摘要
目的探讨长骨骨干骨肉瘤的影像诊断及提高其影像诊断水平。方法回顾性分析24例经病理证实的长骨骨干骨肉瘸的X线、MRI表现。24例均行X线平片．其中15例行MRI扫描。结果24例4-13例发生在股骨，5例发生在胫骨，3例发生在腓骨，3例发生在肱骨。13例表现为斑片状、茧蚀样的溶骨性骨质破坏，5例表现为象牙状成骨性骨质破坏．6例表现为混合型骨质破坏；19例可见针状、葱皮状或Codman三角状骨膜反应。结论成骨型骨干骨肉瘤较易诊断，溶骨型骨干骨肉瘤应与Ewing肉瘤、恶性巨细胞瘤等鉴别．X线平片结合磁共振能提高其诊断准确性。
Objective Exploring imaging diagnosis of Osteosarcoma of long bone diaphysis and improve diagnostic capacity. Methods A retrospective analysis was made on plain film and MRI of 24 cases with pathotogically approved Osteasarcoma of long bone diaphysis. All the patients received radiography, MRI was done 15 cases. Results In the 24 cases of Osteosarcoma of long bone diaphysis, there were 13 lesions located in femur, 5 in tibia, 3 in fibula and 3 in humerus. In the24 cases of Osteosarcoma of long bone diaphysis, 13 cases presented as moth - eaten - llke or rotten - wood - like cortical destruction, 5 cases presented as and 6 cases had mixed destruction of bone; 19 cases had needle-like/spiculae or Codman periosteal reaction. Conclusion The osteogenic type is diagnosed easily, hut the asteolytic lesion should be differentiated from Ewing＇s sarcoma, malignant giant cell tumor of bone and so on, Combining with plain film and MRI can improve the diagnosing accuracy of Osteosarcoma of long bone diaphysis.
