膝关节滑膜软骨瘤的影像学诊断

The Imaging Diagnosis of Knee Synovial Chondroma

目的探索影像学中的X线、CT及MRI在诊断膝关节滑膜软骨瘤中的作用。方法对本院2009年8月至2011年9月经手术病理证实为膝关节滑膜软骨瘤的25例病例进行回顾性分析,25例病例中行X线平片检查的为25例,行CT检查的有20例,行MRI检查的有15例。结果行X线平片检查的25例患者中诊断阳性者19例,行CT检查的20例患者中诊断阳性者为19例,行MRI检查的15例患者中诊断阳性者为12例,检出率分别为76%、95%和80%,但是差异无统计学意义(P>0.05);X线平片检查显示阳性者关节内以及关节周围可见卵圆或圆形的结节状的骨化或钙化影,CT和MRI检查显示阳性者可见骨化或钙化影,但是在清晰度和数量上要优于X线平片检查。结论 X线、CT及MRI均可诊断膝关节滑膜软骨瘤,CT的检出率较高,诊断效果也较好;临床诊断时可将更廉价X线平片检查作为膝关节滑膜软骨瘤患者的首选诊断方法。

Objective To explore the imaging of X-ray,CT and MRI in the diagnosis of knee synovial chondroma.Methods Our hospital pathologically confirmed knee synovial chondroma were retrospectively analyzed 25 cases,25 cases BOC X-ray check of 25 cases,a CT scan on August 2009-Sepetmber 2011 menstrual 20 cases,15 patients underwent MRI.Diagnosis of 19 cases of positive results in 25 patients were examined by X-ray film,20 patients underwent CT examination,diagnosis positive for 19 cases,15 patients underwent MRI diagnosis positive for 12 cases,the detection rates were 76%,95% and 80%,respectively,but the difference was not statistically significant（P 0.05）;X-ray examination showed positive intra-articular and periarticular ossification the visible oval or round nodular or calcification,CT and MRI revealed a positive the visible ossification or calcification,but is superior in clarity and the number of X-ray examination.Conclusion X-ray,CT and MRI can diagnose knee synovial chondroma higher detection rate of CT,the diagnostic results would be better as a knee joint synovial chondroma;clinical diagnosis may be more inexpensive X-ray examination patients preferred diagnostic method.
