The iliopsoas compartment is an extraperitoneal space that contains the greater psoas, smaller psoas, and iliac muscles. Many pathologic processes may involve the iliopsoas compartment, including inflammatory, hemorrhagic, and neoplastic conditions. Psoas muscle infection is usually due to direct extension from contiguous structures. With the decreasing incidence of tuberculosis, the majority of psoas abscesses now encountered have a pyogenic origin. Hemorrhage into the psoas muscle can be spontaneous or secondary to various conditions. Neoplastic involvement of the psoas muscle is usually due to contiguous spread and is rarely primary. With the refinement of imaging modalities, there has been increased recognition of diseases that involve the iliopsoas compartment. Although these conditions may look similar radiologically, they can be correctly diagnosed by combining the radiologic findings with the clinical history. Biopsy is effective in diagnosis of such conditions; aspiration and drainage are effective in both diagnosis and therapy.
髂腰肌间隙是一个腹膜外间隙，包含腰大肌、腰小肌和髂肌。许多病理过程可能累及髂腰肌间隙，包括炎症、出血和肿瘤性疾病。腰大肌感染通常是由于邻近结构的直接蔓延所致。随着结核病发病率的下降，目前遇到的大多数腰大肌脓肿都起源于化脓性感染。腰大肌出血可为自发性或继发于各种情况。腰大肌的肿瘤累及通常是由于邻近蔓延，很少是原发性的。随着成像方式的不断完善，对累及髂腰肌间隙的疾病的认识有所增加。尽管这些疾病在影像学上可能看起来相似，但通过将影像学表现与临床病史相结合可以正确诊断。活检对这些疾病的诊断有效；穿刺抽吸和引流对诊断和治疗均有效。
