| 目的 对比分析髂骨原发骨肉瘤和尤文肉瘤的X线、CT和MRI特征，探讨其临床特点。方法 回顾性分析13例髂骨骨肉瘤患者及10例尤文肉瘤患者的临床和影像学资料。结果 骨肉瘤患者发病年龄12～51岁，平均（26.6±13.5）岁，尤文肉瘤患者发病年龄4～22岁，平均（16.2±8.2）岁。骨肉瘤患者混合型骨质破坏7例、成骨型骨质破坏3例；瘤骨形态多为棉絮状、针状、不规则形，体积较大。2例骨肉瘤内见多囊性灶并液-液平面。尤文肉瘤患者混合性骨质破坏8例，溶骨性骨质破坏2例；层状骨膜反应7例；尤文肉瘤内可见反应性新生骨，多为淡片状。骨盆内尤文肉瘤最大层面面积为（38.55±28.74）cm2，盆外为（22.85±15.70）cm2。结论 髂骨骨肉瘤的发病年龄较尤文肉瘤偏大；大面积瘤骨、单纯成骨性骨质破坏和软组织肿块内出现液-液平面提示骨肉瘤；层状骨膜反应和倾向于向骨盆内生长的软组织肿块多见于尤文肉瘤。 |

| Objective To analyze and compare the imaging findings of primary osteosarcoma (OS) and Ewing's sarcoma (ES) of ilium in X-rays, CT and MRI, and to discuss the clinic features. Methods Imaging and clinical data of 13 patients with iliac OS and 10 patients with ES were retrospectively analyzed. Results OS patients aged from 12 to 51 years old, the average age was (16.2±8.2) years, ES patients aged from 4 to 22 years old, the average age was (26.6±13.5) years. OS patients included 7 cases of mixed bone destruction and 3 cases of sclerosis bone destruction. OS had extensive bone formation like cloudy, radiate or irregular shape. The finding of fluid-fluid levels were also founded in two cases of OS patients. ES showed mixed bone destruction in 8 cases and osteolytic bone destruction in 2 cases. The lamellar periosteal reaction and reactive sclerosis bone were detected in 7 cases of ES. For all of ES, the maximum area of soft tissue mass was (38.55±28.74)cm2 inside of pelvis and (22.85±15.70)cm2 outside of pelvis. Conclusion The age of iliac OS is older than ES. Extensive bone formation, simple sclerosis bone destruction and fluid-fluid levels in soft tissue mass suggests OS. Laminated periosteal reaction and soft tissue masses tend to grow into the pelvis suggests ES. |
