Methicillin Resistant Staphylococcus Aureus Sacroiliac Joint Septic Arthritis in an Adult Patient Treated with Daptomycin

Abstract. Sacroiliac joint septic arthritis is a rare disease entity representing 1-2% of all cases of septic arthritis. Establishment of the diagnosis is often challenging given the non-specific presenting features and the potential cross-over with other pathologies. We report the case of a 50 year old gentleman who suffers with psoriasis and presented with sacroiliac joint septic arthritis complicated by Methicillin Resistant Staphylococcus Aureus (MRSA) bacteraemia and an iliopsoas abscess. This was successfully treated conservatively with a course of the novel antibiotic Daptomycin.
