滑膜软骨瘤病X线平片诊断分析

Diagnostic analysis of radiography for synovial osteochondromatosis

目的:提高滑膜软骨瘤病诊断水平。方法:对1990年～2002年间经病理证实的17例滑膜软骨瘤病进行回顾性分析。结果:X线正确诊断14例,单侧膝关节为最易受累关节。X线片及术中均见游离体大小不等、形态多样,数目从1枚至数十枚。结论:关节游离体钙化是影像诊断本病的主要依据,普通平片是确诊本病的最简单方法。

Objective To improve the diagnosis accuracy for synovial osteochondromatosis(OS).Method15cases of OS.veri-fied by pathology were reviewed from1990to2002.Results Radiograph confirmed12cases.The unilateral knee joint was mostly affected.The loose bodies,which varied from1to several dozens in number,presented variant sizes and shapes in image and op-era tion.Conclusion Calcification of loose bodies within joint is the basis of imaging diagnosis.X-ray film is the simplest means to di agnose OS.
