Sacroiliites infectieuses non tuberculeuses. Manifestations cliniques et intérêt diagnostique de la ponction-biopsie sacroiliaque au trocart chez 18 patients

We report a series of 18 patients with non tuberculous pyogenic sacroiliitis. All patients presented with unilateral buttock pain associated with fever. Pelvic radiographs, CT and bone scan were diagnostic of sacroiliac joint disorder. We emphasize the usefulness of the sacroiliac joint needle biopsy which permitted the bacteriological diagnosis in 13 out of 18 patients.
