The findings of MR images are compatible with osteoid osteoma.
When an osteoid osteoma is located in the juxtaarticular portion of the proximal femur within the confines of the joint capsule, the clinical presentation can be atypical and mimic symptoms of synovial inflammation. Therefore, osteoid osteoma should be considered early in the workup of the patient with symptoms of hip pain, limp, or pain referred to the knee.3
