In this report, we described a diabetic patient with nephrotic syndrome, who suffered from Staphylococcus aureus pyomyositis without antecedent predisposing event. The 45-year-old man was admitted for legs swelling and fever. Magnetic resonance images revealed homogeneous enhancement of adductor magnus muscle and adjacent tissue. There is a hypointense region within the adductor for magnus muscle, which is compatible with abscess. Pus-like material from both needle aspiration and surgical debridement yielded methicillin-sensitive Staphylococcus aureus (MSSA). The patient improved after the operation and antibiotic treatment. Pyomyositis rarely occurred within adductor muscles. The possible mechanisms leading to this rare complication in diabetic patients were also discussed.[SDGs]SDG3antibiotic agent; meticillin; abscess; adult; antibiotic sensitivity; article; case report; comorbidity; contrast enhancement; debridement; diabetes mellitus; disease predisposition; fever; hospital admission; human; leg edema; leg muscle; male; needle biopsy; nephrotic syndrome; nuclear magnetic resonance imaging; pyomyositis; skeletal muscle; Staphylococcus aureusjournal article2-s2.0-0036287510
