Abstract

We report a case of primary infant iliopsoas abscess. A 3-month-old male infant was brought to our hospital because of groin mass with redness. Blood analysis results indicated inflammation, and abdominal-pelvic computed tomography showed an abscess in the right iliopsoas muscle. After admission, intravenous infusion of antibiotics was started, but antibiotic therapy alone was insufficient. We performed emergency percutaneous abscess drainage with a small incision. Fifteen days after the operation, the patient was discharged from our hospital. Culture of abscess fluid was positive for methicillin-sensitive Staphylococcus aureus. Blood culture on admission was negative, and pelvic magnetic resonance imaging (MRI) on the second day after admission did not show coxitis, spondylitis or iliosacral arthritis. The etiology of iliopsoas abscess in this patient was unknown. The major presenting symptom of infant iliopsoas abscess is groin swelling. Computed tomography (CT) and MRI are necessary for the differential diagnosis of infant groin mass with redness.
