Özet
Variable clinical and radiological findings for intra-articular osteoid osteoma (OO) of the hip joint make its diagnosis difficult. Because radiographs commonly do not identify the nidus, MR imaging becomes the second line of study. However, because the appearance varies, findings on MR images can be confusing. We found "collar type osteophyte" of the femur i.e. an osteophyte rim around the femoral neck, to be a conspicuous finding of intra-articular OO. Here, this feature will be emphasized and intra-articular OOs will be discussed, with a review of the literature. © 2013 Japan Radiological Society.
