Abstract

Objective To improve the diagnostic rate of primary synovial osteochondromatosis by analyzing the imaging features. Methods Analyze 46 cases of primary synovial osteochondromatosis which confirmed by surgery and pathology retrospectively. All 46 cases were undergone X-ray examination, of which 28 cases underwent CT examination and 12 cases underwent MRI examination. Results X-ray plain film showed multiple sizes and numbers of free bodies and dangling bodies. Spiral CT plain scan can clearly find the smaller free body, thickening of the synovial fluid and joint effusion in the joint and synovial bursa. Conclusion X-ray plain film and CT can clearly show the calcification or ossification of the cartilage nodules and have important value in the diagnosis of Milgram stage II and III synovial osteochondromatosis. MRI is able to show cartilage tumor nodules without calcification or ossification in Milgram I clearly, which is expected to make a correct diagnosis. Therefore imaging plays a very important role in the diagnosis of this disease.
