title: Primary psoas abscess in a patient affected by acquired immunodeficiency syndrome: a rare case according to the reviewed literature.
abstract: Abscesses of the psoas muscle can be divided into primary and secondary. In the primary ones, it is not possible to identify any further infected site. The localization to this muscle is due to its rich vascularization and Staphylococcus aureus is the most frequent aetiological agent of the infection. Treatment requires the use of appropriate antibiotics, as well as surgical or percutaneous drainage of the abscess. The percutaneous drainage is much less invasive and a low risk in the patients with acquired immunodeficiency syndrome, and is effective for draining even multiloculated abscess. The authors present a rare case of primary psoas abscess in patient affected by acquired human immunodeficiency syndrome, showing a mass in the inferior lumbar region through the lumbar triangle of Petit and fever. Treatment consisting in percutaneous drainage combined with systemic antibiotic administration was successful.
