Abstract:
Objective To investigate the image characteristics of Synovial Sarcoma, and improve the diagnostic accuracy. Methods The clinical materials and image findings of synovial sarcomas proved by pathology and were retrospectively analyzed in 13 cases.Results ①Most synovial sarcomas located in close proximity to joints, especially large joints of lower limbs . ②The mass diameter was usually more than 5cm ,and most masses presented moderate density, and some with calcification inside it on X-ray films. ③Most masses density was not homogeneous and lower than that of the muscle on CT, the demarcation was clear or not. ④On T2WI /STIR of MRI, most tumours presented slightly hyperintense "cobble" nodules , with hypointense septa among the nodules. After contrast, the nodules were unenhanced or enhanced slightly,the septa were markedly enhanced. Conclusion Some image features of synovial sarcoma ,especially on MRI, are helpful for the diagnosis of it.
