Abstract

We describe the clinical course of a 60-year old male admitted with Staphylococcus aureus bacteremia and back-pain. The patient was suspected of having spondylitis and treated as such with antibiotics; however, both fluorine-18 fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography and magnetic resonance imaging (MRI) with iv contrast showed significant inflammation of muscles and subcutaneous soft tissue in relation to the patients back and left shoulder, but no signs of the working diagnosis of spondylitis. The unusual location of the infection was not explained until a few days prior to being discharged when the patient reported visits to a local physiotherapist where he would have acupuncture performed for non-specific back pain. His last acupunctural procedure had been performed 6 days prior to admission. This case is, to our knowledge, the first to show muscular inflammation on both 18-F-FDG PET/CT and MRI following acupuncture due to S. aureus. This case highlights the need for clinicians to search for alternative explanations when imaging does not support the diagnosis. View Full-Text
