目的 探讨长骨皮质型骨转移瘤的X线诊断。材料与方法 回顾性分析 7例经病理或随访证实的长骨皮质型转移瘤的X线表现 ,男 5例 ,女 2例。年龄 5 0～ 70岁 ,平均 6 2岁。结果 6例表现为“挖凿”样皮质缺损 ,1例呈边缘不清的虫蚀样皮质破坏。3例伴有明显骨膜反应 ,其中 1例有Codman三角。结论 长骨皮质型转移瘤的典型X线表现是“挖凿”样皮质破坏 ,可伴有明显骨膜反应 ,在诊断时需结合患者的年龄和病史以与原发性恶性骨肿瘤鉴别
Objective To investigate the X-ray diagnosis of long bone cortical bone metastases. Materials and Methods Retrospective analysis of 7 cases of long cortical bone metastases confirmed by pathology or follow-up X-ray findings, 5 males and 2 females. Aged 50 to 70 years old, average 6 2 years old. Results 6 cases showed as “digging” like cortical defect, 1 case of the edge of the worm-like cortical destruction. 3 cases with significant periosteal reaction, including 1 case of Codman’s triangle. Conclusion The typical X-ray findings of long-cortical bone metastases are “digging” like cortical destruction and may be accompanied by obvious periosteal reaction. The diagnosis should be based on the patient’s age and medical history to distinguish them from primary malignant bone tumors
