Glenohumeral Joint Sepsis After Magnetic Resonance Imaging Arthrogram

A 65-year-old patient presented with right shoulder pain that had increased in severity over the preceding 2 days. The pain began after the patient had a gadolinium arthrogram for magnetic resonance imaging for rotator cuff evaluation. Examination and laboratory test findings were consistent with a septic glenohumeral joint and emergent arthroscopic irrigation and debridement were performed. Streptococcus sanguinis was isolated from the intraoperative culture, and the infection resolved after a course of antibiotics.
