Intracapsular osteoid osteoma of the hip

Case contributed by Dr Hector RiveraMelo


Hip pain, unrelated to physical activity.

Patient Data

Age: 10
Gender: Female

Low signal lesion with surrounding marrow edema in the proximal right femur. Also note, large joint effusion.

Case Discussion

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
