title: Importance of magnetic resonance imaging in osteoid osteoma: a case report.
abstract: A 23-year-old man presented with a femoral osteoid, which, because of its small calcified nidus and extensive osteoblastic response, could not be localized on bone scanning, computed tomography or angiography. Magnetic resonance imaging clearly defined the nidus and permitted excision with minimal morbidity.
