髋部骨髓水肿综合征的MRI诊断

Objective To investigate the imaging diagnosis of bone marrow edema syndrome of the hip. Methods The imagingdata of 13 cases9 males and 4 femalesof bone marrow edema syndrome were collected. All patients were followed-up for 3to 6 months.13 patients underwent MRI scanning and 5 patients underwent X-ray examination. Results Thirteen cases ofbone marrow edema syndrome of the hip, right hip in 8 cases, left hip in 5 cases. The bone marrow edema pattern involved thefemoral head and femoral neck in 10 hips. The bone marrow edema involved thefemoral head and femoral neck and femoraltrochanteric in 3 cases. The MRimages demonstrated low signal intensity in all 13 cases on T1WI and normal signal intensityin1 case on T2WI.moderateor high signal intensity in 12 cases on T2WI and high signal on T2fat suppressed in all 13 cases. Asmall joint effusion was observed in 4 cases on T2WI. X-ray manifestations: femoral head and femoral neck bone densitydecrease in 5 cases. The femoral head shape and bone cortex were normal in all 13 cases. Conclusion Familiar with theimaging findings of bone marrow edema syndrome of the hip canimprove the correct diagnosis.
