Long-term Follow-up of an Osteoid Osteoma of the Femoral Neck Treated with Percutaneous Procedure Under Computed Tomography Guidance

Anazawa U, Watanabe I, Mizuno S and Hotta H

Osteoid osteoma (OO) is a benign bone tumor, characteristic of both nocturnal pain alleviated by administration of non-steroid antiinflammatory drugs (NSAIDs) and a nidus which appears as a small, relatively radiolucent zone. X-ray finding of the nidus depends on the site of the lesion. Cortical OO is usually characterized by reactive sclerotic bone around the nidus. On the other hand, intramedullary or intra-articular OO may be difficult to identify because of less reactive sclerotic bone (Figures 1 and 2).
