MRI诊断骨软骨瘤恶变的价值

目的评价MRI诊断骨软骨瘤恶变的价值，探讨该疾病的影像学检查技术路线。方法从5例经手术病理证实为恶变者，回顾性观察其MRI检查表现，并与临床、X线作比对。结果X线能确定1例，怀疑1例；MRI扫描能确定4例，怀疑1例。结论MRI对于诊断此疾病有良好的价值，远远高于临床和X线的判定。X线检查可作为筛查或复查的检查手段。青春期后，临床表现为疼痛、骨软骨瘤进行性增大、骨软骨瘤邻近出见表皮溃破或静脉曲张、体检发现肿块固定且边缘不规则的患者，应及时行MRI检查。如MR!检查仅发现骨软骨瘤钙化灶内有部分为软组织替代，应注意恶变可能。

Value of MRI in the Diagnosis of Malignant Osteochondroma

Objective To Evaluate the value of MRI on diagnosis of canceration osteochondroma and to investigate the imaging technique line of the disease. Methods 5 cases of osteochondroma proved to be canceration were reviewed. The investigate manifestation of MRI, its clinical date and X ray were compared. Results 1 final diagnosis was made by X ray,1 cases was in doubt.4 cases diagnose by MRI, 1 cases was in doubt. Conclusion MRI has greater value for the diagnosis of canceration osteochondroma than X ray and clinical date. The osteochondroma that take place after adolescence, the clinical manifestation is pain, augmentation incessantly, osteochondroma adjacent out see skin dyke break or varicose veins, physical examination found that the osteochondroma fixed and border irregularity, should receive MRI check. Such as MR1 found only soft tissue instead of part of osteochondroma calcification, we should pay attention to that the osteochondroma may be canceration.
