Abstract:
Objective To probe the diagnostic value of MRI in synovial hemangioma of the knee.Methods Seven patients(2 male,5 female,age ranged from 8 to 58 years with mean age 25.1 years) selected from 2025 cases with MRI examination of knee,which were proved to be intra-articular hemangiomas histologically or clinically.All of the patients had plain film before MRI examination.MR findings of synovial hemangioma of knee were analysed ultrasound.Results Four hemangiomas occurred in infrapatellar bursa,others 3 cases in both infrapatellar and suprapatellar bursa were involved.MR signal intensity of hemangiomas appeared three types:(1)nodular hypointensity on both T_1WI and T_2WI in 2 cases;(2)iso-hypointensity on T_1WI and hyper-hypointensity on T_2WI in 2 cases;(3)hypointensity mixed with isontensity on T_1WI and nodular of linear mixedintensity on T_2WI in 3 cases.The difference of synovial hemangioma of knee in histologic elements,the MR findings were different.Conclusion MRI features of synovial hemangioma are correlated with pathology histologic elements.
