ABSTRACT

ObjectiveTo assess the value of plain X-ray radiography,CT and MRI in the diagnosis of synovial oateochondromatosis.MethodsTwenty 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.ResultsDefinite 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.ConclusionPlain 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.
