Coxofemoral Arthritis Caused by Mycobacterium Bovis after Bacillus Calmette-Guérin Therapy

Abstract

normocytic normochromic anemia with a 10 g/dl Hb, normal leukocyte count, 30 mm erythrocyte sedimentation rate (ESR) in the first hour and a 25 mg/l CRP. Renal and hepatic biological assessments were normal. The tuberculin skin test was positive at 10 mm and HIV status was negative. Right hip and pelvis radiographs showed a narrowing coxo-femoral joint space with demineralization and geodes of the femoral head (Figure 1).Pelvic CT scan showed an asymmetric basin, with the loss of the right femoral head sphericity and ankylosis of the coxo-femoral space with infiltration of the periarticular soft tissue (Figure 2). The search for germs in the joint fluid was negative on direct examination and the histological study of the synovial performed after a CT guided biopsy showed an epitheloid giant cell granuloma with caseous necrosis suggestive of coxo-femoral tuberculosis (Figure 3). Chest X-ray showed no abnormality and Koch bacillus research
