X线平片、CT和MRI诊断滑膜骨软骨瘤病

Plain X-ray radiography,CT and MRI diagnosis of synovial osteochondromatosis

目的比较X线、CT和MRI对滑膜骨软骨瘤病的诊断价值。方法回顾性分析20例经手术病理证实的滑膜骨软骨瘤病患者的X线平片(n=18)、CT(n=20)和MRI(n=10)表现。结果 X线平片正确诊断15例,CT正确诊断18例,MRI正确诊断8例。X线平片、CT和MRI均能显示关节周围及关节内形态多样、大小不一、数量不等的游离体;X线平片和CT均可显示游离体的钙化;MRI可显示早期软骨游离体;CT和MRI可发现关节腔积液。结论 X线平片、CT及MRI均能诊断本病,CT和MR检查能发现X线平片不能检出的病灶和征象。

Objective To assess the value of plain X-ray radiography,CT and MRI in the diagnosis of synovial osteochondromatosis.Methods Twenty patients with synovial osteochondromatosis confirmed with surgery and pathology were enrolled.The images of X-rays（n=18）,CT（n=20） and MRI（n=10） were analyzed retrospectively.Results Definite diagnosis was made in 15 patients according to plain X-ray radiography,in 18 patients according to CT findings,while in 8 patients according to MRI manifestations.Plain X-ray radiography,CT and MRI could show loose bodies around/within the involved joints in various shape,size and different amount.Plain X-ray radiography and CT could show calcification of loose bodies.MRI could show early cartilage loose bodies.CT and MRI could display effusion of the involved joints.Conclusion Plain X-ray radiography,CT and MRI are able to diagnose synovial osteochondromatosis.CT and MRI can depict lesions and characteristics that impossible for X-ray radiography.
