MRI diagnosis and differential diagnosis of transient bone marrow edema syndrome of the hip / 第三军医大学学报

ABSTRACT

Objective To study MR imaging features of transient bone marrow edema syndrome of the hip so as to improve its diagnosis and differential diagnosis.Methods MR images of transient bone marrow edema syndrome of the hip in 13 patients were retrospectively analyzed in combination with literature review.Results The bilateral hips were affected in 4 patients.The single hip was affected in 9 patients,left hip in 6 and right hip in 3.The MR images demonstrated low signal intensity in all 13 patients on T1WI,and normal signal intensity in 2 patients,moderate or high signal intensity in 11 patients on T2WI,and high signal on T2 fat suppressed or STIR images in all 13 patients.The bone marrow edema pattern involved the femoral head and neck in 13 hips,the femoral head and neck and the intertrochanteric region in 4 hips.A small joint effusion was observed in 8 hips on T2WI.The configuration of femoral heads were normal.Conclusion Correct judgement of MRI manifestations of transient bone marrow edema syndrome of the hip can improve its diagnosis and differential diagnosis.
