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.
腰大肌脓肿可分为原发性和继发性。原发性腰大肌脓肿无法确定其他感染部位。该肌肉发生脓肿是因其血管丰富，金黄色葡萄球菌是最常见的感染病原体。治疗需要使用适当的抗生素，以及对脓肿进行手术或经皮引流。经皮引流的侵入性小得多，对获得性免疫缺陷综合征患者风险低，甚至对多房性脓肿引流也有效。作者报告了1例获得性人类免疫缺陷综合征患者发生原发性腰大肌脓肿的罕见病例，该患者通过腰小三角在腰下部区域出现肿块并伴有发热。经皮引流联合全身抗生素治疗取得成功。
