【摘要】：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)cm~2,盆外为(22.85±15.70)cm~2。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。
[Abstract]:Objective to compare the CT and MRI features of primary iliac osteosarcoma and Ewing's sarcoma. Methods the clinical and imaging data of 13 patients with iliac osteosarcoma and 10 patients with Ewing's sarcoma were retrospectively analyzed. The average age of osteosarcoma was 16.2 卤8.2 years old. 7 cases of mixed osteosarcoma and 3 cases of osteogenic bone destruction were found. In 2 large cases of osteosarcoma, there were multiple cystic foci and liquid-liquid level. 8 cases of mixed bone destruction, 2 cases of osteolytic bone destruction, 7 cases of lamellar periosteal reaction, and 7 cases of reactive new bone were found in Ewing's sarcoma. Most of them were flaky. The maximum area of Ewing's sarcoma in the pelvis was 38.55 卤28.74 cm ~ (-2), while that outside the pelvis was 22.85 卤15.70 cm ~ (-1). Conclusion the onset age of iliac osteosarcoma is larger than that of Ewing's. The liquid-liquid level in osteoblasts and soft tissue masses suggests osteosarcoma, and lamellar periosteal reaction and soft tissue masses that tend to grow into pelvis are more common in Ewing's sarcoma.
