Primary Iliopsoas Abscess due to Staphylococcus aureus: 3 cases reports

ABSTRACT

Primary iliopsoas abscess, without a causative infection focus, is a very rare kind of retroperitoneal abscess. Immunocompromised patient, such as elderly patients, diabetics and patients with chronic disease, are susceptible to this kind of infection. Because early diagnosis of priiliopsoas abscess is usually delayed due to nonspecific clinical presentation, proper treatment is also delayed which causes high mortality and morbidity. Recently we experienced three cases of primary iliopsoas abscess due to Staphylococcus aureus. Diagnosis of these cases was belatedly confirmed by using a abdominal-pelvic computerized tomography (CT) scan. Open surgical drainage via an extraperitoneal approach and administration of appropriate systemic antibiotics were required to save these patients. Based on a review of the literature, we evaluated the diagnosis and treatment of primary iliopsoas abscess.
