression we have not found in the related literature. The main differential diagnosis must be done with tuberculosis orchitis. Since our country had the largest incidence of brucellosis in Europe, and it is possible that in many cases a orchiepididymarial condition can become apparent in the initial phases, this is an etiology that should be taken into account among specific orchiepididymitis.
