中文摘要:
      目的 探讨骨肉瘤不同亚型的临床和影像学表现,提高对骨肉瘤亚型的认识。方法 回顾分析经病理证实的6种 亚型11例骨肉瘤的临床及影像学表现。结果 本组11例患者中毛细血管扩张型3例,表现为膨胀性、溶骨性骨质破坏,病灶内多 发囊变,呈分房状,其内常见液-液平。皮质旁型2例,表现为骨表面的高密度肿块伴瘤骨形成。骨膜型2例,表现为骨表面密度 不均的肿块,可见放射状分布的肿瘤骨,骨膜反应明显,髓腔未受累。小细胞型2例,呈溶骨性骨质破坏,骨皮质虫噬状破坏,骨膜 反应及软组织肿块形成。颌骨型1例,表现为以颌骨为中心的软组织肿块,伴肿瘤骨形成。多中心型1例,表现为多发病灶,主病 灶呈典型骨肉瘤表现,周围伴多发子灶形成。结论 骨肉瘤亚型具有一定的临床和影像特点,有助于诊断。
