摘要： 目的分析骨盆骨肉瘤CT及磁共振成像(MRI)表现。方法回顾分析2013 年1 月~2015 年12 月病理证实的15 例骨盆骨肉瘤的CT及MRI表现，总结分析其影像学表现、特征及影像学鉴别诊断。结果15 例患者中，男性10 例，女性5 例；年龄中位数27.0 岁。11 例累及髂骨；病灶骨质破坏类型表现为混合型11 例，溶骨型2 例，硬化型2 例；5 例伴放射状骨膜反应；病灶内见肿瘤骨8 例。骨旁软组织肿块13 例。MRI显示全部病例病灶内强化；2 例硬化型骨内病灶CT未显示明显强化。结论骨盆骨肉瘤发病影像学典型表现为混合型骨质破坏，伴放射状骨膜反应及软组织肿块，病灶内显示瘤骨。

Abstract: Objective To analyze the CT and magnetic resonance imaging (MRI) manifestations of the pelvic osteosarcoma. Methods The CT and MRI manifestations of 15 cases with pelvic osteosarcoma from January, 2013 to December, 2015 proved by histology were retrospectively analyzed. Results There were 10 males and 5 females in them. The median age was 27.0 years. Ilium was involved in 11 cases. A mixed lytic/sclerotic pattern of bone destruction was found in 11 cases, and the sclerotic type in 2 cases, the osteolytic type in 2 cases. Radial periosteal reaction was found in 5 cases and immature bone formation in 8 cases. Soft tissue masses were seen in 13 cases. MRI showed enhancement in 15 cases and the CT showed no enhancement in 2 cases with sclerotic type. Conclusion The typical imaging manifestations of pelvic osteosarcomainclude mixed lytic/sclerotic appearance, radial periosteal reaction, soft tissue masses and immature bone formation.
