Percutaneous CT-guided sacroiliac joint sampling for infection: aspiration, biopsy, and technique

Abstract

Objective: To elucidate the management algorithm for sacroiliac joint sampling by percutaneous CT-guided sacroiliac joint sampling for suspected infection patients. Materials and Methods: All CT-guided sacroiliac joint sampling procedures for suspected infection were reviewed for sampling type (aspiration lavage aspiration, biopsy), microbiology results, and clinical and imaging follow-up. The gold standard was pathology. If pathology was not available, then positive blood culture with same organism as SIJ sampling, imaging and clinical follow-up, or clinical follow-up only were used. Anterior and posterior joint distention was evaluated by MRI within seven days of the procedure.
