|Unilateral Acute Sacroiliitis - Think Infection, No Injection !|
Acute unilateral sacroiliitis should always raise suspicious for the possibility of septic arthritis particularly solitary involvement of the ligamentous portion as well as in the presence of adjacent soft tissue oedema or juxta-articular collections.
Radiological suspicion should dictate further management with image-guided aspiration or serological testing (in cases of tuberculosis or brucellosis).
Any corticosteroid intra-articular injection should be avoided until this suspicion is clearly refuted.
