Bilateral psoas abscesses caused by methicillin-resistant Staphylococcus aureus (MRSA) after posterolateral fusion of the lumbar spine.
Psoas abscess following spine surgery is a rare condition that can be overlooked or delayed as a result of its vague clinical manifestations. Gone unchecked, it can lead to severe morbidity and even death. We present a 71-year-old female patient who developed bilateral psoas abscess immediately following L2 through S1 posterior instrumented fusion. The patient underwent CT-guided percutaneous drainage of the bilateral psoas abscess and blood cultures revealed methicillin-resistant Staphylococcus aureus (MRSA) sensitive to vancomycin. Following surgical re-exploration, debridement and removal of part of the instrumentation, the patient received antibiotic treatment for 12 weeks and at 1-year follow-up the patient continues asymptomatic.
