目的：研究髂骨恶性肿瘤的特点及影像表现，提高髂骨肿瘤的影像诊断及鉴别水平。方法回顾性分析33例手术病理或活检证实的髂骨肿瘤及肿瘤样病变的CT表现，分析肿瘤的破坏方式，范围，内部结构，软组织肿块大小。结果(1)髂骨恶性肿瘤病理类型多样，骨髓来源的占大部分，大多数CT表现为溶骨性骨质破坏，盆腔内形成较大的软组织肿块，恶性程度高者易侵犯关节。(2)良性肿瘤和肿瘤样病变多数以膨胀性破坏为主，边界清楚、硬化，无软组织肿块。骨软骨瘤和骨纤维结构不良有其特征性的影像表现。结论髂骨恶性肿瘤的影像表现有其特点，经过仔细观察及综合分析，大部分可定性诊断。

Objective To study the CT feature and imaging finding of malignant iliac tumor, and improve the differential diagnosis of iliac tumor. Methods The imaging features of 33 cases of iliac tumor and tumor-like lesions, proved by pathology, were analyzed retrospectively. The mode of bone destruction, tumor margin, structure of lesion, and the size of soft tissue tumor were analyzed. Results (1) iliac malignant tumors had diverse types of pathology. Bone marrow-derived accounted for the most part, the majority of which showed osteolytic bone destruction and the formation of large soft tissue mass in the pelvis, The higher the degree of malignancy tend to invade the joints. (2) The mode of bone destruction of benign tumors and tumor-like lesions was expansion with clear boundary and hardening without significant soft tissue tumor, While osteochondroma and fibrous dysplasia had its characteristic imaging findings. Conclusion The imaging findings of iliac malignant tumors have their own characteristics, observation and comprehensive analysis will help to get the accurate diagnosis.
