206 cases of chondrosarcoma including central type 159 cases and peripheral type 47 all proved by surgery and pathology were analysed. The important aggressive X-ray signs of central (primary) chondrosarcoma include: Infiltrating, notching and scalloping of the endosteal cortical surface; irregular and ill-defined margin between tumor and bone, transition zone widened or 'moth-eaten' in appearance; soft tissue tumor mass may grow eccentrically or concentrically around the bone; various patterns of calcification within the tumor and localized laminated periosteal reaction. The radiologic features of the secondary peripheral chondrosarcoma are: fuzzy and indistinct surface in the region of the cartilaginous cap which becomes irregular and thickened (more than 1 cm); formation of a soft tissue mass containing faint flocculent or ring-like calcifications; the "bursting" and scattering of old calcifications in the depth of the cartilage cap and destruction of adjacent bone.
对206例经手术及病理证实的软骨肉瘤进行分析，其中中央型159例，周围型47例。中央型（原发性）软骨肉瘤重要的侵袭性X线表现包括：骨内膜皮质表面的浸润、切迹和扇贝样改变；肿瘤与骨质之间边界不规则且不清，过渡带增宽或呈“虫蚀样”外观；软组织肿块可围绕骨质偏心性或同心性生长；肿瘤内各种钙化模式及局限性分层状骨膜反应。继发性周围型软骨肉瘤的放射学特征为：软骨帽区域表面模糊不清，变得不规则且增厚（超过1cm）；形成含有模糊絮状或环状钙化的软组织肿块；软骨帽深部陈旧钙化的“爆裂”和散在，以及相邻骨质破坏。
