毛细血管扩张型骨肉瘤影像与病理对照分析

目的　探讨毛细血管扩张型骨肉瘤影像与病理表现特征。方法　分析 12例毛细血管扩张型骨肉瘤临床、影像及病理资料。结果　临床特征为肿瘤好发于长骨干骺端 ,下肢多见 ,少有血清碱性磷酸酶增高。X线、CT特征为溶骨性与膨胀性骨破坏 ;肿瘤破坏区和软组织肿块内多发小囊变和液 -液平面 ;皮质变薄 ,多发筛孔样破坏 ;骨膜反应及放射状骨针较常见。病理组织学特征为典型骨肉瘤肿瘤细胞和多发血窦及“彩带样”结构。结论　毛细血管扩张型骨肉瘤具有一定的临床、影像及组织学特征

The Comparative Study on Imaging and Pathology of the Telangiectatic Osteosarcoma

Objective To explore the imaging and pathological characteristics of the telangiectatic osteosarcoma.Methods The clinical,imaging and pathological data of telangiectatic osteosareoma in 12 cases were analysed.Results The tumors often located at the diaphysialepiphysial of the os longum and most of them were occured at the lower limb,increasing of the alkaline phosphatase(AKP) was rare.X-ray and CT character istics were osteoclastic and expensive bony destruction;there were multiple small cystic formation and fluid-fluid level in the destructive region and soft masess;the cortex of the bone became thinner with multiple sieve type destruction;the periosteal reaction and radial bone spicule were often seen.Pathological characteristics were of typical tumor cell of the osteosarcoma,mutliple sinus of the blood and "color bland shape" component.Conclusion The telangiectatic osteosarcoma has certain specific clinical,imaging and histologyical characteristics.
