X-ray DIAGNOSIS OF EXTRASKELETAL (SOFT TISSUE) CHONDROSARCOMA (A REPORT OF 8 CASES)

Eight cases of surgically and pathologically verified extraskeletal (soft tissue) chondrosarcoma were analyzed with regard to clinical and X-ray features. The cardinal clinical aspects of this series are: presence of a local soft tissue mass; gradual enlargement of the mass accompanied by increasing pain. The X-ray signs were summarized as follows: formation of a soft tissue mass; various forms of calcifications concentrated in the central area of the tumor; in some instances, presence of a saucer-like defect on the cortical surface of neighbouring bone and periosteal proliferation with mound-like new bone on both sides as well as bending deformity of the affected bone. The incidence and sites of predilection, the main X-ray findings, radiological diagnosis and differential diagnosis of the tumor were discussed. The Roentgen features of synovial chondrosarcoma of the knee joint were especially analyzed.

老年性骨质疏松在脊椎骨的放射学表现

对1120例老年性骨质疏松的胸椎(368例)、腰椎(752例)X线片进行了分析。结果表明,老年性骨质疏松在脊椎骨的放射学改变包括①普遍性骨密度减低;②骨小梁细、疏,首先是水平小梁的吸收、减少,以至消失,严重者仅留有粗、疏的垂直小梁;③椎体软骨下骨板和皮质骨的变淡、减薄;④椎体形态的改变,如椎体双凹变形或“鱼椎”,楔形变和椎体压缩变扁或“单饼椎”等。
