title: Infectious sacroiliitis caused by Staphylococcus aureus following acupuncture: a case report.
abstract: Determination of the origin of infectious sacroiliitis (ISI), a rare form of septic arthritis, is often time consuming and clinically difficult owing to its various presentations, which include joint, skin and urinary tract infections. This report describes the diagnosis, determination of infectious origin and treatment of a case of ISI attributed to the use of acupuncture for the treatment of lower back pain. We report on a 61-year-old man who developed right hip pain and fever 3 days after undergoing acupuncture over the right buttock region for the treatment of lower back pain. Blood culture showed infection with methicillin-susceptible Staphylococcus aureus and MRI disclosed the presence of an inflamed area over the right iliac bone and the right portion of the sacrum. The patient was cured after a 4-week course of antimicrobial treatment. Clinicians should take a history of acupuncture use when evaluating patients presenting with fever of unknown origin and/or bacteraemia and consider the possibility of ISI when evaluating patients with hip pain and infectious signs after acupuncture or other possible causes of infection. This indicates the importance of performing clinically clean procedures to prevent septic complications when treating patients with acupuncture.
