[Granulomatous nephropathy of tuberculous origin revealed by prolonged fever (author's transl)].

In a 66-year-old female patient with a past history of tuberculosis, prolonged fever at 38 degrees C accompanied by a strong increase in ESR ultimately led to the diagnosis of renal cyst. Biopsies of renal tissue and of lymph nodes taken during surgery showed renal granulomatosis without caseum. Despite negative bacterial findings and anergy to tuberculin, an anti-tuberculous treatment was administered and the patient recovered.
