The authors reviewed the anatomy of the iliopsoas compartment and a spectrum of unusual lesions affecting structures in this compartment, with emphasis on the role of computed tomography (CT). Lesions in the iliopsoas compartment are caused by acute infection, tumor, or hemorrhage. The knowledge of detailed clinical data can help improve the diagnostic accuracy, particularly with regard to primary iliopsoas lesions. CT is useful for delineating the source of secondary iliopsoas lesions, guiding biopsy, and performing follow-up of treated lesions. Nonenhanced CT can help detect fresh hemorrhage, fat-containing tumor, and calcification, whereas contrast material enhanced CT optimizes imaging of infection, tumor, and aneurysm.
作者回顾了髂腰肌间隙的解剖结构以及一系列影响该间隙结构的罕见病变，并重点介绍了计算机断层扫描（CT）的作用。髂腰肌间隙的病变由急性感染、肿瘤或出血引起。了解详细的临床数据有助于提高诊断准确性，尤其是对于原发性髂腰肌病变。CT有助于确定继发性髂腰肌病变的来源、指导活检以及对治疗后的病变进行随访。非增强CT有助于检测新鲜出血、含脂肪肿瘤和钙化，而对比剂增强CT则可优化对感染、肿瘤和动脉瘤的成像。
