Detailed analysis of the roentgen findings in 30 well-documented cases of parosteal osteogenic sarcoma (POS) was made. The supposedly characteristic periosteal lucency (cleavage plane) was found in only 30% of the patients. While most tumors were densely ossified, the radiodensity was uniform in only 27%. The surface of the tumor was usually irregular and a truly smooth surface was seen in only 24%. Four patients underwent arteriography; there was vessel displacement by the tumors but all were avascular. No correlation between the histologic grade of tumor and roentgen signs was found.
对30例记录完整的骨旁骨肉瘤（POS）病例的X线表现进行了详细分析。仅30%的患者发现了所谓典型的骨膜透亮区（劈裂平面）。虽然大多数肿瘤骨化致密，但仅27%的肿瘤密度均匀。肿瘤表面通常不规则，仅24%的肿瘤表面真正光滑。4例患者接受了动脉造影；肿瘤导致血管移位，但所有肿瘤均无血管。未发现肿瘤组织学分级与X线征象之间存在相关性。
