多灶性骨肉瘤的影像学诊断分析

Analysis of imaging diagnosis in multifocal osteosarcoma

目的:分析15例多灶性骨肉瘤的影像学和临床诊断特点。方法:对15例经手术后病理证实的多灶性骨肉瘤的X线、CT、MRI、SPECT影像学资料和临床诊断特点进行回顾性分析评估。结果:多灶性骨肉瘤的发病率为6.85%,SPECT对多灶性骨肉瘤的显示率为92.31%。同时性多灶性骨肉瘤多发于青少年,异时性多灶性多发于成年人。结论:多灶性骨肉瘤的影像学特点主要呈成骨性改变,CT、MRI、SPECT扩展和加深了对多灶性骨肉瘤的认识,为临床诊断提供了全面、准确的影像学资料。

Objective: To analyze the features of imaging and clinical diagnosis in 15 cases of multifocal osteosarcoma. Methods: The features of clinical diagnosis and imaging of X-ray, CT, MRI and SPECT in 15 cases of multifocal osteosarcoma were analyzed retrospectively and were confirmed by pathology after operation. Results: The incidence rate of multifocal osteosarcoma was 6.85%, the display rate of multifocal osteosarcoma was 92.31% with SPECT. Synchronous multifocal osteosarcoma occurred in teenagers, asynchronism multifocal osteosarcoma occurred in adult. Conclusion: The features of imaging in multifocal osteosarcoma were showed osteoblastic-type mostly. CT, MRI and SPECT expanded and deepened our understanding about the signs of multifocal osteosarcoma, and provided much more accurate and comprehensive imaging informations for clinical diagnosis.
