      ]. Iliopsoas abscess (IPA) is an uncommon infective clinical condition, often with nonspecific signs and symptoms. IPA is classified based on its origin, with primary IPA thought to be triggered by an unrecognized staphylococcal bacteremia, and secondary IPA caused by an underlying condition or disease, or spread of infection subsequent to surgery [

      ]. Delays in diagnosis may lead to increased morbidity and mortality. Modern imaging techniques such as ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) are often used to confirm IPA diagnosis. There is no uniform treatment strategy for IPA, however therapy usually consists of broad-spectrum antibiotics, often combined with percutaneous or surgical drainage [
