We report a 54-year-old female with abrupt onset of right hip pain. Physical examination was normal exept for tenderness and limitation of ROM of the affected joint. The conventional radiographs showed only osteopenia in the proximal femur. Bone scintigrams showed diffuse increased uptake in the resion of the affected joint. MRI demonstrated diffuse low intensity on T1-weighted images in the proximal femur with matching area of increased intensity on T2-weighted images. Diagnosis of transient osteoporosis of the hip was made based on clinical and radiographic findings. The patient was treated conservatively. Six months after the onset, her right hip pain disappeared and the examination by radiographs, bone scintigrams, and MRI turned out to be almost normal. No symptoms of any recurrence was recognised.
We believe that bone scintigram and MRI are very helpful in the diagnosis of transient osteoporosis of the hip.
